detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The first network of the embodiment of the present invention includes an FDD network, and the second network includes a TDD network. The application scenario of the embodiment of the present invention is, for example, an FDD/TDD fusion networking, and a preset fusion group. The network strategy is, for example, FDD to form a basic overlay network; TDD meets hotspot coverage and key coverage; FDD satisfies most of the telecommunication services, while TDD uses its complementary spectrum and uplink and downlink time slot switching configurability and reciprocity to satisfy the enhancement. Telecommunications business needs, especially for mobile Internet.

FIG. 1 is a flowchart of Embodiment 1 of a method for configuring a convergence network according to the present invention. As shown in FIG. 1 , the method for configuring a convergence network in this embodiment may include:

101. Acquire at least one enhanced coverage area in the first network, and the enhanced coverage area is a coverage area where the signal quality does not meet the signal quality target.

The signal quality targets of the coverage areas and the coverage areas of the first network may be preset according to the networking policy, and the signal quality of each coverage area may be obtained by network simulation or road test. Here, the signal quality can adopt various indicators, for example, the signal-to-noise ratio, the signal-to-noise ratio, the power of the signal, and the like, which are not limited in the embodiment of the present invention. If the signal quality of the coverage area does not satisfy the signal quality target of the coverage area, the area is an enhanced coverage area.

It is assumed that the network is covered by the first network in the embodiment, and the second network is an enhanced coverage network for covering the hotspot coverage area and/or the key coverage area; wherein the hotspot coverage area refers to the presence in a specific area. A large number of business requests, the key coverage area refers to the high quality of service requirements in a specific area, and its business volume may be small. For example, FDD sets up a basic coverage network; TDD satisfies hotspot coverage area coverage and key coverage area coverage; FDD satisfies most of the telecommunication services, while TDD forms a basic coverage network with respect to FDD spectrum, and uses TDD-added spectrum, uplink and downlink time slots. Switching configurability and uplink and downlink channel reciprocity to meet the needs of enhanced telecommunication services, especially mobile Internet services.

The hotspot coverage area or the key coverage area has high utilization rate of power resources and frequency resources, or the average user throughput is low, or the network resources cannot meet the user requirements, and often fail to achieve the expected signal quality target and affect the user experience. If the signal quality does not satisfy the signal quality target of the coverage area in these coverage areas, these areas can be used as enhanced coverage areas.

102. Determine, according to the at least one enhanced coverage area, an area covered by the site of the second network and the site co-site of the first network.

Determining, according to the number of at least one enhanced coverage area, the location of the distribution, etc., whether the area covered by the site of the second network and the site co-site of the first network is in the entire network coverage area of the first network, or only in these enhanced coverage region.

For example, when the number of enhanced coverage areas is small and the locations of the distributions are relatively dispersed, the sites of the second network and the sites of the first network may be used to cover only the sites in the enhanced coverage areas; for example, the number of coverage areas is enhanced. More and more, the location of the distribution is continuous, and the site of the second network may be used in the network coverage area of the first network and the site of the first network to be shared by the site. The embodiment of the present invention is not limited thereto.

The site-to-site coverage of the site of the second network and the site of the first network includes: the site of the second network and the site of the first network are deployed at the same site location, and the coverage is the same, or the site of the second network and The sites of the first network are deployed at the same site location, and the site coverage of the second network is smaller than the site coverage of the first network. When the site of the second network overlaps with the site of the first network in the coverage area of the entire network of the first network, the number of sites of the second network is the same as the number of sites of the first network, and the sites of the first network are Deployed at the same site location, this situation can also be referred to as network-wide co-site coverage; when the site of the second network overlaps with the site of the first network in at least one enhanced coverage area, each enhanced coverage The number of sites of the second network in the area is the same as the number of sites of the first network, and the sites of the first network are deployed at the same site location. This situation may also be referred to as clustered co-site coverage.

2 is a schematic diagram of a FDD/TDD fusion networking mode in the first embodiment of the method for configuring a convergence network according to the present invention. As shown in FIG. 2, the FDD (equivalent to the first network) resource of the entire network area is limited, such as the first network. The lack of spectrum resources and low signal strength, and the inability to adjust the existing network to meet the needs of users, requires TDD (equivalent to the second network) spectrum for network-wide co-site coverage supplement.

