Embodiment 1

[0026] Embodiment 1 of the present invention provides a network selection method in the case of coexistence of multiple networks, which is applied to a user terminal UE based on a multi-mode, and the UE is used to store information related to the first network and the second network. The information at least includes network data transmission rate information and network load information; wherein the data transmission rate of the first network is greater than that of the second network, and the load of the second network is smaller than that of the first network, see figure 1 , the method includes the following steps:

[0027] S10. Determine the business type;

[0028] S11. For the real-time service, select the first network, and preferentially carry the real-time service through the first network;

[0029] S12. For the non-real-time service, select the second network, and preferentially carry the non-real-time service through the second network;

[0030] S13. When the commu...

Embodiment 2

[0046] Based on Embodiment 1, this embodiment of the present invention provides a multi-mode terminal device, see figure 2 In this embodiment of the present invention, the terminal device includes a network identification module 201, such as a SIM card, for storing information related to the first network and the second network, and the related information includes at least network data transmission rate information and network load information, and the The network identification module also compares the data transmission rate information and load information of the two networks, wherein the data transmission rate of the first network is greater than that of the second network, and the load of the second network is smaller than that of the first network; For specific descriptions, refer to the relevant part of the description in Embodiment 1, and details are not repeated here.

Embodiment 3

[0056] The embodiment of the present invention is based on the foregoing embodiments, and the solution is specifically described by taking the first network as a 3G network and the second network as a 2G network.

[0057] see image 3 , is a schematic diagram of the embodiment of the present invention, the left side of the figure is a terminal device (such as a mobile phone), the terminal includes a 3G module, a 2G module, a network identification module, such as a SIM card or a USIM card and other related modules. Among them, the 3G module is preferentially used to complete real-time services, comparing the loads of the 2G network and the 3G network, when the load of the 3G network is low, the 3G module is preferentially used to complete non-real-time services. When the 2G network load is low, the 2G module is preferentially used to complete non-real-time services. When the 2G or 3G module executes related services, it also needs to interact with some network elements. Thes...

Abstract

The embodiment of the invention discloses a network selection method based on multi-network convergence and a multi-mode terminal device. The multi-model terminal device stores and compares network data transmission rate information and network load information of a first network and second network; types of services to be launched or received by the terminal device are judged, wherein the services comprise the real-time services and the non-real-time services; as for the real-time services, networks with high data transmission rates are optimally selected by the multi-mode terminal, and if communication quality of the current optimally-selected networks can not meet requirements of the real-time services, the current optimally-selected network is switched to another network, and the real-time services are carried by the other network; as for the non-real-time services, networks with small loads are optimally selected by UE. By means of the method, the quality of the real-time services can be guaranteed, network loads can be balanced, and user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for a multi-mode terminal to select a network in an environment where multiple networks coexist and a multi-mode terminal device. Background technique [0002] At present, wireless communication technology is developing rapidly, from 2G, 3G, to LTE (Long Term Evolution, long-term evolution), WiMax (Worldwide Interoperability For Microwave Access, global microwave interconnection access), etc., wireless communication systems are in data transmission speed, system Performance aspects such as capacity and time delay have been greatly improved. Many countries in the world support multiple wireless communication networks of different standards. Therefore, multiple different heterogeneous networks jointly cover a certain area. These networks are characterized by certain differences in coverage, data rates, and applicable service types. For example, some...
