Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.

The interoperation of the 5G base station and the 4G base station includes reselection, handover, and redirection. The switching may be based on SINR (Signal to Interference plus Noise Ratio ), among other things. For example, a quality switch threshold is configured to switch from NR (New Radio,5G Radio network) to LTE (Long Term Evolution,3GPP long term evolution), and is triggered when the SINR is below a certain value. However, the existing quality switching threshold only considers SINR, and the consideration factors are not very comprehensive, such as the location information of the terminal in the cell, the terminal rate, and the like are not considered. Since the network rate is an intuitive representation of the terminal network experience, taking the rate into account can better optimize the SINR threshold.

Fig. 1 shows an application scenario diagram of a 5G base station and a 4G base station not co-sited according to an embodiment of the present disclosure. Fig. 2 shows an application scenario diagram of co-sited 5G base station and 4G base station according to an embodiment of the present disclosure. In the application scenario of fig. 1 and fig. 2, when the terminal is located at the edge of the 5G base station (NR), the network speed of the terminal will decrease, and the corresponding SINR value will also decrease, where if the 4G (LTE) base station can provide a service that meets the requirements for the terminal, the terminal transitions from the 5G base station to the 4G base station, and then a good experience will be provided for the user.

Fig. 3 is a flowchart showing a handover method of a base station of a different system according to an exemplary embodiment of the present application, which is described from the 4G base station side. Among them, different systems refer to different network systems, such as a 5G mobile network and a 4G mobile network. The 5G mobile network is for example NR and the 4G mobile network is for example LTE.

As shown in fig. 3, the handover method of the inter-system base station includes:

in step S310, the position and the first rate of the first terminal transmitted by the 5G base station are received.

In this step, the 4G base station receives the position of the first terminal and the first rate transmitted by the 5G base station. The first terminal may be any terminal that receives a service signal, for example, a smart phone. For example, the 5G base station may acquire the location of the first terminal, the first rate, and the first signal-to-interference-plus-noise ratio SINR in real time at a frequency; wherein the position of the first terminal may be obtained in real time, for example, by SRS (Synchronous Relay Satellite, synchronized relay satellite); the first rate may be a network speed obtained by the first terminal at the 5G base station; the first signal to interference plus noise ratio SINR may be an SINR obtained at the 5G base station by the first terminal. When the first SINR is smaller than or equal to the SINR threshold value of the 5G base station, the 5G base station sends the position and the first rate of the first terminal to the 4G base station; the SINR threshold of the 5G base station may be a value that the 5G base station can provide qualified service to the first terminal, and may specifically be set in the 5G base station according to an actual situation. After the 5G base station transmits the position and the first rate of the first terminal to the 4G base station, the 4G base station receives the position and the first rate of the first terminal transmitted by the 5G base station.

In step S320, a second rate of the first terminal is obtained according to the position of the first terminal, where the second rate is a rate under the condition that the 4G base station is simulated according to the position of the first terminal.

In the step, the 4G base station acquires a second rate of the first terminal according to the position of the first terminal, wherein the second rate is a rate obtained by simulating the 4G base station according to the position of the first terminal. In this step, the 4G base station simulates a second rate of the first terminal in the LTE cell by clustering and IDW (Inverse Distance Weight, inverse distance weighted interpolation) algorithms according to the location of the first terminal.

In step S330, when the second rate is greater than the first rate, a second signal to interference plus noise ratio SINR of the first terminal is obtained according to the second rate, where the second SINR is an SINR under the 4G condition simulated according to the location of the first terminal.

In the step, when the second rate is larger than the first rate, the 4G base station obtains a second signal to interference plus noise ratio (SINR) of the first terminal according to the second rate, wherein the second SINR is the SINR under the condition of simulating 4G according to the position of the first terminal. In this step, the 4G base station back-derives CQI (Channel Quality Indicator, channel quality indication) at a second rate and converts to a second SINR.

In step S340, when the second SINR is greater than or equal to the SINR threshold of the 4G base station, a handover notification of the first terminal is sent to the 5G base station, so that the 5G base station notifies the first terminal to switch to the 4G base station.

In this step, when the second SINR is greater than or equal to the SINR threshold of the 4G base station, the 4G base station sends a handover notification of the first terminal to the 5G base station, so that the 5G base station notifies the first terminal to switch to the 4G base station. In this step, based on the second rate being greater than the first rate, the second SINR is further greater than or equal to the SINR threshold of the 4G base station, which indicates that after the first terminal is switched, the first terminal may enjoy a qualified network rate and related services, so the 4G base station may send a switching notification of the first terminal to the 5G base station, so that the 5G base station notifies the first terminal to switch to the 4G base station, thereby enabling the user to have a good network experience.

