Description

The present invention relates to the field of mobile communications technologies, and in particular, to a terminal state transition method and a mobile terminal. BACKGROUND As a new 3G standard, Worldwide Interoperability for Microwave Access (WiMAX) has become a hot spot for global telecom operators and equipment manufacturers, and it has an advantage in the field of wireless broadband. Since the terminal (Mobile Station, MS for short) is powered by a battery, power saving management is one of the focuses of the WiMAX standard. In order to enable the mobile station to use different power saving mechanisms according to different service states, the 802.16 series protocol gives a status classification of the service, and FIG. 1 is an IEEE state transition diagram of IEEE802.16m. As shown in Figure 1, the IEEE 802.16m MS consists of four states: Initialization Sate, Access Sate, Connected Sate, and Idle Sate; In the initialization state, the main work done by the MS is to scan and select the base station (if one scan and selection is unsuccessful, it will continue to stay in the initialization state for scanning and hanging), and after successfully selecting the base station and entering the access state, obtain System Configuration Information (Configuration Information). When the MS is in any other state, if an abnormal condition (Abnormal Operation) occurs and cannot continue in this state, the MS can transition from any state to an initialization state. The access status means that after the MS successfully selects the base station, it enters the network through the following processes: uplink and downlink synchronization, communication capability, authentication, authorization and authorization, registration process, and finally the MS interacts with the base station. Assign to an IP address and establish at least one connection to convert to a connected state. If an abnormal operation occurs during the above process, the MS will return to the initialization state. The above two states are the "instantaneous, state" that the MS must go through during the network access process. After the MS enters the network, it will be in the last two states for a long time: the connection state and the idle state, and these two states are the key to the MS power saving. ^ I am the state. As shown in Figure 2, the connection status includes three sub-modes: Sleep Mode, Active Mode, and Scanning Mode; In the active mode, the MS and the base station perform normal operations to complete downlink (downlink, DL for short)/uplink (uplink, UL for short) traffic transmission between the MS and the base station. Before entering the sleep mode, the MS determines the specific power saving type in the sleep mode through the sleep mode signaling interaction sent by the base station, and then enters the sleep mode in which the sleep interval (Listing Interval) and the listening interval (Listing Interval) alternate. During the sleep interval, the MS neither sends nor receives communication traffic from the base station to the base station; receives an indication message within the listening interval, determines whether the MS needs to be converted into the active mode, or maintains the sleep mode based on the content of the indication message, During the sleep interval, MS may choose to convert to active mode. In scan mode, the MS performs a search operation and may be temporarily in an invisible state (Unavailable). In the active mode, the MS can be converted into a search mode by interacting with a Media Access Control (MAC) signaling of the base station (which can be a MOB SCN-REQ/RSP message). During the scan interval, the MS is invisible to the serving base station (Unavailable). As shown in Figure 2, each time the MS re-enters the connected state, it will inevitably enter the active mode first, and then enter the sleep mode or scan mode again through signaling interaction and negotiation. The idle state is a state that can be entered when the MS has no data for a long time. The idle state consists of two separate modes: paging available mode and paging unavailable mode. In the non-available mode, some circuits of the MS can be turned off, which effectively saves energy. During the idle state, the MS can achieve power savings by switching between the paging available mode and the paging unavailable mode. Specifically, the MS performs the connection state in the following three situations: 1. When the MS boots into the network, the MS transitions from the initial state to the connected state via the access state, and directly enters the active mode in the connected state, and then, according to the MS. The request may enter the sleep mode or go into the idle state. 2. When the MS has a handoff, it is assumed that the MS is already in the connected state before the handover. After the handover, the MS enters the access state and then switches the connection state (the switch is generally heavy) Into the network;), or directly from the connection state before the switch to the connection state under the new base station connection (fast re-entry network;); Third, the MS occurs other abnormal operations, the MS believes that the original connection state can not be maintained, re-initialization state Return to the original connection state again and enter the active mode of the connection state. In the above three cases, if the MS is in the sleep mode in the connected state, because the switchover or abnormality must re-enter the connection state, then according to the process setting, the MS must first enter the active mode in the connected state, and then pass the signaling. Enter sleep mode after interaction. Energy is wasted while waiting for the signaling interaction to complete returning to sleep mode. If the MS enters the active mode in the connected state after the initialization and network access, the process of waiting for the signaling interaction of the hibernation request is completed, and then enters the sleep mode. Similarly, the time spent waiting for signaling interactions can also result in wasted energy. SUMMARY OF THE INVENTION In view of this, the present invention provides an improved MS state transition method and a mobile terminal for solving the above-mentioned problem of waste of energy in the prior art. According to an aspect of the present invention, a terminal state transition method is provided, including: a terminal transitioning from a current state to a mode in a part or all of a connection state according to received control signaling from a base station, The status includes at least one of the following modes: sleep mode, active mode, and scan mode.

