1. A method of constructing authorization requests in a telecommunications network, the method comprising: receiving, at a network node separate from a subscriber configuration network node, a request to access configuration data associated with a subscriber stored at the subscriber configuration network node wherein the received access request comprises a private user identity for the subscriber, but not a public user identity for the subscriber, and wherein the subscriber configuration network node is configured to store subscriber configuration data for a plurality of subscriber devices; retrieving, at the network node separate from the subscriber configuration network node, in response to the received access request, a public user identity for the subscriber from a user identity database configured to store user identity data for identifying subscribers in the telecommunications network, the retrieval of the public user identity being carried out based on the private user identity for the subscriber included in the received access request, wherein the user identity database is separate from the subscriber configuration network node; and transmitting, at the network node separate from the subscriber configuration network node, an authorization request to the subscriber configuration network node, wherein the transmitted authorization request comprises the public user identity retrieved from the user identity database and the private user identity comprised in the received access request.
