then the h e nb reports the address of this local gateway and access point names supported by this local gateway when there are multiple local gateways connected with the h e nb then the h e nb can select one of the local gateways randomly and report the address of this local gateway and the access point names supported by this local gateway or can report the addresses of all the local gateways connected therewith and the access point names supported by respective local gateways particularly the h e nb reports them by sending the address es of the local gateway s and the information of the access points supported by the local gateway s to the core network control node in a message the step 103 is to determine whether the requested access point allows a selected ip traffic offload connection to be established the core network control node determines whether the requested access point allows a selected ip traffic offload connection to be established after obtaining the connection request of the ue and if so then it proceeds to the step 104 otherwise it establishes a packet data network connection through a core network gateway the core network control node obtains subscription information from a home subscriber server hss and then obtains local configuration information and the core network control node can determine from the subscription information and the local configuration information whether the access point requested by the ue allows a selected ip traffic offload connection to be established and the access point requested by the ue allows the connection to be established only if both the subscription information and the local configuration information indicate that the access point allows to establish the.
