Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating an embodiment of a method for increasing a communication distance, where the method is applied to a wideband/narrowband convergence system, and the method includes:
step 11: and the calling terminal sends a service request to the calling transfer terminal.
The broadband and narrowband fusion system comprises a plurality of terminals, wherein a calling transfer terminal is a terminal with a transfer function and can receive and transfer a service request, and a calling terminal is a terminal working in a DMO mode and can send or receive the service request; specifically, the calling terminal is a terminal initiating a service request, and the calling relay terminal is a terminal located in the same network as the calling terminal; the calling transfer terminal and the called transfer terminal can be multimode terminals, namely can work in a broadband mode and can also work in a narrow-band mode.
Further, the broadband and narrowband convergence system may include a plurality of independent networks, each independent network includes a plurality of terminals, the operating frequency of each independent network may be different, one terminal having a forwarding function in each independent network may be provided, and the number of terminals receiving or initiating a service request may be provided as multiple terminals, for example, as shown in fig. 2, the broadband and narrowband convergence system includes a broadband base station 21 and a plurality of independent networks LA1-LAn, the independent network LA1 includes a terminal MS1 and a terminal MS2, the independent network LA2 includes a terminal MS3 and a terminal MS4, the independent network LAn includes a terminal MSn and a terminal MSn +1, each independent network configures the same narrowband group and broadband group, that is, each independent network is in the same narrowband group and broadband group, for example, the calling terminal is a terminal MS2 in the independent network LA1, the called terminal is to communicate with the terminal MS4 in the broadband and the called terminal MS4 in the broadband group, the calling terminal MS2 holds a service request to the terminal MS1 in the same independent network LA1, the calling terminal MS2 is a terminal MS1, the calling terminal MS2 is connected to the terminal MS4 in the broadband and the called terminal MS4, and the called terminal MS is capable of establishing a call through the call, and the called terminal MS is capable of establishing a call with the called terminal MS4, and then the called terminal MS, and the called terminal MS is capable of establishing a call.
It can be understood that the calling terminal may also perform group calling on all terminals in the narrowband group, and forward the service request through the calling relay terminal, the broadband base station, and the called relay terminal, so as to establish service connection with all terminals in the narrowband group.
Step 12: the calling transfer terminal sends the service request to the broadband base station, so that the broadband base station forwards the service request to the corresponding called transfer terminal.
The calling transfer terminal sends the received service request to the broadband base station, and then the broadband base station forwards the service request to a corresponding called transfer terminal, wherein the called transfer terminal is a terminal which is positioned in the same independent network with the called terminal. Specifically, the calling relay terminal in the broadband-narrowband convergence system can relay the received signal, and after receiving the service request sent by the calling terminal, the calling relay terminal can forward the service request to the broadband base station, so that the service request of the calling terminal can be forwarded to the called relay terminal through the broadband base station.
Continuing to take the example of the wideband-narrowband convergence system in fig. 2 as an example, the calling relay terminal MS1 sends the received service request to the wideband base station 21, and since the calling terminal MS2 needs to establish communication with the called terminal MS4, the wideband base station 21 forwards the service request to the called relay terminal MS3 after receiving the service request, so that the called relay terminal MS3 forwards the service request in the independent network LA2 corresponding to the called relay terminal MS 3.
Step 13: the called transfer terminal forwards the service request to the called terminal so as to establish service connection between the calling terminal and the called terminal.
After receiving the service request, the called relay terminal forwards the service request to the called terminal, so as to establish a service connection between the calling terminal and the called terminal, for example, the called relay terminal MS3 in fig. 2 forwards the received service request to the called terminal MS4, so as to establish a service connection between the calling terminal MS2 and the called terminal MS 4.
