Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for determining a neighboring cell in a different system.
Background
As communication technology has evolved, 5G networks have been deployed, but there are inevitably weak or no coverage areas. In order to ensure continuity of user services, a weaker area is covered in a 5G network, and a user terminal needs to be switched from the 5G network to a 4G network to perform services. And in the 5G network, a stronger area is covered, and the 4G network is switched back to the 5G network. It is necessary to determine the 4G neighbor cell of the 5G cell or to determine the 5G neighbor cell of the 4G cell before handover to complete the handover of the network.
When determining the 4G adjacent cell of the 5G cell, the user terminal detects the 4G signal intensity after orienting the frequency point of the 4G cell, and then determines that the 4G adjacent cell completes network switching. This way of determining the 4G neighbor cells is inefficient.
And when determining the 5G adjacent cell of the 4G cell, determining the 5G adjacent cell by determining longitude and latitude information of the 5G cell or detecting 5G signal intensity around the 4G cell by adopting a measuring tool. The 5G adjacent cells are determined by determining the longitude and latitude information of the 5G cells, and the accuracy of determining the 5G adjacent cells is low due to the fact that the accuracy of determining the longitude and latitude information of the 5G cells is low. By detecting the 5G signal strength around the 4G cell with the measuring tool, the efficiency of determining the 5G neighboring cell is low, and the accuracy of the determined 5G neighboring cell is low because the indoor area cannot be measured.

These drawings and the written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the disclosed concepts to those skilled in the art by reference to specific embodiments.
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 are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Firstly, explanation is made on nouns according to embodiments of the present invention:
and (3) independent networking: short for the sake of brevity: and SA. NAS signaling used for registration, authentication and other operations between the 5G wireless network element equipment and the core network element equipment is transmitted through a 5G base station, and the 5G equipment can independently work in a networking mode.
And (3) non-independent networking: short for the sake of brevity: NSA. Refers to a network architecture where 5G is attached to a 4G base station to operate. Namely, NAS signaling used for registration, authentication and other operations between the 5G wireless network element equipment and the core network element equipment is transmitted through the 4G base station, and the 5G equipment cannot independently work in a networking mode.
Regardless of the SA or NSA networking mode, the 4G cell needs to configure a 5G neighbor cell. The wireless side triggers the measurement of the user terminal to attach to the 5G network when the user terminal enters the 5G cell. In the initial stage of 5G network construction, the 5G network cannot reach full coverage, weak coverage and even no coverage areas are unavoidable, and in order to ensure the continuity of user service, the user terminal needs to switch the service from the 5G network to the 4G network, so that the 5G cell also needs to be configured with 4G adjacent cells.
At present, when determining the 4G adjacent cells of the 5G cell, after the frequency points of the 4G cell are oriented, the user terminal detects the 4G signal intensity, and determines the 4G cell with the strongest 4G signal intensity as the 4G adjacent cell of the 5G cell. And then the network switching from the 5G cell to the 4G adjacent cell with the strongest signal is completed. Since the ue is required to detect the signal strength of the 4G cell when determining the 4G cell neighbor, this method of determining the 4G neighbor cell is inefficient.
While in determining 5G neighbor cells of a 4G cell, the first way is to determine 5G neighbor cells by determining latitude and longitude information of the 5G cell. Specifically, the distance between the 4G cell and each 5G cell in the preset area is determined according to the longitude and latitude information of the 5G cell and the longitude and latitude information of the 4G cell. The 5G neighbor cells of the 4G cell are determined according to the distance. When the longitude and latitude information of the 5G cell is determined by a positioning mode, the accuracy of the determined longitude and latitude information of the 5G cell is low, and therefore the accuracy of determining the 5G adjacent cell is low.
