摘要： Disclosed herein is a method useful for target user equipment (UE) sending a location report. When the target UE is located in a first central network (CN) of a location service (LCS) system, the target UE reports the location report to the LCS system. If the target UE does not receive a location report response from the LCS system, when being located in a second CN of LCS system, target UE will continue to report the location report to LCS system. In accordance with one aspect of the disclosed method, the waste of location service system resource is avoided as well as the execution efficiency of location service is increased. In addition, during procedure of change of area event location request, the consequent processing of request thereof is guaranteed to be normal, so that execution efficiency of location service is increased. Moreover, message interaction between the function entities is saved for the exception cases. Accordingly, the waste of public land mobile communication network resource caused by generation of excessive useless messages is avoided.

摘要： The present invention provides a method for reducing the load on Home Subscriber Server (HSS)'s interface. After receiving a request message from Serving Call Session Control Function (S-CSCF) comprising the request for storing the name of the S-CSCF and for downloading the user's subscription information, HSS first stores the name of S-CSCF in the request message, then returns to the S-CSCF a response message comprising the user's subscription information. This invention simplifies the steps of inquiring about the user's subscription information, optimizes the service procedure, and reduces the load on HSS's interface. In addition, when receiving the inquiry message from I-CSCF, HSS returns directly to I-CSCF response message comprising the S-CSCF name and the S-CSCF capability information set that has the capability to meet the most strict service subscription requirement of the UE, further reducing the load on HSS's interface. This invention has no impact on the existing network architecture and services, nor is it needed to modify the existing interface specifications, thus being highly compatible and extendable.

摘要翻译： 本发明提供一种降低归属用户服务器（HSS）接口负载的方法。 在收到包含存储S-CSCF名称的请求的服务呼叫会话控制功能（S-CSCF）的请求消息和下载用户的订阅信息之后，HSS先将S-CSCF的名称存储在请求消息中， 然后向S-CSCF返回包含用户订阅信息的响应消息。 本发明简化了查询用户订阅信息，优化业务流程，降低了HSS接口负载的步骤。 另外，当从I-CSCF接收到查询消息时，HSS直接返回到包含S-CSCF名称和S-CSCF能力信息集的I-CSCF响应消息，该消息具有满足最严格的业务订阅要求的能力 UE进一步降低了HSS接口的负载。 本发明对现有的网络架构和服务没有影响，也不需要修改现有的接口规范，从而具有高度兼容性和可扩展性。

摘要： The present invention discloses an interactive method for determining network selection information of user terminal in wireless local area network (WLAN). In the present invention, a user terminal covered by more than one WLAN inquires each detected WLAN successively in turn using preset initial network selection information. If the current WLAN access network is directly connected with the initially selected network of the user terminal, the initially selected network of the user terminal is determined to be the network to be accessed. If the current WLAN access network is not directly connected with the initially selected network of the user terminal, the next WLAN is inquired, and so on, until a WLAN access network directly connected with the initially selected network of the user terminal is found. If all the WLAN access networks have been inquired and there is no WLAN access network that is directly connected with the initially selected network of the user terminal, the process ends, or the user terminal can select an appropriate network to access from among all of the visited networks. The invention can allow a user terminal covered by more than one WLAN to select an appropriate wireless communication network to access.

摘要： The present invention is an interactive processing method for selecting network information for a user terminal in a WLAN. After a radio connection between a WLAN user terminal and a WLAN AN is established, the WLAN AN or the WLAN user terminal initiates an authentication procedure, and the WLAN AN sends to the WLAN user terminal a user identity request message. After receiving the user identity request message, the WLAN user terminal returns to the WLAN AN a message containing network selection information, judges whether the network selection information in the received message identifies a wireless communication network connected with the WLAN, and, if yes, sends the authentication request of the WLAN user terminal to the wireless communication network identified by the network selection information. Otherwise, the network sends an advisement message to the WLAN user terminal, and the WLAN user terminal performs subsequent operations according to the contents of the advisement. This invention enables a WLAN user terminal to select an appropriate wireless communication network according to its need when the WLAN user terminal accesses a network via a WLAN connected with a plurality of wireless communication networks.
