Abstract:
1. A telecommunications system for providing a facility for communicating internet packets to and/or from a mobile user equipment, payload data of the internet packets comprising a plurality of different types of data, the system comprising a packet radio network which includes a gateway support node, a serving support node and a radio network controller, the gateway support node for providing an interface for communicating the internet packets between the mobile user equipment and the packet data network, the serving support node for controlling communication of the internet packets between the gateway support node and the mobile user equipment using a radio network controller, the radio network controller for providing radio access bearers for communicating the internet packets to and from the mobile user equipment, wherein the gateway support node in combination with the serving support node for responding to context application request data from the mobile user equipment to establish a virtual communications channel between the gateway support node and the mobile user equipment via the serving support node, the context application request data representing a request for the virtual communications channel for communicating the internet packets containing the different types of data, the context application request data specifying a main set of quality of service parameters and including at least one other data field representing a request for a different set of quality of service parameters, each set of quality of service parameters being provided for one of the different types of data in the internet packet, the virtual communications channel including a bearer for communicating the internet packets between the gateway support node and the serving support node and a plurality of radio access bearers, each of the radio access bearers being provided for one of the different types of payload data of the internet packets, each radio access bearer providing one of the main and other set of quality of service parameters for the different data types specified by the context application request data, and the serving support node, in response to the context application request data from the mobile user equipment, parses an internet packet addressed to the mobile user equipment comprising an internet protocol header and a plurality of different types of data, to generate a payload data types indicator in which the payload data type indicator is a representation of payload types information describing the different types of payload data in the internet packet addressed to the mobile user equipment and append the payload data types indicator to the internet packet addressed to the mobile user equipment, and to send the internet packet addressed to the mobile user equipment with the appended payload data types indicator to the radio network controller via the virtual communications channel, and the radio network controller identifies the payload data types indicator, and in accordance with the payload data types indicator, to provide each of the different types of payload data of the internet packet addressed to the mobile user equipment to a corresponding radio bearer.
