Problems solved by technology

When traffic peaks, the impact of network-wide paging is more prominent, and may even lead to business congestion or interruption, causing serious consequences
[0003] There is no clearly defined interface protocol between the mobile switching center MSC and the visitor location register VLR (this interface is not fully operational specified. It is strongly recommended not to implement the B-interface as an external interface. GSM 09.02), the mobile switching center MSC to the user After sending out the whole network paging and receiving the paging response, the mobile switching center MSC does not refresh the user data in the visitor location register VLR immediately due to various reasons, and the agreement recommends that there is no mandatory requirement in this regard, resulting in the user actively refreshing Before visiting the user data in the location register, the mobile switching center MSC always sends the whole network paging, causing a lot of waste of network resources

Embodiment 1

[0020] see figure 1 , figure 1 It is a flowchart of location update after network-wide paging of the present invention, and the flowchart includes the following steps:

[0021] The mobile switching center MSC issues paging to the mobile terminal, and the paging request message contains the Paging Type information element;

[0022] The mobile terminal receives the paging, detects the Paging Type information element, judges that the paging is a network-wide paging, and records the network-wide paging;

[0023] The mobile terminal enters the idle state after completing the service, and initiates a normal location update request;

[0024] After the location update is completed, no matter whether it is successful or not, the mobile terminal clears the record of the whole network paging.

[0025] By detecting the newly added Paging Type information element, the mobile terminal judges whether the received paging type is general paging or network-wide paging. If it is detected tha...

Embodiment 2

[0032] The mobile switching center MSC issues network-wide paging to the mobile terminal; the mobile terminal receives the network-wide paging and sends a network-wide paging response to the MSC; after the MSC receives the paging response from the mobile terminal, the MSC queries the VLR for the When the user's paging information or the data of the called user is queried again, the location area cell information carried in the paging response is refreshed to the VLR; the VLR updates the location area cell information sent by the MSC to the user data; subsequent paging requests Initiate according to the latest location area information, no need to send network-wide paging.

[0033] The method for actively updating the location information in the VLR by the MSC of the present invention avoids the MSC from repeatedly issuing the whole network paging and avoids the waste of network resources.

Abstract

The present invention discloses position updating method. It contains mobile switching center MSC down transmitting all network paging, indicating this paging as network paging in paging request message, mobile terminal receiving paging request message and judging said paging being all network paging, in mobile terminal next time entering free state, immediately to make general position updating and updating network side user data; or MSC receiving mobile terminal paging responding, actively refreshing positional information in visiting location register VLR. The present invention avoids MSC repeating down transmitting all network paging and network resources wastage.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for updating a location. Background technique [0002] In the mobile network, the MSC sometimes needs to issue network-wide paging to users, but in the existing network, the capacity of the mobile switching center MSC increases rapidly, and due to the new features of the existing network such as large local network, the entire network Paging takes more and more resources. During traffic peaks, the impact of network-wide paging is even more prominent, and may even lead to service congestion or interruption, causing serious consequences. [0003] There is no clearly defined interface protocol between the mobile switching center MSC and the visitor location register VLR (this interface is not fully operational specified. It is strongly recommended not to implement the B-interface as an external interface. GSM 09.02), the mobile switching center MSC to the user After ...
