It will be understood by those skilled in the art that fig. 3 is introduced for the purpose of illustrating the basic definition of each time segment, and the length relationship, the proportional relationship, the position relationship and the proportional relationship between the frequency bands between the time segments shown in the figure can be adjusted freely. In summary, the timing structure described in fig. 3 is merely exemplary, and the inventive concepts of the present application are embodied in the claims of the present application.

Fig. 1 is a schematic diagram of a system architecture according to an embodiment of the present invention. The medical service center server can receive relevant medical data, then perform big data analysis, and then obtain a result or judgment. The specific big data judgment method and algorithm are the prior art, and at present, all large Internet intelligent medical companies have a large number of public big data algorithms or provide corresponding big data calculation services.

FIG. 2 is a flow diagram of a method according to an embodiment of the invention. As shown in the figure, the intelligent medical information real-time transmission method based on big data comprises the following steps:

step 101: the first mobile terminal collects the intelligent medical information, the second mobile terminal collects the intelligent medical information, and the third mobile terminal collects the intelligent medical information. Those skilled in the art will appreciate that intelligent medical information is to be understood as information related to intelligent medical treatment.

Step 102: in response to collecting the smart medical information, a first scheduling assignment is sent by the first mobile terminal to the relay mobile terminal on a first set of symbols and a first set of subcarriers of a scheduling assignment transmission period.

Step 103: in response to collecting the smart medical information, a second scheduling assignment is sent by the second mobile terminal to the relay mobile terminal on the first set of symbols and the first set of subcarriers of the scheduling assignment transmission period.

Step 104: the method further includes attempting, by the first mobile terminal, to listen for scheduling assignments transmitted by other mobile terminals during a listening period of a scheduling assignment transmission period, and attempting, by the second mobile terminal, to listen for scheduling assignments transmitted by other mobile terminals during a listening period of a scheduling assignment transmission period.

Step 105: in response to listening to a second scheduling assignment sent by a second mobile terminal on a first set of symbols and a first set of subcarriers of a scheduling assignment transmission period, randomly selecting, by the first mobile terminal, the first set of subcarriers or the second set of subcarriers.

Step 106: if the second set of subcarriers is randomly selected, transmitting, by the first mobile terminal, a first frequency occupancy indicator to the second mobile terminal on a second set of subcarriers and a second set of symbols of the scheduling assignment transmission period, wherein the first frequency occupancy indicator indicates to the second mobile terminal that the second set of subcarriers is occupied, wherein the first mobile terminal transmitting the first frequency occupancy indicator to the second mobile terminal is indicated by the base station. Those skilled in the art should understand that the inter-device communication related to the present application does not require base station coordination, i.e. the base station only allocates D2D communication resource pool to the mobile terminal, and does not control which D2D resources the mobile terminal selects, nor controls the process of avoiding collision of the mobile terminal. In one embodiment, when a mobile terminal requests a D2D pool of communication resources (some documents referred to as a sidelink resource set), the base station may randomly select multiple mobile terminals while indicating to those terminals that, when a collision is detected, the mobile terminals may begin transmitting the frequency occupancy indicator for the first transmission period after the period in which the collision is detected.

Step 107: if the first set of subcarriers is randomly selected, a first frequency occupancy indicator is sent by the first mobile terminal to the second mobile terminal on the first set of subcarriers and a second set of symbols of the scheduling assignment transmission period, wherein the first frequency occupancy indicator indicates to the second mobile terminal that the first set of subcarriers is occupied.

Step 108: in response to listening to a first scheduling assignment sent by a first mobile terminal on a first set of symbols and a first set of subcarriers of a scheduling assignment transmission period, attempting, by a second mobile terminal, to listen to a first frequency occupancy indicator sent by the first mobile terminal on a second set of symbols and a second set of subcarriers of the scheduling assignment transmission period, and attempting, by the second mobile terminal, to listen to the first frequency occupancy indicator sent by the first mobile terminal on a second set of symbols and a first set of subcarriers of the scheduling assignment transmission period, wherein the second mobile terminal listening to the first frequency occupancy indicator sent by the first mobile terminal is indicated by a base station, wherein the second mobile terminal does not send messages in the second set of symbols of the scheduling assignment transmission period. In one embodiment, when a mobile terminal requests a D2D pool of communication resources (some documents referred to as a sidelink resource set), the base station may randomly select multiple mobile terminals and indicate to those terminals that, when a collision is detected, the mobile terminals cannot transmit the frequency occupancy indicator for the first transmission period after the period when the collision is detected, and can only detect the frequency occupancy indicator.

