Broadcast Management Unit for Cellular Network Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for data services in cellular communications networks leads to bandwidth limitations, resulting in poor user experience, errors, and non-availability of digital content due to capacity overload in cells, as existing technologies rely on unicast transmissions that consume significant bandwidth.
Innovation Solution
Implementing a Broadcast Management unit that recommends and provides digital content through broadcast or multicast instead of unicast, allowing multiple user equipment to receive the same digital content simultaneously, reducing bandwidth requirements and improving service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unicast transmissions are used to deliver digital content to user equipment, then individual content delivery is achieved, but bandwidth consumption increases and capacity overload occurs
Solution Approach 1:
The patent merges multiple unicast transmissions into a single broadcast or multicast transmission by identifying that multiple user equipments are requesting the same or similar digital content. The network node consolidates these requests and delivers the content through a shared transmission channel, thereby reducing bandwidth consumption while maintaining reliable content delivery to all requesting devices.
Solution Approach 2:
The patent implements a universal content delivery mechanism where a single broadcast or multicast transmission serves multiple user equipments simultaneously. The system determines whether to use unicast, broadcast, or multicast based on the number of requesting devices, making the transmission method adaptable and multi-functional to optimize bandwidth usage across different scenarios.
2Quantity of substance
If broadcast or multicast is used to deliver digital content, then bandwidth efficiency improves, but system complexity increases due to request monitoring and transmission type determination
Solution Approach 1:
The patent applies preliminary action by having user equipments send content requests to the network node before actual content delivery. The network node monitors these requests in advance, identifies when multiple devices request the same content, and proactively determines the optimal transmission type (broadcast or multicast) before initiating the actual content delivery, thereby simplifying the overall system operation.
Solution Approach 2:
The patent implements feedback mechanisms where user equipments provide information about their content requests and reception status to the network node. This feedback enables the network node to dynamically adjust transmission types based on real-time network conditions and user demand, optimizing bandwidth efficiency while managing system complexity through informed decision-making.
3Adaptability or versatility
If multiple unicast transmissions are used to serve multiple user equipments, then individual content access is enabled, but capacity overload and service quality degradation occur
Solution Approach 1:
The patent implements dynamic transmission type selection that adapts to the number of user equipments requesting content. The system transitions from unicast (for single users) to broadcast or multicast (for multiple users) based on real-time demand, thereby maintaining content access flexibility while optimizing network capacity utilization and preventing capacity overload.

AI summary
A method in, and a Broadcast Management unit (163) for recommending and providing digital content to a user equipment (120), and a method in and a user equipment (120) for accessing recommended digital content. The user equipment is served by a base station in a cellular communications network. The Broadcast management unit decides (301, 401, 501) to recommend a digital content to the user equipment (120) and one or more additional user equipments (121, 122, 123) and provides broadcast or multicast of the digital content in a service area (105. The user equipment registers (306; 409; 701) a request for one or more digital contents that are recommended and then identifies, in response to the registered request, a digital content that is recommended and available from broadcast or multicast by the base station (110). The user equipment (120) displays (309, 411, 703), in response to the identified digital content, a representation of the digital content, which representation is selectable for access to the digital content.
