The following describes the process of sampling processing of the UE by taking the sampling period, the length of time for sampling processing in each sampling period, and the starting time of sampling processing in each sampling period as an example:

After receiving the indication command, the corresponding configuration information is valid, and the UE immediately turns on the sampling period timer, and continuously performs any possible D2D communication data from the starting time included in the mode A1 in the sampling period. Sampling processing, until the sampling processing time reaches the length of time included in mode A1, the sampling processing of the D2D data is stopped, and the above process is repeated in the next sampling period. Referring to FIG. 5, where TO is the opening time of the sampling period timer, T is the sampling period (for example, T is 100 ms), T1 is the starting time of the sampling processing, and the UE starts sampling processing at the time T1, at the sampling time. After the set length of time (for example, 40ms) is reached, the sampling process is stopped, and the above process is repeated in the next sampling period;

The sampling period timer may be configured by the network side or by the UE.

It should be noted that whether the sampling period timer is turned on is not related to whether there is currently D2D data transmission, and the UE starts the sampling period timer immediately after receiving the indication command. 2. If the condition of the data sampling is mode A2, then: the UE performs sampling processing according to the set data packet interval. The process of sampling the UE by taking the number of data packet intervals, the number of data packets sampled in each data packet interval, and the sequence number of the initial data packet subjected to sampling processing as an example of the data sampling condition Be explained:

After receiving the indication command, the corresponding configuration information is valid, and the UE immediately turns on the sampling data packet counter (in the process of D2D data transmission by the UE, each time the UE sends or receives a data packet, the sampling data packet counter is added. 1), and in the data packet sampling interval included in the mode A2, the D2D data is continuously sampled according to the set initial data packet number, until the set number of data packets is reached, the sampling of the D2D data is stopped. Process and repeat the above process within the next packet sampling interval. Referring to FIG. 6, where N1 is the starting packet sequence number (for example, the fifth data packet) at which sampling processing is started, and after the UE starts the sampling packet counter, when transmitting or receiving the fifth data packet, Start sampling processing, after reaching the set number of sampling processing packets (for example, 10 data packets), stop sampling processing of D2D data until the sampling interval of the data packet (for example, 100 data packets) ends, and is under The above process is repeated within one packet sampling interval (within 101 200 packets).

Second, the granularity information of the sampled data;

1. If the granularity information of the sampled data is the mode B1, the UE transmits the D2D on the corresponding type of D2D data bearer according to the identification information of the at least one type of D2D data carried in the granularity information of the sampled data. Data is sampled;

Specifically, assuming that the condition of the data sampling is currently satisfied, the UE determines the corresponding D2D data bearer (ie, the target bearer) according to the identifier information of the D2D data bearer included in the granularity information of the sampled data, and carries each target bearer. The D2D data on the sample is sampled.

2. If the granularity information of the sampled data is the mode B2, the UE samples the D2D data of the corresponding service type according to the parameter corresponding to the at least one service type included in the granularity information of the sampled data;

Third, the direction information of the sampled data;

1. If the direction information of the sampled data is mode C1, then: the UE performs sampling processing on the D2D data sent by itself;

2. If the direction information of the sampled data is mode C2, then: the UE samples the received D2D data;

3. If the direction information of the sampled data is mode C3, then: the UE samples and processes the D2D data sent and received by the UE;

Preferably, in order to prevent confusion of the sampled data in different directions, the UE identifies the sampled data in different directions (receiving direction or sending direction) when sampling and processing the transmitted and received D2D data, or in different directions. The sampled data is stored in different registers.

Further, in step 42, the UE performs sampling processing on its own D2D data, including the following two methods: Method 1: The UE extracts the D2D data that satisfies the sampling process directly from the D2D data receiving or sending queue as sample data, and saves The sampled data;

2. If the condition of the upper 4 艮 sample data is the mode D2, then: the UE reports the obtained sample data to the network side when the number of sample data obtained by each sampling process reaches the set threshold value Ν Where , is a positive integer; specifically, the UE starts the reporting counter and starts sampling the D2D data, each time obtaining a sample Data, the value of the counter is incremented by 1. When the value of the counter reaches the set threshold value, the determined sample data is reported to the network side, and the counter is cleared to restart counting; When the value reaches the set threshold again, the one sample data determined this time is reported to the network side, and the above process is repeated;

The threshold value may be a value in units of bits, or a value in units of bytes; the threshold is an empirical value and can be set as needed.