In determining 5G neighbor cells of a 4G cell, the second way is to determine 5G neighbor cells by detecting 5G signal strengths around the 4G cell using a measurement tool. When the test tool is used to detect the 5G signal intensity around the 4G cell, the test tool needs to be manually taken to move, so that the 5G signal intensity around the 4G cell is detected. The efficiency of determining 5G neighbor cells is low and the accuracy of the determined 5G neighbor cells is low because specific indoor areas, such as hotels, hospitals, etc., cannot be measured.
Therefore, when the technical problems of lower efficiency and lower accuracy of determining the adjacent cells in the prior art are faced, the inventor creatively researches and discovers that when the user terminal performs service, the residence strategies of various networks of different systems reside in the network with higher system preferentially. The 5G network is built, so that the user terminal is allowed to reside in the 5G network preferentially. However, in the period of 5G network construction, the 5G network cannot reach full coverage, and weak coverage or even no coverage area is unavoidable, so that in order to ensure the continuity of user service, the user needs to switch the service from the 5G network to the 4G network. Particularly in an independent networking mode (SA for short) deployed in a 5G network, as shown in fig. 1, a user terminal initiates a voice service in a 5G cell, but EPS voice is required to fall back into a neighboring 4G cell for the voice service. As in fig. 2, the user terminal may drop back to the 4G target cell 1 or the 4G target cell 2 by redirection when initiating voice traffic in the 5G target cell 1. When the user terminal initiates the voice service in the 5G target cell 2, the voice service can fall back to the 4G target cell 2 or the 4G target cell 3 or the 4G target cell 4 through redirection. When the user terminal falls back to a certain 4G target cell from the 5G target cell, the most suitable 4G cell is used for falling back when the user terminal carries out voice service, so that the falling back times corresponding to the 5G target cell and any 4G target cell can truly reflect the proximity relation between the 5G target cell and any 4G target cell. The number of times of reasoning switching from each 4G target cell to any 5G target cell can also be determined through the number of times of fallback between the 5G target cell and any 4G cell. The number of times of switching the voice service back to any 5G target cell is finished, and the inference switching number can reflect the adjacent relation between the 4G target cell and any 5G target cell, so that the determined adjacent cell can be more accurate.
In order to make the determination of the neighboring cells more efficient, the corresponding neighboring cells may be determined according to the fallback situation when the user terminal performs the voice service that has occurred. The fallback situation when the user terminal performs the voice service occurs is embodied in the signaling related information in the related signaling. Therefore, the target signaling related information of initiating the voice service in each 5G target cell and falling back to any 4G target cell can be obtained to determine the falling back times or the reasoning switching times.
According to research discoveries of the inventor, a method for determining adjacent cells in a heterogeneous system is provided. The following describes a network architecture of a neighboring cell determining method in a heterogeneous system according to an embodiment of the present invention. As shown in fig. 3, the network architecture of the method for determining a neighboring cell in the heterogeneous system provided in this embodiment includes: the system comprises an electronic device 1, a signaling monitoring server 2, a 5G target cell network element device 3 and a 4G target cell network element device 4. The electronic device 1 is respectively in communication connection with the signaling monitoring server 2, the 5G target cell network element device 3 and the 4G target cell network element device 4. The electronic device 1 obtains the user traffic signaling in the target area within a preset time range from the signaling monitoring server 2. And processing the user service signaling to obtain target signaling related information that the user terminal initiates the voice service in each 5G target cell and falls back to any one of the 4G target cells. The electronic equipment determines the 4G adjacent cells corresponding to each 5G target cell and the 5G adjacent cells corresponding to each 4G target cell through the adjacent cell determining method in the heterogeneous system. The electronic device 1 sends the 4G neighbor cell information to the corresponding 5G target cell network element device 3, so that the 5G target cell network element device 3 configures the neighbor cell according to the 4G neighbor cell information. The electronic device 1 sends the 5G neighbor cell information to the corresponding 4G target cell network element device 4, so that the 4G target cell network element device 4 configures the neighbor cell according to the 5G neighbor cell information.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Example 1
Fig. 4 is a flowchart of a method for determining a neighboring cell in a different system according to an embodiment of the present application, as shown in fig. 4, where an execution body of the method for determining a neighboring cell in a different system is a neighboring cell determining device in a different system. The neighbor cell determining means in the different system may be located in the electronic device. The method for determining the neighboring cells in the heterogeneous system provided in this embodiment includes the following steps:
step 101, acquiring target signaling related information that a user terminal initiates a voice service in each 5G target cell and falls back to any one 4G target cell in a target area within a preset time range.
