28、 15.0.0 Release 150 Scope The present document describes the Supplementary Services belonging to the group Call Completion Supplementary Services. The general aspects, including definitions and recommended provision, of the description of Supplementary Services are given in specification TS 22.004 2

29、. The group of Call Completion Supplementary Services is divided into the following two Supplementary Services: - Call waiting (clause 1); - Call hold (clause 2). 0.1 References The following documents contain provisions which, through reference in this text, constitute provisions of the present doc

30、ument. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (inclu

31、ding a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TR 21.905: “Vocabulary for 3GPP Specifications“. 2 3GPP TS 22.004: “General on Supplementary Services“. 3 3GPP TS 22.030: “Man-Machine Interface

33、 in the present document are listed in TR 21.905 1. 1 Call Waiting (CW) 1.1 Definition The Call Waiting Service permits a mobile subscriber to be notified of an incoming call (as per basic call procedures) whilst the traffic channel is not available for the incoming call and the mobile subscriber is

34、 engaged in an active or held call. Subsequently, the subscriber can either accept, reject, or ignore the incoming call. 1.2 Description 1.2.1 Description This service operates when the traffic channel at the controlling subscriber B is not available and B is engaged in an active or held call. ETSI

35、ETSI TS 122 083 V15.0.0 (2018-07)73GPP TS 22.083 version 15.0.0 Release 15When a third party (calling subscriber C) attempts to connect to that termination, the controlling subscriber B is given an appropriate indication of the waiting call. A notification that the call is waiting will be sent back

36、towards the calling subscriber C. The maximum number of waiting calls at one time per mobile access is one. This means that no further calls are offered to the subscriber while a call is waiting. NOTE: As a network option this maximum number of waiting calls may be greater than one. This is consider

37、ed as a possible future enhancement. 1.2.2 Applicability to telecommunication services The applicability of this Supplementary Service to the ongoing call is defined in TS 22.004 2. The incoming, waiting, call may be of any kind. 1.2.3 Terminology (Controlling) subscriber B This is the subscriber wh

38、o is provided by the network with the Call Waiting Service and who reacts to the Call Waiting. Subscriber C This is the subscriber who has originated a call to B which causes the Call Waiting Service to be invoked. Subscriber A This represents a subscriber who is engaged in a call with B, being eith

39、er the calling or the called party. T2; No answer time out The duration of this time out is the time the network will wait for a response from subscriber B, to the offered call from subscriber C. The value of the timer is between 0.5 and 2 minutes at the service providers discretion. 1.3 Normal proc

40、edures with successful outcome 1.3.1 Provision This Supplementary Service is provisioned for all Basic Services (BS) subscribed to and to which it is applicable, i.e. not provisioned to any subset of these BS. 1.3.2 Withdrawal Withdrawal will be at the request of the subscriber or for administrative

41、 reasons. 1.3.5 Activation This Supplementary Service will be activated either collectively for all applicable Basic Services or on a Basic Service group basis by the subscriber using a control procedure, as specified in TS 22.030 3, or by the service provider. The controlling subscriber shall be in

42、formed by the network of the success or otherwise of her action. 1.3.6 Deactivation The service will be deactivated either collectively for all applicable Basic Services or on a Basic Service group basis by the subscriber using a control procedure, as specified in TS 22.030 3, or by the service prov

43、ider. The controlling subscriber shall be informed by the network of the success or otherwise of her action. 1.3.7 Invocation This service is invoked by the network on arrival of an incoming call if the service is active and the controlling subscriber Bs traffic channel is not available, B is engage

44、d in an active or held call and there is no other call currently waiting. ETSI ETSI TS 122 083 V15.0.0 (2018-07)83GPP TS 22.083 version 15.0.0 Release 151.3.8 Normal operation with successful outcome 1.3.8.1 Incoming call from C When an incoming call from subscriber C arrives, the served mobile subs

45、criber is connected to - at least - one call (active or held) and a NDUB (Network Determined User Busy) condition does not exist, then the CW service shall be invoked and the call shall be offered to subscriber B with an appropriate indication, e.g. with a “Call Waiting Tone“. If a response to the o

46、ffered call is received from the mobile termination at B, then the subscriber C shall be given an indication (e.g. ringing tone) that the called subscriber is being informed of the incoming call and, if possible, that call waiting is in operation. 1.3.8.2 Terminating call by A or B If either subscri

47、ber A or subscriber B requests that the call is terminated, then this call shall be terminated as for basic call (see TS 22.030 3 for more information). Subscriber B shall then be given the normal notification that there is a new call to her, as for a normal terminating call. The network shall conti

48、nue to indicate; e.g. ringing tone towards subscriber C as for a normal call. B can then accept the call from C before the expiry of T2. Subscriber B can also free resources by using the Call Hold Supplementary Service. Subscriber B shall then be able to accept the waiting call from subscriber C bef

49、ore the expiry of T2. Alternatively, subscriber B may specifically request release or hold of the connection to A and accept the waiting call as one action (see TS 22.030 3). In this case, the network connects subscriber B to subscriber C with no further notifications to either subscriber. This must be done before the expiry of T2. 1.3.11 Interrogation Status check The controlling subscriber may interrogate the network by the use of a control procedure, as specified in TS 22.030 3. The network shall respond with an appropriate indication tell
