Description

Voice call processing method, terminal, network side equipment and storage medium
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a voice call processing method, a terminal, a network device, and a storage medium.
Background
At the initial stage of 5G network business, when there is no continuous NR (New Radio, New air interface) coverage but an operator already owns a mature LTE (Long Term Evolution) business network, an EPS FB (Evolved Packet System Fallback) voice scheme is often used for voice call. Common EPS FB speech schemes include measurement-based handover, blind handover and blind redirection.
In the measurement-based EPS FB scheme process, when the base station receives a voice request of the terminal, in order to determine a target LTE base station, the base station issues a B1 measurement to the terminal, so that the terminal starts signal measurement on LTE, and reports a measurement result. Then, the base station can start switching to the LTE network according to the measurement result reported by the terminal.
However, a certain time interval is caused from the time when the terminal starts the inter-system measurement of the LTE signal to the time when the measurement result is successfully reported, and then the base station issues the inter-system handover command to the terminal, so that the time delay from the time when the terminal starts to call to the time when the terminal is connected is too long.
Therefore, how to reduce the delay caused by inter-system measurement in the EPS FB process is a technical problem that needs to be solved in the present industry.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in each embodiment of the present invention, if words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and actions, those skilled in the art can understand that the words such as "first" and "second" do not limit the quantity and execution order.
Fig. 1 is a schematic flow chart of an EPS FB method in the prior art. As shown in fig. 1, a flow of an EPS FB in the prior art includes:
step 1: UE sends a voice call request to a base station;
step 2: the base station sends out a different system B1 measurement to the UE;
and step 3: the UE reports the measurement result of the different system B1;
and 4, step 4: the base station sends a different system switching instruction to the UE according to the received B1 measurement result;
and 5: and the UE is switched to the LTE network according to the received inter-system switching instruction.
As can be seen from the above steps, after the UE initiates the voice call request to the base station and before receiving the inter-system handover command sent by the base station, the process of performing inter-system measurement and reporting is also included in the middle. The time delay brought by the process has a great influence on services with high requirements on time delay, such as voice services, and the call experience of the user on the 5G network is directly influenced.
Aiming at the technical problem of long time delay in the EPS FB process in the prior art, the voice call processing method, the terminal, the network side device and the storage medium provided by the embodiment of the invention can be used for acquiring the different system measurement information from the terminal before the terminal initiates the voice call request, so that the step of different system measurement is omitted in the EPS FB process, and the EPS FB time delay is shortened.
Fig. 2 is a flowchart illustrating a voice call processing method according to an embodiment of the present invention. As shown in fig. 2, the method includes:
s201, receiving first measurement indication information sent by a network side device, and performing inter-system measurement based on the first measurement indication information to obtain inter-system measurement information.
The network device may specifically be, for example, a base station, such as a gNB, and this is not specifically limited in the embodiment of the present invention.
Specifically, in order to avoid performing inter-system measurement in the EPS FB process, the network side device may send first measurement indication information to the served terminal, and instruct the terminal to perform inter-system measurement based on the first measurement indication information, so as to obtain inter-system measurement information, for example, the inter-system measurement is measurement for an LTE system, and correspondingly, the inter-system measurement information is LTE system measurement information. The inter-system measurement information may be, for example, Signal strength information of an LTE Signal, such as RSRP (Reference Signal Receiving Power), or SINR (Signal to Interference plus Noise Ratio) of the LTE Signal, and what kind of information of the inter-system is specifically collected may be determined based on input parameters required by the network side device to determine an algorithm for the inter-system target handover cell, which is not particularly limited in the embodiment of the present invention.
S202, feeding back the inter-system measurement information to the network side equipment.
Specifically, after the terminal performs inter-system measurement based on the first measurement indication information, the measured inter-system measurement information is fed back to the network side device. Correspondingly, after receiving the inter-system measurement information fed back by the terminal, the network side device correspondingly stores the inter-system measurement information in the location of the terminal, such as context information, so that when EPS FB needs to be initiated for the terminal, a target inter-system cell can be determined based on the stored inter-system measurement information.
S203, after sending a voice call request to the network side equipment, receiving a different system switching instruction sent by the network side equipment; the inter-system switching instruction is sent by the network side equipment based on the received and stored inter-system measurement information.
