26、n 15.0.0 Release 15Foreword This Technical Specification has been produced by the 3GPP. This TS specifies the stage 1 description of Completion of Calls to Busy Subscriber (CCBS) from the subscribers and users points of view; in particular: - the procedures for normal operation with successful outco
27、me; - the action to be taken in exceptional circumstances; - the interaction with other 3GPP supplementary services. within the 3GPP system. This Technical Specification has been produced by the 3rdGeneration Partnership Project (3GPP). The contents of the present document are subject to continuing
28、work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented

36、of the present document, the following definitions apply: CCBS supplementary service: is a service which enables a calling subscriber A, encountering a NDUB destination B, to have the call completed when the busy destination B becomes idle, without having to make a new call attempt. CCBS busy on the
37、 A side: is caused by the following condition: - while the CCBS recall timer T4 or the CCBS notification timer T10 is running or until the CCBS call is completed or the CCBS call fails. CCBS busy on the B side: is caused by the following conditions: - while the idle guard timer (T8) is running; - wh
38、ile there is CCBS recall pending (i.e. while the CCBS recall timer T9 is running). ETSI ETSI TS 122 093 V15.0.0 (2018-07)73GPP TS 22.093 version 15.0.0 Release 15Subscriber A and Destination B is indicated as idle if there are no active calls, no calls on hold and no call waiting for the subscribers
39、. Subscriber A and Destination B is indicated as not reachable if one of the conditions defined in TS 29.002 4 apply (e.g. IMSI detach, no paging response, no location information in HLR). CCBS recall: an indication informing subscriber A that destination B is idle. CCBS call: a call set-up from sub
40、scriber A to destination B resulting from subscriber As acceptance of a CCBS recall. CCBS request: A request by subscriber A against an NDUB destination B requesting that subscriber A be automatically informed when destination B becomes idle. The CCBS request shall be held in a CCBS queue pending th
41、e correct conditions for the CCBS request to be completed. Destination B: the entity addressed in the original call set up. Subscriber A: the subscriber that originated the call, activated a CCBS request and is uniquely identifiable for CCBS recall. Suspended CCBS request: a CCBS request which canno
42、t be served even if destination B is idle, because subscriber A is CCBS busy, not reachable or is not idle and ignores the CCBS recall. Resumed CCBS request: a CCBS request which was suspended before and has become not suspended as a result of subscriber A becoming idle, not CCBS busy or reachable a
43、gain. Automatic deactivation: an action by the network resulting in removal of all reference to a CCBS request without informing the subscriber. Automatic deactivation is performed after a successful CCBS procedure or for exceptional situations. Timers at the originating side (A): CCBS retention tim
44、er (T1): this timer specifies the amount of time that the network retains the call information when the call encounters busy. The value shall be greater than 15 seconds. The upper limit of the CCBS retention timer is a network option. CCBS service duration timer (T3): the maximum time the CCBS reque
45、st will be active within the network. The value of this period is a network option, in the range of 15 to 45 minutes. CCBS recall timer (T4): the maximum time the network will wait for a subscriber A response to a CCBS recall when subscriber A is idle. The value of this timer is a network option and
46、 shall be in the range 20 to 30 seconds. CCBS notification timer (T10): the maximum time the network will wait for a subscriber A response to a CCBS recall when subscriber A is not idle and not CCBS busy. The value of the timer is a network option and shall be in the range 20 to 30 seconds. CCBS res
47、ume timer (T11): the timer started as soon as a suspended CCBS request is resumed, making sure only one CCBS request is becoming resumed at a time. Duration of the timer shall allow a CCBS recall resulting from the destination side CCBS queue being processed. The value of the timer is a network opti
48、on and shall be in the range 20 to 25 seconds. Timers at the terminating side (B): CCBS service duration timer (T7): is the timer which specifies the maximum length of time the CCBS request will be held within the network. The value of this period is a network option shall be greater than 45 minutes
49、. Destination B idle guard timer (T8): the time the network will wait after destination B has become idle before initiating a “CCBS recall“ to subscriber A. The value of this timer is a network option and shall be in the range 0 to 15 seconds. NOTE 1: This timer enables destination B to initiate a call before any notification is given to subscriber A that destination B has become idle and prevents destination B to receive incoming calls. CCBS recall B timer (T9): is the timer, which supervises the CCBS recall establishment on the B-side. The value is a
