The related technologies of the present application will be introduced firstly below.

1. EPS Fallback Mechanism

An important way for the 5G SA network to implement voice is EPS Fallback. Its main idea is to use 4G long-term evolution voice bearer (Voice over Long-Term Evolution, VoLTE) to complete the call when switching/redirecting to 4G during a call, and the call ends. Then quickly fall back to 5G.

Switch-based EPS Fallback

When a terminal with EPS Fallback capability initiates a voice service requirement, the NR issues LTE B1 measurement, and the terminal reports after meeting the B1 threshold. The NR side initiates a handover command to the LTE network, and the terminal performs voice services after switching to the LTE network.

The main steps are as follows:

Step S11, gNB sends B1 measurement to UE, carrying the 4G carrier frequency (frequency point) and B1 threshold to be measured in the measurement;

Step S12, the UE reports the measured B1 level of the LTE cell, the physical cell identifier (Physical Cell Identifier, PCI) and the measurement identifier (measid) of the cell to the gNB;

Step S13, the gNB sends a handover command to the UE, carrying the target cell frequency and PCI;

Step S14, establishing a dedicated bearer for voice services with a QoS Class Identifier (QoS Class Identifier, QCI)=1;

Step S15, after the 4G voice is over, go to the 5G cell through FastReturn (blind redirection).

EPS Fallback based on measurement redirection:

The EPS fallback based on measurement redirection is basically similar to the EPS fallback based on handover in terms of process, but there are differences in the fallback method; the EPS fallback based on redirection is through Radio Resource Control (RRC) after the B1 measurement of NR The target frequency carried in the release (Release) will fall back and forth to the LTE network.

The main steps are as follows:

Step S21, gNB sends B1 measurement to UE;

Step S22, the UE reports the B1 measurement, which includes the PCI of the target cell, the measured cell level, and the measured measid;

Step S23, the gNB that satisfies the B1 threshold is redirected to the LTE network through the RRC Release message, and the message must include the frequency point of the target cell.

EPS Fallback based on blind redirection:

The biggest difference between EPS Fallback based on blind redirection and handover-based and measurement-based redirection is that it does not need to perform any measurement, and it is directly redirected to the LTE network as long as the voice service is performed.

2. Event B1 (Inter RAT neighbor becomes better than threshold)

The event B1 can be used for inter-radio access technology (Radio Access Technology, RAT) handover process that does not depend on the coverage of the serving cell. For example, in the load balancing feature, it is decided to move UE away from NR due to load conditions rather than radio conditions. In this case, the UE only needs to verify that the target cell in other RAT (e.g. LTE) is better than a certain signal level threshold and can provide sufficient coverage.

Trigger condition: Mn+Ofn+Ocn–Hys>Thresh;

Cancellation condition: Mn+Ofn+Ocn+Hys<Thresh.

The measurement, indication, and information acquisition methods, devices, terminals, and network-side equipment provided by the embodiments of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

As shown in Figure 2, this embodiment of the present application provides a method for measuring network fallback, including:

Step 201, the terminal acquires measurement configuration information of the first access network when it is in an idle state or an inactive state;

It should be noted that the first access network refers to an access network different from the network currently accessed by the terminal, because this application is mainly aimed at network rollback, that is, the first access network The network capability is lower than that of the network currently accessed by the terminal. For example, if the terminal is currently connected to a 5G network, the first access network is a 4G network, that is, the Evolved Universal Mobile Telecommunications System radio access network (Evolved Universal Mobile Telecommunications System , E-UMTS).

It should be noted that the measurement configuration information refers to measurement configuration information for the terminal to perform early measurement, and the early measurement refers to that the terminal performs measurement before entering the connected state.

Step 202, when the first condition is met, the terminal performs measurement according to the measurement configuration information;

It should be noted that the first condition includes at least one of the following:

A11. A terminal in an idle state or an inactive state receives the first paging;

It should be noted that the first paging is used to indicate that network fallback is required, or the paging reason included in the first paging is the first reason;

Wherein, the first reason is to execute the first service or to perform network fallback;

A12. The RRC establishment reason of the terminal is the second reason;

It should be noted that the second reason indicates that network fallback needs to be performed or that the terminal requests to execute the first service.

It should also be noted that the terminal that this embodiment of the present application mainly targets should meet the following requirements: the network where the terminal currently resides does not support the first service (that is, the network where the terminal currently resides does not support the 5G NR function), and the terminal Support the first fallback (that is, the terminal receives indication information from the Access and Mobility Management Function (AMF) indicating that the terminal can perform voice services or emergency services on the network for fallback, and the terminal having a first fallback capability), the first fallback is network fallback or access network fallback, and the terminal supporting the first fallback includes that the terminal has the first fallback capability and/or the terminal receives target indication information Instruct the terminal to fall back when executing the first service. It should be noted that the target indication information is certain indication information that instructs the terminal to fall back when executing the first service, and the first service includes at least one of an emergency service and a voice service. item.