According to still another aspect of the present invention, a terminal state transition method is provided, including: a mode of a part or all of a connection state before a handover according to a received control signaling from a base station by a terminal. Converted to the same mode as the pre-switching mode or a different other mode in the connected connection state, the connection state includes at least one of the following modes: a sleep mode, an active mode, and a scan mode. According to another aspect of the present invention, there is provided a mobile terminal that switches from a current state to one of a part or all of a connected state according to received control signaling from a base station, a connection state Includes at least one of the following modes: Sleep mode, Active mode, and Scan mode. With the above at least one solution of the present invention, the MS can directly switch from the access state to one of the connected states under the control of the base station; the MS can directly switch from the access state to the sleep state in the connected state when needed.

When the MS is booted into the network, etc., when the MS needs to transition from the access state to the connected state, it first enters the active mode of the connected state, and then transitions from the active mode to the sleep mode. In this process, the MS waits for the signaling interaction to be completed, thereby causing energy. waste. In the embodiment of the present invention, when the MS is booted into the network and the like, the MS needs to be switched from the access state to the connected state, under the control of the base station, The previous state transitions to one of the connected states. In the description of the present specification, one of the connection states refers to one of some or all of the connected states; the mode in the connected state includes at least one of the following modes: sleep mode, active mode, and scanning mode. For example, the MS can transition directly from the current access state to a sleep mode or an active mode in the connected state. During the handover, that is, during the handover from the serving base station to the target base station, the terminal remains in the connected state, wherein the mode in which the terminal can maintain the connected state does not change, or the mode of the connected state changes. Moreover, in the embodiment of the present invention, if the MS needs to transition from the connected state to the idle state, the MS may directly switch from the mode of the connected state to the idle state under the control of the base station, without going through the sleep mode to The process of active mode to idle state. The embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The preferred embodiments of the present invention are described in the following with reference to the accompanying drawings, which are intended to illustrate and illustrate the invention. According to an embodiment of the present invention, a method for terminal state transition is first provided, and the method is used to control a MS to switch to a connected state. The MS state transition method according to the embodiment of the present invention includes: when it is required to switch to the connection state, the MS transitions from the current state to a certain mode in the connected state according to the received control signaling from the base station. Here, the certain mode refers to one of some or all of the connected states; wherein the connected state includes at least one of the following three modes: a sleep mode, an active mode, and a scan mode. In this embodiment, when the MS is booted into the network or the like, and the MS needs to be switched from the access state to the connected state, under the control of the base station, the current state may be switched to one of the connected states; for example, the MS may be The current access state transitions directly to sleep mode or active mode in the connected state. Preferably, the MS transitions from the current state to the sleep mode in the connected state, so that the signaling interaction and time from the active mode to the sleep mode can be reduced, thereby avoiding energy waste of the MS during the period and saving energy of the MS battery. Specifically, the MS may send a message to the base station according to its own needs, requesting to switch from the current state to a certain mode in the connected state. After receiving the request message, the base station sends a response message carrying the control signaling to the MS. The method is as follows: Step 1: The MS sends a request message to the base station, where the request message carries a terminal request state transition mode. Step 2: The base station sends the foregoing control signaling to the MS. In a specific implementation process, the base station may carry the control signaling in a message sent to the MS, and after receiving the message, the MS parses the message to obtain the control signaling, so as to be converted under the control of the control signaling. A mode specified by control signaling to the connected state. Alternatively, the base station actively sends the foregoing control signaling to the MS. Specifically, the base station may send the foregoing control signaling to the MS in the response message of the ranging message after receiving the ranging request message sent by the MS. The method is as follows: Step 4: 1: The measurement request message sent by the terminal to the base station; Step 4: 2: The base station returns a measurement response message to the MS, where the measurement response signal carries the above control signaling . In the specific implementation process, the MS transitions to the connection state includes the following three situations: 1. When the MS is powered on, the MS will transition from the initial state to the connected state through the access state. 