Embodiment Construction

[0025] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] Such as figure 2 As shown, it is a schematic flow chart of an embodiment of the method for implementing voice call priority when sending short messages through the service channel in the present invention. In this embodiment, the method for implementing voice call priority includes:

[0027] Step 101, when the MS detects a voice call origination request, it judges the current state of the MS;

[0028] Step 102, when it is determined that the MS is in the idle state or the paging response sub-state, the MS sends the voice call initiation request to the BSS;

[0029] Step 103, the BSS sends a voice call initiation request confirmation to the MS, and sends a voice call initiation request to the MSC;

[0030] Step 104, the MSC judges whether to send a short message paging request, if yes, execute step 105, other...

Abstract

The invention relates to a voice call preferential realization method during short message sending through a service channel. The method comprises the following steps: when a voice initial call request is detected, a mobile station judges the current state; in the case of an idle state or a paging response sub-state, the mobile station sends the voice initial call request to a BSS (base station subsystem); the BSS returns a voice initial call request acknowledgement and sends a voice initial call request to an MSC (mobile switching center); the MSC judges whether to send a short message paging request; if so, the MSC suspends the short message processing process, caches the short message to be sent, and then performs standard voice initial call flow processing, and sends the cached short message in an established voice service channel; and if not, the MSC performs standard voice initial call flow processing. The method provided by the invention realizes voice preference function through processing ways on different equipment based on the judgment on different message sending states and stages when the voice request is generated, ensures preferential continuing of voice service with higher real-time requirement, and processes the two kinds of services (short message and voice) according to priority.

Description

technical field [0001] The invention relates to the technical field of code division multiple access, in particular to a method for implementing voice call priority when sending short messages through a business channel. Background technique [0002] In a Code Division Multiple Access (CDMA for short) system, a Mobile Switching Center (MSC for short) can set whether to send a short message to a user through a control channel or a service channel according to the length of the short message. In order to avoid the congestion of the control channel caused by sudden SMS services and improve the success rate of SMS messages, telecom operators usually only set ultra-short SMS messages to be sent through the control channel, and other Both are set to be delivered through the service channel. [0003] For the signaling process of the existing MSC sending short messages through the service channel, please refer to figure 1 After the MSC receives the message from the short message c...
