Abstract
Accordingly, embodiments disclosed herein provide a method for managing inter network switching by a User Equipment (UE) in a wireless communication system. The method includes determining that the UE is in data communication with a first network, determining that a signaling packet data network (PDN) is established for transmitting a Link Switch Message (LSM) for the inter network switching during the data communication with the first network, ignoring to perform a search for a second network until the signaling PDN is established for the first network and establishing the signaling PDN for the first network. Further it provides the method for detecting the condition of retransmission of LSM and provides method to avoid data loss and signaling overhead during inter-network switching.
