Abstract
The invention provides a method for base stations under the same routing area to share tunnel resources, which comprises the following steps that: a terminal is switched to a new base station under a new routing area from an original base station under an original routing area; a tunnel is established between the original base station and the new base station and is subject to link maintenance through a heartbeat message; simultaneously the original base station informs the new base station of a base station list under the original base station and synchronously updates the base station list; the base stations under the same routing area mutually inform of the tunnel load conditions of the base stations; when the load of the original base station is extremely-heavy, the original base station analyzes the tunnel load conditions of other base stations under the original routing area and shares partial load per se to the base stations with low current load; and when the new base station does not receive the heartbeat message of the original base station for a long time, the new base station transmits messages to other base stations under the original routing area and requests the other base stations to take over the tunnel of the original base station. The method can ensure that tunnel loads of various base stations are balanced and the off-line rate of users can be greatly reduced by the timely transfer of the tunnel resources even if a certain base station is abnormal.
Description
Technical field
The present invention relates to wireless communication field, relate in particular to the method for base station share tunnel resources under a kind of same route district.
Background technology
In wireless communication system, when the sub-district switching had taken place to stride at the terminal, the tunnel can be set up for it in the base station, realizes the correct forwarding of message.Adopt this mechanism, the tunnel is based upon near the base station the cell boarder more, and the base station of cell boarder is because load is heavy, and offering quality of services for users will descend; And these base stations take place when unusual, and can cause can't be for the user provides normal service, even causes the user to go offline.
Because the tunnel, base station of inside, sub-district is correspondingly less, it is also little to load.Therefore, can consider the tunnel resource between sharing base, share load jointly.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention proposes the method for base station share tunnel resources under a kind of same route district, this method comprises:
The terminal switches to the new base station under the new route district from the former base station under the former route district; Set up the tunnel between former base station and the new base station; And carry out link through the tunnel heartbeat message and keep, new base station is informed with the station list former route district under in former base station simultaneously, and renewal synchronously; Base station under the same route district is notified the tunnel load condition of this base station mutually through message between the base station;
When tunnel, former base station overload of power, the tunnel load condition of other base station under the former route district will be analyzed in former base station, and the part tunnel load of oneself is given when the little base station of preload;
When new base station is not received the tunnel heartbeat message of former base station for a long time, other base station transmission message under the former route district will be given in new base station, require it to take over the corresponding tunnel on the former base station.
When tunnel, former base station overload of power; And then may further comprise the steps: 1, the tunnel load condition of other base station under the former route district that oneself preserves is analyzed in former base station; Find out a little base station conduct of load and share the base station, share the tunnel load message to its request of sending; 2, share after the base station receives that the tunnel load message is shared in the request of former base station, the tunnel load of analysis-by-synthesis oneself and the tunnel load that will obtain from former base station if can accept, are then replied acceptance, otherwise are replied refusal; If 3 former base stations receive that the acceptance of sharing the base station replys; Then the information in its tunnel that need share is issued and shared the base station; And the tunnel information on load of renewal oneself; Stop to be the tunnel service of sharing away, send out the tunnel load condition that message is given other these base stations of update notifications, base station under the former route district simultaneously; After sharing the information of receiving the tunnel of sharing in the base station; With the tunnel information on load that upgrades oneself; And set up the tunnel with the relevant base station in the tunnel of sharing and get in touch so that tunnel service to be provided, send out the tunnel load condition that message is given other these base stations of update notifications, base station under the former route district simultaneously; If receiving, 4 former base stations share rejecing response of base station; The tunnel load number that need share of minimizing then; And share the tunnel load message to sharing the base station request of sending once more, share the base station with repeating step 2 said processes, then; If former base station receives that the acceptance of sharing the base station replys, then processing procedure is identical with step 3; If receiving, former base station shares rejecing response of base station; Under the former route district that former base station will be preserved according to oneself except the said tunnel load condition of sharing other base station of residue outside the base station; Begin all said steps more than the repetition from step 1, perhaps reduce owing to the tunnel dismounting causes former base station load up to the request that has the base station to accept former base station.
