1. A method for routing data in a communication system, the method comprising the steps of:
- determining that a first remote unit needs to communicate with a second remote unit, wherein the first remote unit is a mobile unit;
determining an availability of the second remote unit within a local network, wherein the first remote unit is part of the local network;
transferring a routing function from a packet data gateway to a Base Station System, based on the determination that the second remote unit is within the local network so that data can be routed from the first remote unit to the second remote unit via the BSS without routing the data through the packet data gateway, wherein transferring the routing function comprises transferring context information that comprises mobility and security information.

Abstract
The present invention provides a method for routing data from a service request in a communication system. A context is transferred from a packet data gateway, such as a Serving GPRS (GSM Packet Radio Service) Support Node (SGSN), to a Base Station System (BSS) coupled thereto. The context specifies where data for this user should be sent. The service request is received at the BSS and includes data. The data from the service request is routed to an appropriate location, based at least in part upon the context.
