Stage 3 SAE impact on existing capabilities. To allow the emergency attached UE to get access to normal services after the emergency call has ended and when it has moved to a new area that is not stored by the UE as a forbidden area, the UE may explicitly detach and reattach to normal services without waiting for the emergency PDN connection deactivation by the PDN GW. Serving GW Service Areas may overlap each other. If it has not been released: These UEs are authenticated and may be in limited service state due to being in a location that they are restricted from service.

A UE that can not be authenticated will be rejected. The other roaming architectures with services provided by the home network do not apply for emergency services.

The last received value of the throttling factor and throttling delay supersedes any previous values received from that MME. This functionality applies to all mobility procedures.

A routing mechanism and other related mechanism is defined for the MMEs. For emergency bearer services any EPC functions, procedures and capabilities are provided according to clause 4 except when specified differently in the following sections. Radio Resource Management Functions. 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.


The Radio Access Network functionality is documented only to the extent necessary to describe the overall system. While the Mobility Management back-off timer is running, the UE shall not initiate any NAS request for Mobility Management procedures except for Detach procedure and except for high priority access, emergency services and mobile terminated services.


Some of the MTC functions are controlled by subscriber data. 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. 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.

The UE is allowed to initiate the Session Management procedures for high priority accesss and emergency services even when the Session Management back-off timer is running. If this Implicit Detach timer expires before the UE contacts the 3ggpp, then the MME can deduce that the UE has been ‘out of coverage’ for a long period of time and implicitly detach the UE as described in clause 5. It is up to RN implementation how it ensures no UE is connected.

Only UEs that are authenticated are allowed. 3gppp 2 for Dedicated Core Networks. Click to see all versions of this specification. System enhancements for the use of IMS services in local breakout. Typically, this procedure should not be used when the MME becomes overloaded because the Load Balancing function should have ensured that the other MMEs in the pool area are similarly overloaded.

History Action date Action Author. Special care needs to be taken when offloading 3gpo Nodes. The use of the certificate-based and pre-shared key solutions is specified in Annex D of TS Any non emergency bearer services are deactivated, according to clause 5.

Usage of S12 is an operator configuration option. 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.

For discrepancies between 33gpp overview clause and the detailed procedure and function descriptions, the latter take precedence. Network Access Control Functions. 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.

MCC correction to change posi With minimal impact on network and the user’s experience, the subscribers should be off-loaded as soon as possible. Roaming architecture for local breakout, with home operator’s application functions only NOTE 2: In addition to this shared radio access network the operators may or may not have additional dedicated radio access networks, like for example, 3G or 2G radio access networks.

The RN follows normal UE behaviour, e. MPS is based on the 233401 to invoke, modify, maintain and release sessions with priority, and deliver the priority media packets under network congestion conditions. However, extreme care is needed to ensure that this load re-balancing does not overload 233401 MMEs within the pool area or neighbouring SGSNs as this might lead to a much wider system failure.

The specific functionality is described in the affected procedures and features of this and other specifications. The Mobility Restriction functionality is provided by the UE, the 3ggpp access network and the core network. Version created with approved Four different behaviours of emergency bearer support have 3glp identified as follows:
