Description

Network resource configuration method and device

Technical field

Embodiments of the present invention relate to the field of mobile communication technology, and in particular, to a network resource configuration method and device.

Background technique

At present, in the communication network coverage of traffic trunk lines of mobile communication networks, highways still use public network coverage due to their relatively slow moving speed and small penetration loss; while high-speed rails are prone to switching chaos and For problems such as call failures and call drops, high-speed rail dedicated networks are generally used for network coverage. At the same time, in order to ensure that high-speed rail users can exclusively enjoy private network resources, the policy of not configuring neighbor cells for private/public networks came into being. That is, no public network neighbor cells are added to the private network, even during reselection and switching neighbor cell operations. no added. As the current mileage of high-speed railways and expressways continues to grow, there are more scenarios in which high-speed railways and expressways can run side by side or cross. At this time, the traditional strategy of not adding public network adjacent areas can avoid users (terminals) in the connected state from being Movement (i.e., handover) behavior between the private network and the public network can also prevent idle users from entering another network through the reselection mechanism. However, since the signal strength of the high-speed rail private network is much better than that of the public network, it is unavoidable for users on the public network to enter the private network through cell selection/power-on attachment and other behaviors in the idle state.

When users leave the coverage area of the high-speed rail private network, they will be unable to switch to the public network because there is no adjacent area. Under the current situation where the Time Division (TD) network has been shut down, the user will be redirected to the 2G network. However, mobile communication networks currently do not support terminals returning to 4G in the 2G connected state. Therefore, users cannot return to 4G before 2G enters the idle state, resulting in the phenomenon of "no 4G network" and seriously affecting user perception.

In order to solve this problem, there are usually two solutions in the existing technology:

1. High-speed rail and expressway alone cover:

Through accurate planning and construction of sites, fine adjustment of antennas and other methods to control basic coverage, private network sites covering high-speed rail and public network sites covering expressways are separated, so that there is no cross-over or overlapping coverage between the two, and avoid high-speed users The situation of occupying the high-speed rail private network signal.

However, in this method, the coverage edge of the base station cannot be accurately controlled. For high-speed rail and high-speed parallel scenarios, it is difficult to avoid overlapping coverage between the two networks; and as long as there is overlapping coverage, the terminal can detect the two network signals at the same time. Private/public networks do not configure neighbor cell policies. Although it can prevent users in the connected state from moving between private/public networks, and it can also prevent users in the idle state from entering another network through the reselection mechanism, it cannot be avoided. Public network users enter the private network in idle mode.

2. Add neighboring cells to realize switching between private network and public network:

For the special scenario where high-speed railways and expressways "run in parallel first and then branch off", a one-way neighbor relationship between the private network and the public network can be added, and at the same time, with the precise adjustment of parameters such as the detection threshold, it is possible to move the train out of the coverage of the high-speed railway of high-speed users access the public network. Neighboring cell measurement is the prerequisite for terminals to complete handover. For the special scenario of high-speed rail and expressway "running in parallel first and then bifurcating", if adjacent cells to the public network are added, it can ensure that high-speed users leave the private network coverage when they leave. Switching back to the public network smoothly, but at the same time, it is easy for high-speed rail users to leave the private network and switch to the public network; the coverage strength of the public network is far less than that of the private network, coupled with the high speed of high-speed rail and the rapid fading in the carriage, it is difficult for high-speed rail users to use the public network. The business perception experience will be greatly reduced.

In summary, the two existing solutions are difficult to achieve precise control, and the adjustments made cannot only take effect on high-speed users. They cannot avoid causing high-speed rail users to leave the private network, which will have a greater impact on high-speed rail users’ 4G service perception.

Figure 1 shows a schematic flowchart of a network resource configuration method provided by an embodiment of the present invention.

As shown in Figure 1, a network resource configuration method provided by an embodiment of the present invention specifically includes the following steps:

Step 101: Obtain the mobile parameter data of the terminal in the target area within the preset statistical period; wherein the target area is the overlapping coverage area of the preset private network and the preset public network.

The target area is the overlapping coverage area of the default private network and the default public network, that is, the area is covered by both the default private network and the default public network.

The default private network can be a high-speed rail private network or other communication private network, and the default public network can be a high-speed public network or other ordinary public networks. As a first example, as shown in Figure 2, the solid line in Figure 2 represents a highway and the dotted line represents a high-speed rail line; if there are both highways and high-speed rail lines in Figure 2, this area is a target area. The movement parameter data of the terminal may be the terminal's movement speed, movement direction, etc., or the terminal's acceleration data. Within a preset statistical period, obtain the movement parameter data of all terminals in the target area within the statistical period.

