Method and terminal for communicating based on distributed cluster communication system

This application claims priority to Chinese Patent Application No. 201410117600.6, entitled "Method and Terminal for Communication Based on Distributed Cluster Communication System", filed on March 26, 2014, the entire contents of which is filed on March 26, 2014. This is incorporated herein by reference.

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and terminal for communicating based on a distributed trunking communication system.

Background technique

In a conventional wireless communication system, a user terminal can only communicate on its assigned channel. The conventional walkie-talkie wireless communication system of FIG. 1, wherein the user of the communication group 1 is pre-assigned to communicate on the channel 1, that is, the user of the communication group 1 cannot communicate using the channel 2 or the channel 3, so the conventional wireless The channels in the communication system are fixedly assigned to specific users, and the system can only support a limited number of calling users.

The trunking communication system implements a multi-user shared multi-channel radio mobile communication system in accordance with a dynamic channel assignment manner, and the trunking communication system can solve the problem of the conventional wireless communication system. The trunking communication system is generally composed of a terminal device, a base station, a control management center, and the like, and has functions of scheduling, group calling, priority calling, virtual private network, and roaming. Referring to FIG. 2, FIG. 2 is a schematic diagram of a trunking communication system in the prior art, which includes a plurality of walkie-talkie users, a control management center, a plurality of traffic channels, and a control channel. In the trunking communication system, the walkie-talkie user needs to be powered on and successfully registered in the cluster communication system to communicate. When the walkie-talkie needs to communicate, firstly, a communication request is sent to the control management center on the control channel, and then waits for control management. After the center allocates a traffic channel to it, and the control management center allocates a traffic channel for it, the walkie-talkie can switch to the traffic channel for communication. It can be seen that in the trunking communication system, the walkie-talkie must take a long time to establish a call before communicating, and at the same time, the entire communication process must involve the control management center, and in the actual communication system, the control management center has a higher construction cost. This also leads to the problem of high construction cost of the trunking communication system.

In order to overcome the above drawbacks, a distributed trunking communication system with a relay station gradually replaces the trunking communication system with the control management center, and the relay station of the distributed trunking communication system replaces The status of the base station and control management center in the trunking communication system. How to use the resources of the current distributed trunking communication system to improve channel utilization and support more call users without increasing the cost is our most concerned issue.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Referring to FIG. 3, FIG. 3 is a flowchart of a method for performing communication based on a distributed trunking communication system according to an embodiment, where the distributed trunking communication system includes at least one station, where the station includes at least one relay station and multiple user terminals. Each repeating station includes a plurality of logical channels, and the method may include:

S301: The distributed trunking communication system allocates a primary repeater to a user terminal in the site according to a preset allocation policy.

The solution of the embodiment of the present invention is implemented by using a distributed cluster communication system, which may be a single-station distributed cluster communication system or an IP-connected multi-station distributed cluster communication system, that is, the distributed cluster. The communication system may include a single site or multiple sites. The user terminal described in this embodiment may be a walkie-talkie.

In a practical application, the relay station and the user terminal of the distributed trunking communication system can store the allocation policy, and the allocation policy can be a correspondence between the transit station and the user terminal. After the user terminal accesses the distributed cluster communication system, The user terminal and the relay station can respectively establish a correspondence according to the respective stored allocation policies, that is, determine the main relay station for the user terminal. In addition, the allocation of the primary repeater of the user terminal can be realized by storing only the allocation policy in the relay station of the distributed trunking communication system. That is to say, the user terminal does not need to store the allocation policy. Specifically, when the user terminal accesses the distributed trunking communication system, the user terminal may receive a message broadcast by the relay station, and when the user terminal receives the allocation policy associated with the user terminal, the allocation policy may be stored in the The user terminal, and in turn, the transfer station and the user terminal can complete the assignment of the primary repeater according to the respective stored allocation policies.

Each station in the distributed trunking communication system includes at least one channel frequency point, and each channel frequency point can serve as a relay station, and the distributed trunking communication system pre-sets the user terminal in the station according to a preset allocation policy. Assign the main repeater. The pre-set allocation policy is a balanced allocation strategy, that is, the number of allocated user terminals on each repeater is as close as possible. Same When a channel frequency point can be divided into multiple logical channels (also known as time slots), a specific channel frequency point can be divided into several logical channels determined by a protocol used by actual communication, such as DMR (Time Division Multiple Access Dual) Slot channel) Protocol, each channel can be divided into two logical channels. Similarly, if a time division multiple access four-slot channel protocol is used, each channel can be divided into four logical channels. The logical channel divided by the channel frequency is specifically used for communication of the user terminal. When the logical channel is used for communication, the logical channel is in a busy state at this time. Conversely, when the logical channel is not used for communication, the logic is The channel is in an idle state. The use of logical channels enables one frequency point to simultaneously perform multiple calls, improving channel utilization.

