This is particularly relevant in mobile communications where users are constantly on the move. 

• Location-Based Call Routing: DLR dynamically routes calls to a mobile subscriber based on their current geographic location, rather than routing based on the subscriber's home location. This ensures that calls are delivered more efficiently and reliably.

• Reduces Costs and Improves Efficiency: By routing calls based on the current location, DLR reduces the need for calls to be routed over long distances or through multiple networks, which can reduce costs and improve call quality.

• Use in Mobile Networks: DLR is particularly useful in mobile networks where users frequently move across different network areas or regions. It allows the network to adapt to these changes in real-time.

• Privacy Considerations: The use of DLR involves tracking the location of mobile users, which raises privacy considerations. Hence, it's subject to stringent regulations and standards to protect user privacy.

Dynamic Location Routing represents an advanced approach in telecommunications, leveraging the mobility of users to optimize network efficiency and call quality.
