Method for delivering dynamic policy rules to an end user, according on his/her account balance and service subscription level, in a telecommunication network

A method for delivering dynamic policy rules for an end user of a communication service during a communication session is provided. The method includes receiving subscription information at a Policy and Charging Rules Function (PCRF) in order to determine an initial policy; applying the initial rules via a Policy and Charging Enforcement Function (PCEF); triggering an Extended Online Charging System (EOCS) for the user's service/network resource usage; rating and charging the user via the EOCS in real time; triggering a change of policy in a change notification from the EOCS to the PCRF; determining new rules for the new policy at the PRCF; receiving the new rules and applying them at the PCEF.

Server-side trick mode restrictions in a stream may be provided. The stream may comprise, for example, a Video on Demand (VOD) Adaptive Bitrate (ABR) stream. First, a playlist request corresponding to a stream may be received from a user device. Next, a current stream position in the stream may be determined. In response to receiving the playlist request and when the current stream position corresponds to a non-skip segment, a playlist may be created having a last chunk comprising a next chunk of the stream from the current stream position. The playlist may then be provided to the user device.

Real-time interstitial content resolution and trick mode restrictions

A first manifest request may be received and, in response, a first manifest may be requested. Next, at least one interstitial content insertion source may be queried based on the first manifest and, in response to querying the interstitial content insertion source, interstitial content details may be retrieved from the at least one interstitial content insertion source. Then it may be determined that a version of interstitial content corresponding to the interstitial content details does not exist in a service provider back end at same bitrates as content corresponding to the first manifest. Next, local ingest and encoding of the interstitial content to the service provider back end may then be triggered in response to determining that the version of interstitial content corresponding to the interstitial content details does not exist in the service provider back end at the same bitrates as the content corresponding to the first manifest.

Server-side interstitial content insertion

In order to manage a change in conditions of using a service associated with a communication in progress established by a user terminal (TU) within its communications network (RT), a server determines that the user's account does not permit the delivery of the service with a change in the conditions of using a service, after the receipt of a first request derived from a network element, said request comprising an identifier of the service regarding the communication and a parameter defining the change in conditions of using the service, and the server transmits to the network element a response containing a code indicating that the delivery of the service is authorized only with other conditions of using the service, in order for the network element to transmit to the server a second request containing another parameter defining another change in conditions of using the service.

Method of setting up a communication session between a calling client (C) and a called client (C), through a communication network (SN, SN, SN) containing at least one address translation device (NAT, NAT). This method contains stages for the transmission of signaling messages (fs), passing through at least one address translation device and allowing the exchange of the physical addresses of the clients. At least one of the clients implements a solution for the traversing of address translation devices. The method is innovative in that at least one client adds, within the sent signaling messages, a parameter representing the implementation of the traversing solution and that, in the presence of such a parameter, the network devices do not implement their own solutions for the traversing of address translation devices.

Traversing of NAT address translation equipment for signaling messages compliant with SIP protocol

A signaling server (SS) comprising means for transmitting SIP signaling messages with a client (T) through a NAT address translation device temporarily binding a public address to the client's private address, including means for receiving registration messages from the client and for sending the client a validity duration, at the end of which it must transmit a new registration message. The invention resides in the fact that if the client is located behind an address translation device, it determines an approximate expiry time for the temporary binding by successively sending test messages after an increasing wait time until the termination of the binding is detected. This approximate time is then used by being transmitted as the SIP validity period.

Learning the expiry time of an address binding within an address translation device for an SIP signaling server

A mobile communication terminal (T) comprising connection means (M) for connecting to access networks (N, N) and registration means (M) for periodically transmitting registration messages to a signaling server (SS) located within a public communication network (PUB) connected to these access networks. It is characterized by a memory (M) capable of associating a validity period with at least some of the access networks, and in that the registration means (M) are provided for transmitting registration messages with a periodicity equal to the validity period associated with the access network (N, N) to which the terminal (T) is connected.

Optimizing the connection between a mobile communication terminal and a signaling server through an address translation device

Method of setting up a communication session (fm) between a calling communication client (C) and a called communication client (C), through a communication network (SN, SN, SN) comprising at least one address translation equipment (NAT, NAT). It comprises steps for transmission of signal messages (fs), transiting through address translation equipment and enabling interchange of physical addresses of communication clients to set up the communication session. This method is characterized in that at least one client transmits at least one signal message containing a physical address in a first location, and coded information containing this particular physical address in a distinct second location.

Network address translation (NAT) traversal equipment for signal messages conforming to the SIP protocol by redundancy of address information

The invention relates to an inter-domain router, for an Internet Protocol communications network, including a processing module to generate as a function of routing data outgoing messages intended for other routers which comprise information data representative of routes for routing IP datagrams and a control module to analyze at least some of the routing data, in order to define route aggregates as a function of selected configuration information, and for delivering output data representative of the route aggregates, so that the processing module can generate outgoing messages including information data representative of the route aggregates.

A routing information management device for a router of a communication network comprises a first routing information base fed with routing information contained in routing protocol messages, a second forwarding information base having a maximum number of entries, and management means that compare at selected times the number of entries in the first routing information base relating to sending to a selected threshold less than or equal to the maximum number of entries in the second forwarding information base so as to feed the second forwarding information base with routing information selected as a function of the result of the comparison.

Device for use in a communication network router to select routing information

A distributed, multistage agent for monitoring, diagnosis and maintenance of network devices comprises an input/output interface for receiving input monitoring and diagnostic data relevant to operation of a first neighboring agent and transmitting output monitoring and diagnostic data relevant to operation of the host network device to a second neighboring agent. An agent process analyzes the input data and generates processed data characterizing operation of the host network device, using a local database which stores expected performance data on operation of said network device. The processed data is correlated with the expected data any error is signaled to the network operator. The agents may be designed as a multiple stage process, the stages being triggered by the data output by an earlier stage only when needed.
