Problems solved by technology

[0010] In practical applications, the above scheme has the following problems: the paging process may not be executed correctly, and the data arriving at the source FA is lost
And if the handover is also successfully carried out, the target FA will re-initiate paging after receiving the data from the HA. At this time, because the MS has left the idle mode, the paging in this case will fail
On the other hand, if the paging initiated by the original FA fails, and the target FA initiates a new paging after receiving the data from the HA after the handover is completed, since some data have been sent to the original FA at this time, these data will not be able to be transmitted to the MS, resulting in the loss of data reaching the original FA

Embodiment Construction

[0052] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0053] The core of the present invention is that if the anchor PC receives a paging request for the MS from the serving FA during the FA relocation of the MS, it will indicate that the MS is in the FA relocation by carrying in the MS_Info_Response message The code of the process informs the service FA to stop paging, and after the FA relocation process ends, the FA where the MS is located re-initiates paging.

[0054] The principle of the present invention is briefly introduced above. Based on this principle, the paging method in the WiMAX system of the first embodiment of the present invention will be described in detail below.

[0055] As shown in FIG. 5, in step 501, after the anchor PC receives the location update request message, it compares the address of the...

Abstract

The method is used for making the paging process be correctly executed when both the paging process and FA re-location process simultaneously break out. In the invention, the Anchor PC is used to decide if the MS in paging is currently at the FA relocation process; if yes, informs the serving FA to stop the paging; after FA relocation process is completed, the paging process is re-initiated..

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to the paging technology in the Worldwide Interoperability for Microwave Access (WiMAX) system. Background technique [0002] With the development of communication technology and the growth of user demand, data services have developed rapidly. The rapid growth of data services has made people's demand for communication bandwidth increasing. Broadband access is showing a huge market to the industry. In order to break through the bandwidth bottleneck of the access network, a variety of broadband access technologies have been introduced. Compared with wired access, broadband wireless access (Broadband Wireless Access, "BWA" for short) technology using wireless access has obvious advantages such as flexibility, convenience, mobility, and less investment. Communications (The Third Generation, referred to as "3G"), broadband wireless local area network (Wireless Local Area Network, ...
