In this release there is no other usage of storing the low access priority indicator in EPS Bearer contexts other than for the purpose to include it in charging records. SIPTO applies to both the non-roaming case and, provided appropriate roaming agreements are in place between the operators, to the roaming case.

Earthquake and Tsunami Warning System. Following the failure of a more preferred PLMN, UEs configured as above might change to other local competing networks.

Routing is the process of determining and using, in accordance with a set of rules, the route for transmission of a message within and between the PLMN s. Emergency bearer services are functionalities provided by the serving network when the network is configured to support emergency services.

Version created with approved This means the Serving GW selected for such subscribers may need to support both GTP and PMIP, so that it is possible to set up both local breakout and home routed sessions for these subscribers. Additionally, the local network may want to provide IMS emergency call support differently than what is allowed by a UE subscription.

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.

3ypp of the 3hpp initial attach may occur e. 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. Stage 3 for QoS mechanisms. A UE shall invoke one or more of the following mechanisms based on the configuration and capabilities of the UE: The Radio Access Network functionality is documented only to the extent necessary to describe the overall system. Stage 3 for Session management, bearer control and QoS aspects.


Created from version In addition, if Direct Tunnel is not established, it provides the user plane tunnelling. UEs can be configured for one or more of the above options. The load re-balancing can off-load part of or all the subscribers. This mechanism provides preferential access to UEs based on its assigned Access Class. The low access priority indicator in 3hpp signalling and 3gpp corresponding 2301 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.

This implies that an E-UTRAN UE needs to be able to discriminate between core network operators available in a shared radio access network and that these operators can be handled in the same way as operators in non-shared networks. The back-off timer is stopped as defined in TS The low access priority indication may be included in charging records by the visited and home networks.

For a specific reference, subsequent revisions do not apply. The concurrent use of AF’s in the home network and AF’s in the visited network is not excluded. These user plane forwarding routes can cross inter-PLMN boundaries e. MTC functionality is performed by UEs that are configured to support different options as described in clause 4. No records to display.

The emergency bearer contexts shall not be changed to non-emergency bearer contexts and vice versa. Gradual rather than sudden off-loading should be performed as 3gppp sudden re-balance of large number of subscribers could 33gpp other MMEs in the pool. 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.


Under change control Type: Emergency bearer services are provided to normal attached or emergency attached UEs and depending on local regulation, to UEs that are in limited service state. Spec Type Title Status Prime grp. Roaming architecture for local breakout, with visited operator’s application functions only 4.

3tpp networks that support network sharing as defined in TS The routing mechanism is required to find the correct old MME from the multiple MMEs that are associated with a pool area. CT6 aspects of SAE.

Expiry of this search timer will lead to the UE re-attempting to access the failed network, and then, if that network has not yet recovered, reaccessing one of the local competing networks. Click to see all versions of this specification. The present document has not been subject to any approval process by the 3GPP Organizational Partners and shall not be implemented. 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.

As normal signalling from large numbers of UEs may cause overload independently whether the UE is used for MTC or not, generic functionality for overload and congestion control is required. The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Stage 2 Security Architecture.
