Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a diagram illustrating an evaluation method for network capacity expansion according to an embodiment of the present invention. The evaluation method for network capacity expansion may be executed by a server, a processor, and the like, and the server is taken as an example below. As shown in fig. 1, the evaluation method for network capacity expansion includes the following steps.

S110: and determining the limit number of users required to be carried by a first wireless access network of the vehicle route according to the limit number of passengers accommodated by the vehicle, wherein the first wireless access network is a special wireless access network of the vehicle.

Specifically, the server may directly determine the limit number of passengers accommodated by the vehicle as the limit number of users required to be carried by the first radio access network of the vehicle route, or the server may determine the limit number of users required to be carried by the first radio access network of the vehicle route by multiplying the limit number of passengers accommodated by a certain ratio and then increasing the certain number of users.

It should be understood that the vehicle may be a train, a high-speed rail, a ship, an airplane, etc., as long as it can carry passengers and can move, and the type of the vehicle is not particularly limited by the embodiment of the present invention.

The limit number of passengers accommodated by the vehicle may be the number of passengers that can be carried by the vehicle under the limit condition, specifically, the limit number of passengers accommodated by the vehicle may be determined based on the number of seats in the vehicle, such as an airplane, or may be determined based on the number of seats in the vehicle and then overlapping a certain number of passengers, such as the number of seats on a train or a high-speed train and/or the number of crew members on the high-speed train, or may be determined based on the structure and materials of the vehicle, such as the number of passengers that can be carried by the train, the high-speed train, a ship, or the like, and how to determine the limit number of passengers accommodated by the vehicle is not particularly limited in the embodiment of the present invention.

The limit number of passengers accommodated by the vehicle may be stored in the server, or may be called by the server from a device such as a cloud, or may be obtained according to an input of an operator.

The first radio access network may be a mobile network, a communication network, a telecommunication network, or the like, and the first radio access network may only include a Time Division Duplex (TDD) mode, may also only include a Frequency Division Duplex (FDD) mode, may also be a combination mode of the TDD mode and the FDD mode, and may also be other modes, which is not specifically limited in this embodiment of the present invention.

S120: the number of active connections users of the first radio access network is determined.

Specifically, the server may determine the number of effective connection users of the first Radio access network according to performance parameters of the first Radio access network, such as a frequency band, and the like, may also directly call data in other devices, such as a cloud, and the like, to determine the number of effective connection users of the first Radio access network, and may also determine the number of effective connection users of the first Radio access network by analyzing the number of Radio Resource Control (RRC) connection users and a Physical Resource Block (PRB) utilization rate.

It should be understood that the number of the users connected to the first wireless access network is the maximum number of users under the condition that the network of each user connected to the first wireless access network is smooth, and when the number of users connected to the first wireless access network exceeds the number of the users connected to the first wireless access network, the users perceive the network deterioration, which affects the experience effects of the users in watching videos or playing games and the like by using the network.

S130: and evaluating the number of users to be met by the capacity expansion of the first wireless access network according to the limit number of users and the number of effective connection users.

In some embodiments, the server may subtract the number of effective connection users from the limit number of users to obtain an estimated number of users to be satisfied for capacity expansion of the first wireless access network. In other embodiments, the server may obtain the number of users to be satisfied by the capacity expansion of the first wireless access network evaluated in combination with the limit number of users, the number of effective connection users, and the other number of users. The embodiment of the invention does not specifically limit how to evaluate the number of users to be met by the capacity expansion of the first wireless access network according to the limit number of users and the number of effective connection users.

Fig. 2 is a diagram illustrating an evaluation method for network capacity expansion according to another embodiment of the present invention. The embodiment shown in fig. 2 is an example of the embodiment shown in fig. 1. As shown in fig. 2, the difference from the embodiment shown in fig. 1 is that the vehicle is a train, steps S111 to S114 correspond to step S110 in the embodiment shown in fig. 1, and steps S121 to S122 correspond to step S120 in the embodiment shown in fig. 1.

S111: the limit number of passengers accommodated by the train is determined based on the situation that the train is full of passengers.