When new base station is not received the tunnel heartbeat message of former base station for a long time, and then may further comprise the steps: 1, new base station sends the message of the former base station of request adapter associated tunnel for other base stations down, former route district; 2, after step 1 described request is received in other base stations under the former route district, analyze the tunnel load of oneself,, reply successful respond then for new base station, otherwise do not return message if can take over; 3, new base station selects a base station as taking over the base station according to the response message that receives, and sends the tunnel message of former base station to it; After taking over the base station and receiving the tunnel information of sending new base station, with upgrading own tunnel information on load, and set up tunnel relation so that tunnel service to be provided, send out the tunnel load condition of message simultaneously to other these base stations of update notifications, base station under the former route district with new base station; If receive for a long time 4 new base stations do not reply, then remove the connection at said terminal.
Beneficial effect of the present invention is: the tunnel load that 1, is positioned near the base station of cell boarder reduces greatly, can better for the user service be provided; 2, the tunnel load away from the base station of cell boarder improves, and greatly reduces the waste of base station resource; Even it is unusual that 3 certain base station occur,, promoted user's satisfaction because the timely transfer of tunnel resource also makes user's drop rate descend greatly.
Description of drawings
Fig. 1 is the process chart when base station a finds own current tunnel overload in the embodiment of the invention;
Process chart when Fig. 2 does not receive the tunnel heartbeat message of base station a for a long time for base station b in the embodiment of the invention.
Embodiment
Specify embodiment of the present invention below in conjunction with accompanying drawing.
In a wireless communication system, the terminal is an example from the new base station b that the former base station a under the former route district A switches under the new route district B.After the terminal switched, newly-built tunnel provided service for this terminal between base station a and the base station b, and base station a and base station b keep the operate as normal in tunnel through the tunnel heartbeat, and base station a informs base station b with the station list under the route district A.
Because newly-built tunnel, change has taken place in the tunnel load of base station a, and when upgrading own load, other base station synchronization under the transmission message requirement route district A is the load of the base station a of new record more.As shown in Figure 1; When base station a adds up the load of oneself,, need the application load sharing if find that current over-burden; Just analyze the load condition of other base station under the route district A that oneself writes down; Find a base station c that load is less, send the load sharing request, carry the tunnel number that to share in the message.After base station c receives request, analyze the load of oneself, and if receive the load that the tunnel of base station a will bring, if can receive, just send and accept to reply, reject response otherwise send.Base station a receives that the acceptance of base station c replys, and the tunnel information of sharing that just will just consult is issued base station c, stops to be the tunnel service of sharing away, upgrades own load simultaneously, sends the updating message of loading to other base station under the route district A.After base station c receives the tunnel of sharing, set up contact, formally take over these tunnel managements with relevant tunnel, opposite end.Base station c also upgrades the load of oneself, sends the load updating message to other base station under the route district A.If base station a has received rejecing response of base station c, then recomputate the load of oneself, the tunnel number that reduction need be shared sends the load sharing request for once more base station c.If base station c allows to accept, then handle with noted earlier consistent, if base station c still refuses, base station a will select suitable base station and carry out the load sharing negotiation in the residue base station under the route district A outside the c of base station.If base station a has attempted all base stations in tabulation load of failing to share, then select from the station list of initial route district A the base station to continue to consult again, up to having the base station to receive load or base station a causes the load reduction because the tunnel is finished at the terminal.
As shown in Figure 2, if base station b find tunnel heartbeat timer continuous 3 times overtime, just initiatively send request adapter a tunnel, base station load message to the base station route district A under.With base station a after this request is received in the base station of same route district A, analyze the load of oneself, if can take over, then return successful respond, do not answer otherwise do not respond.If base station b has received successful respond; Then select a base station d tunnel service to be provided as taking over the base station; Send associated tunnel information and give base station d; Keep the operate as normal in tunnel between the two through the tunnel heartbeat, base station d upgrades own load, sends the updating message of loading to other base station under the route district A.If base station b does not receive still after replying timer expiry and replys that then ending provides service for this user.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
