SMS Priority Encoding Across SIP and SMPP Networks

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The SMPP protocol fails to differentiate and prioritize message priority levels, leading to delayed or lost critical communications during network congestion, particularly in emergency situations, and existing techniques consume resources without ensuring reliable prioritization.

Innovation Solution

A network device encodes SMS priority by converting SIP-based messages with priority headers into SMPP-based messages, maintaining priority levels through encoding and queuing strategies, ensuring differentiated routing and delivery across protocols.

1Productivity

If the SMPP protocol is used for high-volume SMS transmission, then message throughput and efficiency are improved, but the ability to differentiate and prioritize message priority levels is lost

Engineering Contradiction:

Improvemessage throughputVSAvoidmessage prioritization

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent introduces an intermediary encoding mechanism that translates SIP priority header information into SMPP priority fields. This intermediary layer allows the system to maintain compatibility with both protocols while preserving priority information through the conversion process, enabling high-volume SMPP transmission without losing prioritization capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the parameter representation of priority information by mapping SIP priority header values to corresponding SMPP priority field values. This parameter transformation allows the same priority concept to be expressed in different protocol formats, enabling both high throughput and prioritization to coexist.

Principle #35Parameter changes

2Use of energy by moving object

If existing techniques are used to handle priority SMS messages, then computing and networking resources are consumed, but reliable prioritization during network congestion is not ensured

Engineering Contradiction:

Improvecomputing resource consumptionVSAvoidmessage delivery reliability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent applies preliminary action by encoding priority information at the source (SIP side) before messages enter the high-volume transmission path. This advance encoding ensures that priority information is already embedded in the message stream, eliminating the need for resource-intensive real-time priority analysis during network congestion and ensuring reliable prioritization.

AI summary

A network device may receive a first protocol-based message that includes priority header information indicative of a priority level associated with a first user equipment (UE). The network device may encode the first protocol-based message into a second protocol-based message that includes a priority header field generated based on the priority header information. The network device may cause the second protocol-based message to be provided to a second UE associated with an intercarrier network.
