Problems solved by technology

[0013] The above-mentioned reselection / handover method from the 2G network to the 3G network in the prior art mainly has the following disadvantages: due to the poor coverage quality of the current 3G network, reselection or handover between different systems often occurs, and the call or data service remains Switching between different systems during the process may increase the call drop rate or drop rate, and will increase the power consumption of the terminal and reduce the standby time of the terminal
[0016] It can be seen that there are some deficiencies in the above-mentioned reselection / handover methods from the 2G network to the 3G network in the prior art

Embodiment 1

[0073] Please refer to figure 2 The method for selecting a service bearer network described in this embodiment includes:

[0074] Step 21, after the terminal is turned on, if it detects signals of both the 2G network and the 3G network, it initially resides in the 2G network.

[0075] In this embodiment, when the 2G network and the 3G network coexist, the terminal will preferentially reside in the 2G network after it is powered on. Choose to return to the 2G network. In this way, before initiating any service, the terminal resides in the 2G network.

[0076] Step 22, when the terminal residing in the 2G network detects that the user initiates a service, it judges the type of the service: if it is a CS service, proceed to step 23; if it is a PS service, proceed to step 24.

[0077] Step 23, the terminal executes the CS service in the 2G network, and ends this process after the execution is completed.

[0078] Step 24, the terminal judges whether the signal quality measurem...

Embodiment 2

[0095] Such as Figure 4 As shown, the method for selecting a service bearer network described in this embodiment specifically includes:

[0096] Step 31 , after the terminal is turned on, if it detects signals of both the 2G network and the 3G network, it initially resides in the 2G network.

[0097] Step 32, when the terminal residing in the 2G network detects that the user initiates a service, it judges the type of the service: if it is a CS service, proceed to step 33; if it is a PS service, proceed to step 34.

[0098] Step 33, the terminal executes the CS service in the 2G network, and ends this process after the execution is completed.

[0099] Step 34, the terminal judges whether the signal quality measurement value of the 3G network is greater than the sum of the reselection threshold offset preset on the terminal side and the absolute threshold value of the reselection judgment between the 2G network and the 3G network issued by the network side , the reselection t...

Embodiment 3

[0119] Considering that the data volume of the PS service initiated by the user can be large or small, and the conversion range is large. For example, when the user just sends a multimedia message or browses a simple web page, the data flow of the PS service is usually around tens of KB; When the PS service initiated by the user is to watch a long-time video stream, the service volume will be very large at this time, reaching tens or hundreds of MB. The 3G network is more suitable for carrying PS services with a large amount of data. Therefore, in this embodiment, after judging that the signal quality measurement value of the 3G network is not greater than the absolute threshold value of the inter-system reselection decision, it can further be based on the determined The execution time of the PS service in the 2G network is used to determine whether to reselect to the 3G network.

[0120] Such as Image 6 As shown, the method for selecting a service bearer network described i...

Abstract

The invention provides a method and a terminal for selecting a service bearing network. In the method, a service bearing network is selected according to service type and 3G (3rd generation telecommunication) network signal quality, and a threshold of cell reselection among different systems is improved, so that probability that reselection among different systems frequently occurs in a terminal is reduced, success rate of being called of the terminal is improved, power consumption of the terminal is saved, and standby time of the terminal is prolonged; under a condition of ensuing excellent service use experience of users, the advantages of the prior 2G (2nd Generation) and 3G networks are fully used, rational service division is implemented, and the prior network resource is rationally used.

Description

technical field [0001] The invention relates to a mobile communication network, in particular to a method for selecting a service bearing network and a terminal. Background technique [0002] The third-generation mobile communication (3G) networks, such as TD-SCDMA, WCDMA and CDMA2000 networks, have been put into commercial use. The 3G network provides users with a variety of services, such as videophone, video message, high-speed Internet access, video surveillance, mobile TV and many other services. Although the 3G network is becoming more and more mature and the commercial level is increasing rapidly, there is still a certain gap between the service quality expected by users. Through a large-scale network test, it is found that due to the limitations of the current 3G network coverage, capacity level, terminal equipment performance and type, etc., the service quality of the 3G network is still significantly lower than that of the second generation mobile communication (2...
