The Multi-Operator Core Network (MOCN) is a solution that provides the shared radio access network (RAN).On the traditional network, one RAN is connected to one CN only. In the MOCN networking, the RAN can be connected to multiple CNs.

 

What makes MOCN technically possible is that the RNC in the RAN identifies the home CN of a subscriber by the IMSI-PLMN relationship. With the MOCN function, multiple carriers can share the same RAN and drive down CAPEX.

 

For the 3GPP R6 UE, the MOCN function is implemented through interworking between the UE and the RNC.

 

For the UE earlier than 3GPP R6, the MOCN function is implemented through interworking between the RNC and the CN.

 

In the MOCN networking, a reroute procedure is added between the CN and the RNC to ensure that the UE is connected to only the home PLMN. The reroute procedure is implemented through new information elements (IEs) contained in the original Initial UE message and the Direct Transfer message.

 

 

Implemented node: VMSC

 

Served network: UMTS

 

Service benefits:

 

For carriers:

• Multiple carriers can share the 3G access network, which improves the usage of the radio resources and helps to reduce the CAPEX.
• The networks are shared. At the same time, the CNs can run independently.

 

For subscribers: None

 

Requirements for peripheral network entities:

The RNC must support the MOCN function.

The BSC does not support the MOCN function

 

documentation very useful for my job

Its a totally new concept, thanks for sharing.

With the MOCN function, multiple carriers can share the same RAN and drive down CAPEX.

Its a great idea. We have to discuss with other operator for implementing this.

Why multiple operator core when we can always use the extensive features of the Huawei core products, i believe we need to explore more on what these present huawei core networks can do before deploying a multi-core scenario. One thing i like in Huawei is the responsiveness of the R&D and the support in deploying new solutions at the core network, very appreciative.

It will help my job
