Embodiment 1
[0136] If the network switching time does not exceed the switching timer (Switch Timer), that is, the switching timer does not expire during the period from when the terminal leaves network A to returning to network A, the network reserves the allocated resources. When the terminal returns to network A, it uses the allocated resources to restore the connection.
[0137] see Figure 4 ,Specific steps are as follows:
[0138] Step 1: SIM card 1 of the terminal executes low-priority services on network A, and SIM1 of the terminal is in a connected state.
[0139] Optionally, the network sends the pre-configuration of the connection suspension mode to the terminal.
[0140] Step 2: The SIM card 2 of the terminal initiates a high-priority service on network B.
[0141] Services on network B have a higher priority than services on original network A. For example, SIM card 1 of the terminal performs data services on network A, and SIM card 2 of the terminal initiates or receives v...
Embodiment 2
[0152] If the network switching time exceeds the duration of the switching timer, that is, the switching timer has expired during the period from when the terminal leaves network A to returning to network A, the network may not reserve the allocated resources. When the terminal returns to network A, it initiates an RRC reestablishment process to restore the connection with network A.
[0153] see Figure 5 ,Specific steps are as follows:
[0154] Step 1: The SIM card 1 of the terminal performs low-priority services on network A, and the SIM card 1 of the terminal is in a connected state.
[0155] Optionally, the network sends the pre-configuration of the connection suspension mode to the SIM card 1 of the terminal.
[0156] Step 2: The SIM card 2 of the terminal initiates a high-priority service on network B.
[0157] Services on network B have higher priority than services on network A. For example, SIM card 1 of the terminal performs data services on network A, and SIM ca...

Abstract
The embodiment of the invention provides a network conversion method and equipment, and the method comprises the steps: starting a conversion timer under the condition that a terminal leaves a first network; and recovering the connection between the terminal and the first network through a corresponding network resource according to the state of the conversion timer, wherein the state of the conversion timer comprises that the conversion timer is overtime or the conversion timer is not overtime, so that the terminal can quickly recover the connection with the first network, and the terminal is supported to quickly recover the previously suspended service.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a network conversion method and device. Background technique [0002] In the existing mobile communication system, for a multi-card terminal that can only support one network connection, when the Subscriber Identification Module (Subscriber Identification Module, SIM) card 1 of the multi-card terminal needs to temporarily leave a network A, it will hang up. Start the service of SIM card 1 on network A, and trigger network switching. During the service suspension period on network A, network A cannot receive the data of the multi-card terminal, which may trigger a series of error processing, including: wireless link failure, release of allocated resources, etc. [0003] When the multi-card terminal returns to network A to continue the service of SIM card 1, the multi-card terminal will try to restore the service on SIM card 1 through the dedic...
