The technical solutions in the present application will be described below with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a communication system, which may specifically include: AMF network element and RAN equipment. Wherein both the AMF network element and the RAN device may be operator networks, such as network elements in a public land mobile network (Public Land Mobile Network, PLMN), the architecture of which may be as shown in fig. 1.

The interaction between the AMF network element and the RAN device in the above communication system will be described in detail with reference to the method.

Referring to fig. 3, an embodiment of the present application provides an AP adaptation method in an enterprise-level full coverage environment, where the method includes:

s301, the AMF network element sends a regional signal evaluation request to the RAN device.

The regional signal evaluation request may be used to request the RAN device to evaluate the signal quality of the enterprise region, the service area of the RAN device covering the enterprise region. Optionally, the regional signal evaluation request is further used to indicate a signal quality evaluation granularity of the enterprise region. For example, the zone signal evaluation request includes one or more of the following: the one or more of the identification of the third party AF, the identification of the RAN device, the information indicative of the enterprise area, the information indicative of the request for signal quality, or the information indicative of the granularity of signal quality assessment are used to jointly indicate the granularity of signal quality assessment at the enterprise area, requesting the RAN device to assess the signal quality at the enterprise area.

The third party AF is an AF belonging to an enterprise whose campus contains the enterprise area described above. The third party AF may trigger the AMF network element to send a regional signal evaluation request to the RAN device. The identification of the third party AF is used to uniquely indicate the third party AF. The identification of the RAN device is used to uniquely indicate the RAN device. The information indicating the enterprise area may be latitude and longitude information indicating the enterprise area. The signal quality assessment granularity may be used to indicate the granularity of rasterizing the enterprise area, with the higher the granularity of rasterization, the smaller the size of each grid that results from rasterization, and the signal quality of the enterprise area is represented by the signal quality of each grid in the enterprise area.

In one possible way:

in step 1, the amf network element may receive a capability open request from a third party AF.

Wherein the capability opening request is used for requesting the signal quality of the operator network open enterprise area; for example, the capability open request includes at least one of: an identification of a third party AF, an identification of an operator network, information indicating an enterprise area, or a cell for requesting signal quality; this at least one item may be used to jointly request signal quality of an open enterprise area of the operator network.

Step 2, the amf network element may send a regional signal evaluation request to the RAN device according to the capability open request.

Firstly, the AMF network element determines the signing condition of the enterprise and the operator network according to the identification of the third party AF.

For example, the AMF network element may traverse whether there is a third party AF in the third party application subscribed to the carrier network according to the identification of the third party AF. For example, the AMF network element may locally pre-configure a subscription list, where the subscription list includes an identifier of a third party application subscribed to the carrier network, and a subscription level corresponding to the identifier of the third party application, that is, a subscription level of the third party application to the carrier network, e.g., from low to high, e.g., level 1, level 2, level 3, level 4, etc. If there is a third party AF in the third party application subscribed to the operator network (e.g., the subscription list includes an identifier of the third party AF), the AMF network element determines a subscription level of the third party AF to the operator network. Or if the third party AF does not exist in the third party application subscribed with the operator network, the AMF network element determines the subscription level of other AF related to the third party AF and the operator network. For example, the AMF network element may locally pre-configure a relationship list of the third party application, where the relationship list is used to indicate which AFs are related, such as AF1 is related to AF2, AF3, and AF5 are related, and related AFs may be AF of the same service type or AF with similar QoS requirements, which is not limited. Thus, the AMF network element may determine, according to the relationship list and the subscription list, other AFs related to the third party AF and subscribed to the operator network, and obtain subscription levels of the other AFs. If there are a plurality of other AFs related to the third party AF and subscribed to the operator network, the AMF network element selects the AF with the lowest subscription level.

The AMF network element may then determine a signal quality assessment granularity for the enterprise area based on the subscription.

