patch: fix of paging result issue

[Andreas.Eversberg]

hi,

one of my nokia phones 6310i:

V 04.20
04-03-02
NPE-4
(c) NPM.

when the subscriber is paged, the phone will answer with
"CHREQ_T_PAG_R_ANY" value (ra=0x83). because the phone does not tell use
what it wants, i must assume that there may be a need for a traffic
channel. without this patch, the call will be made with wrong channel
type:

<0200> paging.c:113 Going to send paging commands: imsi:
'262XXXXXXXXXXX' tmsi: '0x3044ea7a'
<0010> abis_rsl.c:1179 Activating ARFCN(121) TS(0) SS(0) lctype SDCCH
chan_nr=0x20 r=PAGING ra=0x83

can we figure out which subscriber did the channel request? if so, we
can check what channel type is required. (we can look through the
transactions and select the required channel type. if a transaction with
higher rate is paging, we can assign this channel type.)

any ideas?

regards,

andreas
