    摘要: In geographical areas with incomplete coverage of Time Division Synchronous Code Division Multiple Access (TD-SCDMA) networks, it may be beneficial for a multimode User Equipment (UE) to handover to a Global System for Mobile Communications (GSM) network. Before handover, a multimode UE may receive an indication from a serving TD-SCDMA cell to enter a Discontinuous Reception (DRX) mode and perform measurement on a nearby GSM cell. After measurement, the UE receives a grant from the serving TD-SCDMA cell allowing the UE to transmit a measurement report to the serving TD-SCDMA cell. The TD-SCDMA cell may use the measurement report to determine if the multimode UE should handover to the GSM cell.

    摘要: Aspects of the present disclosure allow a mobile station (MS) to maintain data activity while performing handover operations within the WiMAX network and listening to a CDMA 1x paging cycle. According to aspects, the MS maintains timing of a base station (BS) in a first radio access technology (RAT) and a BS in a second RAT. The MS may determine an expected timing of a paging cycle in the second RAT and send a sleep request to the BS in the first RAT such that the sleep interval coincides with the timing of the paging cycle in the second RAT. The MS may perform operations to ensure a sleep interval, after performing handover operations, coincides with the timing of the paging cycle in the second RAT.

    摘要: Wireless communication is implemented by a multi-mode user equipment (UE). The method includes selecting a continuous time period during a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) voice call. The voice call is via a Node B. The selected continuous time period includes multiple subframes. The method also includes preventing the UE from communicating with the Node B during the selected continuous time period, or at least preventing downlink communications with the Node B. The method further includes acquiring a Global System for Mobile communications (GSM) signal from at least one GSM cell during the selected continuous time period. The UE can handover to a selected GSM cell based on the measurements of the acquired GSM cell(s).

    摘要: Embodiments provide methods, systems, and/or devices to identify and/or determine a closest base station to a multi-mode mobile device among the multiple wireless communications technologies, such as different Radio Access Technologies (RATs). Having identified a closest base station to the multi-mode mobile device among the multiple wireless communications technologies, the mobile device's location may be estimated using location information regarding the closest identified base station. In some cases, a handover or other procedure may be performed with respect to the mobile device and the closest identified base station. The multiple wireless communications technologies may include, but are not limited to, WiMAX, CDMA 1x, LTE, and/or EVDO.

    摘要: Methods and apparatuses are provided that include selecting measurement types for measuring neighboring cells based in part on a change in device location. Where a change in location is relatively small, a device can perform less precise more efficient measurements of the neighboring cells to conserve power and/or processing time than where the change in location is larger. The neighboring cells can operate on a difference frequency than a serving cell; thus, measuring the neighboring cells using more precise measurements can utilize radio frequency (RF) calibration over the different frequency. Where a change in device location is below a threshold, however, less precise measurements that do not use RF calibration can be utilized to measure the neighboring cells.
