Osmocom and LTE

+
+ +
+
+
+

Irrespective of Osmocom…

+
+

What do we need to run a combined 2G/4G network?

+
    +
  1. + +shared subscriber database (HLR + HSS) + +
    2. +
  2. + +advertisement of respective neighbor cells + +
    3. +
  3. + +shared PS tunnel endpoint (GGSN + P-GW) + +
    4. +
+

optionally:

+ +
+
+
+

Shared Subscriber Database

+
+ +
+
+
+

Advertisement of neighbor cells

+
+ +
+
+
+

Shared PS tunnel endpoint

+
+ +

Solution:

+ +
+
+
+

SGs interface

+
+ +
+
+
+

Inter-RAT PS handover

+
+ +
+
+
+

Conclusions

+
+

The logical steps to improve our LTE interworking are:

+
    +
  1. + +split HLR/HSS and split GGSN/P-GW (today) + +
    2. +
  2. + +GSUP-to-DIAMETER translator for shared HLR/HSS + +
    3. +
  3. + +shared GGSN/P-GW for + +
    4. +
