Description

Communication method, device, equipment and storage medium

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a communication method, apparatus, device, and storage medium.

Background

In private network communication, the call uses the highest frequency point function, so that the user work efficiency and user experience can be greatly improved by establishing friendly and efficient call. In the conventional transfer mode, if after the communication terminal sends the activation frame for the maximum number of times to the transfer station in the process of accessing the transfer station, or after the transfer call is established successfully (the communication terminal is successfully accessed to the transfer station), the situation that the communication terminal moves and exceeds the coverage area of the transfer station, or the transfer station drops, etc., can result in that the mobile terminal cannot receive the valid frame of the downlink of the transfer station, the current sending of the communication terminal is refused (the transfer call fails), and is regarded as an invalid call, and the service fails.

At present, when the middle rotary table cannot work normally, the following two processing modes exist: one is to cancel the communication, wait until the transfer platform can work normally, and then re-initiate the call request; the other is to cancel the current communication and switch the communication terminal initiated by the service (i.e. the calling terminal) to the through mode, i.e. the calling terminal and the target terminal sent by the service (i.e. the called terminal) adopt the direct communication mode (abbreviated as the through mode) without going through the relay platform to carry out service communication. In order to ensure the success rate of the service, a second processing mode is mostly adopted in the current communication field, namely, the calling terminal is switched to the direct mode to try communication, and the method mainly comprises two switching schemes of manual switching and automatic switching in practical application. For the manual switching scheme, the user needs to manually switch, the noninductive switching can not be smoothly realized, the operation is complex, and for the automatic switching scheme, the switching is immediately performed to the through mode as long as the calling terminal detects the transfer call failure, whether the called terminal can receive the through call can not be determined, and when the called terminal can not receive the through call, the channel resource waste can be caused because the calling terminal occupies the channel.

Example 1

Referring to fig. 1, the present embodiment provides a communication method that can be applied to a communication system including a communication terminal (e.g., interphone, mobile phone, etc.) and a transom, and the present embodiment describes an example in which the method is applied to a calling terminal in the communication terminal, specifically, the method includes the steps of:

s110, when a transfer call connection transfer platform is failed to be initiated in a first transfer mode, switching to a first through mode and sending a call request outwards, wherein the call request comprises call mode information of a calling terminal, the first transfer mode takes a first initial frequency point as a sending frequency point and takes a second initial frequency point as a receiving frequency point, and the first through mode takes the second initial frequency point as the sending frequency point and the receiving frequency point.

In this embodiment, the initial communication mode of the communication terminal is a first transfer mode, in the first transfer mode, the communication terminal sends a signal to the transfer station (which refers to a device capable of implementing a transfer function, or may be a base station, which is not limited in the present application), and receives a signal from the transfer station with the second initial frequency point as a receiving frequency point (it should be noted that, the first initial frequency point and the second initial frequency point are two frequency points that are set in advance, and the transfer station takes the second initial frequency point as a sending frequency point and the first initial frequency point as a receiving frequency point in a default working state), that is, when a user initiates a call using the communication terminal (for example, the user presses a call button of the mobile phone, sends a call voice instruction to the mobile phone, etc.), the communication terminal immediately generates an activation frame and sends the activation frame to the mobile station through the sending frequency point, and the activation frame is information for activating the transfer station generated by the calling terminal. After the calling terminal sends the activation frame, detecting whether an effective frame returned by the transfer station according to the activation frame is received, wherein the effective frame is information which is generated by the transfer station and used for confirming that the transfer station is communicated with the communication terminal. In this embodiment, after receiving the activation frame, the transit station generates an active frame if the activation is successfully completed, and transmits the active frame to the calling terminal according to the receiving frequency of the downlink channel, otherwise, if the activation of the transit station fails due to the reason that the calling terminal exceeds the communication coverage area of the transit station and the transit station fails (the transit station does not receive the activation frame and is regarded as the activation failure), a call request is sent to the outside through modes such as paging and broadcasting (the sending mode can be set by itself according to different actual requirements and is not limited here). More specifically, in some embodiments, the relay station is activated successfully, where the calling terminal and the called terminal are both in the first relay mode, and both establish relay communication by means of the relay station, where the relay communication is that the calling terminal and the called terminal establish communication service by means of the relay station, that is, after detecting a valid frame returned by the relay station, the calling terminal initiates a call connection with a specified communication terminal (that is, the called terminal) to the relay station, and the relay station establishes relay communication between the calling terminal and the called terminal according to the relay communication, that is, the call service is successful.

