SENSOR NETWORK INFORMATION COLLECTION VIA MOBILE GATEWAY
First Claim
1. An apparatus, comprising:
- a routing processing portion configured to adjust a traffic flow direction in accordance with network topology information transmitted from a communication network element, wherein the network topology information indicates a cluster head node identification identifying at least one network node acting as a cluster head node for a local sensor network,wherein the routing processing portion is further configured to determine a next destination node for a data traffic flow in the local sensor network on the basis of the cluster head node identification.

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.

9. A non-transitory computer readable storage medium embodied with computer executable code, which when executed on a computer, performs the steps of:
-
receiving from a communication network element an accessing request for requesting allocation as a gateway element for collecting information from a local sensor network, the accessing request comprising a report of measurement results regarding a signaling received by the communication network element from a managing node of the local sensor network, determining whether the communication network element is to be selected as a gateway element, and sending, in response to the accessing request, a gateway allocation message informing that the communication network element is determined to be a gateway element to the local sensor network.
