Abstract:
1. A method for implementing a redirection service for User Equipments (UEs) sharing a Public User Identity (PUI), used to implement a redirection service for UEs in a Personal Network (PN) in an Internet Protocol Multimedia Core Network Subsystem (IMS), comprising: when a UE in the PN registers in the PN through a Personal Network Management Application Server (PNM AS), the PNM AS fetching an identity of the UE and establishing a corresponding relationship between the identity and the PUI of the UE, the identity alone or together with the PUI being able to uniquely locate the UE; in the redirection service, when determining to route an initial request message of a terminating call of a UE in the PN routed by an original Serving Call Session Control Function (S-CSCF) to a configured UE with a shared PUI according to a configuration of the PN, the PNM AS adding an identity of the configured UE into a redirected initial request message and sending the redirected initial request message to the original S-CSCF, and the original S-CSCF forwarding the redirected initial request message to a redirection S-CSCF at which the configured UE is registered; and after receiving the redirected initial request message, the redirection S-CSCF uniquely locating the configured UE according to the identity or both the identity and the PUI therein, and invoking a terminating call service control logic to process the initial request for a terminating call of the configured UE.
