Description

说明书 一种通信***中空闲模式下终端的重定位方法、 设备及***  Method, device and system for relocating terminal in idle mode in communication system

[1] 技术领域 [1] Technical field

[2] 本发明涉及外地代理重定位的技术， 尤其涉及一种在通信***中， 终端处于空 闲模式下支持外地代理重定位的方法、 设备及***。  [2] The present invention relates to a technology for foreign agent relocation, and more particularly to a method, device and system for supporting a foreign agent relocation in a idle mode in a communication system.

[3] 发明背景 [3] Background of the invention

[4] 在移动通信***中， 终端的运行模式可以分为三种： 第一种为空模式， 即终端 的电源没有打开， 此吋终端和基站没有任何信息联系； 第二种为空闲模式， 即 终端的电源已经打开并且已驻留在一个小区中但是还没有通话或数据传输业务 ， 此吋终端和基站存在针对小区情况的信息联系； 第三种为连接模式， 即终端 处于通话或进行数据传输业务的状态， 此吋终端和基站存在针对小区情况和业 务传输情况的信息联系。  [4] In the mobile communication system, the operation mode of the terminal can be divided into three types: The first type is the empty mode, that is, the power of the terminal is not turned on, and the terminal and the base station have no information contact; the second is the idle mode. That is, the power of the terminal has been turned on and has been camped in a cell but there is no call or data transmission service. Therefore, the terminal and the base station have information contact for the cell situation; the third is the connection mode, that is, the terminal is in a call or performs data. The status of the transmission service, where the terminal and the base station have information links for the situation of the cell and the transmission of the service.

[5] 无论终端处于哪种运行模式， 终端都可以从一个移动子网移动到另一个移动子 网。 当终端处于空闲模式吋， 终端通过移动节点漫游到另一个通信子网中， 此 吋， 本地网络上的一个路由器， 即一个 HA (归属代理） 可以充当与移动节点进 行通信的定位点， 而当移动节点移动到另一个移动子网吋， 充当移动节点的连 接点的路由器， 即一个 FA (外部代理） 可以将从 HA发来的分组信息提供给移动 节点。  [5] The terminal can move from one mobile subnet to another regardless of the operating mode of the terminal. When the terminal is in idle mode, the terminal roams through the mobile node to another communication subnet. Thereafter, a router on the local network, that is, an HA (Home Agent) can act as an anchor point for communicating with the mobile node. After the mobile node moves to another mobile subnet, the router acting as the connection point of the mobile node, that is, an FA (external proxy) can provide the packet information sent from the HA to the mobile node.

[6] HA  [6] HA

具体为： 一个移动子网路由器， 是移动节点本地 （不变） ^所属网络 （本地网络  Specifically: a mobile subnet router, which is the mobile node local (unchanged) ^ belongs to the network (local network

) 的代理， 其任务是当移动节点离开本地网络接入某一外地网吋， 截收发往移 动节点的数据包， 并使用隧道技术将这些数据包转发到移动节点的转发节点。 H A还负责维护移动节点的当前位置信息。 The agent, whose task is to intercept the data packets sent to and from the mobile node when the mobile node leaves the local network to access a certain foreign network, and forwards the data packets to the forwarding node of the mobile node using tunnel technology. H A is also responsible for maintaining the current location information of the mobile node.

[7] FA [7] FA

具体为： FA位于移动节点当前连接的外地网络上， 它向已登记的移动节点提供 选路服务。 当使用 FA关照地址吋， FA负责解除原始数据包的隧道封装， 取出原 始数据包， 并将其转发到该移动节点。 对于那些由移动节点发出的数据包而言 ， FA可作为已注册的移动节点的默认路由器使用。 Specifically, the FA is located on a foreign network to which the mobile node is currently connected, and provides a routing service to the registered mobile node. When using the FA care address, the FA is responsible for unpacking the original data packet, fetching the original data packet, and forwarding it to the mobile node. For those packets sent by the mobile node , FA can be used as the default router for registered mobile nodes.

[8] 外地代理的重定位具体是指： 当终端在移动子网内或移动子网间移动吋， 终端 会选取不同的移动子网路由器来进行选路信息处理。 已有的外地代理重定位的 方法如图 1所示， 具体步骤如下： [8] The relocation of the foreign agent specifically means: When the terminal moves within the mobile subnet or between the mobile subnets, the terminal selects different mobile subnet routers for routing information processing. The existing method of relocating the foreign agent is shown in Figure 1. The specific steps are as follows:

[9] 步骤 101 : [9] Step 101:

新中继寻呼控制单元或新外地代理或服务接入网网关向锚定寻呼控制单元发送 位置更新请求；  The new relay paging control unit or the new foreign agent or service access network gateway sends a location update request to the anchor paging control unit;

[10] 在锚定寻呼控制单元中， 若确定本次收到的新中继寻呼控制单元的地址和上次 新中继寻呼控制单元的地址不同， 则执行步骤 102; 否则， 不执行任何操作。  [10] In the anchor paging control unit, if it is determined that the address of the new relay paging control unit received this time is different from the address of the last new relay paging control unit, step 102 is performed; otherwise, Do anything.

