Communications terminal and method

摘要

A mobile communications network can establish one or more communications bearers for communicating data packets to/from a communications terminal via a radio network and a core network, each of the communications bearers established using context information associated with connections from the communications terminal to destination addresses, or to the communications terminal from source addresses. The communications terminal can, in an idle state, communicate a short signalling message data packet to a base station of the radio network, using predetermined parameters for configuring a mobile communications terminal transmitter, which correspond with parameters with which a receiver in the base station can receive the short message data packet, the short message data packet including an indication of context information usable by the mobile communications network for communicating the short message data packet to a mobility manager of the mobile communications network. The short message data packet can be context-less or quasi-context-less.

主权项

1. A communications terminal for communicating data packets to or from a mobile communications network via a radio access interface, the mobile communications network comprising:
radio network circuitry including a plurality of base stations configured to communicate data packets to or from communications terminals, including the communications terminal, via the radio access interface, and core network circuitry configured to communicate the data packets to destination addresses from the radio network circuitry or to communicate the data packets to the radio network circuitry from source addresses, the mobile communications network being configured to establish one or more communications bearers for communicating the data packets to or from the communications terminal via the radio network circuitry and the core network circuitry, each of the one or more communications bearers being established using context information associated with one or more connections from the communications terminal to the destination addresses, or to the communications terminal from source addresses, wherein the communications terminal is configured to when in an idle state, communicate a short message data packet to one of the base stations of the radio network circuitry as a signaling message using predetermined parameters for configuring a transmitter of the mobile communications terminal, which correspond with parameters with which a receiver in the base station is configured to receive the short message data packet, the short message data packet including an indication of context information for use by the mobile communications network for communicating the short message data packet to a Mobility Management Entity (MME) of the mobile communications network, and wherein the predetermined parameters for configuring the transmitter of the communications terminal with the effect that the short message data packet is communicable to the base station include at least one of a power control level setting a power with which a radio signal representing the short message data packet is transmitted, modulation and encoding of the short message data packet for communicating the short message data packet from the communications terminal to the base station using the radio signal.
