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.