Embodiment 1. The initial configuration and activation process of D2D communication data sampling and reporting, as shown in FIG. 7, includes the following steps:

Step 71: The base station sends a D2D communication data sampling configuration command to the UE1.

The D2D communication data sampling configuration command in this step has the same function as the above-mentioned instruction command;

As an implementation manner, the D2D communication data sampling configuration command carries at least one configuration information related to the D2D communication data sampling mode and/or at least one configuration information related to the D2D communication sampling data. The configuration information related to the D2D communication data sampling mode includes: a condition of the data sampling, a granularity information of the sampled data, and a direction information of the sampled data; and the configuration information related to the D2D communication sampled data reporting manner includes: reporting the granularity information of the sampled data and 4艮 Conditions for sampling data.

As another implementation manner, the configuration command does not carry any configuration information related to the D2D communication data sampling mode and/or does not carry any configuration information related to the D2D communication sampling data reporting manner;

Preferably, if the configuration command does not carry any configuration information related to the D2D communication data sampling mode, the configuration command carries a dedicated cell 1 for instructing the UE to enable the D2D communication data sampling function;

Preferably, if the configuration command does not carry any configuration information related to the D2D communication sampling data reporting manner, the configuration command carries the dedicated cell 2, which is used to instruct the UE to enable the D2D communication sampling data reporting function.

Step 72: The UE1 saves the D2D data sampling configuration command obtained from the base station, and activates the corresponding function according to the configuration information included in the configuration command (including the D2D communication data sampling function and the D2D communication sampling data reporting function);

Further, for the configuration information that is not carried in the configuration command, the UE activates the corresponding function by using the default configuration of the configuration information saved by the UE;

If the configuration command does not carry any configuration information related to the D2D communication data sampling mode, the UE determines whether the D2D communication data sampling function needs to be enabled according to whether the configuration command carries the dedicated cell 1; If the configuration command carries the dedicated cell 1, the UE starts the D2D communication data sampling function; if the configuration command does not carry the dedicated cell 1, the UE does not enable the D2D communication data sampling function;

If the configuration command does not carry any configuration information related to the D2D communication sampling data reporting mode, the UE determines whether the D2D communication sampling data reporting function needs to be enabled according to whether the configuration command carries the dedicated cell 2; If the command carries the dedicated cell 2, the UE starts the D2D communication sampling data reporting function. If the configuration command does not carry the dedicated cell 2, the UE does not enable the D2D communication sampling data reporting function.

Step 73: After activating the D2D data sampling configuration function, the UE1 sends a D2D communication data sampling configuration completion message to the base station;

Correspondingly, after receiving the D2D communication data sampling configuration completion message, the base station confirms that the D2D communication data sampling configuration information has been validated.

Step 74: UE1 starts data communication with UE2 through D2D communication mode.

Step 75: The UE1 transmits the D2D transmitted to the UE2 according to the currently stored configuration information (including the condition of the data sampling, the granularity information of the sampled data, the direction information of the sampled data, the granularity information of the reported sample data, and the condition for reporting the sampled data). Data is sampled;

Further, the UE1 can perform D2D data communication with multiple peer UEs at the same time.

Step 76: The UE1 determines, according to the currently stored configuration information, whether the collected sample data meets the condition for reporting the sampled data.

If yes, go to step 77;

If no, go to step 75;

Step 77: The UE waits to resume the signaling connection with the network side.

Step 78: After the signaling connection is restored, the UE encapsulates and reports the sampled data to the base station by using a control plane bearer or a user plane bearer.

Further, if the current configuration information indicates that the UE samples and processes D2D data transmitted by multiple types of D2D data bearers, multiple service types, or multiple D2D communication links in parallel, the UE encapsulates the sampled data. The packet should carry the identification information of the D2D data corresponding to the sampled data, the identification information of the service type or the identification information of the D2D communication link;

If the current configuration information indicates that the UE simultaneously performs sampling processing on the D2D communication receiving direction and the D2D communication sending direction, and then: the UE encapsulates the D2D communication corresponding to the sampled data in the packet encapsulated with the sampled data. Directional indication.