Specifically, the terminal sends a voice call request to the network side device when a voice call needs to be initiated. Accordingly, after receiving the voice call request, the network side device forwards the request to the core network for processing, where the processing flow of the core network is the same as that in the prior art, and details of this process are not repeated in this embodiment of the present invention.
When receiving a request for increasing a voice Qos Flow (Quality of service Flow) sent by a core network in response to a voice call request of a terminal, a network side device may determine a target inter-system cell according to the inter-system measurement information acquired and stored in advance, and send an inter-system handover instruction to the terminal based on the determined target inter-system cell. The step of confirming the target inter-system cell according to the pre-acquired and stored inter-system measurement information may be when a request of a voice Qos Flow is received, or may be at other occasions.
According to the voice call processing method provided by the embodiment of the invention, the different system measurement information is acquired from the terminal before the terminal initiates the voice call request, so that the step of different system measurement is omitted in the EPS FB process, and the EPS FB time delay is shortened. Besides, the configuration and reporting of the inter-system measurement B1 event in the prior art are reduced, and the signaling overhead is also reduced.
On the basis of the foregoing embodiment of the present invention, the first measurement indication information is sent by the network side device when the terminal accesses or switches to the network side device.
It can be understood that, in order to ensure that the terminal has corresponding inter-system measurement information stored in the network-side device when initiating the voice call, the first measurement indication information needs to be sent to the terminal as soon as possible, so that the terminal starts the inter-system measurement procedure as soon as possible. Based on this, the network side device may send the first measurement indication information to the terminal when the terminal accesses or switches to the network side device.
According to the voice call processing method provided by the embodiment of the invention, the network side equipment can obtain the different system measurement information earlier by sending the first measurement indication information to the terminal when the terminal is initially accessed or switched to the network side equipment, so that the terminal can be ensured not to carry out different system measurement in the process of initiating the EPS FB even when the terminal is just accessed to the network side equipment, and the time delay of the EPS FB process is reduced.
On the basis of the above embodiment of the present invention, the first measurement indication information is used to indicate the terminal to perform periodic inter-system measurement and inter-system measurement information feedback;
correspondingly, the performing inter-system measurement based on the first measurement indication information, and the feeding back the inter-system measurement information to the network side device include:
and performing periodic inter-system measurement and feedback of the inter-system measurement information based on the first measurement indication information.
Specifically, due to factors such as mobility of the terminal and changes of the external environment, the wireless environment in which the terminal is located often changes dynamically, and accordingly, different system measurement information measured by the terminal at different times often differs. Therefore, in order to ensure that the inter-system measurement information based on the network side device better conforms to the current wireless environment state of the terminal in the EPS FB process, the first indication information sent to the terminal in the embodiment of the present invention is used to indicate the terminal to perform periodic inter-system measurement and inter-system measurement information feedback.
Due to the adoption of periodic inter-system measurement and inter-system measurement information feedback, the embodiment of the invention ensures that the network side equipment can acquire the related conditions of inter-system signals in the wireless environment where the network side equipment is currently located in real time or nearly real time, thereby ensuring that the accuracy and reliability of the based inter-system measurement information can be ensured even if the inter-system measurement triggered based on the call event is not carried out in the EPS FB process.
On the basis of the foregoing embodiment of the present invention, before the receiving the inter-system handover instruction sent by the network side device, the method further includes:
receiving second measurement indication information sent by the network side equipment, wherein the second measurement indication information is sent when the network side equipment does not receive the inter-system measurement information or the received inter-system measurement information is invalid;
and performing inter-system measurement based on the second measurement indication information, and feeding back inter-system measurement information.
Specifically, when the terminal initiates the voice call request, the network side device may not have sent the first measurement indication information to the terminal, and at this time, the network side device does not store corresponding inter-system measurement information. In addition, due to the influence of factors such as a wireless environment, the terminal may perform inter-system measurement and feed back the inter-system measurement information, but the network side device may not successfully receive the inter-system measurement information. It can be understood that, in addition to the above cases, there are other cases that cause the network side device to receive the inter-system measurement information or to invalidate the received inter-system measurement information, and this is not exhaustive in the embodiments of the present invention.
