Embodiment
Specific embodiment below with reference to each description of drawings of the present invention base station call balance method of the present invention.For ease of explanation, suppose that in the following detailed description personal terminal is a mobile phone.
Fig. 2 shows the schematic flow diagram of first kind of scheme of base station call balance method of the present invention.As shown in Figure 2, start base station automatic traffic equilibrium function after, step S20 base stations detected Traffic Channel busy/idle condition.If judge that at step S30 this base station is in the Traffic Channel busy state, then system is notified to corresponding personal terminal at step S40 with this busy state of base station, makes this personal terminal not reattempt to this base station and sets up communication link; Otherwise system will notify corresponding personal terminal service in base station channel to be in idle condition at step S50, so personal terminal can utilize common working method to attempt setting up communication to this base station.After said process, judge whether to close base station automatic traffic equilibrium function at step S60, if do not close, then system restarts to carry out from abovementioned steps S20; Otherwise, to finish to carry out above-mentioned base station automatic traffic equilibrium function at step S70, the base station is according to common working method work.
Introduce an embodiment of this scheme below.Before introducing this embodiment, be necessary simply to introduce earlier PHS system control channel operation principle.In the PHS system, three class down control channels are arranged, be respectively broadcast channel (BCH), paging channel (PCH) and access control channel (SCCH), wherein paging channel is used to send called notice, access control channel is used for to the handset allocation Traffic Channel, and the content in the broadcast channel is used for current running status of base station broadcast system and relevant parameter.Message in broadcast channel is divided three classes again, is respectively radio channel information broadcast (Radiochannel information broadcasting message), system information broadcast message (System information broadcasting message), electrical secondary system information broadcast message (Second system information broadcasting message).This three classes message alternately sends in broadcast channel.Wherein in system information broadcast message, there is the special field that length is 5 bits, is called base station information " CS information ", be used to report the current type of base station.The 5th bit value of this field is to mean that the base station is current at 0 o'clock to be upstate that promptly mobile phone can be chosen in this base station under and work or standby.Mean that when this bit value is 1 the base station is current for down state, mobile phone can not be chosen in this base station under and work or standby.
In the present embodiment, realize that the traffic balance function is to utilize " CSinformation " this bit, are got up in it and BTS service channel occupancy combinations of states, make the busy-idle condition of base station notify the terminal use by broadcast in time.With 7 channel base station is example, to detect 7 Traffic Channels whole when occupied when the base station, just the base station information in the system broadcast message that sends later on is set to the base station down state, this base station just is in the state of " temporary transient disappear " for mobile phone like this, mobile phone just can not send new link setup request to this base station, and the mobile phone of standby also can be sought other base station standby again under this base station.And detect when idle channel occurring when the base station, base station information in the system broadcast message that sends later on again is set to the base station upstate, this base station is just got back in the middle of " sight line " of mobile phone again like this, and mobile phone can send link setup request or standby below this base station to it.
Develop the process of this traffic channel equilibrium function also finds the present inventor, for save battery power, prolongs standby time, some mobile phone with holding state receives only the message of paging channel under holding state, do not receive the message of broadcast channel.Have only the broadcast reception indication " Broadcasting receptionindication " in the paging channel to change, could notify mobile phone to collect content in the broadcast channel again.Therefore under the situation of this mobile phone with holding state, only revise the effect that system broadcast message can not play timely notice mobile phone.When the base station need notify the upstate of cellular base station to change by broadcast, need to revise earlier the broadcast reception indication in the paging channel, revise system broadcast information subsequently again, so just can in time notify mobile phone the change of base station upstate.
Fig. 5 shows the above-mentioned first kind of corresponding schematic representation of apparatus of scheme with first kind of base station call balance method of the present invention.For purposes of simplicity of explanation, only show the part that personal communication of the present invention inserts (PAS) system among the figure, promptly only shown a base station 2, and with these base station 2 associated two personal terminal 5.But, it will be understood by those skilled in the art that in same PAS system, have a plurality of base stations, and each base station can interrelate with a plurality of personal terminal.As shown in Figure 5, in base station 2, be provided with a notifying device 501 and a recovery device 500, and this notifying device 501 also comprises reception message indicating unit 502 and busy state notification unit 503.When base station 2 was in the Traffic Channel busy state, reception message indicating unit 502 these base stations 2 of modification were indicated by the broadcast reception in the paging channel of system's control channel and are notified corresponding personal terminal 5 receiving system broadcasts.Busy state notification unit 503 is revised base stations 2 and is sent the content of the system information broadcast message of personal terminal 5 to by the broadcast channel in system's control channel, promptly by the 5th bit position 1 with the base station information in the described system information broadcast message the busy information of indication base station 2 Traffic Channels is embedded in this broadcast.Personal terminal 5 is receiving by the broadcast reception indication back that receives message indicating unit 502 transmissions from system broadcast channel receiving system information broadcast message, thereby make personal terminal 5 recognize the heavy traffic state of base station 2, so make this personal terminal 5 no longer attempt setting up communication to this base station 2.When base station 2 when professional channel busy state is got back to the service condition idle condition, this personal terminal 5 by recovery device 500 this idle condition of base station 2 is notified to corresponding personal terminal 5, so can be attempted communicating by letter with 2 foundation of this base station by common working method.Thereby realize base station automatic traffic equilibrium function.
