  • Enhancement on voice call continuity during handover
    Patent number: 9521592
    Abstract: A handover of a user equipment (UE) between different radio access networks (RANs). For enhancing voice call continuity (VCC). One method comprises: receiving a request for registering in a first node for mobility management in the target RAN from the UE; if the mobility management for the UE fails to be transferred from a second node for mobility management in the source RAN to the first node, inquiring of a HLR/HSS about a third node for mobility management for the UE in the source RAN, wherein the second node is determined from the request for registering, and the third node is determined based on a correlation between the UE and the third node; and sending to the third node a request for transferring the mobility management for the UE from the third node to the first node.

  • REDUCING SIGNALING LOAD CAUSED BY CHANGES IN TERMINAL LOCATION
    Publication number: 20150148073
    Abstract: This disclosure is directed to a serving node (220) and a method in a serving node (220) for reducing signalling caused by changes of location of a radio terminal (230), which serving node is configured to be operatively comprised by a wireless communication system (200), and to operatively handle payload data for the radio terminal, and to operatively communicate with a gateway node (210) acting as an interface between the system and an external network (250).
