The general aspects, including definitions an
27、d recommended provision, of the description of Supplementary Services are given in specification 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
28、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. For a specific reference, subsequent revisions do not apply. Fo
29、r a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (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 Spec

32、l procedures) whilst the traffic channel is not available for the incoming call and the mobile subscriber 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 V13.0.0 (2016-01)73GPP TS 22.083 version 13.0.0 Re
33、lease 131.2 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. When a third party (calling subscriber C) attempts to connect to that termination, the controlling subscriber B is giv
34、en an appropriate indication of the waiting call. A notification that the call is waiting will be 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 waiti
35、ng. NOTE: As a network option this maximum number of waiting calls may be greater than one. This 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 incomi
36、ng, waiting, call may be of any kind. 1.2.3 Terminology (Controlling) subscriber B This is the subscriber 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
37、Service to be invoked. Subscriber A This represents a subscriber who is engaged in a call with B, 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
38、 C. The value of the timer is between 0.5 and 2 minutes at the service providers discretion. 1.3 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 su
39、bset of these BS. 1.3.2 Withdrawal Withdrawal will be at the request of the subscriber or for administrative 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 contro
40、l 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. ETSI ETSI TS 122 083 V13.0.0 (2016-01)83GPP TS 22.083 version 13.0.0 Release 131.3.6 Deactivation The service will be deactivat
41、ed 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 informed by the network of the success or otherwise of her action. 1.3.
42、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 engaged in an active or held call and there is no other call currently waiting. 1.3.8 Normal operation with successful
43、outcome 1.3.8.1 Incoming call from C When an incoming call from subscriber C arrives, the served 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 off
44、ered to subscriber B with an appropriate indication, e.g. with a “Call Waiting Tone“. If a response 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 ca
45、ll and, if possible, that call waiting is in operation. 1.3.8.2 Terminating call by A or B If either 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 no
46、rmal notification that there is a new call to her, as for a normal terminating call. The network 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
47、Hold Supplementary Service. Subscriber B shall then be able to accept the waiting call from subscriber 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
48、 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 n
49、etwork shall respond with an appropriate indication telling the subscriber whether the service is 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.
