Base Station Group Identifier Mapping for Wireless Multicast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of devices in wireless communication systems increases, managing traffic delivery efficiently becomes challenging due to bandwidth constraints and overhead costs, particularly in multicast communications where repetitive transmission of the same information to multiple devices is inefficient.
Innovation Solution
Implementing a method where a base station maps a device group identifier (DGID) to a common identifier, such as a group connection identifier (CID) or group flow identifier (FID), allowing for multicast transmission of information to groups of devices over wireless networks, reducing the need for individual transmissions and conserving bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual communications are used to send traffic to each device, then each device receives its traffic reliably, but network overhead increases and bandwidth is wasted
Solution Approach 1:
The patent merges multiple individual traffic streams into a single group traffic stream by assigning a common group CID to multiple devices. The base station sends one copy of the traffic to the group instead of sending separate copies to each device, thereby reducing bandwidth consumption while ensuring all group members receive the traffic reliably.
Solution Approach 2:
The group CID serves multiple functions: it identifies the group of devices, enables multicast traffic delivery, and allows the base station to efficiently manage traffic for multiple devices simultaneously. This universal identifier reduces network overhead while maintaining reliable delivery to all intended recipients.
2Loss of energy
If multicast communications are implemented to reduce overhead, then bandwidth is conserved, but device complexity increases due to group management requirements
Solution Approach 1:
The base station acts as an intermediary that manages group formation and CID assignment. It maintains the mapping between device CIDs and group CIDs, handling the complexity of group management centrally rather than requiring complex coordination between devices. This reduces device complexity while enabling efficient multicast communications.
3Quantity of substance
If the number of devices in the wireless system increases, then system capacity and coverage improve, but network overhead and management complexity increase
Solution Approach 1:
The patent groups multiple devices into logical groups identified by group CIDs, merging individual device management into group-level management. This allows the system to handle a large number of devices efficiently by managing traffic at the group level rather than individually, reducing overhead as device quantity increases.

AI summary
Techniques for managing traffic delivery to a group of devices are described. In some embodiments, a method for communicating in a wireless network may comprise receiving, at a base station, information intended for a group of devices identified by a device group identifier (DGID), mapping, at the base station, the DGID to a common identifier known by each device in the group of devices, and multicasting the information from the base station to the group of devices over one or more channels of the wireless network using the common identifier. Other embodiments are described and claimed.
