This parameter can

33、be set optionally by the CBC. CTCH Block Set: subset of the transport block set of FACH on which the CTCH used for CBS is mapped uniquely CBS schedule period: finite sequence of CTCH Block Sets of variable length in which scheduled CB messages are broadcast ETSI ETSI TS 125 324 V14.0.0 (2017-04)73GP

36、rotocol RLC Radio Link Control RRC Radio Resource Control UE User Equipment 4 General 4.1 Model of BMC Broadcast/Multicast Control (BMC) is a sublayer of L2 that exists in the User-Plane only. It is located above RLC. The L2/BMC sublayer is assumed as transparent for all services except broadcast/mu

37、lticast. Figure 4.1-1 shows the model of the L2/BMC sublayer within the UTRAN radio interface protocol architecture. At the UTRAN side, the BMC sublayer shall consist of one BMC protocol entity per cell. Each BMC entity requires a single CTCH, which is provided by the MAC sublayer, through the RLC s

38、ublayer. The BMC requests the Unacknowledged Mode service of the RLC. It is assumed that there is a function in the RNC above BMC that resolves the geographical area information of the CB message (or, if applicable, performs evaluation of a cell list) received from the Cell Broadcast Centre (CBC). A

39、 BMC protocol entity serves only those messages at BMC-SAP that are to be broadcast into a specified cell.

40、ions The functions are specified in 2. They are: - Storage of Cell Broadcast Messages. - Traffic volume monitoring and radio resource request for CBS. - Scheduling of BMC messages. - Transmission of BMC messages to UE. - Delivery of Cell Broadcast messages to upper layer (NAS). 6 Services provided t

41、o Upper Layers The BM-SAP provides a broadcast/multicast transmission service in the user plane on the radio interface for common user data in unacknowledged mode. The BMC sublayer interacts with other entities as illustrated in figure 1 of chapter 4. The interactions with the upper layer/U-plane an

42、d the RRC layer are specified in terms of primitives where the primitives represent the logical exchange of information and control between the BMC sublayer and higher layers. They do not specify or constrain implementations. The (adjacent) layers connect to each other through Service Access Points

43、(SAPs). Three types of primitives are used for this document, as follows: - REQUEST: This type is used when a higher layer is requesting a service from a lower layer. ETSI ETSI TS 125 324 V14.0.0 (2017-04)93GPP TS 25.324 version 14.0.0 Release 14- INDICATION: This type is used by a lower layer provi

44、ding a service to notify its higher layer of activities concerning that higher layer. - CONFIRM: This type is used by a lower layer providing the requested service to confirm to the higher layer that the activity has been completed. The primitives defined below are for communications between upper l

45、ayer and BMC, as well as RRC and BMC in the same protocol stack. For the BMC sublayer two sets of primitives are defined. - Primitives between BMC and upper layer (U-plane): BMC - Generic name - Type: Parameters. - Primitives between BMC and the RRC entity: CBMC - Generic name - Type: Parameters. 7

46、Services expected from RLC The BMC uses the unacknowledged mode service of the RLC sublayer. See 1 for details. 8 Elements for layer-to-layer communication 8.1 Service Primitives between RRC and BMC 8.1.1 Primitives The primitives supported at CBMC-SAP between RRC and BMC are shown in Table 8.1.1-1.
