摘要： The present invention discloses a method for implementing communications between multiple subnets covered by one physical Mobile Switching Center (MSC), the method includes the steps of: mapping one physical MSC to multiple logical MSCs, i.e. multiple virtual MSCs, and assigning a virtual MSC number to each virtual MSC, and setting relationship(s) between location area(s) covered by the virtual MSC and the virtual MSC number of each virtual MSC; transmitting location information of a terminal with the virtual MSC number during communications to implement communications among multiple subnets. During communication, since the terminal location is transmitted according to the virtual MSC number, it is possible to differentiate the terminals located in different subnets covered by a physical MSC, therefore the roaming and handover of the terminal between the subnets can be implemented; and the roaming limitation also can be implemented through the MSC List and VLR List.

摘要： Embodiments of this application provide a method for controlling a terminal to use a wireless network, a system, and a related device. The method includes: obtaining, by a network decision device, service information of a terminal, constructing network use indication information, and delivering the network use indication information to a network trigger device; and triggering, by the network trigger device based on the network use indication information, the terminal to use a wireless network corresponding to the service information. According to the method, an operator can assign, based on a service requirement of the operator, the terminal to use a specific wireless network, so that the terminal can use in time a wireless network that is consistent with a requirement of the operator. This helps improve network use efficiency for the operator, and can prevent a service of the terminal from being affected.

摘要： The present invention relates to the network communication field and discloses a method and an apparatus for processing IP multimedia subsystem (IMS) services and an IMS. The method for processing IMS services includes: receiving a service request of a user forwarded by a proxy call session control function (P-CSCF); requesting a home subscriber server (HSS) to query for whether the user is already registered; when the HSS finds that the user is already registered, receiving a successful response and information of a serving call session control function (S-CSCF) allocated to the user; and forwarding the service request to the S-CSCF for serving the user. The IMS includes a P-CSCF, an interrogating call session control function (I-CSCF), an S-CSCF, and an HSS. In the present invention, when the P-CSCF loses the registration information of the user, the HSS is configured to query for whether the user is already registered and obtain the information of the S-CSCF. In this way, the registered user may perform session services without re-registration, thus improving the service experience.
摘要翻译：本发明涉及网络通信领域，并且公开了一种用于处理IP多媒体子系统（IMS）服务和IMS的方法和装置。用于处理IMS服务的方法包括：接收由代理呼叫会话控制功能（P-CSCF）转发的用户的服务请求; 请求归属订户服务器（HSS）查询用户是否已经注册; 当HSS发现用户已经被注册时，接收成功的响应和分配给用户的服务呼叫会话控制功能（S-CSCF）的信息; 并将所述服务请求转发给所述用户服务的S-CSCF。 IMS包括P-CSCF，询问呼叫会话控制功能（I-CSCF），S-CSCF和HSS。在本发明中，当P-CSCF丢失用户的注册信息时，HSS被配置为查询用户是否已经被注册，并获得S-CSCF的信息。以这种方式，注册用户可以执行会话服务而不重新注册，从而改善服务体验。

摘要： Embodiments provide a service request processing method, a related device, and a communications system in an IMS network. In the embodiments, because 5GC network slices correspond to different services, P-CSCFs in the IMS also correspond to different service information. After receiving a terminated service request sent by an I-CSCF, a first S-CSCF can obtain an address of a corresponding P-CSCF based on terminated service information carried in the terminated service request. Then, the first S-CSCF sends the terminated service request to the P-CSCF corresponding to the address, and the P-CSCF processes the terminated service request. The embodiments resolve a technical problem of how an S-CSCF in the IMS sends a terminated service request for UE to a corresponding P-CSCF for processing after the UE accesses the IMS through different 5GC network slices.
