For the 5G independent networking mode, the 3GPP proposes two schemes, namely, 5G new air interface voice-over-carrier (VoNR, voice Over New Radio) and evolved packet system (EPS, evolved Packet System) Fallback (Fallback). The VoNR scheme refers to providing voice service based on an IP multimedia subsystem (IMS, IP Multimedia Subsystem) by the 5G access network and the core network, and the EPS Fallback scheme refers to dropping 4G when the terminal initiates an IMS call on the 5G network, and the VoLTE voice service is established through the 4G access network and the core network, where the dropping mode may be handover or the like.
The inter-system measurement in the EPS Fallback scheme is performed after the signaling process of the call, namely the time delay of the EPS Fallback scheme comprises the signaling time delay of the 5G call, the inter-system measurement time delay, the time delay of the fall-back to 4G and the time delay of the VoLTE call establishment process; the inter-system measurement time delay is longer, so that the time delay of the whole EPS Fallback voice service establishment is longer, and the user experience is affected.

The measuring method for voice call-back and call-forth in the embodiment is applied to network equipment, wherein the network equipment is network equipment in a communication system; in this embodiment, the communication system is, for example, a 5G system. Here, the communication system applicable to the embodiment is a communication system adopting a 5G independent networking scheme, and the independent networking scheme is specifically an EPS Fallback scheme, that is, for a voice service, when a terminal initiates an IMS call on a 5G network, the terminal falls back to a 4G network, and performs the voice service through a 4G access network and a core network.
Wherein the network device may be a device in communication with a terminal, the network device may provide communication coverage for a particular geographical area, and may communicate with terminal devices located within the coverage area. Alternatively, the network device may be an NR base station or a 5G base station in a 5G system. In the following embodiments, a network device is taken as an example of a base station (NR base station or 5G base station).
In an embodiment, the receiving the first RRC message for voice traffic from the terminal includes: and receiving an RRC connection establishment request message of the terminal, wherein the RRC connection establishment request message carries a cause value representing the voice service.
In this embodiment, the terminal actively initiates a call request in an idle state, or after receiving a paging message as a called party, sends an RRC connection establishment request (RRC Connection Request) message to the base station, where the cause value carried by the RRC connection establishment request message may be "voice", indicating that the RRC connection establishment request message is used for voice service.
In this embodiment, a base station receives an RRC connection establishment request message sent by a terminal, determines that the request is a voice service according to a cause value carried in the RRC connection establishment request message, and determines to initiate a voice call back and forth for the voice service according to semantic scheme capability supported by the base station itself; wherein the voice call-in and call-out is a voice call-in and call-out for a 5G system, and as an example, the voice call-in and call-out may be an EPS Fallback scheme.
As an implementation manner, if the base station only supports the EPS Fallback scheme, the base station determines to initiate a voice call back for the voice service according to the voice scheme supported by the base station, i.e. initiates the EPS Fallback. If the base station supports other voice schemes in addition to the EPS Fallback scheme, the base station may determine, based on the relevant configuration information, that a voice call-in-call for the voice service needs to be initiated, that is, the EPS Fallback is initiated.
In this embodiment, the base station sends a second RRC message to the terminal, where the second RRC message carries an inter-system measurement field, and the inter-system measurement field is used for the terminal to perform inter-system measurement; that is, the present application advances the inter-system measurement procedure to the signaling interaction procedure of the origination call in the 5G communication system, that is, the Service Request (Service Request) procedure.

As a third embodiment, the base station may also send the inter-system measurement field through other independent RRC signaling different from the above RRC signaling; however, it should be noted that the RRC signaling is sent during the origination process, that is, the base station can obtain the inter-system measurement report of the terminal before the origination process is completed.
In the embodiment of the invention, the inter-system measurement field comprises measurement configuration information based on a measurement interval, so that the terminal performs inter-system measurement in the measurement interval and performs signaling transmission in a non-measurement interval; or the inter-system measurement field comprises measurement configuration information based on no measurement interval, so that the terminal performs signaling transmission while performing inter-system measurement.
In an embodiment, the method further comprises: and receiving a different system measurement report of the terminal, selecting a cell to be switched according to the different system measurement report, and executing voice call-back and call-back based on the cell to be switched, switching or redirecting to the cell to be switched.

As an example, taking the second RRC message as an RRC connection setup message, an example of a code carrying a different system measurement field in the RRC connection setup message may be as follows:
where "measConfig" represents a heterogeneous system measurement field.
By adopting the technical scheme of the embodiment of the invention, aiming at the scene of executing the voice call-in-call-out scheme, the front-end different system measurement is carried out, and the different system measurement is carried out particularly in the call-in signaling process, thereby greatly shortening the time delay of the voice call-in-call-out process and improving the user experience.
The embodiment of the invention also provides a measuring method for the voice call-in and call-out. FIG. 2 is a flow chart of another method for measuring voice call-back and call-forth according to an embodiment of the invention; as shown in fig. 2, the method includes:
step 201: a first RRC message for voice traffic is sent to the network device.
