In recent years, communication awareness integration has become a popular research direction and is considered as one of important technical directions of wireless communication network evolution in the future.

Fig. 1 shows one configuration of the perception system. In some embodiments, as shown in fig. 1, the perception system comprises: AMF101, at least one edge aware network element 102 and at least one aware base station 103.

Wherein the AMF101 is communicatively connected to at least one edge aware network element 102. The AMF101 is communicatively coupled to at least one cognitive base station 103. Each of the at least one edge aware network element 102 is communicatively connected to a part of the at least one aware base station 103.

In the present application, the AMF101 is configured to: the amount of demand resources that perceives the demand is determined. When the required resource amount is larger than a first preset threshold value, selecting the to-be-selected sensing network element with the resource utilization rate smaller than a second preset threshold value from at least one to-be-selected sensing network element, and determining the to-be-selected sensing network element as a target sensing network element. And triggering the target sensing network element to send a base station sensing activation message to the target sensing base station based on the sensing requirement.

Wherein, the at least one to-be-selected sensing network element is at least one target edge sensing network element connected with the target sensing base station. The target sensing base station is a sensing base station with the base station capability meeting the sensing requirement in at least one sensing base station. The base station perception activation message is used for indicating the target perception network element to carry out wireless signal perception based on the perception requirement. The sense base station 103 is a base station that can perform wireless signal sensing by sensing wireless signals of cells.

Specifically, after the AMF101 obtains the perceived need, the amount of the required resources of the perceived need, that is, the amount of resources consumed for wireless signal perception according to the perceived need, may be determined. Then, when the required resource amount of the perceived need is greater than the first preset threshold, the AMF101 may determine that the perceived need is a heavy load demand.

In addition, the AMF101 may determine a plurality of candidate sensing network elements based on the sensing requirement. Then, the AMF101 may determine resource utilization rates of the plurality of to-be-selected sensing network elements, and select the to-be-selected sensing network element with the resource utilization rate smaller than the second preset threshold value to determine as the target sensing network element. The AMF101 may then trigger the target-aware network element to cause the target-aware network element to send a base station aware activation message to the target-aware base station.

It should be noted that, since the sensing base station 103 senses wireless signals through sensing cells, the base station capability of the sensing base station 103 may include a sensing range (also referred to as a coverage area) and sensing capability of each sensing cell in the sensing base station 103. In addition, the perceived need may also include the perceived range and perceived capabilities required to meet the perceived need. In this case, the base station capability of the sense base station 103 meets the sense requirement, that is, the sense range and sense capability of the sense cell in the sense base station 103 meet the sense range and sense capability in the sense requirement.

Alternatively, when the target sensing base station is one and the target edge sensing network elements connected to the target sensing base station are multiple, the AMF101 may select one target edge sensing network element from the multiple target edge sensing network elements as the to-be-selected sensing network element. When there are multiple target sensing base stations (and each target sensing base station can individually meet sensing requirements), the AMF101 may select one target edge sensing network element from multiple target edge sensing network elements connected by the multiple target sensing base stations as a to-be-selected sensing network element.

Optionally, in this application, when the base station capabilities of the multiple sensing base stations 103 jointly meet the sensing requirement, the multiple sensing base stations 103 may form a target sensing base station combination, and determine at least one edge sensing network element 102 connected to the target sensing base station combination as a candidate sensing network element.

In addition, when the target sensing base station (or the target sensing base station combination) is plural, the AMF101 may randomly select one target sensing base station (or the target sensing base station combination) from the plural target sensing base stations (or the plural target sensing base station combinations). Correspondingly, the base station capability of the sensing network element is the sensing range and sensing capability of the sensing cells of all sensing base stations connected by the sensing network element.

Alternatively, the selection of the candidate sensing network element by the AMF101 may be performed by a simple matching algorithm, or may be performed by any other algorithm, which is not limited in this embodiment of the present application.

Optionally, the AMF101 may further determine, based on the sensing requirement, a target sensing base station whose base station capability meets the sensing requirement, and determine a plurality of candidate sensing network elements connected to the target sensing base station, which is not limited in the embodiment of the present application.

Optionally, when the required resource amount of the sensing requirement is less than or equal to the first preset threshold, the AMF101 may randomly select one to-be-selected sensing network element from the plurality of to-be-selected sensing network elements as the target sensing network element, or select the to-be-selected sensing network element with the resource utilization rate less than the second preset threshold as the target sensing network element, or select the to-be-selected sensing network element through other matching algorithms.

Optionally, the AMF101 may sort the plurality of to-be-selected sensing network elements according to the resource utilization rates of the plurality of to-be-selected sensing network elements, and select a to-be-selected sensing network element with the minimum resource utilization rate from the plurality of to-be-selected sensing network elements to determine the to-be-selected sensing network element as the target sensing network element.

