Abstract: Systems and method are provided to reduce redundant data transfers for service profiles within a wireless core network. A network device in the core network receives, from a mobility management entity (MME), a user profile request. The user profile request includes a user identifier for an end device. The network device determines that a user profile corresponding to the user identifier includes a shared service profile and determines, when the user profile includes a shared service profile, whether the MME has stored the shared service profile. When the MME has not stored the shared service profile, the network device sends, to the MME, the shared service profile and a shared profile identifier for the shared service profile. The network device sends, to the MME, a response to the user profile request, the response including the user identifier and the shared profile identifier for the shared service profile.
