detailed description

Commonly used centralized air interface soft synchronization scheme based on reference station: through network planning, find a reference station (for example: base station 1) in a network. GPS is installed on this base station. Then divide the neighboring stations of the base station into first-level neighboring stations (for example: base station 2, 3, 4, 5, 6, 7), and divide the neighboring stations of the first-level neighboring station into second-level neighboring stations (for example: base station 8- 19)... and so on. The neighboring station on the first floor directly synchronizes the time with the reference station, and the neighboring station on the second floor synchronizes the time with the neighboring station on the first floor... and so on. Until all the base stations in the network are synchronized with the stations of the previous layer.

However, the centralized air interface soft synchronization scheme based on the reference station has several disadvantages:

1. Network planning is required and base station is selected. Planning is difficult, and the distribution of sites in the actual network varies greatly. It is difficult to select the base station, and it is necessary to install GPS for the base station. The relationship between the base station and neighboring stations must be considered comprehensively, for example, it must be a star connection.

2. The deployment is difficult, and high requirements are placed on the selection of reference stations and the installation of GPS. For example, because GPS must be able to search satellites successfully after installation, the GPS antenna installed on the base station must be unobstructed and have a high level of security, such as fire prevention, lightning protection, and anti-theft.

3. The synchronization accuracy is poor, because the synchronization is spread from the base station layer by layer, resulting in the accumulation of errors in the outer base station. The more layers of outer base stations away from the base station, the worse the synchronization accuracy.

In order to solve the above-mentioned problems, this application provides a data processing method. Each base station sends its own adjustment amount (pheromone) to neighboring stations, and uses the adjustment amount of the neighboring station as the input of its next iteration, and repeats iteratively, finally Achieve convergence of the delay deviation between base stations.

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

Figure 1 shows a schematic diagram of a communication system. The communication system may include a first network device 101 and second network devices 102 to 103 connected to the first network device 101. Wherein, the first network device 101 and the second network devices 102 to 103 may be connected through an X2 interface or the like, which is not specifically limited here.

The communication system may be a communication system that supports fourth generation (4G) access technology, such as long term evolution (LTE) access technology; or, the communication system may also support fifth generation (fifth generation) access technology. ( universal mobile telecommunications system, UMTS) access technology; or the communication system can also be a second generation (2G) access technology communication system, such as global system for mobile communications (GSM) access Technology; or, the communication system may also be a communication system that supports multiple wireless technologies, such as a communication system that supports LTE technology and NR technology. In addition, the communication system can also be applied to future-oriented communication technologies.

The first network device 101 and the second network devices 102 to 103 in FIG. 1 may be devices used on the access network side to support terminal access to the communication system, for example, may be base station transceiver stations in a 2G access technology communication system (base transmitter station, BTS) and base station controller (base station controller, BSC), node B (node B) and radio network controller (RNC) in the 3G access technology communication system, 4G access technology Evolved base station (evolved nodeB, eNB) in communication system, next generation base station (gNB), transmission reception point (TRP), relay node (relay node) in 5G access technology communication system ), access point (access point, AP), etc.

In the embodiment of the present application, only one first network device 101 and two second network devices 102 to 103 are taken as examples for schematic description. In actual applications, the communication system in the embodiments of the present application may have more first network devices, second network devices or terminal devices, or fewer second network devices. The embodiment of the present application does not limit the number of the first network device and the number of the second network device.

In the embodiments of the present application, only the first network device and the second network device are base stations as an example for schematic description.

The following describes the data processing method in the embodiment of the present application with reference to the communication system in FIG. 1.

Referring to Fig. 2, an embodiment of the data processing method in the embodiment of the present application includes:

201. The first network device obtains a time adjustment value of the second network device.

The first network device obtains multiple time adjustments corresponding to multiple second network devices. The multiple time adjustments may be sent by multiple second network devices to the first network device, or other devices may collect multiple first network devices. Second, the time adjustment value of the network device is sent to the first network device after the time adjustment, or it may be forwarded by other devices.

The unit of the time adjustment amount in the embodiment of the present application may be seconds, milliseconds, microseconds, or nanoseconds, etc. The specific unit is related to the accuracy actually required, and the specific unit is not limited here.

In the embodiment of the present application, the specific number of the multiple second network devices obtained by the first network device may be 2, or any number of 2 or more. The specific number of the second network devices is never specified here. Make a limit.

