1. A context providing method comprising:
- recording, in a context holding unit, a plurality of context information, wherein each context information includes a context entity identifier for distinguishing a context entity from other context entities, various information representing a state of the context entity, and association information;
receiving a request for information representing the state of a first context entity;
using a context generation unit, in response to the received request, from said context holding unit,extracting the context information of the first context entity,extracting the context information of a second context entity which is registered as the association information in the context information of the first context entity, andexecuting, at least once, a process of extracting the context information of a third context entity which is registered as the association information in the extracted context information excluding the context information of the first context entity, but not registered as the association information in the context information of the first context entity, to determine, as the information representing the state of the first context entity, the information contained in any of the extracted context information; and
sending back the information determined by said context generation unit to respond to the request.

Abstract
A context providing method includes the collection step of collecting context information representing a situation of a target via a network, the generation step of applying a predetermined rule to the collected context information and information associated with a context entity which generates/utilizes the context information, thereby generating new context information, and the step of transmitting the generated context information to a context requester via the network. A context providing system and apparatus are also disclosed.

1. A context providing method comprising:
-
recording, in a context holding unit, a plurality of context information, wherein each context information includes a context entity identifier for distinguishing a context entity from other context entities, various information representing a state of the context entity, and association information; receiving a request for information representing the state of a first context entity; using a context generation unit, in response to the received request, from said context holding unit, extracting the context information of the first context entity, extracting the context information of a second context entity which is registered as the association information in the context information of the first context entity, and executing, at least once, a process of extracting the context information of a third context entity which is registered as the association information in the extracted context information excluding the context information of the first context entity, but not registered as the association information in the context information of the first context entity, to determine, as the information representing the state of the first context entity, the information contained in any of the extracted context information; and sending back the information determined by said context generation unit to respond to the request. - View Dependent Claims (2, 3, 4, 5)

6. A context providing system comprising:
- a radio communication system connected to a network; and
a context providing apparatus comprising;
a context holding unit comprising a memory device, the context holding unit configured to record a plurality of context information, wherein each context information includes a context entity identifier for distinguishing a context entity from other context entities, various information representing a state of the context entity, and association information;
a context request reception unit configured to receive a request for information representing the state of a first context entity;
a context generation unit configured to, in response to the request received by said context request reception unit, from said context holding unit, extract the context information of the first context entity, extract the context information of a second context entity which is registered as the association information in the context information of the first context entity, and execute, at least once, a process of extracting the context information of a third context entity which is registered as the association information in the extracted context information excluding the context information of the first context entity, but not registered as the association information in the context information of the first context entity, to determine, as the information representing the state of the first context entity, the information contained in any of the extracted context information; and
a context transmission unit configured to send back the information determined by said context generation unit to respond to the request. - View Dependent Claims (7, 8, 9, 10)

11. A context providing apparatus comprising:
- a context holding unit comprising a memory device, the context holding unit configured to record a plurality of context information, wherein each context information includes a context entity identifier for distinguishing a context entity from other context entities, various information representing a state of the context entity, and association information;
a context request reception unit configured to receive a request for information representing the state of a first context entity;
a context generation unit configured to, in response to the request received by said context request reception unit, from said context holding unit, extract the context information of the first context entity, extract the context information of a second context entity which is registered as the association information in the context information of the first context entity, and execute, at least once, a process of extracting the context information of a third context entity which is registered as the association information in the extracted context information excluding the context information of the first context entity, but not registered as the association information in the context information of the first context entity, to determine, as the information representing the state of the first context entity, the information contained in any of the extracted context information; and

16. A non-transitory computer-readable medium having computer-readable instructions stored thereon that, upon execution by a processor, cause the processor to:
-
record, in a context holding unit, a plurality of context information, wherein each context information includes a context entity identifier for distinguishing a context entity from other context entities, various information representing a state of the context entity, and association information; receive a request for information representing the state of a first context entity; instruct a context generation unit to, in response to the received request, from said context holding unit, extract the context information of the first context entity, extract the context information of a second context entity which is registered as the association information in the context information of the first context entity, and execute, at least once, a process of extracting the context information of a third context entity which is registered as the association information in the extracted context information excluding the context information of the first context entity, but not registered as the association information in the context information of the first context entity, to determine, as the information representing the state of the first context entity, the information contained in any of the extracted context information; and send back the information determined by said generation context unit to respond to the request. - View Dependent Claims (17, 18, 19, 20)
