It illustrates, it is assumed that the battery dump energy state for obtaining terminal is 10%, and battery capacity in second threshold is arranged Threshold value is 20%, since the battery dump energy state of terminal is less than second threshold, since terminal is direct by telecommunication It being communicated with the Internet of Things base station, power consumption is high, it is thus necessary to determine that at least one link terminal, according to the relaying Terminal is forwarded by short distance ad hoc network and is communicated with the Internet of Things base station.
In embodiments of the present invention, when determining the communication mode for carrying out data transmission of internet of things, can also consider simultaneously The communication link state of Internet of Things base station and the available resources state of terminal, specific to determine that rule be manually set, this hair Bright embodiment does not repeat them here it.
Optionally, in embodiments of the present invention, the communication mode of the terminal can be pre-set single communication side Formula can be set to closely for example, the communication mode of terminal can be set to telecommunication mode or the communication mode of terminal The communication mode of distance communication.
Step S101, carried out data transmission by the determining communication mode with Internet of Things base station, wherein the communication Mode includes directly being communicated and being forwarded by short distance ad hoc network and institute with the Internet of Things base station by telecommunication Internet of Things base station is stated to be communicated.
In the embodiment of the present invention, according in the available resources state of the communication link state of Internet of Things base station and terminal extremely One item missing determines the communication mode for carrying out data transmission of internet of things；It is carried out by the determining communication mode and Internet of Things base station Data transmission, wherein the communication mode includes directly being communicated and being led to the Internet of Things base station by telecommunication The forwarding of short distance ad hoc network is crossed to be communicated with the Internet of Things base station.By telecommunication directly with the Internet of Things base station The mode communicated can guarantee with the communication quality of the preferable terminal of the communication link state of Internet of Things base station, pass through low coverage The mode communicated with the Internet of Things base station is forwarded from ad hoc network, is forwarded using link terminal, is not being increased Internet of Things In the case where netting the power consumption of base station and not increasing Internet of Things base station number, by the flexible networking of terminal room, guarantee covering side Communication quality between terminal in edge and coverage hole and Internet of Things base station, and reduce operation cost.
Below by two specific embodiments, in the method for data transmission by telecommunication directly with the Internet of Things Net base station carries out communication and is communicated by the forwarding of short distance ad hoc network with the Internet of Things base station to be described in detail respectively.
Specific embodiment one, terminal receive the first signal that Internet of Things base station is sent, and are judged eventually according to first signal The communication link state of end and Internet of Things base station is preferably higher than first threshold, and terminal available resources state is higher than second threshold, eventually End can guarantee reliable communication with Internet of Things base station, and terminal can directly be carried out with the Internet of Things base station by telecommunication Communication, it is specific as shown in Fig. 2, T1 and Internet of Things base station use telecommunication, specifically, logical using remote authorization frequency point Letter, wherein shown authorization frequency point is that operator or other frequency resource management organizations are specified, is used when carrying out data transmission The specified NB-IoT agreement of operator, keeps wireless communication interface consistency.
Specific implementation two, terminal detect battery dump energy state, available communication flow and the available communication number of itself One of or it is a variety of, when one of the battery dump energy state, available communication flow and available communication number or more When kind is lower than second threshold, terminal determines link terminal, is carried out data transmission by the link terminal and Internet of Things base station, In, the link terminal can be one, or it is multiple, as shown in Fig. 2, T2 is when the link terminal is one Terminal is then communicated by link terminal T1 with Internet of Things base station；When the link terminal be it is multiple when, when Tn be terminal, Second level link terminal T1 is then forwarded the data to by level-one link terminal T2, second level link terminal T1 forwards the data to Internet of Things Net base station, wherein pass through low coverage before terminal Tn and level-one link terminal T2, level-one link terminal T2 and second level link terminal T1 It is communicated from unauthorized frequency point, wherein the terminal for needing link terminal to forward is in the covering edge of Internet of Things base station or covers blind Area, the process when terminal and Internet of Things base station for covering edge and coverage hole carry out data transmission hereinafter will do it more in detail Thin elaboration explanation.
Terminal can pass through following two mode when determining candidate relay terminal.
Mode one, terminal are in the network of ad hoc network, and suitable node conduct can be found in the node in network Relaying, wherein the resource information of the terminal in the network of ad hoc network is stored in local maintenance by the node, that is, terminal, terminal In terminal list, the query candidate link terminal in terminal list.
Mode two, terminal are not in the network of ad hoc network, and terminal initiates the ad hoc network of short-range communication, pass through establishment The mode of network finds surroundings nodes, and finds suitable node as link terminal in surroundings nodes.