2. When the MS encounters other abnormal operations, the MS considers that Maintain the original connection state and re-recover from the initialization state to the connection state again. 3. When the MS is handed over, it is assumed that the MS is in the connected state under the serving base station before the handover, and the MS enters the access after switching to the target base station. The state re-switches the connection state (generally re-enters the network after switching;), or directly converts from the connection state before the handover to the connection state under the connection of the new base station (fast re-entry network;); in the above three cases, the first case, In the former case of the second case and the third case, the MS is switched from the access state to the connected state, and in the third case, before the handover, the connection state is maintained, and the MS maintains the connection state during the handover process. The following three cases are described separately. Access Status 1 > Connection Status

In the embodiment of the present invention, the MS is based on the base station when the MS is switched from the access state to the connected state. The foregoing control signaling that is sent is switched from the current access state to a certain mode in the connected state, and specifically, may be an active mode or a sleep mode. If the MS transitions from the current access state to the sleep mode in the connected state, the above control signaling sent by the base station, or the control signaling between the base station and the MS, determines or negotiates the sleep parameter required by the sleep mode. . The embodiment of the present invention can directly switch from the access state to the sleep mode in the connected state, thereby avoiding an active mode that must first transition from the access state to the connected state, and then transitioning from the active mode of the connected state to the sleep state of the connected state. The process of the pattern. Here, a certain mode refers to one of some or all of the connected states; wherein the connected state includes at least one of the following modes: a sleep mode, an active mode, and a scan mode. FIG. 3 is a schematic diagram of the MS entering the connected state from the access state. As shown in FIG. 3, the MS can be directly switched from the access state to the sleep mode or the active mode in the connected state. Connection state 1>Connection state In this case, the MS switches between cells, and after switching to the next cell, it can be directly switched to one of the connected states by a certain mode in the connected state before the handover. The mode, specifically, may be an active mode or a sleep mode. The switched mode may be the same mode as the pre-switching mode or different other modes. Here, a certain mode refers to one of some or all of the connected states; wherein the connected state includes at least one of the following modes: a sleep mode, an active mode, and a scan mode. Specifically, after the handover, the MS can directly switch from the connection state under the handover base station to the connection state under the connection of the new base station, that is, the fast re-entry network is used, and the terminal maintains the connection state during the handover process; In this case, the MS currently in the connected state can enter the same mode or different other mode as the pre-switching mode in the post-switching connected state by one mode in the pre-switching connected state, that is, the connection state can be maintained. The mode below is unchanged, and the mode in the connected state can also be changed. If the sleep mode is the connected state before the switchover, the sleep mode of the current connection state may be maintained during the handover process, or may be transferred to the active mode in the connected state, if the MS transitions from the active mode before the handover to the sleep after the handover. In the mode, the sleep parameter in the sleep mode of the terminal is determined or negotiated by the control signaling or the control signaling between the MS and the base station. If the sleep mode is the sleep mode before the MS switchover, the MS and the base station are in the mode. The sleep mode listening window completes the required control signaling or control signaling interaction. Specifically, as shown in FIG. 4; in FIG. 4, the MS can keep the sleep mode of the current connection state unchanged or directly switch to the active mode in the connected state. The specific conversion to which mode is required can be determined by the MS according to its own needs. If the active mode of the connection state is before the handover, the MS can maintain the active mode of the current connection state or the sleep mode of the connection state, as shown in FIG. 5; in FIG. 5, the MS can maintain the current connection state. The active mode is unchanged or directly transitions to the sleep mode of the connected state. The specific mode that needs to be switched to can be determined by the MS according to its own needs. Moreover, when an abnormal re-entry occurs, the MS can enter the initialization state from the connected state. According to the foregoing MS state transition method provided by the embodiment of the present invention, the process of signaling interaction can be reduced, the time of state transition can be shortened, and the energy of the MS battery can be saved. Connection State 1 - Idle State According to an embodiment of the present invention, another MS state transition method is also provided, which is used to control the MS to exit