International Preferred Roaming (IPR)

When a local subscriber roams to another country, this system controls and guides the subscriber to access a preferential subscribed network by simulating the HLR to reject the subscribers location update message that requires for accessing a non-preferential network.

This Network

It identifies the network operated by this carrier. A current network can comprise multiple network types.

Other Network

It identifies the networks operated by other carriers, including national and international networks.

Outbound Roaming

When a subscriber roams out of the country where the subscriber resides, it is called outbound roaming.

Inbound Roaming

When a subscriber roams into the country where this network resides, it is called inbound roaming.

 

Service Advantages:

For Carriers

For carriers, the IPR service has the following advantages:

·         Improving network utilization ratio and increasing operation revenue

·         Improving subscriber loyalty to the network

·         Helping carriers retain long-term and stable cooperation relationship with the carriers of other countries

·         Helping carriers control international roaming traffic and thus increasing international roaming revenue

For subscribers

When a subscriber roams to another country, this system helps the subscriber access a rather preferential network with better QoS based on location change of the subscriber. This ensures the communication quality and decreases the roaming fee for subscribers.
