Abstract:
The present invention relates to a method for the notification of a resource subscription in a machine-to-machine (M2M) system and devices for same, the method comprising the steps of: detecting a change in the resources to subscribe to comprising a subscription resource as a child resource; generating a notification message including a value indicating the event category of the change in accordance with the second attribute information configured in the subscription resource; and determining if a reception device is reachable on the basis of the scheduling information configured in a scheduling resource for an M2M device and the scheduling information configured in a scheduling resource for the reception device, wherein: if the reception device is determined to be reachable on the basis of the scheduling information, the notification message is immediately transmitted to the reception device; and if the reception device is determined to be unreachable on the basis of the scheduling information, the notification message is processed by the M2M device according to the value of the first attribute information configured in the subscription resource, and the processed notification message is transmitted to the reception device after the reception device is recovered to a reachable state.
Abstract:
The present invention relates to a method and apparatus for modifying a machine-to-machine (M2M) service setting in an M2M system, comprising the steps of: transmitting at least one policy information to at least one device, wherein each of the at least one policy information comprises scope information and condition information; and if the state of an M2M gateway corresponds to a state of which the condition information is indicative, transmitting a first notification indicative of a state change of the M2M gateway to a device of which the scope information is indicative.
Abstract:
The present invention relates to a method for calculating trip paths determined by a departure point and a target point by using traffic information in a terminal. The method includes the steps of: requesting traffic information related to a trip from a server; receiving the traffic information related to the trip from the server; and calculating the paths by using the received traffic information, wherein the received traffic information includes traffic events corresponding to information on disturbances in the traffic flow in an area or the path related to the trip, and performance parameters corresponding to information on traffic flow in a road segment within a constant radius from the departure point, and wherein the performance parameters can be received from the server in the case where there is congestion heavier than a predetermined level within a constant radius from the departure point.
Abstract:
According to one embodiment of the present invention, a method for calculating the location of a terminal in a wireless communication system, which is to be performed by the terminal, comprises the steps of: transmitting, to a location server, a request for location estimation assist data for calculating the location of the terminal; receiving the location estimation assist data from the location server; and calculating the location of the terminal using the location estimation assist data. The location estimation assist data includes radio map information including a received signal strength (RSS) value from each access point collected at a plurality of location estimation reference points in a region having a predetermined range. The radio map includes information regarding the location estimation reference points (hereinafter, referred to as “update points”) which require an update of the radio map. The method may further include a step of determining whether or not an update of the location estimation assist data is required based on the calculated location of the terminal and the information regarding the update points.
Abstract:
Provided is a method for providing update information for a route from a terminal to a destination to the terminal, wherein the destination is designated as location of the third party being moving, which is performed by a server and comprising: receiving location information of the terminal from the terminal; determining whether the location of the third party has been changed; generating update information for the route based on the received location information and the changed location of the third party upon determining that the location of the third party has been changed; and notifying the terminal of the update information according to types of the update information, wherein the location information of the terminal is received when the terminal deviates from or detours around the route, when the terminal enters a specific segment on the route set by the server, or when the terminal moves by a predetermined distance.
Abstract:
A method for re-arrangement of a group resource of an M2M device arranged according to a hierarchical tree structure is disclosed in accordance with one embodiment of the present invention. The method is performed by a first M2M device which owns a first group resource, and the method comprises the steps of: receiving, from a second M2M device, a specific request message for the first group resource; determining whether it is necessary to transfer at least one member of the first group resource as a member of a group resource of another M2M device; determining, in order to transfer the at least one member as a member of the group resource of the another M2M device, whether to use a group resource existing in the another M2M device or whether to generate a new group resource in the another M2M device; and if a new group resource is generated in the another M2M device, adding the at least one member as a member of the new group resource, wherein the first group resource is added as a member of the new group resource if the another M2M device is higher than the first M2M device in the hierarchical tree structure, and the new group resource is added as a member of the first group resource if the another M2M device is lower than the first M2M device in the hierarchical tree structure.
