摘要:
A method facilitates provisioning of pre paid wireless services. Credit refresh operations involving a pre paid wireless communication device involve SMS messages transmitted to the device over the air. The device uses tariff tables to keep track of a call's impact on available credit. The tariff tables are updatable at the service provider's discretion using SMS messages.

A communications device such as a mobile telephone (1) responds to the input of a dialled number for a call destination (2) by generating and outputting a request message transmitted to a control centre (7) via a telecommunications system (3). The device receives a response message from the control centre containing routing data and credit data representing remaining credit within an account limit of the subscriber. An outgoing communications session is then initiated using the routing data which may for example enable a dialled telephone number to be modified to achieve optimum routing to the call destination via one or more preferred networks. The device also includes a credit control application (83) for limiting the duration of the communication in accordance with the credit data. Mobile telephones may thereby be used with a prepayment subscription account even during roaming operation in which the mobile telephone registers with a network other than the subscriber's home network.

The invention relates to a method for providing price information to subscribers of a digital mobile communication network. The aim of the invention is to inform the subscriber of the cost of a call he/she is about to make, in a simple manner. To this end, when the subscriber dials a call number, he/she obtains information on the rate to expect for a communication by means of short messaging service (SMS).

A system includes a database configured to store account information relating to users of a telecommunications network. Additionally, a session initiation protocol (SIP) server receives first messages initiating call transfers. The server appends billing information and a digital signature to the first message based on account information of one of the users stored in the database. The digital signature provides for authentication of the call transfers.

The present invention proposes a method for billing a subscriber (A, B) for data transmission in a communication network (NW; AN, CN) said communication network comprising at least one call control entity (CSCF) for controlling calls to be established from a subscriber (A, B) to a communication destination (B, A), said method comprising the steps of: forwarding a signaling message from said subscriber (A) to said destination (B), said signaling message comprising a message header and a message body, said message header including information descriptive for a content carried in the message body, analyzing said signaling message header at said call control entity (CSCF), and generating billing information based on the result of analysis.

A method of providing charge information to a user of a mobile terminal (2), which information relates to an IP connection or connections being used by the user. The method comprises the steps of identifying the terminal (2) or the user to a charge control node (CCN) (10) located in a home network (1) of the terminal (2) or user and, for the duration of the IP connection(s), using the existing connection or one of the existing connections to transport a stream of charge information messages from the CCN (10) to the mobile terminal (2).

A communication service provider accounting server is used to track communication session usage by a client of the service provider. The accounting server receives an indication identifying a client that has commenced a communication session and an indication identifying that the client has terminated the communication session. The accounting server further provides periodic status request messages to the client and receives a sequence of status response messages in response thereto from the client. The accounting server determines a session termination time as the earlier of receipt of the indication that the client has terminated the communication session and making a determination that the sequence of status messages have ceased.

A real time streaming media session client operates with a communication service provider system. The client generates a session signaling message to the system identifying an endpoint and receives a response message. The response message includes an endpoint address for the real time streaming media session. The client commences a real time streaming media session with destination address. The client periodically sends session status responses to the system in response to session status requests sent by the system. The client also terminates the session and reports the session termination time along with a session identifier to the system in response to a call detail record backup request by the system.
摘要:
In order to provide a network node using an IP telephony signalling protocol, such as SIP, with service reference information needed for billing purposes, for example, the service reference information is added to an IP telephony signalling protocol message and the IP telephony signalling protocol message is then sent to the network node.
