Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
Fig. 1 is a flowchart of a first communication method provided in an embodiment of the present invention, and as shown in fig. 1, the method is applied to a first mobile terminal, and may include:
In the embodiment of the present invention, the first mobile terminal, the second mobile terminal, and the third mobile terminal may be mobile terminals joining a 5G network, or may be mobile terminals joining an end-to-end communication system. Because the 5G technology and the peer-to-peer communication system adopt peer-to-peer communication, the mobile terminal itself can be used as a relay service device for information to receive or forward information of a base station or other mobile terminals. For convenience of description, the embodiment of the present invention takes a mobile terminal that joins a 5G network as an example, but it should be noted that the embodiment of the present invention is not limited to be applied to a 5G network, and all networks or systems that can implement the embodiment of the present invention belong to the scope that needs to be protected by the embodiment of the present invention.
When the first mobile terminal uses the communication network, the nearest base station can be intelligently selected to be connected for communication. As the position of the first mobile terminal changes, the base station to which it is connected also changes. Due to geographical environment and the like, when the first mobile terminal moves, some areas where the base station signal cannot cover or areas where the signal is weak may be entered.
The condition that the first signal strength is smaller than the first strength threshold and larger than the second strength threshold means that the signal strength of the first mobile terminal is weak but the first mobile terminal can support communication with the base station, and the condition that the first signal strength is smaller than the second strength threshold means that the connection signal between the first mobile terminal and the base station is very weak and communication between the first mobile terminal and the base station cannot be supported, which is equivalent to the condition that the first mobile terminal is disconnected from the base station. The specific values of the first intensity threshold and the second intensity threshold can be preset according to actual conditions.
In a case where the strength of the first signal received from the base station is less than the first strength threshold and greater than the second strength threshold, at this time, the first mobile terminal may detect a second mobile terminal having a communication relay service function in a neighborhood by using a corresponding application program.
And step 102, selecting a first target transfer terminal from the second mobile terminal according to the second signal strength received by the second mobile terminal from the base station and the distance between the second mobile terminal and the first mobile terminal.
In the embodiment of the present invention, when the first mobile terminal detects that a second mobile terminal having a communication relay function exists in the vicinity of the first mobile terminal, the second signal strength received by the second mobile terminal from the base station and the distance between the second mobile terminal and the first mobile terminal may be obtained. Specifically, the information of the second signal strength and the distance corresponding to the second mobile terminal may be selectively obtained by a request of the user in the application program, or the information list of the second signal strength and the distance may be directly displayed on the application program interface when the second mobile terminal is detected.
When the second signal strength and the distance can support the second mobile terminal to become a communication transfer terminal, the first mobile terminal determines the second mobile terminal as a target transfer terminal; when there are multiple second mobile terminals, the first mobile terminal may select an optimal target transfer terminal from the second mobile terminals according to the second signal strength and the distance.
The second mobile terminal is in a 5G running state, so that the power consumption loss is small when the second mobile terminal is used as a transfer terminal; however, the second mobile terminal may also determine whether to start the transit service currently according to its remaining power and the expected usage. If the mobile terminal does not start the transfer service, the mobile terminal cannot be used as the target transfer terminal, and the first mobile terminal cannot select the mobile terminal as the target transfer terminal.
In addition, if the second mobile terminal is in the power-off state, it cannot be used as the target relay terminal.
Preferably, the selecting a first target transfer terminal from the second mobile terminal according to the second signal strength received by the second mobile terminal from the base station and the distance between the second mobile terminal and the first mobile terminal includes:
for each second mobile terminal, weighting and summing a second signal strength of the second mobile terminal and a distance between the second mobile terminal and the first mobile terminal by adopting a preset weight to obtain a candidate score of the second mobile terminal;
and selecting the second mobile terminal with the highest candidate score as the target transit terminal.
In the embodiment of the present invention, weights of the second signal strength and the distance may be preset, then the preset weights are used to perform weighted summation on the obtained second signal strength and the distance of each second mobile terminal, so as to obtain candidate scores, and the second mobile terminal with the highest candidate score is selected as the target transit terminal.
