Abstract: A method for handling collision of signaling messages between a user equipment (UE) and a network entity is disclosed. The method includes transmitting a first signaling message comprising a first access type and a second signaling message comprising a second access type different from the first access type. The UE is registered on a network for the first access type and the second access type. The method also includes determining that the first access type and the second access type correspond to different access types. The method further includes processing the first signaling message and the second signaling message based on the determination by processing of the first signaling message and the second signaling message in parallel or re-triggering one or more of the first signaling message or the second signaling message.

Abstract: A method performed by a User Equipment (UE) for managing a failure in a registration for accessing a network slice, and the UE including processing circuitry configured to perform the method, are provided. The method includes sending a registration request message to a first wireless network while the UE is in a tracking area of a registration area, the registration request message including a Single Network Slice Selection Assistance Information (S-NSSAI) corresponding to the network slice, receiving a registration reject message from the first wireless network indicating that the network slice is unavailable, storing a Tracking Area Identifier (TAI) of the tracking area to a rejected list based on the TAI of the tracking area being included the registration reject message, and establishing a connection with a second wireless network in response to the receiving.

Abstract: A user equipment (UE) may ascertain an incapability of the network to process a pending uplink signal based on a registration acceptance message from the network. For instance, a registration acceptance message from the network, that may indicate the network is not capable of processing the pending uplink signal service. Accordingly, upon ascertaining the incapability of the network to process the pending uplink signal, the UE may release a connection (e.g., a N1 Non-Access Stratum (NAS) signaling connection) between the UE and the network, where the connection is based on camping of the UE at a cell corresponding to the radio access network (RAN) (e.g., the NG-RAN) of the network. Alternatively, the UE may initiate one of an implementation dependent timer and a release timer (e.g., a T3540 timer) to release the connection (e.g., to release the N1 NAS signaling connection).
