The present invention refers to a gateway (MGW) in a telecommunication system (TS) enabling connections to be effectively established between various networks (N, N, N) in the telecommunication system. The gateway comprises resources from different nodes (RNC, MSC, IP, VX) of the various networks. Servers (S-S) from the networks are connected to the gateway (MGW) and co-utilize the resources, which contributes to the effective utilization of the resources. This effective utilization of the resources is supported by the resources being divided into resource groups. Specific ones of these resource groups can be utilized by solely each one of the servers. Consequently, important services such as alarm services and security services can always reach the necessary resources in the gateway. Other resource groups can be co-utilized by only a small number of the servers while additional resource groups may be co-utilized by all of the servers (S-). By division into the resource groups the resources of the nodes (RNC, MSC, IP, VX) are co-utilized without the establishing of specific significant connections having to be rejected.

Telesystem with coupling device and a method in connection therewith

The present invention relates to a coupling node (MG) for coupling of communications in a telecommunication system, comprising networks (NN) with different signal formats. The coupling node has switching and trunking functions (CPCP) corresponding to the signal formats, and telefunctions, e.g. coders/decoders (F) and echo cancellers (F), which the node can couple into a communication by means of a selector (PS). The functions are supported by printed board assemblies (CB&#x2013;CB) in magazines (SR), and the printed board assemblies have signal processors (DSP&#x2013;DSP) with access points (SAP&#x2013;SAP). The selector hunts one of the signal processors for handling one of the functions. If the processor has sufficiently free memory space in its data store and in its instruction memory and sufficient processor capacity, this processor is selected. Otherwise a new processor is hunted which is investigated in the same way.

A media stream system () processes plural media streams (), e.g., speech streams or speech channels. The system comprises plural processors (), each of which execute one or more plural types of media stream processing functions (). A switch function () routes packets of the plural media streams to a sequence of the plural processors whereby the plural types of media stream processing functions are sequentially performed relative to the packets. A packet size for the packets is chosen to minimize overhead load on at least one of the plural processors without causing undue delay for a packet awaiting processing by the at least one of the plural processors. In an example non-limiting implementation, the packet size for a packet of media information is chosen to be 160 octets, consecutive packets of a same media stream being separated by a packet repetition interval which is 20 milliseconds.

Asynchronous packet processing using media stream functions

Method and apparatus for processing data in a multi-processor environment are provided. An application chain is built including at least one application to be performed on the data. The data is received, and program information, e.g., a pointer, is added to the data for identifying a current application in the application chain to be performed on the data. The data is forwarded to an available processor in the multi-processor environment and is processed using the current application identified by the added program information. The processed data is updated with new program information identifying a next application in the application chain to be performed, if any. The processed data is forwarded to an available processor, processed, and updated repeated times until the data is processed by all applications in the application chain.

Asynchronous data samples are received from a plurality of data channels for distribution onto a plurality of data processors each having a plurality of processing-slots. The identity of a channel from which a sample is received is determined using a channel ID associated with the sample. A time-stamp is assigned to at least one sample from each respective channel. Finally, at least one time-stamped sample is assigned to a processing-slot such that the separation between the time-stamp and a nearest time-stamp of at least one sample assigned to at least one other processing-slot of each respective processor is maximized.

A gateway (MG ) interconnects telecom networks (N ,N ) of different types with different signal formats (ATM,IP). A first control unit (CC ), connected (C ) to a server, controls connection set up. A second control unit (RC ) provides telecom functions (F -F ), such as speech coder/decoder or echo extinguisher, to the connection. A third control unit (BC ) establishes connections and sets up switch functions (CP -CP ) corresponding to the different signal formats (ATM,IP). A signal format converter (CP ) converts to/from a common signal format (COM ) that the telecom functions uses. A speech request goes via the server to the first control unit (CC ), which requests telecom function (F ) by the second control unit (RC ). This returns the address (ADR ) of the telecom function to the first control unit (CC ) which sends the function address (ADR ) and the network address (ADR ) of the connection to the third control unit (BC ). This interconnects the corresponding switch function (CP ) and the telecom function (F ) after conversion to the common signal format (COM ) in the signal format converter (CP ). The first control unit (CC ) thereafter requests connection to the next node from the third control unit (BC ), which establishes and indicates the connection (C ) to the first control unit (CC ). This requests setting up of a corresponding switch function (CP ) by the third control unit (BC ), which connects together the switch function with the telecom function (F ) after reconversion of the signal format. The functions (F -F ;CP -CP ) are hardware or software. They can easily be supplemented for new network types or new telecom services.

A distributed voice mail system in a network includes a server in a control layer of the network and one or more media gateways in a connectivity layer of the network, wherein the server controls resources in the media gateways to provide distributed voice mail services.

Distributed voice mail system

A method and a buffer structure ensure a fair share of the bandwidth between point-to-point and point-to-multipoint connections with the same or different priorities. For each priority class, the buffer structure includes one queue for each physical link of restoring point-to-point cells for each priority level and one queue for point-to-multipoint cells. When a cell is to be transmitted on a link, the point-to-point and point-to-multipoint cells for this link, if any, from the highest priority class in each case are identified. If the cells belong to the same priority class, the cell stored first is transmitted.

Method and device in telecommunications system

An Asynchronous Transfer Mode (ATM) switching device (20) has ATM cells (both point-to-point and point-to-multipoint) routed therethrough to one or more physical output links (31-38). The switching device (20) includes a cell buffer memory (92) which is the sole storage area on an egress exchange terminal for all cells, including point-to-multipoint cells, regardless of to which physical output link the cell is destined. For point-to-multipoint cells, pointers to the location of the cell in the cell buffer memory (92) are stored in one or more pointer queues (114), the pointer queues (114) corresponding to physical output links over which the point-to-multipoint cells are expected to be propagated. As each physical output link is selected, the pointer in the corresponding pointer queue is used to obtain the cell from the cell buffer memory (92) for readout on the selected link.
