Abstract
The invention provides a method for preventing task congestion in a VOIP (voice over internet protocols) phone through a thread pool. The method includes that: 1, a thread pool is started constructing by a phone, a preset number of threads are established in the thread pool, and each thread has a task queue; 2, a task virtual base class, including methods for executing tasks, reading tasks and writing tasks, is defined, and can store the pointers of calling classes in the phone; and each task inherits the corresponding task virtual base class; 3, when the phone is used, required tasks are established, established tasks are put into the thread pool, and are thrown to specified threads or any unoccupied general threads; if no unoccupied general thread exists, the tasks are thrown into the task queue of any general thread to be queued up; after any thread executes tasks, the tasks are called back by a callback function, and tidy ups are completed in a main thread. While the main thread of the phone is executed, some specified tasks can be executed asynchronously, and the task congestion in the VOIP phone is prevented.
Description
Technical field
The present invention relates to the technical field of communication apparatus, particularly relate to a kind of method being prevented task blocking in VOIP phone by thread pool.
Background technology
The networking telephone is also called VOIP phone, be landline telephone and the mobile phone of directly being dialed the other side by the Internet, comprise national distance and international long-distance, and rate is 10% to 20% of black phone expenses, macroscopically say and can be divided into soft phone and hardware phone.Soft phone is exactly download software on computers, then buys networking telephone card, is then conversed by headset realization and the other side's (fixed line or mobile phone); Hardware phone is relatively applicable to the use such as company, fixed telephone bar, and first want voice gateways, gateway is received on router, and another side is received on common phone, and then common phone can directly have been breathed out by network freedom.And existing in VOIP phone in can there is many tasks to be processed, conventional task is had in this task, also important task is had, then a main thread is often only had in VOIP phone, like this at main thread Processing tasks not in time, task important in phone will be caused to process timely, the experience effect of such client is just very poor, when such as user will carry out some subtasks such as download remote contact file or searching for contact persons, main thread due to now phone is busier cannot be processed in time, so just cannot long-range display contact person.
Summary of the invention
The technical problem to be solved in the present invention, is to provide a kind of method being prevented task blocking in VOIP phone by thread pool, solves because task in phone is too many, and main thread process does not come to cause the problem of task blocking in phone.
The present invention is achieved in that a kind of method being prevented task blocking in VOIP phone by thread pool, comprises the steps:
Step 1, VOIP phone start structure one thread pool, and in this thread pool, create the thread of predetermined amount, each thread has a task queue, for the queuing of task; Described thread comprises general thread and dedicated thread; This general thread is the thread that in phone, normal work to do all can share; This dedicated thread is the thread that in phone, vital task is used, for preventing the obstruction of vital task;
Step 2, define a task virtual base class, this task virtual base class comprises: execute the task, the method for reading task, writing task, and can preserve in phone the pointer calling class; In described phone, each task is all inherited from this task virtual base class;
When step 3, VOIP phone use, task needed for establishment, each task created is put into described thread pool, and thread pool throws to the general thread of dedicated thread or any free time, if leisureless general thread, then throw away at random in the task queue of any general thread and rank; After the complete task of any thread execution, adjusted back by call back function, in the main thread of phone, complete round-off work; Described call back function is the class using thread pool to execute the task, to realize the complete rear readjustment of tasks carrying.。
Further, described normal work to do comprises: various remote address book downloading task, ring signal file downloading task, file read-write task or search mission.
Further, described vital task comprises: LDAP contact person obtains task or local linkages people search mission.
Tool of the present invention has the following advantages:
1, the main thread of VOIP phone of the present invention is while operation, can some particular task of asynchronous operation, does not also affect main thread and runs.
2, by the application of dedicated thread in thread pool, specific vital task is not blocked.
3, use simply, only need succession one task virtual base class, realize call back function.
4, clear in structure, realize simple, be beneficial to expansion, any particular task only need inherit task virtual base class, realizes its specific method.
Accompanying drawing explanation
Fig. 1 is method flow schematic diagram of the present invention.
Embodiment
Refer to shown in Fig. 1, the present invention is a kind of method being prevented task blocking in VOIP phone by thread pool, comprises the steps:
Step 1, VOIP phone start structure one thread pool, and in this thread pool, create the thread of predetermined amount, each thread has a task queue, for the queuing of task; Described thread comprises general thread and dedicated thread; This general thread is the thread that in phone, normal work to do all can share; This dedicated thread is the thread that in phone, vital task is used, for preventing the obstruction of vital task;
Step 2, define a task virtual base class, this task virtual base class comprises: execute the task, the method for reading task (as search mission, downloading task etc.), writing task (as to server up transfer file task), and can preserve in phone the pointer calling class; In described phone, each task is all inherited from this task virtual base class; And the method realized in task virtual base class;
When step 3, VOIP phone use, task needed for establishment, each task created is put into described thread pool, and thread pool throws to the general thread of dedicated thread or any free time, if leisureless general thread, then throw away at random in the task queue of any general thread and rank; After the complete task of any thread execution, adjusted back by call back function, in the main thread of phone, complete round-off work; Described call back function is the class using thread pool to execute the task, and this Similar integral has the virtual base class of a pure virtual function (call back function), to realize the complete rear readjustment of tasks carrying.
In the present invention, described normal work to do comprises: various remote address book downloading task, ring signal file downloading task, file read-write task or search mission etc.Described vital task comprises: telephone directory LDAP contact person obtains task or local linkages people search mission etc. (can be self-defined according to concrete importance).
In a word, the main thread of VOIP phone of the present invention, can some particular task of asynchronous operation while operation, does not also affect main thread and runs.By the application of dedicated thread in thread pool, do not block specific vital task.And the present invention uses simply, only need succession one task virtual base class, realize call back function; Clear in structure of the present invention in addition, realize simple, be beneficial to expansion, any particular task only need inherit task virtual base class, realizes its specific method.
Although the foregoing describe the specific embodiment of the present invention; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present invention; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present invention and change, should be encompassed in scope that claim of the present invention protects.
