Vadim Yanitskiy gerrit-no-reply at lists.osmocom.orgHello Pau Espin Pedrol, Harald Welte, Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/11138 to look at the new patch set (#3). Change subject: trxcon/scheduler: fix Measurement Reporting on SACCH ...................................................................... trxcon/scheduler: fix Measurement Reporting on SACCH According to 3GPP TS 04.08, section 3.4.1, SACCH logical channel accompanies either a traffic or a signaling channel. It has the particularity that continuous transmission must occur in both directions, so on the Uplink direction measurement result messages are sent at each possible occasion when nothing else has to be sent. The LAPDm fill frames (0x01, 0x03, 0x01, 0x2b, ...) are not applicable on SACCH channels! Unfortunately, 3GPP TS 04.08 doesn't clearly state which "else messages" besides Measurement Reports can be send by the MS on SACCH channels. However, in sub-clause 3.4.1 it's stated that the interval between two successive measurement result messages shall not exceed one L2 frame. This change introduces a separate handler for SACCH primitives, which dequeues a SACCH primitive from transmit queue, if present. Otherwise it dequeues a cached Measurement Report (the last received one). Finally, if the cache is empty, a "dummy" measurement report is used. When it's possible, a non-MR primitive is prioritized.
