摘要： An enhanced paging mechanism is provided for UEs waking up from a very long paging cycle to improve paging robustness and flexibility. Enhanced paging includes absolute time paging (ATP) and paging with extended wakeup time. For absolute time paging, a UE receives ATP configuration and uses the actual wall time to calculate paging occasion if a condition is satisfied. In one embodiment, the wall time is acquired from at least one of an internal UE clock, a GPS time, information broadcasted from the network, or information from a higher layer signaling. For paging with extended wakeup time, a UE applies a long paging cycle followed by multiple normal paging cycles after waking up from the long paging cycle. In one embodiment, the long paging cycle is infinite and the UE enters normal paging cycle only upon TAU-triggered paging or uplink traffic.

摘要： A method of extended DRX paging includes a base station that transmits extended DRX configuration information and a User Equipment (UE) receives the extended DRX configuration from the base station. The UE determines a first number of frames that are included in a hyper-frame based at least in part on the extended DRX configuration information and selects a hyper-frame number. The hyper-frame number is based at least in part on the extended DRX configuration information. The UE maintains a hyper-frame count and the hyper-frame count is incremented after each hyper-frame. The UE then goes into sleep mode and the UE determines a wake up time before a standard DRX cycle that occurs during the selected hyper-frame. The UE may also determine a first wake up time and a second wake up time based on the selected hyper-frame number and synchronization error between a first cell and a second cell.

摘要： A UE initiates an MMTEL service in RRC Idle mode in a mobile communication network. The UE acquires access control information from a base station. The access control information comprises SSAC configuration information, ACB parameters information, and ACB bypass information. The ACB bypass information indicates whether ACB is applicable to MMTEL service type. The UE then performs SSAC check for the MMTEL service based on the access control information. The UE also performs ACB check for the MMTEL service if ACB is applicable to the MMTEL service. Otherwise, the UE bypasses the ACB check for the MMTEL service. The selective ACB mechanism can prioritize or deprioritize services based on operator's requirement.

摘要： A method of uplink shaping and extending UE in RRC Idle Mode is proposed. The UE processes a data packet to be sent to the network. The data packet is associated with a traffic type. If the data packet belongs to a normal traffic type, then the UE enters RRC Connected mode and thereby transmitting the data packet to the network. If the data packet belongs to a background traffic type, then the UE buffers the data packet and the UE is prohibited from entering RRC Connected mode until a triggering condition is satisfied for uplink transmission. The proposed mechanism achieves power saving by reducing the activity of uplink transmission. In addition, the proposed mechanism also reduces signaling overhead to enhance network efficiency.

In other embodiments of the invention, the UE configures an idle mode trigger condition. The UE detects one or more predefined traffic condition. Based on the detected traffic conditions, the UE may restart the inactivity timer. In other embodiments of the invention, the UE detects one or more predefined traffic conditions. The UE adaptively adjusts RLF triggering parameters based on the detected traffic conditions.

摘要： An enhanced access control method is proposed for machine-type communications (MTC) in a 3GPP LTE-Advanced network. An MTC device is configured for enhanced access barring (EAB). When the MTC device attempts access to the network, the NAS layer checks whether EAB is applicable for the MTC device. If yes, then the NAS layer forwards EAB configuration to the AS layer for further EAB control. Based on the EAB configuration, a base station broadcasts EAB information to UEs via system information block. The EAB information indicates whether barring is applied to a number of EAB categories and a number of access classes. Based on the EAB information, the MTC devices performs EAB for access attempt to RRC. If access is not barred under EAB, then the MTC device further performs ACB for access attempt to RRC.

摘要： A method of providing Local IP Access (LIPA) indication is proposed. In one novel aspect, an enhanced cell selection method is proposed using LIPA capability information. Based on LIPA capability related information, a UE is able to prioritize LIPA-capable cells and establish a corresponding packet data network (PDN) connection accordingly. In one embodiment, LIPA information is informed to the UE via Non Access Stratum (NAS) signaling. The UE stores LIPA capability information when receiving a NAS message from a mobility management entity (MME). Later on, when the UE performs cell selection or reselection in idle mode, the UE can use the stored LIPA capability information to prioritize LIPA-capable cells.

摘要： A method of power headroom reporting (PHR) is proposed. A UE is configured with a plurality of component carriers (CCs) and is served by one or more power amplifiers (PAs) in a wireless system with carrier aggregation. The UE determines transmit power limitation (TPL) information that comprises a set of TPL values, each TPL value corresponds to a UE-configured maximum transmit power for UE-level, PA-level, and CC-level. The TPL information is then reduced to non-redundant TPL values. Based on the non-redundant TPL values, the UE determines power headroom (PH) information that comprises a set of PH values. Each PH value equals to a TPL value subtracted by a UE-calculated transmit power. The UE reports the PH information to a base station via a fixed-length or variable-length MAC CE at each PHR reporting instance.