And a mode of weighting and summing to obtain candidate scores is adopted, so that the performance of each second mobile terminal as a transit terminal can be better measured, and the performance of the whole relay information of the second mobile terminal with the highest candidate score is better. By adopting the scheme, the first mobile terminal can be helped to select a more appropriate target transfer terminal.
In the embodiment of the invention, when the strength of the first signal received by the first mobile terminal from the base station is less than the second strength threshold value, the first mobile terminal and the base station are disconnected. At this time, if the first mobile terminal wants to obtain the relay service, the first mobile terminal needs to let the neighboring relay terminals know the communication relay requirement of the first mobile terminal.
At this time, the first mobile terminal may send the communication relay request to the neighborhood in the form of a broadcast message. The coverage of the broadcast message is limited, for example within a distance of 1 km centred on the first mobile terminal. If a third mobile terminal exists within the range, the third mobile terminal may receive the broadcast message. The broadcast message includes the device identification information of the first mobile terminal, the communication relay request information, the first signal strength and other information, and the third mobile terminal sends the response information to the first mobile terminal according to the information. For example, the response message may include information such as a third signal strength of the third mobile terminal, a distance between the third mobile terminal and the first mobile terminal.
When the third signal strength and the distance can support the third mobile terminal to become a transfer terminal, the first mobile terminal determines the third mobile terminal as a target transfer terminal; when there are multiple third mobile terminals, the first mobile terminal may select an optimal target transfer terminal from the third mobile terminals according to the third signal strength and the distance.
And 104, establishing communication with the base station through the first target relay terminal under the condition that the strength of the first signal received from the base station is smaller than a first strength threshold and larger than a second strength threshold.
In the embodiment of the invention, after the first mobile terminal selects the first target transfer terminal, when the first mobile terminal is disconnected from the base station, the first mobile terminal automatically relays the base station resource data from the first target transfer terminal, so that the base station establishes communication with the base station, and the network continuity of the first mobile terminal in an area with weak network signal intensity is ensured.
And 105, establishing communication with the base station through the second target relay terminal under the condition that the strength of the first signal received from the base station is smaller than a second strength threshold value.
In the embodiment of the invention, after the first mobile terminal selects the second target transfer terminal, when the first mobile terminal is disconnected from the base station, the first mobile terminal automatically relays the base station resource data from the second target transfer terminal, so that the base station establishes communication with the base station, and the network continuity of the first mobile terminal in a network-free area is ensured.
Preferably, the establishing communication with the base station through the first target relay terminal includes:
receiving information sent by the base station through the first target transit terminal, and/or sending information to the base station through the first target transit terminal;
the establishing communication with the base station through the second target transfer terminal includes:
and receiving the information sent by the base station through the second target transfer terminal, and/or sending the information to the base station through the second target transfer terminal.
In the embodiment of the invention, the first mobile terminal and the base station can normally receive and send information through the relay of the target relay terminal.
Specifically, the first target relay terminal receives signals of base stations and forwards a part of the signals of the base stations to the first mobile terminal; and/or the first target transfer terminal receives the signal of the first mobile terminal and transfers the signal to the base station.
The second target transfer terminal receives the signals of the base stations and transfers a part of the signals of the base stations to the first mobile terminal; and/or the second target transfer terminal receives the signal of the first mobile terminal and transfers the signal to the base station.
Further, in consideration of the power problem of the target relay terminal, the base station may allocate part of the resources as needed, so as to provide more communication resource data for the target relay terminal.
Preferably, when the strength of the first signal received by the first mobile terminal from the base station is greater than a first strength threshold, the connection with the first target relaying terminal or the connection with the second target relaying terminal is disconnected.
And under the condition that the first signal strength is greater than the first strength threshold value, the first mobile terminal does not need the transfer service any more, and the first mobile terminal disconnects from the target transfer terminal and directly communicates with the base station.