It should be noted that, in the embodiment of the present application, the measurement configuration information of the first access network is acquired in the idle state or inactive state, and when the first paging is received or RRC establishment is initiated due to the second reason , to perform measurement, so that the measurement can be performed before the RRC connection, and the delay of EPS Fallback can be reduced.

It should be further noted that the measurement configuration information includes the following item:

A21. Frequency point information;

It should be noted that the frequency point information includes: identification information of carrier frequencies of the N first access networks and a measurement bandwidth corresponding to each carrier frequency, where N is an integer greater than or equal to 1.

Optionally, the frequency point information also includes at least one of the following:

A211, the measurement cell information corresponding to each carrier frequency;

It should be noted that the measurement cell information may be a cell list composed of identifiers of a plurality of measurement cells.

A212, the reporting type corresponding to the measurement result;

It should be noted that the reporting type may include but not limited to: at least one of RSRP, Reference Signal Receiving Quality (RSRQ) and Signal to Interference plus Noise Ratio (SINR).

A213, filter coefficients for layer three (layer 3, L3);

It should be noted that the function of the filter coefficient is to obtain the measurement result.

A214, blacklist community;

It should be noted that the blacklist cell is mainly used to indicate the cell that cannot be measured, that is to say, when the frequency point information includes a blacklist cell, if the blacklist cell includes cell A, the terminal cannot perform measurement. Cell A is measured by using the frequency point information.

A22, frequency point information and measurement interval;

It should be noted that when some terminals perform measurements in the connected state, they do not need to perform measurements based on the measurement interval, while some terminals must use the measurement interval to perform measurements. In this case, when the terminal is in the idle state or inactive When the state cannot guarantee the completion of the measurement, the network side device must configure the frequency point information and the measurement interval for the terminal at the same time.

It should be noted that the optional implementation of step 201 includes at least one of the following:

A31. The terminal receives a broadcast message, and the broadcast message includes measurement configuration information of the first access network;

That is to say, in this case, the terminal in the idle state or the inactive state obtains the measurement configuration information of the first access network by receiving the broadcast message sent by the network side device.

A32. The terminal receives an RRC dedicated message;

It should be noted that the RRC dedicated message includes measurement configuration information of the first access network.

Optionally, the RRC dedicated message may be, for example, an RRC release message, that is, the terminal obtained the measurement configuration information of the first access network when the last connection was released, and the RRC dedicated message may also be an RRC reconfiguration message. message, that is to say, the terminal acquired the measurement configuration information of the first access network during the last connection.

It should be noted that the above shows that the terminal needs to perform measurements before entering the connected state, but the terminal may have completed the measurement or may not have completed the measurement when entering the connection state. The following is based on the implementation of the terminal completed measurement and the terminal not completed measurement. described as follows.

Case 1: The terminal has completed the measurement when it enters the connected state

It should be noted that in this case, the time for the terminal to enter the connected state is postponed (or delayed), that is, the process of entering the connected state is executed only after the terminal completes the measurement of the frequency point of the first access network. Specifically, after the step 202, another embodiment of the present application further includes:

After the measurement is completed, the terminal establishes an RRC connection;

During the RRC establishment process or after the RRC establishment is completed, the terminal sends the first indication information to the network side device.

It should be noted that, when the terminal has completed the measurement of the first access network, it can inform the network side device that it can provide the measurement result of the first access network. Optionally, the first indication information is used to report to the network The side device indicates that the terminal has completed the measurement of the first access network or indicates that the terminal has a measurement result of the first access network.

The terminal may send the first indication information to the network side device during the RRC establishment process, or may send the first indication information to the network side device in the connected state after the connection establishment is completed; optionally, the terminal sends the first indication information to the network side device The network side device sends first indication information, including:

The terminal sends a first message to the network side device, where the first message carries first indication information;

Wherein, the first message includes: at least one of an RRC establishment request message, an RRC establishment complete message, an RRC recovery request message, an RRC recovery complete message, and an RRC reconfiguration complete message.

It should be noted that the RRC Establishment Request message, RRC Establishment Complete message, RRC Recovery Request message and RRC Recovery Complete message are messages transmitted during the connection establishment process, while the RRC Reconfiguration Complete message is transmitted in the connected state.

It should be further noted that after this, the terminal can send the measurement result to the network side device to assist the network side device in the configuration of handover or redirection. Specifically, the terminal sends a third message to the network side device, so The third message carries the measurement result corresponding to the measurement configuration information;

Wherein, the third message includes at least one of the following:

B11, RRC recovery completion message;

B12, RRC reconfiguration complete message;

B13, uplink (Uplink, UL) information transfer message (UL Information Transfer IRAT);

B14, terminal information response message (UE Information Response);

B15, uplink dedicated control channel (Dedicated Control Channel, DCCH) information (UL-DCCH-Message);

It should be noted that each item in B12-B15 is a message sent by the terminal in the connected state.

Optionally, the measurement results include at least one of the following:

B21, the measurement result of the cell contained in each carrier frequency indicated by the terminal in the measurement configuration information;

That is to say, at this time, there is one measurement result for each cell included in each carrier frequency.

B22. The measurement results of each carrier frequency obtained by the terminal according to the measurement results of the cells contained in each carrier frequency in the measurement configuration information;

That is to say, there is only one measurement result for each carrier frequency at this time.