The preset time range may be, for example, 1 week, or one month or other suitable time ranges, which is not limited in this embodiment.
The target area may be a city area, a provincial area, a nationwide area, or the like, which is not limited in this embodiment.
In this embodiment, the ue may be distributed in each 5G target cell in the target area, or may be distributed in each 4G target cell. When the networking mode of the 5G network of the 5G target cell is an independent networking mode, when the user terminal in the 5G target cell carries out voice service, the voice service is initiated in the corresponding 5G cell, but EPS voice is required to fall back into the adjacent 4G cell to carry out voice service. So the target signaling related information that the user terminal initiates the voice service in each 5G target cell and falls back into any 4G target cell in the target area is obtained.
The target signaling related information may include: signaling related information corresponding to the 5G network when initiating voice service and signaling related information corresponding to the 4G network when performing voice service in the 4G cell.
The signaling related information corresponding to the 5G network when initiating the voice service may include: signaling start time corresponding to the 5G network, user terminal identification, 5G cell identification information and network type. The signaling related information corresponding to the 4G network when the voice service is performed in the 4G cell may include: signaling start time corresponding to the 4G network, user terminal identification, 4G cell identification information and network type.
The user terminal identifier may be represented by an IMSI (International Mobile Subscriber Identity ) code or other information representing a unique user terminal. The cell identity may be represented by a cell number or other information representing a unique cell. The network type of the 5G cell may be an NR type. The network type of the 4G cell may be EUTRAN type.
Step 102, determining the fallback times of the user terminal for initiating the voice service in each 5G target cell and falling back to any 4G target cell according to the target signaling related information.
In this embodiment, since the target signaling related information includes both signaling related information corresponding to the 5G network when the voice service is initiated and signaling related information corresponding to the 4G network when the voice service is performed in the 4G cell, the number of times that the user terminal initiates the voice service in each 5G target cell and falls back to any one of the 4G target cells can be determined according to the signaling related information corresponding to the 5G network when the voice service is initiated and the signaling related information corresponding to the 4G network when the voice service is performed in the 4G cell.
And step 103, determining the 4G adjacent cells corresponding to each 5G target cell according to the fallback times.
In this embodiment, the number of times of fallback between the 5G target cell and any one of the 4G target cells can truly reflect the proximity relation between the 5G target cell and any one of the 4G target cells, so that the 4G proximity cell corresponding to each 5G target cell can be determined according to the number of times of fallback.
The larger the number of times of fallback between the 5G target cell and any one of the 4G target cells, the larger the probability of determining that the corresponding 4G target cell is a 4G neighboring cell of the 5G target cell. On the contrary, the smaller the number of times of fallback between the 5G target cell and any one of the 4G target cells, the smaller the probability of determining that the corresponding 4G target cell is a 4G neighboring cell of the 5G target cell.
And step 104, determining the reasoning switching times of each 4G target cell to any 5G target cell according to the fallback times.
In this embodiment, after determining the number of times of fallback between each 5G target cell and any one of the 4G target cells, each 4G target cell may be used as a reference to determine the number of times of inferred handover between the 4G target cell and any one of the 5G target cells. The number of times of the reasoning switching is that the voice service is switched back to any 5G target cell. It should be noted that the number of times of the inferred handover from a certain 4G target cell to a certain 5G target cell is equal to the number of times of the fallback from the 5G target cell to the 4G target cell.
And 105, determining 5G adjacent cells corresponding to each 4G target cell according to the reasoning switching times.
