US Patent 10149168 Secured paging

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a paging message that includes a secured UE identifier calculated based on a security configuration negotiated between the UE and a trusted source, e.g., a mobility management entity (MME) of the core network. The UE may determine whether the paging message is received from the trusted source or an untrusted source based on the secured UE identifier. The UE may transmit a connection request message based on the determination that the paging message is received from a trusted source.
