It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting. In addition, it should be noted that, for the convenience of description, only some but not all of the structures related to the present application are shown in the drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

1 is a schematic flowchart of a communication method of a communication terminal of the present application, FIG. 2 is a schematic structural diagram of a communication terminal and a base station in FIG. 1, and FIG. 3 is a communication between the communication terminal and the base station in FIG. Schematic diagram of timing. The communication method disclosed in this embodiment is applied to the communication terminal 11, the communication terminal 11 establishes a communication connection with the base station 12, and the communication terminal 11 transmits a communication signal to the base station 12.

As shown in FIG. 1, the communication method disclosed in this embodiment includes the following steps:

S101: preset a plurality of first time slots and a plurality of second time slots, where the first time slot and the second time slot are adjacently disposed, and send a communication signal to the base station in the first time slot.

The communication terminal 11 is preset with a plurality of first time slots t1 and a plurality of second time slots t2, and the first time slot t1 and the second time slot t2 are disposed adjacent to each other, as shown in FIG.

The communication terminal 11 sends a communication signal to the base station 12 in the first time slot t1, and the communication signal may specifically be a voice signal, a data signal or a signaling signal. Take the communication signal as a voice signal as an example:

The voice call service is initiated at the communication terminal 11, that is, the user presses the PTT of the communication terminal 11 (Push to When Talk, push-to-talk service), the communication terminal 11 detects the CACH (Common Announcement) broadcast by the base station 12. Channel, common broadcast channel) information, the idle channel allocated by the base station 12 is acquired by the CACH information, and the communication terminal 11 transmits a voice signal at the first time slot t1, for example, the communication terminal 11 transmits the voice signal F at the first time slot t1. It is assumed that the first time slot t1 of the base station 12 is an idle channel.

The communication terminal 11 needs to transmit a voice header (Hdr) to the base station 12 before transmitting the voice signal. Therefore, the communication terminal 11 transmits a complete voice signal, and the voice header needs to be transmitted first, and then the voice signal is transmitted.

S102: Detect whether a downlink signal is received from the base station in the second time slot.

Among them, the communication terminal 11 detects whether or not the downlink signal is received from the base station 12 in the second time slot t2. As shown in FIG. 3, the communication terminal 11 transmits the voice signal A at the first time slot t1, and detects whether or not the downlink signal is received from the base station 12 at the second time slot t2 adjacent to the first time slot t1. Alternatively, the communication terminal 11 transmits the voice signal F at the first time slot t1, and detects whether or not the downlink signal is received from the base station 12 at the second time slot t2 adjacent to the next first time slot t1.

If the communication terminal 11 does not detect the downlink signal of the base station 12 in the second time slot t2, the process proceeds to step S103, where the base station 12 is in the sleep state; if the communication terminal 11 detects the downlink signal of the base station 12 in the second time slot t2, The communication terminal 11 and the base station 12 communicate normally.

The base station 12 may be configured with a first timer and a second timer. The first timer is used to prevent the communication terminal 11 from occupying the channel resources of the base station 12 for a long time, and the second timer is used to calculate the time when the communication terminal 11 stops active. When the first timer exceeds the preset first time threshold, the base station 12 still receives the communication signal of the communication terminal 11, and the base station 12 forcibly stops forwarding the communication signal. The base station 12 starts a second timer when forwarding the communication signal. When the second timer exceeds the preset second time threshold, the base station 12 still does not receive the valid signal of the communication terminal 11, and the base station 12 enters the sleep state.

S402: Detect whether a downlink signal is received from the base station in the second time slot.

The technical content of the step S402 is basically the same as that of the above step S102, and details are not described herein again. When the communication terminal 11 does not detect the downlink signal of the base station 12 in the second time slot t2, it proceeds to step S403; if the downlink signal of the base station 12 is detected in the second time slot t2, the communication terminal 11 and the base station 12 communicate normally.

S403: Send a wake-up signal to the base station in a next first time slot adjacent to the second time slot.