Step 102: Determine a transition cell according to the movement parameter data; wherein the transition cell is a preset geographical range where key points of the terminal's movement trend are located.

Among them, the key point of the movement trend can be the position point where the terminal acceleration changes beyond the preset ratio, such as the movement direction changes, or the movement speed changes, and the amplitude of the change exceeds the preset amplitude, then the position can be determined points are key points. Take the overlapping coverage of high-speed and high-speed rail as an example. When the moving direction changes or the moving speed changes, for high-speed users, it is likely that the high-speed user side leaves the private network coverage and switches back to the public network. This position is the high-speed The location is separated from the high-speed rail, that is, the default private network is separated from the default public network. High-speed rail users (i.e., high-speed rail private network users) at this location can easily leave the default private network.

It can be understood that the determination of key points is based on the form of big data, that is, the terminal movement parameter data within the statistical period. Due to the large number of statistics, the specific location of the key points of each terminal may have a certain deviation. Therefore, it can be Set a geographical range. For example, if the key points of two terminals are within a preset distance, the two key points can be identified as one key point. Therefore, for multiple key points that meet the preset distance, statistics can be used Determine a key point that is the shortest total distance from all key points in the form of A community transitioning to the default public network.

Step 103: Determine the spectrum resources of the preset private network in the geographical location of the transition cell.

Among them, after the transition cell is determined, the spectrum resources of the preset private network at the location of the transition cell are determined according to the geographical location of the transition cell, so as to determine the spectrum resources of the transition cell based on the spectrum resources of the preset private network; optionally, Spectrum resources can include frequency bands, center frequency point numbers, etc.

As a second example, Table 1 below shows the spectrum resource content of the preset private network (high-speed rail private network) and the preset public network in the geographical location of the transition cell:

Table 1:

In Table 1, the high-speed rail private network as the default private network and the high-speed public network as the default public network respectively use different frequency bands, center frequency point numbers, and single carrier bandwidths.

Step 104: According to the spectrum resources, configure the transition cell as a co-frequency neighbor cell of the source cell of the preset private network in the geographical location.

Among them, as a third example, as shown in Figure 3, taking the high-speed rail private network as an example, due to the high speed of high-speed rail, in order to reduce the risks caused by handover operations, the high-speed rail private network generally adopts the strategy of merging multiple cells, that is, one source Multiple remote devices are connected, as shown in Cell A and Cell B in the figure. Multiple remote devices are connected to each cell; therefore, the same base station signal is covered within 2-3 kilometers along the high-speed railway. Users do not need to switch when moving during this period; at the same time, because the high-speed rail track is narrow, the high-speed rail private network uses high-gain narrow-beam antennas to enhance the coverage in the carriage.

If the high-speed rail private network near the transitional cell geographically belongs to two different source cells, high-speed users may occupy any one of the cells to leave the expressway. Therefore, both source cells need to add reselection and measurement frequency for the public network. point, then, within the 6 kilometers corresponding to the two source cells, high-speed rail users may also leave the high-speed rail private network and enter the public network, which cannot be completely avoided; therefore, when setting the frequency of the transition cell, it is not necessary to set the current The frequency of the public network is set to the frequency of the transition cell.

Considering that current 4G terminals need to perform co-frequency measurements at any time, and the network side cannot control the co-frequency measurement behavior, if the co-frequency strategy with the high-speed rail private network is adopted, the network parameters do not need to be adjusted. In addition, after setting the frequency of the transitional cell to the same frequency as the high-speed rail private network, the high-speed rail private network does not need to enable inter-frequency measurement for the preset public network, which can prevent high-speed rail users from measuring surrounding public networks and reduce the risk of high-speed rail users leaving the high-speed rail private network. risk. Therefore, when setting the frequency of the transition cell, the spectrum resources of the high-speed rail private network currently corresponding to the transition cell can be obtained, and based on the obtained spectrum resources, the transition cell is configured as the preset private network in the geographical location. The same-frequency neighboring cell of the source cell, that is, the transition cell is set to a cell with the same frequency as the high-speed rail private network.

It should be noted that when setting the frequency of the transitional cell to be on the same frequency as the high-speed rail private network, in order to avoid the antenna of the transitional cell causing co-frequency interference to the high-speed rail private network, it is also necessary to set the antenna of the transitional cell so that the coverage direction is away from the railway and The orientation is perpendicular to the direction of travel of the high-speed rail, and the front-to-back ratio of the antenna complies with specifications.

