摘要:
A broadcast channel, such as a broadcast control channel that carries a short message service, in a GSM/EDGE or similar communication system can be extended with additional timeslots. These additional timeslots can be pointed out in a tree structure, the root of which is in the SMS broadcast channel. The extended broadcast channel can be used for broadcast-like services provided under a multimedia broadcast/multicast service.

In a digital cellular radio communication system, a base station selects a speech/channel encoding mode based on measurements of the local radio environment. The mobile station determines the selected mode by trial decoding possible modes to find the most probable mode and uses the same mode for transmission to the base station on the return link. The coding gain/loss obtained by this mode switching may be used to adjust the output power of transmitters, thereby reducing the overall interference level in the system.

Disclosed herein is a context based payment system. Electronic currency or coupons can be made dependent on context, and the context can be one of location or geography, time, date, distance, sound, or other devices. The value of the currency exists only if a pre-condition is fulfilled. For example, if the currency is location dependent, the value only exists in a defined area (currency value area). The goods or the service in the value-system are also context dependent, that is, they can only be sold or offered in a defined area (product value area). Accordingly, if the product value area and the currency value area overlap, a purchase and payment can be made.

The invention relates to user access to data sets associated with a digital map via a user terminal. According to the invention the digital map together with data indicators associated with positions on the map and providing data sets are obtained. Here each data indicator is provided with at least one priority setting. A selection of data indicators is then made for the map when it is scaled for presentation via the user terminal and divided into sectors. Each sector comprises a number of neighbouring positions and is associated with a corresponding data indicator threshold defining how many data indicators that are allowed to be presented together with this sector. The selection involves selecting data indicators according to their priority settings and limited by the corresponding data indicator threshold for being presented with each sector. Then the scaled digital map is presented via the user terminal together with the selected data indicators.

The present invention relates to a terminal client (101), a client device (100, 200, 300, 400) and a network infrastructure for enabling management of messages in a telecommunications network. According to the invention, the terminal client (101) comprises a distributed inbox client component (103) that is configured to synchronize all incoming and outgoing messages with at least one other client device (200, 300) that is associated with a user of a first client device (100). The terminal client (101) further comprises a connector component (104) configured at least as an interface between the distributed client component (103) and a network infrastructure (20) suitable for forwarding and receiving messages. With the terminal client (101) incorporating in client devices associated with a user, the user is able to experience synchronized chat in real-time and can further utilize a device independent synchronous messaging service anywhere and anytime.

摘要:
A multi-channel linear predictive analysis-by-synthesis signal encoding method determines (S1) a leading channel and encodes the leading channel as an embedded bitstream. Thereafter trailing channels are encoded as a discardable bitstream exploiting cross-correlation to the leading channel.

A multi-part fixed codebook includes both individual fixed codebooks for each channel and a shared fixed codebook. Although the shared fixed codebook is common to all channels, the channels are associated with individual lags. Furthermore, the individual fixed codebooks are associated with individual gains, and the individual lags are also associated with individual gains. The excitation from each individual fixed codebook is added to the corresponding excitation (a shared codebook vector, but individual lags and gains for each channel) from the shared fixed codebook.

A multi-channel linear predictive analysis-by-synthesis signal encoding method detects (S26, S27) inter-channel correlation and select one of several possible encoding modes (S24, S29, S30) based on the detected correlation.
