Embodiment Construction

[0082] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0083] like figure 2 As shown, it is an architecture diagram of a system for acquiring user location information provided by an embodiment of the present invention. Wherein, when the SCP in the intelligent network needs to obtain the information of the location of the UE, the SCP sends a first ATI request to the IM-SSF entity in the IMS network, so as to request the IM-SSF entity to search through the server storing user data The ...

Abstract

The invention relates to the technical field of communication, in particular to a method, a device and a system for acquiring user location information. The embodiment of the invention provides the method for acquiring the user location information, a service control point (SCP) in an intelligent network transmits a first arbitrary time query request which carries a location acquisition mark and a user equipment (UE) mark to an internet protocol multimedia-service switching function (IM-SSF) entity in an internet protocol multimedia subsystem (IMS) when needing to obtain the UE location information, and the IM-SSF entity obtains the T-ADS information according to the location acquisition mark and the UE mark, then determines an access domain to be connected with UE and sends the UE location information in the access domain to be connected to the SCP. By utilizing the method provided by the embodiment of the invention, the SCP treatment load when the UE location information is obtained can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, device and system for acquiring user location information. Background technique [0002] With the evolution of traditional 2G (2nd Generation, second generation) network or 3G (3rd Generation, third generation) network to LTE (Long Term Evolution, long term evolution) network, based on CS (Circuit Switching, circuit switching) domain The voice service also begins to evolve to the voice service based on the PS (Packet Switching, packet switching) domain. [0003] In addition to supplementary services such as number display services, call barring services, and forwarding services, the voice services provided by traditional 2G or 3G networks also include a large number of intelligent services, such as Prepaid Service (PPS) services. And virtual private number (Virtual PrivateNumber, referred to as: VPN) service. These smart services are generally f...