For another example, the enhanced coverage area is fragmented discontinuous throughout the network area and may be covered by clustered co-sites. Among them, the clustered common site coverage includes isolated co-site coverage, (such as TDD isolated co-site coverage) single-cluster co-site coverage, or multi-cluster co-site coverage; isolated co-site coverage refers to each cluster only A base station, wherein the cluster refers to an enhanced coverage area; the single-cluster co-site coverage refers to an enhanced coverage area included in the entire network area, and the multiple coverage areas jointly cover the enhanced coverage area, and the multi-cluster common site coverage is Refers to multiple enhanced coverage areas across the network.

For the sites of the first network and the sites of the second network deployed at the same site location, the coverage of the two networks is the same, which may be referred to as common coverage, or the site coverage of the second network is smaller than the site coverage of the first network. It can be called concentric circle coverage.

When the site of the second network and the site of the first network are deployed at the same site location, and the second network When the coverage of the network site is smaller than the coverage of the site of the first network, the site of the second network may be used to cover the inner circle sector. In this case, the inner circle sector may adopt a directional antenna multi-sector networking manner, or An omnidirectional sector networking consisting of omnidirectional antennas, or an omnidirectional sector networking consisting of directional antennas.

FIG. 3 is a schematic diagram of a sector coverage relationship of an FDD/TDD fusion networking in the first embodiment of the method for configuring a converged network according to the present invention, as shown in FIG. 3: coverage of a TDD site and an FDD site in an FDD/TDD co-site relationship The relationship is shown in Figure 3. It can be either a common coverage or a concentric circle coverage. The so-called common coverage is the same coverage of the FDD site and the TDD site under the same site, and the concentric circle coverage is the coverage of the TDD site under the same site. The range is smaller than the coverage of the FDD site. Co-covering also means that continuous TDD site coverage is continuous. Concentric circle coverage means that continuous TDD site coverage is discontinuous. Discontinuous TDD site coverage means that adjacent TDD base stations can be configured with different time slot switching points. It does not cause TDD's unique Cross Talk.

Among them, in the FDD/TDD concentric circle coverage relationship, the TDD site covers the inner circle of the sector, and the inner circle sector can adopt the directional antenna multi-sector networking mode, or an omnidirectional fan composed of an omnidirectional antenna or a directional antenna. The way the network is organized.

The method for configuring the fused network provided by the embodiment of the present invention, after the network is covered by the first network, and the second network is the hotspot coverage and the key coverage network, obtain at least one enhanced coverage area in the first network, according to the enhancement. The signal quality target of the coverage area and the enhanced coverage area determines the area covered by the site of the second network and the site co-site of the first network according to the at least one enhanced coverage area, for example, the spectrum resources of the first network are restricted in the entire network area In the case that the second network can be supplemented in the entire network area; or the second network can be supplemented in the enhanced coverage area of the first network; therefore, the embodiment can freely form the fusion group of the first network and the second network. The network mode enables the second network to effectively supplement multiple hotspots or key coverage areas of the first network, thereby improving the overall network user experience of the first network.

On the basis of the foregoing embodiment, optionally, after step 102, the method may further include:

103. Configure an uplink and downlink time slot switching relationship of a site of the second network.

4 is a schematic diagram of TDD uplink and downlink time slot switching configuration in the second embodiment of the method for configuring a fused network according to the present invention. In FIG. 4, the FDD/TDD fused network mode is FDD full network coverage, and the TDD multi-cluster common site coverage is For example, as shown in FIG. 4, the specific configuration manner may include at least one of the following:

Configuring different time slot switching points for sites of the second network between different enhanced coverage areas, or Different time slot switching points are configured between sites of the second network that are not continuously covered in the same enhanced coverage area, which is usually caused by the concentric circle coverage of the site of the second network and the site of the first network. The site coverage of the two networks is discontinuous; or the same slot switch point is configured between the sites of the second network that are continuously covered in the same enhanced coverage area. Therefore, the use of clustered co-site coverage can increase the flexibility of the uplink and downlink time slot ratio.

Optionally, after step 103, the method may further include:

104. Determine an antenna mode of each site covered by the site of the second network and the site co-site of the first network.

The antenna mode includes a site of the first network and a site of the second network share a physical antenna mode, or a site of the first network and a site of the second network have independent physical antenna modes. When the site of the first network and the site of the second network share a pair of physical antenna modes, the limitation of the space space can be minimized.

Wherein, when the site of the first network and the site of the second network share a physical antenna mode, the site of the first network and the site of the second network use different physical ports of the same physical antenna, the site of the first network and the first The antenna downtilt of the site configuration of the two networks is independently adjusted.

