A method and apparatus for that provides a re-entry procedure following a radio frequency outage in a wireless communication network is disclosed. The method includes providing () a entity identification for a base station (-) or a paging controller () to a mobile station () during initial entry of the mobile station to a wireless communication network. The method also includes storing () mobile station context information at an entity corresponding to the entity identification. After a radio frequency outage occurs after the initial entry of the mobile station into the network, a notification is sent () that indicates that the mobile station is re-entering the wireless communication network. Based on the notification that there has been a radio frequency outage, the mobile station context information is obtained () to assist the mobile station to re-enter the wireless communication network.

A method, information processing system, and wireless communication system, initiate a handover scanning procedure with a wireless device. The method includes monitoring a first signal strength measurement () transmitted by a wireless device (). A second signal strength measurement associated with the wireless device () that is measured locally is monitored (). The method also includes determining, in response to monitoring the first signal strength and the second signal strength measurement, if a scan event trigger has been detected (). A scan initiation message is transmitted () to the wireless device () in response to a scan event trigger being detected. The scan initiation message signals the wireless device () to perform handover scanning procedures.

A method is described for providing Hybrid Automatic Repeat Request (HARQ) transmission feedback to a higher layer protocol in a communication system. The method includes a step of detecting HARQ retransmissions in a first layer protocol. This can be used to determine a HARQ failure or an HARQ ACK after a delay of some retransmissions. A next step includes providing feedback information about the detecting step from the first layer protocol to a higher layer protocol. A next step includes instituting corrections at the higher layer protocol, in response to the information transferred from the first layer protocol. These corrections can include immediate retransmission of those bursts of a HARQ failure, or correcting timers to match the delay of eventually ACK'ed data.

HARQ transmission feedback for higher layer protocols in a communication system

A command is received to perform an update operation on a first component of code contained in a plurality of memory blocks in a memory. It is determined whether or not the update operation requires additional space, beyond that which is already allocated to the first component, to complete the operation. A first memory block is located on which to perform the operation if the update operation requires additional space. A second memory block is located, through utilization of a database, to perform the operation if the update operation does not require additional space. The update operation is performed.

Dynamically updateable and moveable memory zones

A system and method is provided for over-the-air updating of a wireless communication device. The system and method provides the ability to update both direct-addressable and non-direct-addressable portions of the device memory. The system and method uses an agent that is downloaded to the wireless communication device as part of a direct-addressable memory update package. The direct-addressable memory update installs the agent into the direct-addressable memory. After the direct-addressable memory update is performed, the agent is executed and performs an update of the non-direct addressable portions of the device memory.

This method () adaptively sends control messages and a predetermined number of fast repeats of the control messages on the traffic channel of a mobile communication system. For a control message which has already been lost (), the system sends the control message again with a first number of fast repeats () if the traffic channel is operating at a full rate; and the system sends the control message with a second number of fast repeats if the traffic channel is operating at a subrate. The number of fast repeats is selectable. If the control message has not been previously sent and the traffic channel is operating at a subrate (), the system will send the control message with a third number of fast repeats ().

Method for adaptive channel signaling

A mobile station typically determines whether to drop a communication link and/or a base transceiver station (BTS) based on a performance of an associated forward link. In order to avoid dropping a communication link that has a weak forward link but a strong reverse link, a communication system is provided that determines whether the reverse link is still good before determining to drop the communication link. In one embodiment, the communication system determines whether reverse link is still good based on a quality metric associated with the reverse link and quality metric(s) associated with one or more other reverse links that are in a soft-handoff mode with reverse link. In another embodiment, the communication system determines whether reverse link is still good by comparing a quality metric associated with the reverse link to a threshold.

Method and apparatus for performing soft-handoff in a wireless communication system

When performing a soft-handoff, a communication system determines whether to engage in an analysis of a reverse link associated with a base station under consideration to be added to an active set of a mobile station (MS). Upon determining not to analyze the reverse link, the communication system adds the base station to the active set without evaluating the associated reverse link. Upon determining to engage in a reverse link analysis, the communication system evaluates the reverse link in order to assure that a communication link is not terminated, or dropped, as part of the soft-handoff until such time as the communication system may confirm that an acceptable quality reverse link is being added. The communication system then determines whether to add the base station to the active set based upon the evaluation.
