Problems solved by technology

[0043] That is, if the AN does not start computing T until after one or more wake-up slots of the AT 12 and T 23 , it may happen that the sleep and wake-up of AT and AN are not synchronized, for example, AN is sending paging while AT is sleeping, resulting in paging loss

Embodiment 1

[0093] see figure 1 As shown, for the connection close initiated by AT, in order to avoid the occurrence of out-of-synchronization between sleep and wake-up of AT and AN caused by AN not receiving the ConnectionClose message initiated by AT, Timer=Timer1 can be set, and AT can select Period according to the following formula:

[0094] Period = Period 1 , t T 12 + Timer 1 Period 2 , T 12 + Timer 1 ≤ t ...

Embodiment 2

[0109] see figure 2As shown, for the connection close initiated by AN, in order to avoid the out-of-sync situation between AT and AN sleep and wake-up caused by AN not receiving the ConnectionClose message returned by AT, Timer=Timer2 can be set, and AT can select Period according to the following formula:

[0110] Period = Period 1 , t T 12 + Timer 2 Period 2 , T 12 + Timer 2 ≤ t ...

Embodiment 3

[0117] Set Timer=Max(Timer1, Timer2), AT selects Period according to the following formula:

[0118] Period = Period 1 , t T 12 + Max ( Timer 1 , Timer 2 ) Period 2 , T 12 + Max ( Timer 1 , ...

Abstract

The invention discloses a dormancy and awakening synchronization method of an access terminal (AT) and an access network (NT), including: setting a reference time period Timer; a first party of the AT and the AN determining the dormancy cycle value according to the own T12, T23 thereof and the set Timer; a second party determining the dormancy cycle value according to the own T12 and T23 thereof; then the AT and the AN calculating the respective own awakening time slot T according to the own determined dormancy cycle and respectively carrying out the switchover of the dormancy and awakening according to the own wake up time slot T thereof. The invention also provides an AT, comprising a dormancy cycle determination unit, an awakening time slot calculation unit and a dormancy awakening unit. In addition, the invention also provides an AN, comprising a dormancy cycle determination unit, an awakening time slot calculation unit and a dormancy awakening unit. The invention can ensure the synchronization of both the dormancy and awakening of the AT and the AN, and decrease the paging lost problem caused by asynchronism of the AT and the AN.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for synchronizing dormancy and awakening of an access terminal and an access network, an access terminal and an access network. Background technique [0002] In a wireless communication system, a wireless link between an access terminal (Access Terminal, AT) and an access network (Access Network, AN) is mainly divided into the following states: initialization state, idle state and connection state. The initialization state refers to the process of capturing the network and synchronously accessing the network after the AT is turned on; the connection state refers to the open connection between the AT and the AN, which can send and receive forward and reverse data packets; the idle state refers to the AT after synchronizing on the network, establishing The state before the connection, in which the AN sends a paging message to the AT, and the AT monitors control ...
