Description

A method and device for enabling eSRVCC function

technical field

The present application relates to the field of wireless communication technologies, and in particular, to a method and apparatus for enabling the eSRVCC function.

Background technique

High-definition calling (Voice over LTE, VoLTE) is the final solution for the fourth generation communication technology (4th generation, 4G) network voice service. During the construction period of the 4G network, the 4G network has not achieved full coverage, and there will inevitably be weak coverage or even no coverage. In the coverage area, to ensure the continuity of VoLTE voice calls, operators need to enable the Enhanced Single Radio Voice Call Continuity (eSRVCC) function. It enables the user terminal to switch from the 4G network to the third generation communication technology (3th generation, 3G) network or the second generation communication technology (2th generation, 2G) network. The cost of the eSRVCC function of the network is a large investment. How to accurately analyze the demanded cells and save the investment cost while ensuring the continuity of the call is a technical problem that needs to be solved urgently.

Taking switching to a 3G network as an example, some operators currently have two methods to enable the eSRVCC function for 3G cells: one is to use the network-wide method without distinguishing between different cells. Obviously, the investment cost of this method is too high. The other is to evaluate the 4G network coverage of the 3G cell coverage area according to the 4G measurement report (MR) data. For 3G cells with poor 4G network coverage, turn on 3G cells with poor 4G network coverage, but not for 3G cells with good 4G network coverage. This method requires a large amount of MR data, and some operators do not collect data in some areas, so it is difficult to implement comprehensively, and the coverage area of 3G cells cannot be accurately delineated (delineated by latitude and longitude) based on the weak coverage area of MR data, so the accuracy is not high. .

In the description of this application, unless otherwise stated, the meaning of "plurality" refers to two or more.

Circuit Switched Fallback (CSFB) is a method that allows User Equipment (UE) in an Evolved Packet System (EPS) network to fall back to the CS domain and borrow the infrastructure of the CS domain to provide technology for voice services.

Enhanced Single Radio Voice Call Continuity (eSRVCC) is used to achieve seamless handover between VoLTE calls and existing 2G or 3G networks, enabling user terminals to switch from Long Term Evolution (LTE) networks to 2G or 3G network to switch to ensure the continuation of voice calls.

At present, eSRVCC generally occurs when the network coverage is weak or the interference is severe, while CSFB occurs everywhere within the coverage of the LTE network. This application is mainly used to study the situation of users falling back due to non-CSFB. Weak coverage is used as an example to illustrate Sexual description. Referring to FIG. 1, serial numbers 1, 2, and 3 are respectively different cells of the first network type, and serial number 4 is a cell of the second network type. The network standard of the first network type is higher than that of the second network type. The terminal preferentially camps on a network type of a higher standard, and when the signal coverage of the cell of the first network type is poor, the user terminal will fall back from the cell of the first network type to the cell of the second network type. For example, if the 4G network has been built, the user terminal is given priority to stay on the 4G network. If the user terminal is disconnected from the 4G network and falls back to the 3G network due to non-CSFB factors, it means that the 4G network coverage here is not good. The more times the user terminals fall back to the 3G cell, the more times the 4G cell eSRVCC needs to be handed over to the 3G cell, and the stronger the necessity for 3G cell 1 to enable eSRVCC.

The method for enabling the eSRVCC function provided by the embodiment of the present application obtains the minimum interval time of network type fallback by analyzing user signaling record information, and further counts the fallback times of the target area within a preset time period. When the fallback times exceeds a preset threshold value, the eSRVCC function is enabled in the target area. The purpose of saving investment costs is achieved by analyzing the necessity of enabling the eSRVCC function.

An embodiment of the present application provides a method for enabling the eSRVCC function. As shown in FIG. 2 , the method may include S101-S104:

S101. Acquire user signaling record information.

First, obtain the user signaling record information through the signaling monitoring platform deployed by the operator. Specifically, obtain the user signaling record information of at least two interfaces through the signaling monitoring platform, and the at least two interfaces include the S1-MME interface and the Iu-MME interface. One of CS interface and A interface. The S1-MME interface is used to obtain user signaling record information whose network type is 4G. If there is no S1-MME interface, the SGs interface can also be used instead. The difference is that the information capacity of the SGs interface is smaller than that of the S1-MME interface. When the data sample size is lower, the SGs interface can completely replace the S1-MME interface. The Iu-CS interface is used to obtain user signaling record information whose network type is 3G, and the A interface is used to obtain user signaling record information whose network type is 2G.

