Abstract
Various solutions for radio access technology (RAT) redirection in mobile communications are described. The user equipment (UE) may determine that a requested service is not supported by a current RAT of the UE. Also, the UE may transmit a service request to a network node. Specifically, the service request comprises a service type indicating a service request for other RAT. Further, the UE may receive an accept message from the network node for connection release with redirection to a target RAT. Accordingly, the seamless service continuity across heterogeneous RATs can be ensured.
Claims20
A method, comprising:
- determining, by a processor of an apparatus, that a requested service is not supported by a current radio access technology (RAT) of the apparatus;
- transmitting, by the processor, a service request to a network node, wherein the service request comprises a service type indicating a service request for other RAT;
- and
- receiving, by the processor, an accept message from the network node for connection release with redirection to a target RAT.
An apparatus, comprising:
- a transceiver which, during operation, communicates wirelessly;
- and
- a processor communicatively coupled to the transceiver such that, during operation, the processor performs operations comprising:
- determining that a requested service is not supported by a current radio access technology (RAT) of the apparatus;
- transmitting, via the transceiver, a service request to a network node, wherein the service request comprises a service type indicating a service request for other RAT;
- and
- receiving, via the transceiver, an accept message from the network node for connection release with redirection to a target RAT.
A method, comprising:
- receiving, by the processor of a network node, a service request from a user equipment (UE), wherein the service request comprises a service type indicating a service request for other radio access technology (RAT);
- and
- transmitting, by the processor, an accept message to the UE for releasing a connection with a current RAT of the UE and redirection to a target RAT.
