Network optimization method and device and electronic equipment

Technical Field

The embodiment of the invention relates to the technical field of mobile communication, in particular to a network optimization method, a network optimization device and electronic equipment.

Background

With the development of network technology, the application of 5G (5th Generation Mobile Networks, fifth Generation Mobile communication technology) is becoming more and more popular.

In the prior art, the 5G networks of different operators can be shared, so that the network construction cost can be effectively saved, and the coverage rate of the 5G network can be rapidly improved. In a 5G NSA (Non-standby, Non-independent networking mode) network, a user terminal needs to be connected to a 4G anchor point cell successfully, and then can be connected to a 5G NR (New Radio interface) through an auxiliary node adding process, and during the use process, the user terminal simultaneously maintains dual connection with the 4G anchor point and the 5G NR. In the process, the 4G anchor point base station needs to interact with the 5G NR base station through an X2 interface, and since a protocol of an X2 interface is a private protocol of an equipment manufacturer and protocols of different manufacturers are incompatible, 5G NSA networking can be realized only when the 4G anchor point base station and the 5G anchor point base station are necessarily the same manufacturer. In a co-building sharing scene, due to different equipment manufacturers of base stations of different operators, a scene of flower arrangement of base stations of different operators and different equipment manufacturers inevitably exists in a local area. Under the scene, different operators and different equipment providers have different network conditions, and can provide different services for users, and the anchor point network-residing strategy directly determines whether the users can log in and stably reside in the 5G network, so that the optimization of the anchor point network-residing strategy is of great importance.

However, most of the existing anchor point network-residence strategies adopt a mode of home operator network priority, and although switching of users among different operator networks is greatly reduced, users cannot be guaranteed to use an optimal 5G network, so that transmission rate is affected, and use experience of users is further affected.

However, the existing optimization methods are mainly divided into optimization based on the state of the anchor signal, home operator network priority, and the like, where: the optimization based on the anchor signal state mainly can control the user terminal to reside in the 4G cell with the optimal signal strength according to the condition of the 4G network, and then the 5G network is connected through the auxiliary node adding process, although the continuity of the user on the 4G network is ensured, the signal state of the 5G NR cannot be adjusted in time, and the problems that the user is separated from the 5G, the user uses the weakly covered 5G cell and the like can be caused.

Based on the home operator network priority, the user terminal is controlled to stay on the home network as much as possible and not to be switched to the shared operator network under the condition that the home operator network coverage meets certain conditions, so that although the switching of the user between different operator networks is greatly reduced, the user cannot be guaranteed to use the optimal 5G network, the transmission rate is influenced, and the use experience of the user is further influenced.

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

Fig. 2 is a schematic flow chart of a network optimization method according to an embodiment of the present invention, where the method according to the embodiment may be executed by a base station, as shown in fig. 2, the method according to the embodiment may include:

s201: and acquiring the motion track of the terminal equipment on the 4G anchor point.

In this embodiment, in a 5G NSA network, a terminal device of a user first needs to successfully connect to a 4G anchor cell before connecting to a 5G NR through an adding process of an auxiliary node, and keeps dual connections with the 4G anchor and the 5G NR during a use process. In the process, the 4G anchor base station needs to interact with the 5G NR base station through an X2 interface. Since the protocol of the X2 interface is a proprietary protocol of the equipment manufacturer and the protocols of different manufacturers are incompatible, the 4G and 5G base stations must be the same manufacturer to enable 5G NSA networking. In a co-building sharing scene, due to different equipment manufacturers of different operator base stations, a scene that base stations of different operators and different equipment manufacturers are arranged in a local area inevitably exists, and therefore, a motion track of the terminal equipment on the 4G anchor point can be obtained firstly.

Furthermore, the motion track of the terminal equipment on the 4G anchor point can be obtained by sequentially recording the resident 4G cell, the 4G signal intensity, the resident starting time and the resident ending time of the terminal equipment and inquiring longitude and latitude data corresponding to the 4G cell in the mobile network engineering parameter table. The longitude and latitude data corresponding to the 4G cell can be obtained by inquiring in a preset mobile network engineering parameter table.

Table 1 is an information table of the terminal device residing in the 4G cell, which may specifically include a name of the residing 4G cell, a residence start time, a residence end time, a 4G signal strength, and a longitude and a latitude of the 4G cell.

The 4G signal strength in table 1 is the average signal strength detected by the terminal in the residence time, and is reported to the base station side through the measurement report, and the operator to which the cell belongs may also be determined by the name of the residence cell.

S202: and determining the motion state of the terminal equipment according to the motion trail.