And performing wireless signal sensing based on the base station sensing activation message, and determining first sensing data corresponding to the sensing requirement. And sending the second perception data to the target perception network element through the AMF.

The second perception data is the first perception data or the processed first perception data. The base station aware activation message includes a awareness requirement.

Specifically, the target-aware base station may receive a base station aware activation message sent by the target-aware network element. The base station perception activation message is used for indicating the target perception base station to carry out wireless signal perception based on the perception requirement, so that the target perception base station can carry out wireless signal perception based on the perception requirement in the base station perception activation message after receiving the base station perception activation message so as to obtain first perception data (namely original data) corresponding to the perception requirement.

In addition, the target sensing base station can directly send the first sensing data to the target sensing network element, and can also process the first sensing data to obtain sensing results, such as positioning, tracking, environment and the like, corresponding to the sensing requirements, namely the processed first sensing data, so that the target sensing base station can send the second sensing data to the target sensing network element.

In this way, the AMF101 determines the target sensing network element for processing the sensing requirement, the target sensing network element determines the target sensing base station for processing the sensing requirement, the division is clear, the load of the AMF101 can be reduced, the sensing base station 103 and the sensing requirement can be better managed, and the AMF101 is the equipment in the core network, so that the sensing system has higher suitability for the existing network architecture, can meet diversified sensing requirements, and is applied to various scenes.

It should be noted that, the target sensing base station sends the second sensing data to the target sensing network element through the UPF, that is, the target sensing base station sends the second sensing data to the UPF, and after receiving the second sensing data, the UPF sends the second sensing data to the target sensing network element.

In one possible implementation, the sensing system further includes a sensing demand device. AMF101 is communicatively coupled to the perceived-demand device.

In this application, a perceived-demand device is configured to: the perceived need is sent to the AMF 101.

AMF101, further configured to: a perceived need is received. At least one candidate perceived network element is determined based on the perceived need.

Specifically, the perceived-demand device may send perceived demands to AMF 101. AMF101 may receive the perceived need. The AMF101 may then determine a candidate perceived network element for which the base station capability meets the perceived need based on the perceived need and the access network configuration information stored by itself.

Optionally, the access network configuration information includes an identification of the perceived base station 103 to which each edge perceived network element 102 is connected, a perceived range and perceived capability of each perceived base station 103 (i.e., a perceived range and perceived capability of a perceived cell in each perceived base station 103).

Optionally, after receiving the sensing requirement, the AMF 101 may determine, based on the sensing requirement and the access network configuration information stored in the AMF, a target sensing base station whose base station capability meets the sensing requirement, and determine a central sensing network element or an edge sensing network element connected to the target sensing base station as a to-be-selected sensing network element.

Alternatively, the device for sensing the demand may be a terminal, a server, or other types of electronic devices, and may also be referred to as an application function (Application Function, AF), which is not limited in this embodiment of the present application.

The basic hardware structure of the AMF101 and the sense base station 103 includes elements included in the sense apparatus shown in fig. 6. The following describes the hardware configuration of the AMF101 and the sense base station 103, taking the sense apparatus shown in fig. 6 as an example.

Fig. 6 is a schematic hardware structure diagram of a sensing device according to an embodiment of the present application. The sensing means comprises a processor 21, a memory 22, a communication interface 23, a bus 24. The processor 21, the memory 22 and the communication interface 23 may be connected by a bus 24.

The processor 21 is a control center of the sensing device, and may be one processor or a collective term of a plurality of processing elements. For example, the processor 21 may be a general-purpose central processing unit (central processing unit, CPU), or may be another general-purpose processor. Wherein the general purpose processor may be a microprocessor or any conventional processor or the like.

As one example, processor 21 may include one or more CPUs, such as CPU 0 and CPU 1 shown in fig. 6.

Memory 22 may be, but is not limited to, a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (random access memory, RAM) or other type of dynamic storage device that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), magnetic disk storage or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer.

The following describes the sensing method provided in the embodiments of the present application in detail with reference to the accompanying drawings.

The sensing method provided by the embodiment of the present application is applied to the AMF101 in the sensing system shown in fig. 1, as shown in fig. 7, and the sensing method provided by the embodiment of the present application includes:

s701, AMF determines the required resource amount of the perceived need.

Specifically, after the AMF receives the sensing requirement, the required resource amount of the sensing requirement can be determined according to the sensing frequency, the sensing range and the resources consumed by primary wireless signal sensing.

It should be understood that the AMF may determine, as the required resource amount, a product of the amount of resources consumed by one sensing base station for sensing the wireless signal, the sensing frequency, and the required amount of sensing base stations corresponding to the sensing requirement. Alternatively, the central aware network element determines the product of the amount of resources consumed by the primary aware unit range, the perceived frequency, and the coverage of the perceived need as the amount of required resources.

