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.

Internet protocol (IP) multimedia subsystem (IMS) level awareness of high latency device

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.

Multiple parallel WebRTC accesses to IMS

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.

Security for access to the IP multimedia subsystem (IMS) with web real time communication (WebRTC)

A method, apparatus, and computer readable medium is provided for a reverse single radio voice call continuity handover procedure, where an access transfer control function is only allocated dynamically during a call setup phase, if the access transfer control function is needed to support the reverse single radio voice call continuity handover procedure.

Minimal access transfer control function requirements for single radio voice call continuity handover

For multiple registration of a multimodal communication terminal (MKE) via at least one access network in an IMS-based service communication system in a mobile and/or convergent communication system, where the multimodal communication terminal (MKE) is registered for at least one communication service via a first access network (WIAN) in at least one service control unit in the IMS-based service communication system (S-CSCF), a registration message with an access network identifier (ZK) is produced and is transmitted to the at least one service control unit (S-CSCF) in the IMS-based service communication system. The at least one service control unit evaluates the access network identifier (ZK) and takes it as a basis for performing further registration of the multimodal communication terminal in the IMS-based service communication system (S-CSCF).

Method for multiple registration of a multimodal communication terminal

The present invention relates to an S-CSCF receiving a terminating request associated with a called user and executing services for the called user. The S-CSCF determines an indication in Session Case indicating originating services handling in call forwarding situation, and based on this executes a subset of services for the user.
