Described herein is a node of a telecommunications network configured to determine that a primary index for data repositories of the telecommunications network is operating in a fail-open mode and, in response, provide a request received by the node to substantially all data repositories referred to by the primary index. The node is further configured to receive a response from one of the data repositories and, based at least in part on the response, build a secondary index mapping data repositories to subscriber identifiers. When a further request is received by the node in fail-open mode, the node may refer to the secondary index first and, if the subscriber identifier from the further request is not present in the secondary index, provide the further request to substantially all data repositories referred to by the primary index.

Fail-open operation for data repository indices

In some implementations, a telecommunications network can include a core network device communicatively connectable with user equipment (UE). The core network device can receive, via a network interface, an indication of a change to a user preference associated with the user device. The core network device can transmit a notification message including a pseudonymous identifier, the notification message based at least in part on the indication of the change. The UE can transmit, via a network interface, information of an account associated with the UE to a content provider. The information can include the pseudonymous identifier. The UE can then render content received from the content provider. The content provider can receive, via a network, the pseudonymous identifier and a request for content. The content provider can determine a quality setting associated with the pseudonymous identifier, and provide the content based at least in part on the quality setting.
