Embodiment 1

[0080] Embodiment 1 of the present invention provides a method for switching access modes of a multi-mode dual-card terminal, such as figure 1 As shown, it is a schematic flowchart of the access mode switching method of the multi-mode dual-card terminal described in Embodiment 1 of the present invention, and the method may include the following steps:

[0081] Step 101: If it is determined that the main card of the multi-mode dual-card terminal cannot be used normally, and it is determined that the secondary card of the multi-mode dual-card terminal is available and the secondary card supports all channels except the secondary channel of the multi-mode dual-card terminal At least one access mode other than the supported access mode indicates that the main path of the multi-mode dual-card terminal is related to the secondary card according to the secondary card or the multi-mode dual-card terminal pre-stored The PLMN frequency point list of the operator's network is used to sea...

Embodiment 2

[0139] Based on the same inventive concept, Embodiment 2 of the present invention provides an access mode switching device for a multi-mode dual-card terminal, such as Figure 5 As shown, it is a schematic structural diagram of the access mode switching device of the multi-mode dual-card terminal described in Embodiment 2 of the present invention, and the access mode switching device may specifically include:

[0140] The determination module 51 can be used to determine whether the multi-mode dual-card terminal meets the following conditions: the main card of the multi-mode dual-card terminal cannot be used normally, and the secondary card of the multi-mode dual-card terminal is available and the secondary card Support at least one access mode other than the access mode supported by the secondary channel of the multi-mode dual-card terminal; specifically, if it is determined that the main card of the multi-mode dual-card terminal has When the signal quality is lower than the p...

Abstract

The invention discloses an access mode switching method of a multimode double-card terminal and a related device. The access mode switching method comprises the steps of if a fact that a main card cannot be used normally, a secondary card is in an available state and the secondary card support at least one other access mode except for an access mode supported by a secondary path is determined, indicating a main path to carry out network search of a set access mode according to a pre-stored PLMN (Public Land Mobile Network) frequency point list of an operator network related to the secondary card; and when determining that an available set access mode cell is searched, indicating a main path to access to a network corresponding to the searched set access mode cell, wherein the set access mode indicates an access mode which is supported by the secondary card rather than a secondary path, that is to say, a user can use one or multiple wireless access technologies supported by the secondary card to carry out corresponding service transmission through the main path and is no longer limited by the access mode supported by the secondary path. Therefore, the practical access capability of the secondary card is extended, and the flexibility of the terminal use mode is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for switching access modes of a multi-mode dual-card terminal and related equipment. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is the follow-up evolution technology of 3G (3rd Generation, third-generation mobile communication). With its unique technical advantages such as high data rate, low delay, optimized network architecture, and larger carrier bandwidth, it has become a International mainstream new generation broadband mobile communication standard. In the early stage of LTE development, the LTE network could not achieve full coverage. At the same time, because the LTE network is based on the all-IP (Internet Protocol, network protocol) architecture, it can only provide VoIP (Voice over Internet Protocol, that is, voice transmission based on IP protocol) services based on the packet domain. Therefore, LTE terminals ge...