The communication terminal 11 does not detect the downlink signal of the base station 12 in the second time slot t2, that is, the base station 12 is in the sleep state. In the next first time slot adjacent to the second time slot, the communication terminal 11 transmits a wake-up signal to the base station 12, i.e., the communication terminal 11 transmits a wake-up signal at the first time slot t3. When the base station 12 is in the sleep state, the communication terminal 11 generates a wake-up signal, and replaces the original voice signal of the first time slot t3 with the wake-up signal. The base station 12 receives a wake-up signal at time slot T1, which is delayed by 60 milliseconds than the first time slot t3 of the communication terminal 11. The base station 12 switches from the sleep state to the channel suspend state according to the wake-up signal, and transmits the CACH signal and the signal idle frame to the communication terminal 11. The communication terminal 11 transmits a voice header at the first time slot t5, and detects whether a downlink signal is received from the base station 12 at the second time slot t6. The base station 12 receives the voice header in time slot T3 and enters the time slot 1 forwarding state. After detecting the downlink signal of the base station 12 in the second time slot t6, the communication terminal 11 transmits a voice signal in the first time slot t7. Thereby, the communication terminal 11 wakes up the base station 12 successfully, and the communication terminal 11 communicates with the base station 12 normally.

As shown in FIG. 6, when the communication signal is a voice service, the communication terminal 11 transmits a voice header to the base station 12 in the first time slot t1, and detects whether or not the downlink signal is received from the base station 12 in the second time slot t2. The communication terminal 11 does not detect the downlink signal of the base station 12 in the second time slot t2, that is, the base station 12 is in the sleep state. In the next first time slot adjacent to the second time slot, the communication terminal 11 transmits a wake-up signal to the base station 12, i.e., the communication terminal 11 transmits a wake-up signal at the first time slot t3. The communication terminal 11 generates a wake-up signal, and replaces the original voice header of the first time slot t3 with the wake-up signal. The base station 12 does not receive the wake-up signal and is still in the dormant state, i.e., the communication terminal 11 has left the coverage of the base station 12. After transmitting the voice header in the first time slot t5, the communication terminal 11 detects whether or not the downlink signal is received from the base station 12 in the second time slot t6. The downlink signal of the base station 12 is not detected in the second time slot t6, and the communication terminal 11 stops transmitting the voice signal. Thereby, the communication terminal 11 fails to wake up the base station 12, and the communication terminal 11 disconnects from the base station 12.

As shown in FIG. 7, when the communication signal is a data service or a signaling service, the communication terminal 11 transmits a pre-carrier to the base station 12 in the first time slot t1, and detects whether a downlink signal is received from the base station 12 in the second time slot t2. . The communication terminal 11 does not detect the downlink signal of the base station 12 in the second time slot t2, that is, the base station 12 is in the sleep state. In the next first time slot adjacent to the second time slot, the communication terminal 11 transmits a wake-up signal to the base station 12, i.e., the communication terminal 11 transmits a wake-up signal at the first time slot t3. The communication terminal 11 generates a wake-up signal, and replaces the original pre-carrier of the first time slot t3 with the wake-up signal. The base station 12 receives a wake-up signal at time slot T1, which is delayed by 60 milliseconds than the first time slot t3 of the communication terminal 11. The base station 12 switches from the sleep state to the channel suspend state according to the wake-up signal, and transmits the CACH signal and the signal idle frame to the communication terminal 11. The communication terminal 11 transmits the pre-carrier at the first time slot t5, and detects whether or not the downlink signal is received from the base station 12 at the second time slot t6. The base station 12 receives the pre-carrier in time slot T3 and enters the time slot 1 forwarding state. After detecting the downlink signal of the base station 12 in the second time slot t6, the communication terminal 11 transmits the pre-carrier in the first time slot t7. Thereby, the communication terminal 11 wakes up the base station 12 successfully, and the communication terminal 11 communicates with the base station 12 normally.

Through the above communication method, the communication terminal 11 detects the downlink signal of the base station 12 at the start of communication, and if the downlink signal of the base station 12 is not detected, the communication terminal 11 attempts to wake up the base station 12 in the next first time slot; if still not detected When the downlink signal of the base station 12 is stopped, the communication terminal 11 stops transmitting the communication signal, and can effectively prevent the communication terminal 11 from continuing to transmit the communication signal when the base station 12 is in the sleep state, thereby preventing the communication terminal 11 from losing the communication data.

