Description
Technical Field
The present disclosure relates to mobile terminal technologies, and in particular, to a method, an apparatus, and a storage medium for switching voice services.
Background
With the large-scale commercial use of Voice over LTE (VoLTE for short), some LTE weak coverage scenarios, such as residential areas, indoor and other weak coverage scenarios, face the problem of poor Voice service quality. In order to solve the problem of Voice service quality under the LTE weak coverage scenarios, a technical scheme is proposed in which a Voice over WIFI (shortly: voip) technology on WIFI is fused with a voip technology so as to provide Voice service for a user.
In particular, the VoWIFI technology and the VoLTE technology may share an IPM Multimedia Subsystem (IMS) network. And if the mobile terminal is currently accessed into the LTE network to perform IMS voice service, VoLTE voice service is performed, and if the mobile terminal is currently accessed into the WIFI network to perform IMS voice service, VoWIFI voice service is performed. In the voice service process, the mobile terminal can monitor the currently accessed network, and if the signal quality of the currently accessed network of the mobile terminal is poor, the mobile terminal is directly switched to another network to continue the IMS voice service. For example, if the mobile terminal currently performs the VoLTE voice service, and if the mobile terminal monitors that the network signal quality of the currently accessed LTE network is poor, the mobile terminal is switched to the WIFI network to perform the volga voice service, thereby implementing the connection of the IMS voice service. The handover process from the voice over wifi service to the voice over lte service is similar. Therefore, bidirectional seamless switching between VoWIFI and VoLTE can be realized at present.
However, after the existing bidirectional seamless handover technology between the WIFI network and the VoLTE network is handed over to the LTE network from the WIFI network, or after the LTE network is handed over to the WIFI network from the LTE network, the situation that the voice service quality is worse often occurred, and the voice service quality requirement of the user cannot be met.

In the voice service switching method, apparatus, and storage medium provided in this embodiment of the present application, when it is determined that the service quality of the IMS voice service in the first network does not meet the voice quality requirement, the IMS voice service is not directly switched to the second network, but it is further determined whether the signal strength of the second network can meet the voice quality requirement of the IMS voice service. And under the condition that the signal intensity of the second network can meet the voice quality requirement of the IMS voice service, switching the IMS voice service to the second network.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first," "second," and the like in the description and in the claims, and in the drawings, of the embodiments of the application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1a is a schematic diagram of a communication system applied in the embodiment of the present application. As shown in fig. 1a, the communication system includes a network device 11, a network device 12 and a mobile terminal 13. It is understood that in an actual communication system, there may be one or more of the network device 11, the network device 12 and the mobile terminal 13, and fig. 1a is only one example.
In fig. 1a, the network device 11 may be an access device in a cellular network, for example, an access device in an LTE network and an evolved network thereof, such as an evolved Node B (eNB or eNodeB), or a relay station, and the like, and a coverage area thereof is illustrated as a solid circled area. The network device 12 may be an Access Point (AP) device in the WLAN, and its coverage area is illustrated as an area enclosed by a dashed line. It is understood that, in general terms, the coverage area of the cellular network access device is larger than that of the WLAN access device, that is, the area of the real coil shown in fig. 1a is larger than that of the imaginary coil, but the coverage area of the WLAN access device may be larger than or equal to that of the cellular network access device in the case that the transmission power of the cellular network access device is smaller. Furthermore, fig. 1a only shows that the coverage of the cellular network includes the coverage of the WLAN, and it is understood that the coverage of the cellular network and the coverage of the WLAN may partially overlap or not overlap.
The mobile terminal 13 may also be referred to as a terminal device, a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a User terminal, a wireless communication device, a User agent, or a User Equipment. The mobile terminal may be a smartphone, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication capability or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, etc. In the embodiment of the present application, the mobile terminal 13 has an interface for communicating with both a cellular network and a WLAN.
Fig. 1b is a schematic diagram of an IMS voice service network architecture applied in the embodiment of the present application. As shown in fig. 1b, the network architecture comprises: an eNB 21 in an LTE network, an AP 22 in a WIFI network, a mobile terminal 13, and an IMS service platform 23 with an IMS voice server 231 deployed.
