The Number Pooling feature provides the functional capability to support 1,000-block Number Pooling in the LRN and Global Title Translation (GTT) databases with a routing functionality similar to LNP. To route a call, the originating switch launches an LRN query to obtain the LRN of the called number. The Alcatel 5070 SSG ANSI must determine the LRN, which may require two database lookups: one to determine if a number is ported, and if it is not ported, another to determine if it is pooled.

Application Location Register

In today’s environment, wireless service providers must pace network growth with an increasing number of subscribers and complex services. The Alcatel 5070 SSG ANSI features Application Location Register (ALR) routing, shown in Figure 3, to allow a more efficient usage of multiple HLRs, SMSCs and voicemail/ unified messaging systems.

With ALR routing, the Alcatel 5070 SSG ANSI locates and routes customer service queries to the proper network node, facilitating
