[0029] The present disclosure is described more fully below with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are described. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0030] Inter-network roaming co-construction and sharing is a new 5G network sharing mode adopted by multiple operators. In this mode, multiple operators use inter-network roaming to share visited network base stations and frequency bands. For example, multiple operators such as China Mobile, China Telecom, and China Unicom use the 700M frequency as the shared frequency, with China Mobile as the visited party, and China Telecom and China Unicom as the owned party. Inter-network roaming co-construction and sharing can share low-frequency coverage in low-capacity areas such as rural areas. In the inter-network roaming co-construction and sharing network, the deployment of the owned party 5G cell, the owned party 4G cell, and the inter-network roaming 5G shared cell is as follows: Figure 1 shown.

[0031] Figure 2 FIG. 1 is a flow chart of an embodiment of a terminal access control method according to the present disclosure, as shown in FIG. Figure 2 As shown:

[0032] Step 201: If the base station determines that the terminal does not support the set voice service, the base station sets the terminal as a target terminal; wherein the base station includes a home network base station, etc.

[0033] In one embodiment, the terminal includes a home terminal, etc., and the terminal may be a 4G, 5G or other mobile phone, a tablet computer, etc. The set voice service includes a VoNR service, etc. The base station receives the terminal capability information sent by the terminal, and determines whether the terminal supports the preset voice service based on the terminal capability information. The base station can use multiple existing methods to obtain the terminal capability information of the terminal. For example, the base station receives the UE capability capability information reported by the terminal, and the base station determines whether the terminal is a 5G terminal based on the UE capability capability information, and whether the terminal supports the VoNR service, etc. The target terminal includes a 5G terminal that does not support services such as VoNR, etc.

[0034] The inter-network roaming shared cell includes the cell of the inter-network roaming shared 5G base station of the visited network, and the visited network is the visited network, such as the 5G network, etc. The home network base station includes the home network 4G base station, and the home network is the home network, such as the 4G network, etc.

[0035] Step 202: When the target terminal enters an idle state or is in a connected state, the base station controls the target terminal not to access a different network roaming shared cell.

[0036] In one embodiment, the target terminal is in a connected state, that is, the target terminal is in a connected state with the base station. When the target terminal enters an idle state, the base station controls the target terminal not to reselect to the heterogeneous roaming shared cell, or, when the target terminal is in a connected state and redirection is triggered, the base station controls the target terminal not to redirect to the heterogeneous roaming shared cell.

[0037] There are many methods for controlling the target terminal not to reselect or redirect to the roaming shared cell of the different network. For example, when the target terminal enters the idle state, the base station sends the cell reselection frequency point dedicated priority information to the target terminal, wherein in the cell reselection frequency point dedicated priority information, the priority corresponding to the cell frequency point of the home network base station is the highest priority.

[0038] There are many methods for sending 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, the RRC message carries the cell reselection frequency point specific priority information, and the RRC message may include multiple RRC messages.

[0039] When the target terminal triggers redirection, the base station prohibits the target terminal from measuring the frequency of the inter-network roaming shared cell, and prohibits sending the frequency of the inter-network roaming shared cell to the target terminal through the radio resource control RRC message during the redirection process; the RRC message may include multiple RRC messages, etc.

[0040] In one embodiment, for 5G terminals that do not support VoNR services and have accessed the home 4G cell in the 5G inter-network roaming area, they can always remain in the home network to prevent such terminals from accessing the inter-network roaming cell again. When the terminal enters the idle state, the home 4G base station sends a dedicated frequency priority in the RRC message for such terminals and does not carry the frequency of the inter-network roaming shared cell.

[0041] When the terminal is in a connected state, if redirection is triggered, for such terminals, the home party 4G base station is prohibited from measuring the frequency of the 5G inter-network roaming cell, and is prohibited from sending the frequency of the 5G inter-network roaming cell (inter-network roaming shared cell) to such terminals in the RRC (Redirected carrier info) message during the orientation process. Through the terminal access control method disclosed in the present invention, such terminals can always be kept in the home party network in the 5G inter-network roaming shared area, solving the problem of maintaining the continuity of voice services for such terminals.

