接入网选择方法、用户设备、 ***和选网策略单元技术领域 Access network selection method, user equipment, system, and network selection policy unit

本发明涉及通信领域中蜂窝网和无线接入网技术，具体地，涉及一种接入网选择方法、用户设备、 ***和选网策略单元。 The present invention relates to a cellular network and a radio access network technology in the field of communications, and in particular to an access network selection method, a user equipment, a system, and a network selection policy unit.

背景技术 Background technique

随着 WLAN热点的大量部署，同一区域可能被多个 WLAN接入点和蜂窝基站共同覆盖，根据用户的需求和网络的使用情况来为用户进行合理网络选择变得越来越重要。目前，现网的使用及现有的选网技术方案存在如下缺陷： With the large deployment of WLAN hotspots, the same area may be covered by multiple WLAN access points and cellular base stations. It is more and more important to make reasonable network selection for users according to user needs and network usage. At present, the use of the existing network and the existing network selection technology solutions have the following drawbacks:

1 ) UE (User Equipment, 用户设备）扫描 WLAN (Wireless Local Area Networks, 无线局域网络）的 AP (Access Point, 接入点）信息，由用户根据可用的 SSID (Service Set Identifier, 服务集标识）选择 WLAN接入，需要用户参与复杂的操作，影响了用户的体验。 The user equipment (User Equipment) scans the AP (Access Point) information of the WLAN (Wireless Local Area Networks). The user selects the available SSID (Service Set Identifier). WLAN access requires users to participate in complex operations and affects the user experience.

2)选网策略的静态性，导致网络使用的不均衡；不论是终端静态配置还是网络提供的策略都未考虑 WLAN和蜂窝网的实际使用情况；例如，即使当前 WLAN已经拥塞，也无法进行相应的策略调整。 2) The staticity of the network selection strategy leads to the imbalance of network usage; neither the static configuration of the terminal nor the policy provided by the network considers the actual usage of the WLAN and the cellular network; for example, even if the current WLAN is already congested, it cannot be correspondingly Strategy adjustment.

3) 网络缺少相应的信息，目前终端上报的接入网信息的信息量不足，例如，附近 WLAN的 SSID; 选网策略单元缺少和其它网元交换信息的机制，无法根据终端侧的信息和网络侧的网络使用情况信息来进行网络的选择。 3) The network lacks corresponding information. Currently, the information of the access network information reported by the terminal is insufficient, for example, the SSID of the nearby WLAN; the network selection policy unit lacks the mechanism for exchanging information with other network elements, and cannot be based on the information and network of the terminal side. The network usage information on the side is used to select the network.

4) 缺少准确的 WLAN分布和蜂窝网接入的对应方法，一个蜂窝网小区覆盖下，可能有多个、属于不同拥有者的 WLAN接入，使得网络难以仅从终端上报的地理位置信息获知其终端的实际网络信号状态。 4) The lack of accurate WLAN distribution and the corresponding method of cellular network access, under the coverage of a cellular network, there may be multiple WLAN accesses belonging to different owners, making it difficult for the network to learn only the geographical location information reported by the terminal. The actual network signal status of the terminal.

要实现选网的优化，要解决的关键问题是网络侧的选网策略单元如何能够准确获知 UE所处的网络环境，包括 UE当前所在的蜂窝网络和所在的其它非 3GPP接入网（如 WLAN、 WiMAX等）的可用情况，各接入点的信号强度等。 To realize the optimization of the network selection, the key problem to be solved is how the network selection policy unit on the network side can accurately know the network environment in which the UE is located, including the cellular network where the UE is currently located and other non-3GPP access networks (such as WLAN) in which the UE is located. , WiMAX, etc., the signal strength of each access point.

