Messaging a receiving call party when prepaid credit of calling party is low to request them to 'call me'

摘要

The present invention relate to a messaging system for managing communications resources and are particularly suitable for providing a means for subscribers of a telecommunications network to continue participating in a communications service that would otherwise be ended due to the calling party having a low or zero balance of prepaid credit. The invention is generally applicable to users of a mobile network. The invention provides a messaging system for use by the telecommunications network to transmit a message to a remote party, where the remote party is identified by means of a telephone calling identifier associated with a call setup request for a telecommunications session received from a user of the telecommunications network. The messaging system comprises a storage system for storing data providing a predetermined definition of message content to be sent to the remote party. In response to a trigger event such as determining that the account balance available for said user participating in the requested communications session is below a predetermined threshold, the messaging system is arranged to initiate the transmission of a message to said remote party. The transmitted message contains message content that is defined at least in part by said definition of message content and can comprise a "call me message". This thereby ensures that a "call me" message reaches the remote party.
