In the prior art, 5G networks of different operators can be co-constructed and shared, which can effectively save network construction costs and rapidly improve the coverage of 5G networks. In the 5G NSA (Non-Standalone, non-independent networking mode) network, the user terminal needs to successfully connect to the 4G anchor cell before connecting to the 5G NR (New Radio, new air interface) through the process of adding a secondary node, and using In the process, the dual connection with 4G anchor point and 5G NR is maintained at the same time. In this process, the 4G anchor base station needs to interact with the 5G NR base station through the X2 interface. Since the protocol of the X2 interface is the private agreement of the equipment manufacturer, the protocols of different manufacturers are not compatible, so the 4G and 5G base stations must be of the same manufacturer. Only under these circumstances can 5G NSA access the network. In the co-construction and sharing scenario, because the equipment manufacturers of different operators' base stations are different, there will inevitably be flower arrangements of base stations of different operators and different equipment manufacturers in local areas.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The terms "first", "second", "third", "fourth", etc. (if present) in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to Describe a particular order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are also capable of encompassing other sequential instances than those illustrated or described. Furthermore, the terms "comprising" and "having" and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those expressly listed Rather, those steps or units may include other steps or units not expressly listed or inherent to these processes, methods, products or devices.

In the prior art, 5G networks of different operators can be co-constructed and shared, which can effectively save network construction costs and rapidly improve the coverage of 5G networks. In the 5G NSA (Non-Standalone, non-independent networking mode) network, the user terminal needs to successfully connect to the 4G anchor cell before connecting to the 5G NR (New Radio, new air interface) through the process of adding a secondary node, and using In the process, the dual connection with 4G anchor point and 5G NR is maintained at the same time. In this process, the 4G anchor base station needs to interact with the 5G NR base station through the X2 interface. Since the protocol of the X2 interface is the private agreement of the equipment manufacturer, the protocols of different manufacturers are not compatible, so the 4G and 5G base stations must be of the same manufacturer. Only under these circumstances can 5G NSA access the network. In the co-construction and sharing scenario, due to the different equipment manufacturers of the base stations of different operators, there will inevitably be scenes of flower arrangement of base stations of different operators and different equipment manufacturers in the local area. In this scenario, the network conditions of different operators and equipment vendors are different, and the ability to provide services to users is different, and the anchor point's network strategy directly determines whether users can log in and stably reside on the 5G network. Therefore, anchor points The optimization of the point-and-click network strategy is very important.

However, the existing optimization methods are mainly divided into the optimization based on the signal state of the anchor point and the priority of the network of the home operator. Among them, the optimization based on the signal state of the anchor point can mainly control the signal strength of the user terminal according to the conditions of the 4G network. The optimal 4G cell camps on, and then connects to the 5G network through the process of adding secondary nodes. Although the continuity of the user on the 4G network is guaranteed, the signal status of 5G NR cannot be adjusted in time, which will cause the user to leave 5G. Problems such as users using 5G cells with weak coverage.

On the other hand, based on the network priority of the home operator, the user terminal can be controlled to stay on the home network as much as possible and not switch to the shared operator network when the coverage of the home operator network meets certain conditions. Switching between networks, but users cannot be guaranteed to use the optimal 5G network, which affects the transmission rate, which in turn affects the user experience.

Based on the above problems, the present application comprehensively considers the activity state of the terminal device and the structure of the network, so as to not only improve the stability of the terminal device's 5G network residency and the continuity of the connection in the flower arrangement scene, but also improve the transmission The speed guarantees the technical effect of the user's experience.

As shown in Figure 1, gNB is a base station of the 5G system, a cell controlled by gNB is an NR cell, and ng-eNB is an enhanced LTE base station accessing a 5G core network , the cell controlled by the ng-eNB is an LTE cell. The gNBs are interconnected through the Xn interface, the gNB and the ng-eNB are connected through the Xn interface, and the ng-eNBs are interconnected through the Xn interface.

The technical solutions of the present invention will be described in detail below with specific examples. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 2 is a schematic flowchart of a network optimization method according to an embodiment of the present invention. The method in this embodiment may be executed by a base station. As shown in FIG. 2 , the method in this embodiment may include:

S201: Acquire the movement track of the terminal device on the 4G anchor point.

In this embodiment, under the 5G NSA network, the user's terminal device needs to successfully connect to the 4G anchor cell first, and then can connect to the 5G NR through the process of adding a secondary node, and maintains the connection with the 4G anchor and 5G during the use process. Dual connection for NR. In the process, the 4G anchor base station needs to interact with the 5G NR base station through the X2 interface. Since the protocol of the X2 interface is the private protocol of the equipment manufacturer, and the protocols of different manufacturers are not compatible, the 4G and 5G base stations must be from the same manufacturer to be able to access the 5G NSA network. In the co-construction and sharing scenario, due to the different equipment manufacturers of the base stations of different operators, there will inevitably be flower arrangements of base stations of different operators and different equipment manufacturers in the local area. Therefore, you can first obtain the terminal equipment on the 4G anchor point. movement trajectory.

