[0036] Such as figure 2 As shown, it is a flow chart of the steps of the method for triggering network switching in the first embodiment of the present invention, and this embodiment includes the following steps:

[0037] Step 101, when the radio bearer for the terminal to enter the voice service starts to be established, obtain the downlink reference signal received power RSRP of the terminal.

[0038] In this step, when the radio bearer for the terminal to enter the voice service starts to be established, the base station side obtains the downlink RSRP of the terminal. Specifically, if the downlink RSRP of the terminal is greater than the voice service interoperability threshold for network switching, network switching will not be triggered at this time, that is, the problem of call drop due to network switching will not occur. However, if the downlink RSRP of the terminal is less than the voice service interoperability threshold for network handover, network handover may ...

[0064] In this step, specifically, when the radio bearer for the terminal to enter the voice service starts to be established, the base station side acquires the downlink RSRP of the terminal. Specifically, if the downlink RSRP of the terminal is greater than the voice service interoperability threshold for network switching, network switching will not be triggered at this time, that is, the problem of call drop due to network switching will not occur. However, if the downlink RSRP of the terminal is less than the voice service interoperability threshold for network switching, networ...

Abstract

The invention provides a method and apparatus for triggering network switching. The method includes the following steps that: when a terminal enters a stage in which the establishment of the radio bearer of voice services is initiated, the downlink reference signal receiving power (RSRP) of the terminal is obtained; if the downlink reference signal receiving power (RSRP) is smaller than a voice service interoperation threshold value of the network switching, the preset parameters of the terminal in executing current voice services are detected; whether the current voice services are in a stage from call initiating to ringing is judged according to the preset parameters; if the current voice services are in the stage from call initiating to ringing, the network switching is not triggered; and if the current voice services are not in the stage from call initiating to ringing, the network switching is triggered. With the method and apparatus of the invention adopted, the problem of call drop caused by the failure of the switching of a network which is triggered to be switched at the stage from call initiating to ringing can be solved.

Description

technical field [0001] The present invention relates to the wireless field, in particular to a method and device for triggering network switching. Background technique [0002] In an LTE network, the data service interoperability threshold and the voice service interoperability threshold can be set independently. In order to enable users to enjoy high-speed data services while staying on the LTE network as much as possible, the data service interoperability threshold is usually set relatively low. For example, the threshold of data redirection is set as Reference Signal Receiving Power (RSRP, Reference Signal Receiving Power)=-124dBm. When the signal strength of LTE is lower than the threshold, the system transfers the user to 2G. For the voice service, in order to ensure the user's voice quality and call drop experience, the voice interoperability threshold is usually set higher, for example, RSRP=-116dBm. When the signal strength of LTE is lower than the threshold, the s...
