The main function is to provide users with higher service rates and lower the cost of using high-speed services. Insufficient coverage of distributed cellular wireless communication systems. The advantages of home base stations are affordable, convenient, low power output, plug and play, and more. The home base station can be directly connected to the core network. As shown in FIG. 1 , the home network base station gateway can also access the core network, as shown in FIG. 2a and FIG. 2b. The main functions of the home base station gateway are: verifying the security of the home base station, processing the registration of the home base station, performing operation and maintenance management on the home base station, configuring and controlling the home base station according to the operator's requirements, and exchanging data of the core network and the home base station. The access gateway may be an S-GW (Serving Gateway), a P-GW (Packet Data Network Gateway), a SGSN (Serving GPRS Support Node), a GGSN (Gateway GPRS Support Node) , Gateway GPRS Support Node ). In addition to supporting access to the mobile core network, the home base station can also support local IP access functions, enabling local access to other IP devices or the Internet of the home network. As shown in Figure 1, Figure 2a and Figure 2b, the addition of the local gateway can provide strong support for the local IP access technology. The implementation of the local IP access can use the multi-PDN (Packet Data Network) connection method. That is, the local IP access connection and the non-local IP access connection can be implemented by using different PDN connections), and the core network access and the local IP access function can be simultaneously implemented by establishing a connection, and the local gateway can be combined with the wireless side network element. It can also be separated from the wireless side network element. The local gateway acts as a gateway for external access to an external network (such as the Internet), providing address allocation, accounting, packet filtering, policy control, data offloading, NAS (Non-Access-Stratum, Non-Access Layer) /S 1 -AP/RANAP (Radios Access Network Application Part, Radio Access Network should Partial)/GTP (General Tunneling Protocol)/PMIP (Proxy Mobile IP)/MIP (Mobile IP, Mobile IP) message parsing, NAT (Network Address Translation), Local IP access policy routing and execution functions. The gateway can be combined with a home base station. Taking the LTE (Long Term Evolution) mobile communication network architecture as an example, FIG. 3a and FIG. 3b show schematic data flows of local IP access of the home base station system. Based on the home base station system architecture of FIG. 1, FIG. 4 shows a flow chart of a home base station system initiating a paging procedure for an idle user when data is accessed from a local IP in the prior art. The specific steps are described as follows:
步骤 401 , 在收到发往终端的数据后， 本地网关将緩存该数据； 步骤 402, 本地网关向移动性管理实体发送下行数据通知消息； 步骤 403 , 移动性管理实体回复下行数据通知响应； 步骤 404, 移动性管理实体向跟踪区内的所有基站发送寻呼消息， 携带 终端标识； 如果本地 IP访问的家用基站仍然属于终端的跟踪区内，则此处的寻呼消 息需要发送给本地 IP访问的家用基站。 步骤 405, 接收到寻呼消息后， 家用基站将对终端进行寻呼； 步骤 406, 如步骤 404所述， 移动性管理实体向跟踪区内的基站发送寻 呼消息； 该步与步骤 404并行； 步骤 407, 接收到寻呼消息后， 基站将对终端进行寻呼； 步骤 408, 获取寻呼信息后， 终端执行服务请求过程。 由于本地 IP访问不具有移动性，在终端移动到其他基站时， 其他基站无 需对本地访问的数据提供业务连续性保障， 因此对于现有寻呼方式（如上流 程所示寻呼整个跟踪区的基站） ， 即便终端在目标家用基站下可以收到寻呼 消息并重新建立目标家用基站的本地 IP连接，但非移动性的特点决定了源家 用基站已緩存的下行数据无法被终端获取， 唯独当终端位于源家用基站下才 能正确地接收处理该下行緩存数据。 因而， 对整个跟踪区基站进行寻呼的方 式在很大程度上造成了寻呼消息的冗余、 空口资源的浪费， 并加重了移动通 信系统的处理负担。 Step 401: After receiving the data sent to the terminal, the local gateway will cache the data. Step 402: The local gateway sends a downlink data notification message to the mobility management entity. Step 403: The mobility management entity replies with the downlink data notification response. 404. The mobility management entity sends a paging message to all base stations in the tracking area, and carries the terminal identifier. If the home base station accessed by the local IP still belongs to the tracking area of the terminal, the paging message here needs to be sent to the local IP access. Home base station. Step 405: After receiving the paging message, the home base station will page the terminal. Step 406, as described in step 404, the mobility management entity sends a paging message to the base station in the tracking area; the step is parallel to step 404; Step 407: After receiving the paging message, the base station will page the terminal. Step 408: After obtaining the paging information, the terminal performs a service request process. Since the local IP access does not have mobility, when the terminal moves to other base stations, the other base stations do not need to provide service continuity guarantee for the locally accessed data, so the existing paging mode is used (the base station of the entire tracking area is paged as shown in the above process). ), even if the terminal can receive the paging message and re-establish the local IP connection of the target home base station under the target home base station, the non-mobility characteristic determines that the downlink data buffered by the source home base station cannot be acquired by the terminal, only when the terminal The terminal is located under the source home base station to correctly receive and process the downlink buffer data. Thus, the party that pages the entire tracking area base station To a large extent, the redundancy of paging messages and the waste of air interface resources are caused, and the processing load of the mobile communication system is increased.

