| 1 | 1 | laforge | h1. Overall Roadmap |
|---|---|---|---|
| 2 | |||
| 3 | 3 | laforge | This is the general direction in which we would like the Osmocom |
| 4 | Cellular Infrastructure projects to move. None of this will of course |
||
| 5 | happen |
||
| 6 | 1 | laforge | without significant contribution and/or funding: |
| 7 | |||
| 8 | h2. BTS |
||
| 9 | |||
| 10 | 3 | laforge | * more systematic generation + reporting of alarms over Abis OML #1615 |
| 11 | 4 | laforge | * communication of BTS specific capabilities/features towards BSC (via Abis extension) to avoid BTS/BSC config mismatches #1614 |
| 12 | 1 | laforge | |
| 13 | h2. BSC |
||
| 14 | |||
| 15 | * BSC/MSC split: Real A interface with BSSAP/BSSMAP between MSC and BSC |
||
| 16 | 3 | laforge | * Support of 3GPP A-over-IP in addition to current non-standard IPA |
| 17 | * multiplex / SCCPlite |
||
| 18 | 1 | laforge | * Alarm handling |

| 34 | * support of inter-BSC hand-over (after BSC/MSC split) #1609 |
||
| 35 | 1 | laforge | * support of inter-MSC hand-over (after HLR+AUC externalization) |
| 36 | * Real A interface (MTP2/MTP3/SCCP) |
||
| 37 | 3 | laforge | * Move all media processing (TRAU frames, RTP) to separate MGW daemon, |

| 44 | 3 | laforge | h2. SIP Interface (osmo-sip-connector |
| 45 | |||
| 46 | * better VTY #1680 |
||
| 47 | * create user manual #1684 |
||
| 48 | * DTMF support |
||

| 53 | |||
| 54 | 3 | laforge | * Iu-CS and Iu-PS interface over M3UA (as specified in 3GPP), not just |

| 61 | 1 | laforge | * network with simultaneous 2G and 3G/3.5G cells |
| 62 | |||
| 63 | h2. PCU |
||
| 64 | |||
| 65 | * more complete EGPRS implementation for uplink and downlink |

||
| 70 | 1 | laforge | |
| 71 | h2. Build and Test infrastructure |
||
| 72 | |||
| 73 | * more mature osmo-gsm-tester setup |
||
| 74 | 3 | laforge | ** have osmo-gsm-tester do full end-to-end regression testing on every |
| 75 | commit or every night |
||
| 76 | ** develop test cases for MO-Call, MT-Call, Hold/Retrieve, USSD, |
||
| 77 | SMS-in-Call, hand-over, etc. |
||
| 78 | ** not only functional testing, but performance testing (time to deliver |
||
| 79 | N SMS) |
||
| 80 | 1 | laforge | ** GPRS/EGPRS testing |
| 81 | 3 | laforge | *** (single-MS ul/dl throughput, multi-MS ul/dl throughput) #1544 |

| 84 | protocol stack) |
||
| 85 | 1 | laforge | |
| 86 | h2. Libraries/Infrastructure |
||
| 87 | |||
| 88 | 5 | laforge | * VTYv2: Externalize VTY + config management #1601 #1613 #1600 |
| 89 | 3 | laforge | ** shared daemon that manages a MIB and offers VTY + control interface |
| 90 | to access that MIB |
||
| 91 | ** individual programs just access that config daemon via well-defined |
||
| 92 | API |
||
| 93 | 1 | laforge | ** preferably with transactions, roll-back |
| 94 | ** avoid hand-written code for parsing individual VTY commands |
||
| 95 | ** avoid duplicate code for VTY + Control interface |
||
| 96 | 3 | laforge | |
| 97 | h2. Documentation |
||
| 98 | |||
| 99 | * provide one conscise set of tutorials/howto's as opposed to fragmented |
||
| 100 | * and duplicated, outdated information in wiki #1719 |
||
| 101 | * regularly update user manuals and reference manuals |
