摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Embodiments herein provide a method implemented in a User Equipment (UE). The method includes receiving, from a Mobility Management Entity (MME), a bearer resource modification reject message with a cause value, in response to a bearer resource modification request message sent to the MME. Further, the method includes deactivating an Evolved Packet System (EPS) bearer context information.

摘要： The present disclosure relates to a system and a method for connection management. The method includes establishing, by a UE, a connection with a 5G cell. The established connection with the 5G cell is in a current tracking area of a 5G New Radio (NR). Further, the method includes determining, by the UE, one or more Long-Term Evolution (LTE) cells in the current tracking area or registration area that are not accessible to the UE (300). The one or more LTE cells are configured to operate on an LTE frequency. Furthermore, the method includes temporarily deprioritising or disabling, by the UE, a Stand Alone (SA) mode based on the determination of the one or more LTE cells in the current tracking area or the registration area that are not accessible to the UE.

摘要： A method for an optimal cell selection for a UE in a wireless network, may include receiving a plurality of KPIs associated with the UE, determining whether at least one KPI from the plurality of KPIs meets at least one KPI criteria; and performing, one of: prioritizing a sub6 cell over a mmWave cell and selecting the sub6cell cell or prioritizing a LTE cell over a sub6 cell and selecting the LTE cell or, prioritizing the LTE cell over the mmWave cell and selecting the LTE cell, and prioritizing the mmWave cell over the sub6 cell and selecting the mmWave cell in response to determining that the at least one KPI from the plurality of KPIs does not meets the at least one KPI criteria.

摘要： A method of managing evolved universal mobile telecommunication system terrestrial radio access network (E-UTRAN) capability of a user equipment (UE) is provided that includes switching from a first radio access technology (RAT) to a second RAT if the first RAT fails to provide circuit switched (CS) services to the UE, the first RAT and the second RAT being associated with a first public landline mobile network (PLMN). The UE establishes a CS call session with the second RAT. In the meanwhile, the UE receives a network handover command to move to a second PLMN. The UE may also perform a movement from the first PLMN to the second PLMN and connect with a third RAT associated with the second PLMN to continue the CS call session. The UE enables the E-UTRAN capability after moving to the second PLMN to connect with a fourth RAT available in the second PLMN.