本发明的较佳实施方式 本发明的构思是：移动性管理实体在收到本地 IP访问触发的下行数据通 知后， 仅向所述本地 IP接入的无线侧网元发起寻呼终端的操作。 移动性管理实体可以为 MME ( Mobility Management Entity, 移动管理单 元）、 MSC ( Mobile Switching Centre,移动交换中心）或 SGSN( Serving GPRS Support Node, 服务 GPRS支持节点） 。 无线侧网元可以是基站、 家用基站、 RNC (无线网络控制器， Radio Network Controller ) 、 家用基站网关、 数据分流功能实体。 无线侧网元可以 与本地网关合设。 优选地， 移动性管理实体通过以下方法之一判断收到的下行数据通知是 否为本地 IP访问触发的：判断发起下行数据通知的网元是否为无线侧网元或 本地网关（可通过源地址进行判断 )； 判断下行数据通知中是否有本地 IP指 示（该指示可以是本地网关或无线侧网元加的）。 具体地， 对于第一种方式： 如果移动性管理实体发现下行数据通知为本地网关或无线侧网元发起， 则判 断下行数据为本地 IP访问触发的下行数据。对于第二种方式： 如果移动性管 理实体发现下行数据通知消息中包括了本地 IP指示，即表示下行数据为本地 IP访问触发的下行数据， 则判断下行数据为本地 IP访问触发的下行数据。 本地 IP访问的无线侧网元可以与本地网关地址相同， 本地 IP访问的无 线侧网元与本地网关合设。 当存在家用基站网关的情况下， 可以通过隧道方式区分寻呼消息是核心 网触发的还是本地 IP触发的， 即在移动性管理实体和家用基站网关之间，对 本地 IP访问的寻呼消息传输通道与核心网的寻呼消息传输通道不同。也可以 通过标识方式让家用基站网关区分寻呼消息是核心网触发的还是本地 IP触 发的。 当存在家用基站网关的情况下， 如果通过隧道方式区分寻呼消息， 则移 动性管理实体在判断下行数据为本地 IP的数据后，可以将寻呼消息在预先约 定的传输通道上传送； 在判断为本地 IP访问的寻呼消息 （通过本地 IP访问 的寻呼消息传输通道传送）后， 家用基站网关向该终端本地 IP访问所对应的 基站或家用基站或数据分流功能实体（均可以与本地网关地址相同）发送寻 呼消息。 当存在家用基站网关的情况下， 如果通过标识方式区分寻呼消息， 则移 动性管理实体判断下行数据为本地 IP的数据后， 在寻呼消息中添加本地 IP 访问标识， 家用基站网关根据寻呼消息中的本地 IP访问标识判断为本地 IP 的数据触发后，向该终端本地 IP访问所对应的基站或家用基站或数据分流功 能实体（均可以与本地网关地址相同）发送寻呼消息。 如果家用基站网关判断寻呼消息不是本地 IP访问触发的，而是由核心网 发起的， 则家用基站网关可能向该家用基站网关下连接的所有基站、 家用基 站和数据分流功能实体或者允许终端接入的基站、 家用基站和数据分流功能 实体发送该寻呼消息。 The preferred embodiment of the present invention is that the mobility management entity initiates the operation of the paging terminal only to the radio side network element of the local IP access after receiving the downlink data notification triggered by the local IP access. The mobility management entity can be MME (Mobility Management Entity, Mobile Management Unit), MSC (Mobile Switching Centre) or SGSN (Serving GPRS) Support Node, service GPRS support node). The wireless side network element may be a base station, a home base station, an RNC (Radio Network Controller), a home base station gateway, and a data offload function entity. The wireless side network element can be combined with the local gateway. Preferably, the mobility management entity determines whether the received downlink data notification is triggered by the local IP access by using one of the following methods: determining whether the network element that initiates the downlink data notification is a wireless side network element or a local gateway (can be performed by using a source address) Judging); determining whether there is a local IP indication in the downlink data notification (the indication may be added by the local gateway or the wireless side network element). Specifically, for the first mode: if the mobility management entity finds that the downlink data notification is initiated by the local gateway or the wireless side network element, it determines that the downlink data is downlink data triggered by the local IP access. For the second mode: If the mobility management entity finds that the downlink data notification message includes the local IP indication, that is, the downlink data is the downlink data triggered by the local IP access, the downlink data is determined to be the downlink data triggered by the local IP access. The wireless side network element of the local IP access can be the same as the local gateway address, and the wireless side network element accessed by the local IP is combined with the local gateway. When there is a home base station gateway, it can be tunneled to distinguish whether the paging message is triggered by the core network or triggered by the local IP, that is, the paging message transmission of the local IP access between the mobility management entity and the home base station gateway. The channel is different from the paging message transmission channel of the core network. The home base station gateway can also distinguish whether the paging message