Referring to FIG. 8 and FIG. 9 , FIG. 8 is a schematic flowchart of Embodiment 3 of a communication method of a communication terminal of the present application; FIG. 9 is a timing diagram of a data retransmission of Embodiment 3 of the communication method of FIG. 8 . .

As shown in FIG. 8, the communication method disclosed in this embodiment includes the following steps:

S801: preset a plurality of first time slots and a plurality of second time slots, where the first time slot and the second time slot are adjacently disposed, and send a communication signal to the base station in the first time slot.

The technical content of the step S801 is basically the same as that of the above step S101, and details are not described herein again.

S802: Detect whether a downlink signal is received from the base station in the second time slot.

The technical content of the step S802 is basically the same as that of the foregoing step S102, and details are not described herein again. When the communication terminal 11 does not detect the downlink signal of the base station 12 in the second time slot t2, it proceeds to step S803; when the downlink signal of the base station 12 is detected in the second time slot t2, the communication terminal 11 normally communicates with the base station 12.

S803: Send a wake-up signal to the base station in a next first time slot adjacent to the second time slot.

The technical content of the step S803 is basically the same as that of the above step S403, and details are not described herein again.

S804: Query the channel access status.

The communication terminal 11 queries the channel access status of the base station 12. The channel access status of base station 12 may include a sleep state, a channel idle state, and a channel busy state. If the base station 12 is in a dormant state, the base station 12 does not forward the uplink call signal. At the same time, the base station 12 can receive the valid wake-up signal from the communication terminal 11 and exit the sleep state according to the wake-up signal. After the base station 12 is successfully awake, the base station 12 detects whether the channel is in an idle state or a busy state. When the channel of the base station 12 is in the channel suspend state, the base station 12 is in the channel idle state; when the channel of the base station 12 is occupied by the other communication terminal 11, the base station 12 is in the channel busy state.

When the channel of the base station 12 is idle or the base station 12 wakes up successfully, the channel of the base station 12 is idle, and the process proceeds to step S805. When the base station 12 wakes up or the channel of the base station 12 is busy, it proceeds to step S806.

S805: Send a communication signal to the base station in the first time slot.

When the channel of the base station 12 is idle or the base station 12 wakes up successfully, the channel of the base station 12 is idle, and the communication terminal 11 transmits data or signaling traffic to the base station 12 in the first time slot.

S806: Stop transmitting the communication signal to the base station in the first time slot, and determine whether the communication signal needs to be retransmitted.

When the base station 12 fails to wake up or the channel of the base station 12 is busy, the communication terminal 11 stops transmitting the communication signal to the base station 12 in the first time slot, and determines whether the communication signal needs to be retransmitted.

When the communication terminal 11 determines that the communication signal does not need to be retransmitted, the process proceeds to step S808, for example, the communication terminal 11 receives an instruction not to retransmit; when the communication terminal 11 determines that the communication signal needs to be retransmitted, the process proceeds to step S807, for example, the communication terminal. 11 Received a retransmission instruction.

S807: Determine whether the number of retransmissions is greater than zero.

When the communication signal needs to be retransmitted, the communication terminal 11 determines whether the number of retransmissions is greater than zero, wherein the communication terminal 11 determines whether the number of retransmissions is greater than zero through the communication protocol; and if the communication terminal 11 determines that the number of retransmissions is greater than zero, the communication terminal 11 The transmission of the communication signal to the base station 12 in the first time slot is stopped and retransmission is performed. For example, the communication terminal 11 saves the node when the communication signal fails to be transmitted, and retransmits the communication signal corresponding to the node at the time of retransmission. The communication terminal 11 decrements the number of retransmissions by one retransmission and saves the number of retransmissions after the update.

If the communication terminal 11 determines that the number of retransmissions is not greater than zero, for example, the number of retransmissions is zero, the process proceeds to step S808.

