Embodiment 1

[0044] image 3 It is a schematic diagram of Embodiment 1 of a location update method according to the present invention.

[0045] In order to effectively solve the problem of location update and paging conflict, the following modifications are made to the existing network elements in this embodiment:

[0046] 1) Network element transformation 1: In all VLRs (such as image 3 In VLR2, PVLR), a user parameter is added to indicate the identification information of the location update state, such as the identification information (user parameter) is the location update state "Location Update Flag", which is used to reflect whether the user is in the location update state. During application, the default value can be set to 0, that is, not in the location update state. Specifically, the default value can also be flexibly set according to needs, as long as two states can be set to indicate whether the user enters the location update state;

[0047] 2) Network element transformati...

Embodiment 2

[0063] Figure 4 It is a schematic diagram of another embodiment of the location update method according to the present invention. Figure 4 and image 3 Similarly, it is another case of location update, mainly for the process that the MS needs to use the IMSI to identify itself to update the location when the previous VLR cannot respond to the IMSI. The specific process can be found in the following Figure 4 shown.

[0064] Figure 4 In the embodiment, when VLR2 cannot obtain the IMSI from the PVLR, the new MSC requires the MS to provide the IMSI, and after obtaining the IMSI confirmation, it actively sends a location update request to the HLR, and the subsequent process is the same as image 3 Similar, HLR is receiving this update location request, and the user's location update status "Location Update Flag" is configured as 1; " is configured as 0, indicating that the user has left the location update state.

[0065] The above embodiments of the location update method...

Embodiment 3

[0067] Figure 5 It is a schematic diagram of Embodiment 1 of the paging processing method according to the present invention. In this embodiment, the re-addressing function is added on the (Gateway MSC, GMSC for short), and the call is directed to the new MSC where the user's location is updated, so as to ensure that the paging message can be received after the user's location is updated. In the present embodiment, the GMSC itself is also an MSC (in the flow chart of the present embodiment, it refers specifically to the MSC that the external call is transferred over). After the external call is transferred through its GMSC, the GMSC is addressed to the HLR , and connect the call after finding the MSC where the called mobile phone is located, and paging the mobile phone by the MSC where the called mobile phone is located. Such as Figure 5 As shown, the paging process in this embodiment includes:

[0068] Step S502: the network side sends an initial address message (IAM) to...

Abstract

The invention discloses a method for updating a position and processing a paging conflict, a VLR, an HLR, a GMSC and a system. The method for updating the position comprises that: the VLR and / or the HLR is respectively added with identifier information used for representing a position updating state; when a user performs position updating, the identifier information on the VLR and / or the HLR before the position updating is configured to enter the position updating state; and when the position updating is finished, the HLR configures that the identifier information does not enter the position updating state. The HLR and the VLR are respectively added with the identifier information representing position updating to strengthen the management on the position updating, and different paging processing is carried out according to the identifier information to ensure that the user can receive paging messages after the position updating, so that the problems of position updating and paging conflict are radically solved on the basis.

Description

technical field [0001] The present invention relates to the paging technology in the field of communication, in particular to a position update, paging conflict processing method, VLR, HLR, GMSC and system. Background technique [0002] In the current network, a roaming mobile user can move freely in the GSM network, and the network keeps track of the mobile user's location. In order for the network to track the current location of the mobile user, a mobile station (Mobile Station, hereinafter referred to as MS) needs to notify the system when it changes its location area, and this process is called location update. [0003] There are two situations for location update: one is when the MS enters a new Visitor Location Register (VLR) location area and requests location update using the temporary mobile subscriber identification number assigned by the previous VLR (PVLR) (Temporary Mobile Subscriber Identity, hereinafter referred to as TMSI) to identify itself; the second is ...
