According to the frame number of the current period, taking the frame number type of the current period with the odd frame number as a first type; and taking the frame number type of the current period with the even frame number as a second type.
Therefore, according to the preset channel configuration table, there are currently four handles H1, H2, H3 and H4 with established communication connections for data transmission using the channel. The configuration channel corresponding to each handle is divided into a corresponding configuration uplink channel and a corresponding configuration downlink channel.
H1 is correspondingly configured with a downlink channel as a No. 0 channel, is correspondingly configured with an uplink channel as 12 and has a frame number type corresponding to the handle as a first type; h2 is correspondingly configured with a downlink channel of 0 number, an uplink channel of 12 number and a frame number type corresponding to the handle of a second type; h3 is correspondingly configured with a downlink channel as a No. 1 channel, is correspondingly configured with an uplink channel as 13 and has a frame number type corresponding to the handle as a first type; h4 is configured with 1 number channel corresponding to the downlink channel, 13 number channel corresponding to the uplink channel, and the frame number type corresponding to the handle is the second type.
When the frame number of the current period is odd numbers such as 1, 3 and 5, the frame number type of the current period is a first type, and according to a preset channel configuration table, only the frame number types corresponding to the H1 and H3 handles are the first type, and then the H1 and H3 handles are determined as two first handles which are allowed to transmit data in the current period; and respectively sending the first data to be sent corresponding to H1 and H3 to H1 and H3 through configuration channels corresponding to H1 and H3, namely corresponding configuration downlink channels 0 and 1.
When the frame number of the current period is an even number, such as 2, 4, 6 and the like, the frame number type of the current period is a second type, and according to a preset channel configuration table, only the frame number types corresponding to the H2 handle and the H4 handle are the second type, the H2 handle and the H4 handle are determined as two second handles allowing data transmission in the current period; and respectively sending second data to be sent corresponding to H2 and H4 to H2 and H4 through configuration channels corresponding to H2 and H4, namely correspondingly configured downlink channels 0 and 1.
Meanwhile, the broadcast signal is sent to the first handles and the second handles, so that the first handles and the second handles adjust clocks according to the broadcast signal, and synchronous communication with the first handles and the second handles is achieved. After the clock is adjusted, the synchronous communication process of the first handle, the second handle and the fixed end of the DECT equipment is as follows:
when the frame number of the current period is odd numbers such as 1, 3 and 5, the frame number type of the current period is a first type, and according to a preset channel configuration table, only the frame number types corresponding to the H1 and H3 handles are the first type, and then the H1 and H3 handles are determined as two first handles which are allowed to transmit data in the current period; then H1 and H3 respectively send data to the fixed end of the DECT device, i.e. the DECT base station, through the corresponding configuration channels of H1 and H3, i.e. the corresponding configuration uplink channel 12 and channel 13.
When the frame number of the current period is an even number, such as 2, 4, 6 and the like, the frame number type of the current period is a second type, and according to a preset channel configuration table, only the frame number types corresponding to the H2 handle and the H4 handle are the second type, the H2 handle and the H4 handle are determined as two second handles allowing data transmission in the current period; then H2 and H4 respectively send data to the fixed end of the DECT device, i.e. the DECT base station, through the corresponding configuration channels of H2 and H4, i.e. the corresponding configuration uplink channel 12 and channel 13.
In the communication method in the prior art, data is sent from a channel to a handle uniquely corresponding to each channel in each period; and because 24 channels are divided into an uplink channel and a downlink channel which are respectively used for the data sending and receiving of the handle, the communication device can only be used by 12 handles at most, namely, the upper limit of the simultaneous communication is only 12. According to the method, the frame number type of the current period is obtained, and the handle allowing data transmission in the current period is determined according to whether the frame number type of the current period is the same as the frame number type corresponding to the handle, wherein the frame number type comprises a first type and a second type. The method can respectively send the data to different handles in the same channel and in periods with different frame number types. Thus, one channel can support the simultaneous use of two handles, so that the channel can be used by 24 handles at most, namely, the upper limit of the simultaneous conversation is up to 24. The scheme only adopts a time division multiplexing method, the same channel is supplied to different handles for use in periods with different frame number types, no change is made on hardware, and the method is not like the prior art: in order to raise the upper limit of the call, 2 radio modules are put into one fixed end of the DECT device.
