A type of network traffic associated with a packet received from a remote node of an access network is determined. A first interface logic routes the packet to a radio network controller (RNC) if the packet is received from an Internet protocol-basestation (IP-BTS) access network and destined to a packet core network. The RNC forwards the packet to a component of the packet core network. A second interface logic routes the packet to the component of the packet core network, including aggregating other packets of the same type received from other remote nodes, if the packet is received from a femto cell and destined to the packet core network. A breakout logic routes the packet to a destination of the Internet directly to enable the packet to reach the Internet without having to route the packet to the component of the packet core network, if the packet is destined to the Internet.

The invention provides a method and a system for realizing accessing through a wireless local area network (WLAN) access network. The method comprises the following steps that: user equipment (UE) accesses an evolved packet core network (EPC) and interacts with access network discovery and selection function (ANDSF) to acquire access network information of a WLAN; and the UE is connected with the wireless local area network access network (WLANAN) and accesses the core network by using the acquired access network information of the WLAN. Because the UE previously accesses the EPC and interacts with the ANDSF to acquire the access network information of the WLAN, namely the UE knows the wireless core network to which the current WLANAN is connected or can be accessed. Thus, the wireless core network which subsequently participates in access authentication is the wireless core network to which the current WLANAN is connected or can be accessed, successful accessing of the UE is ensured, and the load of the UE and the network is reduced, so that the resource is saved and the user experience is enhanced.

A method and apparatus provide network-based flow control for mobile station having data connections to the network. In an exemplary embodiment, a Packet Control Function (PCF) in a Radio Access Network (RAN) requests that a Packet Data Serving Node (PDSN) in a Packet Core Network (PCN) turn flow control on and off as needed for mobile station data connections. That is, if the PCF receives data from the PDSN for delivery to a mobile station that the PCF determines to be unavailable, the PCF requests that data transfers from the PDSN be suspended for that mobile station. Such suspension avoids needless continued transfer of undeliverable data to the PCF. The PCF monitors or otherwise determines whether a flow-controlled mobile station has become available again and, if so, notifies the PDSN so that it can lift the suspension and resume data transfers as needed.
