Embodiment Construction

[0043] The basic idea of ​​the present invention is: set a backup carrier frequency in the internal communication module, and when it is detected that the interference of the current carrier frequency of the internal communication exceeds a set threshold, use the backup carrier frequency to establish a communication channel with the terminal, and transmit the communication service with the terminal by using the established spare carrier frequency channel.

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. figure 2 It is a schematic flow chart of the internal communication switching method in Embodiment 1 of the present invention; figure 2 As shown, the internal communication switching method of this embodiment includes the following steps:

[0045] Step 201: When it is detected that the carrier frequency of the current internal communication is subject to interference exceeding the...

Abstract

The invention discloses a switching method of an internal communication. The method comprises the following steps: when detecting that the interference received by a carrier frequency of the current internal communication exceeds a set threshold value, sending a notification message for selecting a standby carrier frequency to perform the internal communication to the terminal in the internal communication; determining that the terminal is switched to the standby carrier frequency, establishing a channel for communication by using the standby carrier frequency and the terminal, and transmitting the communication service between the standby carrier frequency and the terminal by using the established channel of the standby carrier frequency. The invention further discloses a switching device of the internal communication. Through the adoption of the technical scheme disclosed by the invention, the problem that the internal communication in a hybrid network is easy to be interfered by a wireless network communication signal can be solved, the call interrupt phenomenon caused by the condition that the internal communication is interfered is overcome, and the communication quality of the internal communication is prompted.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a switching method and device for internal communication. Background technique [0002] At present, there are mainly two types of mobile communication networks: wireless networks with centralized control and peer-to-peer networks with distributed control. In a wireless network, even if two user equipments (UE, User Equipment) are very close to each other, a central controller such as a base station must be used for communication control, including transmission power control and resource allocation. Such a centralized control system is convenient for resource management and interference control, but the utilization efficiency of resources is not very high. Therefore, in order to improve spectrum usage efficiency and obtain higher system throughput, a device-to-device direct communication (D2D, Device-to-Device communication) is proposed in the LTE-Advanced (Long Term...