S702, when the required resource amount is larger than a first preset threshold, the AMF selects a to-be-selected sensing network element with the resource utilization rate smaller than a second preset threshold from at least one to-be-selected sensing network element, and determines the to-be-selected sensing network element as a target sensing network element.

Wherein, the at least one to-be-selected sensing network element is at least one target edge sensing network element connected with the target sensing base station. The target sensing base station is a sensing base station with the base station capability meeting the sensing requirement in at least one sensing base station.

Specifically, when the required resource amount is greater than the first preset threshold, the AMF may determine that the perceived need is a heavy-load perceived need. In addition, the AMF can also determine the to-be-selected sensing network elements meeting the sensing requirement. Then, the AMF can select the to-be-selected sensing network element with the resource utilization rate smaller than a second preset threshold value from the to-be-selected sensing network elements as a target sensing network element.

S703, AMF triggers the target sensing network element to send the base station sensing activation message to the target sensing base station based on the sensing requirement.

The base station perception activation message is used for indicating the target perception network element to carry out wireless signal perception based on the perception requirement. The base station aware activation message includes a awareness requirement.

Specifically, the AMF may determine the target perceived network element based on the perceived need. Then, the AMF may send a network element aware activation message to the target aware network element, so that the target aware network element may determine, based on the network element aware activation cell, a target aware base station with a base station capability meeting a sensing requirement from among the connected aware base stations. Then, the target sensing network element can send a base station sensing activation message to the target sensing base station through the AMF, so that the target sensing base station can sense wireless signals based on the base station sensing activation message, and first sensing data corresponding to sensing requirements are obtained.

From the above, the AMF can select the to-be-selected sensing network element with smaller resource utilization rate for processing when the required resource quantity of the sensing demand is larger, thereby improving the resource utilization rate, improving the processing speed and reducing the time delay. In addition, through the communication perception integrated network architecture formed by the AMF, the edge perception network element and the perception base stations, the target perception base stations meeting the perception demands can be determined, so that the target perception base stations meeting the perception demands can be determined, and diversified perception demands can be met.

In some embodiments, the sensing method provided in the embodiments of the present application may also be applied to a target sensing base station, in which the base station capability in at least one sensing base station 103 in the sensing system shown in fig. 1 meets the sensing requirement, as shown in fig. 8, where the sensing method provided in the embodiments of the present application includes:

s801, a target sensing base station receives a base station sensing activation message sent by a target sensing network element.

The base station perception activation message is used for indicating the target perception base station to carry out wireless signal perception based on the perception requirement. The base station aware activation message includes a awareness requirement. The target sensing network element is at least one sensing network element to be selected, wherein the resource utilization rate of the sensing network element to be selected is smaller than a second preset threshold value; the at least one to-be-selected sensing network element is at least one target edge sensing network element connected with the target sensing base station.

Specifically, before performing wireless signal sensing, the target sensing base station may receive a base station sensing activation message sent by the target edge sensing network element through the AMF, so that the target sensing base station may perform wireless signal sensing based on a sensing requirement in the base station sensing activation message.

S802, the target sensing base station senses wireless signals in response to the base station sensing activation message, and determines first sensing data corresponding to sensing requirements.

Specifically, after receiving the base station perception activation message, the target perception base station can perform corresponding wireless signal perception according to the perception requirement in the perception activation message so as to obtain first perception data corresponding to the perception requirement, namely, original data.

S803, the target sensing base station sends second sensing data to the target sensing network element.

The second perception data is the first perception data or the processed first perception data.

Specifically, after the first sensing data is obtained, the target sensing base station may directly send the first sensing data to the target sensing network element, or may process the first sensing data, so as to send the processed first sensing data to the target sensing network element.

From the above, the target sensing base station may receive the base station sensing activation message sent by the target sensing network element, and because the target sensing base station is the sensing base station determined by the target sensing network element (or AMF) to meet the sensing requirement, the target sensing base station may process the sensing requirement. In this way, the communication perception integrated network architecture formed by the AMF, the edge perception network element and the perception base station can determine the target perception base station meeting each perception requirement, thereby meeting diversified perception requirements.

Fig. 9 shows another structural schematic diagram of the sensing system. Illustratively, the AMF is configured to: receiving the sensing requirement, receiving the access network configuration information of the edge sensing network elements SFd1 and SFd2, selecting a target sensing network element, sending a network element sensing activation message to the target sensing network element, and forwarding a base station sensing activation message sent by the target sensing network element to the target sensing base station.

The cognitive base station is configured to: receiving the base station sensing activation message sent by the edge sensing network elements SFd1 and SFd2 through the AMF, and sending second sensing data (first sensing data or data after processing the first sensing data) to the edge sensing network elements SFd1 and SFd 2.

In addition, the sensing base station sends the second sensing data to the UPF when sending the second sensing data to the target edge sensing network element. After receiving the second sensing data, the UPF sends the second sensing data to the target sensing network element.
