A.S00-0v.0 Active Handoff (MC- to MC- and DS- to DS-): the following types of handoffs are supported: Type of Handoff Voice calls Async Data and G Fax Packet Data Calls (up to Mbps) ISDN Interworking Calls Intra-BS, Intra-MSC Soft Handoff Yes Yes Yes Yes f * Intra-BS, Intra-MSC Hard Handoff Yes Yes Yes Yes f Inter-BS, Intra-MSC Soft Handoff Yes Yes Yes Yes f * Inter-BS, Intra-MSC Hard Handoff Yes Yes Yes a Yes f Inter-BS, Inter-MSC Soft Handoff Yes Yes Yes Yes f * Inter-BS, Inter-MSC Hard Handoff Yes No Yes b Yes f Intergenerational Handoff c Yes Yes Yes d No f 0 0 Active Handoff (DS- hard handoff to/from MC-): the following types of handoffs are supported: Type of Handoff Voice calls Async Data and G Fax Packet Data Calls (up to Mbps) * Inter-BS, Intra-MSC Hard Handoff Yes Yes Yes b * Inter-BS, Inter-MSC Hard Handoff Yes No Yes e * Hard handoff does not apply to supplemental channels a. Inter-BS, Intra-MSC Hard Handoff may result in handoff across PDSN boundaries. b. Inter-BS, Inter-MSC Hard Handoff may result in handoff across PDSN boundaries. In addition, this requires extensions to ANSI- for packet data services. c. Intergenerational handoff describes handoff of a mobile between a system that supports packet data service as specified in [] to [0] and a system that supports a packet data service as specified in []. d. Service Option will change in this scenario. e. Inter-BS, Intra-PDSN Dormant Handoff may result in handoff across MSC boundaries. f. Not applicable for DS- to DS- handoffs. Soft Handoff enhancements, as specified in [] are supported by this specification. Access Handoff, Access Probe Handoff and CDMA Channel Assignment into Soft Handoff and Access Entry Handoff as specified in [] are supported in this specification. Access Entry Handoff is transparent to this standard. Mobile-Assisted CDMA-to-CDMA Inter-Frequency Handoff Enhancement is supported as specified in []. Section
A.S00-0v.0 Circuit mode voice service assumptions: The following assumptions are made: 0 0 All mobiles will be capable of executing a service option change and a hard handoff simultaneously. That is, the Action Time for both of these activities may be the same. For inter-vendor hard handoff, the source BS knows the service option capabilities of the target BS. For inter-vendor soft handoff, all target BS channel elements are capable of supporting both the K and EVRC service options (i.e., rate set and rate set ). The source BS may assume that sufficient resources will be available at the target BS for the requested service option. A default service configuration shall be used at all target BSs for hard handoff. The MSC is aware of the service options supported by each of the BSs attached to it. Hard handoff from K to EVRC is disallowed for TIA/EIA/IS-B mobiles. For IS-000 mobiles, if the target BS does not have K available, the target BS may send a new service option to the source BS. Currently, only K (000H and 00H) and EVRC voice service options are supported. The default service option for IOS networks is K voice (SO=000H). All mobile stations capable of supporting EVRC can also support K (000H) service options. The service negotiation will be between the Base Station and the Mobile Station. The service negotiation will only depend on the capabilities of the Base Station and of the Mobile Station. 0 Based on these assumptions, a source BS will always know what vocoder types (EVRC / K) are available at the target BS, and what service configuration is to be used at the target BS. If a change of vocoder type is necessary, the source BS can accomplish it by commanding the MS to execute a service option change and a hard handoff simultaneously. Thus, service negotiation messaging is not needed on either the A or A interfaces. The following procedures are to be followed: 0 If the BS receives a Paging Request from the MSC specifying a service option valid for this version of the IOS but not supported by the BS, the BS will page the mobile with the service option in the Paging Request message. If the BS receives an Origination Message / Paging Response Message from a mobile station specifying a voice service option not valid for this standard, the BS will deny the request. In the case of an originating call, the BS will order the mobile station to generate a local Reorder signal. Otherwise, if the BS receives an Origination Message / Paging Response Message from a mobile station specifying a supported service option (i.e., rate set or rate set ), that is not supported on the particular BS, the BS shall send a CM Service Request message / Paging Response message to the MSC containing the service option received from the mobile station. The MSC will send the service option that was received in the CM Service Request / Paging Response message in the Assignment Request message. Section
A.S00-0v.0 Otherwise, the call is handled using the call setup procedures of this specification. In all cases, if a call is successfully set up, the BS shall inform the MSC of the agreed service option in the Assignment Complete message.

