Abstract

An enterprise network is disclosed. The enterprise network includes at least one site. The site includes an authorizing unit, an enterprise private branch exchange (PBX), and a plurality of femtocells. After a first femtocell of the plurality of femtocells receives a voice/data signal from an enterprise-authenticated handset and the authorizing unit authorizes the voice/data signal, the first femtocell distinguishes a destination of the voice/data signal and routes the voice/data signal to the destination.

Claims

1. An enterprise network, comprising:

a first site, comprising;

an authorizing unit;

an enterprise private branch exchange (PBX); and

a plurality of femtocells, coupled to the authorizing unit and the enterprise PBX; and

a second site;

wherein after a first femtocell of the plurality of femtocells receives a voice/data signal from a first enterprise-authenticated handset and the authorizing unit authorizes the voice/data signal, the first femtocell distinguishes a destination of the voice/data signal and routes the voice/data signal to the destination, the first site communicates with the second site through an internet/a public data network (PDN), the first site further comprises an enterprise data gateway coupled to the enterprise PBX, if the destination of the voice/data signal is the second site, the first femtocell will route the voice/data signal to the second site through the enterprise PBX, the enterprise data gateway, and the internet/PDN.

2. The enterprise network of claim 1, wherein the second site comprises:

an enterprise private branch exchange (PBX); and

an enterprise data gateway, coupled between the internet/PDN and the enterprise PBX of the second site, when the enterprise data gateway of the second site receives the voice/data signal from the internet/PDN, the enterprise data gateway of the second site routes the voice/data signal to the enterprise PBX of the second site.

3. The enterprise network of claim 2, wherein if the destination of the voice/data signal is an enterprise internal extension station of the second site, the enterprise PBX of the second site will route the voice/data signal to the enterprise internal extension station of the second site.

4. A femtocell applied in a site of an enterprise network, the site comprising an authorizing unit and an enterprise private branch exchange (PBX), the femtocell comprising:

a communicating unit, coupled to the authorizing unit, the communicating unit receiving a voice/data signal from a first enterprise-authenticated handset and transmitting the voice/data signal to the authorizing unit for authorization; and

a distinguishing unit, coupled to the communicating unit, after the voice/data signal is authorized by the authorizing unit, the distinguishing unit distinguishing a destination of the voice/data signal and the communicating unit routing the voice/data signal to the destination,

wherein the enterprise network further comprises a second site, and the first site communicates with the second site through an internet/PDN, the first site further comprises an enterprise data gateway coupled to the enterprise PBX, if the destination of the voice/data signal distinguished by the distinguishing unit is the second site, the communicating unit of the femtocell will route the voice/data signal to the second site through the enterprise PBX, the enterprise data gateway, and the internet/PDN.
