Description

Neighboring cell configuration method and device, home base station configuration method and device

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for configuring a neighboring cell, and a method and device for configuring a home base station.

Background technique

With the wide application of the third-generation mobile communication system (3G), the number of users continues to increase, and the business volume increases month by month. Driven by the rapid growth of business, the network ushers in a high-speed growth demand. Therefore, the network capacity, coverage and Higher requirements are put forward for the quality. Judging from the existing actual 3G network coverage, indoor coverage is the weak link of 3G, especially in places where the coverage is poor.

Femtocell base stations (femtocells), also known as home base stations, are characterized by small size, low power, and plug-and-play. Since home base stations are mainly for personal consumption, the number is huge, and they need to be maintenance-free, or require as few operators as possible In terms of maintenance and technology (in terms of access), it is necessary for the femtocell to support fully automatic configuration of data, automatic detection and control of interference, automatic clock synchronization, and automatic planning and optimization.

Among the automatic planning and optimization functions of the femtocell, the automatic neighbor cell planning is the core function. In the implementation process, the femtocell automatically detects the information of the macro cell in the surrounding environment through a receiver, and configures it as its own neighbor cell. Whether the neighbor cell is correct or not directly determines the handover performance of the network composed of femtocells. Due to the limitation of the installation location of the femtocell, its detectable range is not exactly the same as the coverage range, and it may happen that the macro cell required for handover cannot be detected, resulting in call drop.

The current neighbor cell configuration method based on the Femtocell receiver usually uses tools to manually configure parameters for each Femtocell.

However, in the process of implementing the above technical solution, the inventor found that the above technical solution has certain defects. The number of home base stations is huge, and the installation location cannot be controlled in advance. Manually configuring parameters for each home base station is very difficult for home base stations.

Detailed ways

The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

As shown in Figure 1, it is a flowchart of an embodiment of a method for configuring a neighboring cell of the present invention, the method includes:

Step 101, acquiring at least one macro cell;

The home base station uses a receiver to detect wireless signals, and demodulates at least one macro cell;

Step 102, acquiring the neighbor cell information of the above at least one macro cell;

Among them, there are many ways to obtain the neighbor cell information. For example, it can be obtained by analyzing the system information of the above-mentioned macro cell, which specifically includes analyzing the system information 11 of the macro cell by the home base station to obtain the measurement control information element (Measurement control system information) , and then analyze the same-frequency measurement system message and the different-frequency measurement system message in the measurement control information element, and correspondingly obtain the same-frequency adjacent cell information of the macro cell and the different-frequency adjacent cell information of the macro cell, the above-mentioned same-frequency adjacent cell information of the macro cell Adjacent cell information and inter-frequency adjacent cell information of the macro cell are the adjacent cell information of the macro cell; in addition, the adjacent cell information of the macro cell can also be obtained by querying the above-mentioned macro cell base station database or by selecting adjacent cells through planning tools ;

Step 103, performing neighbor cell configuration according to the above at least one macro cell information and neighbor cell information;

The home base station generates a neighbor cell configuration list according to the at least one macro cell information and the neighbor cell information, and performs neighbor cell configuration according to the neighbor cell configuration list, wherein the generated neighbor cell configuration list can be stored in the home base station;

Step 104, optimize the above neighboring cell information, and configure neighboring cells according to the optimized neighboring cell information.

It should be noted that this step is an optional step, and there may be many adjacent cells of the home base station obtained according to the above steps 101 to 103. Since the coverage of the home base station is limited, the number of neighboring cells that actually affect the home base station is also limited. , therefore, in order to make the neighbor cell configuration more reasonable and accurate, when the neighbor cell information of the home base station is greater than a predetermined threshold, the above neighbor cell information can be optimized, and the neighbor cell can be configured according to the optimized neighbor cell information. Of course, the above The predetermined threshold can be set as required.

The above neighbor cell configuration method can not only configure the detected macro cell as the neighbor cell of the home base station, but also configure the detected neighbor cell of the macro cell as the neighbor cell of the home base station, so that a comprehensive and complete home base station can be obtained Neighboring cell information realizes the automatic configuration of the home base station, thereby avoiding handover call drop and improving the handover success rate; at the same time, the automatic configuration of the home base station by optimizing the neighboring cell information effectively improves the handover efficiency; and the above method is simple to implement .

The home base station has a downlink receiving function, and can use a dedicated receiving channel to complete wireless environment scanning; in addition, because the home base station has a receiving function similar to that of a mobile phone, the home base station can also be transformed into a "UE" working mode, so that the home base station can be used like a mobile phone. The "UE" works the same, and the frequency of the transceiver channel is the same as that of the UE; the wireless environment scan is completed, and the strongest macro cell N_detect corresponding to the strongest signal is detected;

Step 202, analyzing the system message SIB11 of the strongest macro cell;

Analyze the SIB11 of the above-mentioned strongest macro cell N_detect to obtain the "measurement control cell";

Step 203, analyze the "intra-frequency measurement system message" to obtain {Ns_intra_macro};

Analyze the "intra-frequency measurement system information (Intra-frequency measurement system information)" and "inter-frequency measurement system information (Inter-frequency measurement system information)" in the measurement control information element to obtain "intra-frequency cell info list" respectively " and inter-frequency cell info list (Inter-frequency cell info list) }, where {Ns_intra_macro} is the set of intra-frequency adjacent cells of the strongest detected macro cell;

Step 204, analyze the "inter-frequency measurement system message" to obtain {Np_inter_macro};

This step is a parallel step with step 203, parsing "inter-frequency cell info list" to obtain "inter-frequency cell id" and {Np_inter_macro}, {Np_inter_macro} is detected A collection of inter-frequency adjacent cells of the strongest macro cell;

Step 205, generate a complete neighbor list according to {Ns_intra_macro} and {Np_inter_macro}.

The home base station generates a complete neighbor cell configuration list {N_femto}={Ns_intra_macro}+{Np_inter_macro}+N_detect.

The above-mentioned process of obtaining the neighboring cell information is prepared for the automatic configuration of the Femtocell by obtaining the complete information of the neighboring cells of the HNB, thereby avoiding handover call drop and improving the handover success rate.

The conditions for the above neighbor cell optimization may include different parameters according to different scenarios and different requirements, for example, may include the optimization duration T and the number of handovers N;

Step 302, collecting the target cell contained in the relocation message used for handover;

The relocation message used for the above handover contains the target cell determined for each handover, and the cell used during the handover is recorded in the neighbor cell list;

Step 303, generating a list of target cells;

The home base station collects the measurement reports reported by the UE, collects the target cells that have been handed over within a specified time, and generates a list of target cells.

Step 304, calculating the switching times M;

Accumulate the number of handover times of the terminal UE within the specified time to calculate the total number of handovers M;

Step 305, judging whether the time T1 for collecting the target cell reaches the optimal duration T, if so, execute step 306, otherwise turn to step 302;
