Abstract

The present invention discloses a method for implementing a redirection service for UEs sharing a PUI in an IMS, comprising: when a UE in a PN registers at a PNM AS, the PNM AS fetching the UE Identity and establishing a corresponding relationship between the identity and the PUI; when determining to route an initial request message of a terminating call of a UE in the PN routed by an original S-CSCF to a configured UE sharing the PUI, the PNM AS adding the configured UE Identity into a redirected initial request message and sending it to the original S-CSCF which forwards the message to a redirection S-CSCF; and the redirection S-CSCF uniquely locating the configured UE according to the identity or both the identity and the PUI in the message. The present invention can redirect a session initial request to a configured UE sharing a PUI with other UEs.

Dependent claims

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.

A system for implementing a redirection service for User Equipments (UEs) sharing a Public User Identity (PUI), comprising UEs, a Serving Call Session Control Function (S-CSCF) in an Internet Protocol Multimedia Core Network Subsystem (IMS), and a Personal Network Management Application Server (PNM AS) connected to the S-CSCF, wherein,

the S-CSCF comprises:
a redirection trigger unit, used to invoke a terminating call service control logic to process an initial request message of a terminating call of a UE in a Personal Network (PN), to match with initial filter criteria, and to route the initial request message to the PNM AS;
and
a redirection processing unit, used to uniquely locate a configured UE according to an identity or both the identity and a PUI in a redirected initial request message after receiving the redirected initial request message, and to invoke the terminating call service control logic to process the initial request for a terminating call of the configured UE;
the PNM AS comprises:
a storage unit, used to store a Private User Identity (PVI), a PUI, an identity and registration state information of a UE in a PN, as well as indication information of a configured UE in the PN;
and
a redirection control unit, used to add an identity of a configured UE into a redirected initial request message and send the redirected initial request message to an original S-CSCF when determining to route an initial request message of a terminating call of a UE in a PN routed by the original S-CSCF to the configured UE with a shared PUI according to a configuration of the PN.
