Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a system, and a storage medium for configuring a neighboring cell.
Background
Voice over LTE (VoLTE) is a Voice service based on IP Multimedia Subsystem (IMS), which is the final solution for 4G network Voice services. However, in the 4G network construction period, there is inevitably a weak coverage area or even no coverage area, and to ensure the Continuity of the VoLTE Voice Call, Enhanced Single Radio Voice Call Continuity (eSRVCC) may be used to switch the UE from the 4G network to the 3G network or the 2G network. To ensure the handover is successful, the eSRVCC neighbor of the 4G cell needs to be determined.
In the prior art, the eSRVCC neighbor is generally determined based on the longitude and latitude of the base station. The distance between the 4G base station and the 3G base station is calculated based on the longitude and latitude of the two base stations, and the coverage range is counted by combining the distance and the coverage radius to determine the eSRVCC adjacent region.
However, the above method relies on the distance between the base stations as a judgment condition, and needs to calculate based on accurate latitude and longitude information of the base stations, which may cause a deviation of distance calculation when the latitude and longitude information is inaccurate; when there is all difference in coverage between dense urban and suburban areas, then confirmation is needed for different base station densities. In addition, due to the complex wireless environment, if a nearby 3G station is blocked by a high building or other buildings, the strength coverage of the 3G signal is affected. Therefore, the neighbor cell configuration method in the prior art is complex in calculation process, easy to be influenced by the environment and low in accuracy.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
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.
In the following, some terms in the present application are explained to facilitate understanding by those skilled in the art:
1) VoLTE (Voice over Long-Term Evolution Voice bearer) is a high-speed wireless communication standard facing mobile phones and data terminals, and Voice services (control and media level) are transmitted in an LTE data bearer network as data streams without maintaining and depending on a traditional circuit-switched Voice network. VoLTE has voice and data capacity over three times that of 3G UMTS and over six times that of 2G GSM. Because the VoLTE packet header is smaller than the non-optimized VoIP/LTE, it also utilizes bandwidth more efficiently.
2) eSRVCC (Enhanced Single Radio Voice Call Continuity), which can ensure the ongoing Voice Call to be switched to the circuit domain and the Call to be maintained. Therefore, the eRVCC can ensure the continuity of the voice call, reduce the switching delay as much as possible, and control the delay within the range which can be perceived by human beings, so that the ongoing call can not feel the sign of interruption.
3) The CSFB (Circuit Switched Fallback) is suitable for a scene of overlapping coverage of a 2G/3G Circuit domain and a wireless network of LTE, has a simple network structure, does not need to deploy an IMS (IP multimedia subsystem), and can effectively utilize the investment of the existing CS network.
Voice over LTE (VoLTE) is a Voice service based on IP Multimedia Subsystem (IMS), which is the final solution for 4G network Voice services. However, in the 4G network construction period, there is inevitably a weak coverage area or even no coverage area, and to ensure the Continuity of the VoLTE Voice Call, Enhanced Single Radio Voice Call Continuity (eSRVCC) may be used to switch the UE from the 4G network to the 3G network or the 2G network. To ensure the handover is successful, the eSRVCC neighbor of the 4G cell needs to be determined. Here, the method of switching to the 2G network is the same as the method of switching to the 3G network. In the prior art, the eSRVCC neighbor is generally determined based on the longitude and latitude of the base station. The distance between the 4G base station and the 3G base station is calculated based on the longitude and latitude of the two base stations, and the coverage range is counted by combining the distance and the coverage radius to determine the eSRVCC adjacent region. However, the above method relies on the distance between the base stations as a judgment condition, and needs to calculate based on accurate latitude and longitude information of the base stations, which may cause a deviation of distance calculation when the latitude and longitude information is inaccurate; when there is all difference in coverage between dense urban and suburban areas, then confirmation is needed for different base station densities. In addition, due to the complex wireless environment, if a nearby 3G station is blocked by a high building or other buildings, the strength coverage of the 3G signal is affected. Therefore, the neighbor cell configuration method in the prior art is complex in calculation process, easy to be influenced by the environment and low in accuracy.
