Abstract: A telecommunications services apparatus, in a mobile telecommunications network, comprises means (2) for receiving a MAP Send Routing Information for Short Message (SRI_SM message) originating from another network and operate to forward the SRI_SM message to a home location register (4), means for receiving a response from the home location register (4) to the SRI_SM message, means for temporarily storing information relating to the SRI_SM response and operable to pass said response on to a network address identified as the originating address, and means for receiving a MAP Mobile Terminated Forward Short Message (MT_Fwd_SM message) from the other network and operable to correlate the MT_Fwd_SM message with a previously-sent SRI_SM response using stored information.

Abstract: A grooming technique for managing text message traffic in mobile telephone networks, such as SMS text messages, involves directing certain text messages to a first delivery means (30) which attempts text message delivery one or more times to a destination mobile switching centre (22) or to a host (24) without passing through a store and forward function. Other text messages are directed to a second delivery means, involving a short message service centre (14), which provides a store and forward function for repeated attempted delivery of the text messages.