The mobile terminal 13 may communicate with the AP 22 in the WIFI network through the WIFI interface, and the mobile terminal 13 may also communicate with the eNB 21 in the LTE network through the LTE network interface. The eNB 21 may be connected to the IMS voice server 231 through a network Entity (not shown) such as a Mobility Management Entity (MME), a serving gateway, and the like. The AP 22 may be connected to the IMS voice server 231 through a network entity (not shown) such as an evolved packet data Gateway (ePDG) in the LTE network. Therefore, the network architecture shown in fig. 1b can support the voice over wifi service and the voice over lte service of the mobile terminal 13.
In connection with fig. 1a and 1b, seamless handover between VoWIFI and VoLTE may involve the following scenarios, for example:
in a first scenario, the mobile terminal 13 leaves from a coverage area of a WIFI network and enters into a coverage area of an LTE network in a process of performing a voice over WIFI service;
in a second scenario, the mobile terminal 13 leaves from the coverage of the LTE network and enters into the coverage of the WIFI network in the process of performing the VoLTE voice service;
in a third scenario, the mobile terminal 13 is simultaneously located in the coverage of the WIFI network and the coverage of the LTE network (as shown in fig. 1 a) during the VoWIFI voice service, and the quality of the IMS voice service in the WIFI network is degraded.
In a fourth scenario, the mobile terminal 13 is simultaneously located in the coverage of the WIFI network and the coverage of the LTE network (as shown in fig. 1 a) during the VoLTE voice service, and the quality of the IMS voice service in the LTE network is degraded.
Aiming at seamless switching between VoWIFI and VoLTE under the scenes, the technical scheme provided by the embodiment of the application can at least ensure that the voice service quality of the IMS voice service in the switched network does not become poor, thereby ensuring the continuity of the IMS voice service to a certain extent and meeting the voice service quality requirement of a user.
The following explains a voice service switching method provided in the embodiment of the present application by a specific embodiment with reference to fig. 1a and 1 b.
Fig. 2 is a flowchart of a voice service switching method according to an embodiment of the present application. The embodiment of the application provides a voice service switching method, which can be executed by a voice service switching device, and the device can be realized in a software and/or hardware mode. Illustratively, the voice service switching device may be a mobile terminal as mentioned above, such as the mobile terminal 13 shown in fig. 1, or the voice service switching device may be a chip or a circuit, etc., which may be integrated with the mobile terminal as mentioned above. Next, a mobile terminal will be described as an execution subject.
Referring to fig. 2, the voice service switching method includes the following steps:
s201, the mobile terminal determines whether the service quality of the IMS voice service on the first network meets the voice quality requirement.
Here, the first network is a network to which the mobile terminal is currently connected.
As mentioned above, the IMS voice service includes a VoLTE voice service and a VoWIFI voice service, and the mobile terminal may perform bidirectional seamless handover between the volta and VoLTE services. Therefore, when the mobile terminal device is in the IMS voice service process, for example, the following two cases are included:
in the first case, the mobile device accesses the LTE network to perform an IMS voice service, i.e., performs a VoLTE voice service. At this time, the first network is an LTE network.
In the second case, the mobile device accesses the WIFI network to perform IMS voice service, i.e., perform VoWIFI voice service. In this case, the first network is a WIFI network.
In the above case, the voice quality requirement described in the embodiment of the present application is not limited to that the network signal is good (for example, the signal strength of the first network is greater than the preset signal threshold value) to indicate that the voice quality requirement can be met. That is to say, the voice quality requirement may have multiple expression forms, and correspondingly, the service quality of the IMS voice service on the first network may also be expressed in multiple expression forms, for example, the network signal strength of the first network and the packet loss rate of the IMS voice service on the first network, the delay of the IMS voice service on the first network, the jitter of the IMS voice service on the first network, and the like.
The jitter of the IMS voice service in the first network, also referred to as the variation of the time delay of the IMS service in the first network, is a time difference between the arrival of all transmitted data packets in the IMS voice service process. In the IMS voice service, the effect of jitter expression is similar to the effect of packet loss, and some words are not audible or wrong. The amount of jitter depends on the degree of difference in packet path times, with greater degrees of difference providing greater jitter. For example, if the jitter value is greater than 5ms, the quality of the IMS voice service is considered to be very poor. To ensure the quality of service of IMS voice services, the end-to-end jitter in an IMS network cannot exceed 10 ms.
