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 following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
The different network roaming co-establishment sharing is a new 5G network sharing mode adopted by a plurality of operators, and the plurality of operators share the base station and the frequency band of the visiting network in a different network roaming mode under the different network roaming co-establishment sharing mode. Multiple operators such as mobile, telecom, unicom etc. use 700 Mfrequency as shared frequency, mobile as visitor, telecom, unicom etc. as home etc. The different network roaming co-establishment sharing mode can carry out low-frequency coverage sharing in rural areas and other low-capacity areas. In the heterogeneous roaming co-established shared network, the deployment of the home 5G cell, the home 4G cell and the heterogeneous roaming 5G shared cell is shown in fig. 1.
Fig. 2 is a flow chart illustrating an embodiment of a terminal access control method according to the present disclosure, as shown in fig. 2:
In 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 comprises a home network base station and the like.
In one embodiment, the terminal includes a home terminal, and the terminal may be a mobile phone such as 4G or 5G, a tablet computer, and the like. The voice services set include VoNR services, etc. The base station receives terminal capability information sent by the terminal and determines whether the terminal supports preset voice service or not based on the terminal capability information. The base station may acquire terminal capability information of the terminal using various existing methods. For example, the base station receives UE capability information reported by the terminal, and the base station determines whether the terminal is a 5G terminal, whether the terminal supports VoNR services, and the like based on the UE capability information. The target terminal includes a 5G terminal or the like that does not support VoNR or the like.
The heterogeneous network roaming sharing cell comprises a cell of a 5G base station and the like of a visiting network, wherein the visiting network is a visiting network, such as a 5G network and the like. 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 and the like.
Step 202, when the target terminal enters an idle state or is in a connection state, the base station controls the target terminal not to access the heterogeneous roaming shared cell.
In one embodiment, the target terminal is in a connection state, that is, the target terminal is in a connection 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 connection state and the redirection is triggered, the base station controls the target terminal not to redirect to the heterogeneous roaming shared cell.
Various methods can be employed to control the target terminal not to reselect or redirect to a different network roaming shared cell. For example, when the target terminal enters an idle state, the base station issues cell reselection frequency point proprietary priority information to the target terminal, wherein in the cell reselection frequency point proprietary priority information, the priority corresponding to the cell frequency point of the home network base station is the highest priority.
The method for transmitting the cell reselection frequency point proprietary priority information to the target terminal can be various. For example, the base station sends a radio resource control RRC message to the target terminal, where the RRC message carries cell reselection frequency point specific priority information, and the RRC message may include multiple RRC messages and so on.
And the base station prohibits the measurement of the frequency point of the different network roaming shared cell for the target terminal in the state that the target terminal triggers the redirection, and prohibits the transmission of the frequency point of the different network roaming shared cell to the target terminal through the Radio Resource Control (RRC) message in the redirection process, wherein the RRC message can comprise various RRC messages and the like.
In one embodiment, for 5G terminals that have accessed home 4G cells in a 5G foreign roaming region that do not support VoNR services, such terminals can be kept at the home network at all times, preventing such terminals from re-accessing the foreign roaming cells. In the process that the terminal enters an idle state, the home 4G base station transmits a special frequency priority to the terminal in an RRC message, wherein the special frequency priority does not carry the frequency point of the roaming sharing cell of the different network.
When the terminal is in a connection state, if redirection is triggered, aiming at the terminal, the home 4G base station prohibits measuring the frequency point of the 5G heterogeneous roaming cell, and prohibits issuing the frequency point of the 5G heterogeneous roaming cell (heterogeneous roaming shared cell) to the terminal in an RRC (REDIRECTED CARRIER info) message in the orientation process. By the terminal access control method, the terminal can be always kept in the home network in the 5G heterogeneous network roaming sharing area, and the problem of keeping the voice service of the terminal continuous is solved.
In one embodiment, as shown in fig. 3, the home 4G base station issues cell reselection frequency specific priority information to the terminal in an RRC message, which can prevent the terminal from redirecting to the 5G foreign roaming network (foreign roaming shared cell). When the terminal is at the edge of the 4G home cell and in the redirection process, the base station prohibits the measurement of the 5G heterogeneous roaming cell frequency point, and simultaneously prohibits the transmission of the 5G visiting network frequency point to the terminal through the RRC message in the orientation process, thereby preventing the terminal from being redirected to the 5G heterogeneous roaming network.
In one embodiment, the home 4G base station supports the functionality of configuring cell reselection frequency specific priority information based on terminal capabilities. The home 4G base station configures special priority information of individual cell reselection frequency points aiming at a terminal which does not support VoNR service, and the special priority information of the cell reselection frequency points does not carry the frequency points of the visitor 5G network. The home 4G base station supports configuring redirection policies based on terminal capabilities, and does not trigger redirection to the visitor 5G network for terminals that do not support VoNR.
Fig. 4 is a flow chart illustrating another embodiment of a terminal access control method according to the present disclosure, as shown in fig. 4:
In step 401, the home network 4G base station identifies the terminal capability, determines whether the terminal is a 5G terminal and does not support VoNR traffic, and if yes, proceeds to step 402.
In step 402, the home network 4G base station marks the terminal to characterize that the terminal does not support VoNR services.
Step 403, if the terminal enters idle state, the home network 4G base station issues the special priority information of the cell reselection frequency point in the RRC message for the terminal, and does not carry the frequency point information of the heterogeneous roaming shared cell.
In step 404, the 5G terminal that does not support VoNR does not reselect to the 5G foreign roaming cell (foreign roaming shared cell).
Step 405, if redirection is triggered, the home network 4G base station prohibits measurement of the frequency point of the 5G foreign network roaming cell (foreign network roaming shared cell), and prohibits sending the frequency point of the 5G foreign network roaming cell to the terminal through the sent RRC (REDIRECTED CARRIER info) message in the redirection process.
In step 406, the 5G terminal that does not support VoNR is not redirected to the 5G foreign roaming 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 a target terminal if it is determined that the terminal does not support the set voice service, wherein 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 heterogeneous roaming shared cell when the target terminal enters an idle state or when the target terminal is in a connected state. The voice support determining module 53 receives terminal capability information transmitted from 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 for the target terminal so that the target terminal does not reselect to a different network roaming shared cell, wherein the cell reselection frequency point proprietary priority information does not carry frequency point information of the different network roaming shared cell. The first control unit 521 sends a radio resource control RRC message to the target terminal, where the RRC message carries cell reselection frequency point proprietary priority information.
The second control unit 522 controls the target terminal not to be redirected to the foreign roaming shared cell if it is determined that the target terminal triggers redirection while the target terminal is in the connected state. The second control unit 522 prohibits measurement of the frequency point of the heterogeneous roaming shared cell for the target terminal if it is determined that the target terminal triggers redirection, and prohibits transmission of the frequency point of the heterogeneous roaming shared cell to the target terminal through the radio resource control RRC message during redirection.