In this embodiment, since the number of times of reasoning handover can reflect the number of times of handover back to any 5G target cell after the voice service is performed by voice fallback between the 4G target cell and any 5G target cell, the proximity relation between the 4G target cell and any 5G target cell can also be truly reflected, so that the 5G proximity cell corresponding to each 4G target cell can be determined according to the number of times of reasoning handover.
The larger the number of times of inferred handover between the 4G target cell and any one of the 5G target cells, the larger the probability of determining that the corresponding 5G target cell is a 5G neighboring cell of the 4G target cell. On the contrary, the smaller the number of times of fallback between the 4G target cell and any 5G target cell, the smaller the probability of determining that the corresponding 5G target cell is a 5G neighboring cell of the 4G target cell.
According to the method for determining the adjacent cells in the heterogeneous system, the user terminal initiates the voice service in each 5G target cell in the target area within the preset time range and returns the target signaling related information of any 4G target cell; determining the fallback times of the user terminal initiating the voice service in each 5G target cell and fallback to any 4G target cell according to the target signaling related information; determining 4G adjacent cells corresponding to each 5G target cell according to the fallback times; determining the reasoning switching times of each 4G target cell to any 5G target cell according to the fallback times; and determining 5G adjacent cells corresponding to each 4G target cell according to the reasoning switching times. The number of times of fallback can truly reflect the proximity relation between the 5G target cell and any one of the 4G target cells, and the number of times of reasoning switching can truly reflect the proximity relation between the 4G target cell and any one of the 5G target cells, so that the proximity cell determined according to the number of times of fallback and the number of times of reasoning switching is more accurate. And the obtained target signaling related information is the target signaling related information that the user terminal initiates the voice service in each 5G target cell and falls back to any one 4G target cell in the target area within the preset time range, so that the determining efficiency of determining the adjacent cells is improved when determining the adjacent cells.
Example two
Fig. 5 is a flowchart of a method for determining a neighboring cell in a different system according to another embodiment of the present invention, as shown in fig. 5, where the method for determining a neighboring cell in a different system according to the first embodiment is based on the method for determining a neighboring cell in a different system according to the first embodiment, and further refines steps 101 to 104, and the method for determining a neighboring cell in a different system according to the first embodiment includes the following steps:
step 201, a signaling acquisition request is sent to a signaling monitoring server, where the signaling acquisition request includes preset time range information and target area information.
Specifically, in the present embodiment, user service information records that have occurred in all 5G target cells and all 4G target cells in the target area are stored in advance in the service detection server. The user service information record may include: tracking area update records, service request records, location update records, etc.
Each user traffic information record may be stored using user traffic signaling. For example, the signaling of user service corresponding to the S1-MME interface, the N2 interface and other interfaces can be included.
The S1-MME interface is an interface between a wireless network element device and a core network element device in the 4G network, and the corresponding user service signaling is TAU (Tracking Area Update ) signaling. The N2 interface is an interface between a wireless network element device and a core network element device in the 5G network, and the corresponding user service signaling is PDU (Protocol Data Unit ) resource session modification response signaling.
In this embodiment, the electronic device establishes a communication connection with the signaling monitoring server. And when the requirement of determining the adjacent cell exists, the electronic equipment sends a signaling acquisition request to the signaling monitoring server. The signaling acquisition request comprises preset time range information and target area information. The preset time range information may be the last 1 week, the last 1 month, or the like, for example. The target area information may be, for example, a city area, a nationwide area, or the like.
Step 202, receiving user service signaling matched with preset time range information and target area information sent by a signaling monitoring server.
The user service signaling comprises PDU protocol data unit resource session modification response signaling and TAU tracking area updating signaling.
In this embodiment, the signaling monitoring server analyzes the signaling acquisition request to acquire the PDU resource session modification response signaling and TAU signaling matched with the preset time range information and the target area information. And transmitting the PDU resource session modification response signaling and the TAU signaling to the electronic device.
And 203, processing the user service signaling to obtain the target signaling related information.