The communication between the terminal and the base station is taken as an example below to describe this situation in detail as follows.

Step S11, cells supporting EPS Fallback carry the measurement configuration information of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) in the broadcast message , including multiple frequency point information, each frequency point information must include:

E-UTRAN frequency point (carrier frequency) and the maximum measurement bandwidth corresponding to each frequency point;

Optionally, each frequency point information may also include: a list of measurement cells corresponding to each frequency point configuration, a report type (for example, RSRP, RSRQ or SINR, etc.) corresponding to the measurement result, and a filter coefficient for layer 3, etc.

Step S12, the UE receives the broadcast message, and reads the E-UTRAN measurement configuration information from the broadcast message.

Step S13, the UE supporting EPS Fallback listens to its own paging, and the paging message/paging physical downlink control channel (Physical Downlink Control Channel, PDCCH) carries a paging reason that needs to perform voice (voice) service, or The paging message indicates that EPS fallback needs to be performed, and the UE performs E-UTRAN frequency point measurement;

The measurement here refers to that the UE performs measurement on the corresponding E-UTRAN frequency point according to the measurement configuration information in step S11.

In step S14, after the UE completes the measurement, it executes the RRC connection establishment/RRC connection recovery process.

That is to say, the terminal does not perform the RRC establishment process before completing the measurement.

Optionally, the UE sends the first indication information to the base station, which is used to indicate that the UE has completed the measurement of the E-UTRAN frequency point related to EPS Fallback or indicates that the UE has the measurement result of the E-UTRAN frequency point related to EPS Fallback.

The first indication information is carried in an RRC establishment request message, an RRC establishment complete message, an RRC recovery request message or an RRC recovery complete message.

In step S15, the UE sends a measurement report to the base station, and the measurement report includes the measurement results of the frequency points configured in the broadcast message of the E-UTRAN required by the EPS Fallback.

Optionally, the base station may carry request information for requesting measurement results of E-UTRAN frequency points in an idle (idle) state in an RRC resume (RRC Resume) message.

In step S16, the base station selects a suitable E-UTRAN frequency point for handover or redirection configuration according to the measurement report of the UE.

Case 2: The terminal does not complete the measurement when it enters the connected state

It should be noted that, in this case, the terminal has not completed the measurement in the idle state or the inactive state, and the terminal needs to continue to perform the measurement after entering the connected state. Optionally, after the step 202, another aspect of the present application An embodiment also includes:

It should be noted that, usually, when the terminal has not completed the measurement, it can inform the network side device of this situation before continuing the measurement. Optionally, the terminal uses the measurement configuration information to perform the measurement in the connected state Previously, also included:

The terminal sends second indication information to the network side device, where the second indication information is used to indicate that the terminal has measurement configuration information of the first access network or that the terminal performs measurement using the measurement interval in the measurement configuration information.

The terminal may send the second indication information to the network side device during the RRC establishment process, or may send the second indication information to the network side device in the connected state after the connection establishment is completed; optionally, the terminal sends the second indication information to the network side device The network side device sends second indication information, including:

The terminal sends a second message to the network side device, where the second message carries second indication information;

Wherein, the second message includes: at least one of an RRC establishment request message, an RRC establishment complete message, an RRC recovery request message, an RRC recovery complete message, and an RRC reconfiguration complete message.

That is to say, when the terminal uses the RRC establishment request message, the RRC establishment complete message, the RRC recovery request message, and the RRC recovery complete message to send the second indication information, it means that the terminal implements the sending of the second indication information during the RRC establishment process. When the terminal uses the RRC reconfiguration complete message to send the second indication information, it means that the terminal realizes sending the second indication information in the connected state.

It should be further noted that, after this, the terminal can send the measurement result to the network side device to assist the network side device in handover or redirection. Specifically, after the terminal measurement is completed and the measurement result is obtained, the terminal sends a third sending a message to the network side device, the third message carrying the measurement result corresponding to the measurement configuration information;

Wherein, the third message includes at least one of the following:

RRC recovery complete message;

Optionally, each frequency point information may also include: a measurement cell list corresponding to each frequency point configuration, a reporting type corresponding to the measurement result (for example, RSRP, RSRQ or SINR, etc.), filter coefficients for layer 3, and the like.

Step S22, the UE receives the broadcast message, and reads the measurement configuration information of the E-UTRAN from the broadcast message;

Step S23, when the UE supporting EPS Fallback needs to initiate a voice service and needs to establish an RRC connection, the UE performs E-UTRAN frequency point measurement;

Step S24, the UE executes the RRC connection establishment/RRC recovery process, and indicates to the base station that the UE has the E-UTRAN measurement configuration information of the broadcast message configuration;

Step S25, the UE performs the measurement using the Measurement Gap in the connected state.

Optionally, before step S25, the UE may send second indication information to the network side device to instruct it to use the measurement interval for measurement; the second indication information is included in the RRC establishment request message, RRC establishment complete message, RRC recovery Carried in the request message or the RRC recovery complete message.
