Abstract: A secondary base station method, secondary base station, master base station method, master base station and computer program products are disclosed. The secondary base station method comprises: upon it being determined that the secondary base station is to perform a protocol layer re-establishment, permitting continued transmission of data packets to user equipment over the secondary base station bearer. In this way, service interruption can be minimized since pending data packets may continue to be transmitted while the re-establishment takes, which minimizes service interruption and reduces the number of data packets which will need to be retransmitted.

Abstract: Various communication systems can benefit from signaling optimization. For example, communication systems including fourth generation (4G) and fifth generation (5G) networks may benefit from network signaling optimization for light connected mode. A method can include identifying, by a device, that a user equipment has left an area. The method can also include starting, by the device, a suspend procedure for the user equipment based on identifying that the user equipment has left the area.

Abstract: In an embodiment, there is provided a method for allowing the switching of an S1-U uplink SGW termination point of a bearer during, respectively after, offloading of said bearer from a eNB referred to as Master eNB MeNB, to a eNB referred to as Secondary eNB SeNB, in a dual connectivity operation, said method including: signaling to said SeNB, via said MeNB, during, respectively after, offloading of said bearer, addressing information of a new S1-U uplink SGW user plane termination point to be used for said bearer after said switching.

Abstract: The application relates to the problem that when an HeNB switches off (HeNB1-3) while connected via a proxy (PR) as mentioned by Release 11 of 3GPP TR 37.803 to a peer X2AP entity, the X2AP entity in the HeNB can not inform its peer (eNB1) that it is no longer reachable. The problem is solved in that when the proxy detects the disconnection of the SCTP connection (SCT-P1-3) between the HeNB and itself, it transmits an X2AP STOP message to the eNB (eNB1), whereby this message indicates the end of the SCTP connection (SCTP1-3) and identifies the HeNB.
