摘要： Systems and methodologies are described that facilitate reducing battery consumption during periods of inactivity intermixed with traffic bursts in wireless communications systems. A semi-connected mode is provided that fast recognition of mobile devices upon wakeup and access while enabling mobile devices to operate in reduce power states. A mobile device operates in a semi-connected mode with all base stations in an active set of the mobile device. Moreover, mechanisms are provided to notify mobile devices of pending data while avoiding latency associated with paging channels.

摘要： A method and apparatus for generating a cryptosync is disclosed that generates a cryptosync with the desired variability without the overhead in complexity and size of prior cryptosyncs. The cryptosync is generated from a combination of fields including fields relating to the segmentation and reassembly of the data packets at a transmitting terminal and a receiving terminal. The resultant cryptosync does not repeat during the use of a particular security key.

摘要： Automated PilotPN code conflict resolution using an access point with the assistance of one or more access terminals is disclosed. An exemplary method includes determining a set of access points, as well as determining a set of PilotPN codes used by the set of access points. Detection is then made concerning whether at least two access points of the set of access points have conflicting PilotPN codes. A first PilotPN code is allocated to one of the at least two access points having conflicting PilotPN codes. Additionally, one or more other PilotPN codes, which are distinct from the first PilotPN code, are allocating to remaining access points of the at least two access points having conflicting PilotPN codes. Corresponding apparatus and other exemplary methods are also disclosed.

摘要： An automated neighbor discovery by a base station with the assistance of an access terminal are disclosed. An exemplary method includes receiving a first message from an access terminal based on detecting an identification signal by the access terminal from the first base station in a communication system. Determination whether the first base station is a known base station is then made. If the first base station is not known, a second message is transmitted to the access terminal requesting a network identification of the first base station. A third message from the access terminal is received in response to the second message including the requested network identification. A request for identification data is sent by the second base station to the first base station via a network link based on the network identification. Corresponding apparatus and other exemplary methods are also disclosed.

摘要： A route protocol is established whereby a mobile device can communicate to a multitude of (receiving) base stations though a tunnel created through a serving base station. A message that includes a Route Creation Header can be transmitted by the mobile device to create the tunnel. The Route Creation Header is reviewed by the receiving base station while the mobile device is in a Waiting-To-Open State. Various errors might occur with respect to the Route Creation Header. These errors can be conveyed to the mobile device by base station by setting one or more error code fields. Once the errors are resolved, another attempt to create a tunnel with base station can be made, if desired.

摘要： Methods and apparatus for communicating between an access terminal (AT) and a device serving the AT by way of an Access Point (AP) are described. In accordance with one feature serving devices may be assigned specific addresses which are interpreted based on the source of the communication, e.g., MAC packet, in which the address is used. Such addresses may be interpreted as being of a different type than other addresses which can be interpreted and/or used without taking into account the identity of the sender. In some embodiments Session Controllers and/or Internet Attachment Points (IAPs) are identified with such addresses. The address value is the same for one or more ATs but is interpreted at an AP receiving such the IAP address based on information corresponding to the AT which sent the packet including the IAP or Session Controller address.

摘要： Systems and methods are provided for processing wireless signal components for a mobile wireless access broadband service. This can include processes for defining a protocol that controls whether to invoke a tune away component to determine an alternative wireless communications path. This can include defining one or more tune away parameters for the tune away component. The process can then automatically select the alternative wireless communications path based in part on the tune away procedure and at least one of the tune away parameters.

摘要： Systems and methods of generating quick paging messages having nearly unique identifiers and variable capacity are described. The system generates a quick paging message identifying an access terminal to indicate the presence of a scheduled paging message for that access terminal. The system generates a quick paging notification for each access terminal having a scheduled paging message and generates a compressed nearly unique identifier of each access terminal that is notified in the quick paging message. The compression technique can vary based on the number of bits allocated to the quick paging message as well as the number of access terminals notified in one quick paging message.

摘要： A resource assignment method during a tune-away procedure comprises determining a first instance in time that a tune-away will initiate with respect to an access terminal, determining a second instance in time that corresponds to a latest frame boundary associated with the access terminal prior to the instance in time that the tune-away initiates, and determining resource assignment parameters associated with the access terminal and implementing the resource assignment parameters at the second instance in time. The method can further comprise ceasing communications to the access terminal over a forward link at the second instance in time and discontinuing monitoring reverse link control channels associated with the access terminal at the second instance in time.