Embodiment 2: The process of the base station controlling the sampling processing of the D2D communication data by the UE, as shown in FIG. 8, includes the following steps: Step 81: The UE obtains, from the base station, configuration information related to the D2D communication data sampling mode (including obtaining by using a D2D communication data sampling configuration command or a D2D communication data sampling configuration update command);

The configuration information related to the D2D communication data sampling mode includes:

1) conditions for data sampling, by which the base station can control the UE to perform periodic sampling processing or sample processing according to the interval of the data packet;

2) The granularity information of the sampled data, the base station of the sampled data can control the granularity of the sampling process of the D2D communication data by the UE, including sampling by the carrier size, sampling by the service type, or by a D2D communication. The link samples the granularity;

Of course, the base station can control the UE to simultaneously sample at multiple granularities.

3) direction information of the sampled data, through which the base station of the sampled data can control the UE to act on itself

The D2D data sent by the sender of the D2D communication is sampled, or the received D2D data is sampled by the UE as the receiver of the D2D communication, or the D2D communication data of the two directions (the receiving direction and the sending direction) simultaneously Sampling.

Step 82: The UE saves the configuration information related to the D2D communication sampling mode obtained from the base station, and activates the D2D communication data sampling function according to the foregoing information or the default configuration saved by itself, as follows:

1) If the configuration information related to the D2D communication sampling mode includes "conditions of data sampling", the UE enables sampling of its own D2D communication data in the manner indicated in "conditions for data sampling"; if "data sampling is not included" The condition of the UE, the UE performs sampling processing on its own D2D communication data according to the default configuration of the data sampling condition saved by itself, wherein the default configuration of the data sampling condition may be periodic sampling or sampling according to the data packet interval. (Whether the default configuration is based on periodic sampling or sampling according to the packet interval, the UE should also save the default parameters corresponding to this default configuration to ensure the achievability of the method).

2) If the configuration information related to the sampling mode of the D2D communication includes "granularity information of the sampled data", the UE enables sampling of the granularity of the D2D communication data sample indicated by the "particle size information of the sampled data"; if "sample data is not included" The granularity information ", the UE performs sampling processing according to the default configuration of sampling the granularity of the sampled data held by itself, which may be sampled at a granularity of the bearer, sampled at a granularity of the service type, or with a D2D communication link. The granularity is sampled (the UE should also save the default parameters corresponding to the default configuration to ensure the achievability of the method).

3) If the configuration information related to the D2D communication sampling mode includes "direction information of the sampled data", the UE enables sampling of the D2D communication data direction indicated by the "direction information of the UE sampled data". If the "direction information of the sampled data" is not included, the UE performs sampling processing according to the default configuration of the direction information of the communication data saved by itself, which may be a D2D communication reception direction, a D2D communication transmission direction, or a D2D communication dual direction. Step 83: Activate a corresponding function according to the corresponding information item of the configuration information determined in step 82, and determine whether the condition of the data sampling is satisfied in the D2D communication process, and after the condition of the data sampling is satisfied, perform D2D communication data. sampling;

The UE may further include the following two methods in the data sampling process of the D2D communication data:

1) D2D data that satisfies the sampling process is directly extracted from the D2D data transmission or reception queue, and is identified as sample data for storage;

2) The copy of the D2D data satisfying the sampling process is extracted from the D2D data transmission or reception queue and identified as the sampled data for preservation, while the D2D data that satisfies the sampling process itself is still in the D2D data transmission or reception queue.

Embodiment 3: Base station control The process of reporting the D2D communication sampling data by the UE, as shown in FIG. 9, includes the following steps:

Step 91: The UE obtains configuration information related to the D2D communication sample data reporting manner from the base station (including obtaining by using a D2D communication data sampling configuration command or a D2D communication data sampling configuration update command);

The configuration information related to the D2D communication sampling data includes:

1) Reporting the granularity information of the sampled data, including reporting the sampled data by the bearer as the granularity, or reporting the sampled data by using the service type as the granularity (for example, judging the service type according to the QCI parameter of the D2D data corresponding to the sampled data), or A D2D communication link reports sampling data for granularity;

2) The condition for reporting the sampled data, including the periodic triggering reporting method, for example, setting the period timer, after the timer expires, it is considered that the sampling data reporting condition is reached; or setting the sampling data volume threshold value, when collecting the sampling data When the quantity exceeds the threshold, it is considered that the reporting condition is reached;

