Chapter 10, TIA/EIA-136 Basics
Basic Functions of the DCCH in TIA/EIA-136
REGID_PER: the number of superframes over which REGID is incremented.
Ranges from 0 to 15 superframes. The value 0 indicates that REGID is not
incremented.
A superframe is 16 TDMA frames = about 640 milliseconds.
Paging
Paging occurs primarily for the base to establish a call with the mobile. However,
with TIA/EIA-136, there are some other types of information the mobile must
respond to.
This is the procedure for responding to a set of specialized page messages.
1. The mobile receives a message indicating a page.
2. The mobile responds with a message appropriate to the type of page sent.
3. The mobile enters the next state appropriate to the type of page.
Some of the pages that the mobile must be able to respond to are listed below.
• Hard Page: the mobile will respond and enter the Waiting for Order state.
• Page with User Group indication: begin User Group procedures.
• Audit Order indicating User Group: if the mobile is part of the proper user group, the
mobile will confirm audit order, and re-register if necessary.
• Confirm audit message and re-register if necessary.
Example: Mobile receives a Hard Page which results in call origination
1. The mobile receives a message indicating a Hard Page.
2. The mobile responds with a Page Response message with a Service Code that indicates
the desired service. Service Code indicates speech type (analog, digital, or both), fax,
or data.
3. The mobile enters the Waiting for Order state.
4. Base station sends a DTC Designation, and the call establishment continues.
