In a possible implementation manner, time-frequency resources that can be used by intercom devices with different vocoders can be preconfigured, and intercom devices with the same vocoder can be configured to use the same time-frequency resources, so as to establish a corresponding relationship between the preset time-frequency resources and the vocoders, and after the repeater determines to acquire the time-frequency resources of the voice signals, the corresponding encoder can be obtained according to the corresponding relationship. The correspondence may be stored in the repeater in the form of a table, or may be stored in other forms, which is not limited in this disclosure.
In a possible implementation manner, the time-frequency resources may include time-domain resources and frequency-domain resources, and for intercom devices of different vocoders, different time-domain resources having the same frequency-domain resources may be set and used, different frequency-domain resources having the same time-domain resources may be set and used, different time-domain resources having different frequency-domain resources may be set and used, different frequency-domain resources having different time-domain resources may be set and used, and the like, which is not limited herein.

In this manner, the repeater may transmit the first voice signal to other intercom devices having the first vocoder.
The above method will now be illustrated, it being understood that the following examples are described to better illustrate the present disclosure and should not be taken as limiting the same.
In an example, two sets of the corresponding relations (a first corresponding relation and a second corresponding relation) may be configured, the first corresponding relation may be that the vocoder AMBE corresponds to a 0 time slot corresponding to the uplink frequency point 403.125 and a 0 time slot corresponding to the downlink frequency point 435.125, and the second corresponding relation may be that the vocoder Vitas corresponds to a1 time slot corresponding to the uplink frequency point 403.125 and a1 time slot corresponding to the downlink frequency point 435.125 (the frequency domain resources are the same, and the time domain resources are different). In this example, the vocoder AMBE may be used as the first vocoder, and accordingly, the 0 timeslot corresponding to the uplink frequency point 403.125 and the 0 timeslot corresponding to the downlink frequency point 435.125 may be used as the first time-frequency resource; the vocoder Vitas can be used as a second vocoder, and the corresponding 1 time slot of the uplink frequency point 403.125 and the 1 time slot of the downlink frequency point 435.125 can be used as the second time frequency resource.
All talkback equipment using the vocoder AMBE can be set to use the 0 time slot corresponding to the uplink frequency point 403.125 and the 0 time slot corresponding to the downlink frequency point 435.125 as the channel setting parameters of the talkback equipment;
all talkback devices using the Viteas of the vocoder can use the 1 time slot corresponding to the uplink frequency point 403.125 and the 1 time slot corresponding to the downlink frequency point 435.125 as channel setting parameters of the talkback devices;
when the repeater receives the first voice signal in the 0 time slot of the uplink frequency point 403.125, the data is decoded into a decoded voice signal by the vocoder AMBE, and then the decoded voice signal is encoded into a second voice signal by the Viteas vocoder and forwarded. I.e., voice data received in the 0 slot of uplink frequency point 403.125, the second voice signal is forwarded in the 1 slot of downlink frequency point 435.125, while the repeater also transmits the first voice signal in the 0 slot of downlink frequency point 435.125.
When the repeater receives uplink data in 1 time slot of the uplink frequency point 403.125, the data is decoded into a decoded voice signal by the vocoder AMBE, and then the decoded voice signal is encoded into a second voice signal by the Viteas vocoder and forwarded. I.e., voice data received on 1 slot of 403.125, the second voice signal is forwarded on 1 slot of 435.125 while the repeater also transmits the first voice signal on 0 slot of 435.125 of the downlink frequency point.
In an example, two sets of the corresponding relations (a third corresponding relation and a fourth corresponding relation) may be configured, the third corresponding relation may be that the vocoder AMBE corresponds to the 0 time slot corresponding to the uplink frequency point 403.125 and the 0 time slot corresponding to the downlink frequency point 435.125, and the second corresponding relation may be that the vocoder Vitas corresponds to the 0 time slot corresponding to the uplink frequency point 460.1 and the 0 time slot corresponding to the downlink frequency point 469.175 (the time domain resources are the same, and the frequency domain resources are different). In this example, the vocoder AMBE may be used as the first vocoder, and accordingly, the 0 timeslot corresponding to the uplink frequency point 403.125 and the 0 timeslot corresponding to the downlink frequency point 435.125 may be used as the first time-frequency resource; the vocoder Vitas can be used as a second vocoder, and the corresponding 0 time slot corresponding to the uplink frequency point 460.1 and the 0 time slot corresponding to the downlink frequency point 469.175 can be used as the second time frequency resource.
All talkback equipment using a vocoder AMBE can be set to use the 0 time slot of the uplink frequency point 403.125 and the 0 time slot of the downlink frequency point 435.125 as channel setting parameters of the talkback equipment;
all talkback devices using the Vitas of the vocoder can use the 0 time slot of the Vitas of the vocoder and the uplink frequency point 460.1 and the 0 time slot of the downlink frequency point 469.175 as channel setting parameters of the talkback devices;
when the repeater receives the first voice signal in the 0 time slot of the uplink frequency point 403.125, the first voice signal is decoded by the vocoder AMBE to generate a decoded voice signal, and then the second voice signal is forwarded after the decoded voice signal is encoded by the Viteas vocoder to generate the second voice signal. I.e., the first voice signal received on time slot 0 of 403.125, the second voice signal is forwarded on time slot 0 of 469.175, while the repeater also transmits the first voice signal on time slot 0 of 435.125 of the downlink frequency point. (ii) a Or
When the repeater is used for decoding the first voice signal in the 0 time slot of the uplink frequency point 460.1, the vocoder Vitas is used for decoding the first voice signal to generate a decoded voice signal, and then the AMBE vocoder is used for coding the decoded voice signal to generate a second voice signal, and then the second voice signal is forwarded. I.e., voice data received on 0 time slot of 460.1, the second voice signal is forwarded on 0 time slot of 435.125 while the repeater also transmits the first voice signal on 0 time slot of 469.175.
It is to be understood that the above description is intended to be illustrative, and not restrictive, of the present disclosure. In other embodiments, other corresponding relationships may be configured, or the time-frequency resource corresponding to the above decoder may be reset, which is not limited in this disclosure.
