Apparatuses, systems, and methods for application awareness interworking between cellular systems. A wireless device may be configured to initiate an application during an ongoing procedure serviced by a first operating according to a first radio access technology (RAT), receive, from a first cellular system, an indication to switch to a second cellular system operating according to a second RAT, and delay the switch to the second cellular system until completion of the ongoing procedure. A network function may be configured to detect initiation of an application during an ongoing procedure serviced by a cellular system operating according to a first RAT, the application having associated application preferences, determine that the associated application preferences indicate a switch to a second cellular system operating according to a second RAT, and delay the switch to the second cellular system until completion of the ongoing procedure.

Embodiments of this application provide a communication method and a device. The communication method and the device may be used in the field of a communication technology that supports a reduced capability terminal device, for example, weak-capability UE or MTC UE. The method includes: A first network device determines that a type of a first terminal device is a first type. The first network device sends a handover request message. The handover request message includes first indication information. The first indication information includes identifier information of the first type. The first network device receives a handover acknowledgment message or a handover preparation failure message.

Certain aspects of the present disclosure provide techniques for handling slice information for a roaming user equipment (UE). In some cases, the UE may send, to a network entity, a request with an information element (IE) indicating one or more protocol data unit (PDU) sessions to be transferred from a source network to a target network. After receiving, from the network entity, a response with an IE identifying one or more of the PDU sessions allowed to be transferred to the target network and indicating slice information applicable in the target network for the one or more PDU sessions allowed to be transferred, the UE may update slice information for each of the PDU sessions allowed to be transferred based on the IE in the response.

A handover method and a communication apparatus are provided. The method includes: After sending a handover command to a terminal device, a source network device sends, to a target network device, at least one data packet that is not successfully received by the terminal device, so that after the terminal device accesses the target network device, the target network device sends, to the terminal device, the at least one data packet received from the source network device. Because the data packet forwarded by the source network device to the target network device includes a data packet on which the source network device has performed PDCP processing and for which no acknowledgment response from the terminal device is preceived, a data loss of the terminal device in an inter-system handover process can be effectively avoided.

A method and an apparatus for managing a mobility pattern of a terminal are disclosed, to flexibly configure and manage a mobility pattern of a terminal based on an actual application scenario of the terminal, and optimize network performance. The method is: obtaining, by a control plane function (CPF) entity, mobility pattern related information of a terminal; determining, by the CPF entity, a first mobility pattern of the terminal based on the mobility pattern related information of the terminal; and sending, by the CPF entity, the determined first mobility pattern to a radio access network (RAN) node, where the first mobility pattern is used by the RAN node to determine a second mobility pattern of the terminal.

A method performed by user equipment (UE) includes receiving a request to access a service unavailable through a first network cell associated with the UE, and receiving a message from an access device associated with the first network cell, wherein the message identifies a plurality of second network cells providing the service.

A user equipment receives multiple conditional reconfigurations associated with respective conditions. The user equipment is to execute a conditional configuration upon fulfillment of an associated condition. The user equipment accordingly executes one of the multiple conditional configurations upon fulfillment of an associated condition. The user equipment transmits, to a target radio network node, an indication that indicates which one of the multiple conditional reconfigurations the user equipment executed.

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. Accordingly, the embodiments herein provide a method for Management data analytic service (MDAS) server (100) assisted handover optimization in a wireless network (1000). The method includes periodically collecting data from a plurality of target gNBs in the wireless network (1000), and generating an analytical report for each target gNB (300) of the plurality of target gNBs based on the collected data. Further, the method includes receiving a request for the analytical report of the at least one target gNB (300) for handover from a source gNB (200), sending the analytical report to the source gNB (200). Further, the includes performing at least one corrective action suggested by the analytical report to optimize at least one target gNB (300) for handover.

Provided are a communication mode switching method, and an apparatus and a device. The method includes sending a Packet Data Convergence Protocol (PDCP) data transmission status of user equipment in a first communication mode to a second network device, wherein the second network device is configured to use a second communication mode to deliver a service to the user equipment according to the PDCP data transmission status.

A method of processing state information relating to user equipment in a communications system comprising a radio access network, the method comprising: maintaining current state information relating to the user equipment; and on the basis of a change of connection of the user equipment from a first cell to a second cell: transmitting a current value associated with a given state information part to the target radio access node in response to detecting at least one of one or more predetermined triggers that indicate that the target radio access node may not have received the current value from the source radio access node; or relying on the target radio access node having received the current value from the source radio access node if said at least one of said one or more predetermined triggers is not detected.