Accordingly, since there are various situations that may cause the network side device not to receive the inter-system measurement information or the received inter-system measurement information to be invalid before the terminal initiates the voice call request, in order to ensure smooth EPS FB under such a situation, the network side device in the embodiment of the present invention may send second measurement indication information to the terminal before the inter-system handover instruction needs to be sent to the terminal, so that the terminal performs inter-system measurement based on the second measurement indication information and feeds back the inter-system measurement information.
The embodiment of the invention ensures the robustness of the method of the embodiment of the invention by setting a sending mechanism of the second measurement indication information.
On the basis of the above embodiment of the present invention, the first measurement indication information includes inter-system signal information to be measured;
correspondingly, the performing inter-system measurement based on the first measurement indication information includes:
and performing inter-system measurement on the inter-system signal information to be measured.
Specifically, when network configuration is performed, information related to inter-system signals having the same coverage area as the inter-system signals is configured and stored in the network side device. When the first measurement indication information needs to be sent to a terminal, the network side equipment fills the stored information of the inter-system signal as the inter-system signal information to be measured into the first measurement indication information, and sends the information to the terminal, so that the terminal can carry out targeted inter-system measurement based on the inter-system signal information to be measured.
Fig. 3 is a flowchart illustrating a voice call processing method according to another embodiment of the present invention, and as shown in fig. 3, the method includes:
s301, sending first measurement indication information to a terminal, enabling the terminal to carry out inter-system measurement based on the first measurement indication information, and feeding back inter-system measurement information.
The network device may specifically be, for example, a base station, such as a gNB, and this is not specifically limited in the embodiment of the present invention.
Specifically, in order to avoid performing inter-system measurement in the EPS FB process, the network side device may send first measurement indication information to the served terminal, and instruct the terminal to perform inter-system measurement based on the first measurement indication information, so as to obtain inter-system measurement information, for example, the inter-system measurement is measurement for an LTE system, and correspondingly, the inter-system measurement information is LTE system measurement information. The inter-system measurement information may be, for example, Signal strength information of an LTE Signal, such as RSRP (Reference Signal Receiving Power), or SINR (Signal to inter Signal plus Noise Ratio) of the LTE Signal, and what kind of information of the inter-system is specifically collected may be determined based on input parameters required by the network side device to determine an algorithm for switching the inter-system target cell, which is not particularly limited in the embodiment of the present invention.
Correspondingly, after receiving the first measurement indication information, the terminal performs inter-system measurement based on the first measurement indication information, and feeds back the inter-system measurement information obtained through measurement to the network side device.
And S302, receiving and storing the different system measurement information fed back by the terminal.
Specifically, after receiving the inter-system measurement information fed back by the terminal, the network side device correspondingly stores the inter-system measurement information in a location, such as context information, of the terminal, so that when EPS FB needs to be initiated for the terminal, a target inter-system cell can be determined based on the stored inter-system measurement information.
And S303, when the terminal initiates a voice call, sending a different system switching instruction to the terminal based on the stored different system measurement information.
Specifically, the terminal sends a voice call request to the network side device when a voice call needs to be initiated. Accordingly, after receiving the voice call request, the network side device forwards the request to the core network for processing, where the processing flow of the core network is the same as that in the prior art, and details of this process are not repeated in this embodiment of the present invention.
When a request for increasing voice Quality of Flow (QoS Flow) sent by a core network in response to a voice call request of a terminal is received, a network side device confirms a target inter-system cell according to the inter-system measurement information which is acquired and stored in advance, and sends an inter-system handover instruction to the terminal based on the determined target inter-system cell. The step of confirming the target inter-system cell according to the pre-acquired and stored inter-system measurement information may be when a request of a voice Qos Flow is received, or may be at other occasions.
According to the voice call processing method provided by the embodiment of the invention, the different system measurement information is acquired from the terminal before the terminal initiates the voice call request, so that the step of different system measurement is omitted in the EPS FB process, and the EPS FB time delay is shortened. In addition, the configuration and reporting of the inter-system measurement B1 event in the prior art are reduced, and the signaling overhead is also reduced.
