Wireless communication terminal and method for wireless communication
The invention provides for a wireless communications terminal ( 502 ), and related system and method, for wirelessly communicating with a network ( 504, 506 ). The terminal ( 502 ) is arranged to transmit, as part of a wireless connection establishment procedure for forming a wireless connection between the terminal ( 502 ) and the network ( 504, 506 ), wireless-connection establishment signalling ( 510 ) including a small-data indicator to indicate to the network ( 504 ) that transmission of an amount of data below a threshold value is required from the terminal ( 502 ) by way of the wireless connection to the network ( 504, 506 ).
1. A user equipment (UE) arranged to wirelessly communicate with a network, the UE being arranged to transmit a Radio Resource Control (RRC) Connection Request message as part of a wireless connection establishment procedure for forming a wireless connection between the UE and the network,
the RRC Connection Request message including an RRC establishment cause, wherein the RRC establishment cause is configurable to include any of a plurality of different cause indicators including: a mobile originating signalling (mo-signalling) indicator; a mobile terminating access (mt-Access) indicator; a mobile originating data (mo-data) indicator; and a delay tolerant access indicator; and at least one further indicator of mobile originating data associated with the UE when operating in machine type communication mode.
2. A method of operating a user equipment (UE) arranged to wirelessly communicate with a network, including the steps of:
transmitting a Radio Resource Control (RRC) Connection Request message as part of a wireless connection establishment procedure for forming a wireless connection between the UE and the network,
the RRC Connection Request message including an RRC establishment cause, wherein the RRC establishment cause is configurable to include any of a plurality of different cause indicators including: a mobile originating signalling (mo-signalling) indicator; a mobile terminating access (mt-Access) indicator; a mobile originating data (mo-data) indicator; and a delay tolerant access indicator; and at least one further indicator of mobile originating data associated with the UE when operating in machine type communication mode.
3. A method of small-data wireless communications between a user equipment (UE) and a network device in a communications network, and including the steps of transmitting from the UE, a Radio Resource Control (RRC) Connection Request message as part of a wireless connection establishment procedure for forming a wireless connection between the UE and the network, the RRC Connection Request message including an RRC establishment cause, wherein the RRC establishment cause is configurable to include any of a plurality of different cause indicators including: a mobile originating signalling (mo-signalling) indicator; a mobile terminating access (mt-Access) indicator; a mobile originating data (mo-data) indicator; and a delay tolerant access indicator; and at least one further indicator of mobile originating data associated with the UE when operating in machine type communication mode, and including operating the UE according to the method of claim 2 .
4. A method of small-data wireless communications between a user equipment (UE) and a network device in a communications network, and including the steps of:
transmitting from the UE, a Radio Resource Control (RRC) Connection Request message as part of a wireless connection establishment procedure for forming a wireless connection between the UE and the network, the RRC Connection Request message including an RRC establishment cause, wherein the RRC establishment cause is configurable to include any of a plurality of different cause indicators including: a mobile originating signalling (mo-signalling) indicator; a mobile terminating access (mt-Access) indicator; a mobile originating data (mo-data) indicator; and a delay tolerant access indicator; and at least one further indicator of mobile originating data associated with the UE when operating in machine type communication mode.