The time adjustment value in the embodiment of the present application may be the difference between the system time of two adjacent base stations, the difference between the base station and the reference value, or the reference value, which is not specifically limited here.

Exemplarily, the time adjustment amount of the B base station connected to the A base station obtained by the A base station is 2, the time adjustment amount of the C base station is 3, and the time adjustment amount of the D base station is 4.

202. The first network device determines the weight of the second network device according to the device information of the second network device.

The first network device first obtains the device information of the second network device. The device information may be sent by multiple second network devices to the first network device, or after other devices collect device information of multiple second network devices. What is sent to the first network device may also be forwarded by other devices.

In the embodiments of the present application, according to different device information, there are multiple ways for the first network device to determine the weights of multiple second network devices, which are described below:

1. The device information includes the device type.

The device types in the embodiments of the present application may be reference stations and non-reference stations, and may also be equipment types such as primary base stations and secondary base stations, which are not specifically limited here.

The reference station in the embodiment of the present application is a ground fixed observation station that performs long-term continuous observation of satellite navigation signals, and the communication facility transmits the observation data to the data center in real time or at a fixed time. Among them, the satellite navigation signal can be derived from GPS, Beidou satellite navigation system, etc., and the reference station can also be a station with an accurate clock, such as a 1588V2 system clock, which is not specifically limited here.

When the second network device is a reference station, the second network device can mark the time adjustment amount and send it to the first network device, or the second network device sends another instruction information to the first network device (used to indicate the second network device). The device is a reference station), and the first network device determines that the second network device is the reference station according to the mark and/or instruction information.

After the first network device determines whether the multiple second network devices are reference stations, the weights corresponding to the multiple second network devices are further determined. The second network devices of the reference station can be assigned a higher weight than the second network devices of the non-reference station. The weight of the device is high. That is, when the device type of the second network device is a reference station, the first network device determines that the weight of the second network device is the first weight; when the device type of the second network device is a non-reference station, the first network device determines the second The weight of the network device is the second weight. Among them, the first weight is greater than the second weight.

Exemplarily, following the example in step 201, base station A is connected to base stations B, C, and D. Assume that base station B is a reference station, and base stations C and D are non-reference stations. Then A base station can determine that the weight of B base station is 10, and the weight of C base station and D base station can be further determined according to other factors (traffic volume or handover quantity, etc.), or the weight of C base station and D base station can be directly determined to be two Or a numerical value, for example: A base station directly determines that the weight of C base station is 3, and A base station directly determines that the weight of D base station is 1 (that is, the first weight is 10, the second weight is 1, and 3 is the first weight or the second weight ) Or base station A directly determines that the weights of base stations C and D are both 1 (that is, the first weight is 10, and the second weight is 1). Of course, the three weights assigned can also add up to 1, that is, base station A can determine that the weight of base station B is 0.8 (first weight), and the weight of base station C and D is 0.1 (second weight). The specific method of weighting is not limited here.

2. Device information includes traffic volume.

The first network device obtains the traffic volume of the second network device, and compares the traffic volume with the first preset threshold to further determine the weight of the second network device.

The definition of traffic volume: the product of the average number of calls occurring within T and the average occupancy duration.

The calculation formula of the traffic volume is as follows: A=C _T ·t. Among them, A is the traffic volume, t is the average occupancy time of each call, and C _T is the average number of calls. Traffic unit: hourly call, minute call, and hundred-second call. Generally, the time range of statistics is 1 hour, so the traffic volume is also called hourly call. The unit of measurement for traffic is Ireland (erlang, Erl). The first preset threshold given in the embodiment of the present application can be set according to actual needs, for example, 1Erl, etc.

The second network device can send its own traffic to the first network device, and the first network device compares the traffic with the first preset threshold, or compares the result (the traffic with the first preset threshold). The relationship between the size of) is sent to the first network device.

When the traffic volume of the second network device is greater than (or greater than or equal to) the first preset threshold, the first network device determines that the weight of the second network device is the third weight; when the traffic volume of the second network device When it is less than or equal to (or can be less than) the first preset threshold, the first network device determines that the weight of the second network device is the fourth weight, and the third weight is greater than the fourth weight. Among them, the first preset threshold is set according to actual needs, and the specific value is not limited here.