the connection ^! state. The MS state transition method according to an embodiment of the present invention includes: the MS in the connected state transitions from the sleep mode or the active mode in the connected state to the idle state according to the received control signaling from the base station. The MS in the connected state can enter the idle state when there is no data transmission and reception. Specifically, similar to the first MS state transition method described above, the base station can actively send the foregoing control signaling to the MS, or after receiving the request of the MS. And sending the foregoing control signaling to the MS. Therefore, the method may include the following steps: Step 1: The MS receives control signaling from the base station, where the control signaling is used to indicate that the MS is in a sleep mode from the connected state. Or the active mode transitions to the idle state; Step 2: The MS directly switches from the sleep mode or the active mode in the current connected state to the idle state under the control of the above control signaling. In a specific implementation process, the base station may actively carry the foregoing control signaling in the message sent to the MS; when it is required to transition from the connection state to the idle state, the MS may also actively send a message to the base station to request to switch from the connection state according to its own needs. After receiving the request message of the terminal, the base station carries the control signaling in the response message sent to the MS, and after receiving the message sent by the base station, the MS parses the control signaling, according to the control signaling. , directly transition from the sleep mode or active mode in the current connected state to the idle state. If the mode in the current connected state is the sleep mode, the MS can directly transition from the sleep mode to the idle state, thereby reducing the Sleep mode to active mode, then signaling interaction and time from active mode to idle state. Specifically, the MS can directly switch from the active mode or the sleep mode in the current connected state to the idle state. FIG. 6 is a schematic diagram of the MS exiting from the sleep mode or the active mode of the current connected state according to the embodiment of the present invention. When the MS exits the current connection state, it can exit from the sleep mode or the active mode of the current connection state, that is, the MS can directly enter the idle state (IDLE) from the active mode or the sleep mode. When the MS directly enters the idle state from the sleep mode, the MS and the base station complete the required control signaling or control signaling interaction in the listening window of the sleep mode. When an abnormal re-entry occurs, the MS can enter the initialization state from the connection state. According to the foregoing MS state transition method provided by the embodiment of the present invention, the MS can be directly switched from the sleep mode to the idle state without performing the sleep mode-active mode-idle state process, saving signaling overhead and reducing the MS. Energy consumption. In addition, if the MS is in the scan mode in the connected state, when it is necessary to switch from the scan mode to the idle state in the connected state, there are two ways as follows: Method 1: After the scan time is terminated, the terminal is connected from the state The scan mode is transferred to the active mode in the connected state; after receiving the control signaling of the base station, the active mode is switched from the active mode to the idle state; mode 2, after receiving the control signaling of the base station, the terminal is connected from the connected state The next scan mode shifts to the idle state. According to the foregoing MS state transition method provided by the embodiment of the present invention, the MS can be directly transferred from the scan mode to the idle state without performing the scan mode-active mode-idle state process, saving signaling overhead and reducing the MS. Energy consumption. According to an embodiment of the present invention, another MS state transition method is further provided, where the method is used to control an MS to maintain a connection state during a handover process, where the connection state includes at least one of the following modes: a sleep mode, an active mode, Scan mode. The MS state transition method according to the embodiment of the present invention includes: in the handover process, the terminal converts from a mode in the connection state before the handover to a state in the connection state after the handover according to the received control signaling from the base station. A certain mode. The switched mode may be the same mode as the pre-switching mode or different other modes. Here, one mode refers to one of some or all of the modes in the connection state; wherein the connection state includes at least one of the following modes: sleep mode, active mode And scan mode. Specifically, if the sleep mode is in the connected state before the terminal is switched, the MS can maintain the sleep mode in the current connection state or the active mode in the connected state during the handover process, if the MS maintains the current connection. The sleep mode in the state is unchanged, and the MS and the base station complete the required control signaling or control signaling interaction in the listening window of the sleep mode, and may also pass the control signaling or control signal between the MS and the base station. Let the interaction change the sleep parameter in the sleep mode of the terminal, as shown in Figure 4; if the active mode is in the connected state before the terminal