Abstract: A method is proposed of provisioning connectivity service data for a device when the device attaches to a telecommunications network. The connectivity service data comprises information required to enable connectivity between the device and at least one further device of the network. Dynamic data relating to the device is obtained as part of one of the device attaching to the telecommunications network and a previous attachment of the device to the network. The dynamic data is of a type that may change from one such attachment to another such attachment of the same device. The connectivity service data is then selected based on the obtained dynamic data. It is then arranged for the selected connectivity service data to be provisioned to the device.

Abstract: The present invention relates to a communication system (SYS), a gateway apparatus (HiGA) and a method for allowing services of a first type provided by a communication server (IMS-S) to be provided to terminal devices (T1, T2, . . . Tn . . . TN) of a home network (CPN) independent of whether the terminal devices are of a first type or a second type (IMS-based or non-IMS-based). The gateway apparatus (HiGA) comprises one or more service-specific mapping applications (AS) for adapting the control plane (SIP) used between the second type terminal devices (T2) to the control plane (HTTP) used between the gateway apparatus (HiGA) and the communication server (IMS-S).

Abstract: A first signal representation of one or more of the multiple channels is encoded in a first encoding process, and a second signal representation of one or more of the multiple channels is encoded in a second, filter-based encoding process. Filter smoothing can be used to reduce the effects of coding artifacts. However, conventional filter smoothing generally leads to a rather large performance reduction and is therefore not widely used. It has been recognized that coding artifacts are perceived as more annoying than temporary reduction in stereo width, and that they are especially annoying when the coding filter provides a poor estimate of the target signal; the poorer the estimate, the more disturbing artifacts. Therefore, signal-adaptive filter smoothing is introduced in the second encoding process or a corresponding decoding process.

Abstract: A method and apparatus for performing a service negotiation between a mobile terminal and a server offering mobile services. A service request is received from the mobile terminal including a list of requested services, which is compared with a set of available services that the server can provide. It is then determined which services that were requested but are not available and cannot be provided by the server. A delta list is finally transmitted to the mobile terminal comprising the services not available, such that the mobile terminal can determine which services that can be used. A pre-defined tree structure is preferably used for specifying services in the service request and delta lists such that a single root node specifies all services in nodes subordinated to the root node. In this way, the amount of exchanged information and processing in the mobile terminal are reduced.

Abstract: A node (22) of a telecommunications network (2) receives, over a transmission chain (24) subject to packet jitter, packets of a connection involving a client device (26). The node (22) comprises a packet buffer (38) configured to store the packets received over the transmission chain prior to transmission of the packets to the client device (26). The node (22) further comprises a client-conscious scheduler (40) which is configured to schedule the transmission of the packets from the packet buffer (38) over a channel (32) to the client device (26) in accordance with a timing consideration of the client device (26). In an example embodiment, the timing consideration of the client device (26) which is taken into account by the scheduler (40) is avoidance of drain of a playout buffer of the client device.

Abstract: Data is multiplexed in a frame having a fixed bit length in a telecommunication system. The data is transmitted by transmitting a first transport channel comprising a first number of bits; transmitting first error detection bits associated with the first transport channel and comprising a second number of bits; transmitting a second transport channel comprising a third number of bits; transmitting a third transport channel comprising a fourth number of bits; and selectively transmitting a control channel comprising a fifth number of bits. The control channel is transmitted after the first error detection bits and before transmission of the third transport channel. Whenever the control channel is transmitted as part of the frame, a sum of the first, second, third, fourth and fifth number of bits equals the fixed bit length, but whenever the control channel is not transmitted as part of the frame, a sum of the first, second, third and fourth number of bits equals the fixed bit length.

Abstract: Recently, interference rejection combining techniques have been proposed which can significantly increase the performance of the uplink in C/I limited environments. However, as with many signal processing techniques, calculation complexity can be performance issue. Thus, according to exemplary embodiments of the present invention, the noise cross-correlation matrix used in interference rejection combining is reduced by applying beamforming and signal combining techniques. In this way, the benefits of interference rejection combining are obtained while reducing the processing complexity and freeing processor resources for other activities.

Abstract: A method and an arrangement of functional entities in a mobile telecommunications system for supporting to a mobile subscriber a second set of operator specific services (OSS+), having a high level of functionality, additional to services standardized in the system. A first set of operator specific services (OSS), with a lower level of functionality, is supposed to already be provided for in the system. The second set of services (OSS+) is provided for by a telecommunications standard different from the standard which provides the first set of services (OSS) and is preferably a structured standard for mobile telecommunication. The second set of services (OSS+) is triggered by an intelligent network capability indicator, that is included in a subscription information field stored for each subscriber in a subscriber database.

Abstract: The invention relates to a device and a method for switching optical wavelength channels. Said optical wavelength channels are introduced into at least one access waveguide provided on a first side of a first multi-mode waveguide (10). Subsequently, the wavelength channels are transmitted through said multi-mode waveguide (10) and projected on at least two connection waveguides provided on the opposite side. Subsequently, the optical wavelength channels are transmitted through the connection waveguides. For each wavelength selective cross-connection structure (2, 4, 6, 8) the phase is changed for a reflecting wavelength of two phase control elements (C1, C2, D1, D2, E1, E2, F1, F2) arranged in a first and a second connection waveguide on a first side of said wavelength selective cross-connection structure (2, 4, 6, 8), simultaneously as at a second side of said wavelength selective cross-connection structure (2, 4, 6, 8) said reflecting wavelength phase remains relatively unchanged.

Abstract: A self-configuring node includes a number of data processors associated with corresponding ports of an asynchronous transfer mode (ATM) switch. When the node is placed into service, each of the processors automatically broadcasts an initial message to all of the ATM switch ports including each processor's identification and ATM switch port location. After receiving the initial message broadcast by the processor, a designated master processor stores the broadcasting processor's identification and ATM switch port location in a database and sends an acknowledgment directed specifically to the processor broadcasting the initial message. From that received acknowledgment signal, the processor recognizes the identity and ATM switch location of the master processor. Internal Control Paths (ICPs) are established through the ATM switch between processors using the identification and location information stored for each board processor.