In the above embodiments of the present invention, the movement parameter data of the terminal in the target area within the preset statistical period is obtained; the transition cell is determined based on the movement parameter data; wherein the transition cell is the key to the movement trend of the terminal The preset geographical range where the point is located; determine the spectrum resources of the preset private network in the geographical location of the transition cell; configure the transition cell according to the spectrum resources to the preset private network in the geographical location. The same-frequency neighboring cells of the source cell eliminate the need for the high-speed rail private network to enable inter-frequency measurement for the preset public network, preventing high-speed rail users from measuring surrounding public networks and reducing the risk of high-speed rail users leaving the high-speed rail private network; and the adjacent cell configuration operation is simple and It is accurate and can play a guiding role in transitional cells when there are no coverage holes or weak coverage; and by configuring transitional cells as co-frequency neighboring cells, co-channel interference is avoided and the convenience of co-frequency switching can be achieved. Embodiments of the present invention solve the problem in the prior art that high-speed rail private network users easily leave the private network in a scenario where high-speed rail private networks and high-speed public networks coexist.

Optionally, in this embodiment of the present invention, the step of determining a transition cell based on the mobility parameter data includes:

The first step is to determine key points of the terminal's movement trend based on the movement parameter data; wherein the key points are the location points where a preset change occurs in the terminal's movement trend exceeding a preset proportion.

Among them, the key point of the movement trend can be the position point where the terminal acceleration changes beyond the preset ratio, such as the movement direction changes, or the movement speed changes, and the amplitude of the change exceeds the preset amplitude, then the position can be determined points are key points.

Specifically, the preset change is that the acceleration of the terminal of the preset private network at the key point remains unchanged, and the acceleration of the terminal of the preset public network at the key point changes. Meet the preset change requirements. For example, the traveling speed of most high-speed users (high-speed public network users) in this geographical location will change, while the traveling speed of most high-speed rail private network users in this geographical location will not change. , then this position is the position when the high-speed user side leaves the private network coverage and switches back to the public network, that is, the position where the high-speed and the high-speed rail are separated, that is, the position where the default private network and the default public network are separated. High-speed rail users are easy to leave at this position. Default private network.

The second step is to determine whether the preset geographical range where the key point is located meets the preset requirements.

In this step, after the key point is determined, a preset geographical range is defined with the key point as the center. The preset geographical range can be a circular range with the key point as the center and a preset radius as the radius.

After determining the preset geographical range, determine whether the preset geographical range meets the preset requirements; specifically, the step of determining whether the preset geographical range where the key point is located meets the preset requirements includes:

Determine whether the preset geographical range is a non-weak coverage cell, and whether the straight-line distance between the preset geographical range and the preset building meets the preset distance requirement.

Among them, when determining whether there is weak coverage within the preset geographical range, it can be determined based on the base station coverage around the geographical location. The base station coverage is determined based on pre-recorded records. Taking the preset building as a railway as an example, in When determining whether the distance to the preset building meets the distance requirements, you can first determine the straight-line distance between the geographical location and the nearest railway, and determine whether the straight-line distance is within the preset distance range. If it is within the preset distance Within the range, it can be determined that the distance between the geographical location and the nearest railway is moderate, neither very close nor very far away. At this time, it can be determined that the distance between the geographical location and the railway meets the preset distance requirement.

In the third step, if the preset geographical range where the key point is located meets the preset requirements, the preset geographical range is determined to be a transitional cell.

Among them, if there is no weak coverage phenomenon in the preset geographical range and the distance to the railway meets the preset distance requirements, the preset geographical range can be determined as the geographical location of the transitional community.

Optionally, in this embodiment of the present invention, the step of determining the spectrum resources of the preset private network in the geographical location of the transition cell includes:

According to the geographical location of the transition cell, spectrum resources of the preset private network in the geographical location are determined.

Among them, after determining the geographical location of the transition cell, determine the spectrum resources of the preset private network at the geographical location of the transition cell according to the geographical location of the transition cell, so as to determine the spectrum resources of the transition cell based on the spectrum resources of the preset private network.

Optionally, in the embodiment of the present invention, after the step of configuring the transition cell as a co-frequency neighbor cell of the source cell of the preset private network in the geographical location according to the spectrum resources, the The above methods also include:

Determine the target center frequency point of the spectrum resource;

The central frequency point of the transition cell is configured as the target central frequency point.

