Embodiment 1

[0068] see figure 1 , which is a method flowchart of a communication mode switching method of the present invention, the method includes the following steps:

[0069] S101: receiving a transmission request;

[0070] The so-called transmission request can be considered as a request triggered by the user by pressing the call button of the mobile station or entering the menu to edit the short message, that is to say, the types of the transmission request include at least voice type and text type or Signaling type transmission request.

[0071] S102: Detect whether the radio frequency signal strength of the downlink channel meets the first threshold;

[0072] That is to say, as long as the relay station is in the working state, no matter whether the relay station is forwarding the signals of other mobile stations, the downlink channel of the mobile station under the signal coverage of the relay station can at least receive a certain strength of the carrier signal, so this It is...

Embodiment 2

[0092] On the basis of Embodiment 1, this embodiment will mainly describe how to switch from offline mode to transfer mode, please refer to Figure 4 , which is another method flowchart of a communication mode switching method of the present invention, after completing the transmission request in the off-network mode, it also includes:

[0093] Before introducing the technical solution, first introduce how to enter the holding state after completing the transmission request in the off-network mode and what is the holding state.

[0094] Generally speaking, the system will set a certain hold time, so that the mobile station that has just finished the call can quickly establish a call again within the hold time, and the mobile station that receives the text or signaling can quickly respond to the call within the hold time. The mobile station of the signaling responds. The holding time is pre-set by the system. There are different holding times for different transmission signal t...

Embodiment 3

[0115] Corresponding to the foregoing communication mode switching method, an embodiment of the present invention further provides a communication mode switching device. see Figure 5 , which is a device structure diagram of a communication mode switching device according to the present invention, which includes a receiving and transmitting request unit 501 , a first threshold detection unit 502 , a hold transfer mode unit 503 and a switching offline mode unit 504 .

[0116] The receiving transmission request unit 501 is configured to receive a transmission request;

[0117] The first threshold detection unit 502 is configured to detect whether the radio frequency signal strength of the downlink channel meets the first threshold;

[0118] Keeping the relay mode unit 503, configured to determine that the relay station is in the working state when the detection result of the first threshold detection unit 502 is greater than or equal to the first threshold, and maintain the rel...

Abstract

The embodiment of the invention discloses a communication mode switching method and device. The method comprises the following steps of: receiving a sending request; detecting whether the radio frequency signal strength of a downlink channel meets a first threshold; when the radio frequency signal strength is greater than the first threshold, judging that a relay station is in a working state, and keeping a relaying mode to finish the sending request; when the radio frequency signal strength is less than the first threshold, judging that the relay station is in an abnormal state, and switching to an offline mode to finish the sending request, wherein the offline mode specifically is to perform sending after regulating the sending frequency to be the receiving frequency of the downlink channel. Obviously, whether the relay station is in the abnormal state is judged by detecting whether the signal strength of the downlink channel meets the preset threshold, sequentially, the working mode is switched between the relaying mode and the offline mode in a targeted manner, thus, when the relay station is in the abnormal state, the receiving frequency of the downlink channel is used as the sending frequency for sending signals, so that other mobile stations are guaranteed to be capable of receiving the sent signals, and the rate of call lost is lowered.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication mode switching method and device. Background technique [0002] When the mobile station and the repeater work in the fast activation repeater mode, the repeater is in an abnormal state when there is no signal to be relayed. At the same time, generally speaking, any signal transmitted by a mobile station within the signal range of the repeater may be relayed. The station wakes up to the working state, synchronizes the relay station to the timing of the mobile station, and then relays the signal of the mobile station. In this case, the process of activating the base station is not required, which can greatly reduce the call access time. [0003] However, in the prior art, the mobile station cannot know the current state of the relay station in advance before obtaining the transmission request for transmission. If the relay station is currently in an abnormal state,...
