US 2006/0135159 A1 · Method and mobile radio communication network for the transmission of packet data

Abstract

The invention relates to a method for controlling the exchange of data between mobile subscribers in a packet-oriented mobile communication network, wherein management of each subscriber occurs at a specific control node (SGSN) of the mobile communication network according to the actual whereabouts of the subscriber inside the mobile communication network; links from/to a mobile communication transmitter device of the mobile subscriber are controlled inside the mobile communication network by the corresponding control node; wherein an address register comprising all of the addresses allocated to mobile subscribers managed by said control node is stored in the control network node; a destination address allocated to the data packets is read out in the control network node from incoming data packets and is compared to the address register by means of a search function; if the destination address is available in the address register, the data packets are exclusively handled by the control node in the mobile communication network and are further transmitted; if the destination address is missing in the address register, the data packets are transmitted by the control node to another network node (GGSN) of the mobile communication network for further processing

Dependent claims

A method for controlling data interchange between mobile subscribers (A, B) in a packet-oriented mobile communication network, where

each subscriber (A, B) is managed at a particular control network node (SGSN) in the mobile communication network on the basis of his respective current location in the mobile communication network,
connections from/to a mobile communication terminal associated with the mobile subscriber (A, B) are controlled (SGSN) within the mobile communication network by the appropriate control network node,
in which
the control network node (SGSN) stores an address register containing all of the addresses associated with the mobile subscribers (A, B) managed by the control network node (SGSN),
the control network node (SGSN) takes incoming data packets and reads a destination address associated with the data packets, and uses a search function to compare said destination address with the address register,
if the destination address is present in the address register then the data packets are handled and forwarded within the mobile communication network exclusively by the control network node (SGSN),
if the destination address is absent from the address register then the data packets are routed from the control network node (SGSN) to a further network node (GGSN) in the mobile communication network for the purpose of further handling.