In this embodiment, the call request is request information generated for the calling terminal for verifying whether the called terminal can receive the through call. In this embodiment, in order to avoid that, when a calling terminal initiates a through call, a channel resource is wasted due to the fact that a called terminal cannot receive the through call of the calling terminal because of too far distance (refer to the distance between the called terminal and the calling terminal), before the calling terminal communicates with the called terminal in the through mode, a call request is generated by the calling terminal and sent outwards, and after the called terminal receives the call request, it is verified whether the called terminal can communicate with the calling terminal in the through mode. Meanwhile, the called terminal sends a confirmation message according to the call request after receiving the call request, which is used for indicating that the called terminal can carry out through communication with the calling terminal. The call mode information is identification information corresponding to different call modes according to specific call requirements when the calling terminal initiates a call after switching to the first through mode, and is used for the called terminal receiving the call request to make different reactions according to the different call mode information. Illustratively, in some embodiments, the call mode information includes a pass-through call information and a transit call information, respectively representing the establishment of a pass-through communication directly with the specified called terminal and the establishment of a transit communication by means of the specified called terminal. Furthermore, the transfer call information can be further divided into a first transfer information and a second transfer information, etc. so as to realize different transfer communication modes.

In some specific embodiments, after the calling terminal sends the activation frame for the designated times to the transfer station, if it is determined that the valid frame returned by the transfer station is not received, the calling terminal switches from the first transfer mode to the first pass-through mode, in the first pass-through mode, the second initial frequency point is used as a sending frequency point and also as a receiving frequency point, the calling terminal generates a call request in the first pass-through mode, and sends the generated call request to the called terminal. It should be noted that, in this embodiment, the failure of the calling terminal to initiate the transfer call to connect the transfer station may be the first call, or may be a reconnection attempt when the connection is disconnected after the first call is successful, which is not limited herein.

S120, after receiving confirmation information returned by the called terminal, the calling terminal establishes communication with the called terminal, wherein the confirmation information is generated after the called terminal switches to a first through mode according to a call request.

The confirmation information is used for determining that the called terminal can establish direct communication with the calling terminal, and is generated and sent after the called terminal is switched to a first direct communication mode according to a call request. In this embodiment, after the called terminal receives the call request, it switches to the first pass-through mode, and returns a confirmation message (usually ACK, acknowledge character, also called acknowledgement character) to the calling terminal, if the calling terminal can receive the confirmation message, it indicates that the called terminal and the calling terminal can establish the pass-through communication, otherwise, it indicates that the called terminal cannot receive the signal of the calling terminal, and it cannot successfully establish the pass-through communication. The through communication is a communication service (without the help of a relay station or other terminals) established directly between the calling terminal and the called terminal, at this time, the calling terminal is in a first through mode, the calling terminal can send signals by using the second initial frequency point as a sending frequency point, and receive signals by using the same frequency point (i.e. the receiving frequency point is the same as the sending frequency point), the called terminal can send and receive signals by using the second initial frequency point, at this time, the two signals are transmitted directly, i.e. the calling service is successfully established in the form of the through communication.

Optionally, in some embodiments, after the calling terminal and the called terminal complete the call service by means of the through communication, the calling terminal switches back to the first transit mode again, so as to enlarge the calling range of the calling terminal as much as possible while ensuring the success rate of the call (facilitating the transit communication again by means of the transit platform).