In view of the above technical problems, the present invention provides a method, which can simplify the configuration process of the neighboring cell, optimize the configuration result of the neighboring cell, and improve the stability of communication. Based on interface signaling data of a mobile communication core network, the invention determines the possibility of switching the eSRVCC of the 4G cell to the peripheral 3G cell by analyzing the user frequency of the user falling back from the 4G network to the 3G network in a short time due to non-CSFB (Circuit Switched Fallback) in the 4G network, and obtains the eSRCC neighbor list of the 4G cell according to the possibility, thereby accurately configuring the eSRCC neighbor of the 4G cell, reducing the switching failure proportion, reducing the call drop probability and improving the user experience. The fallback in the present invention refers to non-CSFB fallback, i.e. the number of CSFB fallback is to be excluded, because CSFB may occur in any coverage area of the 4G cell, and eSRVCC can only be triggered at the coverage edge of the 4G cell, i.e. CSFB occurs in a range much larger than eSRVCC. For the residence policy of multiple networks, the operator preferentially resides in a network of a higher standard, and if a 4G network is already established, the user preferentially resides in the 4G network, that is, when the user is in the 4G network, under the condition of a non-CSFB factor, if the user drops back to the 3G network in a 4G off-line state, which indicates that the coverage of the 4G network is not good, the operator has the non-CSFB drop (hereinafter, the drops refer to non-CSFB drops) from each 4G cell to each 3G cell, and forms a drop matrix of the 4G and 3G cells.
Fig. 1 is a schematic diagram of an application scenario of the present invention, as shown in fig. 1, when there are 4 3G cells covered at the coverage edge of a 4G cell, a fallback matrix between the 4G cell and the 3G cell 1, between the 4G cell and the 3G cell 2, between the 4G cell and the 3G cell 3, between the 4G cell and the 3G cell 4 is formed, and if the number of times of users falling back to the 3G cell 1 is the largest, it indicates that the probability of switching the eSRVCC of the 4G cell to the 3G cell 1 is the largest, and the eSRVCC of the 4G cell should be the largest in the 3G cell 1.
Therefore, the 4G cell eSRVCC neighboring cell can be analyzed and determined by analyzing the number of times that the user falls from each cell of the 4G network to each cell of the 3G network due to non-CSFB reasons due to weak 4G coverage at the edge of each cell of the 4G network. With the frequent application of the mobile internet, the data service interaction of the users is very frequent, and it is found by analyzing the service records (attachment, TAU, service request, etc.) of the users in the S1-MME interface data, 86.3% of the users have service records in the S1-MME within 1 minute, and 93.8% of the users have service records in the S1-MME within 2 minutes, that is, the number of times of users falling back from 4G non-CSFB to 3G in a short time can be obtained by analyzing the service records of the S1-MME interface and Iu interface, and the short time means that the interval from the 4G network to the 3G network of the users cannot be too long, so as to ensure the adjacency between the 4G cell and the 3G cell.
In the specific implementation process, the S1-MME interface record and the Iu-CS interface record may be obtained by the signaling monitoring platform. Then, acquiring all statistical data falling back from the first-type cell to the second-type cell within a preset time period according to the S1-MME interface record and the Iu-CS interface record; screening out data meeting preset conditions from the statistical data as fallback data; wherein the preset conditions comprise: cell fallback due to non-circuit switched fallback CSFB; the fallback data comprises: the cell ID of the first-class cell, the cell ID of the second-class cell, and the number of the fallback from the first-class cell to each second-class cell. Finally, according to the falling times from the first type cells to the second type cells, sequencing the second type cells from high to low; selecting first N second type cells as second type target cells; n is a natural number greater than 1.
The following describes the technical solutions of the present invention and how to solve the above technical problems with specific embodiments. 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. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a neighboring cell configuration method according to an embodiment of the present invention, and as shown in fig. 2, the method in this embodiment may include:
