Abstract: A user equipment is initially camped on an LTE/E-UTRAN cell (205). An eNodeB informs (210) the UE to return after circuit-switched fall-back, CSFB, and optionally provides re-direction/re-selection information. The UE then performs a CSFB (215) with a NodeB of a legacy network cell, such as GERAN/UTRAN/CDMA2000 cell. Upon release of the CSFB connection (220), the UE uses (230) the received re-direction information to identify a best cell candidate in LTE, and select back (235) to the LTE/E-UTRAN carrier.
Abstract translation: 用户设备最初驻留在LTE / E-UTRAN小区（205）上。 eNodeB通知（210）UE在电路交换回退（CSFB）之后返回，并且可选地提供重新定向/重新选择信息。 然后，UE与诸如GERAN / UTRAN / CDMA2000小区的传统网络小区的NodeB执行CSFB（215）。 在释放CSFB连接（220）时，UE使用（230）所接收的重新定向信息来识别LTE中的最佳小区候选，并且向LTE / E-UTRAN载波返回（235）。

Abstract: A cellular terminal detects any capability reporting trigger and responsively to such determination produces a cellular network authentication capabilities message indicative of cellular network authentication capabilities available for the terminal; and transmits the cellular network authentication capabilities message to the cellular network. The cellular network receives the network authentication capabilities message from a cellular terminal, selects a cellular authentication algorithm based on capabilities indicated by the network authentication capabilities message; and performs cellular authentication with the cellular terminal using the selected cellular authentication algorithm.

Abstract: A method, apparatus and computer program product are described for reducing delay when making a network connection between user equipment (UE) and a network node when a tracking area update (TAU) request has been denied during LTE reselection. Following a revised signaling protocol, a UE can avoid activation of a NAS Attach Retry timer and move directly to establishing a connection to the network, reducing the UE communications delay from about eleven seconds to less than one second.

Abstract: Methods and apparatus, including computer program products, are provided for delaying a service request. In one aspect there is provided a method. The method may include receiving, at a user equipment, a message including a service rejection sent by a network; starting a timeout period in response to the received message including the service rejection; and waiting to send an attach request to the network until at least one of a radio resource control connection release is received from the network or the timeout period expires. Related apparatus, systems, methods, and articles are also described.

Abstract: Methods and apparatus, including computer program products, are provided for emergency call handling. In one aspect there is provided a method. The method may include receiving, at a user equipment, an indication from a network, the indication representative of at least one of whether a carrier grade voice over cellular packet data call is available at a cell serving the user equipment or whether an over-the-top service is available at the cell serving the user equipment; and initiating, by the user equipment based on the received indication from the network, a call via the over-the-top service, when the indication represents the carrier grade voice over cellular packet data call is not available at the cell serving the user equipment and the over-the-top service is available at the cell serving the user equipment. Related apparatus, systems, methods, and articles are also described.

Abstract: A method, apparatus and computer program in which a cellular terminal: transmits a request that requires authentication procedure triggering to a cellular network and responsively receiving from the cellular network an authentication request message with an indication of a selected cryptographic algorithm from a group of a plurality of cryptographic algorithms; decodes the authentication request message to a decoded authentication request according to the selected cryptographic algorithm and based on a shared secret known by the cellular terminal and a network operator of the cellular terminal; based on the decoded authentication request, the shared secret and the selected cryptographic algorithm, produces and encrypts an authentication response message; and transmits the authentication response message to the cellular network.

Abstract: A cellular terminal transmits a request that requires authentication procedure triggering to a cellular network and responsively receives from the cellular network an authentication request message with an indication of a selected cryptographic algorithm from a group of a plurality of cryptographic algorithms. The cellular terminal attempts to decode the authentication request message to a decoded authentication request according to the selected cryptographic algorithm and based on a shared secret known by the cellular terminal and a network operator of the cellular terminal. The cellular terminal produces a determination whether the attempt was successful and the cellular terminal supports the selected cryptographic algorithm in authenticating to the cellular network; and in case the determination is positive, based on the decoded authentication request, the shared secret and the selected cryptographic algorithm, produces and encrypts an authentication response message and transmits the authentication response message to the cellular network; and in case the determination is not positive, produces and sends to the cellular network a failure report.