S302: The user terminal monitors a primary repeater station that is pre-assigned to the user terminal.

In this embodiment, the user terminal locked with any one of the distributed trunking communication systems is assigned a relay station as the primary relay station in advance. Among them, the main repeater includes multiple logical channels. The user terminal preferentially listens to the main repeater of the user terminal.

When the distributed trunking communication system includes a communication group, the primary relay station can be equally allocated to different communication groups according to a preset equalization allocation policy, and at the same time, the user terminals included in each communication group are pre-allocated in the same primary relay station. on. Wherein each communication group includes at least two user terminals. Specifically, when the number of communication groups is not greater than the number of the transfer stations, the preset equalization allocation policy may be to allocate different main transfer stations for each communication group; in addition, when the number of communication groups is greater than the number of the transfer stations, The preset balanced allocation strategy may be that the number of distribution groups allocated on each primary repeater is not much different.

S303: When any user terminal triggers communication, determining whether the primary relay station of the user terminal that triggers the communication has an idle logical channel, and when the primary relay station of the user terminal has an idle logical channel, using the idle The logical channel communicates.

In this embodiment, when any one of the user terminals triggers communication, the user terminal first determines whether there is an idle logical channel of the primary relay station of the user terminal, and when there is an idle logical channel on the primary relay station, the primary is used. The idle logical channel of the repeater communicates.

In practical applications, it is possible to determine whether there is an idle logical channel of the main relay station of the user terminal according to the CACH information of the radio frequency signal sent by the relay station. Referring to Table 1, Table 1 is a 24-bit CACH information structure diagram in the radio frequency signal, where AT (Access Type) is used to indicate whether the state of the logical channel is busy or idle; TC (Time Division Multiple Access Channel, TDMA Channel) A slot number indicating a time division multiple access channel, where the slot number is a logical channel number, used to indicate Specifically, which one of the plurality of logical channels, LCSS (Link Control Start/Stop) indicates the start or end of the communication.

Table 1

For example, as shown in Table 1, the specific determination process of determining whether the primary repeater of the user terminal has an idle logical channel may be as follows: Each channel includes two logical channels. In this way, the radio frequency signal sent by the main relay station of the user terminal includes two CACH information, which respectively correspond to two logical channels included in the main relay station, and when the strength of the radio frequency signal is greater than a preset threshold, The user terminal can determine whether there is an idle logical channel in the main repeater according to the value of the AT bit in the CACH information. According to the ETSI-DMR standard, if the AT bit is set to 1, it indicates that the indicated logical channel is busy, that is, The repeater is relaying voice communication or data transmission initiated by other terminals than the user terminal. If the AT bit is set to 0, it indicates that the status of the indicated logical channel is idle, that is, the repeater does not transfer any voice. Communication or data transmission, but an idle frame is being sent to indicate that the user terminal can Since communication.

If the AT bits in both CACH information are 1, it means that the primary repeater has no idle logical channel available. If one of the two bits in the CACH information is not 1, it indicates that the primary repeater is available. Idle logical channel; after the user terminal determines that there is an idle logical channel in the primary relay station according to the AT bit in the CACH information, further, the user terminal can determine which logical channel state is based on the TC bit in the corresponding CACH information. If idle, the user terminal communicates using the idle logical channel.

In this embodiment, the logical channel included in the primary relay station of the user terminal may be divided into a primary channel and a secondary channel, where one primary relay station corresponds to one primary channel, and the other logical channels are referred to as secondary channels. When the user terminal triggers communication, first determining whether the primary channel in the primary relay station of the user terminal is in an idle state, and if the primary channel is in an idle state, the user terminal uses the primary channel to communicate; otherwise, determining Whether the primary relay station of the user terminal has an idle auxiliary channel, and the user terminal uses an idle auxiliary channel for communication.

In practical applications, members of the same communication group are usually assigned to the same relay station, and the plurality of logical channels included in the relay station are respectively used as the primary channel. In this embodiment, any one of the relay stations including the idle logical channel is determined as the free transit station of the distributed trunking communication system. Each distributed trunking communication system includes only one free repeater station, and the free repeater station includes at least one idle logical channel.

When the primary relay station of the user terminal does not have an idle logical channel, the user terminal communicates using the idle logical channel of the free relay station, and the use of the free relay station can further support more call users.

The present invention can support not only a single site system but also a multi-site system. For multi-site systems, the present invention only requires the use of IP to connect the repeaters in different sites.

