Detailed Description
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The inter-network roaming co-establishment sharing is a new 5G network sharing mode adopted by multiple operators, and under the inter-network roaming co-establishment sharing mode, the multiple operators share the visited network base station and the frequency band in the inter-network roaming mode. For example, a plurality of operators such as mobile, telecommunication, and Unicom use 700M frequency as a shared frequency, mobile is a visiting party, and telecommunication and Unicom are used as a home party. The inter-network roaming co-construction sharing mode can carry out low-frequency coverage sharing in low-capacity areas such as rural areas. In the shared network shared by the roaming of the different networks, the home 5G cell, the home 4G cell, and the shared cell shared by the roaming of the different networks are deployed as shown in fig. 1.
Fig. 2 is a flowchart illustrating a terminal access control method according to an embodiment of the present disclosure, as shown in fig. 2:
In one embodiment, the terminal includes a home terminal and the like, and the terminal can be a 4G, 5G and the like mobile phone, a tablet computer and the like. The configured voice service includes a VoNR service, etc. And the base station receives the terminal capability information sent by the terminal and determines whether the terminal supports the preset voice service or not based on the terminal capability information. The base station may acquire the terminal capability information of the terminal using various existing methods. For example, the base station receives the UE capability information reported by the terminal, and the base station determines whether the terminal is a 5G terminal and whether the terminal supports the VoNR service based on the UE capability information. The target terminal comprises a 5G terminal and the like which do not support VoNR and other services.
The different network roaming sharing cell comprises a cell of a different network roaming sharing 5G base station of a visiting network, and the visiting network is a visiting party network, such as a 5G network. The home network base station includes a home network 4G base station, and the like, and the home network is a home network, for example, a 4G network.
In one embodiment, the target terminal being in the connected state is that the target terminal is in the connected state with the base station. When the target terminal enters an idle state, the base station controls the target terminal not to reselect the different network roaming shared cell, or when the target terminal is in a connection state and triggers redirection, the base station controls the target terminal not to redirect to the different network roaming shared cell.
Various methods can be adopted for controlling the target terminal not to reselect or redirect to the heterogeneous network roaming shared cell. For example, when a target terminal enters an idle state, a base station issues cell reselection frequency point specific priority information to the target terminal, wherein in the cell reselection frequency point specific priority information, a priority corresponding to a cell frequency point of a home network base station is the highest priority.
Various methods can be adopted for issuing the cell reselection frequency point specific priority information to the target terminal. For example, the base station sends a radio resource control RRC message to the target terminal, where the RRC message carries information of cell reselection frequency point specific priority, and the RRC message may include multiple RRC messages and the like.
The base station forbids measuring the frequency point of the different network roaming shared cell for the target terminal in the state that the target terminal triggers redirection, and forbids sending the frequency point of the different network roaming shared cell to the target terminal through a Radio Resource Control (RRC) message in the redirection process; the RRC message may include various RRC messages, and the like.
In one embodiment, for a 5G terminal which does not support the VoNR service and has accessed a home 4G cell in a 5G heterogeneous network roaming area, the terminal can be always kept in the home network, and the terminal is prevented from accessing the heterogeneous network roaming cell. In the process that the terminal enters an idle state, the home 4G base station issues a special frequency priority and does not carry the frequency point of the different-network roaming shared cell in the RRC message aiming at the terminal.
When the terminal is in a connected state, if redirection is triggered, aiming at the terminal, the home party 4G base station prohibits measuring the frequency point of the 5G different network roaming cell, and simultaneously prohibits sending the frequency point of the 5G different network roaming cell (different network roaming shared cell) to the terminal in an RRC (redirected carrier info) message in the direction process. By the terminal access control method, the terminal can be always kept in the home network in the 5G different network roaming sharing area, and the problem of keeping the voice service continuity of the terminal is solved.
