Abstract: Techniques for correlating and load balancing IMS traffic in a visibility network are provided. According to one set of embodiments, a packet broker of the visibility network can receive IMS traffic replicated from an IMS core network and identify control/data packets in the IMS traffic that are part of the same IMS session based on FROM and TO user identities included in the packets. The packet broker can then generate a unique session identifier for the IMS session and add the generated session identifier to the packets. In certain embodiments, the packet broker can further provide the generated session identifier as input to a load balancing algorithm or rule set. The load balancing algorithm or rule set can output an egress port of the packet broker through which the control/data packets should be forwarded based on the session identifier.

Abstract: A method and a system which enables a User Equipment (UE) in a Universal Mobile Telecommunications System (UTMS) to achieve fast dormancy in least possible time are provided. The method reduces the signalling burden on UE and Universal Terrestrial Radio Access Network (UTRAN) by eliminating the need of SCRI procedure by introducing cause value as ‘end of user data’ in Cell update cause Information element which can be used in cell update message in a Paging Channel (Cell_PCH) state and a UTRAN registration area (URA_PCH) states indicated to the network. The method reduces the time and signalling to transition the UE to an idle mode time and the method is energy efficient.

Abstract: A method and system to receive the secondary notification messages when an ETWS primary notification message is received in connected mode of UE are provided. The method includes the way to receive the secondary notification information in UE. The secondary notification information comprises necessary associated information of the ETWS like government aid, help centers, health centers, and refugee camps and so on to help the user in many ways to combat the situation. The method discloses different ways of transition to idle mode to receive the secondary notification message according to configuration defined by the user within the UE.