Further, the terminal equipment can be obtained by sequentially recording the 4G cell where the terminal equipment resides, the 4G signal strength, the starting time and the stopping time, and querying the latitude and longitude data corresponding to the 4G cell in the mobile network engineering parameter table. Motion track on the 4G anchor point. The latitude and longitude data corresponding to the 4G cell can be obtained by querying the preset mobile network engineering parameter table.

Table 1 is the information table of the terminal equipment camping on the 4G cell, which may specifically include the name of the camping 4G cell, the camping start time, the camping end time, the 4G signal strength, and the longitude and latitude of the 4G cell.

Table 1 Information table of terminal equipment camping on 4G cells

Among them, the 4G signal strength in Table 1 is the average signal strength detected by the terminal during the dwell time, which is reported to the base station side through the measurement report, and the operator to which the cell belongs can also be determined through the name of the dwelling cell.

S202: Determine the motion state of the terminal device according to the motion track.

In this embodiment, the motion state of the terminal device can include two types, one is a static state, and the other is a moving state, and the motion state of the terminal device can be determined according to the motion track of the terminal device, which can be specifically:

Acquire the cell where the terminal device resides and the latitude and longitude information in the time period from the current time t to t-2*T _th according to the motion trajectory, where t represents the current time, T _th represents the time threshold, and the terminal device is in The set of cells that reside in the time period from t to tT _th is C _C , and the set of cells that reside in the time period from tT _th to t-2*T _th is C _B .

且R(C_C)＜R_th，则确定所述终端设备的运动状态为静止状态。like

and R(C _C )<R _th , it is determined that the motion state of the terminal device is a static state.

Otherwise, the motion state of the terminal device is determined to be a mobile state, wherein R _th represents a radius threshold, and R(C _C ) represents the radius of the smallest circumscribed circle that can geographically cover all cells in the cell set C.

The formats of the cell sets C _C and C _B may be:

C _C = {4G cell 1, 4G cell 2, ...};

_CB = {4G cell 1, 4G cell 2, 4G cell 3, . . . }.

T _th represents a time threshold, and R _th represents a radius threshold, which are not specifically limited in the present invention, and can be set according to actual needs. Exemplarily, T _th can be set to 5 minutes, and R _th can be set to 200 meters, which means that in the past 5 minutes, the base station distribution radius used by the terminal device does not exceed 200 meters.

In addition, the stationary state described in the present invention does not mean that the terminal device does not move at all, but that the range of motion is very limited within a certain period of time, and no long-distance movement occurs. That is, in the static state described in the present invention, there may still be a change in the cell where the user resides due to the small-scale movement of the terminal, the sudden change of the wireless signal, and the like.

S203: If the motion state of the terminal device is a static state, reversely match the first target anchor point corresponding to the terminal device based on the 5G NR coverage of different operators and different device manufacturers, and control the terminal device to move to the first target The location of the anchor point is moved, thereby realizing the continuous login of the 5G network.

In this embodiment, if the motion state of the terminal device is a static state, the first target anchor point corresponding to the terminal device is reversely matched based on the 5G NR coverage of different operators and different device manufacturers, which may specifically include:

A signal strength measurement request is sent to the terminal device, wherein the signal strength measurement request is used to instruct the terminal device to detect and report the NR signal strengths of multiple operators to obtain a set of signal strengths corresponding to the multiple operators.

The target operator corresponding to the target signal with the strongest signal is selected from the signal strength set.

Find the 4G cell corresponding to the target operator in the preset cell set, and extract the signal strength to obtain the anchor point signal strength set, wherein the preset cell set is the terminal equipment in the preset time period. Set of remaining cells.

A first target anchor point matching the terminal device is determined from the anchor point signal strength set according to a preset anchor point selection rule.

Specifically, for a terminal device in a stationary state, the measurement control of 5G NR is issued, and the terminal device is required to detect and report the NR signal strength RSRP of multiple operators, and form a set of multiple operators' signal strength, the operator's signal strength The format of the set S can be:

Wherein, the set S may include the signal strengths of multiple NR cells of the same operator. In this step, the network side needs to ask the terminal device to measure all 5G NR frequency points of the candidate operator, and the 5G NR measurement report reported by the terminal device includes the physical cell identifier PCI and signal strength. different cells of the operator. After receiving the NR signal strength set S reported by the terminal equipment, the base station can select the target operator corresponding to the signal with the strongest signal, and find the 4G cell of the target operator in the set C _C , extract the signal strength, and form an anchor point The signal strength set M, the set format can be:

M={m ₁ =-85dBm, m ₂ =-91dBm, m ₃ =-99dBm,...}.

