Label Information for Service Data Flow Management in Telecommunications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telecommunications networks require the establishment of EPC bearers for data packet transmission between user equipment and the network, which limits flexibility in managing quality-of-service profiles and packet data networks, as different service data flows are often transported within a single bearer, restricting independent handling and quality-of-service application.
Innovation Solution
The method involves using label information to indicate the termination points and quality-of-service profiles for each service data flow, allowing network nodes to apply correct treatment without the need for EPC bearers, enabling flexible handling of different service data flows by associating specific quality-of-service profiles and packet data networks with each flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If EPC bearers are used to transport service data flows, then data transmission between user equipment and network is established, but flexibility in managing quality-of-service profiles and packet data networks is limited
Solution Approach 1:
The patent segments the service data flow identification from the bearer structure by introducing label information that can independently identify different service data flows within a single bearer. This allows multiple quality-of-service profiles to be associated with different label values, enabling flexible management without requiring separate bearers for each service data flow.
Solution Approach 2:
The patent applies local quality by associating specific quality-of-service profiles with specific label information values rather than requiring separate bearers. Each label value can be locally configured with its own quality-of-service profile, termination point, and packet data network association, providing granular control over service characteristics.
2Productivity
If multiple service data flows are transported within a single bearer, then resource utilization is improved, but independent handling and quality-of-service application for each flow is restricted
Solution Approach 1:
The patent introduces label information as an intermediary mechanism that enables independent identification and handling of service data flows within a shared bearer. The label acts as a mediator that allows network nodes to distinguish between different service data flows and apply appropriate quality-of-service profiles, termination points, and packet data network routing without requiring separate bearers.
Solution Approach 2:
The patent makes the single bearer universal by enabling it to carry multiple service data flows with different quality-of-service requirements through the use of label information. The bearer structure becomes multi-functional, supporting diverse service types (e.g., voice, data, video) simultaneously while maintaining independent control over each flow's characteristics.
3Reliability
If EPC bearers are established for each service data flow, then quality-of-service profiles can be applied, but the complexity of bearer management and repeated packet filtering increases
Solution Approach 1:
The patent extracts the service data flow identification function from the bearer structure itself and places it in the label information field. This separation allows the bearer to remain a simple transport mechanism while the label carries the complex identification and quality-of-service association information, reducing bearer management complexity.
Solution Approach 2:
The patent performs preliminary configuration by associating quality-of-service profiles, termination points, and packet data networks with label information values in advance. This pre-configuration eliminates the need for complex runtime bearer management and repeated packet filtering, as network nodes can simply match incoming packets against pre-configured label associations.

AI summary
The invention relates to a method for handling communication between a telecommunications network and a user equipment, wherein the communication between the telecommunications network and the user equipment comprises at least one service data flow between, on the one hand, the user equipment and, on the other hand, a gateway node of the telecommunications network, wherein the at least one service data flow comprises data packets, wherein the data packets comprise data packets being sent, by the user equipment, towards the telecommunications network, and data packets being sent, by the gateway node of the telecommunications network, towards the user equipment, wherein the method comprises the step of using a label information for indicating the at least one service data flow such that any data packet belonging to the at least one service data flow and being transmitted in the direction from the user equipment to the gateway node or in the direction from the gateway node to the user equipment either comprises the label information or is transmitted with the label information, wherein the label information is indicative of at least one out of - a termination point of the at least one service data flow, - both termination points of the at least one service data flow, and - a quality-of-service level to be applied to the service data flow.
