Processing data

An apparatus for use in constructing authorization requests in a telecommunications network, the network comprising:

• a subscriber configuration network node configured to store subscriber configuration data for a plurality of subscriber devices;
• and
• a user identity database configured to store user identity data for identifying subscribers in the network,
• the apparatus comprising a network node separate from the subscriber configuration network node, the apparatus comprising at least one processor, and at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to:
• receive, at the network node separate from the subscriber configuration network node, a request to access configuration data associated with a subscriber from the subscriber configuration network node;
• in response to the received access request comprising a private user identity for the subscriber, but not a public user identity for the subscriber:
• retrieve, at the network node separate from the subscriber configuration network node, from the user identity database, a public user identity for the subscriber, the retrieval being carried out on the basis of the private user identity for the subscriber comprised in the received access request, wherein the user identity database is separate from the subscriber configuration network node;
• and
• transmit, at the network node separate from the subscriber configuration network node, an authorization request to the subscriber configuration network node comprising the public user identity retrieved from the user identity database and the private user identity comprised in the received access request.

A computer program product comprising a non-transitory computer-readable storage medium having computer readable instructions stored thereon, the computer readable instructions being executable by a computerized device to cause the computerized device to perform a method for constructing authorization requests in a telecommunications network, the network comprising:

• a subscriber configuration network node configured to store subscriber configuration data for a plurality of subscriber devices;
• and
• a user identity database configured to store user identity data for identifying subscribers in the network,
• the method comprising:
• receiving, at a network node separate from the subscriber configuration network node, a request to access configuration data associated with a subscriber from the subscriber configuration network node;
• in response to the received access request comprising a private user identity for the subscriber, but not a public user identity for the subscriber:
• retrieving, at the network node separate from the subscriber configuration network node, from the user identity database, a public user identity for the subscriber, the retrieval being carried out on the basis of the private user identity for the subscriber comprised 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 comprising the public user identity retrieved from the user identity database and the private user identity comprised in the received access request.