Definitions TBD 0. Call Processing and Supplementary Services Assumptions This section contains assumptions for call processing and supplementary services. In some of the call processing and services functions, it is possible that an inter-bs hard handoff may occur during the process. In such an event, the target BS (i.e., the BS to which the MS has been handed off) shall assume responsibility for functionality ascribed to the BS as defined herein. For example, if an inter-bs hard handoff occurs during a mobile terminated call setup while the MS is in the Waiting for Answer state, the new serving BS shall send a Connect message to the MSC upon receipt of the Connect Order message on the air interface even though that BS was not involved with previous portions of the call setup process... Call Control Call control shall be primarily the responsibility of the MSC. The BS provides message transmission and inter-working between the particular air interface and the MSC.... Terrestrial Circuit Allocation Terrestrial Circuit allocation is handled in the following manner: Section
A.S00-0v.0 The MSC considers the interface to the BS as a route of n circuits. The MSC shall therefore ensure that the terrestrial circuit chosen is able to support the type of call involved. The BS may suggest a preferred terrestrial circuit to the MSC, in which case, the MSC shall use the suggested terrestrial circuit if available. See section. for the definition of available.... Radio Channel Allocation The BS may choose the radio channel to be used on the appropriate cell in the case of multi-cell BSs. This may be based on information received from the MSC. 0... Traffic Channel Release The release of a dedicated resource is primarily controlled by the MSC. However, for radio propagation reasons, the BS can request that the MSC release a call.. Radio Resource Management Assumptions This section contains assumptions about radio resource management... Radio Channel Supervision... Traffic Channel Radio Link Supervision Radio link supervision of dedicated radio resources shall be the responsibility of the BS. If communication with the mobile is lost then the BS can request that the call be cleared. 0... Idle Channel Observation The quality of idle radio channels may be measured by the BS... Radio Channel Management... Radio Channel Configuration Management The channel configuration management shall be controlled between the BS and the Operations System (OS) over the O Interface. The BS shall be able to support one cell or multiple cells. The O Interface is beyond the scope of this specification.... Radio Traffic Channel Management... Radio Channel Allocation The BS shall always choose the radio channel to be used. 0... Radio Traffic Channel Release The release of a dedicated radio resource is primarily controlled by the MSC. However, for radio propagation reasons the BS can request of the MSC that a call be released. Section 0
A.S00-0v.0... Radio Traffic Channel Power Control All power control functions shall be performed between the MS and the BS.... Channel Encoding and Decoding The radio channel encoding and decoding, and interleaving shall be performed by the BS. The type of radio channel coding and interleaving is derived from the information in the Assignment Request message from the MSC. Section
A.S00-0v.0.0 Feature Descriptions. A Interface Call Setup for Voice and Circuit Data Calls Call setup is a process where a sequence of messages is used to advance the call to a stable condition where the parties involved may communicate. A call flows for packet data calls are specified in section. of this document. For details on call clearing please refer to section.. 0.. Mobile Originated Voice and Circuit Data Calls The call setup may be a normal call setup, emergency call setup, PACA call setup, packet data call setup, or other supplementary service invocation. If PACA service is requested during call origination the base station can use either a queuing approach or a channel reservation approach for allocating radio resources (see []). The mechanism to reserve channels using the channel reservation approach is not specified in this standard. The call flow for call origination with PACA service using a queuing approach is specified in section..