Fig. 3 shows the schematic flow diagram of second kind of scheme of base station call balance method of the present invention.As shown in Figure 3, after starting this base station call balance, at first in the operating state of S110 base stations detected.Then judge at step S120 whether this base station is in the Traffic Channel busy state.If answer is a "Yes", then will all shield to the control information that personal terminal sends from system's control channel, so this personal terminal no longer attempts setting up communication to this base station at step S130.If answer is a "No", judge that then this base station is in the Traffic Channel idle condition, system transmits control message to personal terminal according to common mode at step S140 control channel.After finishing aforesaid operations, judge at step S150 whether this traffic balance function closes.If do not close, then return the operation that step S110 continues repeated execution of steps S110 to S150; Otherwise the traffic balance function is closed in the base station, adopts common working method work.
Describe a specific embodiment of above-mentioned second kind of scheme now in detail.Is example at this with 7 channel base station.As can see from Figure 3, second kind of scheme is more direct, to detect 7 Traffic Channels whole when occupied when the base station, just the content with all bits in the later control channel changes " 1 " transmission entirely into, for mobile phone, can't parse the information that sends on this base stations control channel so fully, its effect is equivalent to this base station " the temporary transient disappearance ", promptly to mobile phone " shielding " all control informations of this base station to its transmission, so mobile phone can not send new link setup request to this base station, also can't standby under this base station, must seek other base stations.And when the base station detects channel and reverts to idle condition, resend correct control channel information again, and this base station is just got back in the middle of " sight line " of mobile phone again like this, and mobile phone can send link setup request or standby under this base station to it.
Fig. 6 shows the above-mentioned second kind of corresponding schematic representation of apparatus of scheme with base station call balance method of the present invention.Part identical with the structure of Fig. 5 in the structure of this figure is represented with identical Reference numeral, does not repeat them here.As shown in the figure, be provided with recovery device 500 and control information screening arrangement 601 in the base station 2.When base station 2 is in the Traffic Channel busy state, described control messages screening arrangement 601 is communicated by letter thereby make this personal terminal 5 not attempt setting up to the base station 2 that is in the Traffic Channel busy state by making all control informations to these personal terminal 5 shieldings to all bit sets of the information of corresponding personal terminal 5 transmissions via system's control channel.When base station 2 when professional channel busy state is got back to the service condition idle condition, recovery device 500 can send control information base station 2 by common working method to corresponding personal terminal 5, so this personal terminal 5 can be attempted communicating by letter with 2 foundation of this base station by common working method.Thereby realize base station automatic traffic equilibrium function.
Fig. 4 shows the schematic flow diagram of realizing the method for base station automatic traffic equilibrium function in conjunction with above-mentioned two kinds of schemes.As shown in Figure 4, personal communication connecting system (PAS) at first judges whether to start base station automatic traffic equilibrium function at step S210.If do not start this function, then the base station is by common working method work.If start this function, then further judge to start above-mentioned any scheme at step S220.If start first kind of scheme, then carry out above-mentioned first kind of scheme as shown in Figure 2.If start second kind of scheme, then carry out above-mentioned second kind of scheme as shown in Figure 3.If, then continue by common working method work in this base station of step S230 at step S210 judgement startup base station automatic traffic equilibrium function.
The following describes a specific embodiment of the described scheme of Fig. 4.
In order to realize the automatic traffic Balance Control function of base station, can in the Control Software of base station, increase several parameters newly, by adjustment, can realize the traffic balance between the base station effectively to these parameters.Earlier as follows to each parametric description respectively:
Parameter one: functional switch
This parameter is used to determine whether the base station opens the traffic automatic balance function.For example can stipulate that this parameter value is set to 01, the traffic balance function will be carried out according to scheme one in the base station; This parameter is made as 02, and the traffic balance function will be carried out according to scheme two in the base station; Be made as 00 or other values, the traffic balance function will be closed in the base station.When this parameter is made as 01 or 02, below four parameters work beginning.
