Optimized information transfer associated with relocation of an ip session in a mobile communications system

Abstract: A solution for supporting relocation of an IP session of a mobile node during a network layer handover in a mobile communication system. In the method, from the application context information on the mobile node is detected a first set of capabilities of a network node that that facilitate maintaining the IP session. This first set of capabilities is queried from one or more potential next network node. Applicability of the potential next network node to the relocation of the IP session is determined by the capability information on the first set of capabilities.

All-optical packet-switched networks: a study of contention-resolution schemes in an irregular mesh network with variable-sized packets

Abstract: This paper presents a comparative study of contention-resolution schemes based on wavelength, time, and space domains in an unslotted optical packet-switched network with a large irregular mesh topology consisted of 15 nodes For the first time, to the best of our knowledge, we investigated the effect of selective deflection and limited wavelength conversion Features and performances of different combinational schemes are listed and compared While simulation results show the effectiveness of wavelength conversion for resolving contentions over optical buffering and space deflection, physical explanations of the different effectiveness in resolving contentions of these schemes are also discussed

Method and apparatus for optimizing energy consumption for wireless connectivity

Abstract: An approach is provided for optimizing energy consumption for wireless always-on connections. A radio management module buffers non-real time data and schedules the transmission of the non-real time data by a wireless device. The module also determines a communication type for carrying the non-real time data and initiates transmission of the non-real time data based on the schedule and the determined communication type.

Method and apparatus for establishing a communication group

Abstract: A method and apparatus for joining a communication group between users of wireless communication devices, comprising at least two users (302, 305) of communication devices who are members of said group and capable of communicating with each other through communication devices, and at least one communication device user (301) not belonging to said group, who is capable of communicating with at least one member (305) of the communication group through a communication device. In the method, the communication device user (301) not belonging to said group creates an apply message (308), transmits the apply message (308) wirelessly to at least one member (305) of said communication group for the purpose of becoming a member of said group, at least one member (305) of the group creates a feedback (307) on joining said group, transmits the feedback (307) wirelessly in response to the received apply message, and a decision is formed on joining said group in response to said feedback.

User interface device

Abstract: A keypad (7) of a mobile telephone handset comprises a keymat (17) beneath which are disposed capacitive sensing plates (20, 21). The keypad may be used in a conventional manner to enter alphanumeric data by pressing keys (18) or as a touch pad by sliding a finger over the surface of the keymat (17).
