Description
Technical field
The present invention relates to a kind of communication technology, relate in particular to the method and system of a kind of subscriber equipment (UE) condition managing.
Background technology
(the 3rd Generation Partnership Project of 3G (Third Generation) Moblie standardization body, 3GPP) in order to strengthen the competitiveness of future network, studying a kind of brand-new evolvement network, comprise evolution system framework (System Architecture Evolution, SAE) and the Access Network of Long Term Evolution (Long TermEvolution, LTE), described evolution system framework comprises evolution block core net.The Access Network of described evolution is also referred to as evolution wireless access network (Evolved Radio Access Network, ERAN), be used to subscriber equipment (User Equipment, UE) provide the functions such as wireless access of evolvement network, evolution block core net is used to subscriber equipment that the mobile management of evolvement network is provided, with functions such as the exchange of external network and routes.As shown in Figure 1, described evolvement network comprises: the Access Network of evolution; (Policy and Charging Rule Function PCRF), is used for policy control decision and flow based charging controlled function to the "Policy and Charging Rules Function entity; (Home Subscriber Server HSS), is used for storing user subscription information to home network server; And evolution block core net.
Framework shown in Figure 1 does not also mean that final SAE, last framework may with this framework difference to some extent, this patent does not limit.
Defined the state of three kinds of subscriber equipmenies among the present SAE: attachment state (LTE_DETACHED), idle condition (LTE_IDLE), state of activation (LTE_ACTIVE).Wherein the LTE_DETACHED state is the state of UE when not being linked into the SAE/LTE system; LTE_IDLE is meant that evolution Access Network side does not have the Radio Resource and the context of subscriber equipment, does not have signaling to connect between evolution Access Network and the evolution block core net, after downlink data arrives evolution block core net, after needing to trigger the paging flow process, could down send; LTE_ACTIVE is meant that there be the Radio Resource and the context of subscriber equipment in evolution Access Network side, exists signaling to connect between evolution Access Network and the evolution block core net, and subscriber equipment can normal process context data and signaling message under this state.Status of user equipment can be changed mutually.Can be non-Active Timer overtime (that is, not having professional arrival for a long time) opportunity that status of user equipment is changed into the LTE_IDLE state from the LTE_ACTIVE state; Status of user equipment can be professional arrival from the opportunity that LTE_IDLE changes into the LTE_ACTIVE state; The LTE_DETACHED state is the state of UE when withdrawing from the SAE/LTE connecting system; Wherein, as shown in Figure 2, the flow process that status of user equipment is changed into the LTE_IDLE state from the LTE_ACTIVE state is as follows:
Step 21, when evolution Access Network decision changes state of user to the LTE_IDLE state, the evolution Access Network sends and discharges request message to evolution block core net.
After step 22, evolution block core net receive and discharge request message, send release command message to the evolution Access Network, order evolution Access Network changes state of user to the LTE_IDLE state.
Step 23, evolution Access Network discharge user's radio resource and context, send Release complete then to evolution block core net.
In the present user's set condition managing mechanism, the evolution Access Network decides the change of status of user equipment according to a non-Active Timer of own internal configurations, if just the user of LTE_ACTIVE state does not have business at non-Active Timer in the time, then the evolution Access Network is changed into the LTE_IDLE state with status of user equipment.
Yet, there are the following problems for above-mentioned user's set condition managing mechanism: subscriber equipment is when the LTE_IDLE state, evolution block core net will not send downlink data after receiving the downlink data of subscriber equipment, but trigger the paging flow process, by the paging flow process state of subscriber equipment is changed into the downlink data packet that could send the user behind the LTE_ACTIVE state, so the LTE_IDLE state can have influence on the paging flow of core-network side; If it is low that the non-Active Timer duration in the evolution Access Network was provided with, subscriber equipment changes to the LTE_IDLE state in the short period of time, will cause the paging flow in the network to increase greatly like this; In order to reduce the paging flow, generally speaking, core net need send order to its all evolution Access Networks of managing, to revise the non-Active Timer of subscriber equipment in all evolution Access Networks, therefore, inconvenient paging flow adjustment.In addition, under the scene that the evolution Access Network is shared, it is the equipment of the core network that a plurality of operators have oneself separately, but the evolution access network equipment is to share to use, each operator may be according to the situation of own network equipment operation under this scene, different non-Active Timer durations need be set, owing in existing evolution Access Network, have only a non-Active Timer, thereby can not make each operator different non-Active Timer durations is set according to the situation of own network equipment operation.