is triggered by the core network or triggered by the local IP. If there is a home base station gateway, if the paging message is distinguished by tunneling, the mobility management entity may transmit the paging message on the pre-agreed transmission channel after determining that the downlink data is the data of the local IP; After the paging message for the local IP access (transmitted through the paging message transmission channel accessed by the local IP), the home base station gateway accesses the corresponding base station or the home base station or the data offloading function entity to the local IP address of the terminal (both can be connected to the local gateway) The address is the same) Send a paging message. If there is a home base station gateway, if the paging message is distinguished by the identification manner, the mobility management entity determines that the downlink data is the data of the local IP, adds the local IP access identifier to the paging message, and the home base station gateway according to the paging. The local IP access identifier in the message is judged to be the local IP address. After the data is triggered, the paging message is sent to the base station or the home base station or the data offloading function entity (both of which can be the same as the local gateway address) corresponding to the local IP access of the terminal.

FIG. 5 is a flowchart of the present invention, based on the home base station system of FIG. 1, providing a procedure for a home base station system to initiate a paging procedure for an idle user when data is accessed from a local IP. The specific steps are as follows: Step 501: After receiving the data sent to the terminal, the local gateway will cache the data. Step 502: The local gateway sends a downlink data notification message to the mobility management entity. Step 503: The mobility management entity replies to the downlink. Step 504: The mobility management entity finds that the downlink data notification message is initiated by the local gateway or the home base station gateway, and determines that the downlink data is data triggered by local IP access, and only pages the home base station accessed by the local IP; The method for determining the IP data may also be based on the local IP indication in the downlink data notification message.

图 6是本发明在图 2a家用基站系统的基础上， 提供的在数据从本地 IP 接入时， 家用基站系统对空闲用户发起寻呼过程的流程图。 具体步骤描述如 下： 步骤 601 , 在收到发往终端的数据后， 本地网关将緩存该数据； 步骤 602 , 本地网关向家用基站网关发送下行数据通知消息； 步骤 603 , 家用基站网关将该下行数据通知消息转发至移动性管理实体； 步骤 604, 移动性管理实体回复下行数据通知响应； 步骤 605, 家用基站网关转发下行数据通知响应给本地网关； 步骤 606, 移动性管理实体发现下行数据通知消息为本地网关或家用基 站网关发起， 则判断为本地 IP的数据， 仅寻呼本地 IP访问的家用基站； 步骤 605和 606顺序可互换。 对本地 IP数据的判断方法还可以是根据下行数据通知消息中的本地 IP 指示。 如果移动性管理实体发现下行数据通知消息中包括了下行数据为本地 IP访问触发的下行数据的本地 IP指示， 则可判断为本地 IP访问触发的下行 数据。 步骤 607, 判断下行数据为本地 IP访问触发的数据后， 移动性管理实体 不会向终端跟踪区内的所有基站发送寻呼消息， 而只向家用基站网关发送寻 呼， 携带终端标识； 可以通过隧道方式让家用基站网关区分寻呼消息是核心网触发的还是本 地 IP触发的， 即在移动性管理实体和家用基站网关之间， 对本地 IP访问的 寻呼消息传输通道与核心网的寻呼消息传输通道不同。 在该方式下， 移动性 管理实体在判断下行数据为本地 IP访问触发的数据后，可以将寻呼消息在预 先约定的传输通道上传送； 或者， 也可以通过标识方式让家用基站网关区分寻呼消息是核心网触发 的还是本地 IP触发的。在该方式下，移动性管理实体判断下行数据为本地 IP 访问触发的数据后， 可以在寻呼消息中添加本地 IP访问标识； 步骤 608, 家用基站网关向本地 IP访问的家用基站（本实施例中家用基 站地址与本地网关地址相同）发送寻呼消息， 携带终端标识； 如果通过隧道方式区分寻呼消息是核心网触发的还是本地 IP触发的，则 在判断为本地 IP访问的寻呼消息 （通过本地 IP访问的寻呼消息传输通道传 送）后， 家用基站网关向该终端本地 IP访问所对应的家用基站（可以与本地 网关地址相同）发送寻呼消息。 如果通过标识方式让家用基站网关区分寻呼消息是核心网触发的还是本 地 IP触发的， 则家用基站网关根据寻呼消息中的本地 IP访问标识判断为本 地 IP的数据触发后， 向该终端本地 IP访问所对应的家用基站 （可以与本地 网关地址相同）发送寻呼消息。 步骤 609, 接收到寻呼消息后， 家用基站将对终端进行寻呼； 步骤 610, —旦获取到寻呼信息， 终端将执行服务请求过程。 