Among them, the center frequency point of the transition cell is configured as the target center frequency point. Refer to the above Table 1. The high-speed railway private network usually adopts D2+D3 double-layer networking. High-speed users may occupy any one when leaving the transition cell. Frequency. Therefore, the transition cell also needs to be configured with two frequencies, D2 and D3, so that high-speed users can rely on the transition cell to switch to the public network and avoid 4G mobile phones being disconnected from the network.

Specifically, the handover between the private network and the transition cell configures neighbor cells on the same frequency, and the handover between the transition cell and the public network configures all neighbor cells (that is, adding same-frequency or inter-frequency neighbor cells according to the frequency of the public network); the transition cell is used Guide two types of users to smoothly enter the public network: First, high-speed users who drive away from the highway. Because they drive a long distance on the highway parallel to the high-speed rail, although there is no adjacent area between the private network and the public network, they will pass through the residential area. Behaviors such as selecting/powering on and attaching occupy the high-speed rail private network; second, permanent residents near the transitional community will also occupy the high-speed rail private network because they are close to the high-speed rail and the signal of the high-speed rail private network is strong enough. When these two types of users leave the railway, they may occupy the high-speed rail private network signal. In the embodiment of the present invention, by configuring the center frequency point of the transition cell as the target center frequency point, these two types of users are guided to switch to the public network through the transition cell to avoid the situation where the 4G mobile phone is disconnected from the network.

Optionally, in the embodiment of the present invention, after the step of configuring the transition cell as a co-frequency neighbor cell of the source cell of the preset private network in the geographical location according to the spectrum resources, the The methods include:

Determine the average moving speed of the terminal at a preset sampling time;

Determine the target base station type corresponding to the average moving speed according to the preset corresponding relationship between the moving speed and the base station type; wherein, in the preset corresponding relationship, different moving speeds correspond to different base station types;

The base station of the transition cell is configured according to the target base station type.

Among them, the base station type of the transition cell can be a micro station (small base station), a macro station, a high-gain antenna, etc. The target base station type corresponding to the average moving speed can be determined according to the average moving speed, and a base station of the target base station type can be selected, so that It acts as a transitional community.

Specifically, the selection criteria depends on the user's moving speed when the user leaves the coverage area of the private network. If the moving speed is low, a micro station is selected, and if the moving speed is high, a high-gain antenna is selected. Although the coverage distance of the micro station is relatively close, the user will When leaving the expressway, the vehicle speed is low and can enter the public network under the guidance of the transition community. When the user leaves the coverage area of the high-speed rail private network and the vehicle speed is high, if a micro station is used as a transitional community, it cannot ensure that the user can enter the transitional community in time due to its small coverage area. Therefore, in such scenarios, high-gain antennas need to be used to serve as transition cells to ensure that users can successfully switch to the transition cell even when driving at high speeds.

It can be understood that the applicable scope of the embodiments of the present invention is mainly scenarios that meet the following three conditions: (1) high-speed rails run side by side at high speeds and are close to each other; (2) high-speed rails are built with private network coverage, and the high-speed rails are covered by ordinary buses. network coverage, and there is no neighbor relationship between the two; (3) After the high-speed rail runs side by side for a certain distance, the high-speed users leave the coverage of the high-speed rail private network. Through a preset number of field tests and network management indicator display, after executing the solution of the embodiment of the present invention, the number of one-way handovers and the handover success rate between the private network and the transitional cell and the transitional cell and the public network are normal.

And during the on-site test, the road test equipment needs to be placed under the far end of the high-speed rail to ensure that the road test equipment occupies the private network signal and starts to move away from the railway, simulating the user's movement route after leaving the expressway, and establishing a private network 300 meters away from the railway. The signal began to weaken, but after moving to the coverage area of the transitional cell, the mobile phone successfully switched into the transitional cell and then connected to the public network, effectively avoiding the problem of 4G mobile phone disconnection.

In terms of network management key indicators (KPI), there are an average of 224 handovers per hour between the private network and the transitional cell, with a success rate of over 99.4%; and an average of 241 handovers between the transitional cell and the public network per hour, with a success rate over 99.5%.

In the above embodiments of the present invention, the movement parameter data of the terminal in the target area within the preset statistical period is obtained; the transition cell is determined based on the movement parameter data; wherein the transition cell is the key to the movement trend of the terminal The preset geographical range where the point is located; determine the spectrum resources of the preset private network in the geographical location of the transition cell; configure the transition cell according to the spectrum resources to the preset private network in the geographical location. The same-frequency neighboring cells of the source cell eliminate the need for the high-speed rail private network to enable inter-frequency measurement for the preset public network, preventing high-speed rail users from measuring surrounding public networks and reducing the risk of high-speed rail users leaving the high-speed rail private network; and the adjacent cell configuration operation is simple and It is accurate and can play a guiding role in transitional cells when there are no coverage holes or weak coverage; and by configuring transitional cells as co-frequency neighboring cells, co-channel interference is avoided and the convenience of co-frequency switching can be achieved.