S808: Stop transmitting the communication signal to the base station in the first time slot.

Wherein, if the communication terminal 11 determines that the communication signal does not need to be retransmitted or the number of retransmissions is not greater than zero, the communication terminal 11 stops transmitting the communication signal to the base station 12 in the first time slot.

As shown in FIG. 9, in the process of transmitting a communication signal of a data service or a signaling service, the communication terminal 11 transmits a data block to the base station 12 at the first time slot t1. The communication terminal transmits a data block to the base station 12 at the first time slot t3, and detects whether a downlink signal is received from the base station 12 at the second time slot t4. The downlink signal of the base station 12 is not detected in the second time slot t4, that is, the base station 12 is in the sleep state, and the communication terminal 11 stops transmitting the data block. The communication terminal 11 determines whether it is necessary to retransmit the data service or the signaling service; if retransmission is required, the communication terminal 11 queries the number of retransmissions in the communication protocol; if the number of retransmissions is greater than zero, the communication terminal retransmits the data service or the signaling service. The communication terminal 11 sends a wake-up signal to the base station 12 in the first time slot t5 to query the channel access state of the base station 12. When the channel of the base station 12 is idle or the base station 12 wakes up successfully, the channel of the base station 12 is idle, and the communication terminal 11 transmits the pre-carrier to the base station 12 at the first time slot t7. The first time slot t5 and the first time slot t7 may include a plurality of first time slots and a plurality of second time slots. The base station 12 receives the wake-up signal and switches from the sleep state to the channel suspend state according to the wake-up signal. The base station 12 receives the pre-carrier in time slot T5 and the base station 12 enters the normal forwarding state. The time slot T5 is delayed by 60 milliseconds than the first time slot t7 of the communication terminal 11. After the communication terminal 11 receives the downlink signal from the base station, the communication terminal 11 and the base station 12 communicate normally.

Through the above communication method, the communication terminal 11 detects the downlink signal of the base station 12 at the start of communication, and if it detects that the downlink signal is not received from the base station 12, the communication terminal 11 attempts to wake up the base station 12 in the next first time slot; When the downlink signal of the base station 12 is detected, the communication terminal 11 starts the data retransmission process; when the communication terminal 11 receives the unnecessary data retransmission command or allows the number of retransmissions to be zero, the communication terminal 11 stops transmitting the communication signal; The communication terminal 11 retransmits the communication signal when the base station 12 is in a sleep state or the channel is busy, preventing the communication terminal 11 from losing communication data.

Referring to FIG. 10, FIG. 10 is a schematic flowchart of Embodiment 4 of a communication method of the communication terminal 11 of the present application. The communication terminal 11 changes from the coverage of the original base station 12 to the coverage of the new base station 12, thereby implementing active roaming services. The communication method includes the following steps:

S110: preset a plurality of first time slots and a plurality of second time slots, where the first time slot and the second time slot are adjacently disposed, and send a communication signal to the base station in the first time slot.

S111: Detect whether a downlink signal is received from the base station in the second time slot.

S112: Stop transmitting the communication signal to the base station in the first time slot.

The technical features of the steps S110, S111, and S112 are substantially the same as those of the foregoing steps S101, S102, and S103, and are not described herein again.

S113: Start an active roaming service, acquire other base station information, and communicate with the new base station.

The communication terminal 11 initiates an active roaming service, acquires new base station 12 information, and communicates with the new base station 12. Specifically, when the communication terminal 11 initiates the active roaming service, the communication terminal 11 stops transmitting the communication signal to the original base station 12, and searches for a new base station 12 to establish a communication connection, and restarts the process of transmitting the communication signal.

Through the above communication method, the communication terminal 11 detects the downlink signal of the base station 12 during the communication start or communication, and if the downlink signal of the base station 12 is not detected, the communication terminal 11 stops transmitting the communication signal to the base station 12 in the first time slot. The active roaming service is started to communicate with the new base station 12; the communication terminal 11 stops transmitting the communication signal when the original base station 12 is in the sleep state, and connects the new base station 12 to restart the process of transmitting the communication signal.
