Due to the diversification of the service requirements of users, operators need to dynamically adjust network slices in real time according to the change of the service requirements, so as to meet different service requirements of users. When a network is actually deployed, it is difficult to perform real-time adjustment of resources according to the service requirements of a single user, and although a 5G network can meet the higher network speed requirements of the user, it is difficult to ensure that the user can successfully register in a target cell during network switching in busy time periods and hot spots, resulting in a low switching success rate. Therefore, the application provides a mobile network switching method for improving the success rate of user switching.
In a first aspect, an embodiment of the present application provides a mobile network handover method, which is applicable to a network side.
Fig. 1 is a flowchart of a mobile network handover method according to an embodiment of the present application. As shown in fig. 1, the mobile network handover method includes:
Wherein the handover request includes a slice identifier supported by the terminal.
In some embodiments, the terminal initiates a handover request to the current base station in a hot spot area or a busy period. The hot spot area refers to a region where the user terminals are more dense, and the busy time period refers to a time period where the user terminals use the mobile network more densely.
For example, the hotspot area may be the vicinity of a shopping mall, especially a shopping mall high-sales activity, where the number of terminals is large. The busy time interval is the business time of a shopping mall, when the shopping mall makes sales promotion activities and is in the business time, the types of user services are various, and the requirements of performance, time delay, speed and the like required by each service are different, so that the conditions of network interruption or switching failure and the like are easily caused because a target network cannot be quickly selected in the network switching process of the terminal.
And 102, acquiring all candidate base stations matched with the slice identifier and corresponding access frequency points based on the slice identifier supported by the terminal.
Wherein, the slice (NS) is a virtual Network structure which is logically independent through the combination of Network functions. The Identity (ID) of the slice may be referred to simply as the slice ID. The application scenario of slice ID may include: when the terminal accesses the network, the initial access message carries the slice ID, and the network side performs authentication based on the slice ID and other information to determine whether the terminal is allowed to access. The terminal can determine the slice of the network slice which can be accessed according to the obtained corresponding slice ID.
In practical applications, one terminal may simultaneously connect with a plurality of different network slices and participate in related slicing services. For example, a terminal connects slice a, slice B and slice C simultaneously, and although the terminal can connect multiple slices simultaneously, in the control plane, the terminal has only one rrc connection and signaling connection between network elements, different slices share the same signaling radio bearer over the air, and interface control codes between network elements still share the same rlc connection bearer.
When the terminal is in a busy period and/or a hot spot area and a target network needs to be reselected, the terminal carries a slice identifier supported by the terminal in a switching request sent by the current base station, and the current base station obtains a selected base station based on the slice identifier supported by the terminal.
In some embodiments, the selected base stations are all base stations capable of supporting the slice required by the terminal. And the current base station acquires all candidate base stations and corresponding access frequency points which are the same as the slice identifiers based on the slice identifiers supported by the terminal.
And 103, sequencing the candidate base stations based on the switching success rates of all the candidate base stations in the current time period to obtain a sequencing result.
The switching success rate is a success rate of the current base station counting the switching of the terminal connected with the current base station to other base stations in the current time period, and the current time period may be any time period, for example, 5 minutes or 10 minutes from the current time.
In some embodiments, the current base station counts the total number of the switching requests initiated by all terminals connected to the current base station in the current time period and the total number of the successful switching, and then obtains the switching success rate based on the total number of the successful switching and the total number of the switching requests initiated, and obtains the occupation conditions of the slice network resources corresponding to different frequency points.
And sequencing different base stations based on the switching success rate to obtain a sequencing result. In the sequencing result, the higher the switching success rate is, the higher the base station rank is, the higher the success rate of the frequency point and the slice of the same base station is, the higher the rank is, namely, the forward sequence sequencing is. In another embodiment, the sorting results may also be reversed, that is, the higher the handover success rate, the later the base station rank, the higher the success rate of the frequency point and the slice of the same base station, the later the rank, that is, the reverse sorting.
And 104, selecting the candidate base station with the first rank from the ranking results as a target base station, and sending the target base station to the terminal so that the terminal can be switched to the target base station.
In some embodiments, the candidate base station with the first rank is selected from the ranking results as the target base station, and for the same candidate base station, the candidate base station with the higher success rate of frequency point and slice is selected as the target slice, and the target base station is sent to the terminal, so that the terminal can be switched to the target base station.
