example 1

[0083] hypothetical network scenario Figure 5 As shown, the base station may be the RNC and / or NodeB of the UMTS system, or the eNB of the LTE system, and the access point is the AP of the WLAN.

[0084] Under the common coverage of the base station and WLAN AP, the terminal receives the system information sent by the base station, which contains information related to WLAN. For example, the related information may include the identification of WLAN APs available nearby. At this time, the UE can perform Handover-related evaluation, found that its own ability can support access to two networks at the same time, but at this time the network sent WLAN-related information, UE evaluated the target network and found that the target network does not meet the conditions for all services to be handed over, so the UE will not All services are switched to WLAN, but some or all services are reserved on the 3GPP network.

example 2

[0086] When the terminal is under the common coverage of the base station and the WLAN AP, the base station can notify the UE of the strategy selected by the network and related auxiliary information through broadcast or dedicated signaling. In the case of the base station broadcasting, the terminal receives the system information sent by the base station, wherein the network notifies the UE that all services are not allowed to be switched to the WLAN. At this time, regardless of whether the UE is capable of supporting access to multiple networks, the UE judges that all services cannot be switched. Therefore, the UE will retain some or all services on the 3GPP network.

[0087] For the case where the base station uses dedicated information, after the UE accesses the network, it can report to the network its ability to support only one access technology. After the network receives this information, it will not send handover related policies and auxiliary information to the UE. ...

example 3

[0089]The terminal is under the common coverage of the base station and WLAN AP. After the UE accesses the network, it reports its ability to support multiple access technologies to the network. After the network receives this information, it will not send all service switching commands to the UE. Only the UE will be notified to switch some services. Therefore, if the UE evaluates that the target network does not meet the conditions for switching all services, the UE will not switch all services to WLAN, but keep some or all services on the 3GPP network. When the UE is handed over in the 3GPP network, the source eNB transmits the capability information reported by the UE to the target eNB.

[0090] According to an embodiment of the present invention, a device for controlling service switching is also provided, and the device can be implemented on the UE side.

[0091] Such as Image 6 As shown, the device includes:

[0092] A judging module 61, configured to judge whether th...

Abstract

The invention discloses a service switching control method and a service switching control device. The method comprises the following steps: UE judges whether or not service switching is needed; and when the UE judges that service switching is needed, the UE prohibits all services from being switched to a target network if the UE does not support simultaneous access to multiple networks and / or the target network of switching does not satisfy the conditions for switching all the services of the UE. When the UE needs service switching, the capability of the UE and the target network are evaluated, so that switching of all the services of the UE can be controlled reasonably, the situation in which the UE directly switches all the services to the target network can be avoided, service data transmission interruption and other problems caused thereby are overcome, normal operation after service switching is ensured, and the user experience is improved. For example, the scheme of the invention enables a terminal supporting single access network capability to effectively maintain connection under an original network (such as a 3GPP network).

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a service switching control method and device. Background technique [0002] With the growth of user demand and the development of communication technology, more and more wireless communication technologies and related networks have emerged, for example, 2G / 3G / 4G mobile communication technologies and networks that can provide wide coverage, and wifi that can provide hotspot coverage Technology and Wireless Local Area Network (WLAN for short). Therefore, there are also scenarios where a large number of different communication networks coexist, such as scenarios where 2G / 3G / 4G networks and WLANs coexist. [0003] (1) In the scenario where Universal Mobile Telecommunications System (UMTS) / Long Term Evolution (LTE) and WLAN network coexist [0004] The Evolved Packet System (EPS for short) is a system that supports multiple access technologies and mobility between mul...
