Example Embodiment

[0092] Example one

[0093] As shown in Figure 1, for the connection closure initiated by the AT, in order to avoid the occurrence of asynchronous sleep and wake-up between AT and AN caused by the failure of the AN not receiving the ConnectionClose message initiated by the AT, Timer=Timerl can be set, and AT follows the following formula Select Period:

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

Example Embodiment

[0108] Example two

[0109] As shown in Figure 2, for the connection close initiated by AN, in order to avoid the occurrence of asynchronous sleep and wake-up of AT and AN caused by the failure of the ConnectionClose message returned by the AN to receive the ConnectionClose message returned by the AT, Timer=Timer2 can be set, and AT follows the following formula Select Period:

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

Example Embodiment

[0116] Example three

[0117] Let 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 hibernation and wake up synchronization method of an AT and an AN. The invention comprises that a reference Timer is set; a first party of the AT and the AN defines the hibernation cycle value according to the own T12, T23 thereof and set Timer; a second party defines the hibernation cycle value according to own T12 and T23 thereof. Then the AT and the AN calculate the respective own wake up time slot T according to the own defined hibernation cycle and carries out the switchover of the hibernation and wake up according to the own wake up time slot T thereof. The invention also provides an AT, comprising a hibernation cycle determination unit, a wake up time slot calculation unit and a hibernation wake up unit. In addition, the invention also provides an AN, comprising a hibernation cycle determination unit, a wake up time slot calculation unit and a hibernation wake up unit. The invention is capable of ensuring the synchronization of both the hibernation and wake up of the AT and the AN, and decreasing the paging loss 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 ...
