Hello all,
I am trying to get a Positioning Capability Response from a MS by
sending an Positioning Capability Request. I checked ETSI TS 144 031
(v9.2.0) to figure out how to build the package. Only the
"extended-reference" field is mandatory and so I tried to send a package
just with the content of that field. The "extend-reference" consists of
the smlc-code and the transactionID.
By testing I found out that I have to send at least 6 octets. The first
octet is as usual the referenceNumber and to specify the rrlp component.
The last 2 bits of the 3rd octet and the first 4 bits of the 4th octet
are for the smlc-code. The rest of the 4th octet, the full 5th octet and
the first 6 bits of the 6th octet are for the transactionID.
Furthermore the first 3 bits of the second octet are for the choice
extension. Anyway I have no clue what the meaning is of the last 6 bits
of the 2nd octet and the first 6 bits of the 3rd octet although it seems
like that the 4th bit of the second octet is an extension bit.
However if I send a package I always get "Meassage too short" error.
Adding octets does not help.
Anyone has ever got a Positioning Capability Response for a Request? If
yes I would really appreciate if that someone would share this Request
with me.
Wireshark always shows me that I have sent a Positioning Capability
Request but the Response never comes but the error message. RRLP is
implemented in the phone since I get responses for a Measure Position
Request.
I think by now I have sent around 500 packages :) One example I am using
is: 0x30 0x0E 0x00 0xFF 0xA2 0x04
Best,
Andreas
