Abstract

The embodiments of the present invention provide a method and device for acquiring the location information of a called party. The method includes the following steps that: a call request is received,wherein the call request contains the information of the called party; the location information of the called party corresponding to the information of the called party is stored into a session initiation protocol message according to the information of the called party; and the session initiation protocol message is sent to each service scenario application server, so that the service scenario application servers can obtain the location information of the called party from the session initiation protocol message. The method is used for executing the VoLTE application servers. According to the method and device of the embodiments of the present invention, the location information of the called party is stored in the session initial protocol message through the VoLTE application servers, so that the location information of the called party can be obtained from the session initial protocol message, and therefore, the repeated query of the location information of the called party is reduced, and call delay time is shortened.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for acquiring called location information. Background technique [0002] VoLTE (Voice over LTE) refers to end users accessing the packet core network (Evolved Packet Core, EPC) through the long-term evolution network (Long Term Evolution, referred to as LTE), and then the IP multimedia subsystem network (IP Multimedia Subsystem, referred to as IMS) Provide users with high-quality audio and video services. LTE is an access network, EPC provides bearer for voice and data services, and IMS network provides basic supplementary voice / video services. VoLTE is the target solution of the mobile operator's 4G voice basic service plan, providing IP voice services based on the packet domain. VoLTE uses IMS to provide call control and service logic, and EPC to provide high-quality packet domain bearer. Before continuous coverage, c...
