摘要： A method performed in a mobility management node includes the mobility management node receiving a first Packet Data Network (PDN) activation request from a wireless local area network (WLAN) access gateway, the first PDN activation request specifying an access point name (APN) and a tunnel endpoint identifier (TEID) parameter for identifying the WLAN access gateway, the WLAN access gateway connected to a user equipment (UE). The method further includes in response to receiving the PDN activation request, the mobility management node (i) selecting a Packet Data Network Gateway (PGW) based on the specified APN, (ii) generating a second PDN activation session request that includes the TEID parameter for identifying the WLAN access gateway, (iii) selecting a serving gateway (SGW), and (iv) forwarding the second PDN activation request to the selected SGW.

摘要： In one aspect, a method for a packet gateway node (PGW) is disclosed. The PGW being adapted for (a) communicating with at least a serving gateway node, SGW, (b) receiving and forwarding downlink data packets to a user entity, UE, and (c) communicating with a mobility management entity, MME. In one embodiment, the method comprises: the PGW, when receiving a downlink user plane data packet destined for the UE on a Packet Data Network, PDN, connection associated with a restarted SGW, determining if the PDN connection has not yet been relocated to a new SGW, and, if so, selecting at least one SGW from a set of SGWs including the restarted SGW or another SGW and transmitting a control plane signal to at least one of the selected SGWs, the control plane signal identifying at least the UE.

摘要： A method for assigning a cellular network identity. The method comprises receiving (222), in a user equipment capable to attach to a cellular network and a wireless local area network, a unique representation of a user equipment context of the user equipment and in what cellular network node the user equipment is or is going to be attached, from a network node. The unique representation is labelled (224) as a cellular network identity and cellular network identity is stored (226) a pseudonym identity and/or a fast re-authentication identity in a memory in the user equipment.