For example, when the third party AF signs up with the operator network, the AMF network element may determine the signal quality evaluation granularity of the enterprise area according to the sign-up level of the third party AF with the operator network. If the subscription level of the third party AF and the operator network is higher, the granularity of the signal quality evaluation granularity indication of the enterprise area corresponding to the subscription level of the third party AF and the operator network for rasterizing the enterprise area is higher. Specifically, if the subscription level of the third party AF and the operator network is greater than or equal to a preset level threshold, the AMF network element determines a first signal quality evaluation granularity corresponding to the subscription level of the third party AF and the operator network, and a second signal quality evaluation granularity corresponding to the lowest subscription level of the operator network as the signal quality evaluation granularity of the enterprise area. Wherein the level threshold is between a highest subscription level of the operator network and a lowest subscription level of the operator network, the granularity of the rasterization of the first signal quality evaluation granularity indication being higher than the granularity of the rasterization of the second signal quality evaluation granularity indication. Or if the subscription level of the third party AF and the operator network is smaller than the preset level threshold, the AMF network element determines the third signal quality evaluation granularity corresponding to the subscription level of the third party AF and the operator network as the signal quality evaluation granularity of the enterprise area.

For another example, when the third party AF has no subscription with the operator network, the AMF network element determines the signal quality evaluation granularity of the enterprise area according to the subscription level of the other AF with the operator network. If the subscription level of the other AF and the operator network is higher, the granularity of the signal quality evaluation granularity indication of the enterprise area corresponding to the subscription level of the other AF and the operator network is higher. Specifically, if the subscription level of the other AFs and the operator network is greater than or equal to a preset level threshold, the AMF network element determines a first signal quality evaluation granularity corresponding to the subscription level of the other AFs and the operator network and a second signal quality evaluation granularity corresponding to the lowest subscription level of the operator network as the signal quality evaluation 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, and the granularity of the graining indicated by the first signal quality evaluation granularity is higher than the granularity of the graining indicated by the second signal quality evaluation granularity. If the subscription level of other AFs and the operator network is smaller than the preset level threshold, the AMF network element determines a third signal quality evaluation granularity corresponding to the subscription level of other AFs and the operator network as the signal quality evaluation granularity of the enterprise area.

Finally, the AMF network element may determine, according to the granularity of signal quality assessment for the enterprise area, a cell indicating the granularity of signal quality assessment, such as a first granularity of signal quality assessment and a second granularity of signal quality assessment, or a third granularity of signal quality assessment, and determine, according to the information indicating the enterprise area, an identity of RAN equipment that the cell is capable of covering the enterprise area. In this way, the AMF network element may encapsulate the identification of the third party AF, the identification of the RAN device, the information indicating the enterprise area, the information for requesting the signal quality, and the information for indicating the granularity of signal quality assessment, obtain an area signal assessment request, and send the area signal assessment request to the RAN device.

S302, the AMF network element receives the area signal evaluation response from the RAN device.

Wherein the regional signal evaluation response is indicative of a signal quality evaluation result for the enterprise region. The RAN device may rasterize the enterprise area according to the cell for indicating the granularity of signal quality evaluation, and instruct the terminal in each grid to report the signal quality (such as RSRP), then weight average the signal quality reported by the terminal in each grid to obtain the signal quality of each grid, and finally return the signal quality of each grid to the AMF network element through the area signal evaluation response.

S303, the AMF network element determines an AP deployment strategy in the enterprise area according to the signal quality evaluation result.

Wherein the AP deployment policy is used to provide access services to an internal network of the enterprise by deploying the AP within the enterprise area, the internal network being a different network than the operator network.