It is easy to understand that when the sequencing result is in reverse sequence, the current base station selects the candidate base station with the last ranking as the target base station, and for the same candidate base station, selects the candidate base station with higher success rate of frequency point and slice as the target slice, and sends the target base station to the terminal for the terminal to switch to the target base station.
The mobile network switching method provided by the embodiment can improve the switching success rate of the terminal in the busy period or the moving process of the hot spot area, thereby improving the user experience.
Fig. 2 is a flowchart of step 102 in the embodiment of the present application. As shown in fig. 2, step 102 includes:
In some embodiments, the current base station extracts the service identifier of the terminal, the supported slice identifier, the identifier of the target base station to which the terminal is switched, and the corresponding access frequency point based on the terminal identifiers of all the terminals which are successfully switched in the current time period, and forms a first data table.
The terminal identifier is an identifier for identifying the terminal identity, and the terminal identifier may be a SIM card number or the like. The service identifier is an identifier for identifying the service type of the terminal, and the service identifier can be a voice identifier, a download identifier, a web browsing identifier and the like. The slice identifier can be obtained by an identifier pre-configured on the universal integrated circuit card, and can also be obtained by configuration in a downloading mode.
In some embodiments, the first data table obtained by the current base station includes service identifiers and slice identifiers of all terminals accessing the current base station, and the terminal switches the corresponding relationship between the successfully-switched target base station identifier and the corresponding access frequency point.
And the second data table is obtained after the first data table is analyzed, and comprises the corresponding relation among the target base station identification, the access frequency point, the switching success rate and the slice type.
After receiving a switching request sent by a terminal, the current base station searches a second data table according to the service requirement of the terminal, and obtains a slice data list which is the same as a slice identifier supported by the terminal, wherein the slice data list comprises all target base stations supporting slices required by the terminal, corresponding frequency points and a switching success rate.
In step 103, the current base station generates one or more candidate base stations according to the matching condition of the target base station and the priority order, and instructs the terminal to perform handover according to the priority order.
In some embodiments, before step 102, further comprising: counting the switching success rate of the terminal in the current time period; judging whether the switching success rate is lower than a switching threshold value; and when the switching success rate is lower than the switching threshold value, a first data table is formed. The handover threshold is a threshold preset by the current base station.
In some embodiments, the current base station counts the handover success rates of all the accessed terminals in the current time period, then determines whether the handover success rate is lower than a handover threshold, and if the handover success rate is lower than the handover threshold, determines by combining the reason of the handover failure. And if the reason of the switching failure is that the terminal is in a hot spot area and in a busy period, triggering the current base station to generate a second data table.
When the mobile terminal is in a busy time period or a hot spot area and a target network needs to be reselected, the base station analyzes the switching success rate of the current network in different time periods, if the switching success rate of the current time period is lower than a set value, other terminal switching success records of the same type as the current terminal slice are obtained, and the corresponding target base station identification and the corresponding frequency point are obtained through the analysis of the records and are used as an optimal target base station to indicate the current terminal to switch.
The mobile network switching method provided by the embodiment of the application receives a switching request initiated by a terminal; the switching request comprises a slice identifier supported by the terminal; acquiring all candidate base stations matched with the slice identifications and corresponding access frequency points based on the slice identifications supported by the terminal; sequencing the candidate base stations based on the switching success rate of all the candidate base stations in the current time period to obtain a sequencing result; and selecting the candidate base station with the first rank from the ranking results as a target base station, and sending the target base station to the terminal so as to switch the terminal to the target base station. The method can improve the success rate of switching the terminal in the busy time period or the moving process of the hot spot area, thereby improving the experience of the user.
In a second aspect, an embodiment of the present application provides a mobile network handover method, which is used for a terminal. Fig. 3 is a flowchart of a handover method for a mobile network according to an embodiment of the present application. As shown in fig. 3, the mobile network handover method includes:
Wherein the handover request includes a slice identifier supported by the terminal.
In some embodiments, the terminal initiates a handover request to the current base station in a hot spot area or a busy period. The hot spot area refers to a region where the user terminals are more dense, and the busy time period refers to a time period where the user terminals use the mobile network more densely.
For example, the hotspot area may be the vicinity of a shopping mall, especially a shopping mall high-sales activity, where the number of terminals is large. The busy time interval is the business time of a shopping mall, when the shopping mall makes sales promotion activities and is in the business time, the types of user services are various, and the requirements of performance, time delay, speed and the like required by each service are different, so that the conditions of network interruption or switching failure and the like are easily caused because a target network cannot be quickly selected in the network switching process of the terminal.
