The method according to claim 1, wherein the emergency enhanced packet attaching process is initiated by the established wireless resource connection, including:

And sending an attach request message whose attachment type is emergency enhanced packet attachment to the LTE network side; receiving an attach accept message sent by the LTE network side;

An attach complete message is sent to the LTE network side.

The method according to claim 2, wherein, before receiving the attach accept message sent by the LTE network side, the method further includes: performing, by the terminal, an authentication process with the LTE network side.

The method according to claim 3, wherein the terminal performs authentication processing with the network side, including:

Sending, by the LTE network, an authentication request to the terminal;

After receiving the authentication request, the terminal sends an authentication response to the LTE network side; the LTE network sends a security mode command to the terminal;

After receiving the security mode command, the terminal sends a security mode complete message to the LTE network side.

The method according to any one of claims 1 to 4, wherein establishing a dedicated data bearer with the LTE network side comprises:

Sending activating a dedicated bearer request message to a server on the LTE network side;

And receiving an activation dedicated bearer completion message sent by the server, and establishing a dedicated data bearer of the emergency call service with the LTE network side.

6. An apparatus for implementing an emergency call service of a terminal without a subscriber identity module SIM card, comprising: a first establishing module, configured to establish a radio resource connection between the terminal and the LTE network side; and an attaching module, configured to initiate an emergency enhanced packet attaching process by using the established radio resource connection;

The second establishing module is configured to establish a dedicated data bearer with the LTE network side after the emergency enhanced packet attaching process is completed, and perform an emergency call service by using the dedicated data bearer. The apparatus according to claim 6, further comprising: an authentication module configured to perform an authentication process with the LTE network side. A method for testing an emergency service capability of a terminal, including:

When the terminal without the subscriber identity module SIM card initiates an emergency call service, the system simulator detects a link request message sent by the terminal, and if the link request message is detected, the system simulator sends the message to the terminal. Wireless resource link setup message;

The system simulator detects an attach request message sent by the terminal, and when detecting the attach request message, the system simulator sends an attach accept message to the terminal;

The system simulator detects an attach complete message sent by the terminal, and if the attach complete message is detected, sends a dedicated data bearer request message to the terminal, and establishes a dedicated data bearer for the emergency call service with the terminal. . The method according to claim 8, wherein, after establishing a dedicated data bearer of the emergency call service with the terminal, the method further includes: the terminal implementing an emergency call service by using the dedicated data bearer;

After the emergency call service is completed, the method further includes:

Sending, by the terminal, a request message for deactivating the dedicated data bearer to the system simulator, where the system simulator responds to the request message for deactivating the dedicated data bearer, deactivating the dedicated data bearer, releasing and a radio resource link of the terminal;

The system simulator waits until a predetermined timer expires;

The system simulator detects whether a tracking area update request message sent by the terminal is received. The method according to claim 8 or 9, wherein the system simulator is used to simulate implementing an LTE network

11. A test device for emergency service capability of a terminal, comprising:

The first detecting module is configured to detect, when the terminal without the subscriber identity module SIM card initiates an emergency call service, the link request message sent by the terminal;

a first sending module, configured to send a radio resource link setup message to the terminal when the first detecting module detects the link request message;

a second detecting module, configured to detect an attach request message sent by the terminal, where the second sending module is configured to send an attach accept message to the terminal when the attach request message is detected;

a third detecting module, configured to detect an attach complete message sent by the terminal, where the third sending module is configured to send a dedicated data bearer request message to the terminal, where the terminal completes the message Establish a dedicated data bearer for emergency call services.

12. The device according to claim 11, further comprising:

Deactivating a module, configured to respond to the request message sent by the terminal after the completion of the emergency call service to activate the dedicated data bearer, to activate the dedicated data bearer, and release a radio resource link with the terminal;

The fourth detecting module is configured to detect whether the tracking area update request message sent by the terminal is received after the predetermined timer of the terminal expires.
