For ease of understanding, the following describes some of the content involved in the embodiments of this application:

1. EPS Fallback based on switching.

When a terminal with EPS Fallback capability initiates a voice service requirement, the NR issues the B1 event measurement configuration of LTE. When the terminal meets the B1 threshold and reports, the NR side initiates a handover command to the LTE network, and the terminal switches to the LTE network for voice services (voice ).

The main steps are as follows:

1. The gNB sends the B1 event measurement configuration to the UE, carrying the Evolved Universal Terrestrial Radio Access Network (E-UTRA) to be measured in the measurement configuration. ) carrier frequency (frequency point) and B1 threshold.

2. The UE reports the measurement results to the gNB, including the B1 level of the LTE cell, the PCI of the cell, and the measurement identifier (measid).

3. The gNB sends a handover command to the UE, carrying the frequency point of the target cell and the physical cell identifier (Physical Cell Identifier, PCI).

4. Establish a dedicated bearer for the voice service whose Quality of Service (QoS) class indication (QoS Class Identifie, QCI) is equal to 1.

5. After the 4G voice is over, return to the 5G cell through redirection.

2. EPS Fallback based on measurement redirection.

The EPS fallback based on measurement redirection is basically similar to the EPS fallback based on handover, indicating that there is a difference in the fallback method; the EPS fallback based on redirection is received after the UE sends the NR measurement report containing the B1 measurement event to the network. The target frequency point carried in the radio resource control release (Radio Resource Control Release, RRCRelease) falls back and forth to the LTE network.

The specific process is as follows:

1. The UE receives the B1 event measurement configuration issued by the gNB;

2. The UE reports the measurement report of the B1 measurement event, which includes the PCI of the target cell, the measured cell level, and the measured measid;

3. The UE receives the RRC Release message sent by the gNB, which contains the target frequency point, and the UE performs redirection to the LTE network.

3. EPS Fallback based on blind redirection

The biggest difference between blind redirection-based EPS Fallback and measurement-based redirection is that before the UE is redirected to the LTE network, the UE does not necessarily send a measurement report, or the reported measurement report does not contain the measurement results of the target frequency.

4. Event B1, that is, the Inter RAT neighbor becomes better than the threshold (Inter RAT neighbor becomes better than threshold).

Measurement event B1 can be used for inter-RAT handover procedures that do 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.

The following describes in detail the advance redirection processing method provided by the embodiment of the present application through some embodiments and application scenarios with reference to the accompanying drawings.
