The second S-CSCF node can then send a request to the HSS for an identifier of an AS associated with the UE. Upon receipt of the AS identifier (e.g., an active AS name AVP) from the HSS, the second S-CSCF node can send the SIP request to the AS in order to restore the communication session for the UE.

Abstract: The application relates to the removal of one of the links in multi-flow HSPA but the proposed method is also applicable to normal HSDPA operation during handover. In particular the application aims at minimizing the negative impact of a removed radio link, i.e. drop of packets and/or delays. According to the proposed method, in which the radio link to be removed is via a first Node B NB1 (RL Removal Req), the NB1 ends the pending data transmission and informs the controlling RNC about the data which was not transmitted, in particular in the form of the lowest sequence number in its buffer. Subsequently, the RNC decides, based on this sequence number, which data packets need to be retransmitted on a second radio link via a second node B NB2, and instructs NB2 accordingly (Data Forwarding).
