Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
Currently, high definition calls, such as VoLTE/VoNR calls, of a communication network may be handed over to 1x srLTE. For example, in case of failure or no network acknowledgement received when an IMS VoLTE/VoNR call is initiated over the current communication network, a handover to the 1x network is performed for registration and re-initiation of the call. Such registration by switching to the 1x network may fail due to the terminal retransmitting the IMS call busy.
For example, an IMS VoLTE/VoNR call from a terminal fails in the following scenario:
(1) The terminal registers in 5G, while the IMS registers normally.
(2) The terminal initiates an IMS call, and encounters a radio access request failure (rach fail) in the calling process.
(3) After the radio access request fails, the terminal attempts a tracking area update (tau, tracking area update) to resume synchronization with the network.
(4) However, in some 5G network environments tau may take longer, for example, more than 5 seconds (normally 1-2s complete).
(5) In this case, a trigger timeout of the previously initiated IMS call is often encountered, and an IMS call failure triggers a handover to the 1xc2k network. While NAS receives the tau accept message.
(6) The NAS reestablishes the data resource bearer after receiving the tau accept message. The terminal resends the wireless access request initiated by the previous IMS call.
(7) The terminal registers on the 1x c2k network and simultaneously re-initiates the call.
(8) But since the radio access request initiated by the IMS call retransmitted in the previous step (6) is already sent to the network, and the network sends the request to the called receiving end synchronously, the call initiated by the terminal in step (7) will fail due to the busy counterpart, resulting in the failure of the call.
The present disclosure proposes a communication method to solve the problem of such IMS VoLTE/VoNR call failure. The communication method comprises the following steps: when the terminal sends a call request based on VoLTE to a network side, a network switching timer is started, and the network switching timer is used for timing switching of communication based on VoLTE into communication based on a 2G/3G network; determining whether a set condition is met when the network switching timer expires; when the set condition is met, switching the VoLTE-based call request into a call request based on a second generation/third generation 2G/3G network, and sending the call request based on the 2G/3G network to a network side; or prohibiting switching the VoLTE-based call request to the 2G/3G network-based call request in a set time period, and continuing to send the VoLTE-based call request to a network side.
When the IMS VoLTE/VoNR call is initiated through the current communication network, the method adopts an alternative mode to force the terminal to be switched to initiate the call based on the 2G/3G network, or to continue to initiate the IMS VoLTE/VoNR call without being switched to the 2G/3G network, so that the conflict problem caused by initiating the call based on the 2G/3G network and the IMS VoLTE/VoNR call is avoided, the call failure is avoided, and the use experience of a user is improved.
The terminal in the present disclosure is a terminal capable of communicating through a communication network after inserting a SIM card, such as a mobile phone, PAD, wearable device, or the like.
Fig. 1 is a flowchart illustrating a communication method applied to a terminal according to an exemplary embodiment, the method including the steps of:
step 101, when the terminal sends a high-definition call request to a network side, starting a network switching timer, where the network switching timer is used to time a network fallback operation for the high-definition call request, where the network fallback operation is a call request for switching the high-definition call request to a first-generation network based on a network to which the high-definition call request belongs;
step 102, determining that the network switching timer expires;
step 103, when meeting call guarantee conditions, performing the network fallback operation on the high-definition call request, and sending a call request based on the prior network to a network side; or prohibiting the network fallback operation of the high-definition call request in a set time period, and continuously sending the high-definition call request to a network side.
In step 101, when the terminal sends a high-definition call request (when a call based on VoLTE/VoNR is initiated), a network switching timer is started. That is, when the terminal initiates the high definition call, the network switching timer starts to count. The expiration time of the network switch timer can be set according to actual needs, and can be set to 6s generally. The network switch timer may be used to facilitate switching the communication of the high definition call request to communication based on the prior art network.
In step 102 and step 103, it is determined that the timing of the network switching timer reaches the expiration time, if the guaranteed call condition is met, the high-definition call request is switched to the call request based on the first-generation network, or the high-definition call request is continuously sent to the network side, and the call is forbidden to be switched to the first-generation network within a set time period, so as to avoid the conflict caused by simultaneous call based on the first-generation network and the high-definition call request. The set time period here takes into account the time required for the terminal to complete the location area update procedure. Because, after the terminal completes the location area update procedure, the high-definition call request is sent again.
When the high-definition call is initiated through the current communication network, such as the failure of IMS VoLTE/VoNR call, the method adopts an alternative mode to force the terminal to be switched to initiate the call based on the first-generation network, or to continue to initiate the high-definition call without being switched to the first-generation network, so that the conflict problem caused by initiating the call based on the first-generation network and the high-definition call is avoided, the failure of the call is avoided, and the use experience of a user is improved.
In an alternative embodiment, the call guarantee condition is:
the data resource bearing between the terminal and the network side is in an inactive state, and the position area updating process of the terminal is not completed.
In this embodiment, the call security condition determined when the call security operation is performed is that the data resource bearer between the terminal and the network side is in an inactive state, and the location area update procedure of the terminal is not completed.
