MME eNodeB Deployment via 32-bit Global Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Evolved Packet System (EPS) network is unable to meet the demand for a sufficient number of evolved Node Bs due to the limited number of identifiers, which restricts the deployment of e Node Bs in the EPS network.
Innovation Solution
A method and device on the Mobility Management Entity (MME) side that acquires a connection establishment request from an e Node B, searches for corresponding e Node B information using a global identifier, and deploys the e Node B if not found, thereby increasing the number of e Node Bs by extending the identifier range from 0-65535 to 0-4294967295.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the traditional two-layer network structure (RNC and Node B) is used with the original Global RNC-ID structure, then the system maintains compatibility with legacy 3G networks, but the maximum number of deployable e Node Bs is limited to 65535
Solution Approach 1:
The patent extends the identifier space by adding a new dimension to the identifier structure. Instead of using only 16 bits (0-65535), the system now uses 32 bits by incorporating both RNC-ID and e Node B-ID components, effectively moving from a 2-byte to a 4-byte identifier space. This dimensional expansion allows over 4 billion unique identifiers while maintaining the hierarchical structure needed for network management.
Solution Approach 2:
The global e Node B identifier is segmented into multiple components: RNC-ID (4 bits) and e Node B-ID (12 bits) within the 32-bit space. This segmentation allows the system to maintain hierarchical network management capabilities while expanding the total addressable space. The segmented structure enables efficient routing and management operations while supporting a much larger number of e Node Bs than the original flat 16-bit identifier system.
2Quantity of substance
If the identifier range is extended from 0-65535 to 0-4294967295, then the number of deployable e Node Bs increases significantly, but the complexity of identifier management and processing increases
Solution Approach 1:
The 32-bit global identifier is segmented into RNC-ID (high-order bits) and e Node B-ID (low-order bits). This segmentation allows network elements to process identifiers in a hierarchical manner, first determining the RNC based on the high-order bits, then identifying the specific e Node B within that RNC using the low-order bits. This reduces the complexity of global identifier management by breaking it down into localized, manageable segments.
Solution Approach 2:
The patent changes the parameter structure of the identifier from a single 16-bit value to a composite 32-bit structure with specific bit allocations for different functional components. This parameter change enables the system to maintain efficient processing by preserving the hierarchical relationships in the identifier structure, allowing network elements to extract and process relevant portions of the identifier based on their specific functions without needing to handle the entire 32-bit space uniformly.

AI summary
A Method and device for deploying evolved nodes are provided in the present invention, and the method comprises: a MME acquires a connection establishment request from an e Node B, wherein the connection establishment request carries a global identifier of the e Node B; the MME acquires the global identifier, and searches for corresponding e Node B information according to the global identifier, and if the corresponding e Node B information cannot be found, the MME deploys the e Node B. With the present invention, the MME in a mobile communication packet domain evolved system can directly deploy e Node B, which increases the number of e Node B in the mobile communication packet domain evolved system, and satisfies the demand of the mobile communication packet domain evolved system on e Node B.
