Mobile Device Bearer Management Without Default Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems, particularly in LTE environments, face challenges in managing bearers for millions of M2M devices, leading to Gateway capacity overruns and increased costs, as each device is assumed to have a default bearer, resulting in inefficient resource allocation and potential connectivity failures.
Innovation Solution
A control module is introduced to manage bearers by requesting an attached status without a basic bearer allocation, allowing devices to maintain communication sessions without active bearers, thereby releasing resources when idle and optimizing network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each M2M device is attached to EPS with a default bearer, then connectivity is ensured, but Gateway capacity is overrun and costs increase
Solution Approach 1:
The patent extracts the default bearer allocation from the mandatory attachment procedure. Devices can now attach to the EPS without being allocated a default bearer, separating the attachment function from the bearer allocation function. This reduces the number of active bearers in the Gateway while maintaining connectivity capability.
Solution Approach 2:
The patent changes the parameter of bearer allocation from mandatory to optional. By introducing a new attachment mode where the default bearer is not allocated, the system allows devices to remain attached with zero bearers, fundamentally changing the relationship between attachment status and bearer presence.
2Duration of action of moving object
If default bearers are allocated to all attached devices, then continuous communication is enabled, but resource allocation becomes inefficient
Solution Approach 1:
Instead of continuously maintaining default bearers for all attached devices, the patent enables bearers to be allocated periodically or on-demand based on actual communication needs. Devices can attach without bearers and allocate them temporarily when data transmission is required, then release them when idle.
Solution Approach 2:
The patent applies partial action by allocating bearers only when necessary rather than continuously. Devices can maintain attachment status without active bearers, and bearers are established partially or temporarily only when communication is needed, reducing overall resource consumption.
3Quantity of substance
If fewer bearers are active to reduce costs, then Gateway capacity is optimized, but connectivity may fail for some user equipments
Solution Approach 1:
The patent makes the attachment mechanism universal by decoupling it from bearer allocation. The same attachment procedure works whether or not a default bearer is allocated, allowing the system to handle both scenarios (with and without bearers) through a unified mechanism. This ensures connectivity is maintained through attachment even when bearers are not active.

AI summary
The present invention proposes devices, methods and computer program products in relation to mobile communication. In particular, it relates to those devices, methods and computer program products concerning packet-based communication. The invention proposes an apparatus, comprising a control module configured to cause requesting an attached status, in which the apparatus is communicatively attached to another apparatus, control a transceiver which is capable of communicating with the other apparatus via a medium by use of a basic bearer allocated by the other apparatus in the attached status, cause generating a basic bearer operating information to be transmitted by the transceiver, the basic bearer operating information indicating that the apparatus is adapted to stay attached without a basic bearer allocation, and cause the transceiver to transmit the basic bearer operating information to the other apparatus.
