Abstract
Abstract In a data communication system (100) including infrastructure (101) arranged to communicate with a plurality of terminals (103) over a channel (109), a method of adaptable registration includes determining a registration status (401), and executing a registration contention procedure adaptable to the registration status (403). A corresponding method of facilitating adaptable registration includes determining a registration contention information (501), the registration contention information corresponding to a contention procedure implemented by the plurality of terminals, and sending a message corresponding to said system registration information (519).

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
77 words
In a data communication system including infrastructure arranged to communicate with a plurality of communication units over a channel, a method of adaptable registration at a communication unit comprising: receiving at least one message indicative of a change in access level and including registration information: determining whether to register based on a current access level and when to register based on the registration information: and sending a registration message after a delay based on the registration information.
Claim 2
Dependent Claim
77 words
In a data communication system including infrastructure arranged to communicate with a plurality of communication units over a channel, a method of adaptable registration at a communication unit comprising: receiving at least one message indicative of a change in access level and including registration information: determining whether to register based on a current access level and when to register based on the registration information: and sending a registration message after a delay based on the registration information.
Claim 3
Dependent Claim
33 words
The method of claim 1 wherein said step of determining when to register comprises, when the at least one message includes a restricted access indicator, determining the delay based on the registration information.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
37 words
The method of claim 2 wherein said step of determining the delay based on the registration information comprises determining the delay based on at least a portion of the registration information corresponding to a delay registration indicator.
Claim 6
Dependent Claim
36 words
The method claim 2 wherein said step of determining the delay based on the registration information comprises determining the delay based on at least a portion of the registration information corresponding to a channel access level.
Claim 7
Dependent Claim
23 words
The method of claim 1 wherein said step of determining when to register comprises determining the delay based on a communication unit priority.
Claim 8
Dependent Claim
28 words
