detailed description

The specific embodiments of the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. As shown in FIG. 1 , it is a schematic block diagram of an embodiment of a method for planning a wireless network according to the present invention. This embodiment can implement automatic wireless network planning of a base station (BTS, Base Transceiver Station). The base station may be: a Femtocell base station, an AP base station, a pico base station, and a base station such as a common base station. The Femtocell base station is taken as an example to illustrate a method for planning a wireless network according to the present invention. The method includes:

 S101: After determining the installation bit, the Femtocell base station obtains network planning algorithm information, such as frequency band characteristics and frequency planning rules, from the core network (CN). For example, after the power is turned on, the Femtocell base station sends a REQUEST (Access Request) message to the CN to request to obtain network planning algorithm information such as a frequency band characteristic and a frequency planning rule from the CN, where the CN is received. After the REQUEST message, the network planning algorithm information such as the frequency band characteristics and the frequency planning rule stored by the UE is sent to the CN, or the Femtocell base station obtains the response of the CN about the REQUEST message, and the CN is obtained from the CN. Search and download the network planning algorithm information such as the frequency band characteristics and frequency planning rules.

 The network planning algorithm information obtained by the base station from the CN includes, but is not limited to, one or any combination of the following information: a frequency band characteristic, a frequency planning scheme, an initial sector identification code planning algorithm, a neighboring area algorithm, and a location area algorithm. A series of corresponding algorithm rules, parameters, and template information, such as the maximum value of uplink and downlink power, access parameters, load balancing parameters, power control parameters, or handover parameters.

 Wherein, for a WIMAX system, the sector identification code may be a preamble value. For the GSM system, the sector identification code may be a BSIC, for a CDMA, UMTS, UMB, or LTE system, the sector identification code may be a scrambling code.

 In this embodiment, the Femtocell base station in the WIMAX system is taken as an example. Therefore, the sector identification code in this embodiment is a preamble value.

 The specific implementation of the Femtocell base station to determine the installation location can take the following measures: For a plug-and-play device such as a Femtocell base station, the installation can be completed by the terminal user. The method of selecting the installation bit can be performed by using the instructions in the user manual. Or you can use Smart Boot to help select the installation location you need. The intelligent guidance, for example, uses the interference status indication of the base station or the method of terminal assisted intervention to guide the user to select the installation location.

The interference status indication is, for example, setting an interference status information identifier on the Femtocell base station, and the Femtocell base station compares the received total bandwidth power with a preset decision threshold value. Compare, and compare the results to indicate the corresponding degree of interference. The identifier may be an indicator light that can display different colors (such as red, yellow, and green), and different degrees of interference are indicated by displaying different colors. Of course, other identification means may also be used, such as using different prompt sounds. Indicates different levels of interference, etc.

 S102: The Femtocell base station performs radio network planning according to the acquired network planning algorithm information to implement automatic configuration of the base station. The automatically configured parameters may include, but are not limited to, one of a frequency point parameter, a neighboring area parameter, a leading parameter, a location area parameter, a maximum power parameter, an access parameter, a load balancing parameter, a power control parameter, or a switching parameter, or A variety. The automatically configured base station can perform normal work, such as voice call or packet transmission. Of course, the wireless network planning of the foregoing base station may be performed automatically. During the planning process, the base station may also interact with the CN to update the required network planning algorithm information, or provide corresponding detection parameters for the CN. The wireless network plan may specifically include one or more of the following steps:

 A. Frequency point selection: The Femtocell base station starts a scanning mode, and selects a frequency of use from each frequency point of the current frequency band according to a frequency plan scheme downloaded from the CN. The selected frequency of use may be a frequency point with a minimum interference among a plurality of frequency points in the frequency band, and a method for selecting the frequency point, for example: the Femtocell base station calculates interference of each frequency point in the frequency band, and obtains the receiving power. RSS (Received Signal Strength Indicator) and carrier-to-interference ratio (C/I, carrier-to-interference ratio), and then select the frequency of the highest and highest interference from these frequencies, as the Femtocell base station. Frequency. At the same time, the Femtocell base station also reports the frequency of use to the CN, so that the CN is used as an initial value when subsequently interacting with the Femtocell base station.

 Specifically, according to the frequency plan, the method of selecting the frequency point is selected, for example, when the 1.25 MHz base frequency is used as the frequency of the Internet, the frequency of the 20M / 30M band is 16/24. . The Femtocell base station scans the full frequency band supported by the system when selecting the frequency point, and obtains the frequency of the RSSI and C/I weighting on the uplink and downlink as the frequency of use, so as to ensure the coverage of the Femtocell base station. Edge throughput.

