Fourthly, when the ultra-low power consumption information is obtained from the mtc application server, the following method may be used, as shown in step a5 in fig. 3: for example, the mobility management element sends a registration Request (Register Request) message to the machine type communication application server, and the machine type communication application server sends a registration Response (Register Response) message to the target mobility management element, where the subscription data Response message may include at least one of ultra-low power consumption information, ultra-low power consumption application characteristics, and ultra-low power consumption indication information. If there is no direct interface connection between the mobility management element and the machine type communication application server, the mobility management network element will slave at least one of the machine type communication application server, the ultra-low power application feature and the ultra-low power indication information through the core network gateway, for example, the core network gateway transmits a registration Request (Register Request) message to the machine type communication application server, the machine type communication application server transmits a registration Response (Register Response) message to the core network gateway, the registration Response message may carry at least one of the ultra-low power consumption information, the ultra-low power consumption application characteristic, and the ultra-low power consumption indication information, and the core network gateway may carry at least one of the ultra-low power consumption information, the ultra-low power consumption application characteristic, and the ultra-low power consumption indication information to the mobility management network element by generating a Session Response (Create Session Response) message.

After obtaining the ultra-low power consumption information of the ue from the above device, determining which ultra-low power consumption information is used as the ultra-low power consumption information used by the end-user device and the network side together may be determined by using the following determination rules, but the embodiment of the present invention is not limited thereto, and when the embodiment of the present invention is specifically implemented, the corresponding determination rules may be specifically set according to the requirements of the user, and the rules may include the following types, and specifically may include:

firstly, when acquiring ultra-low power consumption information and acquiring user equipment low power consumption indication/ultra-low power consumption application characteristic information, the acquired ultra-low power consumption information is used as the ultra-low power consumption information commonly used by the end user equipment and the network side.

Secondly, when at least two pieces of ultra-low power consumption information are obtained from the network element and the low power consumption indication/ultra-low power consumption application characteristic information of the user equipment is obtained, one piece of ultra-low power consumption information is selected from the at least two pieces of ultra-low power consumption information and is used as the ultra-low power consumption information commonly used by the end user equipment and the network side.

Thirdly, when one or at least two pieces of ultra-low power consumption information are obtained from the device but no low power consumption indication/ultra-low power consumption application characteristic information of the user equipment is available, when one piece of ultra-low power consumption information is obtained from the device, the obtained piece of ultra-low power consumption information can be used as the ultra-low power consumption information commonly used by the end user equipment and the network side; when acquiring at least two pieces of ultra-low power consumption information from the device, any one piece of ultra-low power consumption information of the at least two pieces of ultra-low power consumption information can be used as ultra-low power consumption information commonly used by the end-user device and the network side; alternatively, it may be determined that ultra-low power consumption is not supported, and the user equipment may be indicated not to support ultra-low power consumption.

Fourthly, when the ultra-low power consumption information is not obtained from the equipment, but the low power consumption indication information/ultra-low power consumption application characteristics of the user equipment are obtained, determining that the ultra-low power consumption is not supported, and indicating that the user equipment does not support the ultra-low power consumption; or, the ultra-low power consumption information may be obtained according to configuration information of a network element (e.g., a mobility management network element) where the network element is located, and the configured ultra-low power consumption information is used as the ultra-low power consumption information commonly used by the end user equipment and the network side.

After a network side (e.g., a mobility management network element) learns the ultra-low power consumption information of the ue, the learned ultra-low power consumption information needs to be sent to the ue, as shown in step a7 in fig. 3, the mobility management network element sends an Attach Accept (Attach Accept)/tracking area update Accept (TAU Accept)/routing area update Accept (RAU Accept) message to the ue, and the Attach Accept/tracking area update Accept/routing area Accept message carries the learned ultra-low power consumption information, so that the ue learns when the ue enters the ultra-low power consumption state according to the ultra-low power consumption information.

In addition, if the ultra-low power consumption information of the ue changes, the following method may be specifically adopted by the mobility management network element to acquire the changed ultra-low power consumption information, and refer to a flow B in fig. 3, which may specifically include: a mobile management network element receives a sending and inserting signing data message sent by a home subscriber server or a machine type communication application server, wherein the sending and inserting signing data message can contain at least one of changed ultra-low power consumption information, ultra-low power consumption application characteristics and ultra-low power consumption indication information; or the mobility management network element receives a tracking area update request/routing area update request message sent by the user equipment, wherein the message may include at least one of changed ultra-low power consumption information, ultra-low power consumption application characteristics and ultra-low power consumption indication information; or the configuration information of the network element (such as a mobility management network element) is changed, and at least one of the changed ultra-low power consumption information, the ultra-low power consumption application characteristic and the ultra-low power consumption indication information is obtained.