Specifically, the server may determine limit data for the passengers accommodated by the train based on the number of passengers when the train is fully loaded with passengers. In some embodiments, the situation where the train is fully loaded with passengers during busy hours such as spring festival or national day may be that the number of tickets sold for the train includes the sum of the number of seats and stops and the number of people on the train, and the server may determine the limit number of passengers accommodated by the train based on the sum of the number of tickets sold for the train and the number of people on the train; in other embodiments, the condition that the train is fully loaded with passengers when the train is idle, such as a working day, may be seat numbers of the train, and the server may determine the limit number of passengers accommodated in the train based on the seat numbers of the train, which is not specifically limited in the embodiment of the present invention.

It should be understood that the train may be a train, a light rail, a high-speed rail, a maglev train, or the like, and the embodiment of the present invention is not particularly limited thereto. The condition that the train is full of passengers may be set before network capacity expansion evaluation, may also be automatically identified, and may also be obtained by performing big data analysis on historical data by using an artificial intelligence technology, which is not specifically limited in the embodiment of the present invention.

S112: user penetration rate possessed by an operator of a first radio access network is acquired.

In some embodiments, the server may obtain the user permeability of the operator of the first radio access network from the self storage module, the server may also call the user permeability of the operator of the first radio access network from other devices such as a cloud, and the server may further receive an input of an operator to obtain the user permeability of the operator of the first radio access network.

It should be understood that the operator of the first radio access network may be mobile, connected, or telecom, and the embodiment of the present invention is not limited thereto. The user penetration rate of the operator of the first radio access network may be fixed or may be variable, which is not specifically limited in the embodiment of the present invention. For example, when the operator of the first radio access network is mobile, the user penetration rate of the mobile is 70% according to the existing big data analysis, and the user penetration rate of the mobile can be changed along with the development of the society and the change of living habits of people.

S113: the number of first users is obtained by multiplying the limit number by the user permeability.

In some embodiments, the server multiplies the limit number by the user penetration rate, thereby obtaining a number of first users; in other embodiments, the device or module other than the server multiplies the limit number by the user permeability to obtain a product number, and the server invokes the product number and confirms that the product number is the number of the first user, so as to obtain the number of the first user.

S114: and determining the limit number of the users required to be carried by the first wireless access network of the vehicle route according to the number of the first users.

In some embodiments, the server may directly determine the number of first users as an extreme number of users that the first radio access network of the vehicle approach needs to carry; in other embodiments, the server may also determine the limit number of users that the first radio access network of the vehicle access needs to carry in combination with the number of the first users and other users, such as the number of users that the second radio access network (e.g., a public network) invades the first radio access network.

For steps S111-S114, for example, when the number of tickets sold for a single train is 900 and the number of staff on the train is 100, the server determines that the limit number of passengers accommodated by the train is 1000 based on the condition that the train is full of passengers. When the server obtains that the user penetration rate of the operator of the first radio access network is 80%, the number of the first users is obtained by multiplying the limit number by the user penetration rate, wherein the number of the first users is 1000 × 80% — 800. The further server may determine an extreme number of users 800 to be carried by the first radio access network for the vehicle approach based on the number of first users 800.

S121: and constructing a first relation graph between the number of first RRC connection users in the first wireless access network and the utilization rate of the first PRB.

In some embodiments, the server may invoke a large number of first radio resource control RRC connection user numbers and corresponding first physical resource block PRB utilization rates from a network management data platform of the first radio access network, and construct a first relationship diagram between the first radio resource control RRC connection user numbers and the first physical resource block PRB utilization rates in the first radio access network according to the invoked data. In other embodiments, the first relationship graph may also be obtained by analyzing a network management data platform or other platforms or devices, and the server may also directly invoke and construct the first relationship graph. The embodiment of the present invention does not specifically limit how to construct the first relational diagram.

It should be understood that the first relation graph may be a scatter diagram, a graph, a bar chart, and the like, which is not specifically limited in this embodiment of the present invention.

S122: and determining the number of RRC connection users corresponding to the first position according to the first position at the sudden reduction position of the slope of the curve in the first relation graph, wherein the number of the RRC connection users corresponding to the first position is the number of effective connection users.

