Abstract: An access terminal establishes a session with a first radio access network (RAN). As a result, the access terminal receives a Unicast Access Terminal Identifier (UATI) assigned by the first RAN and establishes configuration settings for radio communications between the access terminal and the first RAN. The access terminal moves from the first RAN to a second RAN. Before the access terminal has a session established with the second RAN, the access terminal receives a request from a user to originate a call. In response, the access terminal sends the second RAN a connection request that includes the UATI assigned by the first RAN. The second RAN evaluates the UATI included in the connection request and determines that it was previously assigned to the access terminal by another RAN. Based on this determination, the second RAN grants the connection request by assigning a traffic channel to the access terminal.

Abstract: During a first time interval, an access point transmits orthogonal frequency division multiplexing (OFDM) signals using a first cyclic prefix length. The access point selects a second cyclic prefix length based, at least in part, on the load of the access point. The access point transmits OFDM signals using the second cyclic prefix length during a second time interval. The load of the access point may be determined based on the amount of downlink data being buffered in the access point for transmission to one or more user devices.

Abstract: Exemplary methods and systems are disclosed herein that may help to dynamically adjust page-transmission power based on the amount of concatenation being applied to a page. An exemplary method involves: (i) before transmission of a page to a mobile station by an access network, the access network identifying any concatenation that is being applied to the page; (ii) based at least in part on the concatenation that is being applied to the page, the access network selecting a page-transmission power for the page; and (iii) the access network transmitting the page to the mobile station at the selected page-transmission power. In an exemplary embodiment, a base station may increase the page-transmission power as the amount of concatenation increases, which may help to improve the paging success rate (PSR) for concatenated pages, among other benefits.

Abstract: A method and system is disclosed for adaptive rate control based on battery life. An access terminal in a wireless communication system that includes a base station will operate in a first state in which, at least, the access terminal responds to receiving reverse-noise messages from the base station by making adjustments to a data transmission rate on a reverse-link traffic channel to the base station in accordance with the received reverse-noise messages. Upon receiving a first threshold number of reverse-noise messages from the base station indicating that the reverse-link noise measured by the base station is alternating above and below the threshold level, and in response having a battery power level below a threshold power level, the access terminal will transition to operating in a second state in which, at least, the access terminal does not make the adjustments to the data transmission rate on the reverse-link traffic channel in response to receiving reverse-noise messages from the base station.
