The invention discloses a network selection method for user equipment. The method comprises that: the user equipment establishes connection with a network side, receives network selection information formulated by the network side and performs network selection according to the network selection information, or receives the network selection information and a forcible network selection indication, and selects a network specified by the forcible network selection indication for accessing according to the network selection information, wherein the network selection information is information about all or a part of networks available for the user equipment at a current position. The invention also discloses the user equipment and a network selection function device. By the network selection method provided by the invention, the network can control the access network selection range of the UE.
Description
technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for user equipment to select a network. Background technique [0002] With the increasing demand for wireless communication services, more and more wireless communication technologies have entered or are entering the practical stage, for example, the widely used GSM / GPRS (Global System for Mobile communications / General Packet Radio System) system, UMTS (Universal Mobile Telecommunications System) system, WLAN (Wireless Local Area Network) system, WiMAX (Worldwide Interoperability for Microwave Access) system that is entering the practical stage, etc. These wireless access technologies have different capabilities and characteristics. For example, the GSM system can provide a wide range of mobility and good voice service quality, but the data service rate is very low; the UMTS system can provide a wide range of mobility and medium speed. Data service...