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

Obtaining the current time T to T-2T according to the motion track _th The cell where the terminal device resides and longitude and latitude information within a time period, wherein T represents the current time, and T represents the latitude and longitude information _th Representing a time threshold, said terminal device being in the range from T to T-T _th The set of cells residing in the time period is C _C At T-T _th To T-2T _th The set of cells residing in the time period is C _B 。

If it is

And R (C) _C )＜R _th And determining that the motion state of the terminal equipment is a static state.

Wherein the cell set C _C And C _B The format of (d) may be:

C _C two, (4G) cell 1, 4G cell 2, };

C _B say } for {4G cell 1, 4G cell 2, 4G cell 3.

T _th Representing a time threshold, R _th The radius threshold is not specifically limited in the present invention, and can be set according to actual requirements. Exemplary, T _th Can be set to 5 minutes, R _th Can be set to 200 meters, this means that within the last 5 minutes, the terminal equipmentThe radius of the distribution range of the used base stations is not more than 200 meters.

In addition, the static state in the invention does not mean that the terminal device has no movement at all, but the movement range is very limited within a certain time, and long-distance movement does not occur. That is, in the static state according to the present invention, there may be a change in the user-camping cell due to small-range movement of the terminal, sudden change in the radio signal, and the like.

S203: and if the motion state of the terminal equipment is a static state, reversely matching a first target anchor point corresponding to the terminal equipment based on the 5G NR coverage conditions of different operators and different equipment manufacturers, and controlling the terminal equipment to move to the position of the first target anchor point, thereby realizing the continuous login of the 5G network.

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

and sending a signal strength measurement request to a terminal device, wherein the signal strength measurement request is used for indicating the terminal device to detect and report the NR signal strengths of a plurality of operators to obtain signal strength sets corresponding to the plurality of operators.

And selecting the target operator corresponding to the target signal with the strongest signal from the signal strength set.

And searching for the 4G cell corresponding to the target operator in a preset cell set, and extracting signal strength to obtain an anchor point signal strength set, wherein the preset cell set is a cell set in which the terminal equipment resides within a preset time period.

Specifically, for a terminal device in a static state, a measurement control of 5G NR is issued, the terminal device is required to detect and report NR signal strengths RSRP of multiple operators, and multiple operator signal strength sets are formed, where a format of an operator signal strength set S may be:

here, in the set S, the signal strengths of a plurality of NR cells of the same operator may be included. In this step, the network side needs to ask the terminal device to measure all the 5G NR frequency points of the candidate operator, the 5G NR measurement report reported by the terminal device includes the physical cell identity PCI and the signal strength, and the base station can distinguish different cells of different operators according to the reported PCI. After receiving the NR signal strength set S reported by the terminal device, the base station may select the target operator corresponding to the signal with the strongest signal, and set C with the target operator corresponding to the signal with the strongest signal _C The 4G cell of the target operator is searched, the signal strength is extracted, and an anchor point signal strength set M is formed, wherein the set format can be as follows:

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

and then, a first target anchor point matched with the terminal equipment can be determined from the anchor point signal strength set according to a preset anchor point selection rule.

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

if the anchor signal strength set meets the condition:

selecting the network corresponding to the target operator as the optimal resident network, wherein M represents the anchor point signal intensity set, and M is _th Which represents the threshold of the anchor signal strength,

representing any first target anchor signal strength and m1 representing the first target anchor signal strength.

And sending a preset optimal operator anchor point resident control parameter to the terminal equipment so as to enable the terminal equipment to reside on a 4G anchor point cell of a target operator corresponding to the optimal resident network.

If the anchor signal strength set does not satisfy the condition:

and sending preset anchor point residing control parameters to enable the terminal equipment to preferentially reside in a 4G anchor point (namely, a first target anchor point) cell of a target operator corresponding to the optimal residing network.

Specifically, in the set M, if all anchor signals of the operator are stronger than threshold signals, the operator network is selected as the best residing network, where M is _th The signal strength threshold of the anchor point is represented and is the minimum signal strength value allowed to reside by the anchor point, and under a specific network environment, the situation of residing instability can occur after the signal is lower than the threshold value.

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

if the current terminal equipment resides in the 4G anchor point cell of the target operator corresponding to the optimal residing network, sending an optimal operator measurement control request to the current terminal equipment, and deleting the measurement of the anchor points of other operators and the 5G NR. And re-sending the measurement control request of the optimal operator to the current terminal equipment so that the terminal equipment selects a 5G cell in which a signal can reside and which can meet the service requirement in the signal fluctuation process.

