The embodiments of the present invention provide a user location information acquisition method and a server. The method includes the following steps that: a call request initiated by a user end is received, wherein the call request contains calling user information; and if judgment is carried out according to the calling user information, and it is learnt that user location information needs to be obtained, whether the call request contains the corresponding user location information is judged, and if the call request contains the corresponding user location information, the user location information is acquired from the call request, wherein the user location information contains calling user location information and / or called user location information. The server is used for performingthe above method. According to the method provided by the embodiments of the present invention, when the call request sent by the user end is received, and the user location information is needed to be obtained; whether the call request contains the needed user location information is judged; and if the call request contains the needed user location information, the user location information is directly obtained from the call request, the home user server does not need to re-query the user location information, and thus, call delay can be decreased.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method and server for acquiring user location information. Background technique [0002] VoLTE (Voice over LTE) refers to end users accessing EPC (Evolved Packet Core, packet core network) through LTE (Long Term Evolution, long-term evolution network), and then IMS (IP Multimedia Subsystem, IP multimedia subsystem network) as the user Provide 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 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, eSRVCC (Enhanced Single RadioVoice Call Continuity, enh...
