Embodiment Construction

[0025] As mentioned above, the IP service of the user terminal can be switched between various 3GPP access networks (such as switching between a 3G network and a 4G network), and can also be switched between a 3GPP access network and a WLAN. However, when two types of switching can be performed at the same time, conflicts may occur and continuous switching occurs. For example, when the IP service of the user terminal meets the requirements of switching from 4G network to 3G network and from 4G network to WLAN at the same time, it may occur that the IP After the service is switched to the 3G network, it is judged that the IP service meets the conditions for switching from the 3G network to the WLAN. At this time, another switch is performed to switch the IP service to the WLAN. The situation of continuous switching will lead to low IP service processing efficiency, and also cause waste of terminal resources, so the switching mechanism needs to be improved.

Abstract

The invention discloses a network switching method and a network switching device for a user terminal. The network switching method comprises the steps of judging network environment information of the user terminal, when the network environment information simultaneously meets first condition information and second condition information, determining a first target network according to the first condition information or the second condition information, judging whether the network environment information related to the first target network still meets a switching strategy, and switching an IP service according to a judgment result. According to the method and the device provided by the invention, two switching processes are coordinated, continuous switching of the IP service is avoided, and thus processing efficiency of the IP service is enhanced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network switching method and device for a user terminal. Background technique [0002] The UMTS Terrestrial Radio Access Network (UTRAN) of the Universal Mobile Telecommunications System (UMTS) is an access mode of the third-generation mobile communication technology UMTS, and has a wide range of applications. [0003] In the Long Term Evolution (LTE, commonly known as 4G network), because of the evolution relationship, the access network part is usually called the Evolved UMTS Terrestrial Radio Access Network (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN) , that is, the mobile communication wireless network in LTE. [0004] Both UTRAN and LTE belong to the 3GPP access network. Wireless Local Area Networks (WLAN) is an IP network that can transmit data conveniently and efficiently. IP services of user terminals are IP-based services, including data services, IMS v...
