A notification apparatus includes: an obtaining unit that obtains information on a use of a first mobile communication network when a mobile communication terminal configured to use selectively one of a first identifier and a second identifier which are assigned to the first mobile communication network and the second mobile communication network, respectively so as to perform a communication currently connects to the second mobile communication network using the second identifier; and a notifying unit that notifies the information obtained by the obtaining unit to the mobile communication terminal via the second mobile communication network.

A method for setting a policy for Over-The-Top (OTT) calls in a mobile network is provided. The method includes determining whether a cell of the mobile network has at least one neighboring cell of at least one roaming partner of the mobile network, and determining a bearer policy for routing OTT calls in the cell based on whether the cell is determined to have the at least one neighboring cell of the at least one roaming partner. The determined bearer policy indicates whether the OTT calls in the cell are to be routed on a dedicated bearer or a default bearer for connecting to an Internet Access Point Name (APN).

One embodiment of the present invention provides a collect call method and system thereof, more particularly, in order to charge the called party with a uniform toll for collect call, which is determined by only the type and location of called party terminal. In one embodiment, the collect call method, system and a counsel service providing method use a free VoIP network for part of the voice call link and a charge PSTN network for the rest of the voice call link. In one embodiment, if the first link corresponding to the collect call request is established, the collect call switch calls the called party terminal to establish the second link, and billing on the second link is initiated.

The present invention discloses methods and systems for communicating at a cellular router between a first wireless communication module and a first subscriber identity module (SIM). The cellular router receives a first request from a first wireless communication module and encapsulates the first request in a first modified request. The cellular router then sends the first modified request to a first SIM card in a first communication apparatus and waits for a first modified reply. While waiting for the first modified reply the cellular router sends at least one halt message to the first wireless communication module after a first time threshold. After receiving the first modified reply, the cellular router decapsulates the first modified reply to retrieve a first reply and sends the first reply to the first wireless communication module where the first modified reply is a reply to the first modified request.

An inmate communication system and method of using are described herein for obtaining a lowest session rate. The inmate communication system includes a session boarder controller (SBC) server that analyses data from multiple carriers, historical sessions, and additional factors such as quality of service to determine a lowest rate for the session. The SBC server then routes the session using the carrier that has the determined lowest rate for the session. Further, the SBC server is configured to include both local and location redundancies to avoid interruptions in session service.

A method and a callback notification system (CNS) are provided for sending a missed call ring alert (MCRA) from a source number to a destination number. The CNS receives communication information from a calling party device (CGPD) or a network thereof, when an unsuccessful communication attempt is made by the CGPD to contact a called party device (CDPD), and places a call to the destination number with an identification of an originator of the call as the source number using the communication information. The CNS identifies a ring of the CDPD when the call successfully reaches the destination number and terminates the call before chargeable completion of the call, thereby sending an MCRA from the source number of the CGPD to the destination number of the CDPD. The CNS sends one or more alternative callback notifications to the destination number, concurrently with the MCRA or if the MCRA is unsuccessful.

Systems and methods are provided for providing differential treatment to user traffic involving optimized reporting of start and stop traffic. The systems and method can include detecting, at a user plane function, an initiation of a type of traffic being performed at the user plane function, providing, by the user plane function, a start event trigger of the type of traffic detected by the user plane function to a session management function, and receiving, at the user plane function, a policy associated with the type of traffic from the session management function, the policy including instructions preventing submissions of subsequent event triggers to the session management function until an end of the type of traffic, the subsequent event triggers being associated with the type of traffic detected by the user plane function.

A communication system includes: an information transmission section that performs information transmission via a communication network; a communication relaying section that relays a communication between a mobile communication terminal and the communication network; and a fee determination section that determines a communication fee for communication via a communication network or a monetary amount of reward for the information transmission, based on a first communication volume related to the information transmission, or on a ratio of the first communication volume to a second communication volume related to the communication relaying.

A method performed by a device for determining a subscriber identification module (SIM) card to be used for a call is provided. The method includes determining, for each of plural call types and prior to a new call originating from a user equipment (UE), a SIM card to be used, from among a first SIM card installed in the UE and a second SIM card installed in the UE, identifying a call type of the new call originating from the UE, selecting, based on the identified call type, the SIM card previously determined for the identified call type according to the determining, and updating, based on performance of the new call and prior to a subsequent call, the determined SIM card for at least one of the plural call types.

Aspects of the invention enhance the capabilities of the MaaP by adding interfaces thereto so that the platform directly interfaces with the OCS, the PCRF, the EIR, the CDB and the HSS without middle layer or without using RCS as an intermediary. Moreover, embodiments of the invention may create a user interface of the MaaP so that users may configure parameters to interact with the network nodes right from the user interface.