And the target base station obtains a candidate base station based on the slice identifier supported by the terminal by the current base station, and switches to power selection based on the candidate base station in the current time interval.
In practical applications, one terminal may simultaneously connect with a plurality of different network slices and participate in related slicing services. For example, a terminal connects slice a, slice B and slice C simultaneously, and although the terminal can connect multiple slices simultaneously, in the control plane, the terminal has only one rrc connection and signaling connection between network elements, different slices share the same signaling radio bearer over the air, and interface control codes between network elements still share the same rlc connection bearer.
When the terminal is in a busy period and/or a hot spot area and a target network needs to be reselected, the terminal carries a slice identifier supported by the terminal in a switching request sent by the current base station, and the current base station obtains a selected base station based on the slice identifier supported by the terminal.
In some embodiments, the selected base stations are all base stations capable of supporting the slice required by the terminal. And the current base station acquires all candidate base stations and corresponding access frequency points which are the same as the slice identifiers based on the slice identifiers supported by the terminal.
And based on the terminal identifications of all the terminals which are successfully switched in the current time period, extracting the service identification, the supported slice identification, the switched target base station identification and the corresponding access frequency point of the terminal to form a first data table. Analyzing the first data table to obtain a second data table; and the second data table comprises the corresponding relation of the target base station identification, the access frequency point, the switching success rate and the slice type.
In some embodiments, the current base station extracts the service identifier of the terminal, the supported slice identifier, the identifier of the target base station to which the terminal is switched, and the corresponding access frequency point based on the terminal identifiers of all the terminals which are successfully switched in the current time period, and forms a first data table.
The terminal identifier is an identifier for identifying the terminal identity, and the terminal identifier may be a SIM card number or the like. The service identifier is an identifier for identifying the service type of the terminal, and the service identifier can be a voice identifier, a download identifier, a web browsing identifier and the like. The slice identifier can be obtained by an identifier pre-configured on the universal integrated circuit card, and can also be obtained by configuration in a downloading mode.
In some embodiments, the first data table obtained by the current base station includes service identifiers and slice identifiers of all terminals accessing the current base station, and the terminal switches the corresponding relationship between the successfully-switched target base station identifier and the corresponding access frequency point.
In some embodiments, the second data table is obtained after analyzing the first data table, and the second data table includes a corresponding relationship between a target base station identifier, an access frequency point, a handover success rate, and a slice type.
In some embodiments, the current base station counts the total number of the switching requests initiated by all terminals connected to the current base station in the current time period and the total number of the successful switching, and then obtains the switching success rate based on the total number of the successful switching and the total number of the switching requests initiated, and obtains the occupation conditions of the slice network resources corresponding to different frequency points.
And sequencing different base stations based on the switching success rate to obtain a sequencing result. In the sequencing result, the higher the switching success rate is, the higher the base station rank is, the higher the success rate of the frequency point and the slice of the same base station is, the higher the rank is, namely, the forward sequence sequencing is. In another embodiment, the sorting results may also be reversed, that is, the higher the handover success rate, the later the base station rank, the higher the success rate of the frequency point and the slice of the same base station, the later the rank, that is, the reverse sorting.
In some embodiments, the candidate base station with the first rank is selected from the ranking results as the target base station, and for the same candidate base station, the candidate base station with the higher success rate of frequency point and slice is selected as the target slice, and the target base station is sent to the terminal, so that the terminal can be switched to the target base station.
It is easy to understand that when the sequencing result is in reverse sequence, the current base station selects the candidate base station with the last ranking as the target base station, and for the same candidate base station, selects the candidate base station with higher success rate of frequency point and slice as the target slice, and sends the target base station to the terminal for the terminal to switch to the target base station.
Step 303, an access request is sent to the target base station to access the target base station and the corresponding access frequency point.
In some embodiments, before step 301, further comprising:
judging whether the terminal is in a hot spot area or a busy period; and when the terminal is in a hot spot area and/or a busy time period, the switching request sent to the current base station contains the slice identifier supported by the terminal.
And when the mobile terminal is in a busy period or a hot spot area and needs to reselect a target network, the terminal sends a switching request to the base station. The base station analyzes the switching success rate of the current network at different time intervals, if the switching success rate of the current time interval is lower than a set value, other terminal switching success records of the same type as the current terminal slice are obtained, and the corresponding target base station identification and the corresponding frequency point are obtained through analyzing the records and are used as the optimal target base station to indicate the current terminal to switch.