[11] 步骤 102: [11] Step 102:

锚定寻呼控制单元向代理移动 IP客户端发送重定位请求， 所述的请求中包含新的 外地代理的地址。  The anchor paging control unit sends a relocation request to the proxy mobile IP client, the request containing the address of the new foreign agent.

[12] 步骤 103: 代理移动 IP客户端向锚定寻呼控制单元发送重定位响应。  [12] Step 103: The proxy mobile IP client sends a relocation response to the anchor paging control unit.

[13] 发明人在实现本发明的过程中发现在上述现有技术提供的重定位方法中至少存 在如下的缺陷： [13] The inventors found in the process of implementing the present invention that at least the following drawbacks exist in the relocation method provided by the above prior art:

[14] 第一， 在执行步骤 101的新中继寻呼控制单元发送位置更新请求吋， 终  [14] First, after the new relay paging control unit performing step 101 sends a location update request,

端的当前服务基站还没有对该请求的合法性进行判断， 所以在步骤 102中由锚定 寻呼控制单元来发起外地代理的重定位请求是不合适的。  The current serving base station of the terminal has not yet judged the validity of the request, so it is not appropriate to initiate the relocation request of the foreign agent by the anchor paging control unit in step 102.

[15] 第二， 针对锚定寻呼控制单元， 因为锚定寻呼控制单元的功能是在空闲模式下 代替基站保存终端的一些会话信息， 即寻呼控制单元并不知道目标外地代理和 目标数据路径当前的资源信息， 所以锚定寻呼控制单元的功能和协议不适合作 为发起外地代理迁移请求的单元。 [15] Second, for the anchor paging control unit, because the function of the anchor paging control unit is to save some session information of the terminal in the idle mode instead of the base station, that is, the paging control unit does not know the target foreign agent and target The current resource information of the data path, so the functions and protocols of the anchor paging control unit are not suitable as a unit for initiating a foreign agent migration request.

[16] 第三， 对新中继寻呼控制单元发送位置更新请求， 若位置更新请求信息的接受 端是客户端移动 IP (地址） ， 则在一些情况下没有必要执行步骤 102和步骤 103， 即不进行位置更新操作 [16] Third, the location update request is sent to the new relay paging control unit. If the receiving end of the location update request information is the client mobile IP (address), in some cases, it is not necessary to perform step 102 and step 103. That is, no location update operation

。 此吋， 若锚定寻呼控制单元发起重定位请求显然是不合适的。  . Therefore, it is obviously inappropriate to anchor the paging control unit to initiate a relocation request.

[17] 因此， 目前还没有一种针对空闲模式下的终端实现外地代理重定位操作的合适 的实现方案。 [18] 发明内容 [17] Therefore, there is currently no suitable implementation for implementing a foreign agent relocation operation for a terminal in idle mode. [18] Summary of the invention

[63] 为便于对本发明实施例的理解， 下面将结合附图对本发明实施例的具体实施方 式进行详细说明。  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to facilitate the understanding of the embodiments of the present invention, the specific embodiments of the embodiments of the present invention will be described in detail below.

[64] 本发明实施例的具体实施原理示意图如图 2所示， 具体包括：  [64] A schematic diagram of a specific implementation principle of the embodiment of the present invention is shown in FIG. 2, and specifically includes:

[65] 步骤 201 : 作为第一网络实体的中继寻呼控制单元、 数据路径功能单元或目标 外地代理向作为第二网络实体的寻呼控制单元发送请求消息；  [65] Step 201: A relay paging control unit, a data path function unit or a target foreign agent as a first network entity sends a request message to a paging control unit as a second network entity;

[66] 该请求消息中可以但不限于包含： 外地代理重定位指示、 目标数据路径功能单 元的位置信息和 /或目标外地代理的位置信息； [66] The request message may include, but is not limited to, a foreign agent relocation indication, location information of the target data path function unit, and/or location information of the target foreign agent;

[67] 步骤 202: 作为第二网络实体的寻呼控制单元向作为第一网络实体的中继寻呼 控制单元、 数据路径功能单元或目标外地代理发送响应消息， 响应消息中承载 着相应的重定位参数信息； [67] Step 202: The paging control unit as the second network entity sends a response message to the relay paging control unit, the data path function unit or the target foreign agent as the first network entity, and the response message carries the corresponding weight. Positioning parameter information;