Step 202: and receiving a second RRC message of the network equipment, wherein the second RRC message comprises a different system measurement field.
Step 203: and executing the inter-system measurement according to the inter-system measurement field, obtaining an inter-system measurement report, and sending the inter-system measurement report to the network equipment.
The method for measuring the voice call-back and call-forth in the embodiment is applied to a terminal, wherein the terminal is a terminal in a communication system, and the terminal can be located in the coverage area of network equipment; in this embodiment, the communication system is, for example, a 5G system. Examples of terminals include, but are not limited to, handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in 5G networks or terminal devices in future evolved PLMNs, etc., as an example, the terminal may be a cell phone.
As an embodiment, the sending, to the network device, a first RRC message for voice traffic includes: an RRC connection setup request (RRC Connection Request) message is sent to the network device, the RRC connection setup request message carrying a cause value characterizing the voice traffic.
In this embodiment, the terminal actively initiates a call request in an idle state, or after receiving a paging message as a called party, sends an RRC connection establishment request message to the base station, where the cause value carried by the RRC connection establishment request message may be "voice", which indicates that the RRC connection establishment request message is used for voice service.
As an embodiment, the receiving the second RRC message of the network device includes: receiving an RRC connection establishment message of the network equipment, wherein the RRC connection establishment message comprises a different system measurement field; or, receiving an RRC connection reconfiguration message of the network device; the RRC connection reconfiguration message comprises a different system measurement field; or, receiving RRC signaling of the network device; the RRC signaling includes a foreign system measurement field.
As a first embodiment, the terminal receives an RRC connection setup (RRC Connection Setup) message; the RRC connection setup message is received after the RRC connection setup request message is sent; the RRC connection setup message carries a different system measurement field.
As a second embodiment, in the origination process, after RRC connection setup is completed, the terminal receives an RRC connection reconfiguration (RRC Connection Reconfiguration) message; the RRC connection reconfiguration message carries a different system measurement field.
As a third embodiment, the base station may also send the different system measurement field through other independent RRC signaling different from the above RRC signaling, and the terminal receives the RRC signaling; however, it should be noted that the RRC signaling is received during the origination process, that is, the base station can obtain the inter-system measurement report of the terminal before the origination process is completed.
In this embodiment, the inter-system measurement field includes measurement configuration information based on a measurement interval, and the performing inter-system measurement according to the inter-system measurement field includes: the terminal performs different system measurement in the measurement interval and performs signaling transmission in the non-measurement interval; alternatively, the inter-system measurement field includes measurement configuration information based on no measurement Gap (no Gap), and the performing the inter-system measurement according to the inter-system measurement field includes: the terminal performs signaling transmission while performing inter-system measurement.
As a first embodiment, for inter-system measurements based on measurement intervals, the terminal performs inter-system measurements in the measurement intervals and signaling transmissions in non-measurement intervals. As a second embodiment, for inter-system measurements based on no measurement intervals, the terminal may continuously measure, i.e. signaling may be performed while the inter-system measurements are performed.
In this embodiment, after the terminal performs the inter-system measurement, the terminal sends an inter-system measurement report to the network device. As an example, the terminal may periodically make inter-system measurements and send inter-system measurement reports to the network device.
By adopting the technical scheme of the embodiment of the invention, aiming at the scene of executing the voice call-in-call-out scheme, the front-end different system measurement is carried out, and the different system measurement is carried out particularly in the call-in signaling process, thereby greatly shortening the time delay of the voice call-in-call-out process and improving the user experience.
The following describes a method for measuring voice call-back and call-forth in detail according to an embodiment of the present invention with reference to a specific example.
FIG. 3 is a flow chart of a method for measuring a voice call-back in accordance with an embodiment of the present invention; as shown in fig. 3, includes:
step 301: the User Equipment (UE) sends AN RRC connection request message to the (Radio) Access Network. As AN example, the (R) AN may specifically be a base station, such as a 5G base station or AN NR base station, which are denoted by the base station in the following description.
Here, the cause value carried by the RRC connection request message is "voice", indicating that the RRC connection establishment request message is for voice service. The base station judges that the voice service is the reason value carried in the RRC connection establishment request message, and then determines to initiate the voice call-in and call-out aiming at the 5G system according to the semantic scheme capability supported by the base station.
Step 302: the base station sends an RRC connection establishment message to the UE; the RRC connection setup message carries a different system measurement field.
Step 303: the UE sends an RRC connection establishment completion message to the base station; the RRC connection setup complete message carries the relevant NAS signaling.
Step 304: the base station sends an N2Message (N2 Message) to an access and mobility management function (AMF, access and Mobility Management Function); the N2message carries NAS signaling for the service request.
In a subsequent procedure, a security-based authentication procedure is performed between the UE and the AMF and between the AMF and a session management function (SMF, session Management Function); after authentication is completed, the AMF and SFM previously establish a protocol data unit (PDU, protocol Data Unit) Session (Session) link through a signaling interaction request.