The embodiment provides a communication method applied to a calling terminal, when a transfer call connection transfer platform is initiated in a first transfer mode and fails, switching to the first through mode to send a call request to a called terminal, wherein the call request comprises call mode information of the calling terminal; and after receiving the confirmation information returned by the called terminal, the calling terminal establishes direct communication with the called terminal. According to the method, when the transfer platform can normally function, transfer communication between the calling terminal and the called terminal is established by means of the transfer platform, meanwhile, when the transfer platform is unavailable, the direct communication can be reestablished on the premise that the called terminal can receive the direct call, manual switching of a user is not needed, switching is smooth, non-inductive switching is achieved, user experience is improved, the direct communication is conducted on the premise that the called terminal can receive the direct communication, and channel resource waste caused by channel resource occupation when no actual call service exists is avoided.

Example two

Based on the first embodiment, the second embodiment of the present invention further explains and supplements part of the content in the first embodiment, for example, distinguishes the calling mode when the calling terminal performs individual calling and group calling, and specifically:

when the calling terminal makes a personal call (the transfer call initiated by the calling terminal is a personal call), that is, if there is only one called terminal, the calling terminal selects a personal call mode and determines the called terminal before sending a call request to the outside, the call mode information includes through call information, and the call request also includes identification information of the called terminal.

In the present switching schemes of the transit mode and the through mode (for example, the foregoing embodiment switches from the first transit mode to the first through mode), only the switching of the calling terminal is performed, that is, only the calling terminal is switched to the first through mode, and the called terminal still communicates in the first transit mode, so that only unidirectional signal transmission from the calling terminal to the called terminal can be realized, and the called terminal cannot call back. In this embodiment, when a call request is sent, the through call information of a designated communication mode is carried, and the called terminal switches to the first through mode according to the through call information, so that the called terminal can successfully establish a call service directly through the through call when calling back. It can be understood that, in fact, when the called terminal returns the acknowledgement information, it is already the signaling implemented after switching to the first through mode, and then during this service, the called terminal may maintain the first through mode to implement the call answering and callback with the calling terminal. Further, as in the calling terminal mentioned in the first embodiment, after the through call service is completed, the called terminal also automatically switches back to the first transfer mode, so as to expand the call range of the called terminal under the condition of ensuring the call success rate as much as possible.

When the calling terminal performs the group call (the transfer call initiated by the calling terminal is the group call), that is, if at least two called terminals exist, the calling terminal selects the group call mode before sending the call request outwards, the call mode information includes transfer call information, and the transfer call information is further divided into first transfer information and second transfer information, so as to implement different transfer calls.

When the call mode information comprises the first transfer information, the called terminal is switched to the first through mode to send the confirmation information, and then is switched to the first transfer mode according to the first transfer information.

Based on the technical limitation in the current communication field, the communication coverage of the communication terminal is far smaller than that of the transfer platform, so that during the group call, a part of called terminals often exceeds the communication coverage of the calling terminal and cannot establish a through call. At this time, after switching to the first pass-through mode and replying to the confirmation information, the called terminal also switches back to the first transfer mode to connect with the transfer station. And because the called terminal needs to be selected to be connected with the transfer platform, the selected called terminal needs to be ensured to be in the communication coverage range of the transfer platform, and therefore the confirmation information returned by the called terminal comprises first information used for indicating whether the corresponding called terminal is in the communication coverage range of the transfer platform.

In order to facilitate understanding of the group call scheme provided in this embodiment, as shown in fig. 2, another communication method applied to a calling terminal is further provided in some embodiments, where the method includes:

and S210, when the transfer call connection transfer platform is failed to be initiated in the first transfer mode, switching to a first through mode and sending a call request outwards, wherein the call request comprises call mode information, the first transfer mode takes a first initial frequency point as a sending frequency point and takes a second initial frequency point as a receiving frequency point, and the first through mode takes the second initial frequency point as the sending frequency point and the receiving frequency point.

