Description

Split computation in an internet protocol multimedia subsystem Technical Field Various examples of the present disclosure relate to communication networks and, in particular, to methods, apparatuses, systems and computer programs for split computation in communication networks including internet protocol multimedia subsystems (IMS). Background A communication network may be considered a facility that enables communication between two or more communication devices, provides access to a data network for communication devices, delivers services provided by third party applications to communication devices, or provides services provided by a communication network to communication devices. A mobile, cellular or wireless communication network is one example of a communication network. The communication device may be provided with a service by an application server. The communication network and the communication device may operate according to cellular technology (also referred to as radio access technology), such as GSM, UTMS, LTE, LTE-a or the like. Cellular technology is standardized by various standards organizations, such as those provided by 3GPP (third generation partnership project) or ETSI (european telecommunications standards institute). A communication network operating according to cellular technology standardized by 3GPP is commonly referred to as a 3GPP network. A communication network (e.g., a 5G network or a 6G network) includes an access network (e.g., a wireless access network) that can wirelessly communicate with one or more communication devices by sharing available resources (e.g., bandwidth, transmit power, etc.) of the access network (e.g., the wireless access network). The communication network may also establish a reliable, secure connection between the communication device and a core network of the communication network via the access network. A communication network (e.g., a 5G network) may provide enhanced mobile broadband services (e.g., telephony, video, data, short message services), ultra-reliable low-latency communication services (e.g., real-time services such as XR services), or large-scale machine type communication services to communication devices.