Exemplarily, following the example in step 201, base station A is connected to base stations B, C, and D. Assuming that the first preset threshold is 1Erl, and the traffic volume of base station B is 2Erl, the traffic volume of base station C is 0.8Erl, and the traffic volume of base station D is 0.9Erl, base station A can determine that the weight of base station B is 9 , The weight of C base station and D base station can be further determined according to other factors (device type or number of handovers, etc.), or the weight of C base station and D base station can be directly determined to be a certain two or one value, for example: A base station directly determines C base station The weight of base station A is 4, base station A directly determines the weight of base station D as 2 (that is, the third weight is 9, the fourth weight is 2, and 4 is the third weight or the fourth weight) or base station A directly determines the weights of base stations C and D Both are 2 (that is, the third weight is 9 and the fourth weight is 2). Of course, the three assigned weights can also add up to 1, that is, base station A can determine that the weight of base B is 0.7 (third weight), and the weight of base C and D is 0.15 (fourth weight). The specific method of weighting is not limited here.

3. The device information includes the number of switches between the first network device and the second network device.

The first network device determines the number of switching (number of users or switching times) corresponding to the first network device and the plurality of second network devices. The user here mainly refers to a terminal device (such as a mobile phone, a tablet computer, a smart watch, etc.). Taking a mobile phone as an example, handover refers to: the mobile phone switches from communicating with the first network device to communicating with the second network device, or the mobile phone switches from communicating with the second network device to communicating with the first network device.

The number of switching in the embodiment of this application is the number of switching of users or the number of switching of users within a certain time range. The time range can be 30 minutes, 1 hour, 1 day, etc. The time range can be set according to actual needs, specifically here Not limited. For example, within a certain period of time, the mobile phone switches from communicating with the first network device to communicating with the second network device, and then switches from communicating with the second network device to communicating with the first network device. In this case, the number of switching can be 1 (that is, only one mobile phone is switched) or 2 (the number of times the mobile phone is switched), which is set according to actual needs, and the specific number is not limited here.

When the number of switching between the second network device and the first network device is greater than (or greater than or equal to) the second preset threshold, the first network device determines that the weight of the second network device is the fifth weight; When the number of handovers between the network device and the first network device is less than or equal to (or less than) the second preset threshold, the first network device determines that the weight of the second network device is the sixth weight. Among them, the fifth weight is greater than the sixth weight.

Exemplarily, following the example in step 201, base station A is connected to base stations B, C, and D. Assuming that the second preset threshold is 10 times (the time range is half an hour), and within half an hour: the number of users handed over between base station A and B is 8, and the number of users handed over between base station A and C is 11 times, the number of users handed over between A base station and D base station is 15 times. Then the A base station determines that the weight of the B base station is 1, the weight of the C base station is 8, and the weight of the D base station is 9 (that is, the fifth weight is 9, the sixth weight is 1, and 8 is the fifth weight or the sixth weight). Of course, the higher the number of switching between the second network device and the first network device, the larger the assigned weight. In addition, the three assigned weights can add up to 1, that is, base station A can determine that the weight of base station B is 0.1, the weight of base C is 0.4, and the weight of base D is 0.5 (that is, the fifth weight is 0.5, and the sixth weight is 0.1, 0.4 is the fifth weight or the sixth weight). The specific method of weighting is not limited here.

It is understandable that the first network device can determine the weight of the second network device according to one or more of the above three kinds of device information (that is, the device information includes at least one of the device type, the traffic volume, and the number of handovers, etc.) .

In the embodiments of this application, the above three situations of device information are just examples. It is understandable that in specific applications, there may be other ways. For example, device information includes reference signal receiving power (RSRP), signal The signal to interference plus noise ratio (SINR), the accuracy of the measurement volume (accuracy is characterized by measurement error, for example, the synchronization accuracy threshold is 1.5us, if the air interface measurement error is greater than 1.5us, That means that the accuracy of the air interface measurement is poor, and it cannot support the system to reach the synchronization accuracy threshold of 1.5us), and the credibility of the interactive time information {base stations exchange information with each other, but the information exchange may also have packet loss and delay problems. For example, the interaction delay is too large, greater than 10s (the threshold is not fixed, different system definitions are different, here 10s is only an example), etc., the information of this interaction is considered to be unreliable} or each base station is in the cluster (Cluster )/Connectivity in the network (the degree of nodes, that is, the number of neighboring stations of each base station), etc., which are not specifically limited here.

203. The first network device determines the target system time of the first network device according to the time adjustment amount and the weight.

