Problems solved by technology

In another case, when the MS's foreign agent (FA: Foreign Agent) receives the MS's forward data packet, the FA will notify the PC / LR to perform paging, but when the PC / LR tries the predefined maximum If the number of paging times but still does not receive the ranging request message from the MS, it also means that the MS is lost
[0020] When the PC / LR learns that the MS is turned off or the MS is lost, the PC / LR will delete all the reserved information of the MS in idle mode, but the MS’s anchor point SFA may still retain the QoS information of the MS user (including Subscirber QoS Profile and related policies, etc.), because the anchor SFA of the MS does not know that the MS is powered off or lost
[0021] MS shutdown and loss both mean that the MS leaves the network. For MSs that have left the network, it is undoubtedly a waste of resources to retain their QoS configuration and policy information on the anchor SFA.

Embodiment 1

[0047] When the network side finds that the MS in IDLE mode leaves, the following steps are taken:

[0048] a. The anchor PC / LR sends a message to the anchor SFA which stores the MS's user QoS information (including QoS configuration and related policies), to inform the SFA that the user has left the network. This step includes the anchor point PC / LR directly sending the message to the anchor point SFA of the MS, and the anchor point PC / LR sending the message to the anchor point SFA of the MS through one or more relays;

[0049] b. The anchor point SFA responds to the above message, and deletes the downloaded user QoS information (such as including QoS configuration and QoS policy) of the user, and sends a response message to the anchor point PC / LR; this step also includes sending directly and through Processing flow of other relay sending.

[0050] FIG. 4 is a flow chart of the anchor PC / LR directly sending a message to the anchor SFA. In this embodiment, two messages are d...

Embodiment 2

[0059] As an alternative to the above embodiment, the anchor PC / LR may not directly send a message to the anchor SFA of the MS to notify the anchor SFA. Instead, the anchor PC / LR sends a message to a certain functional entity in the NAP (probably the FA of the MS or other entities) to notify the MS that the MS has been lost; then the functional entity notifies the MS's anchor SFA. Specifically include the following steps:

[0060] When the anchor PC / LR finds that a certain MS leaves (including MS loss and shutdown), the anchor PC / LR of the MS sends an MS exit indication (MS_Exit_Indication) message to a functional entity in the NAP (it can be the FA of the MS or Other entities), notify that the MS has been lost; the message sent by the anchor point PC / LR to the functional entity (such as FA) in this embodiment is the MS_Exit_Indication message newly defined in the present invention, and it can also pass the existing message in the current draft Add an information element (IE)...

Abstract

The provided process method when terminal off network comprises: the MS sends message to the Anchor SFA storing user QoS configuration when NS on off-line state to notify the SFA; the latter responds the message to cancel the relative user QoS message. This invention releases system resource in time, and improves system resource utility.

Description

technical field [0001] The invention relates to a wireless access system, in particular to a processing method for a terminal leaving a network in a WiMAX system. Background technique [0002] WiMax is a broadband wireless access standard and a wireless metropolitan area network technology based on the 802.16 standard, which can provide high-speed Internet-oriented connections. Different from the current 2G and 3G technologies, WiMax is a network based entirely on IP packet switching technology, and does not provide voice-oriented circuit switching technology. Therefore, to perform voice communication on the WiMax network, IP-based A form of voice service (VoIP). 802.16e is the 802.16 standard in the mobile environment. [0003] Due to the need to carry multiple services in the WiMax network, such as voice, video, HTTP, Email, etc., and various services have different requirements for the quality of service (QoS), so in the WIMAX system, it is necessary to implement suppor...
