Handover threshold adjustment method and device for session network

Abstract

The invention discloses a switching threshold adjustment method of a session network, which presets a first switching threshold and a second switching threshold corresponding to each geographic location; obtains data transmission parameters of a network where a terminal is currently located, and adopts a preset offset The value calculation rule processes the data transmission parameters to obtain a first modified offset value; when the first switching threshold is greater than the second switching threshold corresponding to the current geographic location of the terminal, the first modified offset value is used to correct the The first switching threshold is used to obtain the current switching threshold; otherwise, the first switching threshold is determined as the current switching threshold. The invention also discloses a device and a storage medium for adjusting the switching threshold of the session network.

Description

technical field [0001] The invention relates to the technical field of network switching in mobile communication, in particular to a method and device for adjusting a switching threshold of a session network. Background technique [0002] Wireless call (WFC, WiFi calling) is an important emerging technology in the fourth generation + (4G+, 4th Generation+) communication network era. WFC is an Internet Protocol Multimedia Subsystem (IMS, IPMultimedia Subsystem) video or voice based on WiFi network In the call service, terminal users can make IMS video or voice calls in the WiFi environment; during the voice over long-term evolution (VoLTE, Voice over Long Term Evolution) call, if entering an area where the mobile communication network coverage environment is not ideal, the mobile terminal It can switch the IMS video or voice call from the LTE network to the WiFi network, and turn it into a WFC call; during the switching process between WFC and VoLTE, the mobile terminal is co...

[0002] Wireless call (WFC, WiFi calling) is an important emerging technology in the fourth generation + (4G+, 4th Generation+) communication network era. WFC is an Internet Protocol Multimedia Subsystem (IMS, IPMultimedia Subsystem) video or voice based on WiFi network In the call service, terminal users can make IMS video or voice calls in the WiFi environment; during the voice over long-term evolution (VoLTE, Voice over Long Term Evolution) call, if entering an area where the mobile communication network coverage environment is not ideal, the mobile terminal It can switch the IMS video or voice call from the LTE network to the WiFi network, and turn it into a WFC call; during the switching process between WFC and VoLTE, the mobile terminal is connected between the wireless local area network (WLAN, Wireless Local Area Networks) and the radio access network (RAN, Radio Access Network), it is necessary to ensure that the quality of the call is not reduced, the call is not interrupted, and the user has no perception; however, existing mobile terminals have the problem that the network switching threshold cannot be flexibly and adaptively adjusted during network switching; for example : The signal of the Long Term Evolution (LTE, Long Term Evolution) network is good, the signal strength is not lower than the handover threshold, and the throughput rate of LTE data packets has declined, causing the voice or video call quality to be low. If the mobile terminal The priority mode configuration of the mid-call function is cellular (cellular) mode, even if the WiFi network signal is good, the call will not be switched to the WiFi network immediately; on the contrary, if the WiFi network signal is good, the signal strength is not lower than the switching threshold, but the data The packet throughput rate has dropped, resulting in poor voice or video call quality. If the priority mode configuration of the call function in the terminal is WiFi network mode, even if the LTE network signal is good, the call will not be switched to the LTE network immediately.
