Problems solved by technology

[0012]Since SIP only allows one IMPU to be registered at a time, if a user has more than one IMPU, it must go through multiple registrations, which will take a long time

Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0037] figure 2 It is the flow chart of UE initiating emergency registration provided by the present invention, such as figure 2 As shown, the specific steps are as follows:

[0038] Step 201: Pre-set the derivation rule of the E-IMPU derived from the IMPU, and save the derivation rule in the UE; pre-allocate a TEL URI format IMPU in the HSS for each contracted UE, and set the TEL URI The IMPU of the format can be associated with any E-IMPU of the subscribed UE and constitute an implicit registration set.

[0039]The derivation rule is set by the operator. For example, the derivation rule can be set to add "emergency" in front of the IMPU domain name to get E-IMPU, such as: IMPU is: user1@operator.com, E-IMPU is: user1@ emergency.operator.com.

[0040] Specifically, the derivation rule can be stored in the SIM of the UE; the HSS pre-stores the identi...

Abstract

The invention discloses an emergency registration method of IMS domain, including: pre-setting the derivative rules, by which, IMPU derives E-IMPU, and pre-configuring an IMPU with the format of TEL URI for each contracted UE in HSS. When detecting that users initiate the request of emergency session, UE derives E-IMPU by its preservative IMPU according to the rules, and brings E-IMPU and IMPI in the emergency registration request to send to HSS. Then in the corresponding relations between its preservative IMPI and IMPU with the format of TEL URI, HSS finds IMPU with the format of TEL URI. In this invention, HSS only need to preserve the correspondence between all IMPI contracted with UE and IMPU with the format of TEL URI, not to preserve the recessive registration collection linked with E-IMPU, greatly reducing searching scope. Moreover, without the need of preservation of the recessive registration collection, HSS saves storage space. UE needs not to maintain E-IMPU separately.

Description

Technical field [0001] The invention relates to the technical field of emergency conversations, in particular to an emergency registration method of the Internet Protocol Multimedia Subsystem domain. Background technique [0002] The IP Multimedia Subsystem (IMS) is a subsystem that supports IP multimedia services proposed by the Third Generation Partnership Organization (3GPP) in the R5 version. Its core feature is the use of the Session Initiation (SIP) protocol and the independence of access. IMS is a multimedia control / call control platform in the packet (PS) domain. It supports conversational and non-conversational multimedia services and provides a general service platform for future multimedia applications. [0003] Emergency call is a unique voice service function in the mobile communication system. Even if the mobile terminal is set to restrict outgoing calls and the subscriber identity module (SIM) is not inserted, as long as the mobile network covers the area, when the...
