Embodiment Construction

[0024] The inventor noticed that the 3GPP standard not only defines the configurable working modes of the terminal and the network side, but also defines two types of terminal features in order to distinguish the terminal from the aspects of the main supported services, namely "mainly voice services" (Voice Centric)” and “Data Centric”.

[0025] Combining the above two types of terminal features, the inventor proposed a scheme for determining the network interoperability mode. The basic idea of ​​the scheme is: according to the feature type set by the terminal, combined with the working mode of the network side and terminal configuration to determine the network interoperability model.

[0026] Specifically: when the feature type of the terminal is mainly voice services, if it is determined according to the working modes of the network side and the terminal that both the network side and the terminal can support the CS Fallback interactive mode, it is set to preferentially res...

Abstract

The invention discloses a method for determining a network interoperable mode and terminal equipment which are used for solving the problems that the time for call ringing and waiting is long, and the probability for call drop and the electric power consumption are increased because the terminal is subjected to frequently reselection among different networks in the prior art. The method is applied to the terminal which supports the LTE (Long Term Evolution) access technology, and supports at least one of 2G (2nd Generation) access technology and 3G (3rd Generation) access technology. The method comprises the following steps of: when the terminal accesses a network, determining whether a network side supports a CS (Circuit Switch) fallback mode or not; when the network side is determined to support the CS fallback mode, and the characteristic type of the settings of the network side gives priority to voice, determining to prefer to dwelling at a 2G network or a 3G network; when data service is carried out under the condition of dwelling at the 2G network or the 3G network, determining whether the reselection to an LTE network is needed or not; and when the terminal determines to reselect to the LTE network, reselecting to the LTE network and executing the data service, and returning to the 2G network or the 3G network after the data service is finished.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for determining a network interoperability mode and a terminal device. Background technique [0002] Under the current situation that 2G network has been widely popularized and 2G technology has become a mature and reliable communication method, 3G network has also been gradually promoted. At the same time, with the introduction and development of Long Term Evolution (LTE, Long Term Evolution) network, the future will face The long-term coexistence of various networks such as 2G, 3G, LTE, and wireless local area network (WLAN, Wireless Local Area Network). In order to solve the problem of continuity of voice services and data services between multiple networks, the existing technology provides a variety of standardized interoperability solutions for selection, among which VoLTE / IMS and CS Fallback modes are mainly included in the 3GPP international standards...
