Description

Channel processing method and device, electronic device

Technical field

The present invention relates to the field of communications, and in particular to a channel processing method and device, and an electronic device.

Background technique

In DMR (Digital Mobile Radio) or PDT (Public Digital Truking, public digital trunking) communication systems, in order to expand the communication range of mobile terminals, a BS is usually set up to relay signals from the mobile terminal. For a BS (Base Station) with multiple channels, the following evolutions in managing these channels:

Dedicated control channel mode: The BS divides one or more channels from the channels as fixed control channels, and other channels are used as traffic channels. The signaling issued by the BS on the control channel and the traffic channel will be different, and the terminal will use these differences. Distinguish whether it is a control channel or a traffic channel. In the idle state, the terminal stays in one of the control channels, and the BS implements communication handshake and scheduling for the terminal through one or more control channels. When a terminal applies for a service, the BS allocates a service channel to the terminal for service communication; when the terminal releases the service, the base station reclaims the service channel. This technical advantage is to ensure the sharing and dynamic allocation of service channels. The disadvantage is that one or more fixed control channels need to be divided from the channel to complete the communication handshake and scheduling between the base station and the terminal, resulting in the change of the traffic channel that can be communicated. less.

Composite control channel mode: The European Telecommunications Standards Institute-Digital Mobile Radio (ETSI-DMR) standard (ETSI TS 102 361-4) improves mode 1, and proposes a composite control channel mode, that is, when the traffic channels are all allocated, The remaining terminals applying for service again will convert the current control channel into a service channel for use. The disadvantage is that these composite control channels are fixed. When all composite control channels are converted to service channels, there will be no control channels. Only when these composite control channels release services can they be converted back to control channels. Perform communication handshake and scheduling for the terminal.

The composite control channel method is improved on the basis of the dedicated control channel method, but it is still not perfect. The disadvantage is that if the service is not released for a long time when the composite control channel is converted to a traffic channel, it will lead to a long time without a control channel. During this period of time, communication handshake and scheduling to the terminal can no longer be performed.

In view of the above-mentioned problems in related technologies, there is currently no effective solution.

For example, the mobile terminal 10 may also include more or fewer components than those shown in FIG. 1, or have a different configuration from that shown in FIG.

The memory 104 may be configured to store computer programs, for example, software programs and modules of application software, such as the computer programs corresponding to the channel processing method in the embodiment of the present invention. The processor 102 runs the computer programs stored in the memory 104, thereby Perform various functional applications and data processing, that is, realize the above-mentioned methods. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely provided with respect to the processor 102, and these remote memories may be connected to the mobile terminal 10 via a network. Examples of the aforementioned networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

The transmission device 106 is configured to receive or transmit data via a network. The above-mentioned specific example of the network may include a wireless network provided by the communication provider of the mobile terminal 10. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, NIC for short), which can be connected to other network devices through a base station to communicate with the Internet. In an example, the transmission device 106 may be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet in a wireless manner.

In this embodiment, a method for processing a channel operating in the above network architecture is provided. Fig. 2 is a flowchart of a method for processing a channel according to an embodiment of the present invention. As shown in Fig. 2, the process includes the following steps:

Step S202: The communication node judges whether any occupied service channel is released;

Step S204, in the case that any occupied service channel is released, the communication node determines whether to convert the released service channel into a control channel according to whether there is a control channel.

Through the above steps S202 and S204, when any occupied service channel is released, the communication node will determine whether to convert the released service channel to a control channel according to the situation, thereby solving the problem of the composite control channel conversion in the related technology. If the service channel is not released for a long time when it becomes a service channel, it will cause the problem of too long without a control channel, shorten the time without a control channel, and ensure the communication and scheduling of the terminal.

Optionally, the communication node of the execution subject of the foregoing steps may be a base station, but is not limited to this.

In an optional implementation manner of this embodiment, the communication node involved in step S204 of this embodiment determines whether to convert the released traffic channel into a control channel according to whether there is a control channel, which may be:

Step S204-11, the communication node judges whether there is a control channel in the current channel;

Step S206-12, when there is no control channel in the current channel, the communication node converts the released traffic channel into a control channel;

Step S206-13: In the case that there is a control channel in the current channel, the communication node determines whether to convert the traffic channel to the control channel according to a preset condition.

That is to say, when a service channel is released, the communication node first needs to determine whether there is a control channel currently. If there is no control channel, it needs to convert the released service channel to a control channel to ensure that there is at least one control channel in the channel. ; If there is currently a control channel, the communication node will determine whether to convert the released service channel to a control channel according to the specific application situation. For example, if there are many current control channels and there are still idle states, the conversion may not be necessary, or although There is a control channel currently, but the current demand cannot be met, and the traffic channel needs to be converted to a control channel to meet the demand.

