With continuing reference to fig. 1, the connection between the sta MLD1 and the AP MLD1 may be established by referring to the prior art, and a method for establishing the connection is exemplarily given below.
S1001 and AP MLD1 send broadcast messages through AP1, wherein the broadcast messages comprise link identifications of AP1, AP2 and AP3, indication MLpowersavingsupport of whether multi-link power saving mode capability is supported, and processing timeout duration of the power saving mode. In the embodiment of the invention, the MLpowersavingsupport is set to 1, which indicates that a multilink power saving mode is supported; the power saving mode processing timeout duration is used for indicating the longest processing duration required by the APMLD1 after receiving a power saving request of the terminal device.
It should be noted that, whether the multi-link power saving mode capability indication MLpowersavingsupport and the power saving mode processing timeout duration are supported may be included in the broadcast message, or may be included in other messages, such as a probe response message (e.g., MLproberesponse message) or a connection response message (e.g., association response message); the power saving mode processing timeout period may not be included.
S1002, the STA1 reads the broadcast message sent by the AP1 and obtains the link identifications of the AP1, the AP2 and the AP3.
S1003, STA1 sends a probe request message (e.g. ML probe request message) to AP1, where the message includes link identifiers link1, link2, and link3.
S1004, after receiving the probe request message, the AP1 sends a probe response message (e.g. MLproberesponse message) to the STA1, where the message includes system parameters of the AP1, the AP2, and the AP3 corresponding to the link identifiers link1, link2, and link3.
S1005, STA1 sends a connection request message (e.g., association request message) to AP1, where the message includes operation parameters of STA1, STA2, and STA3 and corresponding operation links, and the embodiment of the present invention sets that STA1 operates on link1, STA2 operates on link2, and STA3 operates on link3.

If the STA MLD1 needs to save power consumption, and the capability parameter MLpowersavingsupport of the connected APMLD1 indicates that a multi-link power saving mode is supported, a logic terminal in an active state in the power saving mode can be determined according to information such as power, signal strength, and the like, other logic terminals are in a sleep state, the logic terminal in the active state is used for normal communication with the APMLD1, including monitoring broadcast messages, receiving data and transmitting data, the logic terminal in the sleep state is in the sleep mode normally, and when there is large data to be transmitted or received, the STA MLD1 can awaken the logic terminal in the sleep state to transmit or receive data autonomously or under the indication of the APMLD1.
Fig. 2 is a schematic diagram of a power saving mode operation method according to an embodiment of the invention. As shown in fig. 2, the power saving mode operation method includes the following steps:
s201, the multi-link terminal equipment STAMLD1 sends a power saving mode enabling message to the multi-link access point equipment APMLD1, and the message indicates enabling of the power saving mode and links in an activated state in the power saving mode. Illustratively, the following parameters are included in the power saving mode enable message:
MLPS mode enabled: whether the power saving mode is enabled, if set to 1, indicates that the power saving mode is enabled; the setting is 0, which indicates that the power saving mode is disabled, and the present embodiment is set to 1. In other embodiments, the parameter may not be included in the power saving mode enable message, and may also indicate that the power saving mode is enabled.
Enabled link bitmap: the link enabling indication, for example, setting a bit corresponding to the link in the active state in the power saving mode to 1, and setting a bit corresponding to the link in the sleep state in the power saving mode to 0, illustratively, setting the value of Enabled link bitmap to 011, which indicates that the links in the active state in the power saving mode are link1 and link2, and link3 is in the sleep state. In some other embodiments, the link identifier may also be directly included to indicate the link in the active state in the power saving mode, for example, if the link identifiers link1 and link2 are included, it indicates that the link in the active state in the power saving mode is link1 and link2, and link3 is in the sleep state.
