AI Technical Summary

Problems solved by technology

A radio link failure (RLF) condition instructs the UE to perform RRC connection re-establishment, which involves at least three messages transmitted over the air interface, and in addition, there may be delays during handover (such as from RLF timer expiry delay) to declare radio link failure
Also, after RLF, the UE can control the selection of a new cell, which means that the network cannot control the cell selection

Embodiment Construction

[0023] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of claimed subject matter. It will be understood, however, to one skilled in the art that claimed subject matter may be practiced without these specific details. In other instances, well-known methods, procedures, components and / or circuits have not been described in detail.

[0024] In the following description and / or claims, the terms coupled and / or connected, as well as variants thereof, may be used. In particular embodiments, connected may be used to indicate that two or more elements are in direct physical and / or electrical contact with each other. Coupled may mean that two or more elements are in direct physical and / or electrical contact. However, coupled may also mean that two or more elements may not be in direct contact with each other, but yet still co-operate and / or interact with each other. For example, "coupled" may mean two or more...

Abstract

Briefly, according to one or more embodiments, a user equipment (UE) may enter into an E-UTRAN routing area paging channel state and be configured with an E-UTRAN routing area and an anchor eNodeB for identifying the UE (eNB) anchor identifier. The UE selects to a new cell without performing a handover procedure, and performs a cell update procedure. The UE may also enter into a cell update connected state and be configured with an anchor identifier. The UE selects to a new cell, performs a cell update procedure, performs a buffer request procedure, and performs a cell update procedure to download buffered data and perform data transmission with the new cell.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 145,370, filed April 9, 2015 (Docket No. P83804Z). Said Application No. 62 / 145,370 is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to controlled mobility of user equipment. Background technique [0004] The Internet of Things (IoT) refers to a collection of sensors with network connectivity to allow distributed collection and exchange of data. Large-scale deployment of large numbers of IoT devices to connect to existing wireless wide area networks (WWANs) operating under the 3rd Generation Partnership Project (3GPP) may present new problems that should be addressed. Evolved Packet Core (EPC) signaling may experience overload due to frequent state changes between the two current network states, namely the connected state (EMM_connected) and the idle state (EMM_idle). Also, many IoT d...
