Abstract

A mobile communications terminal communicates data using a mobile communications network that includes base stations and mobility managers that can send and receive signalling packets for controlling user data communications between communications terminals and a destination. The communications terminal can communicate packets with the base stations via a wireless access interface provided by the base stations and send a signalling packet to the mobility managers, the signalling packet including user data intended for a destination, prior to establishing a signalling connection with the mobility managers. The mobility managers can, upon receiving a signalling packet from a communications terminal, detect the packet is not associated with any established signalling connection between the mobility managers and the communication device. The mobility managers can, responsive to the detection, transmit the user data in the signalling packet to the destination. Accordingly a short message may be sent in a reduced context or context-less manner.

Claims

1. A mobile communications terminal for communicating data in a mobile communications network, the mobile communications network comprising one or more base stations operable to provide a wireless access interface for the mobile communications terminal;

and one or more mobility managers operable to send and receive signalling packets for controlling user data communications between the mobile communications terminal and a destination, wherein the mobile communications terminal comprising;

a transmitter;

a receiver; and

a processor that executes instructions stored in a memory to

communicate, via the transmitter and the receiver, packets with one or more base stations in a mobile communications system via the wireless access interface provided by the one or more base stations;

send, via the transmitter, a signalling packet to one or more mobility managers of the mobile communications network, the signalling packet comprising user data intended for the destination, prior to establishing a signalling connection with the one or more mobility managers; and

include in the signalling packet an indication that the signalling packet is part of a conversation comprising a predetermined number of packets, the signalling packet being included in the predetermined number of packets.

2. The mobile communications terminal according to claim 1, wherein the predetermined number of packets is any integer equal to or greater than one.

3. The mobile communications terminal according to claim 1, wherein the circuitry is configured to include, in the signalling packet, information in respect of an identity of the mobile communications terminal for use in identifying the mobile communications terminal in the absence of a signalling connection with the one or more mobility managers.

4. The mobile communications terminal according to claim 1, wherein the circuitry is configured to include, in the signalling packet, information in respect of an identity of the destination for use in routing the user data in the absence of a signalling connection with the one or more mobility managers.

5. The mobile communications terminal according to claim 1, wherein one of the one or more mobility managers is a Mobility Management Entity (MME).

6. A mobile communications terminal for communicating data in a mobile communications system, the mobile communications terminal comprising:

a transmitter;

a receiver; and

a processor that executes instructions stored in a memory to

communicate, via the transmitter and the receiver, packets with one or more base stations in the mobile communications system via a wireless access interface provided by the one or more base stations;

send, via the transmitter, a signalling message to the one or more base stations, the signalling message comprising user data intended for a destination, prior to establishing any signalling connection with the one or more base station; and

include in the signalling message an indication that the signalling message is part of a conversation comprising a predetermined number of packets, the signalling message being included in the predetermined number of packets.

7. The mobile communications terminal according to claim 6, wherein the predetermined number of packets is any integer equal to or greater than one.

8. The mobile communications terminal according to claim 6, wherein the circuitry is configured to include, in the signalling message, information in respect of an identity of the mobile communications terminal for use in identifying the mobile communications terminal in the absence of a signalling connection with the one or more base stations.

9. The mobile communications terminal according to claim 6, wherein the circuitry is configured to include, in the signalling message, information in respect of an identity of the destination for use in routing the user data in the absence of a signalling connection with the one or more base stations.

10. The mobile communications terminal according to claim 6, wherein the mobile communications terminal is a 3GPP-compliant terminal.

11. The mobile communications terminal according to claim 6, wherein the mobile communications terminal is a LTE-compliant terminal.

12. A method of operating a mobile communications terminal in a mobile communications system, the method comprising:

communicating, with a processor that executes instructions stored in a memory via a transmitter and receiver of the mobile communications terminal, packets with one or more base stations in the mobile communications system via a wireless access interface provided by the one or more base stations;

sending, with the processor via the transmitter of the mobile communications terminal, a signalling packet to one or more mobility managers of the mobile communications system, the signalling packet comprising user data intended for a destination, prior to establishing any signalling connection with the one or more mobility managers; and

including, using the processor of the mobile communications terminal, in the signalling packet an indication that the signalling packet is part of a conversation comprising a predetermined number of packets, the signalling packet being included in the predetermined number of packets.

13. The method of operating the mobile communications terminal according to claim 12, wherein the predetermined number of packets is any integer equal to or greater than one.

14. The method of operating the mobile communications terminal according to claim 12, the method comprising including, in the signalling packet, information in respect of an identity of the mobile communications terminal for use in identifying the mobile communications terminal in the absence of a signalling connection with the one or more mobility managers.

15. The method of operating the mobile communications terminal according to claim 12, the method comprising including, in the signalling packet, information in respect of an identity of the destination for use in routing the user data in the absence of a signalling connection with the one or more mobility managers.

16. The method of operating the mobile communications terminal according to claim 12, wherein one of the one or more mobility managers is a Mobility Management Entity (MIME).

17. A method of operating a mobile communications terminal in a mobile communications system, the method comprising:

communicating, with a processor that executes instructions stored in a memory via a transmitter and a receiver of the mobile communications terminal, packets from the mobile communications terminal with one or more base stations in the mobile communications system via a wireless access interface provided by the one or more base stations;
