Abstract
The present invention relates to an arrangement, in a communications system supporting communication of packet data, for selection of a packet data gateway node or function for a mobile user station (MS; UE). It comprises a packet data gateway functional selection means, said gateway functional selection means is adapted to use a number of information parameters contained in a context set up message to select packet data gateway, and it is adapted to forward the context set up message to the selected packet data gateway node or packet data gateway function.
Claims18
An arrangement, in a communications system supporting communication of packet data, for selection of a packet data gateway node or function for a mobile user station (MS;
- UE), comprising:
- a packet data gateway functional selection means, said gateway functional selection means adapted to use a plurality of information parameters contained in a context set up message to select a packet data gateway, and to forward the context setup message to the selected packet data gateway node or a packet data gateway function.
A gateway functional selection means for use in a communications system supporting communication of packet data and for selection of packet data gateway node or function, comprising:
- means to communicate with a number of SGSN:s, or SGSN functional parts of CGSN:s and with a number of GGSN:s or GGSN functional parts of CGSN:s;
- means to select GGSN, or GGSN functional part of a CGSN, from a number of GGSN:s or CGSN:s, available for a given Access Point Name (APN) using one or more additional information parameters contained in a context set up message received from a SGSN, or the SGSN part of a CGSN.
A method for, in a communications system supporting communication of packet data, selecting packet data gateway node or gateway function for a mobile user station, comprising the steps of:
- receiving a request for activation of a context from the mobile user station in an SGSN or SGSN part of a CGSN, said request containing a number of information parameters,
- using at least a number of, preferably at least two, of said information parameters to select a gateway node or function in a functional selection means,
- forwarding the create context request to the selected gateway node or function.