Step 305: the AMF sends an N2Request (N2 Request) message to the base station.
Step 306: the base station transmits an RRC connection reconfiguration message to the UE.
Step 307: the UE sends an RRC connection reconfiguration complete message to the base station.
Step 308: the base station sends an N2Request acknowledgement (N2 Request ACK) message to the AMF.
Step 309: the UE sends a different system measurement report to the base station. After receiving the inter-system measurement field, the UE performs inter-system measurement based on the inter-system measurement field.
As an example, the inter-system measurement field includes measurement configuration information based on a measurement interval in which the terminal performs inter-system measurement and in which signaling is transmitted; as another example, the inter-system measurement field includes measurement configuration information based on no measurement interval, and the terminal performs signaling transmission while performing the inter-system measurement. After the measurement of the different system is completed, sending a measurement report of the different system to the base station; wherein, the inter-system measurement report may include all 4G cells obtained by terminal measurement and corresponding related parameters (the related parameters may include parameters representing channel quality); or, the different system measurement report can also be a 4G cell with the best channel quality obtained by terminal measurement. The base station needs to execute EPS Fallback, and may select the 4G cell with the best channel quality from the inter-system measurement report to execute cell handover or redirection.
In the subsequent procedure, the AMF establishes a PDU Session (Session) link with the SFM previously through signaling interactions.
In this embodiment, the description is given taking the case that the RRC connection establishment message carries the inter-system measurement field as an example, and currently, the inter-system measurement field may be carried in the RRC connection reconfiguration message, or the inter-system measurement field may be carried in other independent RRC signaling different from the RRC signaling, where the sending timing of the RRC signaling may be any timing before the PDU session link is established.
FIG. 4 is a schematic diagram of the interaction of voice call-back and call-forth in the prior art; fig. 4 is a signaling interaction flow of an origination call, that is, a Service Request (Service Request) procedure, which is different from that shown in fig. 3 in this application, in that an RRC message (e.g., an RRC connection setup message) does not carry an inter-system measurement field, and correspondingly, in this process, the terminal does not perform inter-system measurement and report a measurement report. This procedure is used to establish a quality of service (QoS) flow of class 5 to carry session initiation protocol (SIP, session Initiation Protocol) signaling, in particular:
the UE sends a SIP signaling request (Invite) to the IMS, which, after receiving the SIP signaling request, informs the core network to prepare to establish a bearer, and the core network instructs the base station to establish a QoS flow with a level 1 for carrying voice traffic.
If the base station selects the EPS Fallback scheme, the QoS flow for establishing the voice service is refused to be established, and the EPS Fallback process is executed. The base station firstly triggers the different system measurement process, issues measurement control information to instruct the terminal to conduct 4G measurement, and selects a 4G cell according to the measurement result after the terminal reports the 4G measurement report. It follows that the prior art inter-system measurements are performed after the signaling procedure of the originating call.
The base station performs a handover/redirection procedure to the selected 4G cell, after which the terminal completes the VoLTE call setup on 4G.
From the above, the EPS Fallback voice service setup delay from the idle state includes signaling delay of 5G origination + inter-system measurement delay + fall-back to 4G delay + VoLTE call setup delay.
On the other hand, the time delay of the inter-system measurement is longer.
As an example, for measurement interval based inter-system measurement, assuming that the measurement interval repetition period (MGRP, measurement Gap Repetition Period) is a minimum (e.g. 20 ms), the measurement interval length (MGL, measurement Gap Length) is 6ms, and since 6ms is required to measure one 4G frequency point, i.e. one 4G frequency point is measured in one measurement interval repetition period, on average, 4G frequency points are to be measured, and each frequency point is to be measured 5 times, the inter-system measurement delay is 20×4×5=400 ms.
As another example, for a different system measurement based on no measurement interval, referring to the above assumption, the different system measurement delay is 6×4×5=120 ms since continuous measurement is possible.
By adopting the measurement scheme of the embodiment of the invention, because the inter-system measurement is pre-arranged, namely the inter-system measurement is carried out in the signaling interaction process of the call initiation, the EPS Fallback voice service establishment delay comprises the signaling delay (new) +the delay of the call initiation of 5G (new) +the delay of the call back to 4 G+VoLTE call establishment delay.
As a first embodiment, for the inter-system measurement based on the measurement interval, the above assumption is still adopted, and the inter-system measurement delay is 400ms, so that the signaling delay (new) of the 5G origination is the maximum of 200 and 400, that is, 400ms, and thus the EPS Fallback voice service setup delay is shortened by 200+400-400=200 ms.
As another embodiment, for the inter-system measurement based on no measurement interval, referring to the assumption that the introduced inter-system measurement delay is 120ms, the signaling delay (new) of the 5G origination is the maximum of 200 and 120, i.e. 200ms, so the EPS Fallback voice service setup delay is shortened by 200+120-200=120 ms.
Therefore, the technical scheme of the application greatly shortens the time delay of the voice calling-back and calling-back process, and improves the user experience.
