Description
Technical field
The present invention relates to the communications field, particularly communication equipment internal module information interaction technology.
Background technology
Along with the continuous intensification of the level of informatization, the mankind are more and more higher to the requirement of capacity, speed, quality and the type service of communication.The popularizing of personal computer and Internet, data service have brought revolutionary variation with the develop rapidly of E-mail communication and various broadband access technologys to communication network and communication equipment.
In order to satisfy more and more higher communicating requirement, communication equipment becomes and becomes increasingly complex, and the function that requires to realize also gets more and more, and makes and must adopt standardization, modular development scheme.The a large amount of different integrated circuit boards of various tasks that use of the developer of communication equipment constitute each communication equipment module, are built into complete facility communication system by these modules with difference in functionality again, can reduce the required cost of the exclusive framework of exploitation thus in a large number.So adopt standardized module, shared module than the output that is easier to reach certain, cost reduces naturally.
This shows that communication equipment is actually by many relatively independent integrated circuit boards or module and constitutes, subsystem of each self-forming is combined into a complete system.Therefore, for whole system, utilizing the effective cooperation between a plurality of subsystems is the key of finishing systemic-function.In addition, be the main aspect that cooperatively interacts alternately between subsystem.
Can better to divide the work between each subsystem and cooperation in the system in order making, in modern software design procedure, generally to adopt message processing facility to reduce the degree of coupling between each subsystem greatly, and become important way mutual between subsystem.This information interaction is to be handled by the reception of the transmission of message and message to realize.
A kind of information in the communication equipment of prior art sends hairdo as shown in Figure 1, and this mode has adopted timer, and needs the response of message sink module.
In step 101, the module that module 2 sends as information sends message to module 1.
In step 102, module 2 starts timer when message sends.
In step 103, if module 2 is received the response message that module 1 is returned, then change step 104 over to, otherwise, handle by Fig. 2 or mode shown in Figure 3.
In step 104, module 2 timeing closing devices, and this information of mark sends successfully.
In the step 103 of above-mentioned information sender formula, if up to the timer expiry of module 2, still do not receive the response message that module 1 is returned, at this moment, the transmission of information can be handled by mode shown in Figure 2.
Step 201 is identical with step 101 and step 102 with step 202.
In step 203, up to timer expiry,, then return step 201, and move in circles, till module 1 response if module 2 is not received response message yet.
In addition, if, in step 103,, do not receive the situation of the response message that module 1 is returned yet, can also handle by mode shown in Figure 3 up to timer expiry by information sender formula shown in Figure 1.
Step 301 is identical with step 101 and step 102 with step 302.
In step 303, during timer expiry, module 2 is not received response message yet, and then this information of mark sends failure, stops to handle.
Another kind of information sender formula in the communication equipment as shown in Figure 4, this mode does not adopt timer, does not need the response of module 1 yet.
Step 401 is with step 201, and module 2 directly sends message to module 1.
In step 402, module 2 is after sending message, and just directly label information sends successfully.
In actual applications, there is following problem in such scheme: there is waste in system resource, and can influence the reliability of system equipment, and information transmits the losing probability height.
Cause the main cause of this situation to be, because, can make the information that can't receive in a large number in system equipment, send if the module of message pick-up starts when causing unusually normally moving, waste system resource, for example module 2 starts situations such as unusual;
Because when the module of information transmission need provide information to a plurality of modules, the also mode of wait-for-response that resends that adopts, can be because the serious waste of resource that mistake causes of a subsystem, the serious paralysis that may cause whole system, thereby influence the performance of system equipment, for example, information sender formula as shown in Figure 2;
Because if the module that information sends adopts overtime stopping to handle, for example, information sender formula as shown in Figure 3, mark sends successfully in case perhaps adopt information to send just, for example, and information sender formula as shown in Figure 4, when the module of message pick-up can't normally receive is because status error when causing, even the recovering state of the module of message pick-up is normal so, also can't receive and send information, cause information dropout.

The invention provides interactive method between modules in a kind of communication equipment,, will be called service module, be called client's module as information receiver's module as the module of information transmitter at this.
In this equipment, when service module resets, can trigger corresponding each client's module and all reset.Client's module sends the request message of appointed information that pulls subscription to service module when resetting back or startup, if do not receive the response message from this service module after presetting duration, then retransmit this request message.
Service module is set up the corresponding relation of this client's module and its ordered appointed information behind the request message of receiving from client's module, and returns response message to this client's module.When subscribed appointed information changed, service module just sent corresponding notification message according to this corresponding relation to client's module, and sending the directly successful information of mark transmission of back, need not to wait for that this client's module acknowledges receipt of this notification message.Because service module is that the information that client's module is subscribed to is sent to this client's module by the disposable mode that need not to respond, therefore, even certain client's module can't normally be moved, can not cause service module to carry out transmission flow repeatedly yet, thereby cause hanging of whole system.And, therefore prevented the invalid information in the system because service module has been set up the corresponding relation of client's module and its ordered information, and saved system resource, improved systematic function.