After acquiring at least one of the changed ultra-low power consumption information, the ultra-low power consumption application characteristic, and the ultra-low power consumption indication information, the mobility management network element needs to further determine the information, which is not limited in the embodiment of the present invention, and the following method may be specifically adopted to determine the information:

first, when the changed ultra-low power consumption information is obtained from the above device, but the ultra-low power consumption application characteristic/ultra-low power consumption indication information is not changed, the obtained changed ultra-low power consumption information may be used as the ultra-low power consumption information commonly used by the end user device and the network side.

Secondly, when the ultra-low power consumption application characteristic/ultra-low power consumption indication information is changed and the user equipment is informed of no longer having the ultra-low power consumption application characteristic/ultra-low power consumption indication, the user equipment can be informed that the user equipment does not support ultra-low power consumption, and in addition, the ultra-low power consumption information of the user equipment can be deleted.

Thirdly, when it is known that the ultra-low power application characteristic/ultra-low power indication information changes and it is known that the ue starts to possess the ultra-low power application characteristic/ultra-low power indication, it can be known that the ue supports ultra-low power consumption, and the ultra-low power information obtained from the above devices can be used as the ultra-low power information commonly used by the end-user device and the network side or the ultra-low power information commonly used by the end-user device and the network side can be known according to the configuration information of the network element (e.g., mobility management network element) where the ue is located.

When the ultra-low power consumption information of the ue changes, the obtained updated ultra-low power consumption information also needs to be sent to the ue, and in addition, if a network side (e.g., a mobility management network element) learns that the ue does not support ultra-low power consumption, an indication that the ue does not support ultra-low power consumption may also be notified to the ue through the message, as shown in B7 of fig. 3.

202. And the mobility management network element restricts sending downlink service to the user equipment, or the mobility management network element informs other equipment that the user equipment enters an ultra-low power consumption state, so that the other equipment restricts sending downlink service to the user equipment.

When the mobility management network element notifies other devices that the user equipment enters an ultra-low power consumption state, so that the other devices limit sending downlink services to the user equipment, the other devices may be, but are not limited to, a machine type communication application server or a core network gateway; for example, after the mtc application server or the core network gateway receives the notification message, the mtc application server or the core network gateway restricts downlink traffic from being sent to the ue.

The notification message may include indication information that the ue is in an ultra-low power consumption state or enters the ultra-low power consumption state, and the other device may determine that the ue is in the ultra-low power consumption state according to the indication information. For example, the notification message (e.g., the ue status notification message) may include a ue status information element (State Indicator), where the information element indicates a status of the ue, for example, if the information element value is "Sleep", the status of the ue is identified as an ultra-low power consumption status, the other device receives the ue status notification message, and according to the obtained "Sleep" indication, it may be known that the ue status is currently in the ultra-low power consumption status.

If the mobility management network element is not directly connected with the machine type communication application server through an interface, the mobility management network element can inform the machine type communication application server that the user equipment is currently in the ultra-low power consumption state through a core network gateway. For example, the mobility management network element sends a Modify Bearer Request (Modify Bearer Request) message to the core network gateway, where the message includes a "Sleep" indication, and then the core network gateway sends a user equipment State Notification (UE State Notification) message to the machine type communication application server, where the message includes the "Sleep" indication, and the machine type communication application server receives the user equipment State Notification message including the "Sleep" indication, and learns that the user equipment is in the ultra-low power consumption State.

The method for limiting downlink service transmission to the user equipment may include: not sending downlink service, and sending the downlink service after the user equipment is awakened from the ultra-low power consumption state; or, sending a downlink service to a downlink network element, where the downlink service message includes delay indication information indicating that the downlink network element delays sending the downlink service, and the delay indication information includes time for delaying sending the downlink service; or, sending a notification message containing the indication information of stopping sending the downlink service to a sender of the downlink service; or, sending a notification message containing delay indication information of the delayed downlink service to a sender of the downlink service, wherein the delay indication information comprises time for delaying the downlink service; or, the downlink data in the received downlink service and/or the downlink signaling related to the downlink data are discarded, where the downlink signaling related to the downlink data may be, but is not limited to, a downlink data notification message, and the like.