TID2Link mapping for MLPS mode (optional): and mapping relation between the service in the power saving mode and the link. If the STA MLD1 needs to adjust the mapping relation between the service and the link, namely the mapping relation between the service and the link after the power-saving mode is started is different from the mapping relation between the service and the link in the normal mode, the parameter is included; if the STA MLD1 does not need to adjust the mapping relationship between the traffic and the link, that is, the mapping relationship between the traffic and the link after the power saving mode is enabled is the same as the mapping relationship between the traffic and the link in the normal mode (i.e., before entering the power saving mode), or the STA MLD1 uses the default mapping relationship, the STA MLD1 may not include the parameter. The default mapping relationship in this embodiment refers to that all services are mapped to all links, that is, data of all service types can be transmitted on any link, that is, each link can be used for transmitting data of all service types.
Switch delay (optional): and a delay time for switching to the power saving mode, wherein within a time specified by the parameter, both the terminal device STA MLD1 and the access point device AP MLD1 need to complete related settings of the power saving mode, such as mapping between traffic and a link, sending or receiving unfinished data, and the data is not sent or received on the dormant link after the time specified by the parameter.
Link max idle time (optional): the longest waiting time for keeping the link in the dormant state in the connection state; and starting timing after the link enters dormancy, stopping and resetting if a data transceiving behavior is awakened during timing, regarding the link as disconnected if the link still sleeps after the timing is up, deleting the information of the corresponding logic terminal by the AP MLD1, and simplifying the management of the AP MLD1 on the terminal.
D2A enabled (optional): whether to allow the sleep link to be woken up, such as setting to 1 indicates that the sleep link can be woken up when the wake-up condition is satisfied, and setting to 0 indicates that the sleep link is not allowed to be woken up.
Wake up condition (optional): a condition to wake up a dormant link, such as an amount of data exceeding a specified value; or the error rate of the current activated link is higher than a specified value; or the currently active link transmission delay is above a specified value; or the current active link load is above a specified value; or a combination of one or more of the above.
Preferably, the STA MLD1 transmits the power saving mode enable message to the AP MLD1 through one of the logical terminals through which it is determined that it is in an active state in the power saving mode.
S202, APMLD1 receives a power saving mode enabling message sent by STA MLD1, and sends a power saving mode enabling response message to the STA MLD1, wherein the message indicates whether the power saving mode is enabled or not. Illustratively, the following parameters are contained in the power saving mode enable response message:
MLPS mode enabled: whether the multilink power saving mode is enabled, if set to 1, indicates that the power saving mode is enabled; a setting of 0 indicates that the power saving mode is disabled, and a setting of 1 in this embodiment indicates that the power saving mode is enabled, i.e., indicates that the power saving mode is approved to be enabled. In other embodiments, instead of including the parameter, a Status parameter Status may be included, such as the Status parameter Status being set to 1 to indicate that the power saving mode is allowed, and set to 0 to indicate that the power saving mode is not allowed.
Link2TID mapping for MLPS mode (optional): mapping relation between link and service, if AP MLD1 agrees to the mapping relation indicated in the message of enabling power saving mode, the response message may not contain the parameter; if the AP MLD1 does not agree with the mapping relationship indicated in the power saving mode enable message, the response message includes the parameter for indicating the mapping relationship between the link and the service in the proposed power saving mode.
And S203, the STA MLD1 and the AP MLD1 perform data transmission on the activated link indicated in the power saving mode enabling message according to the determined mapping relation between the service and the link in the power saving mode.
If the power saving mode enabling response message indicates that the power saving mode is not allowed to be enabled, the STA MLD1 does not enable the power saving mode, otherwise, the STA MLD1 and the AP MLD1 may transmit data according to the following method:
and if the AP MLD1 agrees to the mapping relationship between the service indicated in the power saving mode enabling message and the link, the STA MLD1 and the AP MLD1 perform data transmission on the link in the activated state indicated in the power saving mode enabling message according to the mapping relationship between the service indicated in the power saving mode enabling message and the link. If the power saving mode enabling message contains a parameter TID2Link mapping for MLPS mode, performing data transmission on the Link in the activated state according to the mapping relation indicated by the parameter; and if the power saving mode enabling message does not contain the parameter TID2Link mapping for MLPS mode, performing data transmission on the Link in the activated state according to the mapping relation between the service before entering the power saving mode and the Link or by using a default mapping relation.