As an alternative embodiment, as shown in fig. 6, step 203 includes the steps of:
Step 2031, obtaining a request type corresponding to the PDU resource session modification answer signaling.
In step 2032, the target PDU resource session modification answer signaling with the request type being the voice service type is screened out.
In this embodiment, when the PDU resource session modification response signaling is performed between the wireless network element device and the core network element device, the PDU resource session modification response signaling carries a request reason, where the request reason includes a label of a request type. If the number of the request type is 36, the user terminal initiates the voice service when the PDU resource conversation modification response signaling is determined. And screening the target PDU resource session modification response signaling with the request type being the voice service type from all PDU resource session modification response signaling.
Step 2033, obtaining the first signaling related information in the target PDU resource session modification answer signaling.
As shown in table 1, the first signaling related information includes: signaling start time, user terminal identity and cell identity information (e.g., 5G cell NCI). The first signaling related information may further include: network type.

Step 2034, obtaining initial signaling related information in the TAU signaling.
Wherein the signaling-related information included in each TAU signaling is determined as initial signaling-related information.
The initial signaling related information includes: signaling start time, user terminal identification and cell identification information. The network type may also be included in the initial signaling related information.
In step 2035, the initial signaling related information is filtered to obtain second signaling related information.
As an alternative embodiment, as shown in fig. 7, step 2035 includes the steps of:
step 2035a, ordering the first signaling related information and the initial signaling related information according to the user terminal identifier and the signaling start time.

Optionally, in step 2035b, for each piece of first signaling-related information, it is determined whether there is signaling-related information matching the initial signaling-related information, including the steps of:
step 2035b1, for each piece of first signaling related information, determines whether signaling related information having the same user terminal identifier as the corresponding piece of first signaling related information exists in the initial signaling related information, and the signaling start time is different by less than a preset time threshold, if yes, then step 2035b2 is executed, otherwise step 2035b3 is executed.

Specifically, in this embodiment, after the ue initiates the voice service in the 5G target cell and drops back to a certain 4G target cell, the PDU resource session modification response signaling is different from the signaling start time in the corresponding TAU signaling by a relatively small time. Therefore, the time required for the voice to fall back can be estimated, and then a preset time threshold value, for example, the preset time threshold value is 5 seconds, is determined. Judging whether the signaling related information which is the same as the user terminal identification in the corresponding first signaling related information exists in the initial signaling related information, and determining that the initial signaling related information matched with the first signaling related information exists if the signaling related information which is smaller than the preset time threshold value in the signaling starting time difference exists. And determining that there is initial signaling-related information matching the first signaling-related information as second signaling-related information. If the initial signaling related information does not exist, determining that the initial signaling related information matched with the first signaling related information does not exist, and deleting the first signaling related information and the initial signaling related information.

In step 2036, the first signaling-related information and the second signaling-related information are determined as target signaling-related information.
Step 204, the first signaling related information and the matched second signaling related information are combined into an information pair.
In this embodiment, as shown in table 1 and table 2, the first signaling related information and the matched second signaling related information corresponding to each sequence number form an information pair.
Step 205, determining the corresponding information logarithm of any one 4G target cell from each 5G target cell according to the cell identification information in the target signaling related information; and determining the corresponding information logarithm as the corresponding falling-back times.
In this embodiment, the logarithm of information between each 5G target cell identifier information and any one 4G target cell identifier information is determined, and each logarithm of information indicates that the user terminal initiates a voice service from a corresponding 5G target cell and drops back to the corresponding 4G target cell to perform a voice service once. Wherein the number of fallbacks of 2 5G target cells to 3 4G target cells, respectively, is shown in table 3.
Table 3: schematic table of falling times
Step 206, ordering the corresponding fallback times according to the descending order for each 5G target cell, and determining that the corresponding fallback times are arranged in the first N4G target cells; and determining the 4G target cells with the corresponding fallback times arranged in the first N as corresponding 4G adjacent cells.
