Allocation of radio resources from a network in a packet switched data transmission
First Claim
1. A method for allocating radio resources in a packet-switched data transmission system, in which system a terminal is capable of communicating with a network over a radio interface by using packet transfer mode, wherein the method comprises:
- generating a radio resource request for allocating a radio resource to the terminal for packet-switched communication;
sending the radio resource request from the terminal to the network, whereinthe radio resource request comprises an express indication that the radio resource is requested for a real-time service, and whereinthe radio resource request is implemented by a protocol layer, which defines procedures that enable radio resources to be allocated and divided among multiple users, and is required to establish a temporary open ended connection for the terminal utilizing unacknowledged radio link control upon receipt of the radio resource request so that in response to the radio resource request the packet-switched communication may be used for open ended real-time service utilizing unacknowledged radio link control avoiding the establishment and release of a close ended connection of a specific length and achieving a short transmission delay.

Abstract
A method is provided for allocating a radio resource in a packet switched data transmission system, such as GPRS (General Packet Radio Service), which data transmission system includes terminals and a network. In the method, terminals communicate with the network over the radio interface using the packet transfer mode, and for communication, a radio resource is allocated to the terminal. For allocating the radio resource, for the packet switched implementation of a realtime service, a first message is transmitted from the terminal to the network and the first message is received in the network. The network identifies the first message as a radio resource request for the packet switched implementation of a realtime service and allocates to the terminal the requested radio resource for the packet switched implementation of the realtime service. A wireless terminal and network element relating to the method are also provided.

5. A method for allocating radio resources in a packet-switched data transmission system, in which system a terminal is capable of communicating with a network over a radio interface by using packet transfer mode, wherein the method comprises:
-
receiving at the network a radio resource request sent by the terminal for allocating a radio resource to the terminal for packet-switched communication, wherein the radio resource request comprises an express indication that the radio resource is requested for a real-time service, wherein the method comprises; allocating, by a network element, the requested radio resource for packet-switched implementation of a real-time service, and wherein the radio resource request is implemented by a protocol layer which defines procedures that enable radio resources to be allocated and divided among multiple users, and is required to establish a temporary open ended connection for the terminal utilizing unacknowledged radio link control upon receipt of the radio resource request so that in response to the radio resource request the packet-switched communication may be used for open ended real-time service utilizing unacknowledged radio link control avoiding the establishment and release of a close ended connection of a specific length and achieving a short transmission delay. - View Dependent Claims (6, 7, 8, 19)

9. A terminal for communication, wherein the terminal is configured for communication with a network over a radio interface by using packet transfer mode, the terminal comprising:
-
a processor for generating a radio resource request for allocating radio resource to the terminal for packet-switched communication, the radio resource request including an express indication that the radio resource is requested for a real-time service; a transmitter for sending the radio resource request from the terminal to the network; wherein the network comprises a protocol layer for defining procedures that enable radio resources to be allocated and divided among multiple users, the protocol layer being required to establish a temporary open ended connection for the terminal in response to said radio resource request, wherein the terminal is further configured to receive an assignment message establishing the required temporary open ended connection utilizing unacknowledged radio link control for the terminal so that in response to the radio resource request the packet-switched communication may be used for open ended real-time service utilizing unacknowledged radio link control avoiding the establishment and release of a close ended connection of a specific length and achieving a short transmission delay. - View Dependent Claims (10, 11, 12, 13, 14, 20)
