If true, how many time UE no service? So, LTE coverage hole s can be found anywhere with poor radio quality. Handover without TAU – Part 1. Please leave your comment if you have a question or suggestion. Initial Attach in Another City 4.

Initial Attach in Another City. It’s very helpful for me. Cell Reselection without TAU. So, actual procedures in real cases of moving to another city may vary depending on how each operator configures the network, 33gpp implements the network nodes. Move to Another City 3. English Korean About Us. This cause value is used here just as an example.

Next documents will discuss other interesting topics. Move to Another City. Handover without TAU – Part 3.

So, in real networks, UE performs a handover to a neighbor cell or cell reselection, instead of being detached from the network as seen in this document. The Korean LTE networks are 3gp;, and thus services are available anywhere in the country, unlike the cases presented in this document. Thank you for visiting Netmanias!

Initial Attach in Another City 4. Hi, I like this helpful article, but I have one quetion related to the implicit detach timer.

Please leave your comment if you have a question or suggestion. 3ypp know when the UE moves out of the shadow area while the implicit detach timer is running, the UE should establish a radio link to the 3gp by operations such as a tracking area update or a service request.

Stage 3 for Session management, bearer control and QoS aspects. To avoid that large amounts of UEs initiate deferred requests almost simultaneously, the MME should select the Mobility Management back-off timer value so that the deferred requests are not synchronized. General Versions Responsibility Related.

MPS is based on the ability to invoke, modify, maintain and release sessions with priority, and deliver the priority media packets under network congestion conditions. This functionality applies to all mobility procedures.

During Tracking Area Update procedures, including a TAU as part of a handover, the target 2341 ignores any mobility or access restrictions for UE with emergency bearer 2401 where required by local regulation.

CT6 aspects of SAE. This is to minimize unneeded signalling after the Mobility Management back-off timer expires. If it has not been released: A term defined in the present document takes precedence over the definition of the same term, if any, in TR The present document has not been subject to any approval process by the 3GPP Organizational Partners and shall not be implemented.

Issues for CT1 TR Earthquake and Tsunami Warning System. Also UEs that had attached for normal services and do not have emergency bearers established and are camped on a cell in limited service state e. The above functionality is to diminish the performance advantage for UEs that do not support the NAS level back-off timer e.

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

The configuration of a UE for low access priority and Access Class are configured independently of each other. This allows for rejection of subsequent requests without HSS signalling when the congestion situation resulting from UEs with a particular subscribed APN persists. Receiving emergency services in limited service state does not require a subscription. It is assumed that the mechanisms described in this entire clause are 2340 by Stage 3 3gp a manner that allows extensibility and forward compatibility.

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. Version created with approved RRC connection re -config.

Updated with CRs approved at If a Service User belongs to one of the special access-classes as defined in TS 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.

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.

Serving GW Service Area: 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.

If either of the above procedures for GW relocation are initiated while the UE has active applications, it may cause disruption of services that are affected if the IP address changes. 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.

This indication is per TAI list. History Action date Action Author. No records to display. MPS supports priority sessions on an “end-to-end” priority basis. 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.

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. Attach for RN preconfiguration.

If authentication fails, the 2341 is granted access and the unauthenticated IMSI retained in the network for recording purposes.

SA 2 Secondary responsible groups: Refer to TS 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.

For discrepancies between this overview clause and the detailed procedure and function descriptions the latter take precedence. Explicit reference points are not defined for these routes. In addition the MME may off-load a cross-section of its subscribers with minimal impacts on the network and users e.
