Among them, both AMF network elements and RAN equipment can be operator networks, such as network elements in the Public Land Mobile Network (PLMN). The architecture of the operator network can be shown in Figure 1.

Please refer to Figure 3. This embodiment of the present application provides an AP adaptive method in an enterprise-level full coverage environment. The method includes:

S301. The AMF network element sends a regional signal assessment request to the RAN device.

The regional signal evaluation request can be used to request the RAN device to evaluate the signal quality of the enterprise area. The service range of the RAN device covers the enterprise area. Optionally, the regional signal evaluation request is also used to indicate the signal quality evaluation granularity of the enterprise region. For example, the regional signal assessment request includes one or more of the following: the identity of the third-party AF, the identity of the RAN device, information used to indicate the enterprise area, an information element used to request signal quality, or used to indicate the signal quality assessment granularity. This one or more information elements are used to jointly indicate to request the RAN device to evaluate the signal quality of the enterprise area at the signal quality assessment granularity of the enterprise area.

A third-party AF is an AF belonging to an enterprise whose campus includes the above-mentioned enterprise area. The third-party AF can trigger the AMF network element to send a regional signal assessment request to the RAN device. The identifier of the third-party AF is used to uniquely indicate the third-party AF. The identifier of the RAN device is used to uniquely indicate the RAN device. The information used to indicate the enterprise area may be latitude and longitude information indicating the enterprise area. The signal quality evaluation granularity can be used to indicate the granularity of rasterizing the enterprise area. If the rasterization granularity is higher, the size of each raster obtained by rasterization will be smaller. The signal quality of the enterprise area is determined by An indication of signal quality for each grid in the enterprise area.

One possible way:

Step 1: The AMF network element can receive the capability opening request from the third-party AF.

Among them, the capability opening request is used to request the operator network to open the signal quality of the enterprise area; for example, the capability opening request includes at least one of the following: the identifier of the third-party AF, the identifier of the operator network, information used to indicate the enterprise area, or An information element used to request signal quality; at least one of these items may be used to jointly request signal quality in an open enterprise area of the operator's network.

Step 2: The AMF network element can send a regional signal assessment request to the RAN device according to the capability opening request.

First, the AMF network element determines the contract status between the enterprise and the operator's network based on the identification of the third-party AF.

For example, the AMF network element can traverse the third-party applications contracted with the operator's network to see whether there is a third-party AF based on the identification of the third-party AF. For example, the AMF network element can locally pre-configure a subscription list. The subscription list includes the identification of the third-party application contracted with the operator network, and the contracting level corresponding to the identification of the third-party application. That is, the third-party application and The contracting levels of the operator's network are, from low to high, level 1, level 2, level 3, level 4, etc. If there is a third-party AF among the third-party applications contracted with the operator network (for example, the contract list contains the identification of the third-party AF), the AMF network element determines the contract level between the third-party AF and the operator network. Or, if there is no third-party AF among the third-party applications contracted with the operator network, the AMF network element determines the contract level of other AFs related to the third-party AF and the operator network. For example, the AMF network element can locally pre-configure the relationship list of the third-party application. The relationship list is used to indicate which AFs are related, such as AF1 is related to AF2, AF3, AF3 and AF5 are related. The related AFs can be of the same service type. AF, or AF with similar QoS requirements, there is no restriction on this. In this way, the AMF network element can determine other AFs related to the third-party AF and contracted with the operator network based on the relationship list and the contract list, and obtain the contract level of the other AFs. Among them, if there are multiple other AFs related to the third-party AF and contracted with the operator's network, the AMF network element selects the AF with the lowest contract level.

Then, the AMF network element can determine the signal quality assessment granularity of the enterprise area based on the contract status.

