Abstract: Systems, methods, apparatuses, and computer program products for providing security between WebRTC clients and IMS are provided. One method includes storing, by a network node, at least one parameter per internet protocol multimedia subsystem (IMS) subscription, where the at least one parameter comprises at least one identity of any web real time communication (WebRTC) web server function that is authorized to authenticate an IMS subscriber in WebRTC. The method may further include receiving a WebRTC web server function identity from a call state control function, comparing the received WebRTC web server function identity with the at least one parameter associated with the IMS subscription, and rejecting IMS communication when there is not a match between the received WebRTC web server function identity and the at least one parameter associated with the IMS subscription.

Abstract: Systems, methods, apparatuses, and computer program products for providing IMS level awareness of high latency device are provided. One method, when a UE attaches to EPC, receiving, at a network node, an indication that the UE is a high latency device. The method may also include assigning, to the UE, an IP address selected from a special IP address range that is designated specifically for high latency devices. When the UE performs IMS registration, the method may include determining that the UE is a high latency UE based on the UE's IP address provided with the IMS registration request and assigned during the EPC attach procedure.

Abstract: It is provided a method, comprising monitoring, for each of plural attempts of a web identity to register for an internet protocol multimedia service, if the respective attempt is received; generating, for each of the plural attempts if the respective attempt is received, a respective private user identification based on the web identity and a respective distinguishing identifier, wherein probability that two of the private user identifications have a same value is less than a predefined limit; providing the respective private user identification in response to the respective attempt.
