Abstract
To address the need for a communication unit, a communication infrastructure, and method that shorten call-setup time while still providing the benefit of the QPCH, the present invention provides a communication unit (e.g., 103) that sends a page response before receiving a page message from the communication infrastructure, based on the values of the QPCH indicators. This “preemptive” page response shortens call-setup time. Because several communication units may send page responses before verifying whether they specifically are being paged, the infrastructure (e.g., 108-110) determines which page responses are valid (and processes them further) and which are false (and discards them).
Claims28
A method for a communication unit to shorten call-setup time comprising the steps of:
- receiving, by the communication unit from a communication infrastructure, an indication that the communication infrastructure will transmit a page addressed to at least one communication unit of a group of communication units in a paging slot but that does not indicate specifically which communication unit will be addressed, wherein the communication unit is a member of the group;
- and
- transmitting, by the communication unit to the communication infrastructure, a page response message in response to the indication.
A method for a communication infrastructure to shorten call-setup time, the method comprising the steps of:
- transmitting, by the communication infrastructure, an indication that the communication infrastructure will transmit a page addressed to at least one communication unit of a group of communication units in a paging slot but that does not indicate specifically which communication unit will be addressed;
- receiving, by the communication infrastructure from communication units not addressed, page response messages in response to the indication;
- and
- determining, by the communication infrastructure, that the page response messages are false page responses.
A communication unit comprising:
- a receiver arranged to receive an indication that a communication infrastructure will transmit a page addressed to at least one communication unit of a group of communication units in a paging slot but that does not indicate specifically which communication unit will be addressed, wherein the communication unit is a member of the group;
- a transmitter, coupled to the processor, arranged to transmit a page response message;
- and
- a processor, coupled to the receiver and the transmitter, arranged to instruct the transmitter to transmit the page response message in response to the indication.
A communication infrastructure comprising:
- a base site arranged to transmit an indication that the communication infrastructure will transmit a page addressed to at least one communication unit of a group of communication units in a paging slot but that does not indicate specifically which communication unit will be addressed, arranged to receive page response messages in response to the indication from communication units not addressed, and arranged to determine that the page response messages are false page responses;
- and
- a controller, coupled to the base site, arranged to instruct the base site to transmit the indication.
