A method for connecting a terminal outside the range of its home network, to a network of a visited area covered by a plurality of networks. The method includes sending a request relating to the connection, including an identifier relating to the visited area, receiving a response message to the request, including a list of at least one network of the plurality of networks, to which the terminal should connect in priority, disconnecting the terminal and connecting the terminal to the priority network of the list. A processing method includes receiving the request including an identifier relating to the visited area, obtaining, on the basis of the identifier, the list of at least one network from the plurality of networks, to which the terminal should connect in priority, and sending a response message to the request, including the list.

The present invention discloses a user equipment context management method, apparatus, and device, and relates to the field of communications technologies. The method includes: receiving, by a first control plane entity, a service request message of user equipment UE, where the service request message includes service information requested by the UE; obtaining location information of the UE, determining, based on the service information requested by the UE, a mobility level of a service requested by the UE, determining, based on the location information of the UE and the mobility level of the service, an effective range of a context of a network resource bearing the service of the UE, and managing the context based on the effective range of the context.

A method and apparatus is provided that improves the quality of voice calls in a mobile communication network. The method of performing transmission/reception of signals in an evolved Node B (eNB) of a mobile communication system includes: receiving a first message including service request information from user equipment (UE); transmitting a second message including the service request information to an Mobility Management Entity (MME); receiving a third message including context information for the UE from the MME; and determining an inactivity timer value for the UE based on the context information. The method and apparatus can maintain, when a voice call is created, connection with calling UE from when the called UE answers the call until the call is set up, thereby preventing part of a caller's voice data from being lost.
