摘要:
A DC tracking arrangement includes a first tracking unit for slow tracking receiving an input signal and generating a first output signal, a second tracking unit for fast tracking receiving the input signal and generating a second output signal, and a decision unit receiving the first and second output signal for selecting the first or second output signal.

Information can transfer from a transmitter to a receiver; however, the transmission can consume valuable resources. Therefore, a number of times a transmission is attempted can be tracked and compared against a threshold value. If the transmission occurs too many times—based upon the comparison—then a reset can occur. Tracking can occur for a protocol data unit and/or a control protocol data unit to determine if a reset should occur.

Network re-selection by an idle mobile device between multiple radio access technologies (RATs) is provided for communication networks without a network-based solution. When a user equipment (UE) enters idle mode while camped to a first RAT network, it initiates an out of service search procedure that causes the UE to search for other RATs within a same public land mobile network (PLMN). If another RAT network is detected, the UE determines whether the priority of the detected RAT is higher than the priority of the first RAT. When the detected RAT has a higher priority than the first RAT, the UE re-selects and camps to that detected RAT network. If the detected RAT does not have a higher priority or no other RAT is detected within the PLMN, the UE re-camps to the first RAT network.

Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

Devices and methods are provided for optimizing the timing of multi-mode system scans in a wireless communication environment. In one embodiment, the method may involve determining at least one of location and movement of a mobile entity (ME). The method may involve adjusting a timer between preferred system scans based on the at least one of the location and the movement of the ME. For example, determining may involve utilizing a movement sensor (e.g., an accelerometer and/or a voltage-controlled oscillator accumulator) to detect the movement of the ME, and/or receiving signals from a Global Positioning System or the like.
摘要:
A single receiver can collect multiple protocol data units at one time originating from different sources. While it can be desirable for higher priority protocol data units to be processed, loss of data unit portions can cause confusion to the receiver. Therefore, even if a higher priority protocol data unit transfers to the receiver while a lower priority data unit is being processed, the lower priority unit can be completed before processing the higher priority unit; thus, there can be a lower likelihood of confusion among protocol data units.

In accordance with aspects of the disclosure, a method, apparatus, and computer program product are provided for wireless communication. The method, apparatus, and computer program product may be configured to determine whether a device is switching from a first radio access technology to a second radio access technology to perform a circuit switched call setup process and determine whether at least one of a circuit switched domain registration procedure and a packet switched domain registration procedure is to be performed on the second radio access technology.

A unified approach multi-mode system selection is provided for a mobile device implementing multiple multi-mode system selection (MMSS). Different system operators may provide their own MMSS databases and rules in different frameworks. To allow a mobile device to perform MMSS without modifying its software, the different databases may be mapped into a common database. In one example, an MMSS solution is implemented that uses a Preferred Roaming List (PRL) database according to a 3GPP2 system selection to specify the prioritization of 3GPP and 3GPP2 systems the mobile device. When the mobile device is powered up, the information in the different MMSS databases is mapped into a common database (“PRL with PLMN records”). The wireless communication device then acts on this information in the common database to perform system selection.

Systems and methodologies are described herein that facilitate data session suspend control in a multi-radio wireless communication system based on user equipment capability. As described herein, various techniques are provided herein whereby a wireless communication network with which a user device communicates can suspend a data session and/or other communication session associated with the user device upon identifying that the user device has moved to a disparate communication network based on the transmitter/receiver capabilities of the user device. In one example herein, a mobility management entity and/or other network management entity can determine whether to perform suspend control based on an event notification from another network based on user capability. In another example herein, a network to which a user device moves can determine whether to send an event notification to another network associated with the user device based on capabilities of the user device.