If the AP MLD1 does not agree with the mapping relationship between the service and the Link indicated in the power saving mode enabling message, namely the power saving mode enabling response message contains a parameter TID2Link mapping for MLPS mode, the STA MLD1 sends the power saving mode enabling message to the AP MLD1 again, the message contains a parameter TID2Link mapping for MLPS mode, and the value of the parameter TID2Link mapping for MLPS mode in the message is the same as the value of the parameter TID2Link mapping for MLPS mode in the received power saving mode enabling response message; after receiving the new power saving mode enabling message, the AP MLD1 sends a power saving mode enabling response message indicating that the power saving mode is enabled to the STA MLD1; the STA MLD1 receives a power saving mode enabling response message for agreeing to enable the power saving mode, and performs data transmission on the Link in the active state according to the mapping relation indicated by the parameter TID2Link mapping for MLPS mode in the new power saving mode enabling message with the AP MLD1.
Optionally, if the power saving mode enable message includes a parameter Linkmaxidletime, the AP MLD1 deletes information of a corresponding logical terminal in the STA MLD1 if the data sent by the STA MLD1 is received on the link in the sleep state indicated in the power saving mode enable message or the link in the sleep state indicated in the power saving mode enable message is not woken up within the time indicated by the parameter.
Optionally, if the power saving mode enable message includes parameters D2A enabled and Wake up condition, and the value of the parameter D2A enabled is 1, the AP MLD1 may Wake up the dormant link and the STA MLD1 to transmit data according to the condition indicated by the parameter Wake up condition.
In some embodiments, the STA MLD1 may change the setting of the power saving mode according to actual services, for example, when the user browses a web page, the STA MLD1 enters the power saving mode, and then the user starts playing a game or watching high-definition video, the STA MLD1 needs to add an activated link, or replace an original low-speed link with a high-speed link, or simply exit the power saving mode to activate all links. Examples of activation methods are as follows:
s204, the STAMLD1 sends a power saving mode change message to the multilink access device APMLD1.
If the STA MLD1 activates all links, the power saving mode change message includes the following parameters:
MLPS mode enabled: whether the multilink power saving mode is enabled or not, the embodiment is set to 0, which indicates that the power saving mode is disabled, that is, all links are in the activated state;
link2TID mapping for normal mode (optional): if the mapping relation between the link and the service is not contained, the mapping relation before entering the power saving mode is expected to be used, or a default mapping relation is used; if yes, the new mapping relation is negotiated.
If STA MLD1 changes the active link set and part of links are still in the dormant state, the power saving mode change message contains the following parameters:
MLPS mode enabled: whether the multilink power saving mode is enabled, the present embodiment is set to 1, indicating that the power saving mode is enabled.

Optionally, the parameter Switch delay may further include a parameter A2DSwitchdelay for indicating a delay of a change from an active state to a sleep state (turning off the transceiver), and a parameter D2Aswitchdelay for indicating a delay of a change from a sleep state to an active state (turning on the transceiver + timing synchronization), where the delay indicated by A2D Switch delay is shorter than the delay indicated by D2Aswitchdelay because the transceiver is turned off more quickly and timing synchronization is required after turning on the transceiver, and the delay is longer.