In this embodiment, the user terminal detects whether the radio frequency signal sent by the main relay station is less than a preset threshold. If the radio frequency signal sent by the main relay station is less than the preset threshold, the main transit station enters a sleep state. The user terminal sends a wake-up signal to wake up the main repeater. The user terminal starts the wake-up timer while transmitting the wake-up signal, and the wake-up timer is recorded as the first timer. If the feedback signal sent by the main repeater is received before the first timer expires, the main terminal is indicated. The relay station is successfully awake, wherein the feedback signal indicates the idle logical channel available to the user terminal, and the user terminal uses the idle logical channel to communicate, and the feedback signal is the idle frame.

If the feedback signal sent by the primary repeater is not received before the first timer expires, it indicates that the user terminal fails to wake up. At this point, the user terminal can communicate using any of the free logical channels of the free repeater.

If the free repeater is also in a sleep state, the user terminal may send a wake-up signal to wake up the free repeater, and after the free repeater is successfully awake, the user terminal uses the free repeater Any idle logical channel communicates.

When all of the logical channels in the distributed trunking communication system are in a busy state, the user terminal preferentially listens to the primary repeater of the user terminal.

In a practical application, when the user terminal is listening to its own primary repeater, it may detect that another repeater forwards the call of the user terminal. At this time, the user terminal may use the repeater that is forwarding the call. The call.

When the call accessed by the user terminal ends, the user terminal may detect whether its own primary relay station has an idle logical channel, and if so, the user terminal preferentially listens to the primary relay station. The following is an example of single-site cluster communication with DMR time division multiple access, and a method based on communication is specifically introduced. Referring to FIG. 4, FIG. 4 is a single-site structure diagram, and the following is a method for communication based on the system in FIG.

When walkie-talkie users are active within the coverage of a single site, each walkie-talkie user has priority to listen to their own primary repeater. In the station 1 of FIG. 4, the main repeater assigned to the walkie-talkies G1, G2, and G3 is the F1 frequency point (the frequency point is the repeater), and the main repeater assigned to the walkie-talkies G4, G5, and G6 is the F2 frequency point. The main repeater assigned to the walkie-talkies G7, G8, and G9 is the F3 frequency point.

When the user of G1 initiates a call at time slot 1 (slot, ie logical channel) of the F1 frequency point, and the user of G2 initiates a call at time slot 2 of the F1 frequency point, the user of G3 will detect two of the main transfer station. The time slots are occupied. At this time, the user of G3 switches to the free relay station F2 to listen to the station broadcast message. Users of G4, G5 and G6 continue to listen to its main repeater F2, G7, G8 and G9 users still stay on its main repeater F3.

As shown in Figure 4, the single-site distributed trunking communication system can support 6 calls simultaneously in a single station with 3 channels, compared with the existing one frequency point, which can only allocate two calls for the intercom. It can support 6-way calls at the same time, and the probability that all channels are busy is small, so the possibility of calls being accessed is greatly increased, and the number of users supporting calls is also increased.

The following is an example of a DMR time division multiple access IP interconnection multi-site distributed cluster communication system, and a method for communication based on a distributed cluster communication system is introduced. Referring to FIG. 5, FIG. 5 is a structural diagram of a multi-site distributed cluster communication system, A method of communicating based on the system in FIG.

When the walkie-talkie is applied in the DMR time division multiple access virtual cluster system, two logical channels will be added for each additional channel frequency. Station 1 of Fig. 5 includes two frequency points F1 and F2, and their logical channels are time slot 1, time slot 2, time slot 3, and time slot 4, respectively. Site 2 includes two frequency points, F3 and F4, whose logical channels correspond to the logical channel time slots of station 1. If a group of users frequently moves between more than two sites, it will assign different primary repeaters at different sites. For example, the group 1 user is the F1 in the main transit station of the site 1, and the main transit station in the site 2 is the F3. When the group 1 user is active on the site 1, the main transit station F1 is preferentially monitored, and when it moves to the site 2, The primary repeater that listens first is switched to F3.

As shown in Figure 5, in Site 1 and Site 2, each site's logical channel can support a single call. Walkie-talkie user A initiates a group call of call group 1 in slot 1 of station 1. Group members in Fl and group members moving to F3 will receive calls. When the walkie-talkie B initiates a call, if the time slot 1 is already occupied, the walkie-talkie B will use the idle time slot 2 to make a call. Similarly, time slot 3 and time slot 4 can also be used to support different calls.

At the same time, the newly-on user can search for the activity of interest by receiving the station broadcast message, for example: the member of group 1 is powered on at the F4 frequency, and the call of the time slot 1 in the forwarding group 1 is detected by receiving the broadcast message of the station, group 1 The member switches to the F3 frequency point to access the call of group 1 in time slot 1.
