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: Version 3.y.z where: x the first digit: 1 presented to TSG for info

21、d in the specification; ETSI ETSI TS 124 093 V14.0.0 (2017-03)53GPP TS 24.093 version 14.0.0 Release 141 Scope The present dcoument gives the stage 3 description of the Completion of Calls to Busy Subscriber (CCBS) supplementary service. The present document specifies the procedures used at the radi
22、o 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 supplementary services is an administrative matter between the
23、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 specifies the formats and coding for the supplementary services. De
24、finitions 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 supplementary service. The technical realization of supplementary s
25、ervices 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 Control, Mobility Management and Radio Resource management at the
26、 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 Subscriber (CCBS) (see clause 4). 2 References The following d

35、termined 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 A-side. Each procedure is described in turn. There is no
36、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 used in 3GPP TS 24.008: 1) Prolonged Clearing Procedure; 2)
37、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 activation; and 2) Network initiated MO call. 4.2 Activation W
38、hen 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 indicating CCBS is Possible and allowed actions indicating C
39、CBS 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 shall send a RELEASE message, with the Facility informati
40、on 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 expires before the RELEASE message is received from the MS,
41、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 AddressOfB, SubAddressOfB and the BasicServiceCode. If the
42、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 this channel configuration, the network may reconfigure the
43、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 value 3 or above has to be used. ETSI ETSI TS 124 093 V14.0.