The switching method of the different system base station of fig. 3 of the present application, the position and the first rate of the first terminal sent by the 5G base station are received by the 4G base station; acquiring a second rate of the first terminal according to the position of the first terminal, wherein the second rate is a rate obtained by simulating a 4G base station according to the position of the first terminal; when the second rate is greater than the first rate, acquiring a second signal to interference plus noise ratio (SINR) of the first terminal according to the second rate, wherein the second SINR is an SINR under the condition of simulating 4G according to the position of the first terminal; and when the second SINR is greater than or equal to the SINR threshold of the 4G base station, sending a switching notification of the first terminal to the 5G base station, so that the 5G base station notifies the first terminal to switch to the 4G base station, thereby providing good service experience for users and ensuring network rate experience of the users.

Fig. 4 is a flowchart showing a method of acquiring a second rate of a first terminal according to a location of the first terminal according to an exemplary embodiment of the present application, which is described from a 4G base station side. Among them, different systems refer to different network systems, such as a 5G mobile network and a 4G mobile network. The 5G mobile network is for example NR and the 4G mobile network is for example LTE.

As shown in fig. 4, the second rate method for acquiring the first terminal according to the position of the first terminal includes:

in step S410, the positions of all terminals in the cell where the position of the first terminal is located are obtained.

In this step, the 4G base station obtains the positions of all terminals in the cell where the position of the first terminal is located. All terminals in the cell where the location of the first terminal is located may be, for example, terminals served by a 4G base station.

In step S420, the location of the first terminal and all the terminal locations in the cell where the location of the first terminal is located are clustered, so as to obtain a first cluster where the first terminal is located.

In this step, the 4G base station clusters the location of the first terminal with all the terminal locations in the cell where the first terminal is located, so as to obtain a first cluster where the first terminal is located.

In the step, after the 4G base station (eNodeB) obtains the position information and the speed of all terminals in the cell corresponding to the position of the first terminal, a new 4G base station algorithm module performs LTE speed simulation of the position of the first terminal by combining the position of the first terminal with all terminal positions in the cell, clusters all the existing terminal positions and distribution characteristics thereof in the cell and the position of the first terminal to be detected, which is reported by the 5G base station (gNodeB), by using a clustering algorithm, namely randomly selecting a plurality of objects in the cell as the center of each cluster, assigning the closest cluster to each object according to the distance between the rest object and the center of each cluster, recalculating the average value of each cluster, updating the average value to be the new cluster center, and continuously repeating the process until the criterion function converges, thereby dividing the objects in the cell into a plurality of clusters, and each cluster has the characteristics.

In step S430, a second rate of the first terminal is obtained by an inverse distance weighted interpolation algorithm IDW within the first cluster range.

In this step, the 4G base station obtains the second rate of the first terminal within the first cluster range by means of an inverse distance weighted interpolation algorithm IDW.

In the step, the position of the first terminal received by the 4G base station is used as a point to be measured, the position of the first terminal is obtained and falls in a first cluster range, the data of the position of the first terminal is obtained by utilizing an inverse distance weighted interpolation algorithm (IDW) in the first cluster range, namely, the distances from the position of the first terminal to all the points in the first cluster where the first terminal is located are calculated, the weight of each point is calculated, namely, the function of the reciprocal of the distance, the reciprocal of each point is divided by the sum of all the reciprocal, the weight of each point can be obtained, and then the rate of the position of the first terminal can be calculated by weighting and summing the weights, and is recorded as a second rate.

Fig. 5 is a flowchart showing a method for acquiring a second SINR of the first terminal according to the second rate according to an exemplary embodiment of the present application, which is described from the 4G base station side. Among them, different systems refer to different network systems, such as a 5G mobile network and a 4G mobile network. The 5G mobile network is for example NR and the 4G mobile network is for example LTE.

As shown in fig. 5, the second SINR method of the first terminal according to the second rate includes:

in step S510, the number of Resource Elements (REs) in the actual physical Resource module PRB (Physical Resource Block, physical Resource module) of the 4G base station is obtained.

In this step, the 4G base station acquires the number of resource elements REs in an actual physical resource module PRB of the 4G base station. Wherein the number of PRBs is known, e.g. 20Mhz corresponds to 100 PRBs. The modulation order corresponding to 64QAM (Quadrature Amplitude Modulation ) is 6. The number of REs in the PRB can be obtained by multiplying the number of symbols (14) of each subframe, the number of PRBs, and the number of REs (12) of each symbol.

In step S520, the total number of bits of the physical channel is obtained according to the number of resource elements REs and modulation orders in the actual physical resource module PRB of the 4G base station.

