Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The embodiment of the present invention effectively combines the terminal power-saving technology with the LBS technology. After the terminal successfully accesses the AP, the AP sends the terminal a sleep policy identifier related to the location information of the AP, so that the terminal performs operator-controlled sleep strategy. Through the embodiment of the present invention, the sleep policy of the terminal can be dynamically adjusted according to the different areas where it is located, so as to ensure that the operator can provide more effective LBS services for the terminal through the Wi-Fi technology.

Figure 1 shows the implementation process of the method for controlling the terminal sleep policy provided by the embodiment of the present invention, wherein the execution subject of the process is the terminal, and the implementation process of Figure 1 is described in detail as follows:

In S101, a terminal establishes a WLAN connection with an AP.

When the terminal enters the signal range of the AP, it can search for the Service Set Identifier (English: ServiceSet Identifier, abbreviation: SSID) and signal strength of the AP. The terminal selects the AP and sends an access request to the AP to establish an AP. WLAN connection to this AP.

In this embodiment, after the terminal establishes a WLAN connection with the AP, in the fat AP scenario, the terminal can communicate and interact with the AP to complete identity authentication and IP address assignment, or, in the thin AP scenario, The terminal can communicate and interact with at least one of the access controller (English: Access Controller, abbreviated: AC) and the broadband access server (English: Broadband Remote Access Server, abbreviated: BRAS) through the AP to complete identity authentication and IP address assignment.

At the same time, in a scenario that supports terminal mobility, after the mobile terminal switches APs and successfully establishes a connection with the switched AP, it does not need to re-execute identity authentication and IP address allocation related operations. Wherein, the scenario of terminal mobility refers to that the terminal will not be dropped or redial during the moving process.

In S102, the terminal receives a sleep strategy identifier sent by the AP, where the sleep strategy identifier is determined based on the location information of the AP.

In this embodiment, the sleep strategy identifier may be preset in the AP, and the sleep strategy identifier is related to the location of the AP. For example, a merchant in location A wants to push advertisements on the terminal at 12:00 noon every day. By purchasing related LBS services from the operator, he can set the corresponding sleep policy flag on the AP in location A. The sleep policy corresponding to the policy identifier can activate the terminal to enter the active state at 12:00 noon every day to complete the push of advertisements.

On the one hand, the sleep policy ID can be sent to the terminal separately by the AP after establishing a connection with the terminal; on the other hand, in the fat AP scenario, the sleep policy ID can also communicate and interact between the terminal and the AP to complete identity authentication and IP authentication. During the process of address allocation, it is carried in a certain attribute value of the AP's authentication response to the terminal and sent to the terminal.

For the sleep strategy identifier, it can also exist in the form of AP attribute information such as SSID or LBS information of the area where the AP is located. Regardless of the form of the sleep strategy identifier, each sleep strategy identifier will correspond to a sleep strategy.

In this embodiment, after receiving the sleep policy identifier sent by the AP, the terminal may return a confirmation message indicating successful reception to the AP, so that the AP can know in time that the sleep strategy identifier is sent successfully. If the AP does not receive the confirmation message returned by the terminal within a period of time, it can be determined that the sleep policy ID has not been sent successfully. After that, the AP can automatically resend the sleep policy ID to the terminal according to the policy, or after receiving the resend request from the terminal Then resend the sleep policy identifier to the terminal.

In S103, the terminal acquires a sleep strategy corresponding to the sleep strategy identifier.

Since different sleep strategy identifiers correspond to different sleep strategies, after obtaining the sleep strategy identifier sent by the AP, the terminal can obtain the sleep strategy related to the location information of the area where the AP is located through the sleep strategy identifier. Obviously, the sleep policy is also related to the location information of the current area where the terminal is located, thereby achieving the purpose of dynamically adjusting the sleep policy of the terminal according to the different areas where the terminal is located.