In some embodiments, when the first relation graph is a graph, the slope of the curve may be calculated, a first position (e.g., an inflection position) where the slope of the curve is suddenly decreased is found, and the number of RRC connection users corresponding to the first position is determined according to the first position, that is, the number of effective connection users; or determining a first position at which the slope of the curve is suddenly reduced according to experience, and determining the number of RRC connection users corresponding to the first position according to the first position, namely the number of effective connection users; the range of the number of first RRC connection users in the maximum range of the slope change of the curve can be determined, and the average number of the RRC connection users in the range of the number of the first RRC connection users is obtained, namely the number of effective connection users. In other embodiments, when the first relationship diagram is a scatter diagram, the first location may be a range of a first PRB utilization rate when it is determined that the first PRB utilization rate obviously increases and starts to slow as the number of first RRC connected users increases according to the scatter diagram, and the range of the first PRB utilization rate is determined to correspond to the range of the number of first RRC connected users, and an average number of RRC connected users in the range of the number of first RRC connected users is determined, which is the number of RRC connected users corresponding to the first location; the first position may also be a range of the first PRB utilization rate when the first PRB utilization rate obviously increases and starts to slow down as the number of first RRC connected users is increased according to the scatter diagram, an average PRB utilization rate within the range of the first PRB utilization rate is obtained, and the number of RRC connected users corresponding to the average PRB utilization rate is further determined from the first relation diagram, that is, the number of RRC connected users corresponding to the first position. In still other embodiments, when the first relationship graph is a scatter graph, the scatter graph may be further converted into a graph, and other steps may be similar to the graph. The embodiment of the present invention does not specifically limit how to determine the number of RRC connected users corresponding to the first location according to the first location where the slope of the curve in the first relation graph decreases.

It should be understood that the first position may refer to a point on the curve, or may refer to a range on the curve, which is not particularly limited by the embodiment of the present invention.

For example, the server determines that the number of RRC connection users corresponding to the first location is 510 according to the first location where the slope of the curve in the first relation graph decreases suddenly.

For example, the server evaluates that the number of users to be satisfied for capacity expansion of the first wireless access network is 800-510-290 according to the limit number of users 800 and the number of active connection users 510.

According to the technical scheme provided by the embodiment of the invention, the limit number of passengers accommodated by the train is determined in combination with the condition that the train is fully loaded with passengers in the steps S111-S114, and the limit number of users required to be borne by the first wireless access network of the transportation means approach is determined in combination with the user permeability of the operator of the first wireless access network, so that users not using the first wireless access network in the train are eliminated, the determination of the limit number of users is more accurate, and the utilization rate of the network is effectively improved. In addition, in steps S121 to S122, the number of effective connection users of the first radio access network is determined by combining the number of first RRC connection users in the first radio access network and the first PRB utilization rate, so that the determination of the number of effective connection users of the first radio access network is more accurate. The embodiment of the invention can accurately determine the limit number of users required to be borne by the first wireless access network and the effective connection number of users of the first wireless access network, so that the capacity required to be expanded by the first wireless access network can be more accurately evaluated, and the expanded first wireless access network can be ensured to have high-quality network signals and sufficient network capacity.

Fig. 3A is a diagram illustrating an evaluation method for network capacity expansion according to another embodiment of the present invention. The embodiment shown in fig. 3A is an example of the embodiment shown in fig. 2. In the embodiment shown in fig. 3A, the train takes a high-speed rail as an example, and the first radio access network takes a mobile 4G network as an example, as shown in fig. 3A, the difference from the embodiment shown in fig. 2 is that the method for evaluating network capacity expansion may further include step S140, and step S1141 corresponds to step S114 in the embodiment shown in fig. 2. In addition, when the first radio access network, such as the mobile 4G network, includes the TDD mode and the FDD mode, steps S1211-S1212 correspond to step S121 in the embodiment shown in fig. 2, and steps S1221-S1223 correspond to step S122 in the embodiment shown in fig. 2.

S140: the number of second users establishing a connection with the first radio access network is estimated, wherein the second users are users to which the second radio access network belongs.