In this step, the 4G base station obtains the total number of bits of the physical channel according to the number of resource elements REs and modulation orders in the actual physical resource module PRB of the 4G base station.

In this step, to remove the number of REs occupied by CFI (Control Format Indicatior, which is used to indicate the number of symbols occupied by PDCCH in a subframe), the number of REs in the actual PRB is obtained by subtracting the number of PDCCH (Physical Downlink Control Channel ) symbols×the number of prbs×the number of REs per symbol (12). The total number of bits of the physical channel can be further obtained as the number of REs in the actual PRB x the modulation order.

In step S530, a transport block set TBS is acquired according to the second rate and the number of streams, the number of downlink timeslots, and the number of half frames within 1 second of the 4G base station.

In this step, the 4G base station acquires a transport block set TBS according to the second rate and the number of streams, the number of downlink slots, and the number of half frames within 1 second of the 4G base station.

In this step, the maximum TBS that can be carried is calculated from the second rate by the calculation method of second rate/stream number/number of downlink slots/number of half frames in 1 second. Wherein the number of streams, the number of downlink slots, and the number of half frames in 1 second are known.

In step S540, a second code rate corresponding to the second rate is obtained according to the TBS and the total number of bits of the physical channel.

In this step, the 4G base station obtains a second code rate corresponding to the second rate according to the TBS and the total number of bits of the physical channel.

In this step, the maximum TBS +.physical channel total number of bits can be given a two code rate.

In step S550, a second channel quality indicator CQI is obtained according to the second code rate.

In this step, the 4G base station acquires a second channel quality indicator CQI according to the second code rate.

In this step, the code rate may be in one-to-one correspondence with the CQI according to the specification of the LTE protocol.

In step S560, the second SINR is obtained from the second CQI.

In this step, the 4G base station acquires the second SINR according to the second CQI.

In the switching method of the different system base stations, the 4G base station and the 5G base station belong to the same manufacturer, so that information transmission can be realized.

In this step, the 5G base station obtains a location of the first terminal, a first rate, and a first signal to interference plus noise ratio, SINR.

In the step, the 5G base station can acquire the position of the first terminal, the first rate and the first signal-to-interference-plus-noise ratio SINR in real time at a certain frequency; wherein the position of the first terminal may be obtained in real time, for example, by SRS (Synchronous Relay Satellite, synchronized relay satellite); the first rate may be a network speed obtained by the first terminal at the 5G base station; the first signal to interference plus noise ratio SINR may be an SINR obtained at the 5G base station by the first terminal.

In step S620, when the first SINR is less than or equal to the SINR threshold of the 5G base station, the location of the first terminal and the first rate are sent to the 4G base station, so that the 4G base station obtains a second rate of the first terminal according to the location of the first terminal, and obtains a second SINR of the first terminal according to the second rate.

In this step, when the first SINR is less than or equal to the SINR threshold of the 5G base station, the 5G base station transmits the location of the first terminal and the first rate to the 4G base station, so that the 4G base station obtains the second rate of the first terminal according to the location of the first terminal, and obtains the second SINR of the first terminal according to the second rate.

In step S630, when the second rate is greater than the first rate and the second SINR is greater than or equal to the SINR threshold of the 4G base station, a handover notification of the first terminal sent by the 4G base station is received.

In this step, the 5G base station receives a handover notification of the first terminal sent by the 4G base station when the second rate is greater than the first rate and the second SINR is greater than or equal to a SINR threshold of the 4G base station. And when the second rate is greater than the first rate and the second SINR is greater than or equal to the SINR threshold of the 4G base station, proving that the 4G base station can provide qualified network service, and the 5G base station can receive the switching notification of the first terminal sent by the 4G base station.

In step S640, the handover notification is sent to the first terminal, so that the first terminal is handed over to the 4G base station.

In this step, the 5G base station transmits the handover notification to the first terminal to cause the first terminal to handover to the 4G base station.

The switching method of the different system base station shown in fig. 6 obtains the position of the first terminal, the first rate and the first signal-to-interference-plus-noise ratio SINR through the 5G base station; when the first SINR is smaller than or equal to the SINR threshold of the 5G base station, the position and the first rate of the first terminal are sent to the 4G base station, so that the 4G base station obtains a second rate of the first terminal according to the position of the first terminal, and obtains a second SINR of the first terminal according to the second rate; receiving a switching notification of the first terminal sent by the 4G base station when the second rate is greater than the first rate and the second SINR is greater than or equal to an SINR threshold of the 4G base station; and sending the switching notification to the first terminal so that the first terminal is switched to the 4G base station, thereby providing good service experience for the user and ensuring network rate experience of the user.