Step S210 is the same as step S110 in the first embodiment, and will not be described here again.

S220, screening the called terminals in the communication coverage range of the relay station based on the first information to obtain a called terminal set.

As mentioned above, the purpose of selecting the called terminal in this embodiment is to complete the transfer communication between the calling terminal and other called terminals by means of the transfer platform connected with the called terminal, so that the selected called terminal is necessarily in the communication coverage area of the transfer platform, so that after receiving the confirmation information returned by the called terminal, it is first required to determine which called terminals are in the communication coverage area of the transfer platform (which means that the called terminal can receive the signal sent by the transfer platform and the transfer platform can also receive the signal sent by the called terminal), otherwise, the called terminal cannot implement the different-frequency transfer function from the calling terminal to the transfer platform, and a plurality of called terminals are usually screened out and collectively referred to as a called terminal set.

S230, determining the called terminal with the shortest reply interval in the called terminal set.

The reply interval refers to a time interval during which the calling terminal transmits a call request to the calling terminal to receive acknowledgement information. In this embodiment, since the call service initiated by the calling terminal needs to be transferred to the transfer station by a certain called terminal and then transferred to other called terminals, how to select a suitable called terminal from the plurality of called terminals for transfer is a primary problem. Considering that the transmission loss is larger when the distance is longer, the delay is generally higher in the signal transmission process, so that a called terminal closest to the calling terminal is preferably selected to perform the transfer between the calling terminal and the transfer platform, and the reply interval of the called terminal reflects the distance between the calling terminal and the called terminal (without considering the data processing speed of the called terminal), so that the called terminal with the shortest reply interval is preferably determined from the determined set of the called terminals according to the confirmation information, and the inter-frequency transfer is preferably performed.

S240, the called terminal is switched to a first transfer mode, and the calling terminal establishes communication with the called terminal with the shortest reply interval.

When the called terminal with the shortest reply interval is determined in the communication coverage area of the transfer platform, the calling terminal selects the called terminal (called as the different-frequency transfer terminal in the embodiment) to perform transfer communication to the transfer platform, namely the calling terminal directly initiates a through call to the called terminal with the shortest reply interval, and then the called terminal with the shortest reply interval transfers to the transfer platform in different frequencies, and the transfer platform transfers to other called terminals.

It should be understood that, in an alternative embodiment, steps S220-240 are not actually performed in the above order, for example, step S240 is performed first to select the called terminal with the shortest reply interval, then determine whether it is within the communication coverage of the relay station, if the called terminal with the shortest reply interval does not meet the condition of being within the communication coverage of the relay station, then remove the called terminal, reselect the called terminal with the shortest reply interval, and again determine whether the newly selected called terminal with the shortest reply interval meets the condition of being within the communication coverage of the relay station until finally selecting the called terminal that meets both the conditions of being within the communication coverage of the relay station and having the shortest reply interval as the inter-frequency relay station, and the calling terminal directly initiates the direct communication with the inter-frequency relay station.

Steps S220-240 are actually a detailed supplement to step S120, illustrating how the calling terminal selects the appropriate called terminal to establish the pass-through communication in the case of group calling.

In practical application, in order to avoid the problem of co-channel interference during the through communication, further, in some embodiments, the group call scheme is optimized, so that the calling terminal and the different-frequency transfer terminal jump to a first transformation frequency point different from the first initial frequency point and the second initial frequency point to make a call (that is, the calling terminal uses the first transformation frequency point as a transmitting frequency point and the different-frequency transfer terminal uses the first transformation frequency point as a receiving frequency point, and establishes communication between the calling terminal and the different-frequency transfer terminal through the first transformation frequency point), and then the different-frequency transfer terminal establishes communication with other called terminals by means of the transfer station to complete the group call.

