Gateway Support Node RNC Capability Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telecommunications networks, especially those using HSPA, the mobility management and signaling load increase due to frequent handovers between base stations, leading to over-dimensioning of SGSNs and inefficient resource allocation, as each RNC is treated similarly regardless of its capabilities, resulting in suboptimal network performance.
Innovation Solution
A method to dynamically manage radio telecommunications networks by detecting the number of base transceiver stations controlled by each RNC and verifying if the configuration allows connection to the serving gateway support node, allowing only capable RNCs to connect and enabling direct tunnel technology for user data transfer, thereby reducing signaling and resource requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all RNCs are treated similarly regardless of capabilities, then network compatibility is maintained, but resource allocation becomes inefficient and signaling load increases
Solution Approach 1:
The patent applies local quality by differentiating RNC handling based on their specific capabilities. The SGSN verifies whether an RNC is I-HSPA capable and treats capable RNCs differently by allowing direct tunnel connections, while non-capable RNCs use traditional routing through the SGSN. This localized differentiation optimizes resource allocation for each RNC type while maintaining overall network compatibility.
2Reliability
If SGSN is over-dimensioned to handle excessive mobility management, then network reliability is improved, but device complexity and resource waste increase
Solution Approach 1:
The patent implements preliminary action by having the SGSN verify RNC capabilities before establishing connections. The system proactively identifies I-HSPA capable RNCs and configures direct tunnel relationships in advance, preventing future mobility management overload. This preliminary differentiation allows the SGSN to be properly dimensioned without over-provisioning, reducing complexity while maintaining reliability.
3Loss of energy
If direct tunnel technology is implemented for I-HSPA RNCs, then signaling load is reduced, but device complexity increases
Solution Approach 1:
The patent uses the SGSN as an intermediary that mediates between I-HSPA capable RNCs and the core network. The SGSN verifies RNC capabilities and establishes direct tunnel relationships, acting as a smart gateway that simplifies the overall system architecture. This intermediary approach reduces signaling load by enabling direct connections where appropriate while maintaining the SGSN's coordination role, balancing complexity reduction with functional requirements.

AI summary
Management of a radio telecommunications network, in which a plurality of a radio network controllers (RNCs) (150) are served with a gateway support node (170) having a given configuration. An added RNC connected to the radio telecommunications network is detected and then it is detected the serving gateway support node if the added RNC is a flat radio access node. If the added RNC is detected as a flat radio access node, it is verified whether the configuration allows serving the added RNC and if yes, the added RNC is connected with the serving gateway support node and correspondingly the configuration is modified. Alternatively, if the added RNC is detected as not being a flat radio access node, connecting the added RNC with the serving gateway support node is refused.
