technical field

The present invention relates to the field of network technology, in particular to a base station transmission power configuration method and device.

Background technique

Femtocell is an ultra-miniature mobile base station launched in recent years according to the development of 3G and the trend of mobile broadband. Its size is similar to that of a modem, and it has the characteristics of easy installation, automatic configuration, automatic network planning, and plug-and-play. At present, more and more femtocells are rapidly occupying the market due to their low price and high communication rate, and are widely deployed indoors by users. However, in the actual application process, due to the large number of femtocells used, the strong randomness of the location, and the characteristics of being turned on and off at any time, the traditional network planning and design is not suitable for the optimization and design of the femtocell network, and needs to be more suitable for the femtocell network. Optimization and design techniques to better utilize the advantages of femtocells. The proposal of SON technology is expected to improve the performance of the femtocell network system, and become an important technology for the optimization and design of the femtocell network. Self-Organizing Network (SON) technology includes self-configuration and self-optimization technology, which can automatically sense the wireless environment and adjust its own parameters, thereby bringing about an overall improvement in system performance.

In addition, self-configuration of femtocell base station parameters through SON technology can greatly reduce human participation and operating costs, achieve optimal network performance in terms of coverage, capacity and service quality, and help to achieve a large number of small cell deployments. Therefore, base station transmission power self-configuration has also become the key to the successful deployment of femtocell networks to ensure femtocell network coverage and reduce cross-layer and same-layer interference.

In the existing base station transmission power self-configuration technology, power configuration is often performed only according to the power-on sequence of the base station because the power configuration order of each cell is not considered overall, which leads to unbalanced power configuration and over-coverage and/or weak power configuration. Coverage phenomenon. In addition, in the traditional base station transmission power self-configuration technology, there are often problems of slow convergence and low system performance. For example, when radio link failure (Radio Link Failure, RLF) needs to adjust the power, using the existing technology to measure or collect relevant information needs to collect a large number of measurements, resulting in a slow power adjustment process, and it takes a long time for the base station to adjust to Appropriate power, resulting in slow convergence and low system performance.

detailed description

In order to solve the problems of slow convergence speed and low system performance of base station transmit power adjustment in the prior art, the present invention provides a base station transmit power configuration method and device, and a centralized controller collects detection data reported by all base stations within its jurisdiction. Listening information, respectively based on the listening information reported by each base station, screen out the pilot signal receiving power greater than or equal to the first threshold and the corresponding intercepted base station for the corresponding base station, obtain the first screening result, and according to the first screening result Configure transmit power for each intercepted base station in descending order of occurrence frequency.

Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 1, in the embodiment of the present invention, the specific process of base station transmission power configuration is as follows:

Step 100: The centralized controller collects the interception information reported by all base stations within its jurisdiction. The interception information includes at least the base station identifier of the intercepted base station and the received power of the pilot signal of the intercepted base station. The pilot signal is sent by the listening base station.

Specifically, before the centralized controller collects the interception information reported by all base stations within its jurisdiction, the centralized controller sequentially reads the identifiers of each base station stored locally according to the preset sequence, and indicates the corresponding base station for each base station identifier read. As the intercepted base station, stop sending user data at the interception moment and transmit the pilot signal with the maximum transmission power, and notify other base stations except the intercepted base station within the jurisdiction, turn off the radio frequency at the interception moment and receive the intercepted Listen to the pilot signal transmitted by the base station and measure the received power of the pilot signal.

Specifically, the centralized controller sequentially reads each of the locally stored base station identifiers according to any one of the cell identifiers, IP addresses or physical addresses from large to small or from small to large, and each time a base station is read, it indicates the corresponding As the intercepted base station, the base station stops sending user data and transmits pilot signals with the maximum transmission power at the interception moment, where the base station identifier is any one of cell ID, physical cell ID or frequency point number.

Here, the other base stations other than the intercepted base station will be notified within the scope of jurisdiction as the intercepted base station. The intercepted base station can be a base station with the same frequency or a different frequency with the intercepted base station. However, due to the difference from the intercepted base station The intercepted base station at a higher frequency has less interference with the intercepted base station, and has less impact on the adjustment of the transmission power, so it is not considered as the focus of the present invention.

In addition, the interception information may also include the maximum downlink transmission power value of the intercepted base station, and the maximum downlink transmission power value of the intercepted base station may also be queried through the identity of the intercepted base station to query the corresponding The downlink maximum transmit power value of the intercepted base station.