In one embodiment, as shown in fig. 3, the home 4G base station issues cell reselection frequency point specific priority information to the terminal in an RRC message, so as to prevent the terminal from being redirected to a 5G heterogeneous roaming network (heterogeneous roaming shared cell). When the terminal is at the edge of the 4G home cell and in the redirection process, the base station forbids measuring the frequency point of the 5G different network roaming cell, and forbids sending the frequency point of the 5G visiting network to the terminal through the RRC message in the orientation process, so that the terminal can be prevented from being redirected to the 5G different network roaming network.
In one embodiment, the home 4G base station supports the function of configuring the cell reselection frequency point specific priority information based on the terminal capability. And the attribution party 4G base station configures independent cell reselection frequency point specific priority information aiming at the terminal which does not support the VoNR service, and the frequency point of the visit party 5G network is not carried in the cell reselection frequency point specific priority information. The home party 4G base station supports the configuration of a redirection strategy based on the terminal capability, and does not trigger the redirection to the visit party 5G network aiming at the terminal which does not support VoNR.
Fig. 4 is a flowchart illustrating a terminal access control method according to another embodiment of the disclosure, as shown in fig. 4:
In step 404, the 5G terminal not supporting the VoNR does not reselect the 5G inter-network roaming cell (inter-network roaming shared cell).
In one embodiment, as shown in fig. 5, the present disclosure provides a base station 50 including a target terminal setting module 51, a terminal access control module 52, and a voice support determination module 53. The target terminal setting module 51 sets the terminal as the target terminal if it is determined that the terminal does not support the set voice service; the base station includes a home network base station and the like. The terminal access control module 52 controls the target terminal not to access the different-network roaming shared cell when the target terminal enters an idle state or when the target terminal is in a connected state. The voice support determination module 53 receives the terminal capability information sent by the terminal, and determines whether the terminal supports a preset voice service based on the terminal capability information.
In one embodiment, as shown in fig. 6, the terminal access control module 52 includes a first control unit 521 and a second control unit 522. When the target terminal enters an idle state, the first control unit 521 configures and issues cell reselection frequency point proprietary priority information to the target terminal so that the target terminal does not reselect to a heterogeneous network roaming shared cell; the special priority information of the cell reselection frequency point does not carry the frequency point information of the different network roaming shared cell. The first control unit 521 transmits a radio resource control RRC message to the target terminal, where the RRC message carries information of cell reselection frequency point specific priority.
The second control unit 522 controls the target terminal not to be redirected to the heterogeneous network roaming shared cell if it is determined that the target terminal triggers redirection in the connected state. If the second control unit 522 determines that the target terminal triggers redirection, the measurement of the frequency point of the inter-network roaming shared cell is prohibited for the target terminal, and the transmission of the frequency point of the inter-network roaming shared cell to the target terminal through a radio resource control RRC message is prohibited during redirection.
Fig. 7 is a block diagram of another embodiment of a base station according to the present disclosure. As shown in fig. 7, the base station may include a memory 71, a processor 72, a communication interface 73, and a bus 74. The memory 71 is used for storing instructions, the processor 72 is coupled to the memory 71, and the processor 72 is configured to execute the terminal access control method based on the instructions stored in the memory 71.
The memory 71 may be a high-speed RAM memory, a non-volatile memory (non-volatile memory), or the like, and the memory 71 may be a memory array. The storage 71 may also be partitioned and the blocks may be combined into virtual volumes according to certain rules. The processor 72 may be a central processing unit CPU, or an application Specific Integrated circuit asic, or one or more Integrated circuits configured to implement the terminal access control method of the present disclosure.
In one embodiment, the present disclosure provides a computer-readable storage medium storing computer instructions that, when executed by a processor, implement a terminal access control method as in any one of the above embodiments.
The terminal access control method, the base station and the storage medium in the above embodiments enable the terminal accessing the cell of the base station of the home network to be maintained in the home network for the terminal not supporting the set voice service under the condition of co-establishing the shared network by the roaming of the heterogeneous network, thereby avoiding the terminal accessing the shared cell of the roaming of the heterogeneous network, solving the problem that the terminal cannot perform the voice service in the roaming area of the heterogeneous network, improving the quality of the voice service and improving the use experience of the user.
