USER DEVICE SELECTION

摘要

A method may include receiving, at an application server, a session initiation protocol (SIP) message including a public user identifier (ID) associated a user. The public user ID corresponds to a plurality of user devices. The method also includes determining an applicable order of alerting at least one of the plurality of user devices. The method further includes identifying at least one available user device associated with the user, based on a terminal identifier (ID) associated with each at least one available user device. The method also includes selecting a user device from the at least one available user device based on the applicable order of alerting. A SIP invite message, including a terminal ID for the selected user device, is generated. The method includes sending the SIP invite message to the selected user device based on the applicable order of alerting, and receiving a response to the SIP invite message.

1. A computer-implemented method comprising:
receiving, at a serving call session control function (S-CSCF) in a network and from a user device, a session initiation protocol (SIP) register message including a terminal identifier (ID) of the user device and a public user ID associated with a user of the user device; sending, to a home subscriber server (HSS), a request for user authentication data, wherein the request includes the public user ID and the terminal ID; authenticating the user device based on the user authentication data; determining a registration context of the user device based on the terminal ID and the public user ID; storing the registration context for the user device; sending a SIP 200 OK message to the user device; and sending a SIP register message to an application server, wherein the SIP register message includes the terminal ID and the public user ID, and wherein the application server is to provide an incoming session to the user device based on the registration context of the user device.
