In this embodiment, a certain range of device identifiers are allocated to an M2M terminal having a low mobility characteristic, and the device identifier may be an IMSI (Internationa l Mobi le Subscr iber Ident). If icat ion Number, but not limited to this. The access network determines whether the M2M terminal has a low mobility characteristic according to the IMSI of the M2M terminal, and determines, according to the low mobility characteristic of the M2M terminal, that the paging is sent in the cell range in which the M2M terminal is located or in the range of the cell and the neighboring cell. .

As shown in FIG. 8, the method for sending a paging includes:

801. The BSS obtains a cell identifier of the M2M terminal, and configures an IMSI range of the M2M terminal with a low mobility feature, where the low mobility feature includes fixed or moving in a small range.

Specifically, setting a certain range for the IMSI of the M2M terminal with low mobility, and specifically setting the IMSI range of the M2M terminal having the fixed immobility characteristic, and the IMSI range of the M2M terminal moving in a small range, and The IMSI range is saved in the BSS. Based on the IMSI of the M2M terminal and the IMSI range, the BSS can determine whether the M2M terminal has low mobility, and has characteristics of being fixed or moving in a small range.

In the registration or location update process, or during the cell update process, the M2M terminal is located in the small The zone ID is saved in the BSS.

802. When the network pages the M2M terminal, the BSS sends the paging according to the IMSI of the M2M terminal and the stored IMSI range of the M2M terminal with low mobility characteristics, and the cell identifier of the M2M terminal. Specifically, the BSS will The IMS I of the terminal is compared with the stored IMSI range of the M2M terminal with low mobility characteristics. If the IMSI belongs to the IMSI range, the M2M terminal has a low mobility characteristic; further, it is determined that the IMSI belongs to a fixed state. The IMSI range of the characteristic M2M terminal, or the IMS I range of the M2M terminal having a small range of movement.

If the IMS I belongs to the IMSI range of the M2M terminal with the fixed immobility feature, the low mobility characteristic of the M2M terminal is fixed, and the BSS sends the paging to the saved cell range;

If the IMS I belongs to the IMS I range of the M2M terminal that moves in a small range, the low mobility characteristic of the M2M terminal is to move in a small range, and the BSS sends the search to the saved cell and the neighboring cell of the cell. call.

Further, the method may further include:

The BSS records the number of pagings. When the BSS receives the first paging message of the M2M terminal, and the BSS locally stores the cell information to which the M2M terminal belongs and the IMSI range of the M2M terminal with low mobility characteristics, the BSS is based on the M2M terminal. IMSI, only in the range of the saved cell, or in the range of the saved cell and neighboring cell; if it is a retransmission page after the failure, that is, not the first page, then the BSS is under the jurisdiction Posting is performed within all cell areas.

According to the method for sending a paging provided by the embodiment of the present invention, the BSS determines, according to the device identifier of the M2M terminal and the device identification range of the M2M terminal with low mobility characteristics configured in the BSS, the M2M terminal in the cell where the M2M terminal is located. And paging is sent within a neighboring cell of the cell. Compared with prior art paging in the entire RA/LA range, the embodiment of the present invention can be based on M2M The low mobility characteristic of the terminal sends a paging in the cell range or the neighboring cell range of the cell, thereby reducing the paging amount and reducing the occupation of paging channel resources.
