Aspects of the subject disclosure may include, for example, detecting a transit speed of a device, resulting in a detected transit speed; responsive to the detected transit speed satisfying a first threshold, including information in a message related to a handover request between a first access point of a network and a second access point of the network, the information being indicative of an amount of time that the device has been in a Discontinuous Reception (DRX) mode; and sending, to the first access point with which the device communicates and is transitioning away from, the message including the information that is indicative of the amount of time that the device has been in the DRX mode. Other embodiments are disclosed.

A method, performed by a terminal in a wireless communication system, includes: transmitting, to a first cell, capability information of the terminal including information on whether the terminal supports plurality of cell reselection priorities (CRPs); receiving, from the first EUTRAN cell, a radio resource control (RRC) Connection Release message including an alternativeCRPindication parameter indicating to apply CRP broadcast in system information, based on the capability information of the terminal; transitioning to an RRC idle mode or an RRC inactive mode based on the RRC Connection Release message, and camping on a second cell; receiving, from the second cell, system information; and determining, based on the system information, whether to apply a first CRP for an inter-RAT frequency or a second CRP for at least one EUTRAN frequency.

Re-connecting to a first radio access network (RAN) of a first radio access technology (RAT) may include initially connecting to the first RAN. A connection associated with a voice call may then be connected that includes connecting to a RAN of a second RAT. In response to the voice call connecting to the second RAN, information for both a frequency and a cell associated with connecting to the first RAN may be stored. An end to the voice call may be identified. In response to determining that the voice call has ended, a timer may be generated at the UE that comprises a specified time period and the timer and the information stored for both the frequency and the cell associated with connecting to the first RAN may be utilized to re-connect to the first RAN.

The present invention provides a method and an apparatus for leaving a network, and a terminal. The method includes: sending a leaving message to a network side, and starting a leaving wait timer; and performing a leaving network operation in a first case, where the first case includes any one of the following: the leaving wait timer expires; and a target message is received before the leaving wait timer expires.

A method and an apparatus for allocating processing resources may be used in a wireless communication network. The method includes: configuring by a base station, a first sidelink resource pool and a second sidelink resource pool. The first sidelink resource pool is a resource pool of sidelinks that can be used by a user equipment (UE) after entering an idle state or an inactive state, and the second sidelink resource pool being a resource pool of sidelinks that can be used by the UE in the idle state or the inactive state after the first sidelink resource pool has been released. The method further includes: sending by the base station, information of the first sidelink resource pool and information of the second sidelink resource pool to the UE.

A method for handling a collision of a UE-requested MA PDU session release procedure and a network-requested MA PDU session release procedure is proposed. If the Access type IE is included in the PDU SESSION RELEASE COMMAND message, and the PDU session is an MA PDU session and having user-plane resources established on the access different from the access indicated in the Access type IE in the PDU SESSION RELEASE COMMAND message, then the UE proceeds with both the UE-requested PDU session release procedure and network-requested PDU session release procedure. Otherwise, the UE aborts the UE-requested PDU session release procedure and stops the timer T3582 and proceeds with the network-requested PDU session release procedure.
