Abstract

A multiple mode, personal, wireless communications system exists within a radiotelephone network serving general customers and provides additional services to a select group of customers. The system uses handsets which automatically switch between a standard cellular radiotelephone mode of operation and an enhanced cordless mode when the handsets are within range of pico cells that are interconnected to the public switched telephone network. Each pico cell is controlled via a framework of overlay cells that operates independently of the radiotelephone network and uses a unique control protocol on a small number of reserved cellular channels. Each pico cell consists of a spectrally dynamic, non-capturing, frequency agile, multi-purpose base station provided at customer-selected locations to cooperate with the overlay cell framework. Each pico cell is capable of supporting multiple handsets and uses low power operation that achieves limited coverage. Each pico cell reduces traffic on the standard cellular radiotelephone network by independently handling registered handsets. An alternate line option module provides wireless local interconnect capability to selectively route call traffic between land lines and the standard cellular radiotelephone network. Service control units and host stations facilitate wireless activation and control of each pico cell and handset via the overlay cell framework.

Claims

1. In a multiple mode communications system, a location analysis process including the steps of:

a) providing radio handsets capable of communicating selectively with cell sites of a cellular radiotelephone network and cordless stations of a local radio network;

b) configuring said cell sites to continuously broadcast data which identify said cell sites;

c) configuring said cordless stations to refrain from continuously broadcasting overhead message data streams;

d) comparing in one of said radio handsets, said data which identify said cell sites with a preselected profile of cell site identity data;

e) generating a trigger signal in response to a match of said data; and

f) transmitting an access request signal from said one radio handset in response to said trigger signal, said access request signal being configured to be received by one of said cordless stations.

2. The process of claim 1, further including the steps of:

periodically repeating transmission of said access request signal from said one radio handset;

receiving a response to said access request signal from one of said cordless stations; and

upon receipt of said response, performing a registration handshake with said one cordless station.

3. The process of claim 2, further including the step of initiating a call forwarding process to send calls for said one handset which are initiated from said cellular network to said one cordless station.

4. The process of claim 3, further including the step of switching said one handset to a local communication mode with said one cordless station.

5. The process of claim 1 wherein said one handset transmits at a first power level while communicating with one of said cell sites, said process further including the steps of:

registering said one handset for operation on said cordless station in response to said transmitting step; and

reducing the power level of the handset to a level below that at which said one handset communicates with said one of said cell sites.

6. The process of claim 1 further including the steps of:

registering said one handset for operation on said cordless station in response to said transmitting step; and

placing, after said registering step, a message on a display of said one handset that indicates to a user that the handset is in a home mode.

7. The process of claim 1, wherein said data which identify said cell sites comprise signaling channel identity and digital color code information.

8. The process of claim 1 additionally comprising the step of refraining from transmitting said access request signal when said trigger signal is absent.

9. In a multimode wireless handset capable of exchanging communications within a telecommunications network in accordance with a cellular mode of operation over a first set of channels and a cordless mode of operation over a second set of channels, means for receiving cellular system identity information and land station identity information over one of said first set of channels;

means, responsive to said system identity information, for selecting a cellular system to monitor while operating in said cellular mode of operation;

means for comparing, while said cellular system remains selected, cellular land station identity information with a profile of stored identity information;

means responsive to said comparing means for signaling a match; and

means, coupled to said signaling means, for transmitting an access request signal from said handset in response to said match, said access request signal being transmitted over one of said second set of channels while said cellular system remains selected.

10. The handset of claim 9 further including means, coupled to said comparing means, for inputting and storing a profile of server identification for said handset.

11. The handset of claim 9 further including means for displaying an appropriate location message on said handset in response to said match.

12. The handset of claim 9 additionally comprising timing means, coupled to said transmitting means, for causing said transmitting means to periodically repeat transmission of said access request signal when said signaling means continues to signal said match.

13. The handset of claim 9, wherein said transmitting means is configured to refrain from transmitting said access request signal when said signaling means does not signal said match.

14. The handset of claim 9, wherein said identity information and said profile of stored identity information comprise signaling channel identity and digital color code information.

15. The handset of claim 9, wherein:

said identity information is broadcast by cellular land stations; and

said transmitting means is configured so that said access request signal is compatible with stations other than said cellular land stations.
