Embodiment Construction

[0016] The gist of the present invention is to construct the time interval linked list and adopt the method of circular pointer, and use a timer to time. In the time linked list, set the fixed-point pointer and the end-point pointer. The position pointed by the fixed-point pointer is the position of the linked list where the newly added monitoring record needs to be inserted, and the position pointed by the end-point pointer is the position of the linked list that reaches the monitoring time. The timing time of the scanning timer is t, and each time the timing time of the scanning timer is up, the values ​​of the two pointers are increased by 1 and modulo N, and then the linked list pointed to by the point pointer is scanned, and all records in the linked list are considered as the monitoring time Arrived records, that is, timed out records.

[0017] Such as figure 1 As shown, in a monitoring period T, a total of N+1 linked lists of 0, 1, ..., k, ... N are constructed, and th...

Abstract

The invention relates to a method for timing monitoring control for internal memory data base in mobile communication equipment by adopting the technical measures of time gap and scanning time-sharing, which realizes increased scanning rate, decreased scanning frequentness and effectively reduced interval timer number.

Description

technical field [0001] The invention relates to a method for realizing timing monitoring of a real-time memory database, which belongs to the field of mobile communication, and in particular to timing monitoring of a memory relational database system on an embedded real-time operating system platform in a mobile communication device. Background technique [0002] In many mobile communication devices, such as the memory database of MSC, VLR or SGSN, it is necessary to regularly monitor the relevant status of users. For example, VLR needs to regularly delete expired garbage data according to user status, save memory space, and ensure that the VLR database can support the specified number of users. The MSC needs to regularly scan resources that have been occupied for a long time to check whether any resources are hung up. In the field of mobile communication, the number of users that a communication device can support is an important indicator. For a large-capacity device, if ...