It is the detailed of process when carrying out data transmission to the terminal at covering edge and coverage hole with Internet of Things base station below Thin elaboration explanation.
Example one, when terminal is in Internet of Things base station covering edge, terminal is realized by link terminal and Internet of Things The remote data transmission of base station.As shown in Figure 3, it is assumed that the terminal for covering edge is T2, and the detection part in T2 monitors and object The signal strength of internet base station and signal quality are less than first threshold, it cannot be guaranteed that with the reliability of Internet of Things base station communication then T2 Surroundings nodes are obtained, and monitor battery dump energy state, available communication flow and the available communication number of surroundings nodes, are such as schemed Shown in 3, the surroundings nodes that T2 is monitored are T1, T3, T6, T7, wherein the number that T2 obtains surroundings nodes depends on the storage of T2 Ability, the sensitivity of detection, and the actual number for node of around arranging net.T2 selects rule to determine itself by following four Link terminal.
The optimal link terminal of rule one, selection communication quality, detailed process are as shown in Figure 4:
Step S400, T2 receives the signal of surroundings nodes, determines the signal strength and signal quality of surroundings nodes, wherein The signal strength can for received signal intensity instruction (Received Signal Strength Indication, RSSI), the signal quality can be examine signal receiving quality (Reference Signal Receiving Quality, RSRQ), signal-to-noise ratio (Signal-to-noise ratio, SNR), received signal code power (Received Signal Code Power, RSCP), one of Reference Signal Received Power (Reference Signal Receiving Power, RSRP), The embodiment of the present invention can select SNR.
For example, T2 monitors that surroundings nodes are T1, T3, T6, T7.
Step S401, judge whether the signal strength of T2 surroundings nodes and signal quality meet the short-range communication matter of setting The threshold value of amount and communication strength.
If step S4021, T2 signal strength according to present in surroundings nodes and signal quality, which determine, meets the close of setting The node of distance communication quality and communication strength will then meet the short-range communication quality of setting and the section of communication strength as standby Select node, i.e. candidate relay terminal.
For example, T2 judges that T1, T6, T7 meet the short-range communication quality and communication strength of setting, then T1, T6, T7 are to wait Select link terminal.
If step S4022, T2 is determined according to the signal strength and signal quality being not present in surroundings nodes meets setting The node of short-range communication quality and communication strength, then by all alternately nodes around T2, i.e. candidate relay terminal.
For example, T2 judges T1, T3, T6, T7 is unsatisfactory for the short-range communication quality and communication strength of setting, then T1, T3, T6, T7 are candidate relay terminal.
Step S403, after step S4021 and S4022, T2 is in the candidate relay terminal in selection signal quality The best node of Signal to Noise Ratio (SNR) is as best candidate link terminal.
For example, the node T1 that T2 selects signal-to-noise ratio best is best candidate link terminal.
Step S404, T2 judges whether the quantity of the connected terminal of best candidate link terminal reaches peak load, If so, the best candidate link terminal is deleted, return step S403, if it is not, thening follow the steps S405.
For example, T2 judges that the quantity of the connected terminal of T1 does not reach peak load.
Step S405, T2 determines that the best candidate link terminal is link terminal.
For example, T2 judges T1 for link terminal.
In the embodiment of the present invention, if stopping link terminal if above-mentioned steps are performed a plurality of times can not find terminal always Search process, it is believed that T2 can not be attached by way of ad hoc network with Internet of Things base station.
Rule two takes into account communication quality, and selects the connection least link terminal of terminal quantity, detailed process such as Fig. 5 institute Show:
Step S500, T2 receives the signal of surroundings nodes, determines the signal strength and signal quality of surroundings nodes.
For example, T2 monitors that surroundings nodes are T1, T3, T6, T7.
Step S501, judge whether the signal strength of T2 surroundings nodes and signal quality meet the short-range communication matter of setting The threshold value of amount and communication strength.
If step S5021, T2 signal strength according to present in surroundings nodes and signal quality, which determine, meets the close of setting The node of distance communication quality and communication strength will then meet the short-range communication quality of setting and the section of communication strength as standby Select node, i.e. candidate relay terminal.
For example, T2 judges that T1, T6, T7 meet the short-range communication quality and communication strength of setting, then T1, T6, T7 are to wait Select link terminal.
If step S5022, T2 is determined according to the signal strength and signal quality being not present in surroundings nodes meets setting The node of short-range communication quality and communication strength, then by all alternately nodes around T2, i.e. candidate relay terminal.
