Abstract: Embodiments of the present invention provide a method, apparatus, and system for a handover to a circuit switched domain. The method includes: selecting an MSC capable of both CSFB and SRVCC for a UE; and selecting, if a location service of a CS domain triggers an SRVCC procedure for the UE when the UE has a VOIP service in progress, the MSC capable of both CSFB and SRVCC in the SRVCC procedure, so that the UE, after being handed over to the CS domain, accesses the MSC and implements the location service of the CS domain. The apparatus includes: a first selecting module and a second selecting module. The system includes a UE and the apparatus. The embodiments of the present invention enable the UE with the VOIP service in progress to be correctly handed over to the CS domain and implement the location service.

Abstract: Embodiments of the present invention provide a method, an apparatus and a system for handling node failure. The method for handling node failure includes: sending, by an intermediate node, a context processing request message to a remote node when detecting that a first node occurs a failure, where the context processing request message is used to instruct the remote node to delete context information associated with the first node and the intermediate node; and deleting the context information associated with the first node and the intermediate node, by the remote node, according to the request message. The technical solution can enable the remote node to process the context information associated with the first node in time

Abstract: This application provides a communication method and a communication apparatus. The method includes: A service communication proxy receives a service request message sent by a service invoking network element. The service request message is used to request to invoke a first service, the service request message indicates version information of a first service-based interface supported by the service invoking network element, and the first service-based interface is an interface corresponding to the first service. The service communication proxy selects a first service providing network element based on the service request message. The first service providing network element and the service invoking network element support a same version of the first service-based interface. The service request message indicates the version information of the first service-based interface supported by the service invoking network element, so that the service communication proxy may determine an appropriate service providing network element.

Abstract: In a method for performing access control on user equipment, a mobility management device receives from an access node device an access type parameter of the user equipment. The access type parameter indicates a radio access type of the user equipment or a type of the access node device. The mobility management device determines, based on the access type parameter, a connection type of the user equipment in accessing a core network, wherein the connection type is either single connectivity or dual connectivity. The mobility management device then performs access control on the user equipment based on the connection type of the user equipment.
