Abstract
Apparatuses, methods, and systems are disclosed for providing fallback assistance information to a RAN node. One apparatus includes a transceiver that sends a service request, wherein the service request requires fallback to at least one of: a different radio access technology and a different core network (“CN”) and receives a connection release message, where the connection release message includes redirection information for the service fallback, the redirection information including the target CN. The apparatus includes a processor that selects a non-access stratum (“NAS”) procedure based on the target CN and connects to the target CN using the selected NAS procedure.
Claims20
A method comprising:
- sending, by a remote unit, a service request, wherein the service request requires fallback to at least one of:
- a different radio access technology (“RAT”) and a different core network (“CN”);
- receiving, at the remote unit, a connection release message, where the connection release message includes redirection information for the service fallback, the redirection information including a target CN;
- selecting a non-access stratum (“NAS”) procedure based on the target CN;
- and
- connecting to the target CN using the selected NAS procedure.
An apparatus comprising:
- a transceiver that:
- sends a service request, wherein the service request requires fallback to at least one of:
- a different radio access technology (“RAT”) and a different core network (“CN”);
- and
- receives a connection release message, where the connection release message includes redirection information for service fallback, the redirection information including a target CN;
- and
- a processor that:
- selects a non-access stratum (“NAS”) procedure based on the target CN;
- and
- connects to the target CN using the selected NAS procedure.
A method comprising:
- receiving, at a radio access network (“RAN”) node, a first message from a network function in a first core network, wherein the first message indicates service fallback of a remote unit connected to the RAN node and indicates a target core network (“CN”);
- determining service fallback parameters for the remote unit;
- and
- sending a connection release message to the remote unit, where the connection release message includes redirection information for service fallback, the redirection information including the target CN.
An apparatus comprising:
- a transceiver that receives a first message from a network function in a first core network, wherein the first message indicates service fallback of a remote unit connected to the apparatus and indicates a target core network (“CN”);
- and
- a processor that determines service fallback parameters for the remote unit,
- wherein the transceiver sends a connection release message to the remote unit, the connection release message including redirection information for the service fallback, the redirection information including the target CN.