On the basis of the above embodiment of the present invention, the sending the first measurement indication information to the terminal includes:
and when the terminal is accessed to network side equipment or switched to the network side equipment, the first measurement indication information is sent to the terminal.
It can be understood that, in order to ensure that when the terminal initiates a voice call, the network-side device has corresponding inter-system measurement information stored therein, the first measurement indication information needs to be sent to the terminal as soon as possible, so that the terminal starts the inter-system measurement procedure as soon as possible. Based on this, the network side device may send the first measurement indication information to the terminal when the terminal accesses or switches to the network side device.
According to the voice call processing method provided by the embodiment of the invention, the network side equipment can obtain the different system measurement information earlier by sending the first measurement indication information to the terminal when the terminal is initially accessed or switched to the network side equipment, so that the terminal can be ensured not to carry out different system measurement in the process of initiating the EPS FB even when the terminal is just accessed to the network side equipment, and the time delay of the EPS FB process is reduced.
On the basis of the above embodiment of the present invention, the first measurement indication information is used to indicate that the terminal periodically performs inter-system measurement and inter-system measurement information feedback.
Correspondingly, the performing inter-system measurement based on the first measurement indication information and the feeding back the inter-system measurement information to the network side device include:
and performing periodic inter-system measurement and feedback of the inter-system measurement information based on the first measurement indication information.
Specifically, due to factors such as mobility of the terminal and changes of the external environment, the wireless environment in which the terminal is located often changes dynamically, and accordingly, different system measurement information measured by the terminal at different times often differs. Therefore, in order to ensure that the inter-system measurement information based on the network side device better conforms to the current wireless environment state of the terminal in the EPS FB process, the first indication information sent to the terminal in the embodiment of the present invention is used to indicate the terminal to perform periodic inter-system measurement and inter-system measurement information feedback.
Due to the adoption of periodic inter-system measurement and inter-system measurement information feedback, the embodiment of the invention ensures that the network side equipment can acquire the related conditions of inter-system signals in the wireless environment where the network side equipment is currently located in real time or nearly real time, thereby ensuring that the accuracy and reliability of the based inter-system measurement information can be ensured even if the inter-system measurement triggered based on the call event is not carried out in the EPS FB process.
On the basis of the foregoing embodiment of the present invention, when the terminal feeds back the inter-system measurement information multiple times based on the first measurement instruction information, the receiving and storing the inter-system measurement information fed back by the terminal includes:
and receiving the different-system measurement information, and replacing the locally-stored different-system measurement information with the currently-received different-system measurement information if the different-system measurement information fed back by the terminal before is locally stored.
Specifically, when the terminal feeds back the inter-system measurement information for multiple times based on the first measurement indication information, the recently fed-back inter-system measurement information can better reflect the current wireless environment and the inter-system signal condition of the terminal. Therefore, when the network side device receives new inter-system measurement information, if the inter-system measurement information fed back by the terminal before is locally stored, the locally stored inter-system measurement information is replaced by the currently received inter-system measurement information, so that the inter-system measurement information stored in the network side device is the latest inter-system measurement information.
The embodiment of the invention replaces the locally stored different system measurement information with the newly received different system measurement signal, so that the different system measurement information used in the EPS FB process is the latest different system measurement information, and the reliability of different system switching in the EPS FB process is ensured.
On the basis of the above embodiment of the present invention, when the terminal does not feed back the inter-system measurement information or the fed-back inter-system measurement information is invalid, the method further includes:
sending second measurement indication information to a terminal, enabling the terminal to carry out inter-system measurement based on the second measurement indication information, and feeding back inter-system measurement information;
and sending a different system switching instruction to the terminal based on the different system measurement information.
Specifically, when the terminal initiates the voice call request, the network side device may not have sent the first measurement indication information to the terminal, and at this time, the network side device does not store corresponding inter-system measurement information. In addition, due to the influence of factors such as a wireless environment, the terminal may perform inter-system measurement and feed back the inter-system measurement information, but the network side device may not successfully receive the inter-system measurement information. It can be understood that, in addition to the above cases, there are other cases that cause the network side device to receive the inter-system measurement information or to invalidate the received inter-system measurement information, and this is not exhaustive in the embodiments of the present invention.