And if the current terminal equipment does not reside in the 4G anchor point cell of the target operator corresponding to the optimal resident network, sending a specific measurement control request to the current terminal equipment so as to enable the current terminal equipment to measure the conditions met by the optimal operator network again. And acquiring conditions met by the best operator network measured by the current terminal equipment, and controlling the current terminal equipment to be switched to the best operator anchor point corresponding to the conditions met by the best operator network through switching and redirecting instructions. And logging in 5G through a preset auxiliary station adding process, re-executing the steps of sending a best operator measurement control request to the current terminal equipment, deleting the measurement of other operator anchor points and 5G NR and the subsequent steps if the current terminal equipment is resided in the 4G anchor point cell of the target operator corresponding to the best resident network.

Specifically, even if the same operator is used, the problem of rate reduction also exists in the switching process of the switching between two cells with the same frequency point, so that if the current terminal equipment is already resident on the best operator network (namely, the current terminal equipment is already resident on the 4G anchor point cell of the target operator corresponding to the best resident network), the network side can issue measurement control to delete the measurement of anchor points and 5G NRs of other operators, the signal frequency points adopted by different operators are different, and the terminal needs extra time overhead for measuring the signals of different frequency points, so that the method can avoid the terminal from frequently initiating the inter-frequency measurement to bring extra time delay on the service, and meanwhile, the terminal is ensured not to be resident on the other operator networks. Secondly, the best operator measurement control is issued again, and the current terminal equipment is controlled to select the signal in the signal fluctuation process5G small-sized mobile terminal capable of residing and meeting business requirements Zone(s)And the 4G anchor point meets the resident requirement, so that the problems of rate reduction and the like caused by the change of a 5G cell or anchor point are reduced.

If the current terminal device does not reside on the best operator network (i.e. does not reside on the 4G anchor point cell of the target operator corresponding to the best resident network), the base station can issue specific measurement control for the current terminal device, the current terminal device reports to the base station after measuring the best operator network again and meeting the conditions, then the base station controls the terminal to be switched to the best operator anchor point through switching and redirecting instructions, 5G is logged in through the auxiliary station adding process, and then the current terminal device can execute the relevant process according to the process of 'the current terminal is already resident on the best operator network'.

The target operator corresponding to the optimal residing network is an operator determined by the principle of meeting the lowest residing threshold and the service requirement.

S204: and if the motion state of the terminal equipment is a mobile state, controlling the terminal equipment to dynamically detect the coverage conditions of 4G anchor points and 5G NR of different operators, and realizing the continuous login of the 5G network of the terminal equipment according to the first target anchor point.

In this embodiment, if the motion state of the terminal device is a mobile state, controlling the terminal device to dynamically detect the coverage conditions of the 4G anchor point and the 5G NR of different operators, and dynamically selecting the second target anchor point according to the service requirement of the terminal device may specifically include:

and if the motion state of the terminal equipment is a mobile state, sending a control parameter measurement request to the terminal equipment, wherein the control parameter measurement request comprises preset measurement parameters and is used for indicating the terminal equipment to detect and report the 4G anchor point signal strength and the 5G NR signal strength of different operators in real time.

And acquiring the 4G anchor point signal strength and the 5G NR signal strength of different operators, which are detected by the terminal equipment in real time, and acquiring the 5G adjacent area signal strength corresponding to the current resident network operator.

And judging the signal intensity of the 5G adjacent cell corresponding to the current resident network operator according to a preset service judgment rule to obtain a judgment result.

Further, the method for determining the signal strength of the 5G neighboring cell corresponding to the current resident network operator according to the preset service determination rule to obtain a determination result may specifically include:

and acquiring the current service requirement value of the terminal equipment.

then it is confirmedAnd determining the judgment result as the anchor point selection control process of the operator to be entered.

If the expression is not satisfied:

Specifically, the calculation of p(s) may be obtained based on network statistics, that is, statistics of the rate, delay, or jitter that can be achieved under different signal strengths s in the current network. It should be noted that the signal strength meeting the service requirement may not necessarily meet the terminal device residence condition, and the minimum signal strength s for terminal device residence _th Depending on the actual network environment, interference from surrounding sites, network load, etc. all affect s _th 。

The decision result has two kinds, one is to select the control flow for the anchor point of the operator to be entered, and the other is to change the flow for the network operator to be entered.

Further, if the decision result is that the operator anchor point is to be entered into the selection control process, dynamically selecting a second target anchor point corresponding to the terminal device according to the decision result, which may specifically include:

according to the expression:

representing any second target anchor signal strength, and m2 represents the second target anchor signal strength.

If not satisfied with

Specifically, if the expression is satisfied:

if the intensity of all anchor electric signals is smaller than the minimum stay intensity, the anchor points of the operator are considered to be not in accordance with the stay condition, and the judgment result can be updated to be the network operator change flow to be entered, and the network operator change flow is entered.
