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.

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.
The low priority indication gets associated with 3gp PDN connection when it is established and it shall not change until the PDN connection is deactivated. Some of the MTC functions are controlled by subscriber data. While the Mobility Management back-off timer is running, the UE is allowed to perform Tracking Area Update if it is already in connected mode. Non-roaming architecture for 3GPP accesses. No records to Stage 3 for Session management, bearer control QoS aspects.
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. Any non emergency bearer services are deactivated, according to clause 5. The Handover Restriction List specifies roaming, area and access restrictions. Gradual rather than sudden off-loading should be performed 3gpo a sudden re-balance of large number of subscribers could overload other MMEs in the pool.
System Improvements to Machine-Type Communications. Stage 2 for Relays for LTE. Routing is the process of determining and using, in accordance with a set of rules, route for transmission of a message within and between the PLMN s. To counter these potential problems, the following standardised indications and mechanisms are provided in a generic manner. The other roaming architectures with services provided by the home network do not apply for emergency services.
These user plane forwarding routes can cross inter-PLMN boundaries e. A UE that can not be authenticated will be rejected. Impact to core network elements from the introduction of RNs and DeNB is minimized by reusing the existing nodes and protocols when interacting with the core network. During Tracking Area Update procedures, including a TAU as part of handover, the target MME ignores any mobility or access restrictions for UE with emergency bearer services 3bpp required by local regulation.
When data forwarding is used as part of mobility procedures different user plane routes may be used on the network configuration e. In this case the eNodeB shall, if supported, reduce the type of traffic indicated according the requested percentage see TS In the case of a reference to a 3GPP document including a GSM documenta non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
The network supporting emergency services for UEs in limited service state provides emergency bearer services to these UE, regardless whether the UE 3g;p be authenticated, has roaming or mobility restrictions or a valid subscription, depending on local In addition the MME may off-load a cross-section of its subscribers with minimal impacts on the network and users e.
The relaying architecture is shown in figure 4. It is assumed that the mechanisms described in this entire clause are designed by Stage 3 in a manner that allows extensibility and forward compatibility. Updated with CRs approved at These UEs are authenticated and may be in limited service state due to being in a location that they are restricted from service. The protocol option i. Four different behaviours of emergency bearer support have been identified as SA 2 Secondary responsible groups: Deleted — Architecture enhancements for non-3GPP accesses.
The emergency bearer contexts shall not be changed to non-emergency bearer contexts and vice versa. TOP Related Posts.

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. Deleted — Architecture enhancements for non-3GPP accesses. The configuration of a UE for low access priority and Access Class are configured independently of each other.
