In general, it is possible to identify eight main functional areas, which are addressed in the ETSI BSM architecture ... |
648692b32393c411cac073882fd20d74 | 103 275 | 4.2 Structure of the present document | The remainder of the present document is structured as follows: • Clause 5 gives the essentials of the BSM architecture along with the overview of the standardized SI-SAP interface service primitives. Missing services and update of current ones are identified, in order to properly update the set of the SI-SAP interface... |
648692b32393c411cac073882fd20d74 | 103 275 | 5 ETSI BSM architecture | |
648692b32393c411cac073882fd20d74 | 103 275 | 5.1 General | The aim of clause 5 is to briefly summarize the primitives that the SI-SAP interface implements towards the underlying protocol layers and the service that are therein supported. Finally, this clause outlines the services that the SI-SAP interface is actually not providing and those that are not properly defined. For t... |
648692b32393c411cac073882fd20d74 | 103 275 | 5.2 Architecture definition | The ETSI BSM architecture ETSI TS 102 292 [1] is superimposed to a general satellite network composed of satellite terminals, gateway, satellite, Network Management Centre (NMC) and Network Control Centre (NCC). The architecture comprises three main elements (depicted in Figure 5.1): • BSM Subnetwork. It is the set con... |
648692b32393c411cac073882fd20d74 | 103 275 | 5.3 Services | The SI-SAP interface provides services pertaining to: • User plane (U-plane). • Control plane (C-plane). • Management plane (M-plane). Being the services defined in the three planes completely independent, it is actually possible to see the SI-SAP interface as decomposed in three independent interfaces: • SI-U-SAP. • S... |
648692b32393c411cac073882fd20d74 | 103 275 | 5.4 SI-SAP interface | The SI-SAP interface defines primitives to be exchanged between the SI and SD layers, in order to support U- and C- plane functionalities. M-plane functionalities are no supported by specific SI-SAP interface service primitives, as management functions are segregated in specific protocol layers, with no interaction bet... |
648692b32393c411cac073882fd20d74 | 103 275 | 5.5 Defined SI-SAP interface service primitives | According to the services provided by the SD layer to the SI layer through the SI-SAP interfaces, the SI-SAP interface service primitives currently defined are as in Table 5.1, where each primitive is denoted as Layer-Plane- PrimitiveName-PrimitiveSemantics, where: • Layer: It is the N+1 layer requesting a given servic... |
648692b32393c411cac073882fd20d74 | 103 275 | 5.6 Update of SI-SAP interface service primitives | In addition to the services discussed in the former clause (i.e. data transfer, resource reservation, group receive and address resolution), three new services shall be also considered to complete the set of functions provided in satellite networks: • Logon/logoff. These services are provided by the SD layer (lower lay... |
648692b32393c411cac073882fd20d74 | 103 275 | 6 SI-SAP interface service primitives | |
648692b32393c411cac073882fd20d74 | 103 275 | 6.1 General | Clause 6 addresses the specification of the new services (logon, logoff, SI layer configuration, and group transmit) along with the related primitives and the update of the primitives of the data transfer service. ETSI ETSI TS 103 275 V1.1.1 (2015-05) 19 |
648692b32393c411cac073882fd20d74 | 103 275 | 6.2 Logon | |
648692b32393c411cac073882fd20d74 | 103 275 | 6.2.1 Service definition | The logon service is carried out by the SD layer to notify the SI layer about the accomplished logon procedure. The logon service is carried out in consequence of the following event: • The ST enters the satellite network by exchanging the SD-dependent control message with the gateway, in order to log on and synchroniz... |
648692b32393c411cac073882fd20d74 | 103 275 | 6.2.2 Primitives involved in the service | The logon service shall use a single primitive: • SI-C-LOGON-IND. |
648692b32393c411cac073882fd20d74 | 103 275 | 6.2.3 Parameters | The service primitive calls the following parameters: • BSM_ID. It is the BSM Identity of the local SI-SAP interface. • Hardware Address. It is the hardware address (i.e. the 48-bit MAC address) of the ST that has initiated the service. |
648692b32393c411cac073882fd20d74 | 103 275 | 6.2.4 Service primitive: SI-C-LOGON | |

648692b32393c411cac073882fd20d74 | 103 275 | 6.2.4.2 SI-C-LOGON-IND | The logon message primitive is an unsolicited indication from the SD layer to the SI layer, to inform the SI layer about the completed logon procedures. Upon primitive receipt, the SI layer shall request the SI layer configuration service from the SD layer. |
648692b32393c411cac073882fd20d74 | 103 275 | 6.3 Logoff | |
648692b32393c411cac073882fd20d74 | 103 275 | 6.3.1 Service definition | The logoff service is provided by the SD layer to inform the SI layer that a logoff procedure has been initiated. The procedure can be triggered within the BSM network (ST or gateway) or in the BSM system (NCC or NMC) but outside the BSM network. ETSI ETSI TS 103 275 V1.1.1 (2015-05) 20 The logoff service is carried ou... |
648692b32393c411cac073882fd20d74 | 103 275 | 6.3.2 Primitives involved in the service | The logoff service shall use a single primitive: • SI-C-LOGOFF-IND. |
