Problems solved by technology

[0006] Embodiments of the present invention provide a location information acquisition method, device, and IMS, which solves the problems in the prior art when the called user opens the service of the same number or one-number dual-phone (one-number multiple machines / multi-card one-number) service. At this time, the called user's ringing number answers the call in area A, but the location information obtained by the network side is the location information of the called user's called number in area B. As a result, the location information cannot be accurately obtained, which affects billing and management. The problem

Embodiment 1

[0062] Embodiment 1. The embodiment of the present invention provides a method for acquiring location information, such as image 3 Shown include:

[0063] S101. The SCP server obtains the location information of the called number.

[0064] It should be noted that in actual applications, because the intelligent network service needs to obtain the location information of the called number, the called number here has enabled the intelligent network service by default; if the called number has not activated the intelligent network service, there is no need to Step S101, Step S102, Step S103 and Step S104.

[0065] S102. The MMTEL server obtains the synchronous number signed by the called number.

[0066] It should be noted that, in an actual application, if the called number is not subscribed to a synchronous number, the location information stored in the SCP AS is the location information of the called number.

[0067] S103. The MMTEL server generates a first INVITE request w...

Embodiment 2

[0093] Embodiment 2, the embodiment of the present invention provides a kind of SCP server 11, such as Figure 8 Shown include:

[0094] Transceiving unit 110, configured to obtain the location information of the called number;

[0095] The transceiver unit 110 is also configured to receive the first INVITE request sent by the MMTEL server; wherein, the first INVITE request includes: the synchronous number;

[0096] The processing unit 111 is configured to, when it is determined that the first INVITE request received by the transceiving unit 110 includes information indicating to query the location information of the synchronous number, obtain the location information of the synchronous number and transfer the location of the called number acquired by the transceiving unit 110 The information is replaced with the location information of the ringing number.

[0097] Optionally, the processing unit 111 is further configured to generate a second INVITE request; wherein, the sec...

Embodiment 3

[0100] Embodiment three, the embodiment of the present invention provides a kind of MMTEL server 12, such as Figure 9 Shown include:

[0101] The data transceiving unit 120 is used to acquire the synchronous number subscribed by the called number;

[0102] The data processing unit 121 is configured to generate a first INVITE request when determining that the terminal device using the synchronous number obtained by the data transceiving unit 120 answers the call; wherein, the first INVITE request includes: the synchronous number.

[0103] Optionally, the data transceiving unit 120 is also configured to receive the second INVITE request sent by the SCP server; the data processing unit 121 is specifically configured to determine that the second INVITE request obtained by the data transceiving unit 120 includes an instruction to activate an intelligent network service. When sending messages, obtain the ringing number subscribed by the called number.

[0104] Optionally, the dat...

Abstract

The embodiment of the invention provides an acquisition method and device of location information, and an IMS, relates to the technical field of the communication, and solves a problem that the charging and the control are influenced since the location information cannot be accurately acquired in the situations that a co-vibrating number of a called user answers the calling at an A area, but the location information acquired by a network side is the location information that the called number of the called user is located at a B area when the called user opens the same-number type or one-number dual-unit (one-number multi-unit / multi-card one-number) service in the prior art. The method comprises the following steps: a SCP server acquires the location information of the co-vibrating number and replaces the location information of the called number with the location information of the co-vibrating number when determining the fact that the first INVITE request contains the information indicating to query the location information of the co-vibrating number. The acquisition method provided by the embodiment of the invention is used for acquiring the location information.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a location information acquisition method, device and IMS. Background technique [0002] The voice service based on the Internet Protocol Multimedia Subsystem (English full name: Internet Protocol Multimedia Subsystem, abbreviation: IMS) (English full name: Voice over LTE, abbreviation: VoLTE) will become the main solution for future voice services. Services such as business, supplementary business and intelligent network will be triggered and provided by IMS. [0003] With the development of the network and the rapid popularization of smart terminals, the data services in the mobile network continue to increase, and the service requirements of users are increasingly rich and diversified. Services such as one number with multiple cards and one card with multiple numbers have a wide range of application scenarios; The card business refers to multiple terminal forms...
