Abstract: 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. A method of handling control plane data in a wireless network. The method comprises sending, by a user entity (UE), a non-access stratum (NAS) message along with an indication data to a mobility management (MM) core network entity. The MM core network entity processes the received NAS message and the indication data. The MM core network entity determines status of network congestion upon processing the processed NAS message. Sending, by the MM core network entity, a response to the UE based on at least one of the processed indication data and the determined network congestion.

Abstract: The embodiments herein achieve a method and a UE for enabling a transport layer optimization using a preemptive cross layer signaling. The method includes transmitting at least one information to the NR L2 receiver for the transport layer optimization for a data flow(s). The at least one information includes at least one of a configuration for requesting a buffer status of the NR L2 receiver, a policy to inspect data packets of the data flow(s), a configuration for enabling or disabling the transport layer optimization, a retransmission timeout (RTO) and a round trip time (RTT) of the data flow(s), an impending RTO value of the data flow(s) and a threshold value of a buffer size. Further, the method includes enabling the transport layer optimization based on the at least one information received from the NR L3 receiver to avoid receiving of duplicate data packets from a TCP sender.

Abstract: 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. Methods and systems for managing bearer configuration of user equipment (UE) with Evolved-Universal Terrestrial Radio Access Network-New Radio-Dual Connectivity (E-UTRAN-NR-DC) (EN-DC) capability. The UE detects connectivity issues in the UE itself and in interfaces connecting between a NR network with the UE, a LTE network, or an EPC that require disabling NR capability of the UE. The bearer configuration is determined and updated based on the detected connectivity issues. The UE signals the LTE network about the disabling of NR capability, requests enabling of data transfer through bearers of a MCG bearers associated with the LTE network in a current MCG RRC session, and prevents addition of SCG bearers associated with the NR network. The UE recovers data in the SCG bearers, lost due the issues in the NR network, through the MCG bearers. The UE can send a Tracking Area Update (TAU) to indicate the disabling of NR capability if the connectivity issues persist.

Abstract: According to various embodiments, an electronic device comprises a communication processor, an application processor operatively connected to the communication processor, and a memory, wherein the at least one memory may store instructions configured to, when executed, cause the application processor to identify a user identifier (UID) corresponding to at least one allowed application or at least one disallowed application when the electronic device enters a power saving state and to generate, on the basis of the user identifier, a first packet filter program which includes at least one condition for filtering a packet, and cause the communication processor to identify the first packet filter program generated from the application processor and to filter at least one packet associated with an application other than the at least one allowed application or at least one packet associated with the at least one disallowed application by using the first packet filter program, while the electronic device is in the power saving state. Various other embodiments are possible.