The embodiment provides a method for improving communication distance, a calling terminal firstly sends a service request to a calling transfer terminal, the calling transfer terminal forwards the service request to a broadband base station after receiving the service request, so that the broadband base station forwards the service request to a called transfer terminal in the same independent network with the called terminal, and the called transfer terminal forwards the received service request to the called terminal, so as to establish service connection between the calling terminal and the called terminal; the terminal initiating the call can transfer the service request through the terminal in the same network and transmit the service request to the called terminal through the broadband base station, the communication distance between the calling terminal and the called terminal can be increased through setting the transfer terminal, and meanwhile, the transfer terminal transmits the service request to the broadband base station and can transmit the service request to terminals in other independent networks with different working frequencies through the broadband system, so that the communication between the terminals with cross frequency points is realized.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating another embodiment of a method for increasing a communication distance according to the present application, where the method is applied to a narrowband convergence system, where the narrowband convergence system includes multiple terminals, and the method includes:
step 31: the terminal broadcasts presence information.
In order to construct communication connection between terminals in each independent network in the broadband and narrowband convergence system, one terminal in each independent network broadcasts presence information, so that other terminals in the same network with the terminal can receive the presence information to establish communication connection between the terminals in the independent network.
It can be understood that each terminal in the wideband-narrowband convergence system is configured with the same wideband group and wideband group, and the operating frequency of each independent network may be different, and a terminal having the same operating frequency as the terminal broadcasting the presence information may receive the presence information broadcasted by the terminal.
Step 32: the terminal that receives the presence information establishes a communication connection with the terminal that transmitted the presence information.
After receiving the presence information broadcast by one of the terminals, the other terminal receiving the presence information establishes a communication connection with the terminal sending the presence information according to the presence information, specifically, the presence information may include address information of the terminal sending the presence information, and the other terminal may connect with the terminal according to the address information, thereby establishing a communication connection between the terminals in the independent network.
It is understood that there may be multiple independent networks in the wideband and narrowband converged system, and there may also be multiple terminals in each independent network, and other terminals with the same operating frequency as the terminal broadcasting the presence information may receive the presence information. For example, taking the wideband-narrowband convergence system shown in fig. 2 as an example, the system includes two independent networks: an independent network LA1 and an independent network LA2, a terminal MS2 in the independent network LA1 receives the existence information broadcast by a terminal MS1 and establishes contact with the existence information, and a terminal MS4 in the independent network LA2 receives the existence information broadcast by a terminal MS3 and establishes contact with the existence information.
Step 33: and the calling terminal sends the service request to a narrowband module in the calling relay terminal.
The calling terminal sends the service request to a narrowband module in the calling relay terminal, so that the narrowband module forwards the service request to a broadband module in the calling relay terminal; specifically, the calling relay terminal includes a narrowband module and a broadband module, i.e., a multimode terminal, which are connected to each other, where a working mode of the narrowband module may be a relay mode, and a working mode of the broadband module may be a broadband trunking mode; a calling terminal in the wideband and narrowband convergence system is a terminal working in a DMO mode to send or receive a service request, and further, the terminal may also be a narrowband terminal, that is, a terminal only working in the narrowband system, or a multimode terminal with a narrowband module working in the DMO mode, that is, the terminal does not have a relay function and only sends or receives a service request, in a specific embodiment, the type of the calling terminal may include but is not limited to a narrowband terminal and a multimode terminal; it is to be understood that the type of the called terminal or the terminal without a relay function in each independent network is the same as the type setting of the calling terminal, and the type of the called relay terminal or the terminal with a relay function in each independent network is the same as the type setting of the calling relay terminal.
For example, taking the wideband-narrowband convergence system shown in fig. 4 as an example, the narrowband module in the terminal operating in the relay mode is represented by Repeater, and the wideband module operating in the wideband cluster mode is represented by BB, where the wideband-narrowband convergence system includes four independent networks LA1 to LA4, a calling terminal is a terminal MS2, a called terminal is a terminal MS6, and the calling terminal MS2 sends a service request to the Repeater 421 in the calling relay terminal MS1, so that the Repeater 421 forwards the service request to the BB 422 in the calling relay terminal MS 1.
Step 34: and the broadband module sends the service request to a broadband base station.
After receiving the service request, the broadband module of the calling relay terminal sends the service request to the broadband base station, so that the service request can be transmitted to the independent network where the called terminal is located through the broadband system. As shown in fig. 4, repeater 421 receives a service request sent by calling terminal MS2, and forwards the service request to BB 422, and then BB 422 sends the service request to broadband base station 41, so that the service request sent by the calling terminal operating in DMO mode can be transmitted to other independent networks through the broadband system.
