Data transmission at sea

Abstract: By means of the present solution, a wireless data transmission is enabled between a ship (L) sailing at sea and an on-land telecommunications network (N). The solution involves utilizing a microwave radio link between the ship and an on-land base station (BS1, BS2, BS3, BS4). The network (N) maintains information of the ship route (R) such that the base station (BS1, BS2, BS3, BS4) knows when a ship (L) is approaching its area (CA1, CA2, CA3, CA4). Accordingly, the ship (L) knows which base station (BS1, BS2, BS3, BS4) it is approaching. The accurate transmission direction is determined by means of a gyroscope and the GPS location of the ship (L).

Apparatus and a method for selecting a frequency band in a mobile communication system

Abstract: The invention relates to a method and apparatus. In the method, an apparatus, for example, a base station, receives radio interface capabilities from a mobile node. The apparatus receives a subscriber frequency band priority profile identifier from a mobility management entity node. The apparatus finds an entry from a frequency band priority data structure using the subscriber frequency band priority profile identifier and the at least one radio interface capability and obtaining at least one frequency band priority from the entry. The apparatus applies the at least one frequency band priority to control the mobility of the mobile node.

CASCOM: context-aware service co-ordination in mobile p2p environments

Abstract: The research project CASCOM (Context-aware Business Application Service Co-ordination in Mobile Computing Environments) will implement, validate, and trial value-added support for business services for mobile workers and users across mobile and fixed networks. The vision of the CASCOM approach is that ubiquitous application services are flexibly co-ordinated and pervasively provided to the mobile users by intelligent agents in dynamically changing contexts of open, large-scale, pervasive environments.

Portability of a subscriber id

Abstract: A name server (DNS-A) of a first telecommunications network (CN-A) receives a query (2-5) containing or expressing a first form (e.g. E.164) of a subscriber ID, and replies to the query by informing a subscriber ID of a second form (e.g. SIP-URL) (2-7). The name server (DNS-A) detects that the subscriber ID relates to the subscriber who has been a subscriber of the first network (CN-A) but has become the subscriber of a second network (CN-B), and that the query was sent from a third telecommunications network (CN-C). The name server (DNS-A) starts a process which results in at least the domain address of the second network (CN-B) being transmitted to the sender (DNS-C, SIPS-C) of the query. In this way, traffic (2-10) can be transmitted directly between the third telecommunications network (CN-C) and the second telecommunications network (CN-B).

Procedure for accessing a service in a data communication system, and a data communication system

Abstract: The invention relates to a procedure and a data communication system in which a service provider gives the user of a service a set of expendable passwords that the user can use to access the service via a telecommunication and/or data network. The system comprises a user's terminal device provided with means for sending a password at log-on to the service, and a server to which the terminal device sets up a connection and which comprises means for identifying the password and for allowing/denying access to the service on the basis of the password supplied. The terminal device comprises means for storing a set of passwords and for selecting the right password from the stored set of passwords at log-on to a predetermined service to allow automatic addition of the password to a connection setup signal to be transmitted from the terminal device to the server.
