Abstract: Disclosed are an information processing method of a multimode terminal, a multimode terminal and an access network device, wherein, a multimode terminal negotiates with an HRPD access network to determine to close a session keep-alive message initiated by the HRPD access network, the HRPD access network does not transmit a session keep-alive request message to said terminal after said terminal is switched to an LTE network from an HRPD network; and/or after negotiating to determine to close a session keep-alive message initiated by said terminal, said terminal does not transmit a session keep-alive request message to the HRPD network after being switched to the LTE network from the HRPD network. Said terminal acquires a dedicated priority of the HRPD and/or the LTE network from the HRPD access network, and performs network reselection in an idle state according to the dedicated priority when meeting an enabled condition of the dedicated priority.

Abstract: A wireless device performs a transmission on a primary and auxiliary access channels to enable reception by at least three base stations. The base stations perform a measurement on the received transmission, e.g., a time of arrival of the transmission. The base stations report their measurements to a position determination entity. The position determination entity estimates geographic position of the wireless device. One method used by the position determination entity includes tri-lateralization based on the received measurement reports.