Specifically, this embodiment is improved based on the previous embodiment, in this embodiment, if the transfer call is a group call, that is, there are at least two called terminals, the calling terminal selects a group call mode before sending a call request outwards, the call mode information includes second transfer information, the calling terminal switches to the second pass-through mode after sending the call request outwards, the second pass-through mode uses a first transformation frequency point as a sending frequency point and a receiving frequency point, the called terminal switches to the second transfer mode according to the second transfer information after switching to the first pass-through mode to send a confirmation information, the second transfer mode uses a first initial frequency point as a sending frequency point and uses a first transformation frequency point as a receiving frequency point, and the confirmation information further includes first information for indicating whether the corresponding called terminal is within a communication coverage area of the transfer station, where the communication method is shown in fig. 3, and includes:

and S210, when the transfer call connection transfer platform is failed to be initiated in the first transfer mode, switching to a first through mode and sending a call request outwards, wherein the call request comprises call mode information, the first transfer mode takes a first initial frequency point as a sending frequency point and takes a second initial frequency point as a receiving frequency point, and the first through mode takes the second initial frequency point as the sending frequency point and the receiving frequency point.

S250, screening the called terminals in the communication coverage range of the relay station based on the first information to obtain a called terminal set.

S260, determining the called terminal with the shortest reply interval in the called terminal set.

The actual principle of steps S250-260 is similar to steps S220-230, and the set of called terminals represents the called terminals within the communication coverage of the transfer station determined based on the first information (the acknowledgement information may also be different considering that the call request is different, and both actually refer to the called terminals that have replied to the acknowledgement information and are within the communication coverage of the transfer station).

S270, the calling terminal is switched to a second through mode, the called terminal is switched to a second transfer mode, and the calling terminal establishes communication with the called terminal with the shortest reply interval.

The main difference between step S270 and step S240 is that the calling terminal establishes a transmitting frequency point and a receiving frequency point when the direct communication is established between the calling terminal and the called terminal with the shortest reply interval: in step S240, the calling terminal switches to the first pass-through mode to send the call request, establishes pass-through communication in the first pass-through mode after receiving the acknowledgement information, and establishes pass-through communication with the second initial frequency point as the sending frequency point and the receiving frequency point, and in step S270, the calling terminal switches to the first pass-through mode to send the call request, then switches to the second pass-through mode, and establishes pass-through communication with the first conversion frequency point as the sending frequency point and the receiving frequency point after receiving the acknowledgement information. It will be understood, of course, that the second transfer information already makes the different frequency transfer end aware of the through call initiated by the first conversion frequency point as the receiving frequency point, so that the second transfer information can receive the through call initiated by the calling terminal using the first conversion frequency point as the sending frequency point, and further, after the second transfer mode is skipped, if the through call initiated by the first conversion frequency point is not received from the calling terminal (for example, if it is determined that the through call initiated by the first conversion frequency point is not received from the calling terminal within a preset period of time), the first transfer mode is automatically restored to receive the through call from the transfer end, that is, the second transfer information is also used to enable other called terminals to automatically restore the first transfer mode when the through call initiated by the first conversion frequency point is not received from the calling terminal.

The embodiment further provides another communication method applied to the calling terminal, when the calling terminal initiates a failure of a personal call in a first transfer mode, the communication method is switched to a first through mode, and the called terminal is switched to the first through mode to establish the through communication with the calling terminal, so that the calling terminal can receive the call and can return the call; when the calling terminal initiates the group call failure in the first transfer mode, a proper called terminal is selected to perform different-frequency transfer with a transfer station, then transfer communication with other called terminals is established through the transfer station, the called terminal in a wider range can be covered, the communication range of the calling terminal is expanded, signal transmission delay is reduced through a preset selection condition when the called terminal is selected to perform different-frequency transfer, call loss rate is reduced, and service reliability is improved.

