Mode 1, satellite gateway are direct as the load of the short message of mobile communications network using the satellite short message received Short message format is encapsulated as, which is sent to short messaging gateway, and is indicated in the short message that short messaging gateway receives Carry satellite short message.

Specifically, satellite gateway is after ground satellite station or satellite server receive satellite short message, by what is received Satellite short message is directly encapsulated as short message format as the load of the short message of mobile communications network, i.e.,：In the encapsulation process, Satellite gateway does not parse the content of the satellite short message, is directly encapsulated as the short message format of mobile communications network, and The short message is sent to short messaging gateway.

Under which, satellite gateway can use to be taken in the short message that following either type instruction short messaging gateway receives With satellite short message：

Mode A1, satellite gateway are direct as the load of the short message of mobile communications network using the satellite short message received When being encapsulated as short message format, the first configured information is carried in the message of the carrying short message sent to short messaging gateway, To indicate to carry satellite short message in short message that short messaging gateway receives；

In which, since satellite gateway sets first to refer in the message of the carrying short message sent to short messaging gateway Show information, to indicate to carry satellite short message in short message that short messaging gateway receives, therefore, there is no need to extra signaling Expense.

Mode B1, satellite gateway are received with to indicate short messaging gateway by sending indication signaling to short messaging gateway Satellite short message is carried in short message.

Under which, satellite gateway can be defended receiving ICBM SHF satellite terminal by what ground satellite station or satellite server were sent Before star short message, indication signaling first is sent to short messaging gateway, the satellite is come to indicate that short messaging gateway is subsequently received Satellite short message is carried in the short message that gateway is sent, i.e. satellite gateway need to only send once instruction to short messaging gateway and believe Order；Satellite gateway can also pass through ground satellite station or the short report of satellite of satellite server transmission receiving ICBM SHF satellite terminal every time After text, before the short message for carrying the satellite short message is sent, indication signaling all is sent to short messaging gateway, it is short to indicate Satellite short message is carried in the short message that information gateway receives, i.e. satellite gateway carries satellite short message in each send Before short message, all an indication signaling is sent to intermediate node.

Based on aforesaid way 1, after short messaging gateway receives the short message of satellite gateway transmission, intermediate node（Including short Information gateway and core network control node）Can using be pre-configured with and for satellite communication RNTI scrambled by the way of to Mobile terminal in mobile communications network issues the short message sent from satellite gateway；Broadcast mode can also be used to movement Mobile terminal in communication network issues the short message sent from satellite gateway.Short-message sending under which kind of mode is specifically used, It can be pre-configured with to intermediate node.

Based on aforesaid way 1, if intermediate node uses the RNTI for being pre-configured with and being used for satellite communication to being defended for carrying Short-message sending under mobile terminal of the mode that the down control channel of star short message is scrambled into mobile communications network, then defend Before short message is sent to short messaging gateway by StarNet pass, this method further includes：

Satellite gateway obtains the granting region of the satellite short message, determines the short report of the satellite according to preconfigured information The addressing information for providing the core network control node in region of text, and addressing letter is carried in the message for carrying short message Breath.

For example, the satellite gateway in mobile communications network is configured with satellite gateway can send the region of satellite short message （That is the granting region of satellite short message）Information, then the satellite gateway granting can be determined according to the information in the granting region The addressing information of core network control node in region, further core network control node determined by acquisition.

Correspondingly, short messaging gateway receive satellite gateway transmission carry the message of the short message after, according to taking The addressing information carried in message with the short message, sends this to the corresponding core network control node of the addressing information and short disappears Breath, wherein, which does not parse the content of short message.

Based on aforesaid way 1, RNTI that is preconfigured and being used for satellite communication is used to for holding for intermediate node The mode that the down control channel of load satellite short message is scrambled issues satellite short message, and network side is in mobile communications network All mobile terminal fixed allocations with satellite short message receiving ability one are used for the RNTI of satellite communication, i.e., all to have One identical RNTI of mobile terminal fixed allocation of satellite short message receiving ability, each mobile terminal monitor downlink control letter Road, when detecting the preconfigured RNTI for satellite communication, in the shared channel scheduled in the down control channel It is upper to receive the short message sent from intermediate node, it is seen then that short message can be pre-configured with this and be used for satellite communication by all The mobile terminal of RNTI receives；Since in the embodiment of the present invention, network side only needs to be all there is satellite short message to receive One RNTI for being used for satellite communication of mobile terminal fixed allocation of ability, reduces network processes complexity, saves network Resource.

It should be noted that mobile terminal is received in the mechanism of short message at present, network side is interim for each mobile terminal One C-RNTI of distribution, i.e., each terminal one different C-RNTI of interim distribution, each terminal monitoring down control channel, When detecting the C-RNTI that network side distributes for itself, short disappear is received in the shared channel scheduled in the down control channel Breath, it is seen then that short message can only be received by the recipient of the short message；In existing short message reception mechanism, since network side is Each mobile terminal distributes a C-RNTI temporarily, and when sending short message, network side needs the recipient using the short message Corresponding C-RNTI is scrambled, and adds network processes complexity, and network side needs to preserve each mobile terminal and C- The mapping relations of RNTI, add the expense of Internet resources.
