Method for realizing concurrency of CS (circuit switching) and PS (packet switching) and device for realizing concurrency of CS and PS

Abstract

The invention relates to a method for realizing concurrency of CS (circuit switching) and PS (packet switching) and a device for realizing concurrency of CS and PS. The method includes the steps of starting a PS business, judging the type of the PS business, activating a CS paging channel object when the PS business is a data transmission business, and regulating the priority of the CS paging channel object and a paging channel object of the PS business, so that a CS business and the PS business are concurrently processed. Without increasing hardware cost, the CS business is intervened into the PS business by making full use of the retransmission mechanism of the PS business and the time division characteristic of a GSM (global system for mobile communications), CS paging is monitored under the condition of ensuring a user not to experience interruption so that CS paging is not lost while the PS business is performed, the PS business is automatically restored after monitoring is completed, so that the PS business continues to be transmitted, data block loss caused by monitoring of CS paging in the past can be made up by utilizing the mechanism, and influence on the PS business is minimized.

Description

technical field [0001] The present invention relates to the field of mobile communications, in particular to a CS (Circuit Bearer Domain) and PS ( Data domain) concurrency implementation method and device. Background technique [0002] With the rapid development of mobile communication technology, using mobile terminals to perform high-speed packet data domain (PS) services (hereinafter referred to as PS services), such as surfing the Internet, sending and receiving emails anytime and anywhere, has become the most basic requirement of users, but No matter how powerful the PS service of the mobile terminal is, the most basic circuit bearer domain (CS) service (hereinafter referred to as the CS service), such as the most basic call, is still the basic demand of most users, especially in mountainous areas where the network is not yet developed. In remote areas, the network is not enough to support the Internet service of the mobile terminal, and its basic call service has beco...

AI Technical Summary

Problems solved by technology

[0004] At present, mobile phones on the market are divided into three categories. The first category of mobile phones supports CS and PS services at the same time, that is, voice calls and data transmission can be carried out at the same time, which requires two sets of sending and receiving resources to support, resulting in high costs; the second category The mobile phone and the third type of mobile phone can switch between CS and PS services, and only need a set of sending and receiving resources to support it, and the cost is low. However, the third type of mobile phone needs to switch between the two services manually, so the user Inconvenience; currently most of the mobile phones on the market are second-class mobile phones. Although the second-class mobile phones can automatically switch between the two services, due to the limitation of hardware resources, most of the second-class mobile phones are in the PS business. , CS paging cannot be monitored, resulting in paging loss, which brings troubles to many users, such as losing an important call while sending and receiving emails, etc.