Example III

A third embodiment of the present invention provides a communication method, which may be applied to a communication system including a communication terminal (e.g., a device such as a mobile phone) and a transverter, and may be implemented based on any of the foregoing embodiments of the present invention, where the embodiment is described by taking the application of the method to a called terminal in the communication terminal as an example, and specifically, as shown in fig. 4, the method includes the following steps:

S310, switching to a first through mode according to a received call request, wherein the call request is generated and sent by a calling terminal when a transfer call connection transfer platform is failed in a first transfer mode, the call request comprises call mode information, the first transfer mode takes a first initial frequency point as a sending frequency point and a second initial frequency point as a receiving frequency point, and the first through mode takes the second initial frequency point as the sending frequency point and the receiving frequency point.

The initial communication mode of the called terminal is a first transfer mode, and in the first transfer mode, the called terminal uses a first initial frequency point as a sending frequency point to send signals and uses a second initial frequency point as a receiving frequency point to receive signals. When a user initiates a transfer call to a called terminal through a transfer platform by using a calling terminal, if the connection of the calling terminal to the transfer platform fails, the calling terminal is switched to a first on mode, a call request is generated and is sent by taking a second initial frequency point as a sending frequency point, the called terminal enters the first on mode after receiving the call request through a second video point, and in the first on mode, the called terminal sends a signal by the second initial frequency point and receives the signal by the second initial frequency point (namely, the same frequency point is adopted for actual sending and receiving).

S320, sending confirmation information to the calling terminal according to the call mode information and establishing communication with the calling terminal.

After entering the first pass-through mode, the called terminal generates confirmation information for confirming that the call request is received, and sends the confirmation information to the calling terminal through the second initial frequency point.

After receiving the confirmation information returned by the called terminal, the calling terminal directly initiates a call to the called terminal in a first direct mode, and the called terminal receives the call of the calling terminal in the first direct mode to establish direct communication between the calling terminal and the called terminal so as to complete call service.

Optionally, in some embodiments, the called terminal automatically switches back to the first transfer mode after the call service is finished, so as to enlarge the call range of the communication terminal (the called terminal may also be used as the calling terminal to perform the next communication) under the condition of ensuring the call success rate as much as possible.

The embodiment provides a communication method applied to a called terminal, the called terminal is switched to a first through mode after receiving a call request sent by a calling terminal and sends confirmation information to the calling terminal, so that the calling terminal establishes through communication with the called terminal according to the confirmation information.

Example IV

The fourth embodiment of the present invention further provides another communication method applied to the called terminal on the basis of the third embodiment, which further explains and supplements a part of the content in the third embodiment, and is mainly different in that a transfer call process by means of a transfer table when the calling terminal performs group call is supplemented, and the communication method provided in the present embodiment includes two schemes:

in a first aspect, the call request includes first transfer information, and after the called terminal switches to the first through mode to send acknowledgement information, the called terminal switches back to the first through mode according to the first transfer information, switches to the first through mode according to the received call request, and sends acknowledgement information to the calling terminal, the method further includes: and switching to a first transfer mode according to the first transfer information, establishing communication with the transfer station, and establishing communication with other called terminals through the transfer station. The specific communication process includes, as shown in fig. 5:

s410, switching to a first through mode according to a received call request, wherein the call request is generated and sent by a calling terminal when a transfer call connection transfer platform is failed in a first transfer mode, the call request comprises call mode information, the first transfer mode takes a first initial frequency point as a sending frequency point and a second initial frequency point as a receiving frequency point, and the first through mode takes the second initial frequency point as the sending frequency point and the receiving frequency point.

S420, sending confirmation information to the calling terminal according to the call mode information.

The principle of the steps S410-420 is the same as that of the steps S310-320 in the third embodiment, and will not be repeated here.

S430, switching to a first transfer mode according to the first transfer information, establishing communication with the calling terminal, establishing communication with the transfer station, and establishing communication with other called terminals through the transfer station.

