29、h 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 A side: is caused by the following condition: - while the CCBS recall timer T4 or the CCBS notificatio

30、n 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; while there is CCBS recall pending (Le. while the CCBS recall timer T9 is running). Subscriber A and Dest

31、ination B is indicated as idle if there are no active calls, no calls on hold and no call waiting for the subscribers. Subscriber A and Destination B is indicated as not reachable if one of the conditions defined in GSM 09.02 apply (e.g. IMSI detach, no paging response, no location information in HL

32、R). CCBS recall: an indication informing subscriber A that destination B is idle. CCBS call: a call set-up from subscriber 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 b

33、e automatically informed when destination B becomes idle. The CCBS request shall be held in a CCBS queue pending the 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, activa

34、ted a CCBS request and is uniquely identifiable for CCBS recall. Suspended CCBS request: a CCBS request which cannot 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 su

35、spended before and has become not suspended as a result of subscriber A becoming idle, not CCBS busy or reachable again. Automatic deactivation: an action by the network resulting in removal of ail reference to a CCBS request without informing the subscriber. Automatic deactivation is performed afte

36、r a successful CCBS procedure or for exceptional situations. Timers at the originating side (A): CCBS retention timer (Tl): 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

37、 of the CCBS retention timer is a network option. CCBS service duration timer (T3): the maximum time the CCBS request 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

38、a subscriber A response to a CCBS recall when subscriber A is idle. The value of this timer is a network option and shall be in the range 20 to 30 seconds. (GSM 02.93 version 7.0.0 Release 1998) 8 ETSI TS 1 O1 282 V7.0.0 (1 999-08) CCBS notification timer (T10): the maximum time the network will wai

39、t 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 resume timer (T11): the timer started as soon as a suspended CCBS request is resumed, making sure only one CCBS

40、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 option and shall be in the range 20 to 25 seconds. Timers at the terminating side (B): CCBS service duration time

41、r (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. Destination B idle guard timer (TS): the time the network will wait after destination B has become idle bef

42、ore initiating a “CCBS recall“ to subscriber A. The value of this timer is a network option and shall be in the range O 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 destinat

43、ion 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 network option and shall be shall be in the range of 40 to 55 seconds. NOTE 2: This timer prevents destination B from receiving other incoming calls t

44、han from subscriber A. NOTE 3: The timer values may vary from one PLMN to another and thus give the subscriber a slightly different perception of the service as she roams between PLMNs. 3.2 Abbreviations For the purposes of the present document the following abbreviations apply: CCBS NDUB Network De

45、termined User Busy Completion of Calls to Busy Subscriber Additional GSM related abbreviations may be found in GSM 01.04. 4 Description When subscriber A encounters a Network Determined User Busy (NDUB) destination B, subscriber A can request the CCBS supplementary service (i.e. activate a CCBS Requ

46、est against destination B). The network will then monitor the wanted destination B for becoming idle. When the wanted destination B becomes idle, then the network will wait a short time in order to allow destination B to make an outgoing call. If destination B does not make any outgoing call within

47、this time, then the network shall automatically recall subscriber A. When subscriber A accepts the CCBS recall, within a defined time, then the network will automatically generate a CCBS call to destination B. CCBS has to be supported by the originating, as well as by the terminating network. 4.1 Ap

48、plicability to telecommunications services The applicability of the CCBS supplementary service is defined in GSM 02.04.

49、 service shall be provided to subscriber A after prior arrangement with the service provider. 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 BSs. 5.1.2 Subscriber B Subscriber B is the user of destination B and is not provided with the CCBS supplementary service. However, if provided by the network operator/service provider as an option, subscriber B may elect not to be a target of CCBS requests. In this case, the size of her destination B CCBS queue sh
