Among a plurality of internet of things communication technologies, a Low Power Wide Area Network (LPWAN) technology well meets data transmission requirements for services (such as intelligent meter reading) with high requirements on Power consumption and coverage in internet of things connection requirements due to the outstanding advantages of Low Power consumption, Wide coverage and the like. Cellular Internet of Things technologies such as Narrow Band Internet of Things (NB-IoT) and enhanced Machine Type Communication (eMTC) established by the 3GPP organization are representative of LPWAN technologies, and are emerging technologies that can be widely applied worldwide.
In order to meet the requirement of low Power consumption, cellular internet of things technologies such as NB-IoT and eMTC simplify or remove the function of reporting a Measurement Report (MR), that is, a terminal device accessing the NB-IoT network or the eMTC network does not Report the MR to an access network device, so that an operator cannot directly obtain parameters related to network quality such as Reference Signal Receive Power (RSRP) from the MR reported by the terminal device. In this case, the operator can only determine the network quality of the internet of things by the conventional drive test method. The traditional drive test method is time-consuming and labor-consuming and has low efficiency. Therefore, operators are in need of a new method for improving the efficiency of determining the network quality of the internet of things.

The internet of things includes but is not limited to: NB-IoT networks and eMTC networks.
As shown in fig. 2, a network quality determination method provided in the embodiment of the present application is applied to a communication system constructed by a communication network and an internet of things in a co-location manner shown in fig. 1, and the method includes:
s101, the network equipment acquires at least one MR reported by the terminal equipment accessing the communication network.
The network device may be a background server of an operator or a core network device.
It should be noted that the MR reported by the terminal device accessing the communication network includes: and the RSRP of the communication network at the position of the terminal equipment. Of course, the MR may also include other parameters, such as Signal to Interference plus Noise Ratio (SINR), Reference Signal Receiving Quality (RSRQ), and Received Signal Strength Indicator (RSSI).
In practical application, the triggering mode of reporting the MR by the terminal device accessing the communication network includes: a periodic trigger or an event trigger. For the periodic trigger mode, the MR reporting period of the terminal device is configured by a high layer or predefined. Illustratively, the event triggers include: and the terminal equipment is used for calling, or the terminal equipment is switched from an idle state to a connected state.
In an optional implementation manner, the network device periodically obtains, from an access network device or a core network device of the communication network, the MR reported by the at least one terminal device accessing the communication network. Or after the terminal device accessing the communication network reports the MR to the access network device or the core network device of the communication network, the access network device or the core network device of the communication network immediately forwards the MR to the network device.
S102, the network equipment determines RSRP distribution information of the Internet of things according to a preset mapping relation and the MR reported by the at least one terminal equipment accessing the communication network.
The preset mapping relation is used for representing the relation between the RSRP of the Internet of things in a target place and the RSRP of the communication network in the target place. It should be noted that the target location is any location in a cell, and this is not limited in this embodiment of the application.
The RSRP distribution information of the Internet of things is used for indicating the RSRP of at least one place of the Internet of things in a cell. Specifically, the RSRP distribution information of the internet of things includes: geographical coordinate information of the place, and RSRP corresponding to the place. For example, the geographic coordinate information may be latitude and longitude information.
Optionally, the RSRP distribution information of the internet of things may be used in aspects of evaluating coverage of the internet of things, guiding application deployment of the internet of things, guiding an operator to optimize the internet of things, and the like.
Before the RSRP distribution information of the Internet of things is determined, the network equipment determines a preset mapping relation according to the signal frequency and the signal transmitting power of the communication network and the signal frequency and the signal transmitting power of the Internet of things.
It should be noted that, there is a corresponding relationship between the RSRP of the target location and the signal transmission power of the internet of things in the internet of things, and the corresponding relationship can be expressed as the following formula (1):
Pr2＝Pt2-L2 (1)
wherein, Pr2Representing the RSRP, P of the Internet of things at a target sitet2Signal emission power, L, representing the Internet of things2The transmission loss of the internet of things is represented. It should be noted that, taking the free space electromagnetic wave transmission loss model as an example, L2＝32.45+20lg(fr2)+20lg(d2). Wherein f isr2To representSignal frequency of the Internet of things, d2The distance between the base station of the internet of things and the target location is represented.
The signal transmitting power and the signal frequency of the internet of things are pre-configured by the access device of the internet of things, so that the network device can acquire the signal transmitting power and the signal frequency of the internet of things from the access device or the database of the internet of things.
It should be noted that, in the communication network, there is a corresponding relationship between the RSRP of the target location and the signal transmission power of the communication network, and the corresponding relationship can be expressed as the following formula (2):
Pr1＝Pt1-L1 (2)
wherein, Pr1Indicating RSRP, P of said communication network at a target sitet1Representing the signal transmission power, L, of said communication network1Representing the transmission loss of the communication network. It should be noted that, taking the free space electromagnetic wave transmission loss model as an example, L1＝32.45+20lg(fr1)+20lg(d1). Wherein f isr1Representing the frequency of the signal of the Internet of things, d1Representing the distance between a base station of the communication network and the target location.
The signal transmission power of the communication network and the signal frequency of the communication network are pre-configured by the access device of the communication network, so that the network device can acquire the signal transmission power of the communication network and the signal frequency of the communication network from the access device or the database of the communication network.
Because the Internet of things and the communication network are constructed in a co-site mode, the internet of things and the communication network are constructed in a co-site mode, so that d1Is equal to d2. Thus, combining the formula (1) and the formula (2) can determine that the preset mapping relationship is the following formula (3)
Further, the above formula (3) may add an empirical constant to correct the error, considering a complicated practical environment and a difference in antenna gain between the terminal of the internet of things and the terminal of the communication network. Specifically, the above formula (3) can be modified into the following formula (4):
wherein, delta is a constant and is used for reflecting errors brought by aspects of actual environment and the like. The delta can be determined by experts or by big data methods.
Based on the technical scheme, in a communication system constructed by a communication network and an internet of things in a co-site manner, for a certain location in a cell, the distance between the location and a base station where the internet of things is located is equal to the distance between the location and the base station where the communication network is located, and the interference suffered in the process of transmitting the signals of the internet of things to the location is also equal to the interference suffered in the process of transmitting the signals of the communication network to the location. Therefore, the network device determines the RSRP of at least one place of the communication network in the cell by acquiring the MR reported by at least one terminal device accessing the communication network; and then, the network equipment determines the RSRP distribution information of the Internet of things according to the relation between the RSRP of the Internet of things in the target location and the RSRP of the communication network in the target location, namely determines the RSRP of the Internet of things in at least one location in the cell. Therefore, an operator can directly determine the network quality of the Internet of things according to the data of the communication network without adopting a drive test method to determine the network quality of the Internet of things, so that the efficiency of determining the network quality of the Internet of things is improved.
In the embodiment of the present application, the network device may be divided into the functional modules or the functional units according to the above method examples, for example, each functional module or functional unit may be divided corresponding to each function, or two or more functions may be integrated into one processing module.
