[0002] 在宽带码分多址系统(WCDMA)系统中当UE(用户设备)处于专用状态,也就是CELL_PCH, URA_PCH的时候,该UE在核心网中的处于PMM_C0NNECTED状态。 [0002] In the Wideband Code Division Multiple Access system (WCDMA) system, when a UE (User Equipment) is in a dedicated state, i.e. CELL_PCH, URA_PCH, when the UE in the core network is in a state PMM_C0NNECTED. 核心网保留了和该终端有关的匪CONTEXT(移动性管理上下文)。 CONTEXT core network retains bandit and the associated terminal (mobility management context). 核心网和基站控制器之间一直保留着专用的信令连接,以便及时在核心网和基站控制器之间交换信令。 Between the core network and the base station controller has retained a dedicated signaling connection to exchange signaling in time between the core network and a base station controller. 当需要传送上下行数据的时候,为了加快控制面和用户面的重建速度,地面接口之间的传输资源有可能被保留,比如Iub, Iur和Iu接口等。 When the uplink and downlink data needs to be transmitted, in order to accelerate the reconstruction speed control plane and the user plane, the transmission resource between the terrestrial interface is likely to be retained, such as Iub, Iur and Iu interfaces.

[0003] 当这些终端一直在服务区内的时候,网络和终端之间通过周期性的小区更新(对于CELL_PCH状态来说),周期性URA更新(对于URA_PCH来说状态)来保持网络和终端之间RRC(无线资源控制)状态的一致性。 [0003] When the terminals have been at the time of the service area, between the network and the terminal through a periodic cell update (for CELL_PCH state is), the periodic URA update (For the URA_PCH state) to hold the terminal and the network consistency between RRC (radio resource control) state.

[0004] 但是当这些终端满足"不在服务区"的条件的时候,在周期性更新流程触发之前, 网络和终端之间关于RRC的状态之间就会出现不一致。 [0004] However, when these terminals meet the conditions "out of service" of the time, before the periodic update process is triggered, and the terminal on the network between state between RRC will appear inconsistent. 这种状态如果保留的时间比较长的话,可能产生的不利后果有: If this state retention time is relatively long, the adverse consequences that may arise are:

[0005] 1、保留的传输层的资源没有得到有效利用; [0005] 1, the transport layer resource reservation is not effectively utilized;

[0006] 2、网络发起的寻呼流程会失败,而且如果不采取积极的措施,在结束状态不一致状况以前,后续的寻呼流程都会失败,这种情况降低了网络的性能。 [0006] 2, a network initiated paging process will fail, and if you do not take active measures, before the end of the state of inconsistencies, subsequent paging process will fail, this reduces the performance of the network.

[0034] 下面结合附图进一步详细说明本发明的具体实施例。 [0034] The following specific embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings. 本发明采用了寻呼触发的资源释放方法。 The present invention employs a method of paging resource release trigger. 首先规定采用本发明的前提条件: First, subject to the requirement of the present invention:

[0035] 1、被寻呼的终端在基站控制器中状态处于CELL_PCH或者URA_PCH [0035] 1, the paged terminal in the base station controller state is CELL_PCH or URA_PCH

[0036] 2、周期性更新流程的T305定时器距离超时大于或者等于Tl时间。 [0036] 2, the timer T305 is a periodic update process from the timeout time is greater than or equal to Tl. Tl大于O,小 Tl is greater than O, the small

于T305。 In T305. Tl和终端响应寻呼的过程以及实际的应用情况有关 Tl and the terminal processes the paging response and the actual circumstances of the application

[0037] 3、寻呼的结果,根据协议规定,会要求终端发送小区更新。 [0037] 3. Results paging, According to the protocol, will send a cell update request terminal.