On the other hand, for the Universal Mobile Telecommunications System (UMTS), the received power of the pilot signal of the intercepted base station in the interception information is the received signal code power of the common pilot channel CPICH (Common Pilot Channel Common Pilot Channel, common pilot channel frequency channel) RSCP (CommonPilot Channel Common Pilot Channel Reference SignalReceiving Power, reference signal receiving power), the maximum downlink transmission power of the intercepted base station is the downlink pilot transmission power of the intercepted base station CPICH TxPower.

or

For the Global System for Mobile Communication (GSM), the received power of the pilot signal of the intercepted base station in the interception information is the received signal level (Receivedsignal level, RXLEV), and the maximum downlink emission of the intercepted base station The power value is the downlink pilot transmission power (Broadcast Control Channel, BCCH) of the intercepted base station.

Step 110: Based on the interception information reported by each base station, the centralized controller screens out the received power of the pilot signal greater than or equal to the first threshold and the corresponding intercepted base station for the corresponding base station, and obtains the first screening result.

Specifically, base stations within the jurisdiction of the centralized controller are sequentially turned on as intercepted base stations according to a preset order. The centralized controller collects the interception information reported by all base stations within the jurisdiction, and according to the interception information reported by each base information, screen out the intercepted base stations whose received power of the pilot signal is greater than the first threshold value, record their corresponding base station identities, and obtain the first screening result. Wherein, the first threshold refers to a target threshold for listening to the coverage edge of the base station.

Step 120: The centralized controller sequentially configures the transmit power for each intercepted base station in descending order of appearance frequency in the first screening result.

Specifically, the first screening result includes a list of intercepted base stations corresponding to each base station sorted by pilot signal received power, and the pilot signal received power of these intercepted base stations is greater than or equal to the first threshold. The centralized controller configures the transmit power for each intercepted base station sequentially according to the base station identification frequency descending order from the intercepted base station list obtained by screening all the base stations.

A higher frequency of appearance of the base station ID indicates that the base station has more neighboring cells, and the interference with the neighboring cells is greater, so the configuration of the transmit power of the base station is prioritized.

Further, after the centralized controller configures the transmission power for each intercepted base station in the first screening result, it continues to screen out the received power of the pilot signal less than the first threshold and the corresponding The intercepted base stations and the preconfigured intercepted base stations that have not been intercepted obtain the second screening result.

The centralized controller sequentially configures transmit power for each intercepted base station in the second screening result.

Therefore, the centralized controller can complete the centralized configuration of the transmission power of all the base stations within the jurisdiction by collecting the interception information reported by all the base stations within the jurisdiction.

The invention points out that the frequency of appearance of the base station identifiers is arranged according to the frequency of occurrence, and the transmission power is configured for them in sequence. In addition, the priority of the coverage target setting priority of the network planning when the base station is deployed can also be configured for the transmission power in sequence. The larger the required coverage, the configuration The higher the priority of the transmit power, or the priority setting is set according to the load of the base station after it is powered on for a period of time, and the transmit power is configured for it in turn. The greater the load, the higher the priority of configuring the transmit power.

In addition, the centralized controller can also handle abnormal situations, including two situations:

Firstly, when the centralized controller determines that a certain base station within its jurisdiction has not detected the interception information of surrounding base stations, it directly configures the transmission power of a certain base station to a preset maximum transmission power value.

Second, when the calculation result of the transmit power of a certain base station by the centralized controller is not within the interval between the maximum transmit power and the minimum transmit power preset by the base station, the transmit power of the base station is configured as the preset transmit power critical value , that is, if the calculated result of the transmit power of the base station is lower than the preset minimum value of transmit power, configure the transmit power of the base station to the preset minimum value of transmit power, or if the calculated result of the transmit power of the base station is higher than If the preset maximum value of transmit power is used, the transmit power of the base station is configured as the preset maximum value of transmit power.

Referring to Fig. 2, the present invention takes the LTE system as an example to describe in detail the specific process of base station transmission power configuration:

Step 201: The centralized controller sequentially activates the Femto base stations within the jurisdiction according to the order of Cell ID size, and other Femto base stations listen to the base stations.

The centralized controller reads the Cell ID of each Femto base station stored locally in sequence according to the size of the Cell ID, and each time it reads a Cell ID, it instructs the corresponding Femto base station to stop sending user data at the time of interception and use the maximum Transmit power to transmit pilot signals, and notify other Femto base stations except the intercepted base station within the jurisdiction, turn off the radio frequency at the time of interception and receive the pilot signal transmitted by the intercepted base station and measure the signal reception of the pilot signal power.

