Access Network Device VoLTE Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE networks, the setup delay of VoLTE voice sessions increases when network resources are limited, as existing methods do not prioritize resource allocation effectively for VoLTE calls.
Innovation Solution
The proposed method involves an access network device allocating uplink and downlink transmission resources within specific time periods after receiving connection setup messages from user equipment, ensuring timely resource allocation for VoLTE voice sessions by starting timers for resource scheduling requests and data packets, thereby reducing transmission delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If network resources are limited and existing resource allocation methods are used, then resource allocation is performed, but VoLTE voice session setup delay increases
Solution Approach 1:
The access network device starts a timer upon receiving the connection setup message indicating VoLTE service, and proactively allocates uplink and downlink transmission resources before they are actually needed for transmission. This preliminary resource allocation avoids delays that would occur if resources were allocated reactively after transmission requests are made.
Solution Approach 2:
The patent changes the resource allocation timing parameter by introducing a specific time window (timer duration) during which resources are pre-allocated. The timer value can be configured to match the expected transmission timing, ensuring resources are ready exactly when needed without premature allocation waste.
2Loss of time
If priority resource allocation for VoLTE is implemented within a specific time period, then VoLTE session setup delay is reduced, but network resource management complexity increases
Solution Approach 1:
The access network device starts a timer upon receiving the connection setup message indicating VoLTE service, and proactively allocates uplink and downlink transmission resources before they are actually needed for transmission. This preliminary resource allocation avoids delays that would occur if resources were allocated reactively after transmission requests are made.
Solution Approach 2:
The system uses automated timer-based triggering and resource allocation without requiring manual intervention or complex scheduling algorithms. The timer automatically expires and triggers resource allocation, and the system self-manages the priority queuing and resource assignment based on pre-defined rules, reducing operational complexity.
3Speed
If uplink and downlink transmission resources are allocated within a first time period after receiving connection setup message, then transmission delay is reduced, but network resource consumption increases
Solution Approach 1:
The access network device starts a timer upon receiving the connection setup message indicating VoLTE service, and proactively allocates uplink and downlink transmission resources before they are actually needed for transmission. This preliminary resource allocation avoids delays that would occur if resources were allocated reactively after transmission requests are made.
Solution Approach 2:
The resource allocation is dynamic and conditional - resources are allocated within the time period only if actually needed for VoLTE transmissions. The system monitors transmission requirements and releases resources if not utilized, preventing waste while ensuring availability when needed.

AI summary
A service processing method and an apparatus are provided. The method includes: receiving, by an access network device, a connection setup message sent by user equipment UE, where the connection setup message includes first voice session indication information, and the first voice session indication information is used to indicate that the connection setup message is sent due to a Voice over Long Term Evolution VoLTE voice session; and preferentially allocating, by the access network device within a first time period that is after the access network device receives the connection setup request message, an uplink transmission resource to the UE if receiving a resource scheduling request message sent by the UE.