is switched, the MS can maintain the active mode of the current connected state during the switching process, and can also be converted. In the sleep mode in the connected state, if the MS transitions from the active mode in the current connected state to the sleep mode in the connected state, the MS may interact with the control signaling or control signaling between the base station to determine or negotiate the MS. The sleep parameters in sleep mode are shown in Figure 5. Specifically, the base station may actively control the MS to maintain the connection state during the handover process, and may also control the MS to maintain the connection state during the handover process after receiving the request of the MS. In the actual communication process of WiMAX, since the essence of WiMAX technology is based on space resource sharing, whether it is signaling interaction or data transmission, it is intermittent in time, and no site needs to be in active mode. The sleep mode and the active mode may be merged into a sleep mode, and the sleep mode includes a sleep window and a listening window. When any station enters the connection state, it automatically enters a mode in which the sleep window and the monitor window alternate, and the sleep mode may also be referred to as a connection. The mode, such as the connection state, includes: sleep mode or / and scan mode. Based on the above-described connection state including the sleep mode or/and the scan mode, another MS state transition method is also provided according to an embodiment of the present invention. The MS state transition method according to the embodiment of the present invention includes: when it is required to transition from the other state to the connected state, the MS transitions to the sleep mode in the connected state according to the received control signaling of the base station. FIG. 7 is a schematic diagram of state transition of an MS according to an embodiment of the present invention. As shown in FIG. 7, the MS may directly switch from an access state to a sleep mode in a connected state during initial access or re-entry, or the MS may switch. In the process, directly switching from the connection state before the handover to the sleep mode in the connected state after the handover, when the MS transitions from the current access state to the sleep mode in the connected state, through the control signaling between the MS and the base station or Controlling signaling interaction, determining or negotiating a sleep parameter in the sleep mode; and, when the MS in the connected state has no data to send and receive, may enter an idle state, The MS can directly switch from the current sleep mode to the idle state; or when the switchover, the terminal maintains the sleep mode of the connected state unchanged; and enters the initialization state when an abnormal re-entry occurs. Similarly, the base station may actively send the foregoing control signaling to the MS, or may send the foregoing control signaling to the MS when receiving the request of the MS. In the embodiment of the present invention, signaling interaction required for unnecessary state transition can be reduced, the speed of state transition can be accelerated, and air interface radio resources can be saved. The embodiment of the present invention further provides another MS state transition method, which is used to control the MS to maintain the connection state during the handover process, based on the case where the foregoing connection state includes the sleep mode or the scan mode. The MS state transition method according to the embodiment of the present invention includes: in the handover process, the MS converts from a certain mode in the connection state before the handover to the connection state after the handover according to the received control signaling from the base station. One of the modes below. The switched mode may be the same mode as the pre-switching mode or different other modes. Here, one of the modes in the connected state refers to one of some or all of the following modes: sleep mode, scan mode. Specifically, the MS can switch from the sleep mode before the switch to the sleep mode after the switch, as shown in the figure.

As shown in Fig. 8, before switching, the MS is in the sleep mode in the connected state. After the switchover, the MS continues to maintain the sleep mode in the connected state. When the MS maintains the sleep mode during the handover, the MS and the base station send control signaling or perform control signaling interaction in the listening window of the sleep mode, and the MS and the base station may also change the sleep by using the control signaling or the control signaling interaction. Sleep parameters in mode. Based on the foregoing, the connection state includes only the sleep mode and the scan mode. The embodiment of the present invention further provides another method for MS state transition, where the method is used to control the MS to exit the connection state. According to the embodiment of the present invention, the MS state transition method includes: when it is required to transition from the connected state to the idle state, the MS transitions from a mode in the current connected state to an idle state according to the received control signaling from the base station. Here, one of the modes in the connected state refers to one of some or all of the following modes: sleep mode, scan mode. Specifically, the MS can directly switch from the sleep mode in the current connected state to the idle state. As shown in FIG. 9, the MS enters the idle state from the sleep mode in the connected state. In this case, the MS and the base station are in the sleep mode. The listening window sends the above control signaling or performs control signaling interaction.
