Uplink Resource Reuse for VoIP Transient Periods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless telecommunications systems, particularly in LTE networks, there is inefficiency in uplink resource allocation during transient periods of VoIP calls, where the resource assigned to a user is not immediately released, leading to waste, as the user may not have enough data to transmit, but cannot be used by other users during this transition.
Innovation Solution
The unused portion of the uplink resource allocated for VoIP can be dynamically reassigned to other data types, such as email or HTTP, allowing multiplexing with VoIP data in the MAC layer and mapped onto semi-persistent resources for transmission, optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uplink resources are allocated semi-persistently for VoIP to ensure reliable communication, then reliability of VoIP transmission is improved, but resource utilization efficiency deteriorates during transient periods when data is not available for transmission
Solution Approach 1:
The patent applies dynamics by making the resource allocation flexible rather than static. During transient periods, the MAC layer dynamically reassigns unused VoIP resources to other data types (email, HTTP, etc.), while during active VoIP transmission, the original semi-persistent allocation is maintained. This dynamic adaptation resolves the contradiction between reliability and resource efficiency.
Solution Approach 2:
The patent implements multi-functionality by enabling uplink resources to serve multiple purposes. The same uplink resources allocated for VoIP can be reused for other data types during transient periods when VoIP has no data to transmit. This universal resource usage resolves the contradiction by maintaining reliability for VoIP while improving overall resource utilization through alternative uses during idle periods.
2Loss of energy
If uplink resources are immediately released when VoIP data becomes unavailable, then resource utilization efficiency is improved, but reliability of VoIP communication deteriorates during transient periods
Solution Approach 1:
The system dynamically adjusts resource allocation based on real-time data availability. When VoIP data becomes unavailable, the resources are temporarily reassigned to other data types rather than being immediately released or permanently reserved. This dynamic approach maintains reliability by keeping resources available for VoIP when needed while improving efficiency through temporary reuse during transient idle periods.
Solution Approach 2:
The patent changes the parameter of resource allocation state from fixed to variable. During transient periods, the resource allocation parameter switches from dedicated VoIP allocation to shared allocation with other data types. When VoIP data becomes available again, the parameter switches back. This parameter change resolves the contradiction between efficiency and reliability.
3Reliability
If uplink resources are reserved for VoIP during transient periods, then reliability of VoIP transmission is maintained, but resource efficiency deteriorates as resources cannot be used by other users or applications
Solution Approach 1:
The patent enables uplink resources to perform multiple functions by allowing other data types (email, HTTP, etc.) to utilize the resources during transient periods when VoIP has no data to transmit. This multi-functionality resolves the contradiction between maintaining reliability and improving productivity, as resources are neither wasted nor permanently reserved but dynamically shared based on actual transmission needs.
Solution Approach 2:
The system implements self-service through automatic resource reassignment at the MAC layer. When VoIP enters a transient period with no data, the resources automatically become available for other applications without manual intervention. When VoIP data becomes available again, the resources are automatically reassigned back. This self-managing mechanism resolves the contradiction between reliability and productivity.
Data Source
AI summary
A system and method are disclosed that allows for uplink resource reuse. A user device is provided an uplink resource for a first data type. If the user device does not have enough data of the first data type to fill the granted uplink resource, the user device fills the granted uplink resource with a second data type.