After the first network device determines the weights corresponding to the multiple second network devices, the first network device determines the target time adjustment amount of the first network device according to the multiple time adjustment amounts and the multiple weights.

In the embodiments of this application, there are multiple calculation methods for the target adjustment amount, which are described below:

1. Determine the target time adjustment amount according to the device type.

The first network device determines the target time adjustment amount according to the device type of the second network device and the time adjustment amount.

Exemplarily, the time adjustment amount of the B base station is 2, the time adjustment amount of the C base station is 3, and the time adjustment amount of the D base station is 4. Continuing the three examples of device types in step 203, the process of calculating the target adjustment amount is as follows:

1.1. If the weight of the B base station is 10 (the first weight), the weight of the C base station is 3, and the weight of the D base station is 1 (the second weight), the target adjustment amount is:

1.2. If the weight of the B base station is 10 (the first weight), and the weights of the C and D base stations are both (the second weight), the target adjustment amount is:

1.3. If the weight of the B base station is 0.8 (the first weight), the weight of the C base station and the D base station is 0.1 (the second weight). The target adjustment amount is:

2. Determine the target time adjustment amount according to the traffic volume.

The first network device determines the target time adjustment amount according to the traffic volume and the time adjustment amount of the second network device.

Exemplarily, the time adjustment amount of the B base station is 2, the time adjustment amount of the C base station is 3, and the time adjustment amount of the D base station is 4. Continuing the example of setting the traffic volume in step 203, there are two ways to calculate the target adjustment volume:

2.1. If the weight of the B base station is 9 (the third weight), the weight of the C base station is 4, and the weight of the D base station is 2 (the fourth weight), then the target adjustment amount is:

2.2. If the weight of the B base station is 9 (the third weight), and the weights of the C and D base stations are both 2 (the fourth weight), the target adjustment amount is:

2.3. If the weight of the B base station is 0.7 (the third weight), the weight of the C base station and the D base station is 0.15 (the fourth weight). The target adjustment amount is:

3. Determine the target time adjustment amount according to the number of switching.

The first network device determines the target time adjustment amount according to the number of handovers and the time adjustment amount.

Exemplarily, the time adjustment amount of the B base station is 2, the time adjustment amount of the C base station is 3, and the time adjustment amount of the D base station is 4. Continuing the example of the switching quantity in step 203, there are two ways to calculate the target adjustment amount:

3.1. If the weight of the B base station is 1 (the sixth weight), the weight of the C base station is 8 and the weight of the D base station is 9 (the fifth weight), the target adjustment amount is:

3.2. If the weight of the B base station is 0.1 (the sixth weight), the weight of the C base station is 0.4, and the weight of the D base station is 0.5 (the fifth weight). The target adjustment amount is:

In the embodiments of the present application, there are multiple calculation methods for the target adjustment amount, and the above methods are just examples, and the details are not limited here.

After the first network device calculates the target adjustment amount, the first network device increases the target time adjustment amount on the basis of the initial system time to obtain the target system time.

Exemplarily, the target adjustment amount is 3.4 microseconds, the initial system time is 22:25:43, 5 microseconds, and the target system time is 22:25:43, 8.4 microseconds.

Optionally, to achieve more accurate time synchronization between the first network device and the second network device. Steps 201 to 203 can be executed cyclically (iteratively) until the preset condition is satisfied. The preset condition can be that the number of cycles reaches a preset value (for example, the preset value is 30 times or 50 times, etc.) or the adjustment amount is less than N consecutive times. The synchronization accuracy threshold, N is a value greater than or equal to 1, and the synchronization accuracy threshold is set according to actual needs, generally 1.5 microseconds.

Steps 201 to 203 can be executed cyclically using the following formula:

in,

Is the K-th time adjustment of base station A, β is the weight determined according to the equipment information of the first neighboring station adjacent to base station A,

Adjust the amount of time for the first neighboring station. α _Aj represents the weight of multiple second neighboring stations adjacent to the first neighboring station,

Indicates the time adjustment amount of multiple second neighboring stations.

Through the cyclic execution of steps 201 to 203, the base station interacts with the neighboring station to adjust the time, and calculates the next time adjustment of the base station according to the received iteration information of the neighboring station. After multiple iterations, convergence is achieved.

That is, after the first network device obtains the target system time, it can continue to obtain the new time adjustment amount of the second network device and assign a new weight, and then determine the new target adjustment amount according to the new weight and the new time adjustment amount.
