This TS specifies the procedures used at the radio interface for normal operation, registration, erasure, activation, deactivation, invocatio
20、n and interrogation of call transfer supplementary services within the 3GPP system. The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of this TS, it will be re-released by the TSG with a
21、n identifying change of release date and an increase in version number as follows: Version 3.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 Indicates TSG approved document under change control. y the second digit is incremented for all changes of
22、 substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the specification; ETSI ETSI TS 124 091 V15.0.0 (2018-07)53GPP TS 24.091 version 15.0.0 Release 151 Scope The present document gives the stage 3
23、description of the call transfer supplementary services. The present document specifies the procedures used at the radio interface (Reference point Um as defined in 3GPP TS 24.002) for normal operation, registration, erasure, activation, deactivation, invocation and interrogation of call transfer su
24、pplementary services. Provision and withdrawal of supplementary services is an administrative matter between the mobile subscriber and the service provider and cause no signalling on the radio interface. In 3GPP TS 24.010 the general aspects of the specification of supplementary services at the laye
25、r 3 radio interface are given. 3GPP TS 24.080 specifies the formats and coding for the supplementary services. Definitions and descriptions of supplementary services are given in 3GPP TS 22.004, 3GPP TS 22.08x and 3GPP TS 22.09x-series. 3GPP TS 22.091 is related specifically to call transfer supplem
26、entary services. The technical realization of supplementary services is described in 3GPP TS 23.011, 3GPP TS 23.08x and 3GPP TS 23.09x-series. 3GPP TS 23.091 is related specifically to call transfer supplementary services. The procedures for Call Control, Mobility Management and Radio Resource manag
27、ement at the layer 3 radio interface are defined in 3GPP TS 24.007 and 3GPP TS 24.008. The following supplementary services belong to the call transfer supplementary services and are described in the present document: - Explicit Call Transfer (ECT) (see clause 4). 2 References The following document
28、s 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. - For
29、a non-specific reference, the latest version applies.

38、and in the held state and the other is answered and active or alerting. The Mobile Station (MS) invokes the service by sending a FACILITY message to the network containing the ECT request (ECT request). This ECT request indicates to the network that the mobile subscriber wishes the two calls to be c
39、onnected together. The MS shall not change the basic call state or the auxiliary state of either call when sending ECT request. The network will normally accept the ECT request and connect the two calls, indicates the success of the ECT request to the served subscriber and disconnect afterwards the
40、served mobile subscriber from both calls (see figure 1). If the ECT request is not accepted, the network will indicate the error to the served subscriber (see figure 1) and leaves the two calls to the condition it was in prior to the ECT request. The network confirms with the same transaction identi
41、fier. The detailed coding of the different error values are specified in 3GPP TS 24.080. Which error value is used in which error case is described below. During the ECT operation the MS shall run a timer TECT. This timer is started when the operation is sent, and stopped when a response is received
42、 from the network. If this timer expires the MS shall assume that the operation has failed, locally release the invokeID, and may re-attempt the operation or inform the user of the failure.
