Abstract: Disclosed is a method for transmitting a buffer status report (BSR) by a terminal performing a handover procedure from a first network element to a second network element in a mobile communication system, including identifying a data packet available for transmitting and packet data convergence protocol (PDCP) control information, generating a BSR based on the data packet and the PDCP control information, the PDCP control information including header compression control information and a PDCP status report indicating which PDCP data is missing, and transmitting the generated BSR to the second network element, wherein the PDCP status report is transmitted to the second network element based on the BSR as a first PDCP PDU during the handover procedure performed by the terminal.

Abstract: Methods and apparatus for supporting emergency communications are provided. A method for a Radio Access Network (RAN) serving at least one Core Network (CN) to support emergency communications of a User Equipment (UE) includes determining whether at least one CN in a shared network environment supports emergency communications, if it is determined that the at least one CN in the shared network environment supports emergency communications, transmitting an emergency call support indication to the UE indicating that emergency communications are supported, receiving a request for emergency communications from the UE, and routing the request for emergency communications to another CN that supports emergency communications in the shared network environment, if a given CN does not support emergency communications.
