Should the TSG modify the contents of this TS, it will be re-released by the TSG with an identifying change of release dat
27、e and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technic
28、al enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the specification; ETSI ETSI TS 122 129 V14.0.0 (2017-03)63GPP TS 22.129 version 14.0.0 Release 141 Scope The scope of this document includes service requirements for ha
29、ndover maintaining continuity of service to a wireless terminal as it moves between the radio coverage area, or “cells“, associated with different base station sites. This functionality is called “handover“. Handover can also occur due to change of radio resource providing a service without necessar
30、ily any change of the base stations involved. In particular, when the radio resources providing a service change from one of the UTRA radio access modes to the other (UTRA-FDD and UTRA-TDD), this is regarded as handover. Particular emphasis has been placed on the description of requirements for serv
31、ice continuity within UTRAN and between UTRAN and GERAN. It is a key requirement to allow for dual or multi-mode terminals to handover traffic from UTRAN to GERAN and vice versa. This document describes the service requirements for intra- and inter- system handover. The following subject areas are w
32、ithin the scope of these service requirements: - User perceived performance that may be influenced by handover; - Operational requirements relating to handover; - Security requirements. The requirements set forth in this document are service requirements, in that they fulfil the following: - The req
33、uirements are independent of the implementation of the UTRAN; - The extent to which the requirements are met are in principle verifiable using observables that are not internal to the UTRAN. 1.1 Situations in which Service Requirements apply The service requirements in this document are as far as po
34、ssible independent of the implementation. They therefore apply to situations where handover would occur regardless of how the radio access network is implemented. Situations envisaged are: - Handover within UTRAN due to change of radio resource caused by UE movement between areas covered by differen
35、t transmitters; - Handover within UTRAN due to change of UTRA radio access mode; - Handover due to change of radio system. It is possible that handover (i.e. change of radio resource) will occur in other situations, for example the technical implementation of the UTRAN may necessitate it or O - The
36、service requirements for handover occurring in situations such as O the source and destination network addresses need to be specified in each message. Transferred information cannot be guaranteed of ordered delivery. Connectionless bearer services lifetime is reduced to the transport of one message.
37、 GERAN coverage: an area where mobile cellular services are provided by a GERAN in accordance with GERAN specifications. UTRAN coverage: an area where mobile cellular services are provided by a UTRAN in accordance with UTRAN specifications. Multi mode terminal: UE that can obtain service from at lea
38、st one UTRA radio access mode, and one or more different systems such as GERAN bands or possibly other radio systems such IMT-2000 family members. Handover: The process in which the radio access network changes the radio transmitters or radio access mode or radio system used to provide the bearer se
39、rvices, while maintaining a defined bearer service QoS. Intra PLMN handover: Handover within the same network, i.e. having the same MCC-MNC regardless of radio access system. Note: this includes the case of UTRAN GERAN handover where MCC-MNC are the same in both cases. Inter PLMN handover: Handover
40、between different PLMNs, i.e. having different MCC-MNC. Inter system handover: Handover between networks using different radio systems , e.g. UTRAN GERAN. UTRA Radio access mode: the selected UTRA radio access mode i.e. UTRA-FDD; UTRA-TDD. Radio system: the selected 2ndor 3rdgeneration radio access
41、technology. ETSI ETSI TS 122 129 V14.0.0 (2017-03)83GPP TS 22.129 version 14.0.0 Release 14Service Continuity: The means for maintaining active services during changes in the coverage areas or their characteristics without, as far as possible, the user noticing. Note that Service Continuity can be a
42、chieved by handover, cell re-selection or other mechanisms. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: UE User equipment 4 General Principles governing service continuity 4.0 General Principles for service continuity The general principles for serv
43、ice continuity described in this specification refer to service continuity within the UTRAN, within the GERAN and between the UTRAN and GERAN. As a principle, the requirements on service continuity characteristics should be according to the target network on which the service is maintained. Service
44、requirements for seamless mobility between multiple heterogeneous access systems beyond only UTRAN and GERAN are contained within TS 22.278 2. 4.1 Service Continuity Scenarios Service continuity shall support the following scenarios: 1. Continuity of active CS services when moving within UTRAN, with
45、in GERAN and between UTRAN and GERAN coverage areas. 2. Continuity of active GPRS sessions when moving within UTRAN, within GERAN and between UTRAN and GERAN coverage areas. 3. Continuity of active IM Services when moving within UTRAN, within GERAN and between UTRAN and GERAN coverage areas (that su
46、pport those IM services). Service continuity is not applicable for any call or session using resources specific to the source domain that cannot be maintained using resources in the target domain. 4.2 Service Continuity requirements For all scenarios, the specifications shall cover both service cont
47、inuity within the same PLMN (intra-PLMN) and between PLMNs (inter-PLMN), including the case where the PLMNs involved are operated by different network operators. It shall be possible for a user to roam between the different parts of a shared network without requiring any user intervention. The user
48、experience while roaming in a shared network shall be comparable to the user experience while roaming in a non-shared network. 4.2.1 Service continuity for CS The scenario numbers in this table refer to the scenarios in section 4.1.