On the one hand, the terminal can locally store sleep strategies corresponding to each sleep strategy identifier, and after obtaining the sleep strategy identifier sent by the AP, match the obtained sleep strategy identifier in the local strategy library of the terminal to Obtain the sleep strategy corresponding to the sleep strategy identifier; on the other hand, the sleep strategy can also be stored on the server in the network, and the sleep strategy corresponding to each sleep strategy identifier is stored on the server, when the terminal obtains the AP sends After the sleep policy ID, it will establish communication with the server, and send the acquired sleep policy ID to the server, and the server will match the received sleep policy ID in the local policy library, and obtain the sleep policy ID corresponding to Sleep policy and send it to the terminal.

In the embodiment of the present invention, the storage function of the sleep policy may be integrated in the network elements of the existing radio frequency system, and set together with the existing network elements. For example, the sleep policy is stored in an existing policy server. Hereinafter, for convenience of description, the server storing the sleep policy is collectively referred to as a sleep policy server.

In the sleep policy acquired by the terminal, various sleep policy parameters that the terminal needs to execute currently are specified, including but not limited to at least one of the following: sleep cycle, activity duration, and activity time. Among them, the sleep period indicates the length of time between the moment when the terminal enters the current sleep state and the moment when it enters the next sleep state; the activity duration indicates that the terminal is in an active state (ie, non-sleep state) during a sleep cycle of the terminal The length of time; the active moment indicates the time point when the terminal enters the active state in one of its sleep cycles.

Further, the sleep strategy parameters may also include at least one of the following: the longest sleep period, the shortest activity duration and the mandatory activity time. Among them, the longest sleep period indicates the maximum length of time that the terminal is allowed to stay in the sleep state. After the longest sleep period is indicated, even if the terminal does not currently have any business, it must enter the active state after the longest sleep period arrives. , to receive data; the minimum active time indicates the shortest time that the terminal is in the active state, and the minimum active time is specified to ensure the time for the terminal to receive data in real time; the mandatory active time is used to force the terminal to be in the active state at a certain moment. When the activity time comes, if the terminal is in the sleep state, it must switch from the sleep state to the active state for data reception. The minimum activity duration is stipulated, which can realize the timing wake-up of the terminal, which is conducive to the deployment of multicast or broadcast message push.

In S104, the terminal executes the acquired sleep policy.

In this embodiment, after the terminal obtains the sleep strategy, it starts to execute the sleep strategy. During the execution of the sleep strategy, the terminal needs to send a power saving control message to the AP. The power saving control message includes but is not limited to the following: Types: sleep indication, activity indication, and fetch cache data indication. Among them, the sleep indication is sent when the terminal enters the sleep state from the active state, and is used to inform the AP that the terminal will be in the sleep state for a period of time, and the AP will know that during this period of time, when there is data sent to the terminal , the data needs to be cached; the activity indication is sent when the terminal enters the active state from the sleep state, and is used to inform the AP that the terminal will be active in the next period of time, and the AP will know that during this period of time, when there is When sending data to the terminal, there is no need to cache the data, but can directly send the data to the terminal; the cached data indication is sent when the terminal is active, and is used to inform the AP that the terminal is in sleep In the state, the cached data sent to the terminal is delivered to the terminal.

In addition, when a sleep policy server is set up in the network, the work of data caching is performed by the sleep policy server. Compared with the method of caching data by the AP, in the current situation, when the AP receives the sleep instruction of the terminal, The sleep instruction will be notified to the sleep policy server, and the sleep policy server will know that within this period of time, when there is data sent to the terminal, the data needs to be cached; when the AP receives the terminal's activity indication , the activity indication will be notified to the sleep policy server, and the sleep policy server will know that within this period of time, when there is data sent to the terminal, it does not need to cache the data, but can directly download the data to the terminal; when the AP receives the cache data acquisition instruction from the terminal, it will notify the sleep policy server of the cache data acquisition instruction, and then the sleep policy server will send the information cached when the terminal is in the sleep state to the terminal. The data of the terminal is sent to the terminal. By notifying the sleep policy server of the status of the terminal by the AP, the sleep policy server can perceive the status of the terminal in real time and provide an interface for querying or notifying the status of the terminal to facilitate third-party query and understanding. The data sent to the terminal when the terminal is in the sleep state is cached by the sleep policy server instead of the AP, which can better realize fine-grained cache and push of data.