Specifically, determining an antenna mode of each site covered by the site of the second network and the site co-site address of the first network may include:

The radio frequency parameters of the stations of each of the second networks are configured, and the radio frequency parameters include at least one of an antenna azimuth, an antenna tilt angle, an antenna broadcast beam weight, or a power. The radio frequency parameter of the site where each second network is configured may be configured according to a reference value or a manual experience value provided by the network specification software. The radio frequency parameter is the basis for constructing a relative coverage relationship in the converged networking mode of the first network and the second network. In the common coverage relationship, the first network and the second network have the same or similar downtilt settings and are compared. The power setting, in the concentric circle coverage relationship, the downtilt angle of the second network is greater than the downtilt angle of the first network, or the power of the second network configuration is less than the power of the first network configuration.

For example, the site of the first network may be configured in a 2T4R antenna configuration mode, wherein the 2T4R antenna configuration mode includes 4 antennas, and 2 of the 4 antennas are both a transmitting antenna and a receiving antenna, and the other 2 of the 4 receiving antennas The antennas are receiving antennas; the stations of the second network can be configured in a 2T2R antenna configuration mode, wherein the 2T2R antenna configuration mode includes 2 antennas, and the 2 antennas are both a transmitting antenna and a receiving antenna. It should be noted that the embodiments herein are merely examples, and the embodiments of the present invention are not limited thereto.

When the site of the first network and the site of the second network have independent physical antenna modes, the antenna downtilt of the site of the first network and the site configuration of the second network are independently adjusted. At this time, the site of the first network can be configured as a 2T4R antenna configuration mode, and the site of the second network can be configured as an 8T8R antenna configuration mode, wherein the 8T8R antenna configuration mode includes 8 antennas, and 8 antennas are both a transmitting antenna and a receiving antenna. .

FIG. 5 is a schematic diagram of an antenna pattern of a site in an FDD/TDD fusion networking mode according to Embodiment 3 of the method for configuring a convergence network according to the present invention. As shown in FIG. 5, the antenna mode is generally divided into an FDD site and a TDD site. There are two types of physical antenna mode and independent physical antenna mode. The left side of Figure 5 is a shared physical antenna mode. In this mode, the FDD site and the TDD site can use different physical ports in one antenna. In the figure, the FDD site can be configured in 2T4R mode, and the TDD site can be configured into 2T2R mode. , FDD / TDD can independently adjust the downtilt angle. The right side of Figure 5 is the independent physical antenna mode. The FDD station supports 2T4R mode. The TDD station supports 8T8R mode. The 8T8R TDD site will ensure better edge rate capability. FDD/TDD can also adjust the downtilt angle independently. 6 is a schematic diagram of adjusting the downtilt angle of the FDD/TDD common site used in the embodiment of the present invention. As shown in FIG. 6, the FDD/TDD can independently adjust the downtilt angle. FDD/TDD independently adjusts the tilt angle to facilitate independent optimization of the two networks.

The method of the embodiment of the present invention may be repeatedly performed repeatedly, so that the signals of the respective coverage areas in the first network gradually satisfy the signal quality targets of the corresponding coverage areas.

The technical solutions of the foregoing method embodiments are described in detail below by using three specific embodiments.

FIG. 7 is a schematic diagram of a networking diagram of Embodiment 4 of a method for configuring a converged network according to the present invention. As shown in FIG. 7 , the networking scenario in this embodiment is: FDD forming a basic network, TDD clustering common site, and an enhanced coverage target is Enhanced edge coverage, so the enhanced coverage area is the edge area, as follows:

Step 1. Obtain an edge region in the FDD.

Step 2: Determine an FDD/TDD fusion networking mode according to the obtained edge region. details as follows:

The basic network is set up by the FDD base station, and each station uses a three-sector mode network, and the inter-sector frequency reuse factor is 1, which constitutes continuous coverage of the entire area. The criterion for selecting the site of the TDD base station is that the TDD base station is deployed in an isolated co-site manner, and the built TDD site is co-located with the FDD site. For example, if the station ratio is 1/4 of the FDD base station, the TDD base station adopts the method of selecting the station, that is, one FDD base station is included between every two TDD stations. Each TDD site uses a three-sector mode network.

Step 3: Determine, according to the result of the TDD base station site selection, the TDD base station belonging to the isolated sector cluster. Adjusting the uplink and downlink time slot switching points in each group of isolated TDD sector clusters according to the sector edge data rate indicator to be satisfied, and changing the uplink and downlink time slot ratios, such as 1:3, 2:2, 3:1, etc. To adjust the uplink and downlink bandwidth resources.

