A solution making it possible for one telecommunication network operator (') to act as intermediate distributor or administrator of a content provider () for a multitude of operators () is presented. The content provider () has a single relation to the central operator (&#x2032;), in turn having relations to other operators (). It is thus possible for the content provider () to reach all users () of all operators () through a single relation to that operator (&#x2032;). The content provider () provides service content, e.g. media content. A list of targeted users () or subscribers is compiled. The central operator (&#x2032;) collects necessary subscriber attributes (), such as position, device information and access properties, from the other operators (). The content is modified according to the collected attributes (), and the content is distributed to the subscribers () in the best possible way.

Multi-operator telecommunication distribution of service content

A system, comprising various methods and apparatus providing a transparent communication session setup and control for communication sessions involving different communication capabilities, is disclosed. The system receives a request for a communication session at a proxy apparatus, the request being originated from a first subscriber to the communication session using a first group of terminals. The system identifies at least a second subscriber to the communication session using a second group of terminals. The system evaluates types of communication being available for the first group of terminals and at least the second group of terminals on the basis of the request. The system sets up terminal sub-sessions from the proxy apparatus to the first group of terminals and to at least the second group of terminals according to types of communication being available for the first group of terminals and at least the second group of terminals.

Proxy apparatus and method

A system and method for routing an incoming telephone call to a mobile terminal () which is a combined cordless phone and mobile phone. The call will be connected over either a fixed network () or a mobile network () depending on whether the mobile terminal is within or out of radio coverage of a home base station () connected to the fixed network. The call is routed in response to a routing indication which is included in the called number of the mobile terminal depending on the location of the mobile terminal. In this way, network operators may direct calls over the fixed network in preference to the mobile network, thereby relieving the mobile network. A single telephone number can also be used for the combined cordless phone and mobile phone.

System and method for providing telecommunication services

A method and system for communicating information includes evaluation regarding routing of calls performed at a call control point in an ITSP and/or wireless network. A PIC identity associated with another party's preferences is acquired and sent to the call control point. The PIC identity identifies the type of the carrier network (e.g., circuit switched or VoIP) and is used to make further routing decisions. If a circuit-switched carrier is identified, the IP homing leg is terminated at the voice gateway in the recipient's HPLMN and information is sent over to the GMSC where normal, circuit-switched routing procedures. If a VoIP carrier is identified then the called user's roaming number is retrieved from the HLR, and the call is further routed directly over the IP domain towards a voice gateway at the visited network minimizing the number of transcodings. Additional transcoding steps can be avoided if a single encoding is agreed upon according to 'tandem free operation' (TFO). Combining inband signaling through the telephony exchanges and out-of-band signaling in the IP network it is possible to achieve, for a mobile subscriber, one encoding and one decoding of a voice.

Methods and systems for call routing and codec negotiation in hybrid voice/data/internet/wireless systems

In a cellular mobile communications network, routing decisions pertaining to supplementary services are made by a home location register (HLR). For calling subscriber supplementary services, such as private numbering plans, a mobile services switching center (MSC) requests that the HLR perform the necessary routing decisions, and the HLR responds accordingly. For called subscriber supplementary services, such as call forwarding on busy, the MSC sends status information (such as the busy condition) to the HLR, and the HLR responds by determining supplementary call routing information, which is then sent to the MSC. Determining the supplementary call routing information may require that the HLR select from among several routing alternatives, in dependence on a condition such as time-of-day. In an alternative embodiment of called subscriber services, the HLR may recognize, upon initially being asked for a roaming number for a called subscriber, that a called subscriber condition exists that requires making a choice from among several possible routings. The HLR may solicit choice-determinative information from the MSC, which in turn prompts the calling subscriber for this information. The requested information may be returned to the MSC from the calling subscriber in the form of a dual tone multi-frequency (DTMF) signal. The MSC may convert the DTMF signal into a message containing the requested information, for transmission to the HLR.
