Problems solved by technology

[0011] 3. When the system device starts running, one or more AAL2 channels need to be selected for use, but the local device does not know whether the corresponding AAL2 channel is configured on the other device, and whether these AAL2 channels are available on the other device. Make the right choice, it is possible to fail when applying for AAL2 channel resources

Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] In order to automatically maintain a reasonable availability for the AAL2 channel in a timely manner, the management unit needs to detect whether all AAL2 channels have failed in real time. Set it to the fault state and trigger the blocking process. After the blocking process is completed, the network elements of both parties can no longer use the failed AAL2 channel. The status flag after the occlusion process is completed is shown in Figure 3. When detecting that a certain AAL2 channel recovers from a fault, the management unit will set the fault status flag of this AAL2 channel to a non-failure state. At this time, it is also necessary to check the manual status flag. Initiate the unblocking operation. After the unblocking operation is successful, the AAL2 channel is set to the local unblocking state locally, and is set to the remot...

Abstract

A method for managing availability of channel for adaptive layer service in asynchronous transmission mode includes adding an availability management unit of AAL2 channel in RNC and setting fault state flag and manual state flag on each AAL2 channel, detecting whether there is hardware fault or software fault on AAAL2 channel or not in real time by management unit, executing an unblocking operation and detecting state flag of AAL2 channel on set time when operation of device is stared, executing relevant blocking / unblocking operation and revising relevant state flag for lifting off fault AAL2 resource in system timely.

Description

technical field [0001] The present invention relates to a method for managing the availability of communication resources, in particular to a core network (Core Network) (hereinafter referred to as CN), radio network controller (Radio Network Controller) (hereinafter referred to as RNC), and base station NodeB and other network element equipment such as asynchronous transfer mode adaptation layer 2 service (ATMAdaptation Layer 2) (hereinafter referred to as AAL2) channel Resource availability management methods. Background technique [0002] When the third-generation mobile communication system uses ATM technology as the ground transmission bearer, the Iu-cs interface between CN and RNC, the Iub interface between RNC and NodeB, and the Iur interface between RNCs all use AAL2 channels to transmit voice and data . [0003] One or more AAL2 channels must be configured between the two network elements that send and receive data. Each AAL2 channel is identified by a PathId. Eac...
