  • Patent number: 9537960
    Abstract: A solution making it possible for one telecommunication network operator (10?) to act as intermediate distributor or administrator of a content provider (60) for a multitude of operators (20) is presented. The content provider (60) has a single relation to the central operator (10?), in turn having relations to other operators (20). It is thus possible for the content provider (60) to reach all users (30) of all operators (10?, 20) through a single relation to that operator (10?). The content provider (60) provides service content, e.g. media content. A list of targeted users (30) or subscribers is compiled. The central operator (10?) collects necessary subscriber attributes (80), such as position, device information and access properties, from the other operators (20). The content is modified according to the collected attributes (80), and the content is distributed to the subscribers (30) in the best possible way.

  • Patent number: 9369430
    Abstract: The present invention relates to a method and an arrangement for allowing private domains in the IMS, which makes it possible to use a SIP URI like ID@private-domain.TLD. This is achieved by providing an administration support and an interface to the IMS interconnect DNS and the DNS system of the operator network. The identity associated with private domain is established as a Private domain name based IMPU. The private domain name based IMPU and the Operator domain name based IMPU is associated by using the implicit registered identity set provided by the IMS.

  • Publication number: 20120096560
    Abstract: In a method of enabling Digital Rights Management (DRM) of content in a communications network supporting a DRM system a first user equipment (RMUE), is registering with a first rights issuer of the DRM system from which a delegation assertion, authorizing the RMUE to become a private rights issuer, is retrieved. RMUE retrieves a first, signed rights object from the first rights issuer, that contains a first set of rights for the RMUE to DRM protect private content and to issue at least one second rights object, associated with the private content. DRM protection is then applied on private content, obtained by the RMUE, according to at least the first set of rights. RMUE issues a second rights object, defining a second set of rights for rendering the private content, according to the first set of rights.

  • Patent number: 7944880
    Abstract: A method and arrangement for establishing a packet-switched multimedia session for a mobile terminal connected to a mobile access network. A first Radio Access Bearer RAB is obtained, and the multimedia session is started by communicating media over the first RAB. Simultaneously with the media communication, a quality of communicated media is monitored and evaluated. If the monitored quality is deemed unacceptable, a media-adapted second RAB is obtained, and the session is continued over the second RAB. Thereby, it is not necessary to delay the communication of media by waiting for the second RAB to be obtained.

  • Publication number: 20100111272
    Abstract: A broker node is provided, acting as an intermediate administrator for all operators during service content distribution. A content provider has a single relation to the broker. This broker has in turn relations to a number of other operators. The content provider provides the communication content. A list of targeted users or subscribers is compiled by the broker. Preferably, the broker collects necessary subscriber attributes, such as position, device information and access properties, from the other operators. The communication content is preferably modified according to the collected attributes and the content can subsequently be delivered to the subscribers in a best possible way. The broker collects payment from the subscribers and reimburses the media content supplier. In a first aspect, the broker is a distributor and payment administrator for service content. In another aspect, the broker is a mediator of use of inter-operator relations to a third-party content provider.

  • Publication number: 20100023417
    Abstract: A method and arrangement for providing security when an IMS client purchases content from a content or service provider, the IMS client having a unique IMS identity registered with a first IMS operator. A second IMS operator assigns a unique IMS identity to the content or service provider which is authenticated based on the assigned IMS identity. The validity of the IMS client is then verified towards the content or service provider, based on a mutual interconnect agreement between the first and second IMS operators, in response to a purchase request from the IMS client. The content or service provider can then also be validated towards the IMS client.

  • Patent number: 7043248
    Abstract: A system and method for routing an incoming telephone call to a mobile terminal (106) which is a combined cordless phone and mobile phone. The call will be connected over either a fixed network (104) or a mobile network (102) depending on whether the mobile terminal is within or out of radio coverage of a home base station (110) 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.

  • Patent number: 6154647
    Abstract: A telecommunications system is disclosed for extending the range of at least two service networks having different specified signalling standards. The telecommunications system includes a radio-based access network which includes at least one port to each service network. The ports are connected to at least one base station in the access network. The access network also includes a radio-based access network part capable of connecting the base station to a radio unit in the access network. The radio unit is registered in one of the service networks, the so-called home network of the radio unit, and a signal carrier in the access network has a first terminal point in the radio unit and a second terminal point in a port which connects the access network with the home network. The port functions to combine the signal carrier in the access network with a signal carrier in the home network.

  • Patent number: 6122263
    Abstract: A method and system are disclosed for use with a mobile radio network, which receives and analyzes packets from a packet-switched fixed network, such as the Internet, and depending on the type of information received (e.g., speech, low speed data, or high speed WWW data), routes the information over an appropriate radio air interface to a mobile radio terminal. The speech information can be routed to mobile radio terminals over a conventional circuit-switched mobile radio link (e.g., a GSM traffic channel), the low speed data can be routed over a packet-switched mobile radio link (e.g., a GPRS traffic data channel), and the high speed data can be routed over a wideband broadcast radio link (e.g., a DAB network radio link). As a result, mobile radio terminals can advantageously enjoy full access to the Internet and thereby communicate effectively over the Internet with other mobile and wire-bound terminals.

  • Patent number: 5761619
    Abstract: A cellular telecommunications system has a plurality of nodes, each for performing at least one of a number of cellular telecommunications system functions, including base station, speech coder, control processing, signal processing, local handoff, location register, and network interface functions. The nodes are interconnected by a network preferably comprising an optical fiber cable. In one aspect of the invention, the protocol that is used on the network is a high speed synchronous protocol, such as the DTM protocol. A first node in the system may be an antenna; an RF component coupled to the antenna; an analog-to-digital converter having an analog port and a digital port, the analog port being coupled to the RF component; and an optical fiber modem for connecting the digital port of the analog-to-digital converter to the network means. A second node in the system may be for performing base station controller functions, wherein the first and second nodes, together, operate as a distributed base station.
