For example, if the mobility management network element includes the IP address of the UE in the session management request message, the IP address of the UE may be regarded as the foregoing indication information. ), the gateway device stores the information of the UE.

2. The gateway device learns that the UE's application feature (MTC Feature) is a low mobility MTC Feature, and stores the UE information. The low mobility feature includes the UE does not move, the UE moves in a fixed area, or the UE is nomadic. ;

For example: If the application feature included in the session management request message by the mobility management network element is low mobility, the gateway device stores the information of the UE.

3. The gateway device stores the information of the UE according to the configured group identity of the UE. For example, the group identifier of the information that needs to be stored in the UE is configured on the gateway device, and if the gateway device receives the session management request message sent by the mobility management network element, the session management request message includes the identifier of the UE that belongs to or is included in the foregoing configuration. The group identifier, or the group identity request message in the foregoing session management request message is equal to the group identity of the above configuration, and the gateway device stores the information of the UE learned from the session management request message.

In this step, if the gateway device does not have the context information of the UE (for example, the bearer or the PDP context), if the gateway device receives the data information of the UE, and the gateway device learns the IP address of the UE according to the data information of the UE, the gateway device according to the foregoing The IP address of the UE queries the stored information to obtain the information of the UE, for example: the identifier of the UE, or the identifier of the UE and the information of the mobility management network element serving the UE, or the identifier of the UE and the location of the UE, or the identifier of the UE, or the service. The information of the UE's mobility management network element and the location of the UE.

The method for obtaining the information of the UE provided by the step, if the application server (MTC User or MTC Server) triggers the UE to initiate the connection establishment, the gateway device can learn the information of the UE from the stored information, thereby avoiding configuring a large amount of the gateway device. The information of the UE is avoided, and the information of the UE is configured in different network elements, thereby reducing the workload of operation and maintenance. In addition, if the gateway device learns at least one of the information of the mobility management network element serving the UE and the information about the location of the UE from the foregoing storage information, the gateway device does not need to learn the information of the UE from the subscription database, thereby avoiding the gateway device. Support for the Gc interface reduces the complexity of gateway device implementation. Step 103: Obtain information about a mobility management network element that serves the UE according to the learned information of the UE.

The gateway device needs to know the information about the mobility management network element of the serving UE before triggering the UE to initiate the connection establishment, which may be as follows:

A. Obtain information about the mobility management network element of the serving UE from the information of the UE.

B. The information about the mobility management network element of the serving UE is obtained according to the location information of the UE in the information of the UE.

Specifically, the gateway device can learn the information of the mobility management network element of the serving UE according to the relationship between the location information of the stored or configured UE and the information of the mobility management network element of the serving UE.

C. Query the subscription database according to the identifier of the UE (for example, IMSI) in the information of the UE, and obtain information about the mobility management network element of the serving UE.

For example, the gateway device sends a GPRS routing information (Send Routing Information for GPRS) message to the subscription database, where the message includes the identifier of the UE, and the subscription database returns information of the mobility management network element of the serving UE to the gateway device. Further, if the location information of the UE is stored in the subscription database, the subscription database returns the location information of the UE to the gateway device.

Step 104: Trigger the UE to initiate a connection establishment process by using the mobility management network element corresponding to the information of the mobility management network element serving the UE.

The gateway device initiates a connection initiation process by triggering the UE according to the information of the learned UE. For example, the gateway device may trigger the UE to initiate connection establishment by using the mobility management network element.

In this step, the gateway device learns the information of the mobility management network element of the serving UE, and sends an indication message to the corresponding mobile management network element to trigger the establishment of the connection, and the indication message includes the identifier of the UE that needs to initiate the connection establishment. among them,

And the identifier of the UE is included in the message.

Optionally, the foregoing indication message may further include location information of the UE, where the mobility management network element pages the UE within the range indicated by the location information of the UE.

After the mobile management network element receives the indication message, if the UE is in the idle state or the UE is in the disconnected state, the mobility management network element triggers the corresponding UE to establish a connection according to the identifier of the UE in the indication message. Specifically, the foregoing mobility management network element may initiate, according to the identifier of the UE in the indication message, a page that includes the identifier of the UE, to page the UE corresponding to the identifier of the UE included in the indication message; optionally, the foregoing paging The message may include indication information indicating that the UE initiates service establishment, for example: indication information indicating that the UE initiates a PDP context activation procedure.

The mobility management network element can page the UE within a specific range (for example, a cell, a routing area, a tracking area, or a tracking area identifier list) without paging the UE within the service range of the entire mobility management network element, thereby improving the The pertinence and efficiency of paging reduces the paging volume and reduces the probability of network congestion, thus ensuring the normal operation of the network. Specifically, the mobility management network element can learn the range of paging by the following methods:

1. The indication message sent by the gateway device includes the location information of the UE, and the mobility management network element pages the UE within the range indicated by the location information of the UE; 2. The mobility management network element initiates paging according to a customized paging rule;

For example, after the mobile management network element receives the indication message, the mobility management network element learns the identifier of the UE included in the indication message. If the UE corresponding to the identifier of the UE is in the connected state, the mobility management network element sends the NAS to the UE. a message to indicate that the UE initiates a connection establishment.

2. If the UE is in the connected state, the mobility management network element releases the connection of the UE (for example, a lu connection or an S1 connection), and after the connection of the UE is released, the mobility management network element may initiate a paging including the identifier of the UE. The UE corresponding to the identifier of the UE included in the indication message is paged. For example, after the mobile management network element receives the indication message, the mobility management network element learns the identifier of the UE included in the indication message. If the UE corresponding to the identifier of the UE is in the connected state, the mobility management network element translates the UE. Connect, initiate a page that includes the identifier of the UE, to page the UE corresponding to the identifier of the UE included in the indication message. For details, the method for the mobile management network element to initiate the paging including the identifier of the UE can be referred to the above description, and details are not described herein again.

Optionally, after receiving the foregoing indication message, the mobility management network element may further return an indication response message to the gateway device. Specifically, after receiving the indication message that is sent by the gateway device and including the identifier of the UE, the mobility management network element may respond and return an indication response message. Where, if the above refers If the message is a packet data message notification request message, the indication response message returned by the mobility management network element may be a packet data message response response (PDU Notification Response) message; if the indication message is a downlink data notification message, then the mobility management The indication response message returned by the network element may be a Downlink Date Notification Ack message.

After receiving the NAS message or the paging message that is sent by the mobility management network element, the UE initiates the connection establishment process, including:
