Re: GPRS branch status update

Hi, I gave it a go and got to the ACTIVATE PDP CONTEXT with few hacks : - Changed gsm48_gmm_authorize to make identity requests if it doesn't have everything it needs, and call it from gsm48_rx_gmm_att_req instead of making identity requests directly. - Remove the NM_ATT_IPACC_RLC_CFG_3 attr since my nanoBTS doesn't have EDGE - (and of course, set correct IPs in nanobts_attr_nsvc0 & ipac_gprs_send) The main problem I have currently is that both phones I use (android magic & iPhone 1G), seem to ignore most of the packets that are sent back. So for example, after a GMM ATTACH REQUEST a IDENTITY REQUEST is sent back, and for the first one, the phone answers, then a second IDENTITY REQUEST is sent (need both IMSI & IMEI and the phone did the initial attach request by TMSI ...) and there it's just ignored, no answer. The phone will just retry the ATTACH REQUEST . Same thing with RA LOCATION UPDATE, if I send REJECT with cause=implicit detach, it just retries the RA UPDATE instead of going to ATTACH REQUEST. And the list goes on, the ACTIVATE PDP CONTEXT ACCEPT has to be sent 4-5 times before the phone accept it. Does anyone have a clue what could cause that behavior ? Sylvain
