determining that a paging message for paging the narrowband terminal needs to be sent; and

sending a paging message comprising narrowband terminal information of the narrowband terminal to a base station, the narrowband terminal information indicating a radio capability of the narrowband terminal, and enabling the base station to transmit the paging message to the narrowband terminal in a control channel in accordance with the radio capability for the narrowband terminal to detect the paging message carried in the control channel sent by the base station;

wherein the narrowband terminal information comprises the radio capability of the narrowband terminal;

pre-acquiring the radio capability of the narrowband terminal;

storing a correspondence between a terminal identity (ID) of the narrowband terminal and the radio capability of the narrowband terminal; and

before sending the paging message, acquiring, according to the terminal ID of the narrowband terminal, the radio capability corresponding to the terminal ID from the stored correspondence, and writing the acquired radio capability into the paging message.

2. The method according to claim 1, wherein pre-acquiring the radio capability of the narrowband terminal comprises at least one of:

acquiring, from a non-access stratum (NAS) message transparently transmitted by the base station, the radio capability of the narrowband terminal borne in the NAS message,

wherein the NAS message is a message transparently transmitted by the base station when the narrowband terminal is performing attachment to a network or a tracking area update;

after it is determined, according to an international mobile subscriber identity (IMSI) or an international mobile equipment identity (IMEI) of the narrowband terminal, that the narrowband terminal is a narrowband terminal, acquiring the radio capability of the narrowband terminal from a network device storing the IMSI or the IMEI;

acquiring the radio capability of the narrowband terminal from a terminal capability information indication sent by the base station, wherein the radio capability of the narrowband terminal is a radio capability acquired by the base station from a message sent by the narrowband terminal;

or

acquiring the radio capability of the narrowband terminal from a radio capability notification message sent by the base station, wherein the radio capability of the narrowband terminal is a radio capability that is acquired by the base station according to an extended random access resource adopted by the narrowband terminal to access a network and corresponds to the extended random access resource.

3. The method according to claim 1, further comprising:

prestoring a correspondence between a service type of a service activated by the narrowband terminal and the radio capability of the narrowband terminal; and

before sending the narrowband terminal information, acquiring, according to a service type of a service triggering the paging message, the radio capability corresponding to the service type of the service triggering the paging message from the prestored stored correspondence, and writing the acquired radio capability into the paging message.

4. The method according to claim 1, wherein the narrowband terminal information comprises a narrowband terminal indication indicating the narrowband terminal whereby the base station transmits the paging message according to the radio capability of the narrowband terminal after acquiring the radio capability of the narrowband terminal according to the narrowband terminal indication.

5. The method according to claim 4, wherein sending the paging message comprises at least one of:

Sending the paging message with the narrowband terminal indication added in a new information field of the paging message to the base station;

sending the paging message to the base station through a dedicated mobility management entity (MME) of the narrowband terminal, wherein the paging message sent by the dedicated MME of the narrowband terminal indicates the narrowband terminal;

sending a generated paging message in a preset format to the base station, wherein the generated paging message in the preset format indicates the narrowband terminal;

or

sending a paging message comprising a terminal ID of the narrowband terminal to the base station, wherein the terminal ID indicates the narrowband terminal.

6. A network device, comprising:

a processor, configured to determine that a paging message for paging a narrowband terminal needs to be sent; and

a transmitter, configured to send a paging message comprising narrowband terminal information of the narrowband terminal to a base station after the processor determines that the paging message for paging the narrowband terminal needs to be sent, the narrowband terminal information indicating a radio capability of the narrowband terminal, and enabling the base station to transmit the paging message to the narrowband terminal in a control channel in accordance with the radio capability for the narrowband terminal to detect the paging message carried in the control channel sent by the base station;

wherein the narrowband terminal information comprises the radio capability of the narrowband terminal, whereby so the paging message is configured in the base station reads the radio capability of the narrowband terminal from the paging message and transmits the paging message according to the radio capability of the narrowband terminal;

wherein the processor is further configured to;

pre-acquire the radio capability of the narrowband terminal; and

store a correspondence between a terminal ID of the narrowband terminal and the radio capability of the narrowband terminal, the terminal ID and the radio capability acquired by a first acquiring unit.

7. The network device according to claim 6, the processor is further configured to:

acquire, according to the terminal ID of the narrowband terminal, the radio capability corresponding to the terminal ID from the correspondence stored by a first storing unit; and

write the radio capability into the paging message.

8. The network device according to claim 6, wherein the radio capability of the narrowband terminal is pre-acquired:

acquiring, from a NAS message transparently transmitted by the base station, the radio capability of the narrowband terminal borne in the NAS message, wherein the NAS message is a message transparently transmitted by the base station when the narrowband terminal is performing attachment to a network or a tracking area update;

or

after it is determined, according to an IMSI or an IMEI of the narrowband terminal, that the narrowband terminal is a narrowband terminal, acquiring the radio capability of the narrowband terminal from a network device storing the IMSI or the IMEI;

or

acquiring the radio capability of the narrowband terminal from a terminal capability information indication sent by the base station, wherein the radio capability of the narrowband terminal is a radio capability acquired by the base station from a message sent by the narrowband terminal;