[0038] 当终端,比如UE1,的状态和寻呼过程满足上述3个条件的时候,服务基站控制器(SRNC)根据实际的网络参数设置等待寻呼响应时间T2。 [0038] When a terminal, such as UE1, status and a paging process to satisfy the above three conditions, the serving base station controller (SRNC) a page response waiting time T2 according to the network parameters. T2是一个估算的参数,需要考虑寻呼过程中终端接收寻呼消息时候的DRX(非连续接收)周期,随机接入过程,当时公共信道FACH的负荷程度等因素。 T2 is an estimate of the parameter to be considered during the paging terminal receives a paging message when the DRX (Discontinuous Reception) period, a random access procedure, when the degree of load factor common channel FACH. 如果寻呼从核心网发起,并且核心网存在寻呼重发机制,那么T2还必须大于核心网的重发周期。 If the paging from the core network initiated, and the presence of the core network paging retransmission mechanism, it must be greater than T2 retransmission cycle core network. 在T2超时以前,如果收到了UE1的小区更新请求消息,那么表示UE1在服务区内,停止T2,后续的信令流程不在本发明范围之内;或者收到了核心网重发的寻呼消息,那么首先要停止T2,然后重新评估第二个条件决定是否继续上述过程。 In the T2 timeout before, if the UE1 receives a cell update request message, the UE1 indicates the service area, stop T2, subsequent signaling procedures not within the scope of the present invention; received paging message or retransmitted the core network, so first of all to stop T2, then re-evaluate the second condition to decide whether to continue this process. 如果T2超时了,那么就表示终端UE1不在服务区内,为了避免在背景技术中描述的不利后果,需要通过Iu接口释放请求消息,通知核心网开始释放有关的UEl上下文,资源和Iu接口上的专用连接等。 If T2 timeout, then it indicates that the terminal UE1 is not in the service area, in order to avoid the adverse consequences described in the background, you need to request a message via Iu interface release notify the core network began to release on UEl context-related resources and Iu interfaces dedicated connections.

[0039] 图l是终端在服务区的小区更新(响应寻呼)过程,具体如下:无线接口的寻呼类型1消息是由核心网101触发,可以是NAS消息,数据或者寻呼消息,也可以是由基站控制器102本身触发的寻呼消息,比如状态转换等。 [0039] Figure l is a terminal updates (paging response) in a cell during the service area, as follows: radio interface paging type 1 message is triggered by the core network 101, may be a NAS message, data or a paging message, also It may be a paging message from the base station controller 102 of the trigger itself, such as the state of conversion. 如果终端103在服务区内,那么会通过随机接入过程,发送小区更新请求消息,其原因就是响应寻呼。 If the terminal 103 in service area, it will pass the random access procedure, send a cell update request message, which is the reason for the paging response.

[0040] 图2是终端不在服务区的小区更新过程,具体如下:由核心网或者服务基站控制器触发了对某个终端的寻呼过程。 [0040] FIG. 2 is a cell update procedure of the terminal is not in the service area, as follows: the paging procedure is triggered by a certain terminal to a core network or the serving base station controller. 因为该终端处于CELL_PCH或URA_PCH状态,所以在空口发送的是寻呼类型l。 Since the terminal is in the CELL_PCH or URA_PCH state, the air interface is transmitted in the paging type l. 服务基站控制器在发送完PAGING TYPE1(寻呼类型1)消息以后,发现该终端的周期性小区更新或者URA更新的定时器距离超时还大于或者等于Tl时间,那么就设置一个寻呼过程的保护定时器T2(如果寻呼由核心网触发,而且核心网有重发机制,那么这个定时器需要大于核心网的重发定时器),然后等待终端寻呼响应。 After completion of the serving base station controller transmits PAGING TYPE1 (Paging Type 1) message, the terminal find periodical cell update or URA update timer times out further distance equal to or greater than the time Tl, then a paging procedure protective timer T2 (if the paging triggered by a core network, the core network and there is a retransmission mechanism, then this timer must be greater than the retransmission timer of the core network), then the terminal waits for a paging response. 如果T2超时,表明该终端不在服务区或者无法正常接入网络,也就是无法正常通讯。 If T2 timeout, indicating that the terminal is not in service or can not normally access the network, which is not normal communication. 服务基站控制器随后释放该终端的上下文,资源,并且通知核心网也释放该终端的上下文,资源以及Iu接口上的所有专用连接。 Serving base station controller then releases the context of the terminal, the resources, and notifies the core network context of the user is also released, all dedicated resources and the Iu interface connections. 后续的信令不在本发明范围之内。 Subsequent signaling is not within the scope of the present invention.

