IMS Data Channel for Cross-Network Service Sharing Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems enforce strict service level agreements between operators, limiting users to a least common denominator of services, preventing seamless communication and service sharing between devices on different networks.
Innovation Solution
A mechanism is provided to establish an Internet Protocol Multimedia Subsystem (IMS) data channel between devices on different networks, allowing a first network node to share services subscribed to by a first wireless device with a second wireless device, even if the second device does not subscribe to those services, thereby enabling an aggregated set of services in a communication session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strict service level agreements are enforced between operators, then service quality and reliability are maintained, but service versatility and adaptability are limited
Solution Approach 1:
The patent introduces an IMS data channel as an intermediary mechanism between devices on different networks. This data channel enables service data to be transmitted from a first device on a first network to a second device on a second network, allowing service sharing without requiring strict service level agreements between operators. The intermediary channel bypasses the need for operator-level service coordination while maintaining reliable service delivery.
2Reliability
If services are limited to the least common denominator between two devices, then compatibility and reliability are ensured, but service functionality and user experience are degraded
Solution Approach 1:
The patent adds a new dimension to service delivery by introducing an IMS data channel that operates parallel to traditional service channels. This additional dimension allows service data to be transmitted independently of operator service level agreements, enabling devices to access services beyond the least common denominator while maintaining compatibility through the established communication framework.
3Adaptability or versatility
If seamless service sharing between devices on different networks is enabled, then service adaptability and user experience are improved, but network complexity and coordination requirements increase
Solution Approach 1:
The patent extracts the service data transmission function from the operator network infrastructure and places it in the IMS data channel. This extraction removes the need for complex operator-level coordination and service level agreement management, simplifying the network architecture while enabling seamless service sharing between devices on different networks.

AI summary
A method performed by a first network node (12) for handling a communication session, wherein the first network node (12) is associated with a first communication network operated by a first operator. The first network node sets 5up a data channel between the first network node and a second wireless device (14). The second wireless device is associated with a second communication network operated by a second operator. The first network node further provides data over the setup data channel to the second wireless device (14), wherein the data is related to a service provided for a first wireless device serviced by the first operator.