In an optional implementation manner, the performing the network fallback operation on the high-definition call request includes:
and deleting the high-definition call request to be retransmitted.
In this embodiment, when the high-definition call request is, for example, a VoLTE-based call request, deletion of the VoLTE-based call request to be retransmitted may be achieved by deleting the INVITE message request remaining in a Packet Data Convergence (PDCP) queue. The INVITE message request here is a message request defined by a session initiation protocol (SIP, a main protocol on which an operator high definition voice call is based), and an originating call is issued through the INVITE message request. Thus, deletion of the INVITE message request corresponds to deletion of the VoLTE-based call request. Even if the terminal subsequently completes the location area updating process, the VoLTE-based call request can not be sent out any more, so that call collision is avoided.
In an optional implementation manner, prohibiting the network fallback operation of the high-definition call request in a set period of time, and continuously sending the high-definition call request to a network side, including:
resetting the network switching timer, and prohibiting the high-definition call request from carrying out the network fallback operation before the network switching timer expires;
and continuing to send the high-definition call request to a network side.
In this embodiment, switching the call to the previous generation network is prohibited and the high definition call request continues to be sent. Upon expiration of the network switch timer, the network switch timer is reset, i.e., the network switch timer is caused to restart counting. The handover of the call to the previous generation network is prohibited, i.e. the handover of the call to the previous generation network is not initiated, until the expiration of the time when the network handover timer is restarted. Thus, only high-definition call is ensured to be executed, and call collision is avoided.
In an alternative embodiment, the method further comprises:
judging whether the call guarantee condition is met;
before the judging whether the call guarantee condition is met, the method further comprises:
and determining that the wireless access request related to the high-definition call request fails, and executing the position area update.
The method is executed after the position area is updated after the high-definition call request is sent to fail. As described above, in the prior art, the operation of switching the call to the previous generation network is started, usually when the network switch timer expires, and such a call through the previous generation network may fail due to the terminal retransmitting the high definition call busy. Therefore, in the method, when the network switching timer expires, instead of starting to switch the call to the first generation network, it is determined whether the call guarantee condition is satisfied.
In an optional implementation manner, the continuing to send the high-definition call request to the network side includes:
and after the position area updating process of the terminal is completed, sending the high-definition call request to a network side.
The call guarantee condition is that the data resource bearing between the terminal and the network side is in an inactive state, and the position area updating process is not completed. And after the network switching timer expires, the network switching timer is reset to prohibit the call from being switched to the first generation network, and when the network switching timer after being reset does not expire, the terminal completes the location area updating process, and at the moment, a high-definition call request is sent to the network side.
As described above, the expiration time of the network handover timer is set to 6s, and in some network environments, the location area update may take longer to exceed 6s (normally 1-2 s), for example 7s. Thus, after the network switching timer is reset, the location area updating process is completed before the reset network switching timer expires again, so that the high-definition call request is sent to the network side. So that it does not trigger a handover of the call to the previous generation network.
In an alternative embodiment, the method further comprises:
after the call request based on the first generation network is sent to the network side, communication is carried out based on the first generation network; or alternatively
And after the high-definition call request is continuously sent to a network side, carrying out communication based on the network to which the high-definition call request belongs.
In this embodiment, after the call request based on the first-generation network is sent to the network side, subsequent communication is performed based on the first-generation network. Similarly, after the high-definition call request is sent to the network side, subsequent communication is performed based on the network to which the high-definition call request belongs.
In an alternative embodiment, the high-definition call request is a VoLTE-based call request or a VoNR-based call request.
The following specific embodiments are described in the context of VoLTE-based call requests and 2G/3G networks.
Specific embodiments according to the present disclosure are described below in connection with specific application scenarios. The terminal in this embodiment is a mobile phone, as shown in fig. 2, the method includes the following steps:
in step 201, the terminal performs VoLTE registration procedure and initiates VoLTE call, and at the same time starts a network switching timer, and the expiration time of the network switching timer is set to 6s.
Step 202, after the radio access request is initiated, a radio access request failure message is received.
Step 203, triggering RRC (radio resource control) connection reestablishment, initiating a reestablishment request, the reestablishment request being rejected by the network.
In step 204, it is detected that the frequency number of the terminal is switched from 1825 to 100 and the Tracking Area Identity (TAI) is changed, thus triggering a location area update.
Step 205, determining that the network switch timer expires, determining whether the data resource bearer between the terminal and the network side is inactive, and not completing the location area update procedure of the terminal.
Step 206, when the above condition is satisfied, resetting the network switch timer, i.e. restarting the timing of 6s.
Step 207, after resetting the network switch timer 1s, the mobile phone completes the location area update process, and resends the voice over lte call request to the network side.
Step 208, the subsequent VoLTE network-based communication continues.
It should be noted that, after step 205, a procedure of deleting the VoLTE-based call request to be retransmitted and switching the VoLTE-based call request to a 2G/3G network-based call request may also be performed.
The present disclosure also provides a communication apparatus, which is applied to a terminal, as shown in fig. 3, and includes:
