Embodiment 1
[0090] For the first case first. FIG. 3 is a flowchart of entering the idle mode initiated by the MSS in Embodiment 1 of the present invention. As shown in Figure 3, the process of entering the idle mode initiated by the terminal in this embodiment is as follows:
[0091](1) When the MSS decides to enter the idle mode (IDLE MODE), it initiates a deregistration request (DREG_REQ) message, and the activation code (Action Code) in the message is set to 0x01, indicating that it is required to enter the idle mode, and the message format is 802.16e definition. After receiving this message, the Serving Base Station / Paging Agent (SBS / PA) will send a mobile terminal deregistration request (MSS Dreg Request) message to its local paging controller (the PC that manages this PA), and the message will carry the mobile terminal Terminal identification (MSS ID), base station identification (BSID), paging group identification (PG_ID), idle mode retention information (Idle Mode Retain Informa...
Embodiment 2
[0123] The above MS enters the idle mode and needs to save the context information of the MS to the anchor PC. The process may not be accompanied by the data channel release process, that is, after the serving BS decides that the MS can enter the idle mode according to the network side algorithm and obtains the paging parameters, Perform data channel release process. Therefore the flow process of this embodiment can also be replaced by following flow process (as shown in Figure 4):
[0124] After the PA / SBS receives the DREG_REQ message of the MSS, the PA / SBS sends an MSS Info Request message to its corresponding relay PC, requesting to determine whether it can enter the idle mode; MSS allocates PC ID, paging parameters, and the message carries MSID, idle mode reservation information, BSID, ASN-DPF ID, anchor authenticator ID and other terminal context information required for the terminal to enter idle mode. information, and send the information to the anchor PC through the ...
Embodiment 3
[0128] The following describes the situation that the MS needs to enter the idle mode after a period of time when the MSS initiates a request to enter the idle mode.
[0129] Fig. 5 is the process of entering the idle mode initiated by the MSS in Embodiment 3 of the present invention. As shown in Fig. 5, the process includes the following steps:
[0130] (1) When the MSS decides to enter the idle mode, it initiates a deregistration request DREG_REQ message, and the activation code (Action Code) in the message is set to 0x01, indicating that it is required to enter the IDLE MODE, and the message format is defined in 802.16e.
[0131] (2) After receiving the DREG_REQ message, the SBS / PA will send a mobile terminal deregistration request (MSS DregRequest) message to its local paging controller (the PC that manages the PA), and the message carries MSS ID, BSID, PG_ID, idle Mode retention information (Idle Mode Retain Information), etc.
[0132] (3) After the local PC receives the...
