Embodiment
This invention describes a kind of method of cell networking, as shown in Figure 1, described method comprises:
Step 10: set up at least one antenna on multichannel RRU, and be the corresponding prevention at radio-frequency port of described at least one antenna assignment, described at least one antenna is connected with described prevention at radio-frequency port, and utilizes AISG standard cable by all antenna cascades on described RRU.
Wherein, described multichannel RRU can be multi-emitting passage RRU, can be specifically the RRU (referred to as 2N passage RRU) with 2N (N is positive integer) individual transmission channel; Described 2N passage RRU has 2N the prevention at radio-frequency port being numbered antenna hardware interface ANT (1) to ANT (2N); According to real network distribution situation, as the distance etc. between the coverage of current city communication network actual deployment situation, base station and base station, even or the corresponding prevention at radio-frequency port of grayscales uneven distribution gives the respective antenna in described at least two antennas, and the corresponding prevention at radio-frequency port by having distributed, carry out the physical connection of described 2N passage RRU and described at least two antennas; Afterwards, utilize antenna consensus standard group agreement (AISG, Antenna Interface Standards Group) standard cable that described at least two antennas are carried out cascade physically.Described antenna can be specially electrical tilt antenna.
Such as, when the radical of electrical tilt antenna is two (the first electrical tilt antenna and the second electrical tilt antenna) just, described 2N passage RRU is connected with described first electrical tilt antenna by common N number of prevention at radio-frequency port of numbering ANT (1) to ANT (N), is connected with described second electrical tilt antenna by common N number of prevention at radio-frequency port of numbering ANT (N+1) to ANT (2N); In addition, common N/2 the prevention at radio-frequency port that described 2N passage RRU can also pass through numbering ANT (1) to ANT (N/2) is connected with described first electrical tilt antenna, is connected with described second electrical tilt antenna by common 3N/2 the prevention at radio-frequency port of numbering ANT (N/2+1) to ANT (2N).
Step 11: by the base-band resource parameter in reprovision BBU, makes the current area of described RRU be split at least Liang Ge community.
Wherein, when realizing eNodeB communications network deployment, the operation that the base-band resource parameter be stored in described BBU is configured and all being undertaken by modes such as software or soft and hardware combine with the relevant operational that described base-band resource parameter is configured.Here, according to step 10 and the distribution of current city actual communication networks, the base-band resource parameter of current area is reconfigured as the base-band resource parameter needed for the community after division by the mode combined by software or soft and hardware; And according to described required base-band resource parameter, current area is split at least Liang Ge community.
Step 12: by regulating the inclination angle of each antenna of described RRU respectively, community after making the signal of each antenna of described RRU cover corresponding division respectively, when the overlapping region of the overlay area of every two neighbor cells after dividing exceeds predeterminable area threshold value, every two neighbor cells after described division are merged as a community;
Here, the handling process of described step 12 can regard the process that the overlay area of community after to division is optimized process as;
Further, current area is split at least Liang Ge community, and the neighbor cell of described current area is also split at least Liang Ge community; And regulated the inclination angle of the respective antenna of described current area and RRU corresponding to neighbor cell respectively by the mode that software or software and hardware combine, the community after making respective antenna cover corresponding division respectively;
Here, give an example, current area is split into the far a little community C1 of distance RRU closely a little community B1 and distance RRU, regulates first antenna of the RRU that community B1 is corresponding, and the community B1 making the first antenna adjust the distance closely a little realizes optimizing and covers; Regulate second antenna of the corresponding RRU of community C1, make the second antenna Yuan Xie community C1 that adjusts the distance realize optimizing and cover; So, while the signal strengthening the closely a little community of distance, also make the signal of a little community of distance be enhanced, thus improve cell capacity, all user terminals in each community (UE, User Equipment) are made all to have approximately uniform signal to noise ratio.
Preferably, when the overlapping region of the overlay area of every two neighbor cells after dividing exceedes the region threshold pre-set, the base-band resource parameter regulating every two neighbor cells after described division is identical, as the sequence of cells number (ID of every two neighbor cells as described in regulating, Identity), described every two neighbor cells carrier frequency, logical channel number, signaling channel number, the control channel number that use be identical, and every two neighbor cells after described division are merged as a community.
