A charging server stores records corresponding to each of multiple subscriber identifiers associated with respective mobile devices. At least one record contains a counter value corresponding to one of multiple counter identifiers. The charging server receives a request from a policy server via a network, containing one of the subscriber identifirs and a session identifier. Responsive to receiving the request, the charging server determines whether the request includes any counter identifiers. When the request does not include any counter identifiers, the charging server determines whether the record corresponding to the received subscriber identifier contains any counter values. When the record includes at least one counter value, the charging server establishes a communications session with the policy server and transmits the at least one counter value to the policy server. When the record does not include any counter values, the charging server establishes a communications session with the policy server.

Method, system and apparatus for data session management in core mobile networks

A short message service (SMS) node detects that at least one request to deliver a plurality of short messages (SM) originates from a single user. Information (MSISDN, ISMI) related to recipients of the plurality of short messages is combined in a signaling message, and the signaling message is transmitted to a charging function (OFCS, OCS).

Charging for short message delivery

Controlling setting-up a connection in a mobile communication system includes storing, in at least one subscriber database, subscriber-oriented data for a subscriber registered in a home mobile radio network, entering the subscriber-oriented data in a subscriber database when the subscriber moves, and setting-up a connection for the subscriber with a mobile station using a mobile switching center coupled to the subscriber database.

Mobile communication system for controlling a connection setup

A method for ascertaining a billing tariff for billing for a data transfer, where a mobile communication terminal which is involved in the data transfer and has access rights for a data mobile radio network is situated in a visitor mobile radio network. The method involves setup of a data tunnel, used for transferring the data, prompting transfer of an item of location information which relates to the communication terminal from a switching center, temporarily associated with the communication terminal, in the visitor mobile radio network to the network gateway node in the data mobile radio network. The network gateway node transfers the item of location information to a billing system, and the billing system uses the item of location information to establish that the communication terminal is situated in the visitor mobile radio network. Thereupon and the billing system ascertains a billing tariff which is associated with the visitor mobile radio network.

Method for ascertaining a billing tariff for billing for a data transfer

A method for ascertaining a billing tariff for billing for a packet switched data transfer, where a mobile communication terminal which is involved in the data transfer and has access rights for a data mobile radio network is situated in a visitor mobile radio network. The method involves a data link being set up between a billing system, which performs billing for the data transfer, and a central subscriber register in the data mobile radio network, and this data link being used to transfer to the billing system an item of location information which relates to the current location of the communication terminal. The billing system uses the item of location information to establish that the communication terminal is situated in the visitor mobile radio network, and the billing system ascertains a billing tariff which is associated with the visitor mobile radio network.

Method for ascertaining a billing tariff for a data transfer

The invention relates to a method for transferring messages between communication terminals, including a control computer controlling message transfer which transfers a token to a first communication terminal and grants the first communication terminal authorization to transmit a message, and transfers a reservation message to a charging system, which asks the charging system to reserve resources for charging for the transfer of the message. After receiving the token, the first communication terminal starts to transmit the message, which is addressed to a second communication terminal, and portions of the message which have been transmitted by the first communication terminal are transferred to the control computer and are buffer-stored therein, and after receiving a reservation confirmation message transferred to the control computer by the charging system upon successful reservation the control computer transfers the message to the second communication terminal.
