AI Technical Summary

Problems solved by technology

Whenever the process of a context ends, to search all user contexts in the memory, it is necessary to find all the contexts belonging to the request and judge whether the process has ended, which greatly wastes CPU resources and the search efficiency is very low

Embodiment Construction

[0019] The multi-target user context management method of the present invention will be described below with reference to the accompanying drawings.

[0020] In order to realize the effective management of multi-target user context, a context management method based on bidirectional circular linked list is proposed. Each context has 4 main states in the present invention: initial state, waiting state and completion state. The waiting state can be further divided into two sub-states: waiting for routing information and waiting for location information. Under normal circumstances, each user context will migrate from the initial state to the completion state through the waiting state. Under certain conditions, it can directly migrate to the completion state without going through the waiting state.

[0021] The present invention includes the following methods:

[0022] 1) The establishment method of multi-target positioning request context

[0023] 2) State transition of multi-...

Abstract

This invention relates to a user's context management method as the multi-object orientation in GMLC, which is mainly used in the gateway of the mobile location center (GMLC). The method is based on the bidirectional circular linked list structure. It includes the foundation of the multi-object users' contexts, the state transfer and the context deletion. In this invention, the several object users' contexts are linked by an unattached bidirectional circular linked list in one orientation request, and every context has its state and sign bit segment. The program control the flow through the context state. When all the context states are transferred to the completed state, the program will go through the bidirectional circular linked list, and release the contexts and their related system source in turn. This invention reduces the searching time to the context, greatly improves the management efficiency of the multi-object users' contexts, and increases the program running stability.

Description

technical field [0001] The invention relates to an upper-layer business process in a mobile location center gateway (GMLC) device, in particular to a user context management method for multi-target positioning in the GMLC. Background technique [0002] When GMLC processes the positioning request of the client, it usually allocates an independent memory block to each located target to save the target's subscription information, routing information, location information, and other information needed for business processes. We call such a block of memory a user context. When the authentication of a positioning request is passed, GMLC shall establish a context for each target in the request, fill in the necessary information, and start the relevant business process for each context. After the process ends, GMLC should delete the context in time to release system resources. [0003] A typical location request is for a single target. After GMLC executes the relevant process and...
