Abstract:
1. A method of operating a mobility management control node adapted to provide mobility management in a wireless network, the method comprising: retrieving from a directory a list of data functions correlated to corresponding gateway nodes, wherein each gateway node comprises at least one data function, wherein the directory is implemented in a node separate from the gateway nodes and separate from mobility management control nodes in the wireless network; receiving a message from a mobile station requesting activation of a connection, the mobile station being wirelessly connected to a radio access network; in response to the received message, selecting, in dependence upon the retrieved list of data functions, one of plural data functions residing in at least one gateway node coupled between the radio access network and an external data network; and sending at least one command to the selected data function to establish a session between the mobility management control node and the selected data function and to establish a data path between the radio access network and the selected data function, wherein the data path does not pass through the mobility management control node.
