Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.
In a public-private network convergence scenario, a public network is generally positioned as a supplement to a private network to make up for the shortage of private network coverage. The communication network in which the terminal should camp is typically selected by determining the degree of coverage of the network signal. If the signal coverage of the private network is poor, the terminal selects to reside in the public network; and when the private network signal coverage is better, the terminal resides in the private network. But does not consider the network load degree of the public network or the private network by judging the coverage degree of the signals of the public network or the private network. When the private network signal is better than the public network and the terminal switches, if the network load capacity of the current private network is not considered, the service quality of the terminal will be obviously reduced under the high-load network. Similarly, the situation is also applicable to switching the private network to the public network.
In view of the above problems, an embodiment of the present invention provides a public/private network handover method to achieve a technical effect of reasonably selecting a residential network by judging a network load on the basis of meeting coverage, as shown in fig. 1, the detailed steps are as follows:
and S11, receiving the cell ID and the base station resource utilization rate periodically sent by each base station of the public network cell and the private network cell.
In this step, each base station of the public network cell and the private network cell periodically sends the ID of the cell where the base station is located and the corresponding base station resource utilization rate to the server side. Each base station of the public network cell counts the terminals using the frequency spectrum of the base station, obtains the resource utilization rate of the base station, and reports the resource utilization rate and the ID of the corresponding cell to the server side. Meanwhile, each base station periodically uploads the resource utilization rate of the base station and the corresponding cell ID so as to update the information of each base station on the server side in real time.
And S12, detecting the high load cell of which the base station resource utilization rate is higher than the preset threshold value in the public network cell and the private network cell.
In this step, the resource utilization rate uploaded by each base station in the public network cell and the private network cell includes, but is not limited to, the RB utilization rate and the CCE utilization rate. The RB utilization rate is obtained by collecting and counting the number of all used RBs and the total number of RBs in a period transmitted by each base station, and using the number of used RBs/the total number of RBs. Similarly, the number of all the used CCEs and the total number of the CCEs in the period transmitted by each base station are counted, and the CCE utilization rate is obtained through the CCE use data/the total number of the CCEs.
Besides the above conditions for evaluating the resource utilization rate of each base station, the utilization rates corresponding to the conditions such as RE, REG, RBG, and the like can be used to measure the resource utilization rate of each base station.
In addition, a preset threshold value is set for the high-load cell to serve as a high-load judgment threshold value. Specifically, the preset threshold value RBRate _ Th of RB utilization and the preset threshold value CCERate _ Th of CCE utilization are set artificially. And if the RB utilization rate or the CCE utilization rate of a certain cell is continuously higher than a preset threshold value, setting the cell as a high-load cell. If the preset threshold value RBRate _ Th of the RB utilization rate is set to 80%, the corresponding cell is considered to be a high load cell as long as the RB utilization rate is continuously higher than 80%. Meanwhile, the duration of the judgment is also artificially set, and the RB utilization rate or the CCE utilization rate is ensured to be continuously kept in a stable state at or above a preset threshold value.
Specifically, when the RB utilization is continuously higher than an RB threshold in a preset threshold for a preset time, determining that a cell corresponding to a cell ID is a high load cell; and/or
And when the CCE utilization rate is continuously higher than a CCE threshold value in the preset threshold value within the preset time, determining that the cell corresponding to the cell ID is a high-load cell.
And when one of the judgment standards such as RB utilization rate and CCE utilization rate is continuously higher than the corresponding preset threshold value, determining the cell corresponding to the cell ID as a high-load cell.
And S13, identifying the public and private network convergence terminal currently in the high-load cell according to the UE capability information reported by each terminal.
In this step, after the terminal is powered on, the terminal automatically sends the respective corresponding UE capability information to the server, so that the server can identify the public and private network convergence terminal summarized by each terminal. The public-private network convergence terminal refers to a mobile terminal capable of automatically switching between a public network and a private network. After the terminal is started, when a user logs in, the UE capability information is reported to the server side. The UE capability information includes a UE capability identity and UE location information.
