Transport of multihoming service related information between user equipment and 3GPP evolved packet core

For personalizing a smart card (SC) coupled with a communication device (CD) of a user being a subscriber of a first telecommunication network (TN) and wishing to become a subscriber of a second telecommunication network (TN), a first international identity (IMSI_) and a first authentication key (AK_) being stored in the smart card (SC), the smart card receives a message (MesP) from an application server (AS) connected to the first telecommunication network and the second telecommunication network, the message (MesN) comprising a personalization command (ComP) and an admin code (ACas), after that the application server has received a request (Req) of subscription change comprising an identifier (dMNO) of the second telecommunication network (TN) and has established a secured session with a personalization server (PS) of the second telecommunication network (TN) identified by the identifier (dMNO), and interprets the personalization command (ComP) to establish a secure session with the personalization server (PS) via the application server (AS), if the admin code (ACas) is valid. The smart card negotiates with the personalization server to agree on an second authentication key, by exchanging messages containing values derived from random secrets, receives a message (Mes) containing an second international identity (IMSI_) from the personalization server (PS), and replaces the first international identity (IMSI_) and the first authentication key (AK_) by the second international identity and the second authentication key.

Smart card personnalization with local generation of keys

A method and apparatus for personalizing a smart card (SC) in a communication device of a subscriber of a first telecommunication network (TN), who wishes to become a subscriber of a second TN, is disclosed. A first identity and authentication key (AK) are stored in the SC. A first application server (AS) in the first TN receives a request of subscription change comprising an identifier of the second TN, establishes a secured session with a second AS of the second TN, and sends a message comprising the first identity and AK to the second AS so the SC can access the second TN. The second AS sends a second message including a personalization command, admin code, second identity and second AK to the communication device, which executes the personalization command to replace the first identity and AK with the second identity and the second AK if the admin code is valid.

Remote smart card personalization without third party

An exemplary technique is provided for an initial personalization of a smart card coupled with a communication device of a user. The smart card is configured to send a first request to a home location register that authenticates the user by means of a temporary international identity and a temporary authentication key. The smart card is configured to send a second request for smart card personalization to an application server. The smart card is configured to receive a response from the application server that contains a personalization command, an admin code, an initial international identity and an initial authentication key. The smart card is configured to interpret the personalization command to delete the temporary international identity and the temporary authentication key, and to replace them with the initial international identity and the initial authentication key when the admin code is valid.

Smart card initial personalization

A smart card associated with a subscription to a first telecommunication network and coupled with a communication is personalized by an application server. The server receives a request of subscription change having an identifier of a second telecommunication network; establishes a secured session with home location register of the second telecommunication network identified by the identifier and receives a first message having a second international identity and a second authentication key from the home location register; and then sends a second message having a personalization command, an admin code, the second international identity and the second authentication key to the communication device. The smart card is able to interpret the personalization command to delete the first international identity and the first authentication key and replace them by the second international identity and the second authentication key if the admin code is valid.

The invention proposes in particular a network service PDP manager device () sending virtual private network configuration information using the COPS-PR protocol. The information comes from a dedicated PIB database and is sent to an edge router (to). The invention speeds up recognition of a virtual private network modification and prevents failures due to a lack of configuration information at the router. The invention also relates to a router (to), a system using the manager device and the router, and a virtual private network management method.

Network service manager device using the COPS protocol to configure a virtual private network

A method and system for initial personalization of a smart card coupled with a communication device of a user who is not yet a subscriber of any telecommunication network are disclosed. A temporary international identity and a temporary authentication key are stored in the smart card and in a home location register connected to a roaming entity of a telecommunication network. A series of signals are exchanged between the smart card, the roaming entity, an application server and a personalization server to establish a secure session between the smart card and the personalization server. During the secure session, the smart card receives a message containing an initial international identity from the personalization server, and replaces the temporary international identity and the temporary authentication key by the initial international identity and the initial authentication key.

A method for reserving resources in a packet communication network, preferably an IP protocol network. The method includes sending an active packet containing a request for reservation of resources for an active data flow, receiving the packet by an active node in the network, and reserving resources of the node according to the request. In this method, an active packet communication network node, in particular an IP active router, reserves resources for processing data of an active data flow according to a resource reservation request for this active data flow contained in this active packet received by the node.

An access control gateway (E) for controlling access to a first data network (D), which gateway includes a filter for filtering data coming from a second data network. The filter is adapted to decide whether to transmit the data to the first network as a function of information contained in the data relating to the processing of the data by active routing systems of the first network.
