Signaling procedures required for completing a call may include the following: call setup, call release (including CSFB if it occurs), handover, tracking area update (TAU), DRB setup and release, and transition from the uplink-synchronized state to the uplink-asynchronized state. BHCA indicates the signaling processing capabilities of a system. A busy hour call initiated on different operators' networks involves different types and numbers of signaling procedures and therefore consumes different amount of eNodeB resources. As a result, the BHCA capability varies depending on the traffic model. The BHCA specifications provided by Huawei are based on the smartphone traffic model. The following table lists the signaling specifications of the LMPT, UMPT, LBBP, and UBBP boards in the smartphone traffic model.

This section describes two traffic models: datacard traffic model and smartphone traffic model. The datacard traffic model derives from a typical LTE network where data cards make up a large proportion of all admitted terminals. LTE dongle and customer premises equipment (CPE) are examples of such data cards. UEs in this traffic model are characterized by long online duration, low mobility, and many large-packet data services. The smartphone traffic model derives from a typical LTE network where smartphones make up a large proportion of all admitted terminals. UEs in this traffic model are characterized by short online duration, frequent network access and release, high mobility, and many small-packet data services. The following table describes the control plane (CP) traffic models for the datacard and smartphone traffic models. (1) : Traffic models described in the following table are obtained at busy hours. @BH refers to at busy hour.