申请号为 200910090433.X 的中国发明专利申请提出了一种 UE 通过 WLAN 接入网接入到核心网的方法。 UE首先接入 EPC (分组核心网），与择功能）进行交互（携带自身的位置信息和能力信息）， ANDSF返回 WLAN 接入网信息（WLAN接入网可接入的无线核心网信息以及 UE当前位置存在的 WLAN网络）给 UE，然后 UE建立与 WLAN接入网的连接；进行认证时， WLAN接入网发送 EAP (可扩展验证协议)请求给 UE， UE根据获得的 WLAN 接入网信息及自身的接入能力，选择一个无线核心网并将相应的身份携带在 EAP回复消息中返回给 WLAN接入网。 The Chinese invention patent application with the application number 200910090433.X proposes a method for the UE to access the core network through the WLAN access network. The UE first accesses the EPC (Packet Core Network), with Select function) to interact (bring its own location information and capability information), and the ANDSF returns the WLAN access network information (the wireless core network information accessible by the WLAN access network and the WLAN network where the current location of the UE exists) to the UE, and then the UE Establishing a connection with the WLAN access network; when performing authentication, the WLAN access network sends an EAP (Extensible Authentication Protocol) request to the UE, and the UE selects a wireless core network according to the obtained WLAN access network information and its access capability. The corresponding identity is carried in the EAP reply message and returned to the WLAN access network.

申请号为 200910179815.X 的中国发明专利申请公开了一种接入网信息获取方法。终端向 ANDSF发送接入网络请求， ANDSF从 AAA (鉴权授权计费服务器）获取接入网属性信息，并根据终端的能力（支持的协议类型、是否需要接入信任的接入网）及接入网属性信息（接入网支持的协议、接入网的信任关系）选择出一个或多个接入网并将接入网信息发送给终端，终端根据接收到的接入网信息选择接入网并进行接入。 The Chinese invention patent application with the application number 200910179815.X discloses a method for obtaining access network information. The terminal sends an access network request to the ANDSF, and the ANDSF obtains the access network attribute information from the AAA (Authentication Authorization Accounting Server), and according to the capability of the terminal (the supported protocol type, whether access to the trusted access network is required) The network access attribute information (the protocol supported by the access network and the trust relationship of the access network) selects one or more access networks and sends the access network information to the terminal, and the terminal selects the access according to the received access network information. Network and access.

申请号为 201010117475.0的中国发明专利申请提到了一种终端接入 AP 的选择方法。通过无线接入控制器 AC收集其控制的多个 AP上报的同一 UE 的信息（包括信息强度、噪度、发送功率），针对某个特定 UE，为其重新选择 AP，并为该 AP动态分配专用 MAC (Media Access Control, 介质访问控制）地址，用于与 UE之间进行通信。 The Chinese invention patent application with application number 201010117475.0 refers to a method for selecting a terminal to access an AP. The information of the same UE (including information strength, noise, and transmission power) reported by multiple APs controlled by the AP is collected by the radio access controller AC, and the AP is reselected for a specific UE and dynamically allocated for the AP. A dedicated MAC (Media Access Control) address used to communicate with the UE.

在实现本发明过程中，发明人发现现有技术中至少存在如下问题：以现有的 ANDSF方案为例， UE会在向 ANDSF的请求信息中携带自己的位置信息以及偏好的接入网类型等信息，目前 UE能提供位置信息的粒度为蜂窝小区的 ID (CelUd), ANDSF根据 UE提供的位置信息找到 UE附近可用的接入网信息，在 ANDSF中存在一个数据库给出了蜂窝网络和非 3GPP 接入网（如 WLAN) 间的映射关系，如表 1所示： In the process of implementing the present invention, the inventor has found that at least the following problems exist in the prior art: Taking the existing ANDSF scheme as an example, the UE carries its own location information and a preferred access network type in the request information to the ANDSF. Information, the granularity at which the UE can provide the location information is the cell ID (CelUd), and the ANDSF finds the access network information available in the vicinity of the UE according to the location information provided by the UE. There is a database in the ANDSF that gives the cellular network and the non-3GPP. The mapping relationship between access networks (such as WLAN) is shown in Table 1:

表 1 UE所在的 3GPP小区 ID 接入类型为 WLAN Table 1 The 3GPP cell ID access type where the UE is located is WLAN.

