This invention can make wireless communication system exploration and maintenance for convent tracing and process between each system and modules interface signals and multiple tasks.
Description
Technical Field
The present invention relates to a system and a method for tracing and processing protocol signaling (message) between subsystems and between modules in a mobile communication system, a system and a method for tracing and processing protocol signaling between specific function interfaces in a base station subsystem BSS and a switching subsystem MSS in a mobile communication system, and particularly to an implementation and a method for task management in a case of simultaneously setting multiple tasks in broadband wireless access (hereinafter referred to as BWA).
Background
A typical mobile communication system generally comprises a switching subsystem MSS, a base station subsystem BSS and a mobile station subsystem MS. The interaction between the systems is mainly accomplished by signaling information, and the BWA mobile switching system is taken as an example in the following.
There are several important interfaces in the BWA mobile communication system: an air interface R1 interface between the MS and the base station; r8 interface between BSSs; r6 interface between BSS and ASN GW (access network gateway); r3 interface between ASNGW and CSN (core network), etc.
The subsystems of the BWA mobile communication system transfer message signaling between these interfaces, and coordinate with each other, thereby implementing various functions of the mobile communication system. Whether the signaling message transmission between these interfaces is accurate and timely will affect the realization of the communication system function and the performance. Especially when a plurality of tasks need to be tracked simultaneously, if a convenient and effective method can manage and distribute the signaling messages among the tasks, the signaling tracking of the multiple tasks can be realized more conveniently and practically.
Meanwhile, when the system needs to set multiple tasks (for example, multiple clients simultaneously set one tracking task, one client simultaneously sets multiple tracking tasks, a combination thereof, and the like), a task pool is needed to create various different tasks for identification and processing, and the tasks are distributed and processed when corresponding task messages arrive.
In the prior art, the invention patent application "tracking of signaling messages" (application No. 99809744.6, published: 9/12/2001, published: 1313019a) uses a tracking copy, for one or several mobile users, of all the signaling messages related to this user. The problems of the method are that: since one service (conversation) process of one user often involves a plurality of interfaces, but only involves a small part of signaling messages of the interfaces, when the messages of a specific interface are tracked, the signaling messages of other interfaces which are irrelevant to the specific interface have to be tracked at the same time; and the specific message in the interface is related to a specific service, if the tracking is performed by adopting a mode of a designated user, when the user does not realize a certain service, the message related to the service cannot be tracked. This application only tracks one or more mobile users and not the signalling to a particular interface or to a Base Transceiver Station (BTS) or a certain cell of a BTS.
In the prior art, the invention patent application "mobile communication network protocol signaling analysis system and method" (application number: CN200310101812, published: 9/2004/15/published: CN1529447A) discloses a mobile communication network protocol signaling analysis system and method, the system includes: one or more signaling messages, a trace task agent, one or more signaling message trace backgrounds; the tracking task agent receives the task of the signaling message tracking background and sends a signaling message collecting instruction to each interface module or service module according to the task; and meanwhile, receiving signaling message data sent by a signaling message collector, and distributing the signaling message data to a signaling message tracking background. This patent only tracks for one or more collection sources and cannot track for one collection source the signaling of multiple types (such as a particular interface or for a base transceiver station BTS or a certain cell of a BTS) of tasks and any combination thereof.

Detailed Description
One implementation of the present invention is described in more detail below with reference to the accompanying drawings.
The present invention will be described in detail below by taking the management of a signaling trace task in a BWA system as an example.
As shown in fig. 1, the signaling trace in the BWA system is composed of three parts, namely, a task source, a task pool, and a collector. The task pool is responsible for creating, maintaining and deleting tasks of the task pool; the task source is responsible for initiating various tasks and for displaying the report signaling; the collector is responsible for filtering and reporting signaling tasks. Since the collectors are distributed on different boards and modules, the mapping relationship between the interfaces and the collectors needs to be stored in the task pool, so that different traces of the task sources can be forwarded to the corresponding collectors.