Parameter two: base station busy state activation threshold
When base station automatic traffic equilibrium function switch is unlocked, base station idle channel number will enter busy state automatically when being less than this threshold value, content (scheme two) in the control channel will or directly be destroyed by modification system broadcast information message (scheme one) in the base station this moment, this base station of notice mobile phone is temporarily unavailable, like this mobile phone can't with this base station set up new get in touch or standby under this base station, thereby avoid the further increase of this busy base station call, and force other base stations of remaining traffic direction.It is emphasized that the mobile phone of conversing in base station therewith can not be affected.The unit that this parameter adopts is the remaining idle channel number in base station, and for example, for 7 channel base station, the configuration scope of this parameter is 00-06, and for the group control base station of 15 channels, the configuration scope of this parameter is 00-0E (14 idle channel).The default parameter value of suggestion is 00, promptly when all channels of base station are taken entirely, just enters busy state.
Parameter three: base station idle condition activation threshold
Equally, when base station automatic traffic equilibrium function switch open, base station idle channel number will enter idle condition from busy state when surpassing this threshold value, it is normal operating conditions, the base station was revised system broadcast information (scheme one) once more or was recovered via control channel send control information (scheme two) this moment, notice mobile phone this base station reverts to available, so mobile phone can carry out normally associate or standby under this base station with this base station.This means that normal condition can be recovered in the base station when the traffic busy state of base station is eased, up to the busy state that enters next time.By the remaining idle channel decision in base station, for example, for 7 channel base station, the configuration scope of this parameter is 01-07 equally in the unit of this parameter, and for group control base station, the configuration scope of this parameter is 01-0F (15 idle channel).We are 01 by the default parameter of suggestion, and promptly when an idle channel appears in the base station, the base station will enter idle condition by busy state.The value that it should be noted that this parameter should be greater than base station busy state activation threshold, otherwise logical miss will occur.
Parameter four/parameter five: the base station is busy/the idle condition retention time
In order to prevent that the base station from frequently switching between busy state and idle condition, in system, be provided with the base station busy/idle condition retention time parameter.For instance, when the base station is in busy state, be not when satisfying the idle condition activation condition, just to switch to idle condition immediately, but continue to keep the regular hour at busy state, during this period of time, all the time satisfy the idle condition activation condition if the base station detects the channel occupancy number, the base station just enters idle condition.If during this period of time, the base station detects letter and takies several idle condition activation conditions that do not satisfy, then busy state is continued to keep in the base station, reach the idle condition activation condition once more up to detect the channel occupancy number next time, timing is restarted in the base station, if can satisfy the just generation state switching of idle condition activation condition in the retention time always.
Therefore, note that BTS service channel clear alleged among the present invention is meant that this base station has quantitatively idle business channel more than or equal to base station idle condition activation threshold in idle condition in the retention time; And being meant this base station, BTS service channel busy state has quantitatively idle business channel in the retention time smaller or equal to base station busy state activation threshold at busy state.
Fig. 8 illustrative these a pair of states of parameter four/five switch retention time roles, suppose that here the retention time of these two states all was set to for 2 seconds.Be not difficult to find out that if the state that is not provided with switches the retention time, the base station will be switched back and forth, and is very frequent, shown in the curve above among Fig. 8 between busy and idle condition.And after being provided with these two states and switching the retention time, it is level and smooth relatively that curve becomes, shown in a following curve among Fig. 8, that is, and the base station only condition satisfy and more stable situation under just can change by the generation state.Particularly, also can of short durationly take the service in base station channel during owing to the mobile telephone registration registration, because registration causes base station state change, this two parameters must be set in order to prevent for the PHS system.Here Jian Yi default parameter value was for 5 seconds.
In the present invention with the content of a byte represent above-mentioned base station busy/the idle condition retention time, so these two retention times all can in 0-255 scope second, be provided with.
Result from practical application, the effect that two kinds of schemes reach is suitable substantially, then a kind of scheme has better handset compatibility (mobile phone of individual types is not abideed by the regulation of PHS agreement fully and correctly handled the situation that " CS information " changes, and therefore there are some compatible problems in first kind of scheme in present stage).Therefore, though above-mentioned two kinds of schemes all can realize automatic traffic equilibrium function in base station in the PAS system, in the situation that the mobile phone compatibility is had relatively high expectations, second kind of scheme adopted in suggestion usually.