Certainly, in order to improve the average throughput of the entire sector of the Femtocell base station, the terminal can continuously monitor the bandwidth occupation, RSSI, and C/I of each frequency band during the call process using the Femtocell base station, and the terminal is closer to the Femtocell base station. When, C/I will increase, so you can choose more frequencies. Rate bandwidth, or use a higher modulation method, thereby increasing the average throughput of the entire sector, which is multi-ring FFR frequency reuse.

 In addition, in addition to considering the frequency interference between the Femtocell base stations, the frequency interference between the Femtocell base station and the macrocell can be considered, for example: 20 MHz bandwidth, macrocell uses 15M frequency band. The bandwidth is for the three-sector networking of PUSC 1 x3, and the remaining 5M band is used for the Femtocell base station (of course, when interference is allowed, the 15M bandwidth used by the macro cell can also be used for pico/Femtocell). This additional 5M bandwidth is used as the frequency of use of the Femtocell base station and is dynamically allocated according to the minimum interference principle of the Femtocell base station scanning measurement.

 B. Neighboring area planning: The Femtocell base station performs automatic initialization planning on the relevant neighboring area according to the neighboring area algorithm rule downloaded from the CN, for example, updating the neighboring area relationship. At the same time, the related neighbor list is refreshed, so that after the power is turned on, the neighbor list can be used to perform corresponding work, for example, the cell with the neighbor relationship can be preferentially measured to improve the measurement efficiency, and the updated neighbor relationship can be increased. Neighboring areas can also be reduced neighborhoods.

 For example, the method for updating the neighbor relationship is as follows: The Femtocell base station performs signal strength ordering on the neighboring cells, and adds a predetermined number of cells with the previous signal strength to its own neighboring cell. For example, after the Femtocell base station is powered on, the scan mode is started, and the neighboring cell signals are scanned and searched, and the calculation results are sorted according to the signal strength by the internal cells, such as the integral calculation, and the signal is sorted according to the signal strength. The cell with the strongest strength starts to calculate, and sequentially increases the number of cells whose signal strength is ranked in front to the neighboring cell.

 C, initial preamble (Preamble) value selection: Femtocell base station obtained from S102

The initial Preamble value for the base station is obtained in the Preamble planning algorithm template. At the same time, after the power is turned on, the Femtocell base station needs to detect whether the initial Preamble value is occupied by other Femtocell base stations in the neighboring area (such as the neighboring area), and if occupied, combine the base station obtained from the configuration database of the core network side. a neighbor list (which may also be obtained by step B), and then select a Preamble value that is not occupied by the base station according to the neighbor list; otherwise, the initial Preamble value is still used for terminal access. Identification when the network. At the same time, the initial Preamble value can also be updated with the newly selected Preamble value.

The method for selecting the Preamble value may be, but is not limited to, the neighboring cell list of the configuration database. The other base stations that have the smallest delay to reach the Femtocell base station (such as Femtocell) are obtained. a multiplexed Preamble group in which the base station or the macro cell base station is located (the multiplexed Preamble group can be obtained from the core network or detected by the base station), and select a Preamble from the multiplexed Preamble group that is not occupied by the base station. value. For example, first, select the other Femtocell base station that has the smallest delay to reach the Femtocell base station, or the Preamble value of the multiplexed Preamble group where the macrocell base station is located. If the Preamble value of the multiplexed Preamble group is used up, select the arrival point. The Preamble value of the multiplexed Preamble group where the Femtocell base station has a small delay, and the other Femtocell base station or the macrocell base station where the femtocell base station is located. And so on. The selected Preamble value is then updated to the initial Preamble value.

 It should be noted that, after selecting the available Preamble value according to the foregoing method, the mutual isolation state between the Femtocell base station and other Femtocell base stations may be further considered in combination with the network neighboring cell list, thereby avoiding the Preamble caused by the interlaced base station. The call drop caused by the value multiplexing is incorrect.

 For example, as shown in FIG. 2, it is a state diagram of a neighboring base station. If the Femtocell base station A is adjacent to the Femtocell base station B and has already entered the network, a Femtocell base station C is added to make the Femtocell base station C and the Femtocell base station B adjacent. . Then, the Femtocell base station C selects the reamble value as 1 when it detects that the Femtocell base station B is its neighboring cell and detects that the neighboring area whose neighboring preamble is 1 is not used. As the Femtocell base station B and the Femtocell base station C increase the neighbor relationship, the Femtocell base station B finds that the neighboring area with the preamble 1 already exists (ie, is used by the Femtocell base station A) through the periodic neighbor self-test. The Femtocell Base Station C is forced to re-select its own preamble value until it is inconsistent with the neighbor's preamble value.