FIG. 6 is a flowchart of the present invention, based on the home base station system of FIG. 2a, providing a procedure for a home base station system to initiate a paging procedure for an idle user when data is accessed from a local IP. The specific steps are as follows: Step 601: After receiving the data sent to the terminal, the local gateway caches the data. Step 602: The local gateway sends a downlink data notification message to the home base station gateway. Step 603: The home base station gateway uses the downlink data. The notification message is forwarded to the mobility management entity. Step 604: The mobility management entity replies to the downlink data notification response. Step 605: The home base station gateway forwards the downlink data notification response to the local gateway. Step 606: The mobility management entity finds that the downlink data notification message is When the local gateway or the home base station gateway initiates, it is determined to be the data of the local IP, and only the home base station accessed by the local IP is paged; steps 605 and 606 are sequentially interchangeable. The method for determining the local IP data may also be based on the local IP indication in the downlink data notification message. If the mobility management entity finds that the downlink data notification includes the local IP indication of the downlink data triggered by the local IP access, the downlink data may be determined as the downlink data triggered by the local IP access. Step 607: After determining that the downlink data is data triggered by the local IP access, the mobility management entity does not send a paging message to all base stations in the tracking area of the terminal, but only sends a paging to the home base station gateway, and carries the terminal identifier; The tunnel mode allows the home base station gateway to distinguish whether the paging message is triggered by the core network or the local IP, that is, between the mobility management entity and the home base station gateway, paging the paging message transmission channel and the core network for the local IP access. The message transmission channel is different. In this mode, after determining that the downlink data is the data triggered by the local IP access, the mobility management entity may transmit the paging message on the pre-agreed transmission channel; or, the home base station gateway may distinguish the paging by using the identifier manner. The message is triggered by the core network It is also triggered by local IP. In this mode, after the mobility management entity determines that the downlink data is the data triggered by the local IP access, the local IP access identifier may be added to the paging message. Step 608: The home base station gateway accesses the home base station to the local IP address. The home base station address is the same as the local gateway address. The paging message is sent to carry the terminal identifier. If the paging message is triggered by the core network or triggered by the local IP, the paging message determined to be the local IP access is After being transmitted by the paging message transmission channel of the local IP access, the home base station gateway sends a paging message to the home base station corresponding to the local IP access of the terminal (which can be the same as the local gateway address). If the home base station gateway distinguishes whether the paging message is triggered by the core network or the local IP, the home base station gateway determines that the data of the local IP is triggered according to the local IP access identifier in the paging message, and then localizes to the terminal. The home base station corresponding to the IP access (which can be the same as the local gateway address) sends a paging message. Step 609, after receiving the paging message, the home base station will page the terminal; Step 610, once the paging information is obtained, the terminal will perform the service request process.