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. The first signal quality evaluation result is used for indicating the signal quality of each of M grids obtained by dividing the enterprise area, the second signal quality evaluation result is used for indicating the signal quality of each of N grids obtained by dividing the enterprise area, M and N are integers greater than 1, and M is greater than N. Thus, the AMF network element may determine, according to the signal quality of each of the M grids, M1 grids of the M grids having a signal quality less than a preset signal quality threshold, determine the signal quality of each of the N grids, and determine N1 grids of the N grids having a signal quality less than the signal quality threshold. The AMF network element may map the areas corresponding to the N1 grids to M grids, to obtain M2 grids, where the signal quality of the M grids is smaller than a preset signal quality threshold, and M2 is greater than or equal to M1. The AMF network element can determine the positions and the numbers of the APs deployed in the areas corresponding to the M2 grids according to the position distribution of the M2 grids in the enterprise area, wherein the positions and the numbers of the APs deployed in the areas corresponding to the M2 grids are the AP deployment strategies in the enterprise area.

Specifically, the AMF network element may determine, according to the position distribution of the M2 grids in the enterprise area, the positions and the number of APs deployed in the area corresponding to the M2 grids. The AMF network element may determine, according to the number of M2 grids, the number of APs deployed in the area corresponding to the M1 grids as the second number. Wherein the number of M2 grids is positively correlated with the second number. And the AMF network element may further determine, according to at least one area corresponding to the M2 grids in the enterprise area and a preset position setting rule, a position of the second number of APs in the at least one area. Wherein, when at least one area is more than two areas, the more than two areas are not connected with each other; the location setting rule includes: at least one AP needs to be uniformly arranged in each area, and the number of APs arranged in each area is positively correlated with 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. The third signal quality evaluation result is used for indicating the signal quality of each of M grids obtained by dividing the enterprise area, and the second signal quality evaluation result is used for indicating the signal quality of each of N grids obtained by dividing the enterprise area, wherein M is an integer greater than 1. Thus, the AMF network element may determine, according to the signal quality of each of the M grids, M1 grids whose signal quality is less than a preset signal quality threshold. The AMF network element determines the positions and the numbers of the APs deployed in the areas corresponding to the M1 grids according to the position distribution of the M1 grids in the enterprise area, wherein the positions and the numbers of the APs deployed in the areas corresponding to the M1 grids are the AP deployment strategies in the enterprise area.

Specifically, the AMF network element may determine, according to the number of M1 grids, the number of APs deployed in the area corresponding to the M2 grids as the first number. Wherein the number of M1 grids is positively correlated with the first number. And the AMF network element may determine, according to at least one area corresponding to the M1 grids in the enterprise area and a preset position setting rule, a position of the first number of APs in the at least one area. Wherein, when at least one area is more than two areas, the more than two areas are not connected with each other; the location setting rule includes: at least one AP needs to be uniformly arranged in each area, and the number of APs arranged in each area is positively correlated with the size of the area.

It can be understood that, the APs deployed in the areas corresponding to the M1 gratings or the areas corresponding to the M2 gratings are enhanced APs, the enhanced APs are provided with 2 antenna panels, and the wide beams and the narrow beams simultaneously transmitted by the 2 antenna panels of the enhanced APs can be fused into one enhanced beam; wherein, the wide beam and the narrow beam which are simultaneously transmitted by the 2 antenna panels of the enhanced AP can be fused into one enhanced beam means that: the 2 antenna panels of the enhanced AP can simultaneously transmit a wide beam and a narrow beam (e.g., antenna panel #1 transmits a wide beam and antenna panel #2 transmits a narrow beam) in the same direction, so that the wide beam and the narrow beam can be superimposed into one enhanced wave. That is, physically, there are actually two beams, but logically, it can be considered one beam whose coverage area is the union of a wide beam and a narrow beam. In addition, APs disposed in areas other than the areas corresponding to the M1 grids or the areas corresponding to the M2 grids in the enterprise area are normal APs, and the normal APs are provided with 1 antenna panel.

That is, the method can be beneficial to the opening of the capability of the operator network, and signal measurement is performed on a designated area, such as an enterprise area, so as to measure a low-signal area therein, such as an area corresponding to M1 grids or an area corresponding to M2 grids, which are limited by physical reasons, such as closed building positions, building shielding, strong signal interference, and the like, so that the signal quality of the area is poor, and therefore, enhanced APs are required to be deployed in the areas to improve the access capability, thereby ensuring the use experience of users.
