What is SMS Hubbing in Telecom?

SMS hubbing is a new framework for the international flow of SMS between operators. It fundamentally changes the way that international mobile interoperability works by deploying hubs to handle SMS traffic and provide wider SMS coverage.

What is SMS Hubbing in Telecom?

The GSM Association (GSMA) developed the SMS Hubbing trials in 2006 as a component of the Open Connectivity project after realizing that SMS Hubbing offered a solution to an issue impeding the further expansion of international SMS. This program defined standards and regulations that SMS hubs should adhere to, and it also built a new framework for worldwide SMS interoperability.

Every subscriber expects to be able to send SMS messages to other customers, regardless of the nation or mobile network, regardless of the operator's level of maturity or subscriber base.

History of SMS Hubbing

The way the GSM world is connected is what leads to the lack of complete international SMS interoperability. Every mobile operator must set up SMS interworking with every other mobile operator. This means that international SMS can only move between operators if a bilateral roaming agreement is in place.

Although bilateral interworking and roaming agreements between operators are the only means of achieving SMS interoperability, it is doubtful that this method would allow for complete worldwide SMS reach since putting up several agreements would be expensive and time-consuming. Furthermore, the additional cost of setting up an extra interworking link may not be justified by the income gains.

By connecting to independent hubs that have various agreements with different operators, SMS hubbing allows mobile operators (also known as "client operators") to have extensive worldwide SMS coverage. These hubs may then route messages on behalf of the client operators.

SMS Hubbing operates on the same principles as the voice connectivity model. Voice traffic is routed via telehouses, which are essentially voice hubs, as opposed to depending on expensive and many individual agreements. Similarly, several operators establish connections with hubs to forward MMS messages, aiming to address the numerous interoperability issues associated with this messaging system. The goal of SMS Hubbing is to streamline the SMS interworking system by displacing a large portion of the pointless, duplicate expenditures in international agreements that mobile carriers have historically made. In addition, SMS Hubbing aims to improve SMS service quality by implementing end-to-end quality of service via Service Level Agreements (SLAs).

SMS Hubbing does not substitute bilateral agreements. For users to have the option to roam outside of their home network, roaming agreements must be established by each operator. It makes sense for mobile carriers to assign SMS traffic originating from unconnected locations to an SMS hub outside of the primary roaming agreements that drive most international voice and messaging traffic.

Advantages of SMS Hubbing

Market Reach and Access

Through partnerships inside the hub, telecom carriers may expand their market reach by using one other's subscriber bases. Gaining access to a larger consumer base may increase market share and earnings potential.

Dynamic Resource Allocation

By allowing for the dynamic distribution of resources in response to actual demand, centralized hubs guarantee effective utilization of network capacity.

This adaptability is essential for maximizing resource use and responding to shifting traffic patterns.

Enhanced Service Level Agreements (SLAs)

Hubbing makes it easier for connected operators to build strong service level agreements (SLAs) that guarantee predetermined performance benchmarks and service levels. A telecom environment that is more dependable and predictable, benefits from having clear SLAs.

Facilitation of Innovation Ecosystems

In order to create and implement cutting-edge services and technology, telecom providers might work together in hubs that act as innovation ecosystems. Collaborative research and development projects may hasten the release of novel solutions into the market.

Sustainability Initiatives

Because shared infrastructure in hubbing lowers the total carbon footprint associated with telecom network expansion, it may help promote environmental sustainability. Together, operators may invest in environmentally beneficial practices and technology.

Rapid Adoption of Emerging Technologies

Centralized hubs provide an environment that is favorable for the rapid integration of cutting-edge technologies, like blockchain, AI, and machine learning, across linked networks. This quickens the process of incorporating cutting-edge features and functionalities into telecom services.

Streamlined Interconnection Processes

Hubbing minimizes administrative complexity and shortens the time needed for network integration by streamlining the interconnection procedures between telecom carriers. Having standardized interfaces makes interconnection easier to manage.

Customer Experience Enhancement

Hubbing's collaborative nature facilitates the pooling of knowledge, best practices, and consumer feedback to enhance the customer experience collectively. A customer-centric strategy has the potential to increase satisfaction.

Adaptability to Regulatory Changes

A hubbing model allows telecom operators to respond to regulatory framework changes more quickly since pooled resources and teamwork make compliance modifications easier. Maintaining compliance with regulatory agencies requires proactive participation.

Diverse Revenue Streams

Hubbing gives operators the chance to investigate other income streams in addition to conventional ones, such as hosting outside services or taking part in cross-industry alliances. Diversifying revenue sources helps operators be more financially resilient.

Disadvantages of SMS Hubbing

Complexity of Operations

Operational complexity associated with managing a hubbing environment includes problems with coordination, cross-network troubleshooting, and the need for standard operating procedures. Strong operational frameworks are essential for navigating these kinds of challenges.

Contentions Regarding Resources

In Hubbing architecture, shared resources might result in contentions when operators fight for the same resources during times of high utilization.

Mechanisms for allocating resources effectively are required to stop service quality deterioration.

Restricted Authority over Network Updates

In a centralized hub, operators would have little control over when and how network updates are implemented, which might affect the introduction of new services and technologies. Addressing these constraints requires cooperation and negotiation.

Complicated Systems of Billing and Settlement

In a hubbing model, billing and settlement procedures become more complicated, especially when working with many operators and a range of service offers. Transparent financial transactions depend on well-defined revenue-sharing agreements and automated invoicing systems.

Reliance on the Hub Operator

Operators may rely too much on the hub operator for essential services, which might give rise to conflicts of interest and issues with fair competition.

It is important to establish unambiguous governance frameworks and conflict resolution processes.

Inherent Latency

Real-time applications and services may be impacted by the inherent delay in data transfer caused by Hubbing's centralized structure. In order to reduce latency, technology breakthroughs and ongoing optimization are required.

Restrictions on Network Architecture Flexibility

Hubbing could make it more difficult for individual operators to create and deploy distinctive network designs that are suited to particular consumer needs. One of the main challenges is balancing customization with standardization.

Risks of Market Saturation

Hubbing's collaborative nature raises the possibility of market saturation, in which many operators serve the same subscriber base with comparable services. Strategies of differentiation are necessary to prevent fierce rivalry.

Difficulties with Quality Control

Sustaining uniform service quality over linked networks requires strict quality control procedures, testing, and ongoing observation. To tackle this issue, standardised quality standards might be useful.

Organisational and Cultural Misalignments

Goals and tactics may not coincide when operators from various areas have distinct organizational cultures and business practices.

Establishing a culture of collaboration is essential to the accomplishment of hubbing projects.

Applications of SMS Hubbing
