  • Publication number: 20190199760
    Abstract: Methods and apparatus for addressing of Virtual Network Functions, VNFs. A registration controller of a VNF instance controls a transmitter to transmit a registration request to a VNF Service Registry, VNF-SR, the registration request identifying a public address of the VNF instance. A receiver of the VNF-SR receives the registration request and a VNF address determiner determines a VNF address for the VNF instance based on the received registration request. A Database Management System, DBMS, stores the determined VNF address in a memory. An event subscriber of a Virtual Network Function Manager, VNFM, controls a transmitter to transmit a subscription request to the VNF-SR, the subscription request comprising an identifier for a VNF. A receiver of a Virtual Configuration Server, VCS, receives a notification from the VNF-SR when a change has occurred in configuration and/or address data stored in the memory of the VNF-SR and relating to one or more VNF instances.

  • Patent number: 8582563
    Abstract: The present invention is aimed to provide a more flexible data structure where any IMPU, even those of the SIP URI type, may be shared by more than one IRS in order to simplify the registration of an IMPU for users of a Fixed-Mobile Convergent network. To this end, there is provided a flexible data structure wherein a number n of IMPUs of a user may be distributed in a number m of Implicit Registration Sets, wherein a given IMPU may be shared by more than one IRS, each IRS is associated with an access condition, and the explicit registration of said given IMPU under a given access condition triggers the implicit registration of those IMPUs in the IRS associated with said access condition, while the registration status of IMPUs in any other IRS remain unchanged.

  • Publication number: 20110310884
    Abstract: The present invention provides a mechanism whereby a session established at a particular MGCF between a subscriber of a legacy network and a first user of a referral service can be replaced by another session to be established between the subscriber of the legacy network and a second user of the referral service without disturbing the sessions already established. Therefore, the present invention provides a new method and devices for generating an IMS Telephony Endpoint, which includes a first information field with a telephony Universal Resource Identifier identifying an originating or destination subscriber, as the case may be, and a second information field with information usable to identify the generating MGCF as the particular MGCF holding a session for such served subscriber. Such ITE is submitted towards the IMS and is included in a further referral service request involving such session so that the particular MGCF may be identified.

  • Publication number: 20080215736
    Abstract: A method, apparatus, and application server for dynamically allocating an application server within an IP Multimedia Subsystem (IMS). A Serving Call/Session Control Function (S-CSCF) receives a user request and queries a central database to determine whether the user is allocated to an application server. If so, the S-CSCF forwards the request to the allocated application server. If the user is not already allocated to a server, the S-CSCF allocates the user to an application server and forwards the request to the newly allocated application server. The S-CSCF or the newly allocated application server sends a request to the central database to record the allocation.

  • Publication number: 20060174015
    Abstract: A telecommunications system includes a public network, to which a first endpoint device is connected, and a data network, to which second endpoint devices and a multimedia controller are connected. The networks are interconnected via a remote access server which provides data connectivity for the first endpoint device but which has a limited bandwidth. Codecs with corresponding bandwidth are selected for communication between the endpoints. The multimedia controller receives a communication request that comprises information related to the codecs desired by the endpoint device for said communication. The multimedia controller sends an address detection message towards the endpoint device involved in said communication and checks the address information in the answer to said address detection message. Final codecs for the communication are selected depending on if the answer contains an address of a network element, which can limit the bandwidth for said communication.