The delay of the IMS voice service on the first network refers to the time that the voice is waiting for the receiving end from the transmitting end. The delay can cause a blank in the voice conversation process, resulting in distortion of the voice and a terminal of the conversation. The time length of the delay begins to be perceived by a listener within 100-200 ms. If the delay reaches 200ms, then a severe session interruption starts. Through Ping test, the time delay from Shanghai IMS user network Edge device (Customer Edge, CE for short) to Beijing IMS CE is 35ms, and in order to ensure the service quality of IMS voice service, the end-to-end jitter in the IMS network cannot exceed 50 ms.
For the packet loss rate of the IMS voice service on the first network, it can be understood that the packet loss is a key factor affecting the service quality of the IMS voice service. The difference value of the number of the data packets between the sending end and the receiving end of the data packets is the number of the transmission lost packets. The voice data packet is transmitted by using Real-time Transport Protocol (RTP), and there is no retransmission mechanism, and any packet loss and disorder will affect the service quality of the IMS voice service. When a small number of packet losses are randomly distributed, the receiver cannot easily perceive poor voice quality. Through Ping test, the packet loss rate from Shanghai IMS CE to Beijing IMSCE is 0, and in order to ensure the service quality of IMS voice service, the end-to-end packet loss rate in IMS network cannot exceed 1%.
S202, if the service quality of the IMS voice service on the first network does not meet the voice quality requirement, the mobile terminal determines whether the network signal strength of the second network meets the voice quality requirement of the IMS voice service.
Different from the scheme of directly switching the IMS voice service to the second network under the condition that the signal strength of the first network is poor, in the embodiment of the present application, when the service quality of the IMS voice service on the first network does not meet the voice quality requirement, the mobile terminal further determines whether the network signal strength of the second network meets the voice quality requirement of the IMS voice service.
The quality of service of the IMS voice service on the first network may be the same as the quality of service of the IMS voice service on the second network, or the quality of service of the IMS voice service on the first network may be different from the quality of service of the IMS voice service on the second network.
S203, if the network signal intensity of the second network meets the voice quality requirement of the IMS voice service, the mobile terminal switches the IMS voice service from the first network to the second network.
Optionally, the first network is a cellular network and the second network is a WLAN; alternatively, the first network is a WLAN and the second network is a cellular network. It can be understood that the embodiments of the present application are not limited to bidirectional seamless handover between VoLTE and volwifi, but may also be bidirectional seamless handover between other types of cellular networks and WLAN. That is, the cellular network is an LTE network, and the WLAN is a WIFI network, which is only an alternative.
The condition for switching the mobile terminal from the first network to the second network in the embodiment of the application includes: the service quality of the IMS voice service on the first network does not meet the voice quality requirement, and meanwhile, the network signal strength of the second network meets the voice quality requirement of the IMS voice service.
In the embodiment of the application, when the mobile terminal accesses the first network to perform the IMS voice service, and when it is determined that the service quality of the IMS voice service on the first network does not meet the voice quality requirement, the IMS voice service is not directly switched to the second network, but it is necessary to further determine whether the signal strength of the second network can meet the voice quality requirement of the IMS voice service. And under the condition that the signal intensity of the second network can meet the voice quality requirement of the IMS voice service, switching the IMS voice service to the second network. Therefore, compared with the scheme of directly switching the IMS voice service to the second network under the condition of poor signal strength of the first network, the embodiment of the application at least can ensure that the voice service quality of the IMS voice service in the switched second network does not become poor, thereby ensuring the continuity of the IMS voice service to a certain extent and meeting the voice service quality requirement of a user.
In the foregoing embodiment, in an implementation manner, the determining whether the service quality of the IMS voice service on the first network meets the voice quality requirement may include: determining a quality parameter of an IMS voice service on a first network; and determining whether the service quality of the IMS voice service on the first network meets the voice quality requirement or not according to the quality parameter. Optionally, the quality parameter may include at least one of packet loss rate, delay, jitter, and the like.
Further, the determining whether the service quality of the IMS voice service on the first network meets the voice quality requirement according to the quality parameter may include: determining whether the quality parameter is greater than or equal to a preset threshold; and if the quality parameter is greater than or equal to the preset threshold value, determining that the service quality of the IMS voice service on the first network does not meet the voice quality requirement.
