Basic Call Processing (Voice) - GSM

 

 

 

This page is based on a call processing sequence between an MS and GSM Network Simulator. The details of the sequence and contents of the messages would differ from those from live network, but I think this would contain all the essential components of the call processing. The value in the "Time(sec.ms)/Memo" column is just for a reference to give you rough timing between each step and the next step. It is not the clean-cut/absolute value.

(This is at very early stages of the whole page that I am planning, so I will have on-going update for a long period).

RR  : Channel Request

 

Channel Request has various functionalities and the one right after power-on is is equivalent to RACH process of UMTS and LTE. Simply put, this message is to tell the network "I want to camp on you, please allocate me a radio resource that I initiate the connection process".

 

The one for the initial registration is as follows. (In good channel condition and in open space, the first Channel Request would reach the NW and get the immdediate Assignement with only one Channel Request. Following is a kind of worst case where the initial channel request fail to decoded by NW or UE fails to decode initial immediate assignements)

 

 

Note : T3126 starts when the last retransmission of 'Channel Request' and it stops when UE gets 'Immediate Assignement'. If UE does not get 'Immediate Assignement' until T3126 expires, UE starts cell reselection.

 

The exact functionality of a channel request is determined by the first 8 bits of its message and the description of the first byte is specified by the following table in 44.018.

 

< 44.018 - Table 9.1.8.1: CHANNEL REQUEST message content >

 

 

RR  : Immediate Assignment

 

Immediate Assignement is the answering message to the initial "Channel Request" explained above. This is to say to MS "OK, I will accept your 'channel request' and here goes the radio resource you can use for the following steps".

 

One of the Channel Request example would be as follows. The most important thing you have to notice is that Immediate Assignment should play back the whole Channel Request message. All MS(UE) trying to connect a cell would receive the same 'Immediate Assignement', but if the 'Channel Request' portion contained in 'Immediate Assignement' does not match the Channel Request Bytes it sent, UE should discard the Immediate Assignement message since it is not for itself.
