Problems solved by technology

[0019] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art: in the network operation mode I, during the process of UE attaching to the PS domain and CS domain, due to UE defects, wireless network signal instability or protocol Incomplete and other factors, the type of UE attach message is not joint location update, so the SGSN in the PS domain cannot normally notify the MSC / VLR in the CS domain to perform joint location update
The UE fails to address the called party, therefore, the UE cannot be called

Embodiment 1

[0113] In order to enable the terminal to be called in time after it is turned on or roaming, the embodiment of the present invention provides a method for synchronizing the location information of the packet domain and the circuit domain. like figure 1 As shown, the method for synchronizing location information between the packet domain and the circuit domain in the embodiment of the present invention includes:

[0114] 101. The circuit domain service device obtains the packet domain service device information corresponding to the terminal registered in the user home location register;

[0115] When the terminal addresses the called party, the CS domain service device will receive the request for extracting the user port / request for extracting the roaming number sent by the user home location register. Therefore, the request can carry the corresponding information of the terminal registered in the user home location register. Packet domain service device information.

Embodiment 2

[0123] The method for synchronizing location information between packet domain and circuit domain described in Embodiment 1 will be further described in detail below. This embodiment of the present invention is applicable to MSC / VLR: SGSN(1:1,1:n,m:1,m : The various networking of n), need the service equipment of CS domain, the service equipment of PS domain and HLR support, such as figure 2 As shown, the method for synchronizing location information between the packet domain and the circuit domain in the embodiment of the present invention includes:

[0124] 201. When the terminal is addressing the called party, the circuit domain service device receives the request for extracting the user port / request for extracting the roaming number (PSI_Req / PRN_Req) ​​sent by the user home location register to the terminal, and the request carries the packet domain location information registered in the home location register;

[0125] Specifically, it can be:

Embodiment 3

[0194] In Embodiment 1, according to the PS domain service equipment information corresponding to the terminal recorded in the circuit domain service equipment and the PS domain service equipment information registered in the user home location register, the PS domain and the circuit domain registered by the terminal in the user home location register are determined. Whether the domain location information is synchronized. It is also possible to determine whether the PS domain and CS domain location information registered by the terminal in the user home location register are synchronized according to the location area identification code of the terminal after determining that the paging result of the terminal is timed out. ,Such as image 3 As shown, the method for synchronizing location information between the packet domain and the circuit domain in the embodiment of the present invention includes:

[0195] 301. When the terminal addresses the called party, the CS domain se...

Abstract

The embodiment of the invention discloses a method for synchronizing the location information of a packet switch (PS) and a circuit switch (CS), and a device and a system thereof, and solves the problem that in a combined mode, when a terminal roams between the packet switch and the circuit switch, because the location information of the terminal in the circuit switch is not correctly updated dueto the cooperation problem between the terminal and a network side, the terminal can not be called. The method mainly comprises the steps of terminating flow activation, and detecting by the network side whether the location information of the circuit switch in which the terminal locates matches with the circuit switch location information registered in a user home location register (HLR); and ifmismatching is detected and the statues of the circuit switch in which the terminal locates is idle, notifying the terminal to initiate combined location update by packet switch serving equipment. The method can be used for maintaining location update of the circuit switch.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for synchronizing location information between packet domain and circuit domain. Background technique [0002] The communication network is divided into a packet domain (Packet Switch, PS domain) and a circuit domain (Circuit Switch, CS domain). The PS domain handles data services, such as mobile Internet access; the CS domain handles voice services, such as voice calls and short messages. [0003] The Serving General Packet Radio Service Support Node (Serving GPRS Support Node, Serving GSN, SGSN) is a serving device in the PS domain and is used to manage data services. Mobile Switching Center (Mobile Switching Center, MSC) / User Visiting Location Register (Visiting Location Register, VLR) is a service device in the CS domain, used to call User Equipment (User Equipment, UE) and store dynamic information of users; User Home Location Register (Home Lo...
