Abstract: A mobile wireless device maintains registration on two parallel wireless communication networks that each use different wireless communication protocols. In response to a first connection request received from a first wireless network, the mobile wireless device tunes a single receiver contained therein from the first wireless network to a second wireless network. Subsequently in response to a second connection request received from the second wireless network, the mobile wireless device connects to the second wireless network.

Abstract: A method includes a wireless mobile device communicating with a wireless network via an evolved high rate packet data (eHRPD) interface. The wireless mobile device may receive a vendor specific network control protocol (VSNCP) packet such as a terminate-request packet, for example, that indicates the wireless network has requested a PDN disconnection. The VSNCP packet includes a cause code that indicates a reason for the PDN disconnection request. The wireless device may use the cause code to determine the reason for the PDN disconnection request. Accordingly, in response to receiving the VSNCP packet, the wireless mobile device may perform one or more operations in an effort to resolve any issues that may have caused the PDN disconnection request.

Abstract: A user identity module (UIM) is incorporated in user equipment such as a mobile phone or mobile device. The UIM is configured to provision itself while roaming away from a home network as follows. The UIM may: send to the UE a request for information identifying a current radio access technology (RAT) that the UE is camped on; receive the current RAT information from the UE; send to the UE a request for network location information, where the network location information identifies a network in which the UE is currently camped; receive the network location information from the UE; generate an access point name (APN) using the current RAT information and the network location information; and open a channel through the network to a remote agent (e.g., a provisioning server) using the access point name.

Abstract: A processor in a mobile wireless device provisions a user identity module (UIM) card in the mobile wireless device in response to a user command. The processor detects a user command to provision the UIM card and reads a provisioning status of the UIM card from a UIM card provisioning status file in the UIM card. When the provisioning status is “not provisioned”, the processor establishes a bearer independent protocol (BIP) data connection to a server in a wireless network and exchanges provisioning data between the server and the UIM card until the UIM card commands the processor to close the BIP data connection. In representative embodiments, the UIM card provisioning status file includes fields for a UIM card provisioning status, a UIM card software version and a UIM card provisioning date/time, and the processor updates the fields during provisioning.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method and apparatus for packet classification and prioritization using a user datagram protocol (UDP) header in a mobile wireless device. The mobile wireless device includes an application processor and a transceiver. The application processor sets a value of a field embedded in a higher layer packet and transfers the higher layer packet to the transceiver. The transceiver receives the higher layer packet from the application processor and reads the set value of the embedded field. The transceiver clears the value in the embedded field and creates at least one lower layer protocol data unit from the higher layer packet. The transceiver maps the lower layer protocol data unit to a wireless access channel having a transmission property based on the read value of the embedded field. In representative embodiments, the embedded field is an optional checksum in a UDP header.

Abstract: A current location of a mobile system in a wireless network can be determined by using information provided by a base station in communication with the mobile system. The information can include a system identifier (SID) table and a local time offset (LTM_OFF) value and a daylight savings time (DAYLT) value. The SID table is used to provide a mobile country code (MCC) associated with a country in which the mobile device is located. The LTM_OFF value is used to provide a range of longitude values in which the mobile device is located. The current location of the mobile device is based upon at least the range of longitude values and the current country. The current location is used to build an optimized scan list that is used, in turn, to identify and acquire access to the preferred system by a mobile device.

Abstract: A jitter buffer in a Voice over LTE receiver may be influenced by radio level feedback (RLF) from both local and remote endpoints to preemptively adjust the jitter buffer delay in anticipation of predicted future losses that have a high probability of occurring. The radio events of the RLF and the scenarios that trigger the preemptive adjustments may be identified, and their use may be expressed in terms of mathematical formulas. In prior art designs, the instantaneous jitter is derived from a weighted history of the media stream, and consequently only packets that have already arrived are used to compute the instantaneous jitter to adjust the length of the buffer. By providing and using RLF from both local and remote endpoints, the anticipated delay—for packets that have not yet arrived—may be used to preemptively adjust the buffer, thereby minimizing packet loss without introducing unnecessary delay.

Abstract: A wireless electronic device having first and second baseband processors is provided. In one suitable arrangement, radio-frequency power splitters and adjustable low noise amplifiers may be form in the receive paths. The use of power splitters allow signals associated with the first and second baseband processors to be received in parallel. In another suitable arrangement, radio-frequency switches are used in place of the power splitters. The states of the switches may be controlled using at least one of the first and second baseband processors. The use of switches instead of power splitters requires that wake periods associated with the first baseband processor and wake periods associated with the second baseband processor are non-overlapping. To ensure minimal wake period collision, a wake period associated with the second baseband processor may be positioned at a midpoint between two successive wake periods associated with the first baseband processor.

The method can include a wireless communication device sending a transmission for a pending HARQ retransmission process and receiving an ACK for the transmission.

Abstract: A connection with a network that includes a base station (BS) may be established by a user device (UE) via a wireless connection, for conducting communications using semi persistent scheduling (SPS) in a connected discontinuous reception (C-DRX) mode. The SPS transmit periodicity may be adjusted with respect to the SPS activation command and the SPS interval UL (for uplink). Data may then be transmitted during the C-DRX On-Duration periods according to the determined SPS transmit periodicity. In some embodiments, the SPS transmit periodicity is adjusted such that following a first C-DRX On-Duration period when an SPS activation command is received, SPS data transmission occurs a specified number of subframes earlier during each subsequent C-DRX On-Duration period than in the first C-DRX On-Duration period. The SPS data transmission in each subsequent C-DRX On-Duration period may take place as soon as the UE device wakes up during the On-Duration period.