For the embodiment of the present invention, the restricting, by the mobility management network element or the other device, the sending of the downlink service to the user equipment may specifically be:

first, the mobility management network element or the other device receives the downlink service, does not send the downlink service, and sends the received downlink service to the user equipment when learning that the user equipment is awakened from an ultra-low power consumption state.

Second, the mobility management element sends a paging message to a radio access network element, where the paging message may include delay indication information indicating that the downlink radio access network element delays sending the paging message, where the delay indication information includes a delay time for delaying sending the paging message, so that after the radio access network element receives the paging message, and after the access network element delays the delay time, the radio access network element sends the paging message to the ue, where the delay time is equal to a time interval (ultra-low power consumption duration timer timeout time — ultra-low power consumption duration timer started time) required for waking up the ue from an ultra-low power consumption state, where the time interval is calculated by the mobility management element; or, the other device (e.g., a machine type communication application server or a core network gateway) sends a downlink service to a downlink network element (e.g., a core network gateway or a mobility management network element), where the downlink service message may include delay indication information indicating that the downlink network element delays sending the downlink service, where the delay indication information includes delay time for delaying sending the downlink service, so that after the downlink network element receives the downlink service message, the downlink network element delays the delay time and then sends the downlink service to the user equipment, where the delay time is equal to a time interval (ultra-low power consumption duration timer timeout time — ultra-low power consumption duration timer started time) required for waking up the distance from the ultra-low power consumption state by the user equipment, which is calculated by the other device.

Thirdly, the mobility management network element or the other device (e.g., a core network gateway) sends a corresponding downlink data or signaling response message to the downlink service sender, where the response message indicates that the downlink service sender stops sending the downlink service, and in addition, the mobility management network element or the other device may notify the downlink service sender to send the cached downlink data/signaling after learning that the user equipment is awakened from the ultra-low power consumption state. The downlink service sender may be a core network gateway or a machine type communication application server, and the notification message may include a sending indication cell that explicitly indicates the core network gateway or the machine type communication application server to issue the cache data/signaling, or the notification message may include an indication that the user equipment has been awakened, and implicitly indicates the core network gateway or the machine type communication application server to issue the cache data/signaling.

Fourthly, the mobility management element or the other device (e.g., a core network gateway) sends a corresponding downlink service response message to the downlink service sender, where the response message may include delay indication information indicating that the downlink service sender delays the downlink service, where the delay indication information includes delay time for delaying sending the downlink service, where the delay time is equal to a time interval (ultra-low power consumption duration timer timeout time — ultra-low power consumption duration timer started time) that is calculated by the mobility management element and required for waking up the ue from the ultra-low power consumption state, and the downlink service sender may be the core network gateway or a machine type communication application server.

Fifth, the mobility management network element or the other device discards downlink data in the received downlink service and/or downlink signaling related to the downlink data, where the downlink signaling related to the downlink data may be, but is not limited to, a downlink data notification message, and the like. However, the mobility management element and the other device may only process other downlink services, where the other downlink services may include a message related to a network triggering the user equipment to initiate a service, or may include a remote device configuration message, or may include an update ultra-low power consumption information message, and the like.

203. After limiting the downlink service to be sent to the user equipment, the mobility management network element learns whether the user equipment is awakened from the ultra-low power consumption state; if it is determined that the ue wakes up from the ultra-low power consumption state, performing step 204; if it is determined that the ue is not awake from the ultra low power state, step 203 is executed by the inheriting.

Wherein, the step of the mobility management network element knowing whether the user equipment is awakened from the ultra-low power consumption state specifically comprises: the ultra-low power consumption information obtained by the mobility management network element further comprises the timeout time of an ultra-low power consumption duration timer, and the user equipment is determined to be awakened from the ultra-low power consumption state according to the timeout of the ultra-low power consumption duration timer.

Wherein the determining that the user equipment is awakened from the ultra-low power consumption state according to the timeout of the ultra-low power consumption duration timer may specifically include: when the user equipment enters an ultra-low power consumption state, starting an ultra-low power consumption continuous timer; and judging whether the ultra-low power consumption continuous timer is overtime according to whether the running time of the ultra-low power consumption continuous timer exceeds the overtime value of the ultra-low power consumption continuous timer, and if so, determining that the user equipment is awakened from an ultra-low power consumption state.

204. The mobility management network element sends the downlink service limited to be sent to the user equipment, or the mobility management network element informs other equipment that the user equipment is awakened from an ultra-low power consumption state; and the other equipment sends the downlink service limited to be sent to the user equipment.

