Arranging internal data connections of office system
First Claim
1. A telecommunications system which comprises an office network and an operator network and a local area network between them, wherein the office network comprises at least one mobile system terminal, a base transceiver station, a radio access gateway controlling the base transceiver station and adapted to have a functional connection with the local area network and configured to adapt the data transmission protocols of said mobile system and local area network to each other, a call control entity, which is configured to control said radio access gateway through a signalling connection and arranged to detect the establishment of an internal data connection in the office network, which data connection uses a data protocol according to said mobile system;
- an interworking function to which a signalling connection from said call control entity is arranged and which interworking function is configured to adapt data connections according to the data protocol of at least said mobile system and coming from the radio access gateway to the data protocol according to said office network, in response to the call control entity detecting the establishment of an internal data connection in the office network, at least the second party of the data connection being said mobile system terminal, and the operator network is configured to adapt data transmission between the office network and a public land mobile network together.

Abstract
A method of establishing a data connection in a telecommunications system which comprises an office network and an operator network and a local area network between them. Data transmission between the office network and a public land mobile network is adapted together in the operator network. The office network comprises an interworking function to which a signalling connection from a call control entity is arranged, and the call control entity detects the establishment of an internal data connection in the office network, the data connection using a data protocol according to a mobile system. Data connections according to the data protocol and coming from a radio access gateway are adapted to the data protocol according to the office network in response to the call control entity detecting an internal data connection in the office network, the second party of the data connection being a mobile system terminal.

10. A method of establishing a data connection in a telecommunications system which comprises an office network and an operator network and a local area network between them, the office network comprising at least one mobile system terminal, a base transceiver station, a radio access gateway controlling the base transceiver station and adapted to have a functional connection with the local area network, a call control entity, an interworking function to which a signalling connection from said call control entity is arranged, the method comprising
controlling said radio access gateway by the call control entity through a signalling connection, detecting the establishment of an internal data connection in the office network by said call control entity, which data connection uses a data protocol according to said mobile system, adapting data connections according to the data protocol of at least said mobile system and coming from the radio access gateway are adapted to the data protocol according to said office network, in response to the fact that the call control entity detects the establishment of an internal data connection in the office network, at least the second party of the data connection being said mobile system terminal, and adapting the data transmission between the office network and a public land mobile network together in said operator network.
