US 9,313,828 B2 · Sensor network information collection via mobile gateway

Abstract

There is provided a sensor network information collection mechanism in which, after a UE has decided to become part of an information collecting operation for collecting information from a local sensor network, a signaling transmitted from a managing node of a local sensor network is received and processed. A communication network control element is informed about the willingness to become an information collector by sending a report message comprising measurement results derived from the signaling received from the managing node of the local sensor network. When receiving a gateway allocation message indicating that the UE is determined to be a gateway element to the local sensor network, the information collecting operation is started wherein sensor nodes of the local sensor network are woke up, and a traffic flow direction in the local sensor network is set in accordance with the managing node identity to which the UE is accessed.

Claims14

Dependent claims

A method, comprising:

transmitting, from a communication network sink, a message to at least one mobile equipment requesting information regarding availability as a gateway to a sensor network;
receiving, at the sink from a first one of the at least one mobile equipment, information relating to an availability of the first mobile equipment as a gateway to the sensor network via an identified first cluster head node;
transmitting, from the sink, a notice of gateway status to the first mobile equipment;
and
receiving, at the sink from the first mobile equipment, sensor information from the sensor network routed through the first cluster head node.

2 more elements

A mobile equipment, comprising:

a communication interface;
a memory including processor-readable instructions;
and
a processor configured to execute the processor-readable instructions from the memory, the instructions including instructions to:
communicate with a communication network control element via the communication interface;
receive from the control element a request to provide availability as a gateway to a sensor network;
detect beacon signals emitted from at least one cluster head node of a sensor network;
determine information regarding availability as a gateway for a first one of the at least one cluster head node based at least in part on the detected beacon signals;
transmit the information regarding availability to the control element;
receive from the control element a status indicator indicating an allocation of status as a gateway for the first one of the at least one cluster head node;
and
inform the sensor network of an updated network topology including identification of the first one of the at least one cluster head node.