When the mobility management network element informs the other equipment that the user equipment is awakened from an ultra-low power consumption state; when the other device sends the downlink service limited to be sent to the user equipment, the other device may be, but is not limited to, a machine type communication application server or a core network gateway; for example, after the mtc application server or the core network gateway receives the notification message, the mtc application server or the core network gateway sends the downlink service restricted from being sent to the ue.

The notification message contains indication information that the user equipment is in a non-ultra-low power consumption state or awakens from the ultra-low power consumption state, so that other equipment knows that the user equipment is awakened from the ultra-low power consumption state. For example, the notification message (e.g., the ue status notification message) may include a ue status information element (State Indicator), where the information element indicates a status of the ue, e.g., if the information element value is "Wake", the status of the ue is identified as waking from the ultra-low power consumption State, the other device receives the ue status notification message, and according to the obtained "Wake" indication, it may be known that the ue status is currently in the ultra-low power consumption State.

If the mobility management network element is not directly connected with the machine type communication application server through an interface, the mobility management network element can wake up the user equipment from an ultra-low power consumption state to inform the machine type communication application server through a core network gateway. For example, the mobility management network element sends a Modify Bearer Request (Modify Bearer Request) message to the core network gateway, where the message includes a "Wake" indication, and then the core network gateway sends a UE State Notification (UE State Notification) message to the mtc application server, where the message includes the "Wake" indication, and the mtc application server receives the UE State Notification message including the "Wake" indication, and learns that the UE is in the ultra-low power consumption State.

In this embodiment, the notification message containing the indication information that the ue is in the ultra-low power consumption state or enters the ultra-low power consumption state and the notification message containing the indication information that the ue is in the non-ultra-low power consumption state or wakes up from the ultra-low power consumption state may be the same type of notification message, and the notification messages are distinguished and notified respectively by including different indications, or may be two types of notification messages of different types, which is not limited in this embodiment.

Wherein, the sending, by the mobility management network element or the other device, the downlink service restricted from being sent to the user equipment may specifically include: when the mobility management element or the other device restricts the downlink traffic from being sent to the user equipment by using the first method in step 202, the mobility management element sends the restricted downlink traffic to the user equipment; when the mobility management element or the other device restricts the downlink service from being sent to the user equipment by using the second method in step 202, the downlink element sends the restricted downlink service to the user equipment; when the mobility management network element or the other device restricts the downlink service from being sent to the user equipment by using the third and fourth methods in step 202, the downlink service sender sends the restricted downlink service to the user equipment.

205. And the mobility management network element or other equipment directly sends the downlink service to the user equipment.

In the embodiment of the invention, a mobility management network element acquires the ultra-low power consumption information of user equipment, and determines that the user equipment enters an ultra-low power consumption state according to the ultra-low power consumption information; the mobility management network element determines that the user equipment is in an ultra-low power consumption state and limits sending of downlink services to the user equipment, or the mobility management network element determines that the user equipment is in the ultra-low power consumption state and sends a notification message to notify other equipment that the user equipment is awakened from the ultra-low power consumption state; enabling the other equipment to send the downlink service limited to be sent to the user equipment; compared with the prior art, the method and the device have the advantages that the ultra-low power consumption state is introduced to meet the requirement of ultra-low power consumption of the user equipment, the downlink service is limited to be sent to the user equipment when the user equipment is in the ultra-low power consumption state, interaction of signaling required when the downlink service is sent is avoided, and network resources are saved.

In addition, in the embodiment of the present invention, in the process of limiting the downlink service to be sent to the user equipment, whether the user equipment is awakened from the ultra-low power consumption state is further known, and if it is determined that the user equipment is awakened from the ultra-low power consumption state, the downlink service limited to be sent is sent to the user equipment, so that accurate sending of the downlink service is ensured.

Wherein, the determining, by the ue, that the ue enters the ultra-low power consumption state according to the ultra-low power consumption preparation timer being overtime may specifically include: when user equipment enters an idle state or is awakened from an ultra-low power consumption state, the user equipment starts an ultra-low power consumption preparation timer; judging whether the ultra-low power consumption preparation timer is overtime or not according to whether the running time of the ultra-low power consumption preparation timer exceeds the overtime of the ultra-low power consumption preparation timer contained in the ultra-low power consumption information or not; and if the time is out, determining that the user equipment enters an ultra-low power consumption state.
