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

21 | 1 | laforge | * late assignment instead of very early assignment #1778 |
22 | 5 | laforge | * A5/3 support #75 (BTS supports it, we just need to enable it based on MS capability) |

||
28 | 3 | laforge | * support for UMTS AKA over GERAN #1711 |
29 | * support of SMS delivery via GPRS #1587 |
||
30 | * support of combined CS/PS attach (2G and 3G) #1599 #1583 |
||
31 | * support of inter-BSC hand-over (after BSC/MSC split) #1609 |
||
32 | 1 | laforge | * support of inter-MSC hand-over (after HLR+AUC externalization) |
33 | * Real A interface (MTP2/MTP3/SCCP) |
||
34 | 6 | msuraev | * Move all media processing (TRAU frames, RTP) to separate MGW daemon, controlled via MGCP |
35 | 3 | laforge | * Local Call, Local Switching #1602 |
36 | * External interface to HLR #1643 |
||
37 | * External interface for USSD #1597 |
||
38 | 5 | laforge | * Generation of accounting/billing data #1596 |
39 | 1 | laforge | |
40 | 3 | laforge | h2. SIP Interface (osmo-sip-connector |
41 | |||
42 | * better VTY #1680 |
||
43 | * create user manual #1684 |
||
44 | * DTMF support |
||
45 | * call hold #1686 |
||
46 | * codec selection #1683 |
||
47 | |||
48 | 1 | laforge | h2. 3G/3.5G related |
49 | |||
50 | 7 | msuraev | * Iu-CS and Iu-PS interface over M3UA (as specified in 3GPP), not just SUA (current implementation) #1595, #1589 |
51 | 1 | laforge | * test/validate mobility between multiple hNodeB/smallcells |