[0041] 图3是核心网发起CS(呼叫服务器)呼叫触发资源释放的流程图。 [0041] FIG. 3 is initiated by the core network CS (Call Server) resource release a flow chart of the call trigger. [0042] 核心网发起CS呼叫案例。 [0042] The core network initiates a CS call cases. 具体过程参考实施方法。 DETAILED procedure of Reference Example. [0043] 具体实施方法:核心网发起CS呼叫触发资源释放流程 [0043] specific implementation methods: CS core network initiates a call trigger resource release process

[0044] 终端UE2处于CELL PCH状态,并且已经设置T305进行状态保护。 [0044] The terminal UE2 in the CELL PCH state, and the state has been set T305 protected. 这时候有一个CS的呼叫从核心网触发。 At this time there is a CS call trigger from the core network.

[0045] 步骤1,服务基站控制器检查UE2是否处于CELL_PCH或者URA_PCH状态。 [0045] Step 1, the controller checks the serving base station UE2 is in CELL_PCH or URA_PCH state. 如果不是,转到步骤12 If not, go to step 12

[0046] 步骤2,发送寻呼类型1消息[0047] 步骤3,检查寻呼的原因。 [0046] Step 2, transmit the paging type 1 message [0047] Step 3, check paging reasons. 因为是从核心网发起的CS呼叫,所以终端会发起小区更新响应寻呼。 Because it is launched from the core network CS call, the terminal initiates a cell update response page. 否则如果不会触发寻呼响应过程,转到步骤13。 Otherwise, if the process does not trigger paging response, go to step 13.

[0048] 步骤4,检查UE2正在运行的T305剩余的时间满足大于Tl的要求,如果不是,转到步骤13。 [0048] Step 4, check the remaining running time T305 UE2 meet is greater than Tl, if not, go to step 13.

[0049] 步骤5,设置寻呼保护定时器T2 [0049] Step 5, protected paging set the timer T2

[0050] 步骤6,在T2超时前,如果收到了UE1的小区更新消息,然后步骤10 [0050] Step 6 before T2 expires, if UE1 receives a cell update message, and then step 10

[0051] 步骤7,在T2超时前,如果收到了核心网重发的寻呼消息,转到步骤11 [0051] Step 7, before T2 expires, if the received paging message retransmission core network, go to Step 11

[0052] 步骤8,如果T2超时,那么判断UE2不在服务区 [0052] Step 8, if the T2 times out, the service area is determined not UE2

[0053] 步骤9,服务基站控制器发送Iu接口释放请求消息给核心网 [0053] Step 9, the serving base station controller transmits an Iu interface to the core network release request message

[0054] 步骤10,停止T2,随后的信令流程不在本发明中范围内 [0054] Step 10, stop T2, within the scope of this invention, the following signaling flow

[0055] 步骤11,停止T2,然后转到步骤4 [0055] Step 11, stop T2, then go to step 4

[0056] 步骤12,按照其他状态进行处理 [0056] Step 12, the processing in other state

[0057] 步骤13,结束。 [0057] Step 13 ends.

[0058] 以上所述仅为本发明的较佳实施例,并非用来限定本发明的实施范围;凡是依本发明所作的等效变化与修改,都被本发明的专利范围所涵盖。 [0058] The foregoing is only preferred embodiments of the present invention, not intended to limit the scope of embodiments of the present invention; under this all equivalent modifications and variations made to the invention, is encompassed by the scope of the present invention.
