The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. For example, the disclosure relates to a method for switching a data session for an application, implemented in a user equipment with dual SIM. The method includes: determining a User Equipment (UE) Route Selection Policy (URSP) rule for a primary Subscriber Identity Module (SIM) and a secondary SIM. The method includes detecting a trigger for switching the data session of the application to the secondary SIM based on determination of the URSP rule, wherein the trigger includes one of a matching traffic descriptor, a dedicated network slice, a Quality of Service (QoS) rule and a user preference. The method includes configuring the secondary SIM for the DDS based on the trigger; and switching the data session of the application to the secondary SIM for continuing the data session.

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.

In a wireless User Equipment (UE), a serving radio wirelessly exchanges data with a serving cell over a serving radio band. The wireless UE wirelessly receives serving signaling that indicates serving uplink interference for the serving radio band at the serving cell. A neighbor radio in the UE wirelessly receives neighbor signaling. UE circuitry determines serving signal strength and the serving uplink interference for the serving cell. The UE circuitry determines neighbor signal strength for the neighbor cell. The UE circuitry compares the serving uplink interference and the serving signal strength to the neighbor signal strength, and in response, generates a handover request for the neighbor cell. The serving radio wirelessly transfers the handover request to the serving cell, and in response, the neighbor radio wirelessly exchanges additional data with the neighbor cell over the neighbor radio band.

Systems, apparatuses, and methods are described for wireless communications. Random access procedures may include various types of procedures, such as 4-step or 2-step random access procedures. One or more indicators may be included in one or more messages for a handover to indicate a type of a random access procedure.

A network side device and a non-transitory computer readable storage medium are provided. The computer readable storage medium includes a computer program stored thereon, wherein when the computer program is executed by a processor, the processor implements following steps: receiving a message transmitted by a network side device; and acquiring, from the message, an inactive-state DRX parameter configured by the network side device for a terminal, wherein, receiving the message transmitted by the network side device includes: receiving, in a process of updating a RAN notification area, a Msg 4 transmitted by the network side device, in a case that the terminal is in an inactive state, wherein the inactive-state DRX parameter is carried in the Msg 4.

Example communication methods and apparatus are described. One example method includes sending a handover request message to a target base station, where the handover request message is used to instruct to hand over a first session of a terminal device from the source base station to the target base station. The handover request message includes first information. The first information includes information about at least one quality of service (QoS) flow in the first session. The first session is a session corresponding to the terminal device. The source base station receives a handover request response message from the target base station, where the handover request response message includes second information. The second information is used to indicate that the target base station accepts a first QoS flow in the first session, and the at least one QoS flow includes the first QoS flow.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and equipment for handover are provided. The method includes informing, by a source base station, a source core network whether a direct data forwarding path is available, determining, by the source core network, whether to use direct data forwarding or indirect data forwarding, informing, by the source core network, a target core network of information of direct data forwarding, indirect data forwarding or data forwarding being not possible, informing, by the target core network, a target base station of the information of direct data forwarding, indirect data forwarding or data forwarding being not possible, and allocating, by the target base station, tunnel information for data forwarding.