Wherein, the information of service module can be subscribed to by a plurality of client's modules, and service module when this information changes, sends corresponding notification message to all client's modules of having subscribed to according to subscribing to the corresponding relation that forms.
Intermodule information subscribing mode as shown in Figure 5 in the communication equipment of first embodiment of the invention.Because the startup stage of unusually often the occurring in of module, therefore, the subscribe request that client's module sends during startup need adopt retransmission mechanism to receive this request to guarantee service module.
In step 501, client's module 1 sends subscribe request to service module when starting.
In step 502, client's module 1 starts timer when sending subscribe request.
In step 503,,, and change step 505 over to then according to the corresponding relation of this this client's module 1 of request record with appointed information if service module has been received the subscribe request of 1 pair of appointed information of client's module.
In step 504, if the timer timing of client's module 1 arrives, do not receive the subscription response message of service module yet, then restart timer, turn back to step 501, wait-for-response.
In step 505, service module returns subscription response for client's module 1, notifies client's module 1 to subscribe to successfully.
In step 506, client's module 1 receives and subscribes to successful notice that the timeing closing device has been finished the subscription of appointed information.
This programme is that information subscribing with client's module is an example, and for the information subscribing that a plurality of client's modules are carried out, each client's module can be carried out identical operations.
After appointed information was subscribed to successfully, in a single day the appointed information in the service module had change, then can send a notification message to client's module of having subscribed to this information, and its send mode as shown in Figure 6.
In step 601, subscribed information has change in the service module.
In step 602, service module is searched the subscribing relationship table, finds all client's module lists that subscribing relationship is arranged with this modification information, finds client's module 1 and client's module 2.
In step 603, service module sends the notification message of this information-change according to this unidirectional client's module 1.
In step 604, service module sends the notification message of this information-change according to this unidirectional client's module 2.After subscription is finished, whole system has entered stable state, the ordered information of client's module that service module sends is difficult for losing, therefore, thisly send a request message when restarting and require response, information sends the interactive method between modules do not require response, reduced the probability of information dropout in the system equipment, simultaneously also avoided causing hanging of whole system unusually, saved system resource, improved systematic function owing to the startup of individual customer module.
Intermodule information subscribing mode as shown in Figure 7 in the communication equipment of second embodiment of the invention.Because service module is restarted, and has caused that client's module 1,2 resets, make client's module 1,2 all will initiate again to subscribe to, wherein, initiate to subscribe to as shown in the drawing after client's module 2 resets again.
In step 701, client's module 2 presets the thresholding number of times that sends subscribe request.
In step 702, client's module 2 is to the subscribe request of service module transmission appointed information, and wait-for-response.If do not receive the response message of service module, then repeating step 702.
In step 703, when the subscribe request transmission number of times of this appointed information reached the thresholding number of times that presets, client's module 2 was not received the response message of service module yet, then stops this subscribe request.Because repeatedly retransmit not response, client's module 2 judges that serious fault has taken place service module, and normal service can not be provided, and there is no need to retransmit again.Entire equipment resets again after generally getting rid of the fault of service module by the attendant, and each client's module is subscribed to trial once more.
The structure of module as shown in Figure 8 in the communication equipment of third embodiment of the invention.Comprise the client's module as the information receiver in this equipment as the service module of information transmitter and one (or a plurality of).
Specifically, comprise in client's module: be used to send message transmitting element, be used to receive the receiving element and the timer of message.
Wherein, the transmitting element of client's module sends the request message of appointed information that pulls subscription to service module after this client's module resets, and starts the timer in it; The receiving element of client's module then when the response message of receiving this request message, stops this timer; The function of this timer is the transmitting element re-transmission request message in regularly overtime this client's module of back indication.
Service module then comprises: be used to send message transmitting element, be used to receive message receiving element, be used to preserve client's module and its ordered appointed information corresponding relation memory cell and be used to judge whether subscribed appointed information the judging unit that changes has taken place.
Wherein, the receiving element of service module is set up the corresponding relation of the appointed information of this client's module and its subscription behind the request message of receiving from client's module, and this corresponding relation is kept in the memory cell; And send response message to client's module by transmitting element; When judging unit judged that variation has taken place subscribed appointed information, the indication transmitting element sent a notification message to client's module of having subscribed to this appointed information according to the corresponding relation in the memory cell.
According to two kinds of modular structures of above-mentioned communication equipment, persons skilled in the art are appreciated that these two kinds of structures can be present in the module simultaneously, make this module possess the function of service module and client's module simultaneously.
