eCore Solution for broadband trunking scenario
The picture below shows a type of networking of the eCore solution applied in broadband trunking scenario. With flexible deployment of different logical NEs, this solution can implement data access, video, trunking communications, and industry-related services.
The eCore solution involves service NEs, such as the CloudUSN and CloudUGW.
CloudUSN
The CloudUSN performs control-plane mobility management, including managing UE contexts and mobility and assigning temporary mobile subscriber identities. The CloudUSN is also built with the HSS function for managing the subscription data and location information of the UEs. The CloudUSN can be regarded as the controller of the LTE network for intra-system updates and handovers and inter-system interoperability.
CloudUGW
The CloudUGW includes the S-GW, P-GW, and MBMS GW.
The S-GW is a user-plane anchor for multiple access networks in 3GPP, and responsible for user-plane data exchange during UE movement between different access systems, screening interfaces of different access networks in 3GPP. The S-GW fulfills gateway functions of the EPC. It terminates interfaces towards the E-UTRAN.
The P-GW is a user-plane anchor between the 3GPP access network and non-3GPP access network. The P-GW connects to the external PDN servers and fulfills gateway functions of the EPC. It terminates the SGi interface connected to the PDN server. A UE can access multiple PDN services through different P-GWs.
The MBMS GW is responsible for transmitting MBMS session control messages to the MME, and forwarding MBMS data to the eNodeB. The MBMS GW can be co-deployed with the P-GW.
