Abstract: The present disclosure refers to methods and systems to reduce delays in VoWI-FI handover and packet switching registration. The method includes triggering a Router Solicitation Router Advertisement (RSRA) procedure to establish a Transmission Control Protocol/Internet Protocol (TCP/IP) interface based on a determination that the VoWi-Fi handover of a user equipment (UE) is to be performed, determining if a router advertisement (RA) is received within a first time interval, and obtaining a full Internet Protocol version 6 (IPv6) address previously used by the UE in response to determining that the RA is not received within the first time interval, the full IPv6 address being for establishing the TCP/IP interface with a network.

Abstract: An apparatus and method are provided for receiving information related to an instant message (IM) transmitted from another electronic device through a Short Message Service (SMS) network and transmitting information related to message reception through the SMS network. An electronic device includes a reception unit for receiving a first message through a first network, a generation unit for generating a second message including information related to reception of the first message, and a transmission unit for transmitting the second message through the first network. The first message includes information associated with an IM transmitted from the another electronic device through a second network.