Then, the first target anchor point matching the terminal device may be determined from the set of anchor point signal strengths according to the preset anchor point selection rule.

Further, determining a first target anchor point matching the terminal device from the anchor point signal strength set according to a preset anchor point selection rule, which may specifically include:

则选取所述目标运营商对应的网络为最佳驻留网络，其中，M表示锚点信号强度集合，m_th表示锚点信号强度门限，

表示任意第一目标锚点信号强度，m1表示第一目标锚点信号强度。If the anchor signal strength set satisfies the conditions:

Then, the network corresponding to the target operator is selected as the best resident network, where M represents the anchor signal strength set, m _th represents the anchor signal strength threshold,

represents the signal strength of any first target anchor point, and m1 represents the signal strength of the first target anchor point.

Sending preset optimal operator anchor camping control parameters to the terminal equipment, so that the terminal equipment camps on the 4G anchor cell of the target operator corresponding to the optimal camping network.

则发送预设的锚点驻留控制参数，以使所述终端设备优先驻留在最佳驻留网络对应的目标运营商的4G锚点(即第一目标锚点)小区上。If the anchor signal strength set does not meet the conditions:

Then, preset anchor camping control parameters are sent, so that the terminal device preferentially camps on the 4G anchor (ie the first target anchor) cell of the target operator corresponding to the best camping network.

Specifically, in the set M, all the anchor signals of the operator are stronger than the threshold signal, then the operator network is selected as the best resident network, where m _th represents the anchor signal strength threshold, which is the anchor allowable The minimum signal strength value for dwelling. In a specific network environment, after the signal is lower than the threshold value, the dwelling instability will occur.

In addition, the base station sends preset optimal operator anchor camping control parameters to the terminal device, so that the terminal device camps on the 4G anchor cell of the target operator corresponding to the optimal camping network , can be divided into two cases, which can include:

If the current terminal device has already camped on the 4G anchor cell of the target operator corresponding to the best camping network, send the best operator measurement control request to the current terminal device, and delete other operator anchor points and 5G NR Measurement. The optimal operator measurement control request is resent to the current terminal device, so that the terminal device selects a 5G cell where the signal can reside and which can meet service requirements during the signal fluctuation process.

If the current terminal equipment does not camp on the 4G anchor cell of the target operator corresponding to the best camping network, send a specific measurement control request to the current terminal equipment, so that the current terminal equipment measures again Conditions met by the best carrier networks. Obtain the conditions met by the best operator network measured by the current terminal device, and control the current terminal device to switch to the best operator anchor corresponding to the conditions met by the best operator network through handover and redirection instructions Point. Log in to 5G through the preset secondary station addition process, and re-execute the above if the current terminal device has already camped on the 4G anchor cell of the target operator corresponding to the best camping network, send the best operator measurement control Request to the current terminal device and delete other operator anchors and 5G NR measurements and subsequent steps.

Specifically, even if it is the same operator and the handover between two cells with the same frequency point, there will be a problem of rate drop during the handover process. (that is, it has already camped on the 4G anchor cell of the target operator corresponding to the best camping network), the network side can issue measurement control, delete the measurement of other operators' anchor points and 5G NR, which are used by different operators. The signal frequency points of the different frequency points are different, and the terminal needs extra time to measure the signals of different frequency points. Therefore, this method can avoid the terminal from frequently initiating inter-frequency measurement, which brings extra delay in the service, and also ensures that the terminal will not camp on the on other carrier networks. Secondly, the optimal operator measurement control is re-issued to control the current terminal equipment to select a 5G cell where the signal can reside and meet the service requirements during the signal fluctuation process, and the 4G anchor point meets the residency requirements, reducing the Problems such as rate drop caused by 5G cell or anchor point change.

If the current terminal device does not camp on the best operator network (that is, does not camp on the 4G anchor cell of the target operator corresponding to the best camp network), the base station can issue a specific measurement control for the current terminal device , the current terminal device measures the optimal operator network again and reports to the base station after meeting the conditions. Then, the base station controls the terminal to switch to the optimal operator anchor point through handover and redirection instructions, and logs in to 5G through the auxiliary station addition process, and then the current The terminal device can perform the relevant procedures according to the procedure of "the current terminal has been residing on the network of the best operator".

Among them, the target operator corresponding to the best resident network is an operator determined on the principle of satisfying the lowest resident threshold and service requirements.

S204: If the motion state of the terminal device is a mobile state, control the terminal device to dynamically detect the coverage of 4G anchor points and 5G NR of different operators, and realize the continuous login of the terminal device to the 5G network according to the first target anchor point.