Specifically, the server may directly estimate the number of second users establishing connection with the first radio access network according to the proportion of the existing second radio access network invading the first radio access network; the server can also estimate the number of second users establishing connection with the first wireless access network according to the total number of users belonging to the second wireless access network; the server may also directly invoke the number of the second users establishing connection with the first wireless access network from the network management data platform of the first wireless access network, so as to estimate the number of the second users, which is not specifically limited in the embodiment of the present invention.

For example, when a train runs through a certain logical station of a first wireless access network in Jiangsu province, users belonging to a second wireless access network near the certain logical station invade the first wireless access network, wherein the number of the second users establishing connection with the first wireless access network is about 100 according to big data statistics, and the number of the second users establishing connection with the first wireless access network is estimated to be 100 by a server.

It should be understood that the number of the second users may be fixed during the whole train traveling process, or may vary according to different areas where the train travels, and this is not particularly limited in the embodiment of the present invention.

S111: the limit number of passengers accommodated by the train is determined based on the situation that the train is full of passengers. The train may be a high-speed rail.

It should be appreciated that the server may also perform the ganged grouping of the cars of the high-speed train, such as replacing one or more of the two-seat cars with galleys with the normal two-seat cars to determine the limit number of passengers accommodated by the high-speed train, or replacing one or more of the one-seat cars with the normal two-seat cars to determine the limit number of passengers accommodated by the high-speed train, considering that there are also crews, drivers, crews, technicians, chefs, etc., and passengers purchased by station tickets, which is not particularly limited by the embodiments of the present invention.

S1141: and determining the limit number of the users required to be carried by the first wireless access network of the vehicle route according to the number of the first users and the number of the second users.

Specifically, the server may directly add the number of the first users and the number of the second users to determine the number of the limit users required to be loaded by the first radio access network of the vehicle route, or may determine the number of the limit users required to be loaded by the first radio access network of the vehicle route by combining other data except the number of the first users and the number of the second users, which is not specifically limited in the embodiment of the present invention.

For example, in step S111-S1141, the total seat number of a certain high-speed train is 1114, and considering that there are train managers, drivers, crews, technicians, chefs and other staff of the high-speed train and passengers purchased by station tickets, the server performs reconnection grouping on the cars of the high-speed train, for example, a second-class car with a kitchen is replaced by a common second-class car, and the server determines that the limit number of passengers accommodated in the high-speed train is 1200 based on the cars of the reconnection grouping. The server obtains a user penetration rate of 70% that the operator of the first radio access network has, and the number of first users 840 is obtained by multiplying the limit number 1200 by the user penetration rate of 70%. When the server estimates that the number of the second users establishing connection with the first radio access network is 100 in step S140, the server determines the limited number 940 of the users required to be carried by the first radio access network of the vehicle route according to the number 840 of the first users and the number 100 of the second users in step S1141.

S1211: and constructing a second relation graph between the number of second RRC connection users and the utilization rate of the second PRB in the TDD mode.

S1212: and constructing a third relation graph of the third RRC connection user number and the third PRB utilization rate in the FDD mode.

It should be understood that the second relation graph and the third relation graph may be a scatter diagram, a graph, a bar chart, and the like, which is not specifically limited in this embodiment of the present invention. For example, a second relationship diagram may be as shown in FIG. 3B and a third relationship diagram may be as shown in FIG. 3C.

S1221: and determining the number of RRC connection users corresponding to the second position according to the second position at the sudden slope reduction position of the curve in the second relation graph.

It should be understood that, as shown in fig. 3B, the second position may be at position a or position B, which is not specifically limited in this embodiment of the present invention.

S1222: and determining the number of RRC connection users corresponding to the third position according to the third position at the sudden slope reduction position of the curve in the third relation graph.

It should be understood that the second position and the third position may be determined in a manner similar to the first position, and thus, the description thereof is omitted. As shown in fig. 3C, the second position may be at position C or at position D, which is not specifically limited in this embodiment of the present invention.

S1223: and obtaining the number of effective connection users by overlapping the number of RRC connection users corresponding to the second position with the number of RRC connection users corresponding to the third position.

