The invention relates to a method to process data packets of a vehicle message received by a privacy gateway () from a vehicle () via a mobile communications network (). The method comprises the following steps: The vehicle message transmitted by the vehicle () is received. A source IP address in the data packets of the vehicle message is identified. The source IP address in the data packets of the vehicle message is replaced by an IP address of a location collecting entity () of the mobile communications network (). Said mobile communications network collects location information of a plurality of vehicles () resulting in an adapted vehicle message with adapted data packets containing the IP address of the location collecting entity as source IP address. Then, the adapted vehicle message is transmitted to a service providing entity () which is configured to provide location dependent services for the plurality of vehicles.

Privacy protection gateway for vehicles

Spatial information associated with a terminal connected to a network via a radio link is monitored. Depending on the spatial information and further depending on spatially-resolved quality of a data transmission, it is selected between operation of the data transmission in the first mode and in a second mode.

Spatially-resolved quality of data transmission

A method for broadcasting an event message to a geographical area comprising the steps of receiving (S) an event message with geographical information for which the event message is relevant; requesting (S) information about available service areas and/or logical areas, wherein at least one logical area is covered by a service area; determining (S) at least one affected geographical area based on the geographical information of the event message and the received service and/or logical areas; and providing (S) the event message to the at least one affected geographical area.

Provision of an event message to a user

Providing a network service to at least one mobile terminal inside a service area, the at least one mobile terminal being arranged to communicate with a communication network, the service area being a part of a geographical area that is covered by the communication network, comprising defining, by a first grid process, a first grid with first grid lines, the first grid covering at least a part of the service area with one or more tiles framed by the first grid lines; defining, by a second grid process, a second grid with second grid lines, the second grid covering at least a part of the service area with one or more tiles framed by the second grid lines; monitoring a crossing, by the at least one mobile terminal, of a grid line; and determining whether said grid line is a first grid line or a second grid line for notifying correspondingly the first grid process and/or the second grid process.

Localized network service

A device moving in a space determines one or more zones around it, wherein the one or more zones are linked to the device and move together with the device through the space. The device detects if a border of a first of the one or more zones starts to intersect or stops to intersect with a border of an area inside the space. If the detecting is affirmative, the device transmits information related to the intersection. An apparatus receives this information from the device and adapts a status value of the area in dependence of the received information.
