Abstract

A personal communication network distribution system includes a predetermined number of node devices, a controller, and a network connecting the controller to each of the node devices. The network carries a time division multiplexed signal having a plurality of channels for carrying digital communication information signals between the controller and the respective node devices. Each respective node device is assigned a respective predetermined number of the plurality of channels for receiving digital communication information signals from and/or for inserting digital communication information signals into the time division multiplexed signal. The time division multiplexed signal also includes a second predetermined number of non-assigned channels. The controller assigns one of the non-assigned channels of the time division multiplexed signal to one of the node devices for receiving and/or for inserting communication information signals into the time division multiplexed signal based on call activity at the one node device.

Claims

1. A method for dynamically allocating a plurality of time division multiplexed channels of a digital signal in a wired ring communications network having a base station controller and a predetermined number of node devices receiving and inserting digital communication information across the network, comprising the base station controller performing the steps of:

(1) communicating over the wired ring communications network with the node devices via the plurality of time division multiplexed channels of the digital signal;

(2) assigning each respective node device a first number of the plurality of time division multiplexed channels of the digital signal;

(3) allocating a second number of the plurality of time division multiplexed channels of the digital signal as floating channels; and

(4) allocating dynamically said floating channels to the respective node devices according to an allocation scheme.

2. The method of claim 1, wherein said step (4) comprises the step of determining whether said allocating dynamically of said floating channels is required.

3. The method of claim 1, wherein said allocation scheme includes at least one criterion from the following group of criteria:

(i) time of day;

(ii) call activity;

(iii) speech interpolation; and

(iv) weighted combination of call activity and time of day.

4. The method of claim 1, wherein the digital signal is implemented as a T-1 signal.

5. A system for dynamically allocating a plurality of time division multiplexed channels of a digital signal, comprising:

a wired ring communications network;

a base station controller coupled to said wired ring communications network; and

a predetermined number of node devices receiving and inserting digital communication information across said wired ring communications network, wherein said base station controller includes;

a communicating means for communicating with the node devices via the plurality of time division multiplexed channels of the digital signal;

an assigning means for assigning each respective node device a first number of the plurality of time division multiplexed channels of the digital signal;

first allocating means for allocating a second number of the plurality of time division multiplexed channels of the digital signal as floating channels; and

second allocating means for allocating dynamically said floating channels to the respective node devices according to an allocation scheme.

6. The system of claim 5, wherein said second allocating means comprises means for determining whether said allocating dynamically of said floating channels according to an allocation scheme is required.

7. The system of claim 5, wherein said allocation scheme includes at least one criterion from the following group of criteria:

(i) time of day;

(ii) call activity;

(iii) speech interpolation; and

(iv) weighted combination of call activity and time of day.

8. The system of claim 5, wherein the digital signal is implemented as a T-1 signal.

9. A method for dynamically allocating twenty-four time division multiplexed (TDM) channels of a T-1 signal in a wired ring communications network having a base station controller (BSC) and a predetermined number of base transceiver stations (BTSs) receiving and inserting digital communication information across the network, comprising the BSC performing the steps of:

(1) communicating with the BTSs via the twenty-four TDM channels of the T-1 signal over the wired ring communications network;

(2) assigning a first number of the twenty-four TDM channels of the T-1 signal to each of the respective BTSs;

(3) allocating a second number of the twenty-four TDM channels of the T-1 signal as floating channels; and

(4) allocating dynamically said floating channels to the respective BTSs according to an allocation scheme.

10. The method of claim 9, wherein said allocation scheme includes at least one criterion from the following group of criteria:

(i) time of day;

(ii) call activity;

(iii) speech interpolation; and

(iv) weighted combination of call activity and time of day.
