Embodiment
Further describe specific embodiments of the invention below in conjunction with accompanying drawing.The method for releasing resource that the present invention has adopted paging to trigger.At first regulation adopts precondition of the present invention:
1, paged terminal state in base station controller is in CELL_PCH or URA_PCH
2, periodically update the T305 timer overtime T1 of the being greater than or equal to time of distance of flow process.T1 is greater than 0, less than T305.The applicable cases of the process of T1 and terminal response paging and reality is relevant
3, the result of paging according to the agreement regulation, can require terminal to send cell update.
Work as terminal, such as UE1, state and paging when satisfying above-mentioned 3 conditions, serving BS controller (SRNC) is provided with according to the network parameter of reality and waits for page response time T 2.T2 is an estimated parameters, DRX (discontinuous reception) cycle when need considering terminal paging receiving message in the paging, random access procedure, the factors such as the load of machinery systems of common signal channel FACH at that time.If paging is initiated from core net, and there is calling retransmission mechanism in core net, and T2 also must be greater than the repetition cycle of core net so.Before T2 is overtime, if received the cell update request message of UE1, represent that so UE1 in service area, stops T2, follow-up signaling process is not within the scope of the invention; Perhaps received the beep-page message that core net is retransmitted, so at first will stop T2, whether second conditional decision of reappraising then continues said process.If T2 is overtime, so just represent in terminal UE 1 out of reach,, need to discharge request message by the Iu interface for fear of the negative consequence of in background technology, describing, the notice core net begins to discharge relevant UE1 context, and resource is connected with special use on the Iu interface etc.
Fig. 1 is cell update (response paging) process of terminal at service area, specific as follows: the paging Class1 message of wave point is to be triggered by core net 101, can be NAS message, data or beep-page message, also can be the beep-page messages that trigger by base station controller 102 itself, such as state exchange etc.If terminal 103 in service area, can be passed through random access procedure so, send the cell update request message, its reason responds paging exactly.
Fig. 2 is the cell updating course of terminal out of reach, and is specific as follows: triggered paging to certain terminal by core net or serving BS controller.Because this terminal is in CELL_PCH or URA_PCH state, so be the paging Class1 what eat dishes without rice or wine to send.The serving BS controller is after sending PAGING TYPE1 (paging Class1) message; finding that timer distance that the periodic cell update of this terminal or URA upgrade is overtime also is greater than or equal to the T1 time; the protection timer T2 that a paging so just is set is (if paging is triggered by core net; and core net has retransmission mechanism; this timer need be greater than the retransmission timer of core net so), wait for the paging terminal response then.If T2 is overtime, show this terminal out of reach or normal access network, just can't normal communication.The serving BS controller discharges the context of this terminal subsequently, resource, and the notice core net also discharges the context of this terminal, the special-purpose connection of all on resource and the Iu interface.Follow-up signaling is not within the scope of the invention.
Fig. 3 is that core net is initiated the flow chart that CS (call server) calls out the release of triggering resource.
Core net is initiated CS and is called out case.Detailed process reference implementation method.
Specific implementation method: core net is initiated CS and is called out the triggering resource release flow
Terminal UE 2 is in CELL PCH state, and T305 has been set carries out state protection.At this time there is the calling of a CS to trigger from core net.
Step 1, serving BS controller check whether UE2 is in CELL_PCH or URA_PCH state.If not, forward step 12 to
Step 3, the reason of inspection paging.Because be to call out, so terminal can be initiated cell update response paging from the CS that core net is initiated.Can not trigger the page response process else if, forward step 13 to.
Step 4 is checked the satisfied requirement greater than T1 of remaining time of T305 that UE2 is moving, if not, forward step 13 to.
Step 5 is provided with paging protection timer T2
Step 6 is before T2 is overtime, if received the cell update message of UE1, step 10 then
Step 7 before T2 is overtime, if received the beep-page message that core net is retransmitted, forwards step 11 to
Step 8 if T2 is overtime, is judged the UE2 out of reach so
Step 9, serving BS controller send the Iu interface and discharge request message to core net
Step 10 stops T2, and signaling process subsequently is not in the present invention in the scope
Step 11 stops T2, forwards step 4 then to
Step 12 is handled according to other states
Step 13 finishes.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all contained by claim of the present invention.