For example, in steps S1221 to S1223, the server may determine the number of RRC connection users corresponding to the second location to be 190 according to the second location where the slope of the curve in the second relationship diagram decreases, and the server may determine the number of RRC connection users corresponding to the third location to be 280 according to the third location where the slope of the curve in the third relationship diagram decreases. The server obtains the number of effective connection users 470 by superimposing the number 190 of RRC connection users corresponding to the second location and the number 280 of RRC connection users corresponding to the third location.

It should be understood that the number of RRC connection users corresponding to the second location may be greater than, less than, or equal to the number of RRC connection users corresponding to the third location, which is not specifically limited in the embodiment of the present invention.

For example, the server evaluates the number of users 470 to be satisfied for the first wireless access network expansion based on the limit number of users 940 and the number of active connection users 470.

According to the technical scheme provided by the embodiment of the invention, the number of the second users connected with the first wireless access network is estimated, so that the condition that the users belonging to the second wireless access network invade the first wireless access network is fully considered in the process of estimating the number of the users to be met by the capacity expansion of the first wireless access network, and further, when the capacity expansion is carried out based on the number of the users to be met by the capacity expansion of the first wireless access network, the first wireless access network can have high-quality network signals and sufficient network capacity under the condition that the users belonging to the second wireless access network invade the first wireless access network. In addition, when the first radio access network comprises a plurality of modes such as a TDD mode and an FDD mode, a relation graph between the number of RRC connection users and the PRB utilization rate is respectively constructed for the TDD mode and the FDD mode, so that the difference of the number of effective connection users which can be borne in different modes is fully considered, and the accurate evaluation of the capacity required to be expanded by the first radio access network is further realized.

As shown in fig. 4, the difference from the embodiment shown in fig. 3 is that steps S141-S142 correspond to step S140 in the embodiment shown in fig. 3A, and S11411 corresponds to step S1141 in the embodiment shown in fig. 3A.

S141: and determining the proportion of the users to which the second wireless access network belongs to all the users connected with the first wireless access network when the users are detained in the first wireless access network.

For example, it can be known from the existing big data statistics that when a train travels through any logical station of a first radio access network in Shandong province, a user belonging to a second radio access network in any logical station intrudes into the first radio access network, wherein the user belonging to the second radio access network intruding into Shandong province occupies about 9.5% of all users connected to the first radio access network when staying in the first radio access network.

It should be understood that the proportion of the user to which the second radio access network belongs to all the users connected to the first radio access network when the user is staying in the first radio access network may be determined according to practical situations, and is not limited to 9.5%, and may also be 5%, 15%, 20%, and the like, and the numerical value of the proportion is not specifically limited in the embodiment of the present invention.

S142: and calculating the number of the second users according to the number and the proportion of the first users.

For example, when the number of first users is 840 and the ratio is 9.5%, the server calculates the number of second users 840/(100% -9.5%) x 9.5% — 88 according to the number of first users and the ratio.

S11411: and adding the number of the first users and the number of the second users to obtain the limit user number.

For example, when the number of the first users is 840 and the number of the second users is 88, the server adds the number of the first users and the number of the second users to obtain 928 as the limit user number 840+ 88.

For example, when the limit number of users is 928 and the number of users with effective connections is 470, the server evaluates that the number of users to be satisfied by the capacity expansion of the first wireless access network is 928-470-458 according to the limit number of users and the number of users with effective connections.

According to the technical scheme provided by the embodiment of the invention, the number of the second users is determined by combining the proportion of the users belonging to the second wireless access network to all the users connected with the first wireless access network when the users belonging to the second wireless access network stay in the first wireless access network, so that the condition that the users belonging to the second wireless access network invade the first wireless access network is fully considered in the process of evaluating the number of the users to be met by the capacity expansion of the first wireless access network, and further, when the capacity expansion is carried out based on the number of the users to be met by the evaluation of the first wireless access network, the first wireless access network can have high-quality network signals and sufficient network capacity under the condition that the users belonging to the second wireless access network invade the first wireless access network.