Step 92: The UE saves the configuration information related to the D2D communication data reporting manner obtained from the base station, and activates the D2D communication data sampling data reporting function according to the foregoing information and/or the default configuration saved by itself, as follows:

1) If the configuration information related to the D2D communication sample data reporting manner includes "granulating information of the reported sample data", the UE enables the "sampled data method" indicated by the "reported sample data granularity information"; if the "reported sampling" is not included The granularity information of the data, the UE enables the default configuration of the granularity information of the reported sample data saved by the UE to report the sampled data, and the default configuration may be to report the data by using the bearer as the granularity, or to sample the data by using the service type as the granularity. 4艮 (for example, judging the service type according to the QCI parameter of the D2D data bearer corresponding to the sampled data), or reporting the sampled data with a D2D communication link as the granularity;

2) If the configuration information related to the D2D communication sample data reporting mode includes the "condition for reporting the sampled data", the UE enables the UE to report the sampled data indicated by the "condition for reporting the sampled data" to determine whether the report condition is reached; if the "reporting" is not included "The condition of the sampled data", the UE enables the default of the "condition for reporting the sampled data" saved by itself. The configuration of the sampled data is reported. The default configuration may be triggered by a periodic mode or by a sampled data threshold.

Step 93: The UE determines whether the obtained sampling data satisfies the reporting condition. If the reporting condition is met, the sampled data is encapsulated into a corresponding format and sent to the base station by using the determined method. The details are as follows:

If it is determined in step 92 that the sampling data is triggered in a periodic manner, after the configuration information is valid, the UE immediately starts the reporting period timer. When the reporting period timer expires, the reporting process of the sampling data is triggered, and the reporting period is triggered. The timer is cleared, and the above process is repeated on the next up cycle.

If the step 92 determines that the sampling data is triggered by the sampled data threshold, the UE immediately turns on the sampling data counter after the configuration information takes effect. When the sampling data reaches the threshold, the upper 4艮 process of the sampling data is triggered. The sampled data counter is cleared to restart the counting process;

If it is determined in step 92 that the sampled data is reported as the bearer, the UE carries the identification information of the D2D data corresponding to the sampled data in the packet header when the sampled data is encapsulated.

If the step 92 determines that the data is sampled by the service type, the UE carries the identification information of the service type (for example, QCI) in the packet header when packetizing the data on the sample.

If the step 92 determines that the sample data is reported by using the D2D communication link as the granularity, the UE carries the identification information of the D2D communication link in the packet header when the sampled data is encapsulated.

Embodiment 4: The update process of the configuration information, as shown in FIG. 10, includes the following steps:

Step 101: The base station sends a D2D communication data sampling configuration update command to the UE, to notify the UE to update the configuration information related to the D2D communication data sampling that has been activated.

1) conditions for data sampling;

2) granularity information of the sampled data;

3) Direction information of the sampled data;

4) reporting the granularity information of the sampled data;

5) Conditions for reporting sampled data.

Step 102: After receiving the D2D communication data sampling configuration update command, the UE performs configuration update on the activated function according to the information item carried by the UE.

Preferably, for the activated work corresponding to the information item not carried in the D2D communication data sampling configuration update command Yes, if the D2D communication data sampling configuration update command includes an "incremental configuration identifier", the activated function remains the original configuration; if the D2D communication data sampling configuration update command does not include an "incremental configuration identifier", the UE will The current configuration of the above activated features is updated with its own saved default configuration.

Step 103: After completing the D2D communication data sampling configuration update, the UE sends a D2D communication sampling configuration update completion message to the base station to notify the base station that the updated configuration information has taken effect.

Embodiment 5: D2D communication data sampling and reporting function Deactivation process, as shown in FIG. 11, includes the following steps: Step 111: The base station sends a D2D communication data sample deactivation command to the UE to notify the UE to deactivate all D2D communication data. Sampling related and activated functions;

The D2D communication data sampling deactivation command in this step has the same function as the above deactivation command.

Step 112: After receiving the D2D communication data sampling deactivation command, the UE deactivates all functions related to D2D communication data sampling, and releases corresponding timers and counters, deletes all data in the register currently holding the sampling data, and releases corresponding data.