 In addition, if the Preamble values of all the multiplexed Preamble groups are occupied, the Preamble value of the Preamble group with the weakest signal strength may be selected to update the initial Preamble value of the Femtocell base station. It should be noted that the transmit power of the Femtocell base station and the emtocell base station of the Preamble group needs to be reduced.

 D, automatic location area planning:

 When the Femtocell base station enters the network, it needs to plan its own location area according to the location area algorithm rule downloaded from the CN, so that the terminal therein can respond to the paging.

The method of location area planning is as follows: Method 1: When the Femtocell base station is powered on, the neighboring area signal strength search is used to obtain its neighbor relationship, and then the location area of the Femtocell base station is set to the location area where the neighboring areas are located according to the downloaded location area algorithm rule. The CN may also set a permissible base station/sector carrier frequency for each location area, and set redundancy to control the number of base stations in a location area.

 When the number of base stations in a location area reaches full and there is a new base station in the coverage area of the location area, a new location area number is used for the newly added base station.

 In addition, in order to prevent frequent location update registration between the location area and the location area, it is necessary to set the number of zones based on the location registration. For example, the number of zones can be set to 2 to prevent frequent registration at the location zone boundary. Causes problems that cannot be paged.

 In addition, in order to prevent the macro cell location area from planning the paging bandwidth (or the number of sector carriers) to be limited, the micro cell and the macro cell can be planned to different location areas in the form of a hierarchical network, for example, when the network where the Femtocell base station is located is not When considering the signal, consider using a macro cellular network.

 Method 2: When the user purchases the Femtocell base station, the address to be placed is registered in the background. The background area sets its own location area to the location area where the Femtocell base station adjacent to the geographical area where the installation address is located according to the downloaded location area algorithm rule.

 E, uplink and downlink power control.

 This step is an auxiliary measurement performed in order to be able to determine the power more accurately after the Femtocell base station acquires the maximum value of the uplink and downlink power in S102. Its control method is as follows:

 When the device is in the self-test, the device randomly dials the test number when it is close to the Femtocell base station, and then calculates the maximum transmit power of the Femtocell base station channel (ie, the maximum downlink transmit power) according to the blocking threshold of the terminal receiving the RSSI. . Then, according to the sensitivity of the base station or the terminal, under the premise that the uplink and downlink path loss are consistent, the uplink and downlink are balanced, for example, according to "uplink transmit power - downlink transmit power + uplink sensitivity - downlink sensitivity = 0", the uplink maximum is obtained. The value of the power.

 In addition, in the foregoing S101, the Femtocell base station may further apply, to the CN, to download initial default configuration parameters and software configuration data used for the network access operation of the base station, for example, a service channel maximum power, an access parameter, a load balancing parameter, Power control parameters, switching parameters, etc.

Furthermore, the above embodiments can be applied to pico base stations, ap base stations, and ordinary base stations in addition to the Femtocell base stations. The network planning methods of these base stations are similar to the above methods, and are not described here. It should be noted that the ap base station can select the installation bit and the antenna feed according to the method of the Femtocell base station. In addition, if a pico base station or a common base station is used, then a theoretical site needs to be simulated first, and then the The theoretical site conducts on-site surveys to determine the actual site.

 At the same time, the automatic wireless network planning method of the Femtocell base station under the WIMAX system described above is applicable to the UMB and LTE systems of network evolution, in addition to the GSM, CDMA, and UMTS systems. The preamble planning algorithm in the network planning algorithm information correspondingly needs to be changed to a BSIC (GSM), scrambling code (CDMA, UMTS, UMB, LTE) planning algorithm.

 In addition, for the LTE system, it is not necessary to perform the neighboring cell planning operation; for the GSM, CDMA, UMTS, UMB, and LTE systems, the frequency of use can be obtained in addition to the above method, and the frequency of the frequency can be directly applied to the core network. It is not necessary to perform the steps of scanning and selecting frequency points.

 The wireless network planning method in the embodiment of the present invention enables the base station to automatically perform wireless network planning according to the network planning algorithm information acquired from the core network, thereby eliminating a large number of manual operations and effectively reducing the working cost of the wireless network planning. Moreover, through the automatic network planning of the base station, configuration parameters optimized according to the actual environment can be obtained, so that the base station can realize real-time and optimized automatic configuration.
