Embodiment 1

[0035] Schematic diagram of the network-initiated location update process.

[0036] Referring to Figure 3, the process description is as follows:

[0037] (1) A certain terminal is already in idle mode, and the terminal has not updated its location for a period of time. The paging controller managing the terminal will construct a paging notification message (location update, start paging), and send it to the terminal to which the terminal belongs. All base stations under the paging group require the terminal to perform a location update process;

[0038] (2) After the base station receives the paging notification message, it judges that a paging process needs to be initiated, constructs a paging broadcast message (MOB-PAG-ADV) according to the definition of the IEEE802.16e standard, and sends it over the air;

[0039] (3) The terminal receives the paging broadcast message, and sends a RNG-REQ message to the base station when it knows that location update is required according...

Embodiment 2

[0049] Schematic diagram of the flow of the terminal exiting the idle mode.

[0050] With reference to the accompanying drawing 4, the process description is as follows:

[0051] (1) The application layer has data to send to a certain terminal in idle mode. The home agent sends these data to the access gateway where the terminal is currently located.

[0052] (2) The gateway requests the paging controller to which the terminal belongs to acquire relevant information of the terminal.

[0053] (3)-(4) The paging controller returns some information of the terminal to the gateway, and at the same time sends a paging notification message to all base stations in the paging group where the terminal belongs, requesting to start paging broadcast.

[0054] (5) After receiving the paging notification message, the base station sends an air interface paging broadcast message.

[0055] (6) The terminal learns that there is data paged to itself according to the indication in the paging br...

Abstract

The invention discloses a method to improve system performance in wireless access system of mobile broad band, which is invented to solve the problem that the base station which does not receive the response from terminal can not terminate to transmit the messages of seeking broadcast. Said method includes: accessing network sends the messages of seeking broadcast to require the terminal to act following the requirement, and the terminal begins according to the requirement of network, after the network receives the response, and it can inform the relative node to stop transmitting broadcast messages to reduce the occupancy of air source and system source, and improves the availability factor of wireless source and system source, and at the same time, the chance which is chosen in reason can ensure the success rate of seeking.

Description

technical field [0001] The invention relates to a method for reducing invalid occupation of wireless resources and system resources in a mobile broadband wireless access system. Background technique [0002] The IEEE802.16e standard is a broadband wireless access standard formulated by the IEEE standard organization. Compared with the IEEE802.16-2004 standard, 802.16e adds a lot of support for terminal mobility. Such as switching and power saving mechanisms. [0003] Idle mode is a very important power saving mechanism in 802.16e systems. In order to support paging of terminals in idle mode, the protocol proposes the concept of paging area. Multiple BSs are divided into one paging area, and overlapping between paging areas is allowed. Multiple paging areas are managed by one paging controller (PC). As shown in Figure 1, BS0 and BS1 belong to paging group A, BS1 and BS2 belong to paging group B, PC0 manages paging group A, PC1 manages paging group B, PC0 and PC1 are respe...
