摘要:
Certain aspects of the present disclosure propose methods and apparatuses for reducing power consumption associated with performing reselection between radio access technologies (RATs). For example, a network that supports first and second RATs may obtain a list of neighbor base stations of a third RAT and determine whether to transmit the neighbor list on the first RAT, the second RAT, or both. In another aspect, a user equipment (UE) may combine information from the neighbor lists received from the first and the second RATs, and decide whether to take measurements in the third RAT based on the combined information. The UE may also maintain a central entity with measurements taken in the third RAT based on the neighbor lists received from the first and the second RATs and decide whether to perform cell reselection based on measurements in the central entity.

Systems and methodologies are described herein that facilitate efficient transfer of quality of service (QoS) context during inter-radio access technology (RAT) handovers. In particular, techniques are described herein for establishing rules for whether a user equipment unit (UE) or an associated network should establish QoS for a mixed-mode application, identifying flow to bearer mappings when translating QoS across an inter-RAT handover, mapping QoS parameters of respective RATs, mitigating QoS depreciation upon multiple handovers, performing one or more actions if QoS is not acceptable in a new RAT, maintaining QoS during tunnel mode, and handling scenarios in which a UE moves between a RAT using network-initiated QoS and a RAT using UE-initiated QoS.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus monitors a page during a current paging cycle on a first frequency. In addition, the apparatus switches to a second frequency after the current paging cycle to receive multicast/broadcast information on the second frequency. Furthermore, the apparatus attempts to receive the multicast/broadcast information on the second frequency before a predetermined time.

A mobile device or access terminal of a wireless wide area network (WWAN) communication system is provisioned for Multi-Mode System Selection (MMSS) wherein an MMSS System Priority List (MSPL) is used with respect to the underlying system selection priority list (e.g., Private Land Mobile Network (PLMN) list). Relating a current location to one or more entries in an MMSS Location Associated Priority List (MLPLs) enables scaling a range of entries in the PLMN list, indicating whether the MSPL apply to the entire list of PLMNs stored in an access terminal or to some subset of the PLMN List. Similarly, the present innovation addresses whether the MSPL applies to the entire Preferred Roaming List (PRL) or some subset of a geo-spatial location (GEO) area.

An access terminal pre-registers with a second access network via a first access network to ensure a quick handover in the future. Frequent pre-registration attempts are avoided by implementing a hysteresis timer that restricts when a pre-registration process can be initiated. The hysteresis timer is started when pre-registration is initiated by the access terminal. No new pre-registration attempts are permitted if the hysteresis timer has not expired. An abort condition can cause the hysteresis timer to be aborted early, and a new pre-registration can be initiated. Access points in the first access network may be grouped into one or more pre-registration zones. If the access terminal moves from a first access point to a second access point, a new pre-registration is skipped if the first and second access points have the same pre-registration zone or the second access point is aware of the pre-registration zone for the first access point.

Aspects are described for redirecting wireless terminals between wireless networks. In a first embodiment, a coverage quality of user equipment within a first wireless network is monitored. Multiple candidate frequencies are then ascertained in response to the coverage quality to facilitate a communication between the user equipment and a second wireless network. The candidate frequencies are then communicated to the user equipment. In another embodiment, an indication of a plurality of candidate frequencies is received, and a failure in performing a handover from a first wireless network to a second wireless network is detected. For this embodiment, the handover is attempted via a primary frequency. An alternative frequency is then selected from the plurality of candidate frequencies in response to the failure, and a communication with the second wireless network is established via the alternative frequency.

Devices and methods are provided for system selection from a plurality of wireless system access technologies, such as a first group (e.g., 3GPP2 technologies) and a second group (e.g., 3GPP technologies). In one embodiment, the method may involve storing identification information pertaining to the first group in a database, wherein the database may concern the priority of ones of the access technologies pertaining to the second group. The method may also involve selecting a preferred access technology from one of the first and second groups based at least in part on the identification information stored in the database.
摘要:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus initiates a process for reselection from a first network (e.g., C2K) to a second network (e.g., LTE) by performing a measurement on a frequency indicated in a neighbor list received from a first cell in the first network. The neighbor list includes information indicating at least one frequency associated with the second network. The apparatus creates a state (e.g., starts an EUTRAReselect timer) associated with the frequency based on the measurement. The apparatus moves (e.g., performs an idle HO) from the first cell to a second cell in the first network. The apparatus determines whether to maintain the state upon the move from the first cell to the second cell.
