This application is a is a continuation of U.S. application Ser. No. 15/485,668, filed on Apr. 12, 2017, now pending, which is a continuation of U.S. application Ser. No. 14/551,441, filed Nov. 24, 2014, now U.S. Pat. No. 9,736,879, issued Aug. 15, 2017, which is a continuation application of International Application PCT/JP2012/063818, filed on May 29, 2012 and designating the U.S., the entire contents of each are incorporated herein by reference.
1. A wireless communications system comprising: a base station; and a wireless station, wherein the base station transmits to the wireless station, after receiving a first signal of Radio Resource Control (RRC) protocol from the wireless station, a second signal of RRC protocol including information related to a timing of transition to a first state of RRC protocol, and the wireless station transitions to the first state according to the information related to the timing and included in the second signal, and upon transition from the first state to a second state other than the first state, stores a parameter related to wireless communication and used in the first state.
2. A wireless station comprising: a transmitter that transmits a first signal of Radio Resource Control (RRC) protocol to a base station; a receiver that receives, after the first signal is transmitted, a second signal of RRC protocol including information related to a timing of transition to a first state of RRC protocol; a controller capable of controlling transition to the first state of RRC protocol according to the information related to the timing and included in the second signal; memory capable of storing, upon transition from the first state to a second state of RRC protocol other than the first state of RRC protocol, a parameter related to wireless communication and used in the first state.
3. The wireless station according to claim 2, wherein in the first state of RRC protocol, the controller performs control so as to enable the transmitter to transmit user data.
4. The wireless station according to claim 3, wherein in the second state of RRC protocol, the controller performs control so as not to enable the transmitter to transmit the user data.
5. The wireless station according to claim 2, wherein the controller controls transition to the first state according to the information related to the timing, when controlling the transition to the first state by a first method of state transition, and controls the transition to the first state in a manner different from the first method of state transition, when controlling the transition to the first state by a second method of state transition.
6. The wireless station according to claim 5, wherein the controller controls the transition to the first state by the first method of state transition or the second method of state transition according to a moving state of the wireless station.
7. The wireless station according to claim 2, wherein the memory stores as the parameter related to the wireless communication, at least one of a wireless parameter and a security parameter that are used in the first state.
8. The wireless station according to claim 2, wherein the controller causes the memory to store the parameter related to the wireless communication, and upon transition to the first state, applies the parameter related to the wireless communication to a parameter used for communication.
9. The wireless station according to claim 2, wherein the receiver receives a third signal including information for releasing a configuration related to a state transition to the first state.
10. A base station comprising: a receiver that receives a first signal of Radio Resource Control (RRC) protocol from a wireless station; and a transmitter that transmits, after the first signal is received, a second signal of RRC protocol including information related to a timing of transition to a first state of RRC protocol, wherein the receiver receives data transmitted from the wireless station that is in the first state, the wireless station being capable of transitioning to the first state of RRC protocol according to the information related to the timing.
In wireless communications systems, processing is performed at the radio resource control (RRC) layer and includes the configuration, reconfiguration, and release of connections between wireless stations and base stations (for example, refer to Japanese Laid-Open Patent Publication No. 2008-199223 and Published Japanese-Translation of PCT Application, Publication No. 2010-514329). For example, under the 3rd Generation Partnership Project (3GPP), an RRC connected mode (RRC Connected) and a RRC idle mode (RRC Idle) are specified as states of the RRC layer (for example, refer to 3GPP T536.331, "Radio Resource Control (RRC) Protocol Specification", V10.4.0, Release 10, December 2011). The RRC connected mode, for example, is a state in which data communication can be implemented between a wireless station and a base station. The RRC idle mode, for example, is a state in which data communication between a wireless station and a base station is not possible.
