26、083 version 14.0.0 Release 140 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
27、TS 22.004 2. 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
28、present document. 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 docu
29、ment (including 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-Machin

31、ations used 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 su
32、bscriber is engaged in an active or held call. Subsequently, the subscriber can either accept, reject, or ignore the incoming call. ETSI ETSI TS 122 083 V14.0.0 (2017-03)73GPP TS 22.083 version 14.0.0 Release 141.2 Description 1.2.1 Description This service operates when the traffic channel at the c
33、ontrolling subscriber B is not available and B is engaged in an active or held call. When 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
34、 sent back 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
35、is considered 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 su
36、bscriber who 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,
37、 being either 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
38、Normal procedures 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 adm
39、inistrative 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
40、shall be informed by the network of the success or otherwise of her action. ETSI ETSI TS 122 083 V14.0.0 (2017-03)83GPP TS 22.083 version 14.0.0 Release 141.3.6 Deactivation The service will be deactivated either collectively for all applicable Basic Services or on a Basic Service group basis by the
41、 subscriber using a control procedure, as specified in TS 22.030 3, or by the service provider. 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
42、 is active and the controlling subscriber Bs traffic channel is not available, B is engaged in an active or held call and there is no other call currently waiting. 1.3.8 Normal operation with successful outcome 1.3.8.1 Incoming call from C When an incoming call from subscriber C arrives, the served
43、mobile subscriber 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 respon
44、se to the offered 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 eit
45、her subscriber 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
46、shall continue 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 subsc
47、riber C before 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
48、. 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 telling the subscriber whether the service is
49、 supported in this network and, if so, provide a list of all Basic Service groups to which the Call waiting Supplementary Service is active. 1.4 Exceptional procedures or unsuccessful outcome 1.4.1 Incoming call from subscriber C ignored by subscriber B If no response is received by the network from controlling subscriber B before the expiry of T2, then the network shall inform the controlling subscriber B that the call is no longer waiting. Subscriber C shall then be given a no reply indication, unless e.g. Call Forwarding applies. The call