Further, the intelligent medical information real-time transmission method based on big data comprises the following steps: randomly selecting, by the second mobile terminal, the second set of subcarriers or the third set of subcarriers if the second frequency occupancy indicator sent by the first mobile terminal is heard over the second set of symbols and the first set of subcarriers of the scheduling assignment transmission period; in one embodiment, when a mobile terminal requests a D2D pool of communication resources (referred to as a sidelink resource set in some documents), the base station may randomly select multiple mobile terminals and indicate to those terminals that, when a collision is detected (i.e., when a scheduling assignment transmitted by a first mobile terminal is detected), the mobile terminals cannot transmit a frequency occupancy indicator or control information during a first transmission period after the period when the collision is detected, can only monitor the frequency occupancy indicator, and can start transmitting control information after the first transmission period after the period when the collision is detected; randomly selecting, by the second mobile terminal, the first set of subcarriers or the third set of subcarriers if the second frequency occupancy indicator sent by the first mobile terminal is heard on the second set of symbols and the second set of subcarriers of the scheduling assignment transmission period; randomly selecting, by the second mobile terminal, the first set of subcarriers or the second set of subcarriers if the second frequency occupancy indicator sent by the first mobile terminal is heard on the second set of symbols and the third set of subcarriers of the scheduling assignment transmission period; if the first subcarrier set is randomly selected, sending, by the second mobile terminal, a third frequency occupancy indicator to the third mobile terminal on a third symbol set and the first subcarrier set of the scheduling assignment transmission period, wherein the third frequency occupancy indicator indicates to the third mobile terminal that the first subcarrier set is occupied, wherein the sending, by the second mobile terminal to the third mobile terminal, of the third frequency occupancy indicator is indicated by the base station; if the second subcarrier set is randomly selected, sending, by the second mobile terminal, a third frequency occupancy indicator to the third mobile terminal on a third symbol set and the second subcarrier set of the scheduling assignment transmission period, wherein the third frequency occupancy indicator indicates to the third mobile terminal that the second subcarrier set is occupied; if the third subcarrier set is randomly selected, sending, by the second mobile terminal, a third frequency occupancy indicator to the third mobile terminal on a third symbol set and the third subcarrier set of the scheduling assignment transmission period, wherein the third frequency occupancy indicator indicates to the third mobile terminal that the third subcarrier set is occupied; in response to monitoring a first scheduling assignment sent by a first mobile terminal on a first symbol set and a first subcarrier set of a scheduling assignment transmission period, a second scheduling assignment sent by a second mobile terminal on the first symbol set and the first subcarrier set of the scheduling assignment transmission period, and a second frequency occupancy indicator, the third mobile terminal attempts to monitor a third frequency occupancy indicator sent by the second mobile terminal on a third symbol set and the first subcarrier set, the second subcarrier set, and the third subcarrier set of the scheduling assignment transmission period, wherein the third mobile terminal monitoring the third frequency occupancy indicator sent by the second mobile terminal is indicated by the base station.

If the D2D resource pool is reasonably designed, the spectrum resource is rich enough, and the number of the mobile terminals is not too large, the situation that the three mobile terminals select the same subcarrier set at the same time is less, and if the situation that the system load is increased occurs, the situation that the three mobile terminals select the same subcarrier set at the same time occurs, the method ensures that the mobile terminals do not need to receive the control signaling of the base station when the D2D communication is carried out, but because the base station arranges the sending and stopping time of various mobile terminals in advance, the base station in the probability sense is intervened and coordinated in advance, so the method can rapidly reduce the collision probability after few circulating sending-monitoring cycles.

The prior art proposal (3GPP TSG RAN WG1 Meeting #86, R1-167409) of the ITRI organization introduces a D2D communication method, which aims to solve the problem of high probability of UE collision in case of large number of UEs or large number (up to two hundred share one segment of D2D resource pool). It should be understood by those skilled in the art that the proposed solution is directed to a scenario in which the base station does not coordinate the transmission of the mobile terminal D2D, that is, the proposed solution and the present application are directed to a scenario in which the base station allocates the resource pool and various configurations to the mobile terminal in advance through signaling, and then the mobile terminal performs D2D communication with other mobile terminals autonomously without control of the base station. The aforementioned prior art solution (see fig. 5 thereof) proposes that UE 1 and UE2 select frequencies randomly first, then try to send SA, then listen for whether there is SA collision during the listening period, if collision occurs, then UE2 selects other frequency band actively, and UE 1 does not select other frequency band. The problem with this solution is that it does not make clear what the mechanism is that UE2 actively selects other frequency bands, but UE 1 does not, in other words, the technique does not disclose why UE2 actively selects other frequency bands, but not UE 1 actively selects other frequency bands. If the UE randomly selects whether to switch to the other frequency band, the UE 1 and the UE2 probably simultaneously select to switch to the other frequency band, which first causes a waste of frequency resources if both simultaneously switch frequency bands, and at the same time, causes a conflict between both to be not resolved if both switch to the same frequency band. This design loses the basic flexibility if the base station pre-configures UE 1 not to be able to switch frequency bands, and only UE2 is able to switch frequency bands, and in this configuration, UE 1 cannot achieve the most basic frequency diversity gain. In addition, the technology does not relate to how to solve the related technical problem in the situation that if a plurality of UEs exist, and if three UEs simultaneously select the same frequency band, simply applying the technology of fig. 5 in the document will lead to the problem that the conflict resolution time is continuously prolonged. Referring to fig. 6 of the document, it can be found that, when the number of UEs reaches 200, the collision probability remains above 0.3 after 6 rounds of cycles. After using the method of the present application, after simulation, the collision probability of the present application can be optimized by about 20% compared to the prior art after the same time (equivalent time of 6 cycles) as the prior art (the simulation value is slightly affected by specific parameters, such as the transmitting power of the mobile phone, etc., so the value is substantially maintained at about 20%).
