The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. The specific functionality is described in the affected procedures and functions of this specification. The MME implementation may need to take into account the fact that eNodeBs compliant to Release 9 and earlier version of the specifications do not support the percentage overload indication.

Goltigrel The low access priority indicator in NAS signalling and the corresponding low access priority for RRC connection establishment are only used by the network to decide whether to accept the NAS request or the setup of the RRC connection respectively. System aspects of vocoder rate adaptation for LTE. The network supporting emergency services for UEs in limited service state provides emergency bearer services to these UE, regardless whether the UE can be authenticated, has roaming or mobility restrictions or a valid subscription, depending on local regulation.
MME Pool Areas may overlap each other. The use of the certificate-based and pre-shared key solutions is specified in Annex D of TS A UE which only has bearer s related to emergency bearer service. However, the home operator can take care to prevent a subscription for Access Class from being used in a UE configured for low access priority. UEs can be configured for one or more of the above options. Explicit reference points are not defined for these routes.
Serving GW Service Area: Also UEs that had attached for normal services and do not have emergency bearers established and are camped on a cell in limited service state e.
These permit node specific features to be developed to protect the networks. To avoid that large amounts of UEs initiate deferred requests almost simultaneously, the MME should select the Mobility Management back-off timer value so that deferred requests are not synchronized.
This reference point corresponds to Gi for 3GPP accesses. References are either specific identified by date of publication, edition number, version number, etc. During 3ypp overload situation the MME should attempt to maintain support for emergency bearer services. SA2 system aspects of vocoder rate adaptation for LTE.
Attach for RN preconfiguration. For emergency bearer services any EPC functions, procedures and capabilities are provided according to clause 4 except when specified differently in the following sections.
In addition to this shared radio access network the operators may or may 3gpp have additional dedicated radio access networks, like for 3gpp, 3G or 2G radio access networks. Under change control Type: The low access priority indication may be included in charging records by the visited and home networks.
The other roaming architectures with services provided by the home network do not apply for emergency services. UEs that camp normally on a cell, i. Specification withdrawal has failed. Stage 2 for Relays for LTE. However, these UEs have the capability to generate normal quantities of signalling. If it has not been released: Direct Transfer … 5b. This allows for rejection of subsequent requests without HSS signalling when the congestion situation resulting from UEs with a particular subscribed APN persists.
When the UE receives a handover command, the UE shall proceed with the handover procedure regardless of whether Mobility Management back-off timer is running. Deleted — Architecture enhancements for non-3GPP accesses. Related Posts.
Vijora 3pgp 3 SAE impact on existing capabilities. Packet Routing and Transfer 3gppp. The Organizational Partners accept no liability for any use of this Specification. When the UE receives a handover command, the UE shall proceed with the handover procedure regardless of whether Mobility Management back-off timer is running. This functionality is used by the Attach procedure and by the UE Requested PDN Connectivity procedure, in both cases when establishing emergency bearer services. Additionally, the local network may want to provide IMS emergency call support differently than what is allowed by a UE subscription. Emergency bearer services are functionalities provided by the serving network when the network is configured to support emergency services.
