20090111489 | TELECOMMUNICATIONS SERVICES APPARATUS AND METHODS - A home location register (HLR) in a mobile telecommunications network is programmed to forward a selected subset of routing information request messages (SRI SM) to a message router (SMS Router), instead of the home location register providing the usual response. The message router then generates a modified response to the routing information request message, in consequence of the modified response receives the mobile terminated text message associated with the routing information request message, derives the destination MSISDN requested by the message sender associated with the mobile terminated text message, and queries the home location register to determine delivery information relating to the intended destination of the text message, such as a diverted destination. | 04-30-2009 |