In an optional implementation manner of this embodiment, after the traffic channel is converted to a control channel, the method of this embodiment may further include:

Method 1: The communication node informs the terminal in the service channel to switch to the control channel converted from the service channel after the service ends;

Method 2: The communication node judges whether the control channel of the terminal in the idle state is consistent with the control channel currently converted from the service channel; if the judgment result is yes, the communication node informs the terminal in the idle state that the service is available On the control channel for channel switching; in the case of a negative judgment result, the communication node informs the terminal in an idle state to switch to the control channel switched by the traffic channel.

Through the above-mentioned method 1 and method 2, the terminal that is in the service channel and is performing service is notified to return to the new control channel when the service ends and releases the channel. For a terminal that has no service on the original control channel, because the original control channel has been converted to a service channel, it is necessary to determine whether the new control channel is the same as the old one. If they are the same, the terminal does not need to switch; if they are different, the terminal can be Switch to a new control channel or scan to a new control channel according to traffic channel signaling.

In an optional implementation manner of this embodiment, the method of this embodiment may further include:

Step S206, the communication node receives the service request initiated by the terminal;

Step S208, the communication node judges whether all current service channels have been allocated;

Step S210, in the case that the judgment result is no, the communication node selects an unallocated service channel to the terminal;

Step S212: In a case where the judgment result is yes, the communication node converts the control channel into a traffic channel, and allocates the traffic channel converted by the control channel to the terminal.

Hereinafter, the above-mentioned step S202 to step S212 in this embodiment will be described with an example in combination with an optional implementation manner of this embodiment;

In this optional implementation, if all control channels have been converted to traffic channels, when any traffic channel is free, it will be converted to control channels immediately. In this case, the composite control channel method can only wait for the fixed composite The business of the control channel can only be converted to the disadvantage of the control channel when the service is idle, which shortens the time without a control channel.

For the dynamic control channel method, the BS has six channels as an example. According to service requirements, one channel needs to be allocated as a control channel and 5 channels as a service channel. Fig. 3 is a flowchart of a method for dynamically controlling a channel according to an embodiment of the present invention. As shown in Fig. 3, the steps of the method include:

Step S301, the terminal needs to perform service communication to initiate a service request;

In step S302, the BS determines whether the 5 traffic channels have been allocated; if the determination result is no, execute step S303; if the determination result is yes, execute step S304;

Step S303: Allocate one of the service channels to the terminal for communication;

Step S304: Convert the current control channel to a traffic channel and allocate it to the terminal for communication;

Step S305: Notify the terminal that the current control channel has been converted to a traffic channel.

In step S306, the terminal is notified that the service application is successful.

In addition, if all control channels have been converted to service channels, the terminal staying on the original control channel cannot initiate any service applications. At this time, it is necessary to convert the service channels to control channels as soon as possible. When any service channel is released Switch to the control channel immediately. Fig. 4 is a flowchart of a method for converting a traffic channel into a control channel according to an embodiment of the present invention. As shown in Fig. 4, the steps of the method include:

Step S401: When a terminal on any service channel (including the original control channel converted to a service channel) initiates a request to release the current service channel or the BS terminates the current service channel;

In step S402, the BS determines whether the current traffic channel needs to be converted to a control channel; if the determination result is yes, execute step S403; if the determination result is no, execute step S404;

Among them, it is necessary to ensure at least one control channel. When there is no control channel, the traffic channel must be converted to a control channel. When there is a control channel, the BS determines according to the application;

Step S403, if yes, release the current traffic channel;

Step S404, if not, convert the current traffic channel to a control channel;

Step S405, informing the terminal that the current traffic channel has been converted to a control channel;

Step S406, end.

Figure 5 is a flowchart of a method for notifying a terminal that a traffic channel has been converted to a control channel according to an embodiment of the present invention. A control channel, the steps of the method include:

Step S501, notifying that the current traffic channel has been converted to a control channel.

Step S502: It is judged whether the terminal is a terminal performing services on a traffic channel or a terminal staying on an old control channel in an idle state.

Step S503: For the terminal (including the terminal currently converted to the control channel) that is in the service channel and is performing the service, the terminal is notified to return to the new control channel when the BS releases the channel when the service ends.

Step S504: For a terminal that has no service on the original control channel, because the original control channel has been converted to a service channel, it is necessary to judge whether the new control channel is the same as the old one;

Step S505, if the same, the terminal does not need to switch;

In step S506, if they are different, the terminal can switch to a new control channel or scan to a new control channel according to the traffic channel signaling.

It can be seen that based on Figures 4 and 5, that is, when there is no control channel or the control channel is insufficient, any traffic channel released will immediately be converted to a control channel, which shortens the time of no control channel or insufficient control channel.
