The invention is concerned with transmission of speech information over mixed networks, particularly over a segment using packet transmission in an otherwise circuit switched data transmission network. According to the invention, PCM transmission lines are connected with a packet based network such as an IP network in such a way, that data from one or more channels of a first PCM transmission line is collected in the payload part of a data packet. Further, the destination address of the data packet is constructed in such a way, that the packet network entity being connected to the second PCM transmission line can determine based on the destination address of the packet, to which channel or channels of the second PCM transmission line the data should be transmitted.

Data transmission method and a network element

When an ad hoc network is formed between short range wireless devices, at least one device assumes the role of an ad hoc network information provider for the new piconet. In this role, the device allocates a browsing hierarchy of service classes in its service registry. The service classes will provide a record to characterize the ad hoc network. When a new wireless device arrives within the communication range of any member of the ad hoc network, its inquiry signals are answered by the first member detecting the inquiry. If that first member is an ad hoc network information provider, it responds with information accessed from its service registry characterizing the ad hoc network. If, instead, an ordinary device in the ad hoc network is the first to respond to the inquiry signals of the arriving device, the device responds with the address of the ad hoc network information provider. The arriving device then pages the ad hoc network information provider to obtain information characterizing the ad hoc network.

Ad hoc network discovery menu

A clientmay be authenticated by transmitting or beaming a telecommunication network subscriber's authentication to the client from a device, over a wireless link. For example, a GSM telephonemay authenticate an electronic bookto a content providing service within the Internet. The service verifies the authentication using the subscriber's GSM network operator's Authentication Centerto generate an authenticator and the client correspondingly generates a local copy of the authenticator using a GSM SIM over the wireless local link. The authentication is then determined by checking that these authenticators match and thereafter the authenticator can be used as a session key to encrypt data in the service.

Authentication in data communication

A system and method is disclosed to enable a mobile phone or wireless PDA to discover Internet businesses and services by accessing the Universal Description, Discovery and Integration (UDDI) registry using a user's location or coordinates. The method facilitates the formation of a query to the UDDI registry for the wireless device user. The method obtains a location for the user. The method constructs a personal user profile of the user's UDDI searching strategies, locations and Internet accessing preferences. The user profile can be used as a shortcut for online or offline queries to the UDDI registry or for accessing pages from web sites, or updating location information in response to the user's entry of abbreviated inputs to the wireless device. The method is embodied as programmed instructions which may be executed within the user's wireless device to query the UDDI registry. Alternately, method is embodied as programmed instructions which may be executed within a separate knowledge engine server to query the UDDI registry in response to commands (from the user's wireless device. The server can be used to cache files accessed from web sites, for selective forwarding to the user's wireless device.

Service discovery access to user location

A network element of a telephone network and method for monitoring connections and receiving data from an incoming leg of a connection and forwarding the data to an outgoing leg of a connection, wherein when the network element observes that both the incoming and outgoing legs of a connection are transmitted via a packet data network to a previous or correspondingly the next element of the telephone network, a release of the previous network element occurs, and an indication of a packet network address corresponding to the next telephone network element is made. The previous network element may then transmit data via the packet data network directly to the next telephone network element.

Call setup method

Device name conflicts are resolved when adding devices to existing ad hoc networks or when joining two ad hoc networks together. After a connection has been established between a new device to be added and a first member device in the ad hoc network, a name distribution message is transferred by the new device to the first member device. The name distribution message will be passed from member device to member device in the ad hoc network, and at each member device a name conflict check is performed. Device name conflicts are also resolved when joining two ad hoc networks together. The contents of name manager tables of the two respective ad hoc networks must be exchanged. This is accomplished by forming a name distribution message for each name record in the name manager tables of the two devices establishing the connection on behalf of their respective ad hoc networks. Then the name distribution messages formed in each respective ad hoc network are distributed to the other ad hoc network. In the process of distributing the name distribution messages through the other network, any name conflicts are commonly resolved in all of the devices in both ad hoc networks.

Naming distribution method for ad hoc networks

The invention relates to telecommunication networks and particularly to mobile networks using Asynchronous Transfer Mode (ATM) transmission systems. The invention also relates to the control of mobility and call control functions in ATM systems. According to the invention, a network element (MSC/BSC) of a telecommunication network, such as a mobile network, which in a conventional telecommunication network architecture ensures the switching of circuit-switched connections, is provided with an ATM switching function. ATM switching functions are controlled with the same call and switching control operations ( ) that are conventionally used e.g. for the control of a TDM switching field ( ) in a PLMN network element. In a minimum implementation, an ATM switching field ( ) provided with a suitable control interface ( ) is simply arranged in place of or parallel with the TDM switching field. The switching network element thus becomes an ATM network node of a physical or a logical interface layer. PLMN level signalling, mobility management and call control are implemented using solutions offered by existing mobile networks and current PLMN network elements.

Mobile networks using ATM switching

Speech is transmitted between a base station (BTS) and a TRAU by converting a speech signal into a parameter group which is inserted in a traffic frame which is transmitted as a packet comprising a header and a payload. In accordance with the invention, the payload is formed of the contents of several traffic frames until the payload is essentially full, and a packet is sent to the destination via the transmission network. At the destination the traffic frames are separated from the payload of the received packets and they are passed to a speech decoder. The packing of packets full can be started about a second after the beginning of the connection and after pauses, in which case the ending of a pause is transmitted to the listener as fast as possible.

Speech transmission in a packet network

A method and an equipment for packet prioritization when routing data packets is presented. Several priority classes are defined for the packets, and a first threshold value and a second, higher, threshold value is defined for each prioity class. In association with each packet, the oldest packet of a given prioritiy class is selected, and if the packet is older than the second threshold value of the priority class concerned, the packet is discarded, and the next priority class is selected. If the packet is older than the first threshold value of the priority class concerned, at least one packet of this priority class is transmitted until the oldest packet in the priority class is younger than the first threshold value of the priority class concerned, whereupon the next priority class is selected.
