The copyright and the foregoing restriction extend to reproduction in all media. 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. Spec Type Title Status Prime grp. After any such Detach procedure, the back-off timer continues to run. The following CSG related functions are defined: In addition, to protect the network from overload the MME has the option of rejecting NAS request messages which include the low access priority indicator before rejecting NAS request messages without the low access priority indicator see clause 4.

The low access priority indication may be included in charging records by the visited and home networks. The details of the selection are implementation specific.

The total signalling from large numbers of UEs is a concern in at least two situations: 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. Stage 2 BB I: MPS is supported in a roaming environment when roaming agreements are in place and where regulatory requirements apply.


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. Are you sure you want delete specification?


Emergency bearer services are functionalities provided by the serving network when the network is configured to support emergency services. The present document has not been subject to any approval process by the 3GPP Organizational Partners and 3gp; not be 3tpp.

Depending on local regulation and an operator’s policy, the MME may allow or reject an emergency attach request for UEs in limited service state. However, extreme care is needed to ensure that this load re-balancing does not overload other MMEs within the pool area or neighbouring SGSNs as this might lead to a much wider system failure. The Handover Restriction List specifies roaming, area and access restrictions.

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. By making the centre of this set of tracking areas close to the UE’s current location, the chance of a UE rapidly making another tracking area update can be reduced. The selection is based on network topology, i. No records to display. All UEs are allowed.

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. This reference point corresponds to Gi for 3GPP accesses. The specific functionality is described in the affected procedures and features of this and other specifications.


These UEs are authenticated and may be in limited service state due to being in a location that they are restricted from service. If all of the PDN connections for the UE need to be relocated, the MME may initiate the “explicit detach 233401 reattach required” procedure as specified in clause 5.

This Specification is provided for future development work within 3GPP only. Service Users as per TS A UE that can not be authenticated will be rejected.

MME Pool Areas may overlap each other. Refer to TS Stage 2 for Local IP Access. 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. Stage 3 3hpp Session management, bearer control and QoS aspects. The Mobility Restriction functionality is provided by the UE, the radio access network and the core network.

Use of a too short timer for the more preferred PLMN search can both prevent the failed network from recovering, and, impose more load on the local competing networks.
