Abstract: A method for controlling, by a user equipment (UE), PDCP aggregation in a dual connectivity mode includes receiving a first Uplink (UL) data threshold value from a network; monitoring a throughput of a UL data of the UE and occurrence of at least one UL channel condition, wherein the at least one UL channel condition includes at least one of a network condition and a UE condition; determining whether to perform a calculation of a second UL data threshold value based on the occurrence of the at least one UL channel condition; calculating the second UL data threshold value based on a plurality of network parameters and a plurality of UE parameters, based on determining to perform the calculation of the second UL data threshold value; comparing an amount of the UL data with the second UL data threshold value; and controlling PCDP aggregation based on a result of the comparison.

Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system. A method for Network slice admission control for interworking with an Evolved Packet Core Network (EPC) in a wireless network by a Session Management Function-Packet Data Network Gateway (SMF-PGW-C) is provided. The method includes detecting that at least one UE transfers a Packet Data Network (PDN) connection or a Protocol Data Unit (PDU) session from a N1 mode to a S1 mode during an intersystem change. Further, the method includes determining that an EPC counting is not required for a network slice of the wireless network. Further, the method includes transmitting a message to a Network Slice Admission Control Function (NSACF) in the wireless network to update or reduce a number of User Equipments (UEs) per network slice and a number of PDU sessions per network slice.

Abstract: A method and system in the User Equipment (UE) for maintaining rejected network slice selection assistance information (NSSAI) for Single Network Slice Selection Assistance Information (S-NSSAI) not available due to maximum number of UEs reached per access type. The method comprises receiving a Non-Access Stratum (NAS) message including at least one of a registration accept, registration reject or CONFIGURATION UPDATE COMMAND message along with at least one of rejected Single Network Slice Selection Assistance Information (S-NSSAI(s)) information and a cause for the S-NSSAI not available due to maximum number of UEs reached from a network. Thereafter, the method includes determining by the UE an access type on which the rejected S-NSSAI(s) is applicable based on the received S-NSSAI(s) information and then maintaining a storage of the rejected NSSAI for the S-NSSAI not available due to the maximum number of the UEs reached per access type based on the determination.

Abstract: In an example embodiment, a method of optimizing service delivery performed by a UE operating in EN-DC mode is disclosed. The method comprises detecting that a network service is ongoing at the UE using a first radio access technology (RAT), based on an application request sent by the UE to a network, wherein the first RAT is one of long-term evolution (LTE) and NR. The method further comprises detecting, during the ongoing network service being availed using the first RAT, a frequency of one or more NR network procedures being performed by the UE to be greater than a first threshold frequency. The method further comprises modifying a measurement interval associated with an NR cell measurement procedure, in response to detecting the frequency of the NR network procedures to be greater than the first threshold frequency. Furthermore, the method comprises continuing the Network Service using the first RAT.
