Capability Identifier Allocation for Wireless Transmission Resource Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, the increasing length of capability information for terminal devices exceeds the transmission capacity of air interfaces between access network devices and core network devices, necessitating a method to conserve transmission resources.
Innovation Solution
An identifier allocation method where a core network device allocates a capability information identifier to a terminal device, allowing it to transmit the identifier instead of the capability information, thereby reducing transmission resources required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device sends complete capability information to the access network device and core network device, then the capability information can be accurately obtained and stored, but the transmission resources are excessively consumed when the capability information length increases
Solution Approach 1:
The patent creates a simplified copy (capability information identifier) that represents the complete capability information. Instead of transmitting the full capability information data, the system transmits this identifier copy which can be looked up in a database to retrieve the actual capability information, thereby significantly reducing transmission resource consumption while maintaining information accuracy.
Solution Approach 2:
The patent introduces an intermediary mechanism - a database storing the mapping relationship between capability information identifiers and actual capability information. This intermediary allows the system to transmit only the identifier through the air interface and core network interface, while the complete capability information is retrieved from the database, thus reducing transmission overhead without losing information integrity.
2Loss of energy
If the terminal device sends capability information identifier instead of complete capability information, then transmission resources are saved, but the system needs to maintain additional mapping relationships between identifiers and capability information
Solution Approach 1:
The patent implements self-service by allowing the terminal device to autonomously determine whether to send capability information or capability information identifier based on whether it has pre-configured identifiers. The access network device also performs self-service by checking its database for existing mapping relationships before requesting capability information, reducing the need for complex centralized control mechanisms.
Solution Approach 2:
The patent applies preliminary action by pre-configuring capability information identifiers in the terminal device and pre-storing mapping relationships in the access network device database before actual capability information transmission is needed. This preparation work is done in advance during device initialization or previous communication sessions, so that during normal operation, only the lightweight identifier needs to be transmitted.
3Speed
If the access network device stores capability information locally, then quick access is achieved, but the core network device cannot share capability information with other access network devices
Solution Approach 1:
The patent makes the capability information system universal by using standardized capability information identifiers that can be recognized and looked up by any access network device or core network device in the network. The identifier system serves multiple functions: it enables local quick access when the identifier is cached locally, and it enables network-wide sharing when the identifier is transmitted through the core network to other access network devices, all using the same identifier-based mechanism.

AI summary
The embodiments of this application disclose an identifier allocation method and apparatus. The method includes: receiving, by a first core network device, a first request from a terminal device; allocating, by the first core network device, a first capability information identifier; and sending, by the first core network device, a first response to the terminal device, where the first response carries the first capability information identifier. Based on this method, the first core network device can allocate a capability information identifier to the terminal device, so that the terminal device can send the capability information identifier instead of capability information to another device, thereby helping save transmission resources for transmitting the capability information.