The network resource configuration method provided by the embodiment of the present invention has been introduced above. The network resource configuration device provided by the embodiment of the present invention will be introduced below with reference to the accompanying drawings.

Referring to Figure 4, an embodiment of the present invention provides a network resource configuration device. The device includes:

The acquisition module 401 is used to acquire the mobile parameter data of the terminal in the target area within the preset statistical period; wherein the target area is the overlapping coverage area of the preset private network and the preset public network.

The target area is the overlapping coverage area of the default private network and the default public network, that is, the area is covered by both the default private network and the default public network.

The default private network can be a high-speed rail private network or other communication private network, and the default public network can be a high-speed public network or other ordinary public networks. As a first example, as shown in Figure 2, the solid line in Figure 2 represents the highway and the dotted line represents the high-speed rail; if there are both highways and high-speed rail lines in Figure 2, this area is a target area. The movement parameter data of the terminal may be the terminal's movement speed, movement direction, etc., or the terminal's acceleration data. Within a preset statistical period, obtain the movement parameter data of all terminals in the target area within the statistical period.

The cell determination module 402 is configured to determine a transition cell according to the movement parameter data; wherein the transition cell is a preset geographical range in which key points of the terminal's movement trend are located.

Among them, the key point of the movement trend can be the position point where the terminal acceleration changes beyond the preset ratio, such as the movement direction changes, or the movement speed changes, and the amplitude of the change exceeds the preset amplitude, then the position can be determined points are key points. Take the overlapping coverage of high-speed and high-speed rail as an example. When the moving direction changes or the moving speed changes, for high-speed users, it is likely that the high-speed user side leaves the private network coverage and switches back to the public network. This position is the high-speed The location is separated from the high-speed rail, that is, the default private network is separated from the default public network. High-speed rail users (i.e., high-speed rail private network users) at this location can easily leave the default private network.

It can be understood that the determination of key points is based on the form of big data, that is, the terminal movement parameter data within the statistical period. Due to the large number of statistics, the specific location of the key points of each terminal may have a certain deviation. Therefore, it can be Set a geographical range. For example, if the key points of two terminals are within a preset distance, the two key points can be identified as one key point. Therefore, for multiple key points that meet the preset distance, statistics can be used Determine a key point that is the shortest total distance from all key points in the form of A community transitioning to the default public network.

The resource determination module 403 is used to determine the spectrum resources of the preset private network in the geographical location of the transition cell.

Among them, after the transition cell is determined, the spectrum resources of the preset private network at the location of the transition cell are determined according to the geographical location of the transition cell, so as to determine the spectrum resources of the transition cell based on the spectrum resources of the preset private network; optionally, Spectrum resources can include frequency bands, center frequency point numbers, etc.

The configuration module 403 is configured to configure the transition cell as a co-frequency neighboring cell of the source cell of the preset private network in the geographical location according to the spectrum resources.

Among them, as a third example, as shown in Figure 3, taking the high-speed rail private network as an example, due to the high speed of high-speed rail, in order to reduce the risks caused by handover operations, the high-speed rail private network generally adopts the strategy of merging multiple cells, that is, one source Multiple remote devices are connected, as shown in Cell A and Cell B in the figure. Multiple remote devices are connected to each cell; therefore, the same base station signal is covered within 2-3 kilometers along the high-speed railway. Users do not need to switch when moving during this period; at the same time, because the high-speed rail track is narrow, the high-speed rail private network uses high-gain narrow-beam antennas to enhance the coverage in the carriage.

If the high-speed rail private network near the transitional cell geographically belongs to two different source cells, high-speed users may occupy any one of the cells to leave the expressway. Therefore, both source cells need to add reselection and measurement frequency for the public network. point, then, within the 6 kilometers corresponding to the two source cells, high-speed rail users may also leave the high-speed rail private network and enter the public network, which cannot be completely avoided; therefore, when setting the frequency of the transition cell, it is not necessary to set the current The frequency of the public network is set to the frequency of the transition cell.

Considering that current 4G terminals need to perform co-frequency measurements at any time, and the network side cannot control the co-frequency measurement behavior, if the co-frequency strategy with the high-speed rail private network is adopted, the network parameters do not need to be adjusted.
