Abstract
A communication connection to a second user equipment (UE B) by a first user equipment (UE A) is requested, the request including a specific information element for an identification of UE B, a determination is made (S3) in a database on the basis of the specific information element identifying UE B's location within the communication network, a decision is made (S5, S6) whether UE B is reachable or accepts the communication connection or not, and if the decision is positive, the communication connection is established (S7) between UE A and UE B adapted to perform a packet data communication.
Claims10
A method for establishing a packet data communication connection in a communication network between a first user equipment and a second user equipment, said communication network comprising
- at least two access networks for establishing a data path between the communication network and the respective user equipment, said first user equipment being connected with one of said at least two access networks and said second user equipment being connected with the other one of said access networks,
- at least two serving GPRS support nodes for controlling a respective different one of said access networks, and
- at least one database for storing information used for a communication connection in said communication network and connected with said at least two serving nodes,
- said method comprising the steps of:
- requesting a communication connection to the second user equipment by the first user equipment to the respective serving GPRS support node, such a request including a specific fixed information element for an identification of the second user equipment,
- determining in said database on the basis of said specific fixed information element identifying the second user equipment a location of said second user equipment within the communication network at the respective other serving GPRS support node,
- deciding, whether said second user equipment is reachable or accepts the communication connection or not, and if the decision is positive,
- establishing the communication connection between the first and the second user equipment via a direct connection between said serving GPRS support nodes adapted to perform a packet data communication.
A device for performing a packet data communication in a communication network between a first user equipment and a second user equipment, said communication network comprising
- at least two access networks for establishing a data path between the communication network and the respective user equipment, said first user equipment being connected with one of said at least two access networks and said second user equipment being connected with the other one of said access networks, at least two serving GPRS support nodes for controlling a respective different one of said access networks, and
- at least one database for storing information used for a communication connection in said communication network and connected with said at least two serving nodes,
- said device comprising
- detection means for detecting a request for a communication connection to the second user equipment by the first user equipment, such a request including a specific fixed information element for an identification of the second user equipment,
- requesting/obtaining means for requesting and obtaining a location of said second user equipment within the communication network at the respective other serving GPRS support node from said database on the basis of said specific fixed information element identifying the second user equipment,
- connection requesting means for requesting a connection from said second user equipment and for deciding, whether said second user equipment is reachable or accepts the communication connection or not, and
- connection establishing/canceling means for establishing the communication connection between the first and the second user equipment via a direct connection between said serving GPRS support nodes adapted to perform a packet data communication.
