Abstract

A portable phone is equipped with a position detector that detects the geographical position of the portable phone, and a telephone system may ring one or more land-based phones or portable phones according to the geographical position of the portable phone. One or more geographical regions are defined, with corresponding telephone parameters defined for each region. When a portable phone enters a defined region, exits a defined region, or changes between two defined regions, the function of one or more land-based phones or portable phones may change. The preferred embodiments thus allow changing the function of one or more other phones based on the self-detected geographical position of a portable phone. In this manner the convenience of using portable phones is greatly enhanced.

Claims

1. A method for selectively ringing or not ringing a second phone when a call is placed to a portable phone, the method comprising:

(A) the portable phone using an internal position detector to detect its geographical position;

(B) defining at least one geographical region;

(C) defining phone parameters that determine how a call is rung and routed for each defined geographical region;

(D) receiving the position of the portable phone from the position detector;

(E) determining from the received position of the portable phone whether the portable phone enters or exits a defined geographical region;

(F) updating phone parameters for a geographical region when the portable phone enters the geographical region;

(G) updating phone parameters for a geographical region when the portable phone exits the geographical region; and

(H) ringing and routing a telephone call according to the phone parameters for a defined geographical region.

2. The method of claim 1 wherein acts (A), (B), (D) and (E) are performed by the portable phone, and wherein acts (C), (F), (G) and (H) are performed by a telephone network coupled to the portable phone.

3. The method of claim 1 wherein act (A) is performed by the portable phone, and wherein acts (B), (C), (D), (E), (F), (G) and (H) are preformed by a telephone network coupled to the portable phone.

4. A telephone system comprising:

(A) a portable phone that includes a position detector that detects geographical position of the portable phone and reports the detected geographical position of the portable phone to a telephone network;

(B) the telephone network including;

(B1) at least one defined geographical region;

(B2) phone parameters defined for each defined geographical region that determine how a call is rung and routed within the geographical region;

(B3) a mechanism that determines from the reported detected geographical position of the portable phone when the portable phone enters a defined geographical region and when the portable phone exits a defined geographical region;

(B4) a phone parameters update mechanism that updates phone parameters for a geographical region when the portable phone enters a defined geographical region, and that updates phone parameters for a geographical region when the portable phone exits a defined geographical region; and

(B5) a call router that routes a telephone call according to the phone parameters for a defined geographical region.

5. A telephone system comprising:

(A) a portable phone that includes;

(A1) a position detector that detects geographical position of the portable phone;

(A2) at least one named geographical region;

(A3) a message mechanism that sends a message to a telephone network when the portable phone enters a named geographical region and sends a message to the telephone network when the portable phone exits a named geographical region;

(B) a telephone network that includes;

(B1) phone parameters defined for each named geographical region that determine how a call is rung and routed within the named geographical region;

(B2) a phone parameters update mechanism that updates phone parameters for a named geographical region when a message is received from the message mechanism in the portable phone indicating that the portable phone has entered the named geographical region, and that updates phone parameters for a named geographical region when a message is received form the message mechanism in the portable phone indicating that the portable phone has exited the named geographical region; and

(B3) a call router that routes a telephone call according to the phone parameters for a named geographical region.