Step 35: the broadband base station sends the service request to a broadband module in the called transfer terminal.
Configuring the same narrow-band system and the same broadband system in the wide-band and narrow-band converged network, namely that the terminals in the wide-band and narrow-band converged network all belong to the same narrow-band group, and the broadband modules in the terminals all belong to the same broadband group; for example, as shown in fig. 4, the narrowband group G1 (not shown) includes MS2, MS4, MS6, and MS8, and the wideband group G2 (not shown) includes MS1, MS3, MS5, and MS7; it is understood that the narrowband module of the terminal operating in the relay mode may also configure a narrowband group different from G1, for example, the narrowband group G3, which is capable of receiving and forwarding the service request of the calling terminal in the narrowband group G3 to the narrowband group G1 in the narrowband convergence system, so as to establish a communication connection between different narrowband systems.
After receiving the service request forwarded by the calling multimode terminal, the broadband base station sends the service request to the broadband modules of all terminals with a relay function in the broadband group in the broadband-narrowband convergence system, that is, sends the service request to the broadband modules of all terminals with a relay function in all independent networks.
And step 36: and the broadband module in the called transfer terminal analyzes the service request to obtain service information.
The service request sent by the calling terminal may include service information, and the broadband module of the called relay terminal parses the service request after receiving the service request, so as to obtain the service information, where the service information may include a service type, an address of the calling terminal, and a destination address.
Further, the calling terminal may initiate a call service or a group call service, that is, it may make a single call to a certain called terminal, or may initiate a combined call to all called terminals in the narrowband group, that is, a destination address included in the service information may be an address of a certain terminal and a group address of a narrowband group.
When the calling terminal performs an individual call service, the service request sent by the calling terminal includes the address of the called terminal, as shown in fig. 4, the calling terminal MS2 initiates an individual call service to the terminal MS6 in advance, the service request carries the address of the terminal MS6, after receiving the service request forwarded by the calling relay terminal MS1, the broadband base station 41 sends the service request to all terminals with relay function in the broadband group G2 through the broadband system, that is, the terminal in which the narrowband module operates in the relay mode, sends the service request to the BB 432 of the terminal MS3, the BB 442 of the terminal MS5, and the BB 452 of the terminal MS7, and then the terminals MS3, MS5, and MS7 re-identify the address of the called terminal MS6 in the service request, so as to establish the individual call service between the calling terminal MS2 and the called terminal MS 6.
Similarly, when the calling terminal performs a group call service, a service request sent by the calling terminal includes a group address of a called narrowband group, as shown in fig. 5, the calling terminal MS2 initiates a group call service to all terminals operating in a DMO mode in the narrowband group G1 in advance, and the service request carries the group address of the narrowband group G1; specifically, the calling terminal MS2 sends the group call service to all the called terminals (i.e. the called terminals MS4, MS6, and MS 8) in the narrowband group G1 in advance, the broadband base station 41 also sends the service request to the BB 432 of the called relay terminal MS3, the BB 442 of the called relay terminal MS5, and the BB 452 of the MS7 in the narrowband group G2 after receiving the service request sent by the calling relay terminal MS1, and then the called relay terminals MS3, MS5, and MS7 identify the group address of the narrowband group G1 in the service request, thereby establishing the group call service between the calling terminal MS2 and the called terminals MS4, MS6, and MS8 in the narrowband group G1.
In a specific embodiment, the service type of the calling terminal may include a voice service and a short message service, and when the calling terminal initiates the short message service, the service request sent by the calling terminal includes the service type, the address of the calling terminal, and the destination address of the called terminal.
When the calling terminal initiates a voice service, the service request sent by the calling terminal only comprises the service type and the destination address, and the service request sent by the calling terminal does not carry the address of the calling terminal at the moment, so that the data volume carried by the service request is reduced, and the transmission efficiency is improved; in addition, in order to enable the called terminal to acquire the address of the calling terminal so as to display the address of the calling terminal during voice communication and perform the speaking right switching operation during voice communication with the calling terminal, the calling terminal can transmit the address of the calling terminal to the called terminal through data frames with preset number at intervals after establishing service connection, so that the called terminal acquires the address of the calling terminal, and understandably, the preset number can be set according to actual conditions.