Step 4. According to whether the space in the sky space is limited and the sector capacity index, select the appropriate antenna type. Limited space in the sky means that there is limited space on the tower or pole that is used to hang the antenna. If it is not possible to accommodate the FDD and TDD independent antennas at the same time, the shared physical antenna method can be used. The TDD and TDD base stations use different ports of the antenna. If the space is not limited, both independent antennas and shared antennas can be used.

Step 5: The FDD transceiver channel adopts the 2T4R mode to ensure the average data rate of the sector. The TDD transceiver channel adopts the 8T8R mode to improve the edge data rate and reduce the interference to the neighboring area. If FDD and TDD use a shared physical antenna, the antenna is required to have an independent electrical modulation mode. The FDD antenna adopts a large downtilt angle to balance the data rate between the near end and the far end of the sector. The TDD antenna uses a small downtilt angle to enhance the edge. Data rate.

Step 6. Determine whether the network coverage, time slot switching, antenna, and radio frequency parameters meet the requirements for enhanced edge coverage by using network simulation or network initial deployment. If the return to step 2 is not satisfied, the closed loop control is performed.

FIG. 8 is a schematic diagram of a networking diagram of Embodiment 5 of a method for configuring a converged network according to the present invention. As shown in FIG. 8 , the networking scenario in this embodiment is: an FDD grouping basic network, and a TDD full network co-site address overlay. The enhanced coverage goal is to increase the capacity of each area of the entire network. Therefore, the enhanced coverage area is the entire area of the entire network. The specific process is as follows:

Step 1. Obtain all areas of the entire network in the FDD.

Step 2: Determine the FDD/TDD fusion networking mode according to the obtained areas of the entire network. details as follows:

The basic network is set up by the FDD base station, and each station uses a three-sector mode network, and the inter-sector frequency reuse factor is 1, which constitutes continuous coverage of the entire area. The entire network TDD base station and the FDD base station share the site coverage. Each site uses a three-sector networking approach. The TDD base station group builds a network covering the entire area.

Step 3: According to the sector edge data rate indicator to be satisfied, adjust the uplink and downlink time slot switching points in the TDD system in the entire network, and change the uplink and downlink time slot ratio, such as 1:3, 2:2, 3:1, and the like.

Step 4. According to whether the space in the sky space is limited and the sector capacity index, select the appropriate antenna type. Limited space in the sky means that there is limited space on the tower or pole that is used to hang the antenna. If it is not possible to accommodate FDD at the same time, The TDD independently erects the antenna, and the shared physical antenna method can be used. The TDD and TDD base stations use different ports of the antenna. If the space is not limited, both independent antennas and shared antennas can be used.

Step 5: The FDD transceiver channel adopts the 2T4R mode to ensure the sector average and the sector edge data rate. The TDD transceiver channel adopts the 2T2R mode to supplement the shortage of the FDD system in the spectrum resources. The FDD and TDD antennas use the same preset tilt angle.

Step 6: Determine whether the network coverage, the time slot switch, the antenna, and the radio frequency parameter meet the preset networking requirements by using network simulation or initial network deployment, and if not, return to step 2 for closed-loop control.

FIG. 9 is a schematic diagram of a networking diagram of Embodiment 6 of a method for configuring a converged network according to the present invention. As shown in FIG. 9 , the networking scenario in this embodiment is: FDD is set up to establish a basic network, and TDD is a total network site, and the enhanced coverage target is Increase the capacity of the central area of the sector, so the enhanced coverage area is the center area of the sector. The specific process is as follows:

Step 1. Obtain a sector center area in the FDD.

Step 2: Determine an FDD/TDD fusion networking mode according to the obtained sector center area. details as follows:

The basic network is set up by the FDD base station, and each station uses a three-sector mode network, and the inter-sector frequency reuse factor is 1, which constitutes continuous coverage of the entire area. The whole network TDD base station and the FDD base station share the site, but the TDD base station only covers the sector near end region. Each site uses a three-sector networking or an omni-directional sector networking.

Step 3: Determine, according to the result of the TDD base station site selection, the TDD base station belonging to the isolated sector cluster. Adjust the uplink and downlink time slot switching points in each group of isolated TDD sector clusters according to the sector center data rate indicators to be met (such as Vip users and user centralized distribution areas), and change the uplink and downlink time slot ratios, such as 1:3. 2:2, 3:1, etc.

Step 5: The FDD transceiver channel adopts the 2T4R mode to ensure the sector average and the sector edge data rate. The TDD transceiver channel adopts the 2T2R mode to improve the data in the central area of the sector.