Under normal circumstances, the network type will fall back from 4G to 3G, or from 4G to 2G. When the research content is 4G falling back to 3G, the user signaling record information of the S1-MME interface and Iu-CS interface is obtained. When falling back to 2G for 4G, obtain the user signaling record information of the S1-MME interface and the A interface, and the user signaling record information includes cell identification (such as cell number), user identification (such as International Mobile Subscriber Identity (International Mobile SubscriberIdentification) Number, IMSI code)), network type and time. Refer to Table 1 to Table 2, wherein Table 1 is the record of the S1-MME interface, and Table 2 is the record of the Iu-CS interface.

S102. Determine, according to the user signaling record information, the minimum interval time after the user equipment falls back from the cell of the first network type to the cell of the second network type.

After the user signaling record information is acquired through step S101, the minimum interval time after the user terminal falls back from the first network type cell to the second network type cell is determined according to the user signaling record information. Specifically, the user signaling record information includes the time when the user terminal is in different network types. For example, at 11:02:10 am on October 9, 2018, and the network type of the user terminal is 4G, the user signaling record information The network type is 4G, and the corresponding time is 11:02:10 am on October 9, 2018. Obtain the first network type and corresponding time and the second network type and corresponding time of the user terminal in adjacent time, and then calculate the minimum interval time after falling back from the first network type to the second network type. For example, the first network type is 4G, the second network type is 3G, the time when the network type of the user terminal in the S1-MME interface record is 4G is 11:02:10 am on October 9, 2018, and the Iu-CS interface record The time when the network type of the user terminal is 3G includes 11:02:30 am on October 9, 2018 and 11:04:20 am on October 9, 2018, so the user terminal falls back from the first network type cell to the second network The minimum interval for type cells is 20 seconds. In conjunction with table 1-table 2, one by one analysis obtains table 3, with reference to table 3, table 3 is the comparison table that obtains the time, community and network type of current record and previous record by user and time after table 1 and table 2 are merged, According to the table, the fallback situation of the user terminal between the 4G network and the 3G network can be obtained. This embodiment mainly focuses on the situation where the first network type is a 4G network and the second network type is a 3G network, that is, the previous network type is a 4G network and the current network type is a 3G network.

table 3

S103. If the minimum interval time for the user terminal to fall back from the cell of the first network type to the cell of the second network type is less than the first preset threshold value, add 1 to the count times of the cell of the second network type.

The minimum interval time for the user terminal to fall back from the first network type cell to the second network type cell is obtained through step S102, if the minimum interval time for the user terminal to fall back from the first network type cell to the second network type cell is less than the first preset If the threshold value is set, the number of counts of the cell of the second network type is incremented by 1. The first preset threshold value can be adjusted according to the actual situation. The smaller the first preset threshold value is, the more accurate the final result is. In this embodiment, the first preset threshold value is 1 minute. That is, when the time for the user terminal to fall back from the cell of the first network type to the cell of the second network type is less than 1 minute, the non-CSFB fallback of the cell of the second network type is recorded once, and the count is incremented by 1.

S104. If the counted times of the cell of the second network type exceeds a second preset threshold value within a preset time period, enable the eSRVCC function in the cell of the second network type.

The non-CSFB fallback times of the cells of the second network type are counted through step S103. The larger the counted times, the greater the possibility that the eSRVCC of the surrounding 4G cells will be switched to the cells of the second network type, that is, the greater the possibility of 3G cells, and the counted times can be defined as ON. The necessity index of the eSRVCC function. If the number of counts of the cell of the second network type exceeds the second preset threshold within the preset time period, the eSRVCC function is enabled. In practical applications, when the necessity index reaches the value of enabling the eSRVCC function, it depends on the actual situation. For example, when the preset necessity index is 800 and the preset time period is one week, the second network type cell will be within one week. The eSRVCC function is turned on after falling back more than 800 times. Referring to Table 4, it is a statistical table of the eSRVCC function necessity index of some cells in a city within a week. In the table, the necessity indices of cell 460014227558881, cell 460014226231913, cell 460014225811327, and cell 460014224822431 are all higher than 800, so all four cells can enable the eSRVCC function.
