Controlling data transmissions for machine type communications in a mobile communication system
First Claim
1. A method for controlling transmission of machine type communication data to or from machine type communication devices within a mobile communication system, wherein the method comprises:
- receiving, by a network node in a radio access network or core network of the mobile communication system, a first connection request message in a control plane from a mobile terminal, wherein the first connection request message requests establishment of a connection between the network node and the mobile terminal for transmitting timeslot information, indicates that the mobile terminal is a machine type communication device and includes a connectivity duration field indicating an estimated connectivity duration for transmitting machine type communication data per connection request;
receiving, by the network node, load information that either indicates an estimated load of the mobile communication system at different future timeslots or provides real time load information from which the estimated load can be determined;
determining, by the network node, future timeslots for transmitting machine type communication data based on the load information and the first connection request message, including the connectivity duration field, wherein the determined future timeslots are one or more timeslots for which a maximum load count has not been reached;
transmitting, by the network node, in the control plane and to the mobile terminal, a first connection setup message that informs the mobile terminal regarding the determined future timeslots;
receiving, in response to the first connection setup message and in the control plane, a connection setup complete message from the mobile terminal accepting one of the determined future timeslots; and
increasing a load count for the accepted timeslot in response to receiving the connection setup complete message.

Abstract
The invention relates to methods for controlling transmission of machine type communication data to or from machine type communication devices within a mobile communication system. Furthermore, the invention relates to a mobile terminal and network node for implementing such methods, and to implementations of the methods in software. In one aspect of the invention, a mechanism to perform transmission planning (or scheduling) of data transmission from machine type communication devices is suggested. This transmission planning may be based on load estimates at different points in time (e.g. for individual timeslots), and may allow the scheduling of transmissions of machine type communication data at points in time, where the load in the mobile/wireless communication network is expected to be low.
