21、V13.0.0 (2016-01)53GPP TS 24.091 version 13.0.0 Release 131 Scope The present document gives the stage 3 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 ope
22、ration, registration, erasure, activation, deactivation, invocation and interrogation of call transfer supplementary 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 in
23、terface. In 3GPP TS 24.010 the general aspects of the specification of supplementary services at the layer 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,
24、3GPP TS 22.08x and 3GPP TS 22.09x-series. 3GPP TS 22.091 is related specifically to call transfer supplementary 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 trans
25、fer supplementary services. The procedures for Call Control, Mobility Management and Radio Resource management 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
26、 the present document: - Explicit Call Transfer (ECT) (see clause 4). 2 References The following 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, versi
27、on number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.

36、sfer (ECT) function should be invoked in association with two existing calls which one is answered 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)
37、. This ECT request indicates to the network that the mobile subscriber wishes the two calls to be connected 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 call
38、s, indicates the success of the ECT request to the served subscriber and disconnect afterwards the 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
39、condition it was in prior to the ECT request. The network confirms with the same transaction identifier. 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. ETSI ETSI TS 124 091 V13.0.0 (2016-01)73GPP TS
40、 24.091 version 13.0.0 Release 13During 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 from the network. If this timer expires the MS shall assume that the operation has failed, locally release the invokeID,
41、and may re-attempt the operation or inform the user of the failure. 4.2 Explicit Call Transfer invocation MS Network FACILITY (TI A-B/A-C) - Facility (Invoke = ExplicitCT) DISCONNECT/RELEASE/RELEASE COMPLETE (TI A-B/A-C) Facility (Invoke = ProcessUnstructuredSS-Request (ussd-DataCodingScheme, ussd-S