In this embodiment, for each 5G target cell, the number of times of fallback to each 4G target cell is sorted in descending order, and the 4G target cells with the number of times of fallback arranged in the first N are obtained. Since the number of times of voice traffic fallback performed between the first N4G target cells and the corresponding 5G target cells is the largest, it is more suitable as a neighboring cell of the corresponding 5G target cells. The 4G target cells, in which the corresponding number of fallbacks is arranged in the first N, are determined as the corresponding 4G neighbor cells.
Wherein N is an integer greater than or equal to 1. If N is 1, 1 4G adjacent cell is determined for each 5G target cell. If N is an integer greater than 1, determining a plurality of 4G cell neighbors for each 5G target cell.
Step 207, determining the reasoning switching times of each 4G target cell to any 5G target cell according to the fallback times.
In this embodiment, after determining the number of times of fallback from each 5G target cell to any one 4G target cell, determining the number of times of inferred handover from each 4G target cell to any one 5G target cell based on each 4G target cell.
As in table 3, the number of inferred handovers from 3 4G target cells to 2 5G target cells is determined. It will be appreciated that the number of fallbacks from a 5G target cell to a 4G target cell is the same as the number of inferred handovers from the 4G target cell to the 5G target cell.
Step 208, ordering the corresponding reasoning switching times according to descending order for each 4G target cell, and determining that the corresponding reasoning switching times are arranged in the first N5G target cells; and determining the 5G target cells with the corresponding reasoning switching times arranged in the first N as corresponding 5G adjacent cells.
In this embodiment, for each 4G target cell, the number of speculative switching times to each 5G target cell is ordered in descending order, and the 5G target cells with the number of speculative switching times arranged in the first N are obtained. Since the inferred switching times can represent the switching times of the user terminal from the 4G cell back to the 5G cell after the voice service is performed, the switching times of the 5G target cells after the voice service is performed between the first N5G target cells and the corresponding 4G target cells are the greatest, so the method is more suitable for serving as the neighboring cells of the corresponding 4G target cells. The 5G target cells, in which the corresponding inferred number of handovers is arranged in the first N, are determined as the corresponding 5G neighbor cells.
Similarly, N is an integer greater than or equal to 1. If N is 1, 1 5G adjacent cell is determined for each 4G target cell. If N is an integer greater than 1, determining a plurality of 5G cell neighbors for each 4G target cell.
Step 209, sending the 4G neighbor cell information to the corresponding 5G target cell network element equipment, so that the 5G target cell network element equipment configures the neighbor cell according to the 4G neighbor cell information; and/or sending the 5G adjacent cell information to the corresponding 4G target cell network element equipment, so that the 4G target cell network element equipment configures the adjacent cell according to the 5G adjacent cell information.
In this embodiment, when the 4G neighbor cell of the 5G target cell needs to be configured, the 4G neighbor cell information is sent to the corresponding 5G target cell network element device. When the 5G adjacent cell of the 4G target cell needs to be configured, the 5G adjacent cell information is sent to the corresponding 4G target cell network element equipment.
It should be noted that, the manner in which the 5G target cell network element device or the 5G target cell network element device configures the neighboring cell is the same as that in the prior art, and will not be described herein again.
In the method for determining the neighboring cells in the heterogeneous system provided by the embodiment, when acquiring the target signaling related information that the user terminal initiates the voice service in each 5G target cell and falls back to any one 4G target cell in the target area within the preset time range, a signaling acquisition request is sent to a signaling monitoring server, wherein the signaling acquisition request comprises the preset time range information and the target area information; receiving user service signaling which is sent by a signaling monitoring server and is matched with the preset time range information and the target area information; and processing the user service signaling to obtain target signaling related information, wherein the signaling monitoring server stores all the signaling generated by the 4G target cells and the 5G target cells in advance, so that the target signaling related information of the user terminal initiating the voice service in each 5G target cell and falling back to any 4G target cell in the target area within the preset time range can be rapidly obtained, and the determination efficiency of the adjacent cells is further improved.