Fig. 7 shows the corresponding schematic representation of apparatus of method with above-mentioned first kind and the second kind scheme that combines base station call balance method of the present invention.The similar of this figure and Fig. 5 and Fig. 6, wherein identical part is represented with identical Reference numeral, is not repeated them here.As shown in Figure 7, be provided with recovery device 500 and function selection device 701 in the base station 2.Function selection device 701 also comprises parameter set unit 702, base station operating state detecting unit 703, parameter detecting unit 704 and base station automatic traffic equilibrium function performance element 705.Parameter set unit 702 is used to the work of control base station 2 and traffic balance function on parameter, the first traffic balance functional parameter, the second traffic balance functional parameter is set.Base station operating state detecting unit 703 is used for the traffic channel state of base stations detected 2, if this base station 2 is in the Traffic Channel idle condition, then makes this base station 2 according to common working method work.Be in the Traffic Channel busy state if detect base station 2, then system makes parameter detecting unit 704 detect traffic balance function on parameter, the first traffic balance functional parameter, the second traffic balance functional parameter of this base station.When this traffic balance function on parameter during not for the value of enabling, make base station 2 according to common working method work, do not carry out base station automatic traffic equilibrium function; When this traffic balance function on parameter is the value of enabling, when any in this first traffic balance functional parameter and the second traffic balance functional parameter is for the value of enabling simultaneously, then carry out relevant base station automatic traffic equilibrium function.Specifically, when being the value of enabling by the described parameter detecting unit 704 detected traffic balance function on parameters and the first traffic balance functional parameter, the base station call balance method that base station automatic traffic equilibrium function performance element 705 is carried out as shown in Figure 2; This base station automatic traffic equilibrium function performance element 705 is carried out as above-mentioned base station call balance method shown in Figure 3 when being the value of enabling by parameter detection equipment 704 detected traffic balance function on parameters and the described second traffic balance functional parameter.For example, traffic balance function on parameter can be made as 00 or other values, the value of enabling of the first traffic balance functional parameter is set to 01, the value of enabling of the second traffic balance functional parameter is made as 02.Certainly, it will be understood by those skilled in the art that being provided with of above-mentioned parameter value can also have many kinds possibilities.
Though base station of the present invention automatic traffic equilibrium function is preferably realized by relevant Control Software.But, also can realize in conjunction with the described device of Fig. 5-7 with above-mentioned.And those skilled in the art can expect the device that other is used to realize this base station automatic traffic equilibrium function at an easy rate.
After finishing this function development, the present inventor has carried out on-the-spot test to it as a new function of base station, with validity and the practicality of verifying it.Fig. 9 and Figure 10 are respectively telephone traffic and the blocking rate contrast schematic diagrames of using automatic traffic equilibrium function front and back, base station of the present invention in the PAS system.
Here be example with 7 channel base station, after opening the traffic balance function, set quadrinomial parameter is respectively:
Base station busy state activation threshold: 1 idle time slot
Base station idle condition activation threshold: 2 idle time slots
The base station is busy/the idle condition retention time: and 5 seconds
From Fig. 9 and Figure 10, be not difficult to find out, telephone traffic slightly reduces than the base station of not adopting the traffic balance function when having adopted base station busy of traffic balance function, about about 1 Ireland, but still can maintain busy level about 4Erl (7 channel base station can provide the telephone traffic of 3.5Erl under for 5% situation approximately at blocking rate), this illustrates that the telephone traffic of this base station has obtained control effectively, that part of telephone traffic that exceeds the base station ability to bear is shunted away effectively, has realized the purpose of traffic balance.
And on the other hand, when adopting traffic balance function base station busy blocking rate well below the base station of not adopting the traffic balance function, basic controlling about 5%, and do not open the base station of this function when busy blocking rate on average be about 25%.Also can accomplish the end in view in this, this improvement will help to improve the jointing-success-rate of calling and the speed that continues.
The present inventor also tests the group control base station of 15 channels, has also obtained satisfied result.In addition the various type of cell phone of present existence have been carried out compatibility test, fact proved that this function does not have significant side effects when especially adopting scheme two.Figure 11-the 13rd, present inventor carry out the resulting result of above-mentioned test.Figure 11 is that its telephone traffic situation contrasts before and after enabling base station of the present invention automatic traffic equilibrium function; Figure 12 is that the blocking rate situation contrasts before and after enabling base station of the present invention automatic traffic equilibrium function; Figure 13 enables the compatibility test result who various model mobile phones is carried out behind the automatic traffic equilibrium function of base station of the present invention.According to the effect of these tests, can reach a conclusion, the traffic balance function helps to provide the overall performance of PAS system between this base station of the present invention.By introducing base station automatic traffic equilibrium function, traffic between can the active balance base station, the high-power resistance control base station of busy section of town (as be positioned at) is diverted to idle base station (as the small-power base station of unfavorable high-power base station, installation site or mixed networking) from busy base station telephone traffic, reduce the blocking rate of busy base station on the one hand, improve the speed that continues and shorten connecting time, improve the utilance of other BTS service channels on the other hand, make user's investment obtain the fullest reasonable use, reduce cost.