For example, when the third-party AF signs a contract with the operator network, the AMF network element can determine the signal quality assessment granularity of the enterprise area based on the contract level between the third-party AF and the operator network. Among them, if the contract level between the third-party AF and the operator network is higher, the signal quality assessment granularity of the enterprise area corresponding to the contract level between the third-party AF and the operator network indicates a higher granularity for rasterizing the enterprise area. Specifically, if the contract level between the third-party AF and the operator's network is greater than or equal to the preset level threshold, the AMF network element will evaluate the first signal quality granularity corresponding to the contract level between the third-party AF and the operator's network, and the operator's The second signal quality assessment granularity corresponding to the lowest subscription level of the network is determined as the signal quality assessment granularity of the enterprise area. Wherein, the level threshold is between the highest subscription level of the operator network and the lowest subscription level of the operator network, and the rasterized granularity indicated by the first signal quality assessment granularity is higher than the rasterized granularity indicated by the second signal quality assessment granularity. granularity. Or, if the contract level between the third-party AF and the operator network is less than the preset level threshold, the AMF network element determines the third signal quality assessment granularity corresponding to the contract level between the third-party AF and the operator network as the signal in the enterprise area. Quality assessment granularity.

For another example, when the third-party AF does not have a contract with the operator network, the AMF network element determines the signal quality evaluation granularity of the enterprise area based on the contract level of other AFs with the operator network. Among them, if the contract level of other AFs and the operator network is higher, the signal quality assessment granularity of the enterprise area corresponding to the contract level of other AFs and the operator network indicates a higher granularity for rasterizing the enterprise area. Specifically, if the contract level of other AFs and the operator network is greater than or equal to the preset level threshold, the AMF network element will use the first signal quality evaluation granularity corresponding to the contract level of other AFs and the operator network, and the first signal quality evaluation granularity of the operator network. The second signal quality assessment granularity corresponding to the lowest subscription level is determined as the signal quality assessment granularity of the enterprise area, where the level threshold is between the highest subscription level of the operator network and the lowest subscription level of the operator network. The first signal quality assessment The granularity indicates a rasterized granularity that is higher than the rasterized granularity indicated by the second signal quality assessment granularity. If the contract level of other AFs and the operator network is less than the preset level threshold, the AMF network element determines the third signal quality assessment granularity corresponding to the contract level of other AFs and the operator network as the signal quality assessment granularity of the enterprise area.

Finally, the AMF network element can determine the information element used to indicate the signal quality assessment granularity according to the signal quality assessment granularity of the enterprise area, such as the first signal quality assessment granularity and the second signal quality assessment granularity, or the third signal quality assessment granularity, And based on the information used to indicate the enterprise area, the identification of the RAN equipment that the cell can cover in the enterprise area is determined. In this way, the AMF network element can encapsulate the identifier of the third-party AF, the identifier of the RAN device, the information used to indicate the enterprise area, the information element used to request signal quality, and the information element used to indicate the signal quality assessment granularity to obtain the area Signal assessment request, and send the area signal assessment request to the RAN device.

S302. The AMF network element receives the regional signal assessment response from the RAN device.

Among them, the regional signal evaluation response is used to indicate the signal quality evaluation result of the enterprise region. The RAN device can grid the enterprise area based on the information element used to indicate the signal quality assessment granularity, and instruct the terminals in each grid to report the signal quality (such as RSRP), and then the terminals in each grid report the The signal quality is weighted and averaged to obtain the signal quality of each grid, and finally the signal quality of each grid is returned to the AMF network element through the regional signal evaluation response.

S303: The AMF network element determines the AP deployment strategy in the enterprise area based on the signal quality evaluation results.

Among them, the AP deployment strategy is used to provide access services to the enterprise's internal network by deploying APs in the enterprise area. The internal network and the operator's network are different networks.

When the subscription level is greater than or equal to the level threshold, the signal quality evaluation result includes a first signal quality evaluation result and a second signal quality evaluation result. Among them, the first signal quality evaluation result is used to indicate the signal quality of each of the M grids obtained by dividing the enterprise area, and the second signal quality evaluation result is used to indicate the signal quality of each of the N grids obtained by dividing the enterprise area. The signal quality of each grid, M and N are integers greater than 1, and M is greater than N. In this way, the AMF network element can determine M1 grids among the M grids whose signal quality is less than the preset signal quality threshold based on the signal quality of each of the M grids, and determine each of the N grids. The signal quality of the grid determines the N1 grids among the N grids whose signal quality is less than the signal quality threshold. The AMF network element can map the areas corresponding to N1 grids to M grids, and obtain M2 grids among the M grids whose signal quality is less than the preset signal quality threshold, and M2 is greater than or equal to M1. The AMF network element can determine the location and number of APs deployed in the area corresponding to the M2 grids based on the location distribution of the M2 grids in the enterprise area, where the number of APs deployed in the area corresponding to the M2 grids The location and number are AP deployment strategies within the enterprise area.

