Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
Fig. 1 sends the structural representation of the method first embodiment of data for the present invention to user terminal.As shown in figure 1,
The method for sending data to user terminal in the present embodiment specifically includes following job step：
The downlink data message that step 101, the reception server are sent.
In this step, the downlink data message that the reception server is sent, the purpose terminal of the downlink data message is use
Family terminal by LTE terminal, it is necessary to be forwarded to user terminal.Wherein, network side includes core net EPC, packet data gateway
（Packet Gate Way, PGW）The equipment such as network element；LTE terminal includes the equipment such as CPE or DTU；User terminal includes user
Computer, mobile phone, camera and various application terminals for using etc..The PGW network elements of network side receive server downlink data report
After text, the species of the IP address in detection downlink data message, the species of IP address includes the IP address and LTE of user terminal
The IP address of terminal.When the species of the IP address in downlink data message is the IP address of user terminal, into step 102.
Step 102, when downlink data message includes the IP address of user terminal, inquiry and user are whole in the routing table
The IP address of the corresponding LTE terminal of IP address at end.
In this step, when downlink data message includes the IP address of user terminal, inquiry is with using in the routing table
The IP address of the corresponding LTE terminal of IP address of family terminal.In the present embodiment, it is by the PGW network elements of network side that user is whole
The I P addresses at end and the IP address information configuration of LTE terminal into routing table, wherein, the IP address of user terminal is purpose IP
Address, the IP address of LTE terminal is next-hop ip address.
To avoid impacting existing routing configuration pattern, the IP address and LTE of the user terminal in the present embodiment
The routing table entry of the IP address of terminal is configured to default configuration entry, and route entry type is set to default fields, with convenient
PGW network elements are retrieved to IP address.After the downlink data message that server is sent reaches PGW network elements, according to core net EPC
The species of IP address in the downlink data message of configuration, PGW network elements carry out a routing table lookup first, pass through user terminal
IP address obtains the IP address of LTE terminal, subsequently into step 103.
Step 103, downlink data message is sent to by LTE terminal according to the IP address of LTE terminal, to pass through LTE terminal
Downlink data message is forwarded to user terminal.
In this step, after the IP address that LTE terminal is obtained by user terminal IP address, according to the IP of LTE terminal
Address carries out downlink business flow template（DownLink Traffic Flow Template, DL-TFT）Information matches, and retrieve
Go out the tunnel information of corresponding network transmission downlink data message, may then pass through general data transfer platform (General
Data Transfer Platform, GTP) downlink data message is packaged, will be descending with the IP address according to LTE terminal
Data message is sent to corresponding LTE terminal, and then LTE terminal sends downlink data message according to the IP address of user terminal
To corresponding user terminal.
In the present embodiment, when downlink data message includes the IP address of user terminal, in the routing table inquiry with
The IP address of the corresponding LTE terminal of IP address of user terminal, LTE terminal is sent to by downlink data message, with whole by LTE
Downlink data message is forwarded to user terminal by end, realizes the routing table configured according to network side, with completing IP to LTE terminal
Location is matched with the logic of the IP address of user terminal, enables the server to the quick user for directly accessing LTE terminal connection
Terminal, improves the efficiency of network communicating system.
Fig. 2 sends the structural representation of the method second embodiment of data for the present invention to user terminal.As shown in Fig. 2
The method for sending data to user terminal in the present embodiment specifically includes following job step：
Step 201, the logic in the routing table between the IP address of configuration user terminal and the IP address of LTE terminal are closed
System.

The downlink data message that step 202, the reception server are sent.
In this step, needed in the downlink data message that the reception server is sent, the downlink data message whole by LTE
End is forwarded to user terminal.After receiving downlink data message, into step 203.
The species of step 203, the IP address detected in downlink data message.
The IP address in downlink data message is parsed, the species of the IP address in downlink data message, IP is then detected
The species of address includes the IP address of user terminal and the IP address of LTE terminal.When the IP address in downlink data message is use
During the IP address of family terminal, into step 204；When IP address in downlink data message is the IP address of LTE terminal, enter
Step 206.
Step 204, when downlink data message includes the IP address of user terminal, inquiry and user are whole in the routing table
The IP address of the corresponding LTE terminal of IP address at end.
In this step, when downlink data message includes the IP address of user terminal, inquiry is with using in the routing table
The IP address of the corresponding LTE terminal of IP address of family terminal.In actual applications, if the data message that server is sent is reached
After PGW network elements, the species of the IP address in core net EPC configurating downlink data messages, PGW network elements carry out a routing table
Search, the IP address of LTE terminal is obtained by user terminal IP address, subsequently into step 205.
Step 205, downlink business flow template DL-TFT is carried out according to the IP address of LTE terminal matched, by downlink data report
Text is sent to LTE terminal, so that downlink data message is forwarded into user terminal by LTE terminal.
In this step, after the IP address that LTE terminal is obtained by user terminal IP address, according to the IP of LTE terminal
Address carries out DL-TFT information matches, retrieves the tunnel information of corresponding network transmission, can be with general data transfer platform
(General Data Transfer Platform, GTP) is packaged to downlink data message, then according to LTE terminal
Downlink data message is sent to corresponding LTE terminal by IP address, LTE terminal further according to user terminal IP address by lower line number
Corresponding user terminal is sent to according to message.
When step 206, the IP address in downlink data message are the IP address of LTE terminal, downlink data message is sent out
The corresponding LTE terminal of IP address is sent to, downlink data message is sent to user terminal by LTE terminal.
In this step, when downlink data message includes the IP address of LTE terminal, downlink data message is sent to
LTE terminal, the five-tuple business information that LTE terminal includes according to downlink data message is matched.If five-tuple business
Information matches success, then transmit downlink data message by dedicated bearer tunnel, and LTE terminal is by the IP according to user terminal
Downlink data message is forwarded to user terminal by location；If the matching of five-tuple business information is unsuccessful, pass through dedicated bearer tunnel
Road transmits downlink data message, and that downlink data message is forwarded to user by the IP address according to user terminal by LTE terminal is whole
End.
