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...

Abstract

The invention provides a method for the terminal in the wireless LAN entering the leisure mode, it includes following steps: a. the moving terminal sends the requirement for entering the idle mode to the base station BS / paging agent PA; b. said BS / PA response the requirement sent by the moving terminal, the drop point PC determines to allow the moving terminal entering the leisure mode, and informs the data path to release the link of moving terminal; c. after the link of moving terminal is released, BS / PA send deleted registration message which shows the location is refreshed successfully to the moving terminal; d. BS / PA sends the confirmed messages to the further agent FA, and the FA sends the message to the drop point paging controller PC / location register LR, and saves the context ofmoving terminal to refresh the data. The invention increases the integrality and stability for the moving terminal entering the idle mode.

Description

technical field [0001] The invention relates to wireless metropolitan area network technology, specifically, a method for a terminal in a wireless metropolitan area network to enter an idle mode. Background technique [0002] The idle mode is a terminal working mode in the mobile broadband wireless access system defined by the IEEE 802.16e standard. In idle mode, the mobile terminal (MSS) can move within a set area, receive downlink broadcast service messages every certain period, and notify the MSS through broadcast messages whether there is downlink service to send, and the MSS does not need to In the roaming cell, register with the BS of this cell. At the same time, when the MSS roams to different cells, it does not need to perform normal operation procedures such as handover, which helps to save MSS power and air interface resources. [0003] Multiple BSs can form a group, called a paging group (Paging Group). The purpose of the paging group is to form a continuous ar...
