Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
The present embodiment provides a method for controlling roaming of a heterogeneous network, which is applied to a mobile terminal, and with reference to fig. 1, the method includes:
s1, judging whether a mobile terminal supports a new air interface bearing voice function or not; if yes, executing step S2; if not, executing the step S3;
s3, allowing the mobile terminal to perform new air interface network roaming of the different network;
and S3, forbidding the mobile terminal to start the new air interface network roaming of the different network.
Specifically, the mobile terminal automatically acquires or identifies whether SA and VoNR are supported currently; if the mobile terminal supports the SA and supports the VoNR, allowing the roaming of the new air interface network of the heterogeneous network, and using the new air interface network of the heterogeneous network when needed (for example, when the SA network of the local network does not cover); if the mobile terminal supports SA but does not support or the user disables VoNR, the new air interface network roaming of the different network is forbidden to be started so as to avoid generating abnormity when the voice call is dialed.
Because the mobile terminal only resides in the network, the core network cannot know whether the terminal supports the VoNR, the network side forbids the terminal which does not support the VoNR to carry out new air interface network roaming of the heterogeneous network, and the implementation is more feasible through the terminal side.
In the scheme, whether the terminal side supports VoNR or not is identified, and the terminal which does not support VoNR is forbidden to start the new air interface network roaming of the different network, so that on one hand, the implementation is more convenient than that of the network side, on the other hand, the problem that a user cannot use an SA network during international roaming is avoided, and the rationality and convenience of the control method for the different network roaming are improved.
In an implementation, step S3 includes:
judging whether the network coverage of the different network independent networking exists or not;
and if so, setting the different network independent networking network to be in a forbidden state on the mobile terminal.
In the scheme, the different-network independent networking network is set to be in the forbidden state at the terminal side, so that the realization is more convenient and faster, and the efficiency of the control method for the different-network roaming can be improved.
In an implementable solution, the step of setting the heterogeneous network independent networking network to a disabled state on the mobile terminal includes:
and setting the new air interface network number of the different network as a field for representing the forbidden public land mobile network on the mobile terminal.
Specifically, the network number of the network roaming by the heterogeneous network NR is unique, for example:
the network number of the roaming telecommunication NR network of the intermediate mobile subscriber is as follows: 46050
Roaming telecommunication NR network number of broadcasting and TV users: 46051
The network number of the mobile NR network in the roaming of the telecommunication user is as follows: 46021
The network number of the NR network in the roaming of the Unicom user is as follows: 46022
The roaming connected NR network number of the medium mobile subscriber: 46031
Roaming Unicom NR network number of broadcasting and television users: 46032
The roaming radio and television NR network number of the telecommunication user is as follows: 46060
The network number of the Unicom user roaming radio and television NR network: 46061
When the mobile terminal supports the SA but not the VoNR, the network number of the currently covered heterogeneous network NR roaming network is set to the forbidden PLMN, thereby preventing such terminal from performing heterogeneous network NR roaming.
In the scheme, the network number of the NR roaming of the different network is set to be in the forbidden mode, so that the influence on the international roaming of the user can be avoided, the rationality of the control method of the NR roaming of the different network is improved, and the use experience of the user is further improved.
In an implementable scheme, if the mobile terminal does not support the new air interface to carry the voice, before step S3, the method further includes:
judging whether the network is covered by the independent networking network of the local network;
if yes, controlling the mobile terminal to reside in the independent networking network of the local network;
if not, executing the step of judging whether the different network independent networking network covers.
Specifically, if the mobile terminal does not support the VoNR, the mobile terminal is controlled to reside in the SA under the condition that the SA is covered by the SA; and under the condition that the SA coverage of the local network does not exist, judging whether the SA coverage of the different network exists or not.
In the scheme, the mobile terminal can be ensured to normally use the SA of the local network for communication by controlling the mobile terminal to reside in the SA of the local network.
In an implementation scenario, step S3 is followed by: controlling the mobile terminal to reside through other network systems of the home network;
and/or the presence of a gas in the atmosphere,
and if no foreign network independent networking network coverage exists, controlling the mobile terminal to reside through other network systems of the network.
Specifically, after no inter-network independent networking network coverage exists or an inter-network independent networking network is disabled, the mobile terminal may attempt to complete camping in other systems of the home network, such as LTE (long term evolution of third generation mobile communication technology), UMTS (third generation mobile communication technology), or GSM (second generation mobile communication technology).
In the scheme, the situation that the network is completely disconnected can be avoided by trying to finish the residence in other modes of the local network, and the mobile terminal is ensured to maintain a normal communication function.
Referring to fig. 2, the following describes, in a specific implementation manner, an implementation process of the control method for the inter-network roaming provided in this embodiment:
(1) The terminal sets 5G predicted (5G is preferentially used) and supports SA;
(2) The terminal judges whether the VoNR is supported or the user disables the VoNR function; if yes, normal different network NR roaming is carried out according to the requirement; if not, judging whether the local network SA is covered;
(3) If the coverage of the SA exists in the local network, residing in the SA cell of the local network;
(4) If no local network SA coverage exists and different network SA coverage exists, the terminal judges that the network number of the roaming NR network is a forbidden PLMN, and the network number of the roaming NR network is set as a forbidden PLMN, so that the different network NR roaming is avoided;
(5) If the local network is not covered by the SA and the foreign network is not covered by the SA, trying other systems (LTE/UMTS/GSM) of the local network to finish residing; if the network number of the roaming NR network is set as a forbidden PLMN, trying to complete residence in other modes (LTE/UMTS/GSM) of the local network if the local network is not covered by the SA and the heterogeneous network is covered by the SA.
In this embodiment, whether SA and VoNR are supported or not is identified from the terminal side, and when SA is supported but VoNR is not supported, the reliability and efficiency of the control method for the heterogeneous network roaming can be improved by prohibiting the heterogeneous network roaming in a manner such as setting the network number of the roaming NR network to forbidden PLMN, and trying to camp in another system of the home network, thereby improving the roaming use experience of the user.

In the scheme, whether the terminal side supports VoNR or not is identified, and the terminal which does not support VoNR is forbidden to start the new air interface network roaming of the different network, so that on one hand, the implementation is more convenient than that of the network side, on the other hand, the problem that a user cannot use an SA network during international roaming is avoided, and the rationality and convenience of the control system for the different network roaming are improved.
