Description

The method of timer duration is set in communication equipment

Technical field

The present invention relates to the control to the communication system calling, specifically, relate to the method for in the communication equipment that adopts the timer agreement, the timer duration of protection call state being reseted.

Background technology

In the communication technology, set up calling out accurately and quickly is the user to one of basic demand of telecom operators. But, in the process of call setup, because the many reasons such as transmission fault, data collocation error or user's misoperation can cause calling normally not carry out. Be in for a long time unusually if call out, then can cause system mode machine and the communication resource to be in for a long time locking state, thereby reduce the operational efficiency of communication system.

For fear of this situation, in the ECMA-143 agreement of European Computer Manufacture's Association (ECMA) suggestion, stipulated that some timers protect call state. These timer operated by rotary motion are in router or switch. These timers of ECMA-143 agreement defined are divided into two classes according to the definition of its duration; one class is the timer of having stipulated duration, for example is used for the timer T302 that " overlapping reception " state is protected and the timer T304 that " overlapping transmission " state is protected. Another kind of is the timer of regulation duration not, the timer T301 that for example " calling is submitted " state is protected.

On the other hand, stipulated that the timer of duration also is divided into two classes, the duration of a class timer determines, timer T304 above-mentioned for example, and the ECMA-143 agreement stipulates that its duration is 20 seconds. The duration of another kind of timer has then been stipulated a scope, timer T302 for example, and the ECMA-143 agreement stipulates that its duration scope is 14 to 16 seconds.

Effect and the duration thereof of 11 kinds of timers of ECMA-143 agreement regulation have been listed in the table 1.

The timer of table 1.ECMA-143 agreement regulation

The timer name	Effect	Regulation duration (second)
			The T301 timer	" calling is submitted " state is protected. This timer starts after Calling Side is received the ALERTING message that callee side sends, and is used for the time that CONNECT message is waited in restriction.	Nothing
The T302 timer	" overlapping reception " state is protected. This timer starts when sending SETUP ACKNOWLEDGE message, restarts after receiving INFORMATION message, is used for the time that dialing is waited in restriction.	14～16
			The T303 timer	" calling out initial " state is protected. This timer starts after sending SETUP message, is used for the time that SETUP ACKNOWLEDGE/CALL PROCEEDING/ALERTING/ CONNECT/RELEASE COMPLETE message is waited in restriction.	4～6
The T304 timer	" overlapping transmission " state is protected. This timer starts when receiving SETUP ACKNOWLEDGE message (perhaps sending INFORMATIONG message). Be used for restriction and wait for the time of CALL PROCEEDING/ALERTING/CONNECT message.	20
			The T305 timer	" request of taking out stitches " state is protected. This timer starts when sending DISCONNECT message, is used for the time that RELEASE or DISCONNECT message are waited in restriction.	4～30
The T308 timer	" releasing request " state is protected. This timer starts when sending RELEASE message, is used for the time that RELEASE or RELEASE COMPLETE message are waited in restriction.	4～6

The T309 timer	Calling to built vertical connection when link failure is protected. This timer starts when the QSIG data link layer breaks down, and is used for delay protection is carried out in the calling that has connected.	90
			The T310 timer	" exhalation process " state is protected. This timer starts when receiving CALL PROCEEDING message, is used for the time that ALERTING/ CONNECT/DISCONNECT/RELEASE message is waited in restriction.	Nothing
The T313 timer	" connection request " state is protected. This timer starts when sending CONNECT message, is used for the time that CONNECT ACKNOWLEDGE message is waited in restriction.	4～6
			The T316 timer	" restarting " program is protected. This timer starts when sending RESTART message, is used for the time that RESTART ACKNOWLEDGE message is waited in restriction.	120
The T322 timer	" status poll " program is protected. This timer starts when sending STATUS ENQUIRY message, is used for the time that STATUS message is waited in restriction.	4～6

Timer under the ECMA-143 agreement can be classified as follows by above-mentioned by table 1:

1. stipulate the timer of duration scope: T302, T303, T306, T313, T322;

2. stipulate the timer of duration value: T304, T305, T309, T316;

3. do not stipulate the timer of duration: T301, T310.

For the timer that does not have the clear duration, i.e. timer T301 and T310, each manufacturer of the same trade just can oneself determine the duration of these timers. For example, be generally will be about 30 seconds to the requirement of T310 timer, but in some business, will be no less than 110 seconds. When in this case, different manufacturers realizes T310 in the equipment of its production very large difference may be arranged. Therefore, will produce the problem that can not cooperatively interact during these device intercommunicatings of different manufacturers.

On the other hand, in actual applications, because user's conditions of demand are varied, therefore the duration of timer also had different requirements, these requirements tend to not be inconsistent or exceed with the setting of agreement the scope of agreement setting. Therefore, the duration scope of the timer of ECMA-143 agreement regulation is relaxed in hope as much as possible. Have not yet to see the relevant report that solves this technical problem.

Summary of the invention

In view of the above problems, purpose of the present invention is exactly will provide in a kind of communication equipment of the timer agreement adopting ECMA-143 agreement and so on to allow the user to reset the method for timer duration value by terminal, make the user that larger range of choice be arranged when selecting the duration of timer, to satisfy the special calling demand of oneself.

A further object of the invention is the method for the timer duration value being reseted by above-mentioned, can solve in real time the matching problem of intercommunication between the equipment of each manufacturer.