S205, the AP MLD1 receives the power saving mode change message sent by the STA MLD1, and sends a power saving mode change response message to the STA MLD1, where the message indicates whether to approve changing the power saving mode. Illustratively, the power saving mode change response message includes the following parameters:
MLPS mode enabled: whether the multilink power saving mode is enabled, if set to 1, indicates that the power saving mode is enabled; set to 0 indicates that the power saving mode is disabled. If the value of the parameter MLPS mode enabled contained in the power saving mode change message is 0, setting the parameter in the response message to be 0, indicating that the power saving mode is deactivated, namely indicating that the power saving mode is allowed to be changed; if the value of the parameter MLPS mode enabled included in the power saving mode change message is 1, the parameter in the response message is set to 1, which indicates that the power saving mode is enabled, i.e. indicates that the power saving mode is allowed to be changed. In other embodiments, instead of including the parameter, a Status parameter Status may be included, such as the parameter Status is set to 1 to indicate that the power saving mode is allowed to be changed, and set to 0 to indicate that the power saving mode is not allowed to be changed.
Link2TID mapping for MLPS mode (optional): if the power saving mode change message contains the parameter and the AP MLD1 agrees with the mapping relation, the response message may not contain the parameter; if the parameter is contained in the power saving mode change message, the AP MLD1 does not agree with the mapping relation, and the parameter is contained in the response message and is set as the mapping relation suggested by the AP MLD1; if the power saving mode change message does not contain the parameter, and the AP MLD1 wants to change the previous mapping relation or does not want to use the default mapping relation, the response message contains the parameter and is set as the mapping relation suggested by the AP MLD1; if the parameter is not included in the power saving mode change message, the AP MLD1 agrees to use the previous mapping relationship or agrees to use the default mapping relationship, and the parameter may not be included in the response message.
And S206, the STA MLD1 and the AP MLD1 perform data transmission on the link in the activated state indicated in the power saving mode change message according to the determined mapping relation between the service and the link in the changed power saving mode.
If the power saving mode change response message indicates that the power saving mode is not agreed to be changed, the STA MLD1 does not change the power saving mode, otherwise, the STA MLD1 and the AP MLD1 can transmit data according to the following modes:
and if the AP MLD1 agrees with the mapping relation between the service indicated in the power saving mode change message and the link, the STA MLD1 and the AP MLD1 perform data transmission on the link in the activated state indicated in the power saving mode change message according to the mapping relation between the service indicated in the power saving mode change message and the link.

If the AP MLD1 does not agree with the mapping relationship between the service and the Link indicated in the power saving mode change message, that is, the power saving mode change response message contains a parameter TID2Link mapping for MLPS mode, the STA MLD1 can send the power saving mode change message to the AP MLD1 again, the message contains a parameter TID2Link mapping for MLPS mode, and the value of the parameter TID2Link mapping for MLPS mode in the message is the same as the value of the parameter TID2Link mapping for MLPS mode in the received power saving mode change response message; after receiving the new power saving mode change message, the AP MLD1 sends a power saving mode change response message indicating that the power saving mode is allowed to be changed to the STA MLD1; the STA MLD1 receives the power saving mode change response message which agrees to change the power saving mode, and performs data transmission on the Link in the activated state according to the mapping relation indicated by the parameter TID2Link mapping for MLPS mode in the new power saving mode change message with the AP MLD1. Alternatively, the STA MLD1 may also terminate changing the power saving mode, i.e., using the previous power saving mode.
In some embodiments, before step S201, the STAMLD1 and the APMLD1 may determine the service type mapped on each link through a service-to-link mapping negotiation process, the STAMLD1 selects a default mapping relationship, or all services are mapped to part of links, the STA MLD1 selects a link in an active state from the links to which all services are mapped (only the links to which part of services are mapped are in a dormant state), and a bit corresponding to the selected link in the parameter enablingbitmap is set to 1, in this scenario, the message sent by the STA MLD1 to the AP MLD1 may not include the parameter TID2LinkmappingforMLPSmode, and the TID2 linkmapfapmode in the response message sent by the AP MLD1 is set as follows: if the AP MLD1 wants to change the previous mapping relation, the response message contains the parameter and is set as the suggested mapping relation; the AP MLD1 agrees to use the previous mapping relationship and the response message may not contain the parameter.