Accordingly, since there are various situations that may cause the network side device not to receive the inter-system measurement information or the received inter-system measurement information to be invalid before the terminal initiates the voice call request, in order to ensure smooth EPS FB under such a situation, the network side device in the embodiment of the present invention may send second measurement indication information to the terminal before the inter-system handover instruction needs to be sent to the terminal, so that the terminal performs inter-system measurement based on the second measurement indication information and feeds back the inter-system measurement information.
The embodiment of the invention ensures the robustness of the method of the embodiment of the invention by setting a sending mechanism of the second measurement indication information.
On the basis of the above embodiment of the present invention, the first measurement indication information includes inter-system signal information to be measured.
Specifically, the inter-system signal to be measured refers to an inter-system signal having the same coverage area as the network side device. The network side equipment fills the inter-system signal information to be measured in the first measurement indication information and sends the inter-system signal information to be measured to the terminal, so that the terminal can perform targeted inter-system measurement based on the inter-system signal information to be measured
On the basis of the above embodiments of the present invention, the inter-system signal information to be measured is obtained from inter-system signal information in the local configuration information.
Specifically, when the network is configured, the network side device configures and stores therein information related to the inter-system signal having the same coverage as the inter-system signal. When the first measurement indication information needs to be sent to a terminal, the network side device may fill the stored information of the inter-system signal as information of the inter-system signal to be measured into the first measurement indication information, and send the information to the terminal.
On the basis of the above embodiment of the present invention, when the terminal initiates a voice call, sending a different system switching instruction to the terminal based on different system measurement information fed back by the terminal in advance includes:
and the terminal initiates a voice call and sends a different system switching instruction to the terminal based on the different system measurement information fed back by the terminal in advance when determining to perform EPS FB.
Specifically, whether to execute the EPS FB is determined based on the current network environment, network resources, and other factors, and when the current network side device is not enough to provide the voice service, the EPS FB is determined to be executed, and accordingly, the inter-system handover instruction is sent to the terminal based on the inter-system measurement information fed back by the terminal in advance. And when the current network side equipment is enough to ensure that the network service is provided for the terminal by itself, the network side equipment can provide the voice service for the terminal by itself without performing EPS FB.
The following describes a flow of the voice call processing method provided in the embodiment of the present invention by taking an example of configuring a terminal with periodic inter-system measurement on an LTE signal.
In the 3GPP (3rd Generation Partner Project, third Generation partnership Project) 38.331 protocol (Radio Resource Control (RRC) protocol specification), the definition of the event reporting and periodic reporting modes in section 5.5.5Measurement reporting is as follows:
“1>if there is at least one applicable neighbouring cell to report:
2>if the reportType is set to eventTriggered or periodical:
3>set the measResultNeighCells to include the best neighbouring cells up to maxReportCells in accordance with the following”
it can be seen from the above description that, regardless of whether inter-system period measurement or B1 event measurement is configured, the measurement result is reported in the measResultNeighCells field, therefore, the result reported by the period measurement can be used to replace the B1 event measurement result, and the base station can directly use the last inter-system period measurement result of the terminal to make the decision of inter-system handover, so as to omit steps 2 and 3 in fig. 1, and achieve the purpose of accelerating handover to the LTE network, and the specific flow is as follows:
step A: when a terminal is accessed to an NR base station for the first time or is switched to the NR base station, if there is an LTE network signal that covers the same as the NR base station, configuring inter-system period measurement using the LTE signal as a measurement object, where a specific flow is as shown in fig. 4;
and B: when the terminal reports the measurement result of the different systems, if the terminal successfully measures the signal of the LTE network, the base station stores the measurement result of the different systems this time or updates the stored result, and the specific flow is as shown in fig. 5;
and C: when the terminal initiates a voice call, if the base station stores the inter-system period measurement result, the result is directly used for replacing the B1 event measurement result to carry out switching judgment, if the result is valid, the base station directly sends a switching command to the LTE network to the terminal, and if the storage result is invalid or the judgment fails, the B1 event measurement is configured for the terminal according to the original EPS FB flow. The specific flow is shown in FIG. 6.
