Mobile numbers (MSISDNs) uniquely identify subscribers on a cellular network. Each mobile number corresponds to a user device (via the SIM card) that accesses voice, SMS, and data services. The network tracks traffic based on these identifiers to manage resources and billing.
Although a mobile number itself is just an identifier, the number of active mobile numbers in a given area directly correlates with the number of devices generating traffic, which can contribute to congestion.
2. How Network Congestion Occurs
Network congestion happens when the demand for network resources (radio spectrum, bandwidth, processing capacity) exceeds what the infrastructure can handle, leading to degraded service quality such as dropped calls, slow data speeds, or delayed messages.
Congestion arises mainly due to:
High Subscriber Density: Many mobile numbers active simultaneously in a small area can overload base stations.
High Data Usage: Users generating heavy data traffic (video streaming, downloads) increase network load.
Simultaneous Voice Calls: Many concurrent calls recent mobile phone number data consume circuit-switched or VoIP resources.
Signaling Traffic: Large numbers of mobile devices frequently connecting, disconnecting, or updating location cause signaling congestion.
3. Mobile Numbers and Traffic Patterns
Each mobile number represents an individual subscriber whose usage patterns affect network load:
Peak Hours: When many subscribers (mobile numbers) use the network simultaneously, congestion is more likely.
Event Concentrations: Areas with temporary large gatherings (concerts, sports events) see spikes in active mobile numbers and traffic, leading to local congestion.
Roaming Subscribers: Visitors using their mobile numbers in a network add to total load.
4. Impact of Number Portability and Multiple Numbers
Number Portability: Allows subscribers to retain numbers while changing carriers; this does not affect congestion directly but influences traffic distribution across networks.
Multiple Numbers per User: Some users maintain multiple mobile numbers (e.g., work and personal), increasing active connections and potential traffic.
5. Managing Congestion Related to Mobile Numbers
Network operators use several strategies linked to mobile number activity to manage congestion:
Traffic Prioritization: Operators may prioritize certain types of traffic or subscribers based on policies associated with their mobile number or subscription plan.
Load Balancing: Distributing traffic from mobile numbers across multiple base stations or frequency bands to avoid overload.
Capacity Expansion: Adding more radio cells or spectrum to areas with high density of mobile numbers.
Congestion Controls: Temporarily limiting new connections or data speeds for certain mobile numbers during peak congestion.
6. Role of Mobile Number Tracking in Congestion Control
By tracking activity per mobile number, operators can:
Identify heavy users or problematic devices causing disproportionate congestion.
Analyze usage patterns for network planning and optimization.
Implement fair usage policies linked to mobile numbers to maintain service quality.
Conclusion
Mobile numbers themselves are identifiers, but they represent individual subscribers whose collective usage creates traffic that can lead to network congestion. The number of active mobile numbers in an area directly impacts network load and capacity. Operators monitor mobile number activity to manage congestion through prioritization, capacity planning, and traffic control, ensuring smooth and efficient network performance even during high-demand periods.
