Reply To: GPRS – Channel Request and RSL link


Hi olivier,

the channel required is an abis message –> a vendor can modify quite extensively the 3GPP in order to fit its needs.

For example, in case of an 11-bits access burst (= egprs channel request, with a radom access ref of 11 bits), the RA field is not big enough to carry the whole info (only 8 bits !)

So an optional field at the end of the Channel Required might be used.

It’s vendor dependent.
