Abstract: Methods and systems for triggers of leaving procedure methods and systems for triggers of leaving procedure. The method includes receiving, by the UE, an RRC signaling connection release from a wireless communication network. The RRC signaling connection release indicates that the UE moves to an RRC inactive state. The UE is in a multi-user services identity module (MUSIM) mode. The method includes determining, by the UE, if there is an activity over 3GPP access due to another USIM. The method includes transmitting, by the UE, a non-access stratum (NAS) message including a service request message. The method includes triggering, by the wireless communication network, a release procedure to transfer the UE to an IDLE state in response to receiving the services request message in RRC Inactive state.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method of operating a user equipment (UE) operable to communicate with a telecommunication network, comprising the steps of: the UE sending to the telecommunication network a control plane service request (CPSR) message with cellular Internet of Things (CIoT) user data, associated with a protocol data unit (PDU) session; the UE receiving from the telecommunication network a SERVICE ACCEPT message, indicating that the PDU session is inactive in the network; and the UE verifying if the PDU session has an identity the same as an identity of the PDU session included in the CPSR message with CIoT user data and, if so then the UE determines that the CIoT user data was not successfully sent to the telecommunication network or to a final recipient.

Abstract: A method for supporting end-to-end (e2e) Quality of Service (QoS) for uplink (UL) communication between a User Equipment (UE) and a network via a relay node, the method performed by the relay node, are provided. The method includes receiving, from the network, a downlink (DL) packet for the UE, wherein the DL packet includes a value of a first indicator of a QoS flow on a first link between the relay node and the network, and creating or updating a QoS rule, wherein the QoS rule is derived based on the value of the first indicator, and optionally wherein the created or updated QoS rule corresponds to the UE or to a QoS flow on a second link with the UE.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method of controlling timer T3440 or T3540 in a User Equipment, UE, the timer being operable to guard a time during which the UE maintains a certain type of connection to a telecommunication network, wherein the timer has a default first time period in the absence of a first condition and a second condition being met, wherein if both the first condition and the second condition are met, then the first default time period is extended to a second time period.