In combination with the embodiment shown in FIG. 1 , FIG. 2 shows the implementation process of the terminal sleep policy control method provided by the embodiment of the present invention, wherein the execution subject of the process is the AP that establishes a WLAN connection with the terminal. The implementation process in FIG. 2 The details are as follows:

In S201, the AP establishes a WLAN connection with the terminal.

When the terminal enters the signal range of the AP, it can search for the SSID and signal strength of the AP. When the terminal selects the AP, the AP receives the access request sent by the terminal to establish a WLAN connection with the terminal.

In this embodiment, when in the application scenario of a fat AP, after the terminal establishes a WLAN connection with the AP, the AP needs to communicate and interact with the terminal to complete identity authentication and IP address assignment for the terminal.

In S202, the AP sends a sleep strategy identifier to the terminal, where the sleep strategy identifier is determined based on the location information of the AP, so that the terminal acquires and executes a sleep strategy corresponding to the sleep identifier.

On the one hand, the sleep policy ID can be sent to the terminal separately by the AP after establishing a connection with the terminal; on the other hand, in the fat AP scenario, the sleep policy ID can also communicate and interact between the terminal and the AP to complete identity authentication and IP authentication. During the process of address allocation, it is carried in a certain attribute value of the AP's authentication response to the terminal, and then sent to the terminal.

In this embodiment, after receiving the sleep policy identifier sent by the AP, the terminal may return a confirmation message indicating successful reception to the AP, so that the AP can know in time that the sleep strategy identifier is sent successfully. If the AP does not receive the confirmation message returned by the terminal within a period of time, it can be determined that the sleep policy ID has not been sent successfully. After that, the AP can automatically resend the sleep policy ID to the terminal according to the policy, or after receiving the resend request from the terminal Then resend the sleep policy identifier to the terminal.

In this embodiment, after the terminal obtains the sleep strategy, it starts to execute the sleep strategy. During the execution of the sleep strategy, the terminal needs to send a power saving control message to the AP. The power saving control message includes but is not limited to the following: Types: sleep indication, activity indication, and fetch cache data indication. Among them, the sleep indication is sent when the terminal enters the sleep state from the active state, and is used to inform the AP that the terminal will be in the sleep state for a period of time, and the AP will know that during this period of time, when there is data sent to the terminal , the data needs to be cached; the activity indication is sent when the terminal enters the active state from the sleep state, and is used to inform the AP that the terminal will be active in the next period of time, and the AP will know that during this period of time, when there is When sending data to the terminal, there is no need to cache the data, but can directly send the data to the terminal; the cached data indication is sent when the terminal is active, and is used to inform the AP that the terminal is in sleep In the state, the cached data sent to the terminal is delivered to the terminal.

In addition, when a sleep policy server is set up in the network, the work of data caching is performed by the sleep policy server. Compared with the method of caching data by the AP, in the current situation, when the AP receives the sleep instruction of the terminal, The sleep instruction will be notified to the sleep policy server, and the sleep policy server will know that within this period of time, when there is data sent to the terminal, the data needs to be cached; when the AP receives the terminal's activity indication , the activity indication will be notified to the sleep policy server, and the sleep policy server will know that within this period of time, when there is data sent to the terminal, it does not need to cache the data, but can directly download the data to the terminal; when the AP receives the cache data acquisition instruction from the terminal, it will notify the sleep policy server of the cache data acquisition instruction, and then the sleep policy server will send the information cached when the terminal is in the sleep state to the terminal. The data of the terminal is sent to the terminal.

Through the embodiments shown in Fig. 1 and Fig. 2 of the present invention, the sleep strategy of the terminal is determined by the location information of the area where the AP it accesses is located. Once the terminal moves and switches the AP, the sleep strategy it executes will also be based on the The current access AP is dynamically adjusted according to the location of the different areas, thus realizing the effective combination of terminal power saving technology and LBS technology, ensuring that the sleep strategy executed by the terminal is controllable by the operator, so as to ensure that the operator can use Wi- Fi technology provides more effective LBS services for terminals.