Illustratively, the quality parameter includes a packet loss rate. At this time, the determining the quality parameter of the IMS voice service on the first network may include: determining the number of received data packets within a preset time range, and determining the packet loss rate of the IMS voice service on the first network according to the number of the received data packets and the number of data packets to be received. For example, in a preset time length range, the number of data packets sent to the mobile terminal by the network device (the number of data packets that the mobile terminal should receive) is x, and the number of data packets received by the mobile terminal is y, where the packet loss rate of the first network in the preset time length range may be represented as: (x-y)/x.
Alternatively, the quality parameter includes a packet loss rate. At this time, the determining the quality parameter of the IMS voice service on the first network may include: determining the number of lost data packets within a preset time range, and determining the packet loss rate of the IMS voice service on the first network according to the number of the lost data packets and the number of data packets to be connected. For example, in a preset time length range, the number of data packets sent to the mobile terminal by the network device (the number of data packets that the mobile terminal should receive) is x, and the number of data packets lost by the mobile terminal is z, at this time, the packet loss rate of the first network in the preset time length range may be represented as: z/x. If all other conditions are the same, z is x-y.
In practical application, the mobile terminal is in the IMS voice service process, where the type of the data packet transmitted between the mobile terminal and the network device may be an RTP packet, that is, the protocol adopted by the data packet is RTP. Through the identification of the RTP packet, the mobile terminal can determine the number of the data packets which should be currently received, the number of the lost data packets and the number of the received data packets. For example, the network device sends a data packet 1, a data packet 2, … …, and a data packet N to the mobile device, where the identifiers carried in the data packets are: 1. 2, … …, N; the mobile device can determine the number of lost data packets, the number (N) of data packets to be received and the number of received data packets according to the identification carried in the received data packets.
In the above implementation manner, when the mobile terminal accesses the first network to perform the IMS voice service, and when it is determined whether the service quality of the IMS voice service on the first network meets the voice quality requirement, specifically by determining the quality parameter of the IMS voice service on the first network, according to the quality parameter. When the service quality of the IMS voice service on the first network does not meet the voice quality requirement (for example, the delay time of the IMS voice service on the first network is long, or the packet loss rate is high, or the jitter is high), it is further determined whether the signal strength of the second network can meet the voice quality requirement of the IMS voice service. And under the condition that the signal intensity of the second network can meet the voice quality requirement of the IMS voice service, switching the IMS voice service to the second network. Therefore, the implementation mode can ensure that the voice service quality of the IMS voice service in the switched second network does not become poor, thereby ensuring the continuity of the IMS voice service to a certain extent and meeting the voice service quality requirement of a user.
In another implementation, the determining whether the service quality of the IMS voice service on the first network meets the voice quality requirement may include: determining a network signal strength of a first network; and determining whether the service quality of the IMS voice service on the first network meets the voice quality requirement or not according to the network signal strength of the first network. The implementation manner is different from the scheme of directly switching the IMS voice service to the second network under the condition that the signal strength of the first network is poor: in this implementation manner, according to the network signal strength of the first network, it is determined whether the service quality of the IMS voice service on the first network meets the voice quality requirement, but the voice quality requirement is not poor signal strength of the first network, and may be, as described above, low delay, small jitter, and the like.
In some embodiments, the determining whether the quality of service of the IMS voice service on the first network meets the voice quality requirement according to the network signal strength of the first network may include: determining whether the network signal strength of the first network is less than or equal to a preset signal strength threshold; and if the network signal intensity of the first network is less than or equal to the preset signal intensity threshold value, determining that the service quality of the IMS voice service on the first network does not meet the voice quality requirement.
In other embodiments, the determining whether the quality of service of the IMS voice service on the first network meets the voice quality requirement according to the network signal strength of the first network may include: determining whether the network signal strength of the first network within a preset time length is less than or equal to a preset signal strength threshold value; and if the network signal intensity of the first network in the preset time is less than or equal to the preset signal intensity threshold, determining that the service quality of the IMS voice service on the first network does not meet the voice quality requirement. This embodiment differs from the above embodiment in that: in this embodiment, a comparison between a duration in which the network signal strength of the first network is less than or equal to the preset signal strength threshold and the preset duration is added, and if the duration in which the network signal strength of the first network is less than or equal to the preset signal strength threshold exceeds the preset duration, it is determined that the service quality of the IMS voice service on the first network does not meet the voice quality requirement.
