This application provides 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.

Method for controlling terminal to use wireless network and related device

Embodiments provide a service request processing method, a related device, and a communications system in an IMS network. In some 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.

Service request processing method, apparatus, and communications system

The present invention discloses a method and a system for implementing communications between multiple subnets covered by one physical Mobile Switching Center and an MSC. The method maps the MSC to multiple virtual MSCs that are logical MSCs within the physical MSC, each virtual MSC corresponds to one subnet that represents one or more location areas within the physical MSC, assigns to each of the multiple virtual MSCs a virtual MSC number, identifies a virtual MSC number of one of the virtual MSCs that is currently visited by the wireless mobile terminal, according to the current location area and the set relationship between each subnet that represents one or more location areas within the physical MSC and each virtual MSC number, and transmits the identified virtual MSC number of one of the virtual MSCs that is currently visited by a terminal when the wireless mobile terminal implements communications.

Method and system for implementing communications between multiple subnets and MSC

The present invention discloses a method and a system for implementing communications between multiple subnets covered by one physical Mobile Switching Center (MSC) and an 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.
