Solution Overview

Problem

The receiving efficiency of Multimedia Broadcast Multicast Service (MBMS) is relatively low in multi-carrier environments due to ineffective resource management and frequency allocation in existing technologies.

Innovation Solution

The network side activates or switches the UE to the frequency corresponding to the MBMS service of interest based on the UE's multi-carrier capability and serving cell frequency, improving MBMS receiving efficiency by optimizing frequency allocation and usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the network side uses traditional frequency allocation methods without considering UE multi-carrier capability, then the system is simpler to implement, but the MBMS receiving efficiency is low

Engineering Contradiction:
ImproveMBMS receiving efficiencyVSAvoidfrequency allocation management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic frequency allocation by determining the target frequency based on UE capability information and current serving cell frequency. The network side actively adjusts frequency allocation according to real-time conditions rather than using static allocation methods, thereby improving MBMS receiving efficiency while managing system complexity through adaptive control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the frequency parameter dynamically by selecting a target frequency from multiple available frequencies based on UE multi-carrier capability and current serving cell frequency. This parameter change approach allows the system to optimize MBMS receiving efficiency by adapting frequency allocation to specific UE capabilities and network conditions.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the network side activates multiple frequencies for MBMS service, then the MBMS receiving efficiency is improved, but the system load increases

Engineering Contradiction:
ImproveMBMS receiving efficiencyVSAvoidsystem load
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent applies local quality by tailoring frequency allocation to specific UE capabilities and conditions. Instead of uniformly activating all frequencies for all UEs, the network side determines the appropriate target frequency based on individual UE multi-carrier capability and current serving cell frequency, thereby improving MBMS receiving efficiency for each UE while avoiding unnecessary system load.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements partial action by activating only the necessary frequency resources required for MBMS service delivery. The network side determines the target frequency based on UE capability and current frequency, activating frequencies only when needed rather than maintaining all frequencies active, thus improving MBMS receiving efficiency while reducing overall system load.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A Multimedia Broadcast Multicast Service (MBMS) processing method is disclosed, in which a network side activates a frequency corresponding to the MBMS service that is of interest to a UE or switches the User Equipment (UE) to the frequency corresponding to the MBMS service that is of interest to the UE according to received information about the MBMS service that is of interest to the UE transmitted by the UE, the multi-carrier capability of the UE, and a frequency of a serving cell of the UE. The disclosure also provides a processing apparatus, receiving method and device for an MBMS service. By means of the technical solutions of the disclosure, in a multi-carrier environment, the network side activates the frequency corresponding to the MBMS service that is of interest to the UE or switches the UE to the frequency according to the information about the MBMS service that is of interest to the UE reported by the UE, so as to receive the MBMS service that is of interest to the UE, which solves the problem that the receiving efficiency of an MBMS service is relatively low in the multi-carrier environment, and achieves the effect of improving the MBMS receiving efficiency of the UE.