[0042] In one embodiment, Figure 3 As shown, the home 4G base station sends the cell reselection frequency point exclusive priority information to the terminal in the RRC message, which can prevent the terminal from being redirected to the 5G inter-network roaming network (inter-network roaming shared cell). When the terminal is at the edge of the 4G home cell and in the redirection process, the base station is prohibited from measuring the 5G inter-network roaming cell frequency point, and is prohibited from sending the 5G visited network frequency point to the terminal through the RRC message during the orientation process, which can prevent the terminal from being redirected to the 5G inter-network roaming network.

[0043] In one embodiment, the home 4G base station supports the function of configuring the cell reselection frequency point dedicated priority information based on the terminal capability. The home 4G base station configures separate cell reselection frequency point dedicated priority information for terminals that do not support VoNR services, and does not carry the frequency of the visited 5G network in the cell reselection frequency point dedicated priority information. The home 4G base station supports the configuration of the redirection strategy based on the terminal capability, and does not trigger the redirection to the visited 5G network for terminals that do not support VoNR.

[0044] Figure 4 FIG. 1 is a flow chart of another embodiment of the terminal access control method according to the present disclosure, as shown in FIG. Figure 4 As shown:

[0045] In step 401, the 4G base station in the home network identifies the terminal capabilities and determines whether the terminal is a 5G terminal and whether it does not support VoNR services. If both are yes, proceed to step 402.

[0046] Step 402: The home network 4G base station marks the terminal to indicate that the terminal does not support the VoNR service.

[0047] Step 403, if the terminal enters the idle state, the home network 4G base station sends the cell reselection frequency-specific priority information in the RRC message for such terminal, without carrying the frequency information of the shared cell of the roaming network.

[0048] Step 404: 5G terminals that do not support VoNR will not reselect to the 5G inter-network roaming cell (inter-network roaming shared cell).

[0049] Step 405: If redirection is triggered, the home network 4G base station is prohibited from measuring the frequency of the 5G inter-network roaming cell (inter-network roaming shared cell), and is prohibited from sending the frequency of the 5G inter-network roaming cell to this terminal through the RRC (Redirected carrier info) message sent during the redirection process.

[0050] Step 406: 5G terminals that do not support VoNR will not be redirected to 5G inter-network roaming cells.

[0051] In one embodiment, Figure 5 As shown, 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. If the target terminal setting module 51 determines that the terminal does not support the set voice service, it sets the terminal as a target terminal; wherein the base station includes a home network base station, etc. The terminal access control module 52 controls the target terminal not to access the cross-network roaming shared cell when the target terminal enters an idle state or 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 the preset voice service based on the terminal capability information.

[0052] In one embodiment, Figure 6 As shown, the terminal access control module 52 includes a first control unit 521 and a second control unit 522. When the target terminal enters the idle state, the first control unit 521 configures the cell reselection frequency point specific priority information for the target terminal and sends it down, so that the target terminal does not reselect to the inter-network roaming shared cell; wherein the cell reselection frequency point specific priority information does not carry the frequency point information of the inter-network roaming shared cell. The first control unit 521 base station sends a radio resource control RRC message to the target terminal, wherein the RRC message carries the cell reselection frequency point specific priority information.

[0053] The second control unit 522 controls the target terminal not to redirect to the heterogeneous roaming shared cell if it is determined that the target terminal has triggered redirection when the target terminal is in a connected state. If the second control unit 522 determines that the target terminal has triggered redirection, it prohibits the target terminal from measuring the heterogeneous roaming shared cell frequency point, and prohibits sending the heterogeneous roaming shared cell frequency point to the target terminal through the radio resource control RRC message during the redirection process.