位置 1 SSID =WiFi1, BSSID = BS1 Location 1 SSID = WiFi1, BSSID = BS1

Cell— Id = Cell— 1 SSID =WiFi2, BSSID = BS2 Cell— Id = Cell— 1 SSID = WiFi2, BSSID = BS2

SSID =WiFi3, BSSID = BS3 SSID = WiFi3, BSSID = BS3

SSID =WiFi4, BSSID = BS4 SSID = WiFi4, BSSID = BS4

位置 2 N/A Location 2 N/A

Cell Id = Cell 2 Cell Id = Cell 2

位置 n SSID =WiFi5, BSSID = BS5 Location n SSID = WiFi5, BSSID = BS5

Cell— Id = Cell— n SSID =WiFi6, BSSID = BS6 Cell— Id = Cell— n SSID = WiFi6, BSSID = BS6

SSID =WiFi7, BSSID = BS7 SSID = WiFi7, BSSID = BS7

SSID =WiFi8, BSSID = BS8 SSID = WiFi8, BSSID = BS8

但是由于蜂窝网和非 3GPP接入网（如 WLAN) 的覆盖范围差异较大，部署情况复杂，上述映射关系只体现了一种粗略的部署关系，而不能体现出 UE当前所在位置下具体有哪些 WLAN接入网以及各个 WLAN接入网的信号强度，从而不能有针对性的向 UE提供网络选择策略。 However, because the coverage of the cellular network and the non-3GPP access network (such as WLAN) is different, the deployment situation is complicated. The above mapping relationship only reflects a rough deployment relationship, but does not reflect the specific location of the current location of the UE. The signal strength of the WLAN access network and each WLAN access network, so that the network selection policy cannot be provided to the UE in a targeted manner.

上述申请号为 200910090433.X的专利申请， UE与 ANDSF之间进行交互的信息只包括 UE的位置和能力信息， ANDSF向 UE提供 WLAN接入网可接入的无线核心网信息以及 UE当前位置存在的 WLAN网络， UE仅根据这些信息来选择合适的接入网，未考虑接入网负载情况，可能会造成某些 AP 负载过重，影响网络整体性能。 In the above patent application No. 200910090433.X, the information exchanged between the UE and the ANDSF includes only the location and capability information of the UE, and the ANDSF provides the UE with the wireless core network information accessible by the WLAN access network and the current location of the UE. The WLAN network, the UE only selects the appropriate access network based on the information, and does not consider the load of the access network, which may cause some APs to be overloaded and affect the overall performance of the network.

上述申请号为 200910179815.X的专利申请，可以解决切换前 UE无法获取接入网的属性信息而影响终端切换效率和业务连续性的问题，而该方案 UE 能够获得的接入网属性信息包括接入网支持的协议、接入网的信任关系等，但未考虑接入网的负载情况。 The above patent application No. 200910179815.X can solve the problem that the UE cannot obtain the attribute information of the access network before the handover and affects the handover efficiency and service continuity of the terminal, and the access network attribute information that the UE can obtain includes The protocol supported by the network access, the trust relationship of the access network, etc., but the load of the access network is not considered.

上述申请号为 201010117475.0的专利申请，该方案与现有技术相比，通过终端扫描 AP自行决定接入哪个 AP的方案，增强了网络侧 AC对于 UE选择接入 AP的控制力度，可实现一定程度上的 AP负载均衡，但该方案只有当 UE在同一 AC控制下的各个 AP间进行移动时有效，不能实现多 AC控制下的 AP间负载均衡。 The application of the above-mentioned application number is 201010117475.0. Compared with the prior art, the scheme of the AP is determined by the terminal scanning AP, and the control of the AP on the AP to access the AP is enhanced. The AP load balancing is effective, but the solution is effective only when the UE moves between APs under the same AC control, and load balancing between APs under multiple AC control cannot be implemented.
