Abstract
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.