For example, there are four base stations within the jurisdiction of the centralized controller, and the base station identifiers are A, B, C, and D, which are turned on in sequence according to A, B, C, and D, that is, base station A is the first base station to be listened to , base station B, base station C, and base station D are used as intercepting base stations. At the intercepting moment, base station A stops sending user data and transmits pilot signals with the maximum transmission power. Base station B, base station C, and base station D turn off the radio frequency at the intercepting moment and Receive the pilot signal transmitted by the intercepted base station and measure the received power of the pilot signal.

Step 202: The centralized controller uses the Cell ID as an index to record the intercepted information, and collects the intercepted information reported by all Femto base stations within its jurisdiction.

The centralized controller uses the Cell ID as an index to record the interception information intercepted by other base stations except the currently intercepted base station within its jurisdiction. When all base stations within the jurisdiction of the centralized controller are turned on in sequence according to the size of the Cell ID , the centralized controller collects the listening information reported by all the base stations within its jurisdiction for the surrounding base stations.

For example, the interception information of base station A may include interception information for base station B, base station C, and base station D, and the interception information for base station B may include interception information for base station A, base station C, and base station D, so that By analogy, base station C and base station D also report interception information respectively. When all the base stations within the jurisdiction of the centralized controller are turned on sequentially, the centralized controller collects the interception information reported by all the base stations within the jurisdiction of the centralized controller for surrounding base stations.

Wherein, the interception information includes the base station identifier of the intercepted base station, the received power of the pilot signal of the intercepted base station, and the maximum downlink transmit power value of the intercepted base station.

Step 203: The centralized controller obtains an ordered list ConfigureFemto of base stations to be configured with transmit power according to the interception information of all Femto base stations.

For the interception information reported by each base station, the centralized controller screens out the intercepted base stations whose received power of the pilot signal is greater than the first threshold value, records their corresponding base station identifiers, and obtains the screening result.

Further, the centralized controller sorts the occurrence frequency of Cell IDs from high to low according to the screening results of all base stations, and obtains an ordered list ConfigureFemto of base stations to be configured with transmit power.

For example, the interception information of base station A may include the interception information of base station B, base station C, and base station D, wherein, the received power of the pilot signals of base station A for base station B and base station C is greater than the first threshold value, therefore, the concentrated The controller obtains the screening results of the base station A as the base station identifiers of the base station B and the base station C and their corresponding pilot signal received powers. According to the screening results of base station A, base station B, base station C, and base station D, the centralized controller obtains the sequence of appearance frequencies of base station identifiers from high to low as an ordered list of base stations to be configured with transmission power.

Step 204: Start configuring power from the base station whose Cell ID appears most frequently in the list ConfigureFemto.

There are two ways to calculate power:

The first method: P _tx ＝PL _estimation +10*log ₁₀ (10 ^I/10 +10 ^No/10 )+SINR _tar

Among them, the path loss value PL _estimation is the path loss value at which the base station covers the farthest distance from the target, and the farthest point of the coverage target is obtained manually through drive test during the initial network planning of the station deployment, and I is the interference value detected by the base station, which means The approximate interference power on the user UE side estimated by the base station is approximately the RSRP value of the detected neighboring station, No is the estimated background noise of the UE receiver, the typical value is 6-11dB, and the signal-to-noise ratio SINR _tar is the target of the edge UE SINR, the unit is dB, the typical value is -3dB.

The second way: P _tx ＝max(min(α×P _M +β,P _max ),P _min )

In this method, according to the prior art, the base station listens and unbroadcasts to obtain the strongest co-channel signal strength P _M received from the macro station to set its own transmission power. Wherein, P _min and P _max represent the preset maximum value and minimum value of the transmission power respectively.

Further, after the centralized controller configures the transmission power for the above-mentioned list ConfigureFemto, it continues to filter out the pilot signal receiving power less than the first threshold and the corresponding intercepted base station based on the interception information reported by each base station, and the undetected Hear the provisioned listened base station, as ConfigureFemto'.

The centralized controller configures the transmit power for the base stations in the ConfigureFemto' list according to the above calculation method of transmit power.

Therefore, the centralized controller can complete the centralized configuration of the transmission power of all the base stations within the jurisdiction by collecting the interception information reported by all the base stations within the jurisdiction.

In addition, the centralized controller can protect against abnormal conditions. When the centralized controller determines that a base station within its jurisdiction has not detected the interception information of surrounding base stations, it directly configures the transmit power of a certain base station to the preset maximum Transmit power value P _max .

When the centralized controller judges that the calculation result P of the transmit power of a certain base station is not in the interval [P _min , P _max ], it configures its transmit power as a critical value.
