SLICE-BASED SECURITY PROTOCOL SELECTION FOR INTERNET PROTOCOL MULTIMEDIA SUBSYSTEM (IMS)

Abstract: various embodiments comprise a wireless communication network to perform slice-based security protocol selection for internet protocol multimedia subsystem (ims). in some examples, the wireless communication network comprises a call session control function (cscf). the cscf receives an ims registration request transferred by a wireless user device, generates an authorization request that includes an address value pair (avp) requesting a slice identifier (id) for the wireless user device, and transfers the authorization request to a network data system. the cscf receives an authorization response from the network data system that includes the slice id for the wireless user device. the cscf selects a security protocol for authenticating the wireless user device based on the slice id. the cscf transfers an authentication challenge for delivery to the wireless user device and establishes a secure communication channel with the wireless user device using the selected security protocol.
