Abstract: The invention discloses a method of sending pictures for display individually or as a series of pictures in a mini-clip on a receiving device during a lengthy file transfer. The invention, although not strictly limited to, is particularly suitable for use in a Bluetooth environment using the Object Exchange (OBEX) protocol. In an embodiment of the invention, a picture or series of pictures (710,720,730) are encapsulated within a Application Parameters header of the ongoing long file transfer. When picture data is too large to fit into a single header the data may be segmented and spanned over several headers. The headers contain parameters that define display characteristics such as picture display time and mini-clip or series refresh rate, thereby lending the method particularly well for the display of advertising content.

Abstract: When an ad hoc network is formed between short range wireless devices, at least one device assumes the role of an ad hoc network information provider for the new piconet. In this role, the device allocates a browsing hierarchy of service classes in its service registry. The service classes will provide a record to characterize the ad hoc network. When a new wireless device arrives within the communication range of any member of the ad hoc network, its inquiry signals are answered by the first member detecting the inquiry. If that first member is an ad hoc network information provider, it responds with information accessed from its service registry characterizing the ad hoc network. If, instead, an ordinary device in the ad hoc network is the first to respond to the inquiry signals of the arriving device, the device responds with the address of the ad hoc network information provider. The arriving device then pages the ad hoc network information provider to obtain information characterizing the ad hoc network.

Abstract: The invention concerns a method of communicating between an access point (20) of a short range rf network and a user terminal (10) of the short range rf network. The method comprises using a first short range rf transceiver (104) at the access point for access communication with a user terminal (10) for communicating information relating to establishment of a connection with the user terminal (10), and using a second short range rf transceiver (106) at the access point for user data communication for communicating user data with the user terminal.

Abstract: The invention discloses a method of sending a download status indicator 320 depicting the status of a data transfer between a sending device and a receiving device. The invention is suitable for use with short range radio communication technologies including Bluetooth short range connection technology. In an embodiment of the invention, the invention is employed within a Bluetooth information Kiosk environment. In the embodiment, a Kiosk 100 establishes a connection 300 with a plurality of handheld devices (102,103,104) using the Object Exchange (OBEX) protocol. The download status indicator is estimated, for example, by the Kiosk 100 from models generated from usage statistics collected from previous data transfers. The download status indicator and related information is sent in an Application Parameters header 310 comprising of a plurality of triplets and is updated repeatedly in subsequent Application Parameters headers.

Abstract: A method of and a system for controlling low power radio frequency activity of terminals, including a method of selecting and activating a wireless terminal. A signal, including a transmission indication, is transmitted by a first terminal. A second terminal receives the signal a number of times and compares the received transmission indications with predetermined indication values. When the comparison shows that a predetermined number of satisfactory transmission indications have been received by the second terminal, the second terminal commences transmission. The transmission indication can be messages having tail portions with a preselected set of states.

Abstract: The invention discloses a technique that enables a device lacking master-slave switch capability to establish a connection with a piconet and becoming a slave. The invention is particularly suitable for applications where a role exchange is required, such as when a requesting device attempts to access a Bluetooth LAN access gateway where the gateway needs to maintain master status and the device slave status. In an embodiment of the invention, a first device sends an inquiry (300) to a second device followed and receives identifying information of the second device. The first device pages (310) the second device using the received identifying information to establish a first connection thereby establishing the first device master of an ensuing piconet. The first device terminates (320) the first connection which signals to the second device to initiate a connection with the first device.

Abstract: A terminal device, a memory module, a method and a system for exchanging electronic content. A wireless connection is used for transferring electronic content between wireless terminals according to predetermined tailoring information. The tailoring information defines what electronic content it is possible to exchange between the wireless terminals. The memory module stores the tailoring parameters and is separate from and releasably attachable to one terminal device. That terminal device is adapted to read the tailoring information from the memory module and to transmit the tailoring information to another terminal device over the wireless connection.