Here, the base-band resource parameter needed for community after the base-band resource parameter of current area, division is all consistent with the base-band resource parameter that stores in existing RRU, as community ID, as described in community use carrier frequency, as described in the parameter such as the logical channel number of community, signaling channel number, control channel number; The concrete involved parameter of described base-band resource parameter is too much, does not enumerate here; The base-band resource parameter needed for community after the described division such as the quantity of the community after described division is determined according to real network distribution situation.
Fig. 2 (a) is specific embodiment of the invention schematic diagram to 2 (c), all configure two electrical tilt antennas in conjunction with 2 (a) to 2 (c) with eNodeB1, eNodeB2, and 4 passage RRU (N=2) for example, the present invention is further illustrated.
In eNodeB1, described 4 passage RRU carry out physical connection by the prevention at radio-frequency port of numbering ANT (1) and ANT (2) and described first electrical tilt antenna, carry out physical connection by the prevention at radio-frequency port of numbering ANT (3) and ANT (4) and described second electrical tilt antenna; Described first electrical tilt antenna and the second electrical tilt antenna are carried out cascade physically by recycling AISG cable.According to real network distributions such as above-mentioned physical connection and current city communication network actual deployment situations, the base-band resource parameter of current area is reconfigured for the base-band resource parameter needed for the community after division by the mode combined by software or soft and hardware; Here, in advance the current area of ID=1 is divided, then the base-band resource parameter relevant with the current area of ID=1 stored in BBU is reconfigured, the quantity of the community after the division that current area Pre-splitter formed as reconfigured is 2, as described in the ID of community after division be respectively 11 and 12 etc., certainly the base-band resource parameter stored in base-band resource parameter described here and existing RRU is consistent, and does not enumerate the content that base-band resource parameter described here specifically comprises.
After the base-band resource parameter of the current area in eNodeB1 is reconfigured accordingly, current area is split into community B1 and community C1, as shown in Fig. 2 (a), the RRU of community B1 distance eNodeB1 more closely, the RRU of community C1 distance eNodeB1 far, regulate the inclination angle of described first electrical tilt antenna, make community B1 described in described first electrical tilt antenna quorum sensing inhibitor; Regulate the inclination angle of described second electrical tilt antenna, make community C1 described in described second electrical tilt antenna quorum sensing inhibitor, so, the signal of the community C1 that the community B1 just making distance RRU closely a little and distance RRU is far a little is all enhanced, thus improves cell capacity and network performance.
When carrying out above-mentioned process to the current area in eNodeB1, the neighbor cell being arranged in eNodeB2 also as above processes, described neighbor cell is split into community B2 and community C2, as shown in Fig. 2 (b), the RRU of community B2 distance eNodeB2 more closely, the RRU of community C2 distance eNodeB2 far, regulates the inclination angle of first electrical tilt antenna of eNodeB2, makes community B2 described in described first electrical tilt antenna quorum sensing inhibitor; Regulate the inclination angle of second electrical tilt antenna of eNodeB2, make community C2 described in described second electrical tilt antenna quorum sensing inhibitor; Like this, the signal of the community B2 that the community C2 that distance RRU is far a little and distance RRU is closely a little is all enhanced.
Because the overlay area of minizone has overlapping region, so when the overlapping region of the overlay area of two neighbor cell C1 after determining division and community C2 exceedes the region threshold pre-set, the base-band resource parameter regulating community C1 and community C2 is identical, described community C1 and community C2 is made to merge into same community C, namely form super cell C, so just enhance the coverage strength of former cell edge signal.Carrying out above-mentioned optimization to the community after division covers rear as shown in Fig. 2 (c).
Above-mentioned in the explanation of the technical program, region threshold is exceeded based on the overlay area of two neighbor cell C1 after division and community C2, and in actual applications, as long as when the overlapping region of the overlay area of every two neighbor cells after division exceedes described region threshold, all same community can be merged into; Annular or band shape super cell are merged in the every two or more neighbor cell so just making overlapping region exceed described region threshold.
