摘要： A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a service network. The controller transitions the UE from a Radio Resource Control (RRC) idle state to an RRC connected state, and after transitioning the UE from the RRC idle state to the RRC connected state, sends an initial Non-Access Stratum (NAS) message comprising a limited set of Information Elements (IEs) in cleartext, which are required to establish security between the UE and the service network, and a container IE carrying an initial NAS message Protocol Data Unit (PDU) ciphered with NAS security context to the service network via the wireless transceiver.

摘要： A method of registering to slices with mapped S-NSSAI alone in a 5GS is described. The method can include, upon a UE entering a VPLMN, the UE having a first PDN connection or a first PDU session that is to be transferred to the VPLMN and associated with a first HPLMN S-NSSAI, determining whether the UE has a first VPLMN S-NSSAI applicable in the VPLMN corresponding to the first HPLMN S-NSSAI. If not, a registration request message can be transmitted to the VPLMN. The registration request message can include the first HPLMN S-NSSAI as a first mapped S-NSSAI for indicating a slice of the VPLMN to which the UE intends to register.

摘要： A method of supporting reception of standalone SERVICE ACCEPT message is proposed. In one embodiment, a new timer is started when the UE determines successful completion of the service request procedure and has not received SERVICE ACCEPT during the procedure. In an alternative embodiment, an existing timer T3417 or T3417ext can be used to define the allowed time window for the reception of SERVICE ACCEPT. While the timer is running, the UE can treat the SERVICE ACCEPT message as successfully received and the message does not cause protocol error.

摘要： Various examples pertaining to improvement for incorrect key set identifier (KSI) handling in mobile communications are described. An apparatus (e.g., user equipment) receives from a wireless network an authentication challenge after the processor having completed an authentication and key agreement (AKA) procedure with the wireless network. The apparatus detects an error in the authentication challenge and handles the error in the authentication challenge. For example, the apparatus can reject the authentication challenge responsive to detecting the error. Alternatively, the apparatus can accept the authentication challenge.
