20120294173 | APPARATUS AND METHODS FOR CLIENT SERVER INTERACTION IN HYBRID NETWORK ENVIRONMENTS - Methods and apparatus for modifying network management for hybrid operation. In one embodiment, the networks include an LTE network and a CDMA 1X network, and a mobile device can place CDMA 1X voice calls while registered with the LTE network. However, since the mobile device cannot simultaneously measure information for the LTE network while connected to the CDMA 1X networks, the mobile device modifies measurements and behaviors reported to the LTE network. In one implementation, the mobile device accounts for the time switched away from the LTE network in one or more subsequent reports thereto. | 11-22-2012 |
20120294291 | APPARATUS AND METHODS FOR NETWORK ASSISTED HYBRID NETWORK OPERATION - Methods and apparatus for minimizing scheduling collisions between networks. In one embodiment, the networks are substantially unsynchronized, and during hybrid network operation (e.g., LTE and CDMA 1× operation), a mobile device can place CDMA 1× voice calls while registered with the LTE network. However, since the LTE and CDMA 1× networks are not coordinated, the mobile device will experience scheduling collisions. In one variant, the LTE network accounts for predictable behaviors (such as CDMA 1× paging), and schedules low priority tasks during likely time interval conflicts. Consequently, even though the mobile device must tune away from the LTE network to check CDMA 1× pages, overall LTE network performance is minimally affected. | 11-22-2012 |
20120297070 | APPARATUS AND METHODS FOR OPTIMIZING SCHEDULED OPERATIONS IN HYBRID NETWORK ENVIRONMENTS - Methods and apparatus for intelligent scheduling of client device tasks based on one or more network scheduling constraints. During normal network operation, a client device performs an array of scheduled maintenance tasks to optimize network performance (e.g., signal strength measurements, etc.) However, during hybrid network operation, regularly scheduled maintenance tasks for a first network can interrupt higher priority tasks on other networks. Consequently, the present invention in one embodiment provides a method for a client device to properly prioritize and re-schedule maintenance tasks. For example, CDMA 1X cell selection (or cell re-selection) procedures have flexible time constraints, and can be postponed (or expedited) to minimize impact on LTE network traffic. | 11-22-2012 |
20120309391 | METHODS AND APPARATUS FOR ADAPTIVE NETWORK SELECTION - Methods and apparatus enabling dynamic and adaptive network selection. In one embodiment of the invention, a device quickly identifies the a subset of networks providing service to a particular location without obtaining and/or prioritizing a full list of all available networks. A “highest” priority network is selected for registration. For example, a mobile device that cannot locate its home (or last registered) network (e.g., Public Land Mobile Network (PLMN)), searches for any available network. The mobile device can identify its current location from information broadcast by any networks (e.g., a Mobile Country Code (MCC)). Once the mobile has identified its current location, it searches for prioritized networks within its current location. | 12-06-2012 |
20130286853 | APPARATUS AND METHODS FOR NETWORK DETECTION AND MITIGATION OF HYBRID CLIENT DEVICE OPERATION - Methods and apparatus for network-based detection and mitigation of hybrid client device reception outage events. For example, in one embodiment, a cellular device uses a single-radio solution to support circuit-switched calls on a CDMA 1X network and packet-switched calls on LTE. Periodically, the cellular device tunes away from LTE and monitors CDMA 1X activity, and vice versa. During these tuned-away periods, the network adjusts operation to mitigate adverse effects (e.g., underutilization of radio resources, synchronization loss, etc.). | 10-31-2013 |
20130294417 | APPARATUS AND METHODS FOR INTELLIGENT SCHEDULING IN HYBRID NETWORKS BASED ON CLIENT IDENTITY - Methods and apparatus for intelligent scheduling in hybrid networks based on client identity. For example, in one embodiment, the hybrid networks are cellular networks (e.g., LTE and CDMA 1X), and a cellular device uses a single-radio solution to support circuit-switched calls on a CDMA 1X network and packet-switched calls on LTE. Periodically, the cellular device tunes away from LTE and monitors CDMA 1X activity, and vice versa. The LTE network can infer the cellular device's tune away schedule, based on the device's identity, and the paging schedule algorithm of the CDMA 1X network. | 11-07-2013 |
20140220975 | Non-Intra-Frequency (NIF) Cell Reselection and Measurement in Wireless Communications - A wireless communication system is presented in which user equipment (UE) performs non-intra-frequency (NIF) cell reselection. The NIF cell reselection process can: detect, on a discontinues reception (DRX) cycle, whether a NIF for a second cell has passed a second reselection threshold; perform, on the DRX cycle, additional checks or measurements to determine whether a higher priority NIF for a third cell has passed a third reselection threshold; and continue a cell reselection process for the second cell and the third cell. The NIF cell reselection techniques can help ensure that the UE reselects to higher priority cells without expending an unnecessary amount power. | 08-07-2014 |
20150092644 | System and Method for Audio Frame Generation Alignment with LTE Transmission Opportunities - A station that generates data packets to be transmitted by the station such that the data packets spend a minimum amount of time in a buffer prior to transmission. The method includes receiving a specification for a connected discontinuous reception (C-DRX) cycle, the specification indicating when a plurality of onDurations of the C-DRX cycle occurs, the onDurations having a predetermined interval therebetween, receiving data at a known time relative to the C-DRX cycle, determining a modification to a conversion process that converts the data to data packets such that the data packets are stored in a buffer at a subframe immediately preceding one of the onDurations subsequent to the known time, performing the conversion process based upon the modification and storing the data packets at the subframe immediately preceding the one of the onDurations. In one embodiment, the data is raw audio data and the data packets are audio packets. | 04-02-2015 |