In the embodiment of the present invention, a first mobile terminal detects a second mobile terminal having a communication relay service function when a first signal strength is smaller than a first strength threshold and larger than a second strength threshold; selecting a first target transfer terminal from the second mobile terminal according to the strength of a second signal received by the second mobile terminal from a base station and the distance between the second mobile terminal and the first mobile terminal; and under the condition that the first signal intensity is smaller than a second intensity threshold value, sending a broadcast message requesting communication transfer, receiving a response message returned by a third mobile terminal according to the broadcast message, and determining a second target transfer terminal from the third mobile terminal according to the response message. Therefore, when the first mobile terminal is disconnected from the base station, the base station resource data can be relayed from the first target relay terminal or the second target relay terminal, and the network continuity of the first mobile terminal is ensured.
Fig. 2 is a flowchart of a second communication method provided in an embodiment of the present invention, and as shown in fig. 2, the method is applied to a base station, and the method may include:
In the moving process of the first mobile terminal, the 5G base station (hereinafter referred to as base station) acquires the received signal strength information of the first mobile terminal in real time. When the first mobile terminal moves, some areas where signals cannot be covered or areas where signals are weak may be entered due to geographical circumstances and the like. When the strength of a first signal received by the first mobile terminal from the base station is smaller than a first strength threshold value and larger than a second strength threshold value, the base station acquires information of a second mobile terminal which is near the first mobile terminal and can be used as a transfer terminal from a target database.
In addition, under the condition that the received signal strength of the first mobile terminal is greater than the first strength threshold, the base station may also pre-determine the received signal strength of the first mobile terminal within a preset time according to the movement trend of the first mobile terminal and the network characteristics of the area where the first mobile terminal is located. For example, whether the first mobile terminal is about to enter a geographic no-network area is determined by acquiring a GPS navigation destination set by the first mobile terminal in a third-party application.
When the base station prejudges that the received signal strength of the first mobile terminal in the preset time is smaller than the first strength threshold value, the base station acquires a second mobile terminal which starts the communication transfer service function currently from the target database.
And the target database comprises all mobile terminals which are registered in the target area for the 5G network and are willing to be communication transfer terminals. The base station can sign a communication transfer service agreement according to the intention of a user when the mobile terminal initially joins in the 5G network, the mobile terminal joining in the communication transfer service agreement is collected into the target database, and the mobile terminal in the target database is endowed with the function of the communication transfer terminal. Specifically, the communication relay terminal may provide the communication relay service for the other mobile terminal, and may also enjoy the communication relay service of the other mobile terminal.
According to the uplink and download speeds of the base station resource acquired by the second mobile terminal, the base station determines the strength of a second signal received by the second mobile terminal from the base station; according to the positioning information of the first mobile terminal and the second mobile terminal, the base station acquires the distance between the second mobile terminal and the first mobile terminal.
And the base station judges whether the second mobile terminal is suitable to be used as a transfer terminal according to the second signal strength, and if the received signal strength of the second mobile terminal is very weak, the capability of transferring information is not enough to support the second mobile terminal to be used as a transfer terminal. Meanwhile, the base station also needs to judge whether the distance between the second mobile terminal and the first mobile terminal meets the requirement, and if the distance is too far, the second mobile terminal is not suitable to be used as a transfer terminal. And when the second signal strength and the distance between the second mobile terminal and the first mobile terminal meet the requirements, the base station determines the second mobile terminal as a target transfer terminal.
The base station selects the second mobile terminal as the transfer terminal without authentication of the transfer terminal, and the receiving resource belongs to base station distribution regulation, so that any personal information of the transfer terminal is not acquired, and only the transfer terminal is required to be in a running state.
When the base station detects that a plurality of second mobile terminals which start the relay service are arranged near the first mobile terminal, the base station selects an optimal relay terminal from the plurality of second mobile terminals as a target relay terminal according to the second signal strength received by each second mobile terminal and the distance between each second mobile terminal and the first mobile terminal.
In the embodiment of the invention, after the base station selects the target transfer terminal, the target transfer terminal is connected with the first mobile terminal in a default mode, and when the first mobile terminal is disconnected from the base station, the base station resource data is automatically relayed from the target transfer terminal, so that the base station and the first mobile terminal establish communication, and the service continuity of the mobile terminal in a special area is ensured.
