Problems solved by technology

In this way, due to the conflict between the paging request and the location update, the paging request fails and the location update request fails
When the MSC retransmits the paging, it still uses the LAC that has not been updated in the VLR, which will cause the secondary paging failure and increase the waiting time for the called MS to respond; if the MSC uses the extended LAC paging, it will increase the paging of other base stations. channel pressure
If there are a large number of users at the boundary of the location area and the location updates are frequent, it will have a considerable impact on the paging success rate and location update success rate of the wireless communication system

Embodiment 2

[0042] The difference between the second embodiment and the first embodiment is that in the second embodiment, it is not necessary to change the process of retransmitting the paging after the paging response timer expires in the prior art. It is enough to respond to the location update of the target MS and use the new location information in the paging retransmission. In the first embodiment, the paging response timer is reset immediately after receiving the location update request of the target MS, which reduces the waiting time for paging retransmission and further shortens the time required for the MSC to page the target MS.

[0043] The device implementing Embodiment 1 or Embodiment 2 of the paging retransmission method of the present invention may have Figure 5 With the structure shown, the communication device can be used as an MSC / VLR in a wireless communication system. See Figure 5 , the paging unit 520 performs information interaction with the location updating un...

Abstract

A resending method of paging includes receiving position update request of object MS when object MS response paging request is waited, responding position update request of said object MS and using updated position information to resend paging request to said object MS. The device used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a paging retransmission method and equipment for realizing paging retransmission. Background technique [0002] In a wireless communication system, when the network side pages a mobile station (MS, Mobile Station), the mobile switching center (MSC, Mobile Switching Center) searches the location area of ​​the target MS in the visitor location register (VLR, Visitor Location Register) Code (LAC, Location AreaCode) and other location information. Using the location information of the target MS, the MSC sends a paging request message through a base station controller (BSC, Base Station Controller). If the target MS is in an idle state, it will respond to the paging request message; if the target MS is in a busy state, it will not respond to the paging request message, causing the MSC paging failure this time. When the MSC sends the paging request message, it starts a timer and...
