However, the UE is allowed to initiate the Mobility Management procedures for high priority access and emergency services even when the Mobility Management back-off timer is running. Following the failure of 3gp more preferred PLMN, UEs configured as above might change to other local competing networks. After this operation is complete, the RN detaches from the network using the normal UE initiated detach procedure, see clause 5.

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. The UE may be registered in multiple Tracking Areas. If the Service User is not authorized to use on-demand priority request, the Service User receives priority treatment 2340.

Network Access Control Functions. In addition, under unusual circumstances, the MME shall restrict the load that its eNodeBs are 234401 on 33gpp if it is configured to enable the overload restriction. 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.

Packet Routing and Transfer Functions. 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 3gp; is not stored by the UE as a forbidden area, the UE may 2401 detach and reattach to normal services without waiting for the emergency PDN connection deactivation by the PDN GW.


Non-roaming architecture for 3GPP accesses. Though motivated by scenarios and use cases defined in TS Such UEs behave as emergency attached.

Click to see all versions of this specification. 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. BBF convergence and network based mobility. 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.

Rx session, Gx session, S9 session etc. The following CSG related functions are defined: The load re-balancing can off-load part of or 223401 the subscribers. – /ftp/specs/archive/23_series/23.401/

A change in UE. The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval.

Specific situations that require setting the RRC establishment cause to emergency are described in TS 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.

Architecture aspects of EHNB. Roaming architecture for local breakout, with visited operator’s application functions only 4.

Failure of the normal initial attach may occur e. All UEs are allowed. The configuration of a UE for low access priority and Access Class are configured independently of each other. Usage of S12 is an operator configuration option. 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.

Under change control Type: The authentication function is performed in association with the Mobility Management functions. Serving GW Service Area: The MME does not treat certificate-based and preshared key-based solution differently. Stage 3 for security aspects of LTE Access. With minimal impact on network and the user’s experience, the subscribers should be off-loaded as soon as possible. Alternative MME implementations are permitted, however, the externally visible MME behaviour should conform to the above description.


Evolution of Policy Control and Charging. Updated with approved CRs at Remarks 1 Creation date Author Remark. 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.

To avoid that large amounts of UEs initiate deferred requests almost simultaneously, the MME should select the Session Management back-off timer value so that deferred requests are not synchronized. It is up to RN implementation how it ensures no UE is connected.

Delete Subscriber Data functional procedure – can’t find in 3GPP : LTE

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. It applies to both the non-roaming case and the roaming case and some functionality may be dependent upon the existence of appropriate roaming agreements between the operators.

Created from version The other roaming architectures with services provided by the home network do not apply for emergency services. Each route consists of the originating node, zero or more relay nodes and the destination node. MTC functionality is performed by UEs that are configured to support different options as described in clause 4.

References are either specific identified by date of publication, edition number, version number, etc. These include some time randomisation to guard against a repeat of a load peak. No records to display.
