The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an embodiment of a local timer message processing apparatus of a serving GPRS supply node (SGSN) according to the present invention.

As shown in FIG. 1, a local timer message processing apparatus of a serving GPRS supply node (SGSN) according to the present invention includes a user interface area 100 for providing a local timer message processing application program interface to a user, and a user application program. Level local library area 101 and platform device memory device area 102.

Here, the local library area 101 is the local timer initialization unit 103, the local timer registration unit 104, the local timer cancellation unit 105 is provided to the user in the form of a local library.

The local timer initialization unit 103 maintains and manages user application block identifier information used as destination information for receiving a local timer message, and the time required to receive the local timer message record 109 from the memory device area 102. In order to reduce the number of times, the process of creating and initializing the local timer record 109 in advance is performed as many as required by the user application block.

The local timer register 104 performs a procedure of storing the local timer message requested by the user application block in the form of a local timer message record 109 in the memory device area.

The local timer canceling unit 105 performs a procedure of canceling a timer signal message registered in the local timer message record 109 of the memory device area 102.

The local timer manager 106 operates in the form of a daemon thread that manages the local timer record 109, and is executed as a high-level daemon thread by the timer initializer 103, by monitoring the "tmval" value of all local timer records. The time-out is determined and a time-out signal message is sent to the user application block.

On the other hand, the timer list (TimerList) 107 is for managing a pointer to the first record of the local timer message record 109, the timer tail (TimerTail) 108 is currently registered in the local timer message record 109 It serves to display the last message.

Since the local timer message record 109 is composed of a dual linked list, it has a backward (110) and a forward (116). The other fields 111 to 115 are added by the convenience of the user. Items.

That is, "111" is a time-out value (Tmval), "112" is a local timer message type (mtype), "113" is a timer message (data), "114" is a timer message size (data_len), and "115". Represents a timer identifier tmid, respectively.

As shown in FIG. 2, the local timer initialization process according to the present invention is activated by a user function block, and receives parameters such as a timer record number setting and a timer message reception block identifier at an activation time (200). Here, the setting of the number of timer records is for pre-allocating records from the memory area in order to reduce the memory allocation load in real time.

Then, it checks whether the number of records has been allocated as much as the predicted number (201) and executes the timer manager daemon thread if it has been allocated (205). After the operation is properly performed (203, 204), record allocation and initialization operations are continued until records are allocated as many as the number of timer records.

3 is a flowchart illustrating a local timer message registration process in the local timer message register 104 of the local timer message processing device of the serving GPRS supply node (SGSN) according to the present invention.

As shown in FIG. 3, the local timer message registration process according to the present invention is activated by a user function block, and receives a timer value, a timer message type, a message, a message size, and a timer identifier parameter at an activation time (300). ).

Subsequently, the local timer message registration checks whether the time-out value (tmval) 111 is -999 by accessing the message record from the timer list (TimerList) 107 to the last record (301).

As a result, if a record having a time-out value 111 of 999 exists, it is assigned to each parameter of the timer record, and a timer tail 108 is assigned to a record whose time-out value 111 satisfies -999. Set to a pointer value (303).

As a result of the check, if there is no record having the time-out value 111 of -999, an n-th timer record is generated and assigned to each parameter (302).

4 is a flowchart illustrating a process for minimizing a local timer message in a local timer message canceling unit 105 of a local timer message processing apparatus of a serving GPRS supply node (SGSN) according to the present invention.

As shown in FIG. 4, the local timer message canceling process according to the present invention is activated by the user function block, and receives a timer identifier parameter at the activation time (400).

Subsequently, in order to cancel the local timer message, the message record is accessed from the timer list 107 to search for a timer tail 108 record to determine whether a timer record having the corresponding timer identifier is found (401). .

As a result of the check, if there is a timer record having the corresponding timer identifier, the initialization operation is appropriately performed (403). If not, the timer message cancellation failure processing is performed (402).

That is, the local timer canceling unit 105 registers the initialization record deleted by the cancellation to the last node of the dual connection list of the memory device area.

5 is a flowchart illustrating a local timer message management process in the local timer message management unit 106 of the local timer message processing apparatus of the serving GPRS supply node (SGSN) according to the present invention.

As shown in FIG. 5, the local timer message management process according to the present invention is activated by the timer initialization unit 103, starting from a timer list 107, and a timer tail 108. Search for the record to find a record whose time-out value (tmval) 111 is less than zero (500), and send a time-out signal message to the timer receive block (502), and adjust the duplex structure of the record. (503).

If the time-out value 111 is greater than 1, it executes -1 and continuously monitors whether a time-out record exists (501). Accordingly, the local timer manager 106 registers the initialization record deleted by the time-out to the last node of the dual connection list of the memory device area.

That is, the present invention initializes a local timer by activating a timer manager that initializes a local timer record and manages a local timer record in the form of a daemon thread, and sets a timer to register a local message in a local timer message static or dynamic record. The local timer record managing the registered local timer message is deleted, and the deleted initialization record is registered at the last node of the dual connection list of the memory device area. Here, the timer manager monitors the time-out of the local timer message, informs the timed-out local timer message user block, deletes the time-outed and initialized record, and registers it with the last node of the dual connectivity list in the memory device area. Increasing system efficiency by reducing the number of cases of dynamically allocating memory during the timer registration procedure by initializing records deleted by local timer message termination or time-out and registering them with the last node of the dual-link list in the memory device area. And increase the reusability of records.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention can flexibly adjust the size of the local timer message at the user level, and by increasing the capacity of the memory device at a low memory cost, it is possible to manage and operate a large amount of local timer message records. In addition, the present invention has the effect of providing the level of flexibility required by the functional block as an alternative to overcome the limitation problem of the 3 to 4,000 timer resources provided by the commercial platform.