In a second scheme, the call request includes second transfer information, the called terminal switches to the first pass mode to send acknowledgement information, and then switches to the second transfer mode according to the second transfer information, that is, switches the sending frequency point to the first initial frequency point, and switches the receiving frequency point to the first conversion frequency point, as shown in fig. 6, and the specific process includes:

s410, switching to a first through mode according to a received call request, wherein the call request is generated and sent by a calling terminal when a transfer call connection transfer platform is failed in a first transfer mode, the call request comprises call mode information, the first transfer mode takes a first initial frequency point as a sending frequency point and a second initial frequency point as a receiving frequency point, and the first through mode takes the second initial frequency point as the sending frequency point and the receiving frequency point.

S420, sending confirmation information to the calling terminal according to the call mode information.

The principle of the steps S410-420 is the same as that of the steps S310-320 in the third embodiment, and will not be repeated here.

S440, switching to a second transfer mode according to the second transfer information of the frequency point information, establishing communication with the calling terminal, establishing communication with the transfer station, and establishing communication with other called terminals through the transfer station.

Specifically, in two schemes for establishing a transit call by means of a called terminal: the first is that the calling terminal is switched to a first through mode, and the called terminal is switched back to a first transfer mode for transfer after being switched to the first through mode, namely, the called terminal is switched back to the first transfer mode and establishes transfer communication with other called terminals through a transfer platform; the second method is that the called terminal and the calling terminal jump to the first conversion frequency point to communicate at the same time, namely the calling terminal switches the sending frequency point to the first conversion frequency point, meanwhile the called terminal switches the receiving frequency point to the first conversion frequency point, and the sending frequency point is recovered to be the first initial frequency point (same as the receiving frequency point of the intermediate turntable), and intermediate communication with other called terminals is established through the intermediate turntable.

For the first scheme, the communication terminal switches from the first through mode to the first transfer mode, in this embodiment, considering that the communication coverage of the calling terminal is smaller, when there are multiple called terminals, it is difficult to cover all the called terminals, so that the calling terminal selects one of the multiple called terminals to perform inter-frequency transfer, at this time, after the called terminal switches to the first through mode, the called terminal forwards a signal from the calling terminal to the transfer station, so as to implement inter-frequency transfer between the calling terminal and the transfer station, and finally the transfer station forwards the signal to other called terminals, so as to implement communication (including through communication and transfer communication) from the calling terminal to all the called terminals.

For the second scheme, the called terminal and the calling terminal jump to the first conversion frequency point to make a through call at the same time, at the moment, the calling terminal uses the first conversion frequency point as a transmitting frequency point in the second through mode, and the called terminal uses the first conversion frequency point as a receiving frequency point in the second transfer mode to establish the through communication, and the called terminal also uses the first initial frequency point as the transmitting frequency point in the second transfer mode, at the moment, the called terminal cannot call back, but the called terminal forwards signals from the calling terminal to the transfer station to realize different frequency transfer between the calling terminal and the transfer station, and finally the transfer station forwards the signals to other called terminals to realize communication from the calling terminal to all the called terminals. Of course, in this scheme, after the receiving frequency point is switched to the first conversion frequency point, if the other called terminal fails to receive the through call initiated by the calling terminal with the first conversion frequency point, it needs to switch back to the first conversion mode, and the second initial frequency point is used as the receiving frequency point to receive the signal from the relay station.

It should be noted that, step S430 and step S440 illustrate steps performed by the called terminal selected to perform the inter-frequency transfer, for other called terminals not selected to perform the inter-frequency transfer, the other called terminals may switch back to the first transfer mode after replying to the confirmation information, and after the call service is completed, all the called terminals need to switch back to the first transfer mode, so as to expand the call range of the communication terminal (the called terminal may also be used as the calling terminal to make the next call) under the condition of ensuring the call success rate as much as possible.

The embodiment provides a communication method applied to a called terminal, when a calling terminal initiates a group call failure by a transfer call, a proper called terminal is selected to perform different-frequency transfer with a transfer station, and then transfer communication with other called terminals is established through the transfer station, so that the communication range of the calling terminal is expanded, the reliability of a service is improved, different transfer communication schemes are provided, the problem of same-frequency interference can be solved, and the requirement on the hardware condition of the called terminal is reduced.
