eMLPP (Enhanced Multi Level Precedence and Pre emption)

Last updated on 

Introduction

The Enhanced Multi Level Precedence and Pre-emption (eMLPP) is a service provided by a mobile communication system to ensure that high-priority subscribers can always access the network and receive communication services ahead of others. eMLPP is a mechanism for supporting quality of service (QoS) in mobile networks. It provides a means for assigning priorities to mobile subscribers and giving them pre-emption capabilities, allowing them to interrupt lower-priority communication services. This paper provides an in-depth explanation of eMLPP, including its features, benefits, and how it works in a mobile communication system.

Overview of eMLPP

eMLPP is a set of services that are designed to improve the QoS for subscribers in mobile communication systems. The eMLPP service provides subscribers with a mechanism for assigning different levels of priority to their communication services. These priority levels are based on the subscriber's status or the type of communication service being provided. For example, emergency services like police, fire, and ambulance have a higher priority than normal voice or data services. The eMLPP service allows higher priority services to preempt lower priority services, ensuring that they are always available to subscribers.

Features of eMLPP

The eMLPP service has several features that make it an essential service in mobile communication systems. These features include:

  1. Multiple levels of priority: eMLPP supports up to 16 different levels of priority, allowing subscribers to assign different levels of importance to their communication services.
  2. Pre-emption capabilities: eMLPP allows higher priority services to preempt lower priority services, ensuring that subscribers with high-priority services can always access the network.
  3. Flexible assignment of priorities: eMLPP provides a flexible mechanism for assigning priorities to subscribers. Priorities can be based on subscriber status, the type of service being provided, or any other criteria that the network operator deems appropriate.
  4. Call barring: eMLPP provides call barring capabilities to prevent lower priority services from preempting higher priority services. This ensures that high-priority services are always available to subscribers.
  5. Configurable parameters: eMLPP provides configurable parameters that allow network operators to adjust the service to meet the needs of their subscribers.

Benefits of eMLPP

The eMLPP service provides several benefits to subscribers and network operators. These benefits include:

  1. Improved QoS: eMLPP ensures that high-priority services are always available to subscribers, improving the overall QoS of the network.
  2. Increased network efficiency: eMLPP allows network operators to manage network resources more efficiently by ensuring that high-priority services are given access to the network ahead of lower priority services.
  3. Better subscriber experience: eMLPP provides subscribers with a better experience by ensuring that their high-priority services are always available, even during times of high network congestion.
  4. Enhanced emergency services: eMLPP ensures that emergency services like police, fire, and ambulance are always given the highest priority, improving the response time of these critical services.

How eMLPP Works

eMLPP works by assigning different levels of priority to subscribers and their communication services. When a subscriber initiates a communication service, the network checks the priority level of the service and compares it to the priority levels of other services currently being provided on the network. If the priority level of the service is higher than the priority level of any other service, the new service is given access to the network ahead of the lower priority services.

eMLPP also provides pre-emption capabilities, allowing higher priority services to interrupt lower priority services. When a higher priority service requests access to the network, it sends a pre-emption message to the lower priority service, notifying it that it must release the network resources it is currently using. The lower priority service then releases the resources and the higher priority service is given access to the network. The pre-emption message can be sent to multiple lower priority services simultaneously, allowing the higher priority service to access the network quickly and efficiently.

In addition to pre-emption capabilities, eMLPP also provides call barring capabilities. Call barring allows network operators to prevent lower priority services from preempting higher priority services. This is done by assigning call barring parameters to certain services, preventing them from being preempted by other services with lower priority levels.

eMLPP also provides configurable parameters that allow network operators to adjust the service to meet the needs of their subscribers. These parameters can include things like the number of priority levels supported, the pre-emption message that is sent to lower priority services, and the call barring parameters that are assigned to certain services.

eMLPP is typically implemented using a combination of hardware and software in the mobile communication system. The hardware includes switches, routers, and other network components that are used to manage network resources. The software includes the eMLPP service logic that is used to assign priorities to subscribers and manage access to the network.

Conclusion

The eMLPP service is an essential component of modern mobile communication systems. It provides a means for assigning priorities to subscribers and ensuring that high-priority services are always available, even during times of high network congestion. eMLPP provides multiple levels of priority, pre-emption capabilities, call barring capabilities, and configurable parameters that allow network operators to adjust the service to meet the needs of their subscribers. By providing improved QoS, increased network efficiency, better subscriber experience, and enhanced emergency services, eMLPP is a critical service that helps ensure the reliability and effectiveness of mobile communication systems.
