First Claim
Patent Images
1. A method of communicating between a plurality of terminals and a communications network, the method comprising the steps of:
- receiving a request from at least one of the terminals for transmission resources from the communications network;
assigning the transmission resources; and
sending a block having a plurality of data fields from the communications network to at least one of the terminals the block containing a sending permission to indicate which of the terminals is permitted to send data to the communications network, characterised in that the sending permission has a first part present in a first field of the block and a second part present in a second field of the block.

Abstract
A GPRS system comprises a plurality of mobile terminals and a GPRS network. In order to obtain uplink radio resources, the mobile terminals send channel requests to the network and receive control blocks in return. The control blocks contain a number of fields, one of which, the uplink state flag field, contains the sending permissions. In order to extend the numbering space of the uplink state flag field, unused bits present in another field are used.

13. A communications network for communicating with a plurality of terminals,
wherein at least one of the terminals requests transmission resources from the communications network and the communications network sends a block having a plurality of data fields to the at least one of the terminals the block containing a sending permission to assign the transmission resources and to permit the at least one of the terminals to send data to the communications network, characterised in that the sending permission has a first part present in a first field of the block and a second part present in a second field of the block.

15. A computer program product for operating a communications network, the communications network communicating with a terminal, the computer program product comprising a computer readable medium having thereon:
-
computer executable code means to enable the communications network to receive a request for transmission resources from the terminal;
computer executable code means to enable the communications network to assign the transmission resources; and
computer executable code means to enable the communications network to send a block having a plurality of data fields to the terminal the block containing a sending permission to permit the terminal to send data to the communications network, characterised in that the computer program product comprises computer executable code means to enable the communications network to send the sending permission in two parts, a first part present in a first field of the block and a second part present in a second field of the block.

16. A method of operating a terminal to communicate with a communications network, the method comprising the steps of:
-
requesting transmission resources from the communications network;
receiving an assignment of the transmission resources; and
receiving a block having a plurality of data fields the block containing a sending permission to permit the terminal to send data to the communications network, characterised in that the sending permission has a first part present in a first field of the block and a second part present in a second field of the block.

17. A terminal for communicating with a communications network, wherein the terminal requests transmission resources from the communications network and the communications network sends a block having a plurality of data fields to the terminal the block containing a sending permission to assign the transmission resources and to permit the terminal to send data to the communications network,
characterised in that the sending permission has a first part present in a first field of the block and a second part present in a second field of the block.

19. A computer program product for operating a terminal to communicate with a communications network, the computer program product comprising a computer readable medium having thereon:
-
computer executable code means to enable the terminal to send a request for transmission resources from the communications network;
computer executable code means to enable the terminal to receive an assignment of the transmission resources from the communications network; and
computer executable code means to enable the terminal to receive a block having a plurality of data fields from the communications network the block containing a sending permission to permit the terminal to send data to the communications network, characterised in that the computer program product comprises computer executable code means to enable the terminal to receive the sending permission in two parts, a first part present in a first field of the block and a second part present in a second field of the block.

20. A method of communicating between a terminal and a communications network, the method comprising the step of sending a block having a plurality of data fields from the communications network to the terminal, the block containing an instruction,
characterised in that the instruction has a first part present in a first field of the block and a second part present in a second field of the block wherein the second field is used occasionally to send specific information other than the second part of the instruction and is not used at other times to send the specific information and the second part is sent when the second field is not used to send the specific information.