Specifically, the AMF network element can determine the location and number of APs deployed in the area corresponding to the M2 grids based on the location distribution of the M2 grids in the enterprise area. The AMF network element may determine the number of APs deployed in the area corresponding to the M1 grids as the second number based on the number of M2 grids. Among them, the number of M2 grids is positively related to the second number. Furthermore, the AMF network element can also determine the locations of the second number of APs in at least one area based on at least one area corresponding to the M2 grilles in the enterprise area and the preset location setting rules. Among them, when at least one area is more than two areas, the two or more areas are not connected to each other; the location setting rules include: at least one AP needs to be evenly located in each area, and the APs set in each area The number is directly related to the size of the area.

When the subscription level is less than the level threshold, the signal quality evaluation result includes a third signal quality evaluation result. Among them, the third signal quality evaluation result is used to indicate the signal quality of each of the M grids obtained by dividing the enterprise area, and the second signal quality evaluation result is used to indicate the signal quality of each of the N grids obtained by dividing the enterprise area. The signal quality of each grid, M is an integer greater than 1. In this way, the AMF network element can determine M1 grids among the M grids whose signal quality is less than the preset signal quality threshold based on the signal quality of each grid among the M grids. The AMF network element determines the location and number of APs deployed in the areas corresponding to the M1 grids based on the location distribution of the M1 grids in the enterprise area, where the locations of the APs deployed in the areas corresponding to the M1 grids are and number are AP deployment strategies within the enterprise area.

Specifically, the AMF network element may determine the number of APs deployed in the area corresponding to the M2 grids as the first number based on the number of M1 grids. Among them, the number of M1 grids is positively related to the first number. And, the AMF network element can determine the locations of the first number of APs in at least one area based on at least one area corresponding to the M1 grilles in the enterprise area and the preset location setting rules. Among them, when at least one area is more than two areas, the two or more areas are not connected to each other; the location setting rules include: at least one AP needs to be evenly located in each area, and the APs set in each area The number is directly related to the size of the area.

It can be understood that the AP deployed in the area corresponding to the M1 grids or the area corresponding to the M2 grids is an enhanced AP. The enhanced AP is equipped with two antenna panels. The two antenna panels of the enhanced AP simultaneously transmit wide beams and narrow beams. The beams can be merged into an enhanced beam; among them, the wide beam and the narrow beam sent simultaneously by the two antenna panels of the enhanced AP can be merged into an enhanced beam means: the two antenna panels of the enhanced AP can send wide beams in the same direction at the same time. and narrow beams (for example, antenna panel #1 sends a wide beam, and antenna panel #2 sends a narrow beam), so that the wide beam and the narrow beam can be superimposed into an enhanced wave. That is to say, physically, there are actually two beams, but logically it can be considered as one beam, and the coverage area of this beam is the union of the wide beam and the narrow beam. In addition, APs deployed in areas other than the area corresponding to M1 grids or the area corresponding to M2 grids in the enterprise area are ordinary APs, and ordinary APs are equipped with one antenna panel.

In other words, it can facilitate the opening of the operator's network capabilities, and conduct signal measurements in designated areas, such as enterprise areas, to measure low-signal areas, such as the areas corresponding to the above-mentioned M1 grids or M2 grids. These areas are limited by physical reasons, such as closed buildings, blocked buildings, strong signal interference, etc., resulting in poor signal quality in the area itself. Therefore, enhanced APs need to be deployed in these areas to improve access. capabilities to ensure user experience.

To sum up:

With the capability openness of the operator network, the operator network can help third parties measure the signal quality of the enterprise area. For example, the AMF network element in the operator network can measure the signal quality evaluation results of the enterprise area through the RAN equipment in the operator network. . In this way, the operator network, such as the AMF network element, can determine the AP deployment strategy in the enterprise area based on the signal quality of the enterprise area, so that the access services provided by the AP can match the actual signal quality of different areas, thereby ensuring that users can Actual usage requirements.
