Solution Overview

Problem

Current Customized Multimedia Ringback Tone (CMR) services fail to consider the capabilities of User Equipment (UE) when delivering media services, leading to incompatible media information being played, which results in service failures and inability for UE to predict or indicate the service attribute to the user.

Innovation Solution

A method where a media service identifier is carried in the call setup request to indicate the attribute and capability required for the UE to process the media service, allowing the UE to prepare and receive media information matching its capabilities, and a server selects and delivers media information based on the UE's capabilities, ensuring compatibility and proper service delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the network delivers CMR service without considering UE capability, then the service can be provided universally to all users, but the media information may be incompatible with the UE's processing capability resulting in service failure

Engineering Contradiction:
Improveservice coverageVSAvoidservice success rate
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by indicating the media service attribute (such as CRBT or CRT type) in advance during the call setup phase through the network. This allows the UE to check its capability against the indicated service attribute before the service is delivered, and prepare accordingly. The capability checking and preparation happen beforehand, preventing service failure while maintaining universal service coverage.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the UE checks capability before receiving media service, then service compatibility is ensured, but the UE cannot predict or indicate the service attribute to the user in advance

Engineering Contradiction:
Improveservice compatibilityVSAvoidservice attribute information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent implements feedback by indicating the media service attribute (CRBT or CRT type) to the UE during the call setup phase, before the actual service delivery. This early indication allows the UE to provide feedback to the user about what service will be delivered, enabling the user to make informed decisions. The attribute information flows from network to UE, creating a feedback loop that maintains both compatibility and information transparency.

Inventive Principle:
Principle #23Feedback

3Reliability

If different processes are performed according to different UE capabilities, then service compatibility is improved, but the service processing complexity increases

Engineering Contradiction:
Improveservice compatibilityVSAvoidservice processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by having the UE perform capability checking and service preparation only for the specific media service attribute indicated by the network (such as CRBT or CRT type). Instead of implementing complex universal capability checking for all possible service types, the UE focuses its processing on the locally relevant service attribute that has been indicated. This reduces overall processing complexity while maintaining compatibility.

Inventive Principle:
Principle #3Local quality

AI summary

A method, an apparatus, a system, User Equipment (UE), and a server for receiving and delivering a media service are disclosed. The method for receiving a media service includes: judging whether a call setup request carries a media service identifier; and receiving media information indicated by the media service identifier if the call setup request carries the media service identifier. At the time of exchanging information, an identifier is carried in the information to indicate the attribute of the media information to be received by the UE, and therefore, the UE can notifythe imminent or ongoing service to the user and prepare for receiving the media information according to the attribute of the media information. The identifier also indicates the media service processingcapability of the UE, and corresponding operations are performed according to different capabilities of the UE. Therefore, the UE receives the media information that matches its media service processingcapability.