It should be noted that, in the embodiment of the present invention, a plurality of second mobile terminals located in a vicinity of the first mobile terminal may be respectively connected to different base stations, at this time, the total base station may respectively obtain the second signal strength received by each second mobile terminal and the distance between each second mobile terminal and the first mobile terminal, use a preset weight to perform weighted summation on the second signal strength of the second mobile terminal and the distance between the second mobile terminal and the first mobile terminal, obtain a candidate score of the second mobile terminal, and select the second mobile terminal with the highest candidate score as the target transit terminal.
Fig. 3 shows a schematic diagram of a communication method comprising a plurality of base stations. In fig. 3, A, B, C are three different base stations, respectively, where mobile terminal B is currently connected to base station B, mobile terminal C is currently connected to base station C, and mobile terminal a is in a non-network area. At this time, the total base station may obtain the second signal strength received by the mobile terminal B from the base station B, the distance between the mobile terminal B and the mobile terminal a, and the second signal strength received by the mobile terminal C from the base station C, the distance between the mobile terminal C and the mobile terminal a, respectively, and perform weighted summation on the above values according to a preset weight to obtain the candidate score. And selecting the mobile terminal with the highest candidate score as the target transit terminal.
The scheme can realize the transfer requirement of the first mobile terminal in a larger geographical range, and the transfer service can be obtained from different base stations even if the position of the first mobile terminal is constantly changed.
In summary, in the embodiment of the present invention, when it is determined that the strength of the first signal received by the first mobile terminal from the base station is smaller than the first strength threshold and larger than the second strength threshold, the second mobile terminal that currently starts the communication relay service function is obtained from the target database; and selecting a first target transfer terminal from the second mobile terminal according to the second signal strength received by the second mobile terminal from the base station and the distance between the second mobile terminal and the first mobile terminal. And establishing communication with the first mobile terminal through the first target transfer terminal. In the above scheme, by using the characteristic that the first mobile terminal and the second mobile terminal adopt end-to-end communication, when the received signal strength of the first mobile terminal is smaller than the first strength threshold and larger than the second strength threshold, the base station selects the second mobile terminal capable of providing the relay service as the target relay terminal for the first mobile terminal, so that when the first mobile terminal is disconnected from the base station, the base station resource data can be relayed from the target relay terminal, thereby ensuring the network continuity of the first mobile terminal. According to the scheme, a user does not need to perform any manual operation, and the whole transfer process is regulated and controlled by the base station, so that the user can obtain better communication experience.
Fig. 4 shows a flow chart of a third communication method of an embodiment of the invention. The method is applied to a third mobile terminal, and comprises the following steps:
In this embodiment of the present invention, the third mobile terminal is a mobile terminal located in the vicinity of the first mobile terminal and having a communication relay function. Specifically, when the strength of a first signal received by the first mobile terminal from the base station is smaller than a second strength threshold, the first mobile terminal sends a communication relay request to the neighborhood region in the form of a broadcast message. If a third mobile terminal exists within the range, the third mobile terminal may receive the broadcast message.
The third mobile terminal analyzes the received broadcast message to obtain the equipment identification information, the communication transfer request information, the first signal strength and other information of the first mobile terminal, and the third mobile terminal sends response information to the first mobile terminal according to the information. For example, the response message may include information such as a third signal strength of the third mobile terminal, a distance between the third mobile terminal and the first mobile terminal.
When the first mobile terminal determines that the third mobile terminal can be supported to become the transfer terminal by judging the third signal intensity and the distance, the first mobile terminal determines the third mobile terminal as a target transfer terminal; when there are multiple third mobile terminals, the first mobile terminal may select an optimal target transfer terminal from the third mobile terminals according to the third signal strength and the distance.
In the embodiment of the invention, by receiving a broadcast message from a first mobile terminal, the broadcast message comprises a first signal strength received by the first mobile terminal from a base station; wherein the first signal strength is less than a second strength threshold; and sending a response message to the first mobile terminal according to the first signal strength, so that the first mobile terminal determines a second target transfer terminal from the third mobile terminal according to the response message, and establishes communication with the base station through the second target transfer terminal, so that the third mobile terminal can send the response message to the first mobile terminal according to the broadcast message sent by the first mobile terminal, further the first mobile terminal selects the target transfer terminal, and the base station resource data is relayed from the target transfer terminal, thereby ensuring the network continuity of the first mobile terminal.