After the UE position information and the UE identification information reported by the terminal are obtained, the UE position information is matched with the cell ID of the determined high-load cell, and the terminal with the UE position information consistent with the cell ID of the high-load cell is selected. And after the terminal in the high-load cell is determined, selecting a public and private network convergence terminal according to the UE identification information reported by the terminal. Specifically, when each terminal reports its own UE identity information, different terminals may be given different UE identity information, for example, the private network terminal capability identifier is 00, the public network capability terminal is 01, and the public-private network convergence terminal is 10, at this time, the public-private network convergence terminal in which the UE identity information is 10 is selected.
And S14, triggering the identified public and private network convergence terminal to execute automatic network switching between the public network cell and the private network cell.
Here, the public and private network convergence terminals in the high-load cell are ranked first. In order to improve the spectrum efficiency of the cell as much as possible and also consider fairness, the signal quality of each public and private network convergence terminal is sequenced. Each public-private network convergence terminal uploads the UE capability information and also reports the UE Signal Quality of each public-private network convergence terminal, such as Reference Signal Received Power (RSRP), Signal to Interference Noise Ratio (SINR), Reference Signal Received Quality (RSRQ), and Received Signal Strength Indicator (RSSI).
And sequencing the public and private network convergence terminals according to the quality of the received signals. And finally, according to the sorted list of the public and private network convergence terminals screened by the principle, the server side issues a network switching command to the public and private network convergence terminal according to the list sequence, and the public and private network convergence terminal receives the command of the server and executes the automatic network switching operation.
And in addition, sequencing each public and private network convergence terminal according to the acquired user priority of the public and private network convergence terminal. The user priority mainly refers to a communication network to which the public-private network convergence terminal is mainly applied, for example, the user priority of the public-private network convergence terminal mainly applied to the private network is higher than that of the public-private network convergence terminal mainly applied to the public network. And sequencing the network switching sequence of the public and private network convergence terminals according to the user priority.
The public and private network convergence terminals can be firstly sorted according to the user priority, and then sorted for the second time according to the signal quality after the first sorting, and finally, the server side issues a network switching command to the public and private network convergence terminals according to the sorted list of the public and private network convergence terminals screened out according to the principle, and the public and private network convergence terminals receive the command of the server to execute the automatic network switching operation.
Based on the embodiment of the application, firstly, the cell ID and the base station resource utilization rate which are periodically sent by each base station of the public network cell and the private network cell are received, secondly, the high-load cell in which the base station resource utilization rate is higher than the preset threshold value in the public network cell and the private network cell is detected, finally, the public and private network convergence terminal which is currently located in the high-load cell is identified according to the UE capacity information reported by each terminal, and the identified public and private network convergence terminal is triggered to execute the automatic network switching between the public network cell and the private network cell. According to the embodiment of the application, the high-load cell with the base station utilization rate higher than the preset threshold value is determined through the periodically received cell ID and the base station resource utilization rate sent by the base station, then the public and private network convergence terminals in the high-load cell are selected, and automatic network switching is performed on the public and private network convergence terminals. The network load in each cell is judged in real time, a resident network is reasonably selected for the public and private network convergence terminal, the load of each cell is effectively reduced, and the service quality of the public and private network convergence terminal is improved.
In addition, when the public and private network convergence terminal is executed with the network switching operation according to the method, if the public and private network convergence terminal is suitable for the condition that the adjacent public network cell and private network cell both meet the high-load cell, the base station resource utilization rate of the two cells is compared, and the cell with the lower base station resource utilization rate is selected as the cell where the public and private network convergence terminal is to reside.

s25, sorting according to the signal quality and/or user priority of each public and private network convergence terminal;
and S26, issuing a network switching command to the public and private network convergence terminal according to the sequence of the list, and executing the automatic network switching operation after the public and private network convergence terminal receives the command of the server.

The problem that the judgment condition of the terminal for switching in the public and private networks is single and the network load is not considered comprehensively is effectively solved. Meanwhile, the situation that the terminal resides in a private network when the terminal is in the coverage range of the private network and a public network is avoided, the QoS of the user is obviously reduced when the private network is in a high load state, if the terminal is in a service state, the load of the cell is further intensified, the result that the performance of the cell is further deteriorated is caused, and the service quality of the user is improved.
