BBERF  —  Bearer  Binding and  Event  Reporting  Function

[PCC  R8]+

The BBERF acts as a policy enforcement point for bearer binding, uplink bearer binding verification and event reporting to the PCRF when Gxx applies.

This function entity is located at a GW (e.g. S-GW in the 3GPP access with PMIP based S5/S8 case, HSGW in the HRPD case, A-GW in the non-3GPP access when PMIP or DSMIPv6 based mobility is used, ePDG with PMIP based S2b or Untrusted S2c case if Gxb* applies).

The BBERF in the ePDG supports only reporting of the UE's Local IP address and UDP port number to the PCRF. Bearer binding and bearer binding verification functions are not supported.

BD  —  Billing  Domain

[Charging  R6]+

Part of the operator network, which is outside the core network, which receives and processes CDR files from the core network charging functions. It includes functions that can provide billing mediation and billing or other (e.g. statistical) end applications. It is only applicable to offline charging.

BG  —  Border  Gateway

[PLMN  R8]+

The Border Gateway (BG) is a gateway between a PLMN supporting GPRS/EPC and an external inter-PLMN backbone network used to interconnect with other PLMNs also supporting GPRS/EPC. The role of the BG is to provide the appropriate level of security to protect the PLMN and its subscribers.

BGCF  —  Breakout  Gateway  Control  Function

[IMS  R5]+

The BGCF determines the next hop for routing the SIP message. This determination may be based on information received in the signalling protocol, administrative information, and/or database access. For PSTN /CS Domain terminations, the BGCF determines the network in which PSTN/CS Domain breakout is to occur and, within the network where the breakout is to occur, selects the MGCF.

Details are described in TS 23.228.

BM-SC  —  Broadcast-Multicast    Service  Centre

[MBMS  R6]+

The BM-SC provides functions for MBMS user service provisioning and delivery. It may serve as an entry point for content provider MBMS transmissions, used to authorise and initiate MBMS Bearer Services within the PLMN and can be used to schedule and deliver MBMS transmissions.

BPCF  —  Broadband  Policy  Control  Function

[PCC  R11]+

The BPCF is the policy control entity in the Fixed Broadband Access network. The complete specification of the BPCF is defined in BBF TR-134 and BBF TR-203 and it is out of the scope of the 3GPP.

BSC  —  Base  Station  Controller

[GERAN  R96]+

A BSC is a network component in the PLMN with the functions for control of one or more BTS.

BSF  —  Bootstrapping  Server  Function

[GBA  R6]+

A generic Bootstrapping Server Function (BSF) and the UE mutually authenticate using the AKA protocol, and agree on session keys that are afterwards applied between the UE and a Network Application Function (NAF).

BSS  —  Base  Station  System

[GERAN  R96]+

The Base Station System (BSS) is the system of base station equipments (transceivers, controllers, etc.) which is viewed by the MSC through a single A and/or Iu-CS interface as being the entity responsible for communicating with Mobile Stations in a certain area. Similarly, in PLMNs supporting GPRS, the BSS is viewed by the SGSN through a single Gb or Iu-PS interface. When Intra Domain Connection of RAN Nodes to Multiple CN Nodes is applied, a BSS may connect to several MSCs by several A and/or Iu-CS interfaces, and a BSS may connect to several SGSNs by several Gb and/or Iu-PS interfaces. The functionality for the A interface is described in TS 48.002 and for the Gb interface in TS 23.060. The functionality for the Iu-CS interface is described in TS 25.410 and for the Iu-PS interface in TS 23.060.

The radio equipment of a BSS may support one or more cells. A BSS may consist of one or more base stations. Where an Abis-interface is implemented, the BSS consists of one Base Station Controller (BSC) and one or more Base Transceiver Station (BTS). The split of functions between BSS and CN for a Iu interface is described in the 25-series of UMTS Technical Specifications.

The split of functions between BSS and CN for a A/Gb interface is described in the 48-series of GSM Technical Specifications. The split of functions between BSS and CN for a Iu interface is described in the 25-series of UMTS Technical Specifications.

BTS  —  Base  Transceiver  Station

[GERAN  R96]+
