This TS gives the stage 3 description of the Completion of Calls to Busy Subscriber (CCBS) supplementary service within the 3GPP system. The
19、 contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of this TS, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Vers

21、s incremented when editorial only changes have been incorporated in the specification; ETSI ETSI TS 124 093 V13.0.0 (2016-01)53GPP TS 24.093 version 13.0.0 Release 131 Scope The present dcoument gives the stage 3 description of the Completion of Calls to Busy Subscriber (CCBS) supplementary service.
22、 The present document specifies the procedures used at the radio interface (Reference point Um as defined in 3GPP TS 24.002) for normal operation, activation, deactivation, invocation and interrogation of the completion of calls to busy subscriber supplementary services. Provision and withdrawal of
23、supplementary services is an administrative matter between the mobile subscriber and the service provider and cause no signalling on the radio interface. In 3GPP TS 24.010 the general aspects of the specification of supplementary services at the layer 3 radio interface are given. 3GPP TS 24.080 spec
24、ifies the formats and coding for the supplementary services. Definitions and descriptions of supplementary services are given in 3GPP TS 22.004, 3GPP TS 22.08x and 3GPP TS 22.09x-series. Technical specification 3GPP TS 22.093 is related specifically to the Completion of Calls to Busy Subscriber supp
25、lementary service. The technical realization of supplementary services is described in technical specifications 3GPP TS 23.011, 3GPP TS 23.08x and 3GPP TS 23.09x-series. 3GPP TS 23.093 is related specifically to Completion of Calls to Busy Subscriber supplementary service. The procedures for Call Co
26、ntrol, Mobility Management and Radio Resource management at the layer 3 radio interface are defined in 3GPP TS 24.007 and 3GPP TS 24.008. The following supplementary services belong to the call completion supplementary services and are described in the present document: - Completion of Calls to Busy
27、 Subscriber (CCBS) (see clause 4). 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. F

33、urposes of the present document the following definitions apply. Subscriber A: The user of MS A, requesting CCBS. Destination B: The entity addressed in the original call set up, which is busy when first called by subscriber A. 3.2 Abbreviations For the purposes of the present document the following
34、 abbreviations apply: CCBS Completion of Calls to Busy Subscriber MS A Mobile Station of subscriber A NDUB Network Determined User Busy Further related abbreviations are given in 3GPP TR 21.905 ETSI ETSI TS 124 093 V13.0.0 (2016-01)73GPP TS 24.093 version 13.0.0 Release 134 General 4.1 Overview CCBS
35、 allows a calling subscriber A, encountering a Network Determined User Busy (NDUB) called destination B, to be notified when destination B is idle and to have the network reinitiate the call to destination B, if subscriber A desires. All of the radio signalling specific to CCBS is at the subscriber
36、A-side. Each procedure is described in turn. There is no radio signalling specific to CCBS at destination B-side. The radio signalling on the destination B-side uses basic call signalling procedures only. A mobile station that supports CCBS shall support the requirements of the following options use
37、d in 3GPP TS 24.008: 1) Prolonged Clearing Procedure; 2) Network Initiated Mobile Originated Connection Management (MO CM) Connection Request; 3) Network initiated MO call. A network supporting CCBS shall support the requirements of the following options used in 3GPP TS 24.008: 1) CCBS Request activ
38、ation; and 2) Network initiated MO call. 4.2 Activation When CCBS is allowed the network shall give subscriber A the option of activating a CCBS Request. The network shall send a DISCONNECT message to MS A (cause #17 (User Busy) or cause #34 (no circuit / channel available) with diagnostic field ind
39、icating CCBS is Possible and allowed actions indicating CCBS is Possible. The network starts the retention timer T1 when it sends the DISCONNECT message. The MS shall not release the connection with the network if allowed actions is present. If subscriber A attempts to activate a CCBS Request, MS A
40、shall send a RELEASE message, with the Facility information element indicating CCBSRequest and the network shall stop T1. If the subscriber A does not accept CCBS activation, the MS shall send normal RELEASE message and the network shall stop T1 and continue normal call clearing. If the timer T1 exp
41、ires before the RELEASE message is received from the MS, the network shall continue normal call clearing. If the network accepts the activation attempt, it shall acknowledge it by sending a RELEASE COMPLETE message containing the Facility information element with the CCBS index and optionally the Ad
42、dressOfB, SubAddressOfB and the BasicServiceCode. If the network rejects the activation attempt, it shall send a RELEASE COMPLETE message containing the Facility information element with a return error indication. If a TCH has been allocated for the initial call and there are no further need for thi
43、s channel configuration, the network may reconfigure the ongoing connection from TCH(s) mode to SDCCH only mode while waiting for further user input activity. It is a network option to maintain the ongoing connection in TCH mode while waiting for further user input activity. SS Version Indicator val
44、ue 3 or above has to be used.
