A method for exchanging data with a mobile communication network using a group of cloned subscriber identity modules includes: receiving, by the mobile communication network, a first attachment request from a user equipment and/or machine type communication (MTC) device corresponding to a second cloned subscriber identity module; rejecting, by the mobile communication network, the first attachment request based on a user equipment and/or MTC device corresponding to a first cloned subscriber identity module still being attached to the mobile communication network, and transmitting, by the mobile communication network, a waiting time information indicative of a waiting time interval to the user equipment and/or MTC device corresponding to the second cloned subscriber identity module; and receiving, by the mobile communication network, a second attachment request from the user equipment and/or MTC device corresponding to the second cloned subscriber identity module after the waiting time interval has elapsed.

Method and system for exchanging data with a mobile communication network using at least one group of cloned subscriber identity modules

An application server for managing communications towards a set of user entities, the set of user entities having a first user entity. The application server includes a receiver for receiving a first session initiation request, the first session initiation request having a public identification identifying the set of user entities, a processor for assigning a first user identification to the public identification, the user identification identifying the first user entity, and a transmitter for transmitting a second session initiation request to establish a communication link towards the first user entity, the second session initiation request including the first user identification.

Application server for managing communications towards a set of user entities

A network entity for managing Session Initiation Protocol (SIP) communications towards a user entity in a communication network. The network entity has a receiver and a processor. The receiver is configured to receive a first SIP message. The processor is configured to generate a second SIP message in response to receiving the first SIP message, the second SIP message having user-specific data relating to the user entity.

Network entity and method for managing Session Initiation Protocol communications towards a user entity in a communication network

A network entity for registering a user entity with a first communication network, wherein the user entity and the network entity providing access to the first communication network are registered with a second communication network. The network entity has a transceiver for transferring at least one registration message for registering said user entity with the first communication network between the user entity and the network entity over the second communication network.