According to a first aspect of the invention, provide a kind of method that timer duration value in the communication equipment that adopts the timer agreement is arranged. The method comprises: the duration scope that presets each timer of this timer agreement defined in the communication equipment that adopts the timer agreement; The user arranges the duration of each timer by the user's configuration interface in the communication equipment; Communication equipment judges that timer duration that the user arranges is whether in the timer duration span that has arranged; If the timer duration that judged result is the user to be arranged is in the timer duration span that has arranged, then this communication equipment is accepted the timer duration that this user arranges.

In said method, above-mentioned communication equipment can be router or the switch in the communication system.

In said method, also comprise, the default value of all timer durations is set, when the user does not arrange certain timer duration, then to the default duration of this set timer in above-mentioned communication equipment.

Description of drawings

Fig. 1 is the flow chart of an embodiment of the inventive method.

Embodiments of the invention

With reference to Fig. 1, the embodiment of the inventive method is described as example take the router that adopts the ECMA-143 agreement.

According to a kind of embodiment of the present invention, user's configuration interface in the router that adopts the ECMA-143 agreement has increased the timer command processing module of ECMA-143 agreement, and has in this user's configuration interface for the user's configuration order collection that arranges and inquire about the ECMA-143 timer duration. The user, arranges and inquires about all or some of them timer of ECMA-143 agreement defined by these user's configuration orders at set user's configuration interface.

Specifically, in this embodiment of the present invention, the command format that the timer command processing module of ECMA-143 agreement at first will be judged input whether with the format match that has defined (concrete form is referring to the set timer command component of back), HELP command whether, or complete order is set. If inconsistent with the command format that defines, just point out mistake; If HELP command is just exported corresponding timer help information; If complete order is set, and the duration of input is in the timer allowed band, with regard to the timer duration in the change system.

The configuration interface that is connected to router by terminal PC as the user is inputted for the order line of configuration or the interface input by NML and is used for arranging or when obtaining the message of timer relevant information, after these order lines or message process control mouthful order or NML carry out preliminary treatment, deliver to this timer command processing module and process, the function that will realize with these order lines of final realization or message.

The below illustrates the processing procedure of command processing module. For example, for order line isdn qsig-timer T301 duration value, if isdn, qsig-timer, these three key order words of T301 are inputed by mistake, perhaps duration value is not that 1200s, minimum permission duration are in the scope of 30s at the maximum permission duration of system default T301, and then command processing module all will be pointed out mistake to the user; If is input isdn qsig-timer? the timer title of just pointing out all ECMA-143 to arrange is such as T301, T302 etc.; If is input isdn qsig-timer T301? just point out the maximum of timer duration information-comprise T301 to allow that duration is 1200s, minimum to allow duration be 30s, default value is 180s; If correctly inputted isdn qsig-timer T301 40, the duration that system just will adjust this timer is 40s.

All orders that timer duration is set all are effective to each isdn interface, therefore require the user to input under interface configuration mode; On the other hand, the timer command processing module is with the order of command set for inputting under global schema of all inquiry timer durations, and is so that these order overall situations effectively, namely all effective under all user models.

Simultaneously, the present invention's duration scope to all timers of ECMA-143 agreement defined on the router that adopts the ECMA-143 agreement is expanded, to satisfy the needs of different user. Specifically, the present invention is in conjunction with the ECMA-143 agreement, keeps the relatively clearer and more definite and part clearly of its definition, and for example the former agreement setting with T304, T309 and T316 is set as default value; The part too narrow to the duration value scope of ambiguity in definition in the agreement or definition done more clear, wider adjustment in conjunction with the practical experience that adopts other timer agreement operation on the other hand. And, according to the present invention, in the communication equipment that adopts the ECMA-143 agreement, all timers all are provided with default value, so that the equipment that each manufacturer is produced has intercommunity.

Specifically, when the user will arrange and inquire about the timer of ECMA-143 agreement defined, at the enterprising access customer configuration interface of terminal. Then under interface modes, input successively user's configuration order collection.

User's configuration order collection comprises that the user inquires about the order that timer allows duration scope and default value, the order etc. that the user resets the order of timer duration and inquires about the current duration of all timers. Also can be only to comprise that the user arranges the order of timer duration. In this case, the session window that can provide the user to reset timer duration in user's configuration interface is directly inputted required timer duration in the mode of man-machine interaction by the user.

Router is after receiving these orders, at first will show help information at user's configuration interface, the minimum and maximum permission duration of example each timer that in router, sets in advance as explained above, be the permission duration scope of each timer, and the default value of each timer duration etc.

Duration for user's input changes the duration value of ordering or inputting, and router will judge whether it has exceeded the scope to the permission duration of corresponding timer defined, namely the duration scope of each timer. If exceeded, it is unsuccessful that then reminding user is reseted the order of duration, need to re-enter duration and change order. On the other hand, if the user skips current set timer, the router default value of timer of will having thought user selection then.

When the duration that comprises in the duration change order of user's input set value in the scope that router allows, this router confirmed that namely the user is to the change of timer duration.

The below illustrates present embodiment reseting each timer duration with the example of concrete numerical value.

At first, in the router that adopts the ECMA-143 agreement, preset duration allowed band and the default value of each timer. Table 2 has been listed the comparison of each timer duration of stipulating with the ECMA-143 agreement.