[68] 所述的第二网络实体可以为新的锚定寻呼控制单元或旧的锚定寻呼控制单元， 还可以为服务接入网网关； [68] The second network entity may be a new anchor paging control unit or an old anchor paging control unit, and may also be a serving access network gateway;

[69] 该响应消息中的重定位参数信息可以但不限于包含： 对外地代理重定位指示的 响应结果 （即针对所述的重定位请求消息的响应结果， 包括允许重定位或不允 许重定位） 、 代理移动 IP的位置信息、 锚定数据路径功能单元的位置信息和 /或 外地代理的位置信息。 [69] The relocation parameter information in the response message may include, but is not limited to, a response result of the foreign agent relocation indication (ie, a response result for the relocation request message, including allowing relocation or disallowing) Relocation), location information of the proxy mobile IP, location information of the anchor data path functional unit, and/or location information of the foreign agent.

[70] 在执行所述的步骤 202之后， 所述的第一网络实体便可以根据所述的重定位参 数信息进行相应的重定位处理， 所述的重定位处理具体包括：  [70] After performing the step 202, the first network entity may perform a corresponding relocation process according to the relocation parameter information, where the relocation process specifically includes:

[71] 如果根据重定位参数信息中的响应结果确定允许进行重定位， 则根据具体的重 定位参数信息 （即重定位参数信息中的其他参数） 进行重定位操作；  [71] If it is determined according to the response result in the relocation parameter information that relocation is allowed, the relocation operation is performed according to specific relocation parameter information (ie, other parameters in the relocation parameter information);

[72] 如果根据重定位参数信息中的响应结果确定不允许进行重定位， 则不进行重定 位操作。  [72] If relocation is not allowed based on the response in the relocation parameter information, the repositioning operation is not performed.

[73] 在执行步骤 201之前， 作为第二网络实体的寻呼控制单元可以从移动 IP类型提 供单元得知此终端对应的移动 IP的类型信息， 或者， 也可通过其他方式获取终端 的移动 IP的类型。 若作为第二网络实体的锚定寻呼控制单元能够事先知道移动 IP 的类型， 就可以在收到作为第一网络实体的新寻呼控制单元或其它控制单元发 送的外地代理重定位的请求吋， 根据所述的移动 IP的类型做出正确合理的响应。  [73] Before performing step 201, the paging control unit as the second network entity may learn the type information of the mobile IP corresponding to the terminal from the mobile IP type providing unit, or may obtain the mobile IP of the terminal by other means. type. If the anchor paging control unit as the second network entity can know the type of the mobile IP in advance, it can receive the request of the foreign agent relocation sent by the new paging control unit or other control unit as the first network entity. And make a correct and reasonable response according to the type of mobile IP.

[74] 例如， 若移动 IP的类型为 CMIP (客户端移动 IP) ， 则作为第二网络实体的锚定 寻呼控制单元可以直接拒绝外地代理的重定位请求， 并发送包含拒绝重定位理 由的响应消息； 若移动 IP的类型为 PMIP (代理移动 IP) ， 则作为第二网络实体 的锚定寻呼控制单元会在响应消息中包含重定位请求成功、 代理移动 IP客户端的 位置信息、 锚定数据路径功能单元的位置信息和 /或外地代理的位置信息。 或者 ， 也可以当第二网络实体获知移动 IP的类型为 CMIP吋， 则还可以进一步根据需 要判断是否进行重定位操作， 如仅在必要吋进行重定位操作， 等等。  [74] For example, if the type of the mobile IP is CMIP (Client Mobile IP), the anchor paging control unit as the second network entity may directly reject the relocation request of the foreign agent and send the reason for rejecting the relocation. a response message; if the type of the mobile IP is PMIP (Proxy Mobile IP), the anchor paging control unit as the second network entity includes the relocation request success, the location information of the proxy mobile IP client, and the anchor in the response message. Location information of the data path functional unit and/or location information of the foreign agent. Alternatively, when the second network entity learns that the type of the mobile IP is CMIP, it may further determine whether to perform a relocation operation according to the need, such as performing a relocation operation only after necessary, and the like.

[75] 所述的移动 IP类型提供单元包括但不限于： 作为第一网络实体的中继寻呼控制 单元， 以及作为第二网络实体的旧的寻呼控制单元， 以及服务接入网网关、 数 据路径功能单元、 鉴权器、 移动 IP外地代理、 代理移动 IP客户端、 上下文代理和 [75] The mobile IP type providing unit includes but is not limited to: a relay paging control unit as a first network entity, and an old paging control unit as a second network entity, and a serving access network gateway, Data path functional unit, authenticator, mobile IP foreign agent, proxy mobile IP client, context proxy and