In a specific embodiment, the calling terminal may carry its own address in a data packet sent to the called terminal, where the data packet may include 18 data frames, the first 1 to 17 data frames may carry content information of a voice call, and the 18 th data frame may carry other information, and at this time, the calling terminal may carry its own address in the 18 th data frame of each data packet, that is, the calling terminal sends the address of the calling terminal to the called terminal at intervals of 18 data frames, so that the called terminal can know the address of the calling terminal. In other embodiments, the calling terminal may further send its own address to the called terminal in the form of frame stealing, that is, the calling terminal may further arbitrarily select a half data frame from the first 1-17 data frames of the data packet to carry the address of the calling terminal, for example, the address of the calling terminal may be carried in the first half frame of the 11 th data frame, and then the address is sent to the called terminal.
Step 37: the broadband module sends the service information to a narrowband module in the called transfer terminal.
After the broadband module of the called transfer terminal analyzes the service information, the analyzed service information is sent to the narrowband module of the called transfer terminal, so that the narrowband module of the called transfer terminal judges the service information, and judges whether to forward the service request according to a destination address contained in the service information, namely whether to establish service connection between the terminal under the network to which the terminal belongs and the calling terminal. Specifically, when the destination address is a single terminal, that is, when the calling terminal initiates a call service, the narrowband module of the terminal that receives the service request judges the destination address, and judges whether the called terminal corresponding to the destination address belongs to the independent network where the terminal is located, and if the called terminal is in the same independent network as the called terminal, the narrowband module forwards the service request to the called terminal; if the called terminal is not in the independent network where the terminal is located, the narrowband module does not forward the service request. It can be understood that, when the calling terminal initiates a group call service, the destination address is a group address of a narrowband group, and all narrowband modules forward the service information.
Step 38: and when the working mode of the narrow-band module is the relay mode, the narrow-band module initiates a service request corresponding to the service information so as to establish service connection between the calling terminal and the called terminal.
When the called terminal corresponding to the destination address contained in the service information is in the independent network where the terminal is located, or when the destination address is a narrowband group address, if the narrowband module in the terminal receiving the service request works in a relay mode, that is, the terminal is a called relay terminal with relay capability, the narrowband module sends the service request to the called terminal corresponding to the destination address.
It can be understood that, if the narrowband module of the terminal that receives the service request does not operate in the relay mode, for example, the narrowband module operates in the DMO mode, the terminal does not have a relay function, and at this time, the narrowband module in the terminal does not forward the service request after analyzing the service information.
Please refer to fig. 6, fig. 6 is an interaction schematic diagram between a calling terminal, a calling relay terminal, a broadband base station, a called relay terminal, and a called terminal provided in the present application, where the calling terminal sends a service request to a narrowband module of the calling relay terminal, then the narrowband module of the calling relay terminal working in a relay mode forwards the service request to its own broadband module, and then the broadband module sends the service request to the broadband base station, so that the broadband base station sends the service request to the broadband modules of all relay terminals in the broadband-narrowband fusion system through the broadband system, then the broadband module of each relay terminal analyzes the service request, and forwards the analyzed service information to its own narrowband module, and then the narrowband module sends the service request to the corresponding called terminal based on a destination address in the service information, thereby establishing a service connection between the calling terminal and the called terminal.
The broadband and narrowband convergence system provided by the embodiment comprises a plurality of independent networks, a calling terminal in each independent network can forward a service request to a called relay terminal in other independent networks through the calling relay terminal connected with the calling terminal, and then forward the service request to a corresponding called terminal again through the called relay terminals in other independent networks, so that service connection among terminals in different independent networks is established, a group call service or an individual call service initiated by the calling terminal is completed, multi-hop of communication signals among the terminals can be realized, the communication distance among the terminals is further improved, and the broadband and narrowband convergence system can be applied to scenes with higher requirements on the communication distance.