In BWA, tracking types are classified into BTS (base transceiver station) specific tracking, CELL specific tracking, BSID specific tracking, IMSI specific tracking (international mobile subscriber identity) and the like (but not limited to the above tracking types) in BWA according to a tracking range. Each trace has a corresponding type identifier; each task source has a corresponding task source identifier.
When the invention is implemented, firstly, two attributes are set for each task: and the type identification and the task source identification which uniquely distinguish the tracking type. The invention uses the system tracking type as the type identification for distinguishing the task pool, and simultaneously records the task source identification of the task.
Setting task pools according to task types, wherein each task pool corresponds to one tracking type; when a user selects a certain type of tracking (single selection or multiple selection), the task pool sends task requests to corresponding collectors according to the interface collector mapping table, when the collectors respond successfully, the tracking tasks are added to the corresponding task pool, and task source identifiers of the tasks are recorded. The specific creation process is as follows.
As shown in fig. 2, the method comprises the following steps:
s21, selecting the task type to be tracked by the task source, and initiating a tracking task;
s22, the task pool receives the tracking request, checks whether the task already exists in the task pool, if not, sends a request to the collector S221; otherwise, go to S25;
s23, the collector receives the request, sets the collection interface mark and sends the response message to the task pool;
s24, whether the task tracking receives a successful response or not, if the response is successful, the tracking task is added in the task pool and the task source is identified S241; if the response fails, directly returning to the task source to track the failure, and ending the task.
S25, adding a task source mark of the tracking task; and adding 1 to the task source counter, directly sending a task response success by the task pool, and ending the task.
The invention can be realized without setting a mark for the tracking task type according to the requirement.
As shown in fig. 3, when a task source selects to stop a certain type of task tracking, the specific steps are as follows:
s31, selecting a task source to stop the tracking task, and initiating the tracking stopping task;
s32, the task pool receives the request for stopping tracking, checks whether the task source counter of the tracking task in the task pool is more than 1, if yes, executes S33; otherwise, a stop tracking request is sent to the collector, followed by execution of S34;
s33, the task pool sends a response message to the task source, deletes the corresponding task source identification, and simultaneously decrements 1 for the task source counter to end;
s34, the collector receives the request for stopping tracking, sets the mark for stopping tracking and sends response message to the task pool;
s35, the task pool receives the response of stopping tracking, if the response is successful, the tracking task is deleted in the task pool S351, the response is sent to the task source S352, and meanwhile, the task source counter is decremented by 1; if the response fails, the task source is directly returned to stop the tracking failure, and the process ends S353.
Description of the drawings: stop, start are for the task source; the establishment and deletion are performed for the task pool.
When the collector finds that there is a signaling report in the tracking process, as shown in fig. 4, the following processing is performed:
s41, the collector reports the signaling message;
s42, the task pool searches the task source identification of the current tracking task in the task pool;
s43, traversing the task pool S42 to inquire the task source in the result;
s44, sending a report signaling to the task source;
s45, task pool determines whether traversal is over? If the completion, then finish; otherwise to S46;
and S46, acquiring next task source information.
The invention overcomes the defect that the prior art can only track the signaling message of the appointed mobile user, not only can track the signaling message of the appointed mobile user (such as the appointed IMSI tracking), but also can track the signaling message of the appointed interface according to the scope domain (such as the appointed BTS, the appointed CELL, the appointed BSID tracking and the like), and can simultaneously realize the multitask tracking according to any combination of the user and the scope domain; the method can realize that a plurality of clients simultaneously set one tracking task, one client simultaneously sets a plurality of tracking tasks, can also realize the combination of a plurality of tracking tasks of a plurality of clients and the like, and overcomes the defect that only one task can be tracked at a time. In addition, the multitask management of the present invention is not limited to the signaling collector, and the method is applicable to any other functional device or module that can initiate multiple tasks.
The present invention has been successfully applied to IS95, CDMA1X, CDMA2000, BWA, etc. The invention is stable and reliable in the systems, has good portability, is one of the representatives for realizing multi-task management, and has great reference significance for the research and development of other similar functions.