In the above implementation manner, when the mobile terminal accesses the first network to perform the IMS voice service, and when it is determined whether the service quality of the IMS voice service on the first network meets the voice quality requirement, specifically by determining the network signal strength of the first network, according to the network signal strength of the first network. When the service quality of the IMS voice service on the first network does not meet the voice quality requirement (for example, the network signal strength of the first network is less than or equal to the preset signal strength threshold), it is further determined whether the signal strength of the second network can meet the voice quality requirement of the IMS voice service. And under the condition that the signal intensity of the second network can meet the voice quality requirement of the IMS voice service, switching the IMS voice service to the second network. Therefore, the implementation mode can ensure that the voice service quality of the IMS voice service in the switched second network does not become poor, thereby ensuring the continuity of the IMS voice service to a certain extent and meeting the voice service quality requirement of a user.
On the basis of the foregoing embodiment, the determining whether the network signal strength of the second network meets the voice quality requirement of the IMS voice service may include: acquiring the network signal intensity of a second network; and if the network signal intensity of the second network is greater than or equal to the network signal intensity of the first network, determining that the network signal intensity of the second network meets the voice quality requirement of the IMS voice service. In the scheme, when the mobile terminal accesses the first network to perform the IMS voice service, and when the service quality of the IMS voice service on the first network is determined not to meet the voice quality requirement, the IMS voice service is not directly switched to the second network, but whether the signal strength of the second network can meet the voice quality requirement of the IMS voice service is further judged. And when the network signal intensity of the second network is greater than or equal to the network signal intensity of the first network, determining that the network signal intensity of the second network meets the voice quality requirement of the IMS voice service, and switching the IMS voice service to the second network.
Optionally, the determining whether the network signal strength of the second network meets the voice quality requirement of the IMS voice service may include: acquiring the network signal intensity of a second network; and if the network signal intensity of the second network is greater than or equal to the minimum network signal intensity required by meeting the voice quality requirement of the IMS voice service, determining that the network signal intensity of the second network meets the voice quality requirement of the IMS voice service. In the scheme, when the mobile terminal accesses the first network to perform the IMS voice service, and when the service quality of the IMS voice service on the first network is determined not to meet the voice quality requirement, the IMS voice service is not directly switched to the second network, but whether the signal strength of the second network can meet the voice quality requirement of the IMS voice service is further judged. And when the network signal intensity of the second network is greater than or equal to the minimum network signal intensity required by meeting the voice quality requirement of the IMS voice service, determining that the network signal intensity of the second network meets the voice quality requirement of the IMS voice service, and switching the IMS voice service to the second network.
Therefore, compared with the scheme of switching the IMS voice service to the second network under the condition that the signal strength of the first network is poor, the embodiment at least can ensure that the voice service quality of the IMS voice service in the switched second network does not become poor, thereby ensuring the continuity of the IMS voice service to a certain extent and meeting the voice service quality requirement of the user.
Further, the network signal strength may include any one of the following network parameters:
received Signal Strength Indication (RSSI);
reference Signal Receiving Power (RSRP);
reference Signal Receiving Quality (RSRQ for short);
Signal-to-Noise Ratio (SNR);
and so on.
The specific meaning of the network parameters may refer to related technologies, which are not described herein again. The minimum network signal strength corresponding to different network signal strengths and/or the preset signal strength threshold value corresponding to different network signal strengths may be set according to historical experience and/or actual conditions, which is not limited in the embodiments of the present application.
It should be noted that different network signal strengths may correspond to different minimum network signal strengths and/or different network signal strengths may correspond to different preset signal strength thresholds. For example, in a cellular network, the lowest network signal strength for RSSI is different from the lowest network signal strength for RSRP; as another example, the lowest network signal strength for RSSI is different from the lowest network signal strength for SNR; as another example, the lowest network signal strength for RSRP is different from the lowest network signal strength for SNR; and so on.
In addition, for the same network signal strength, the preset signal strength threshold corresponding to the first network and the preset signal strength threshold corresponding to the second network may be different; and/or, for the same network signal strength, the lowest network signal strength corresponding to the first network may be different from the lowest network signal strength corresponding to the second network. For example, the preset signal strength threshold corresponding to the RSSI of the first network may be different from the preset signal strength threshold corresponding to the RSSI of the second network, and so on.
