Abstract

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 signaling ( 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 ).

First claim

The invention claimed is:

1. A user equipment (UE) arranged to wirelessly communicate with a network, the UE having a configuration to:
operate in a small data transmission mode in which the UE supports small data transmission, and
transmit, when operating in said small data transmission mode, an RRC Connection Request message as part of a wireless connection establishment procedure for forming a wireless connection between the UE and the network,
wherein said RRC Connection Request message includes 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 originating data (mo-data) indicator, and
at least one further indicator of mobile originating data that is used for the UE when operating in said small data transmission mode.

2. The user equipment according to claim 1 , wherein the at least one further indicator of mobile originating data is associated with the UE when operating in a machine type communication mode.

3. The user equipment according to claim 1 , wherein the plurality of different cause indicators include a mobile terminating access (mt-Access) indicator.

4. The user equipment according to claim 1 , wherein the plurality of different cause indicators include a delay tolerant access indicator.

5. A method of operating a user equipment (UE) arranged to wirelessly communicate with a network, the method including the steps of:
operating in a small data transmission mode in which the UE supports small data transmission; and
transmitting, when operating in said small data transmission mode, an RRC Connection Request message as part of a wireless connection establishment procedure for forming a wireless connection between the UE and the network,
wherein said RRC Connection Request message includes an RRC establishment cause, and
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 originating data (mo-data) indicator, and
at least one further indicator of mobile originating data that is used for the UE when operating in said small data transmission mode.

6. The method according to claim 5 , wherein the at least one further indicator of mobile originating data is associated with the UE when operating in a machine type communication mode.

7. The method according to claim 5 , wherein the plurality of different cause indicators include a mobile terminating access (mt-Access) indicator.

8. The method according to claim 5 , wherein the plurality of different cause indicators include a delay tolerant access indicator.

9. A network device arranged to wirelessly communicate with a user equipment (UE), where said UE is arranged to operate in a small data transmission mode in which the UE supports small data transmission, the network device having a configuration to:
receive an RRC Connection Request message as part of a wireless connection establishment procedure for forming a wireless connection between the UE, operating in said small data transmission mode, and the network,
wherein said RRC Connection Request message includes 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 originating data (mo-data) indicator, and
at least one further indicator of mobile originating data that is used for the UE when operating in said small data transmission mode.

10. The network device according to claim 9 , wherein the at least one further indicator of mobile originating data is associated with the UE when operating in a machine type communication mode.

11. The network device according to claim 9 , wherein the plurality of different cause indicators include a mobile terminating access (mt-Access) indicator.

12. The network device according to claim 9 , wherein the plurality of different cause indicators include a delay tolerant access indicator.

13. A wireless communication system, comprising:
the user equipment (UE) according to claim 1 ; and
a network device arranged to wirelessly communicate with the user equipment, the network device being arranged to receive the RRC Connection Request message.

14. The wireless communication system according to claim 13 , wherein the at least one further indicator of mobile originating data is associated with the UE when operating in a machine type communication mode.

15. The wireless communication system according to claim 13 , wherein the plurality of different cause indicators include a mobile terminating access (mt-Access) indicator.

16. The wireless communication system according to claim 13 , wherein the plurality of different cause indicators include a delay tolerant access indicator.
