One specific embodiment of the present invention, as shown in fig. 8, takes the transmission of a micro-mail as an example, and includes:
when the user a sends the APP information to the user B, as in the process 801, the user a uses the local area network internal IP address allocated by the operator, that is, the message source address sent to the user B by the user a uses the mobile local area network internal IP address, and the destination of the message uses the external network IP address and the user tag allocated to the user B by the APP service provider.
When the message is sent to the Internet through the gateway of the operator, the source address and the port of the message are mapped to the external IP address and the port of the operator, so that the source address and the destination address of the message sent from the user A to the user B are converted into the external IP address.
After the data message is delivered to the APP server, the IP address of the user B is replaced by the external network IP address and the port which are distributed to the user B by the operator, the data message is continuously delivered to the user B, the data message is delivered to the operator gateway, the conversion between the destination address and the port and the internal address and the port of the local area network is completed, the data message is delivered to the user B, and the communication message is supported to complete the delivery from the user A to the user B. At EPC and APP server side, the data message will be mapped and converted by IP address.
If the invention is adopted, the first message sent by the user A to the user B carries the ECGI and intranet IP address information of the user A, the user B replies the first message of the user A and carries the ECGI and intranet IP address information of the user B, and the ECGI and intranet IP address information does not need to be sent again if the ECGI and intranet IP address information is not changed in the subsequent communication process.
and the app client stores the ECGI and intranet IP address information of the user, and updates the ECGI and intranet IP address information if the new ECGI and intranet IP address information of the friend is received.
The user A stores ECGI and intranet IP address information of the user B according to the app client, if the user A is in the same base station eNB with the user A, the message target side address directly adopts the intranet IP address of the user B, the flow is shown as a blue line in the figure, and the base station directly forwards data to a corresponding user when detecting that the IP address of the target address is the user of the base station at the eNB side. If the user a determines that the user B and the user B are not in the same base station or the message sent by using the address of the local area network of the opposite terminal does not receive the reply within 3 round trip times RTT, the user a uses a transmission data sending method, and the process flow 801 is followed. When the user B replies the confirmation message of the user A, if the ECGI or IP address information of the user B is changed since the last communication with the user A, the ACK message carries new ECGI and intranet IP address information of the user B, and the user A updates the ECGI and intranet IP address information of the user B which is stored locally after receiving the message.
In the process 802, the eNB establishes a C-RNTI _ GID and user IP address corresponding table by analyzing the IP data packet header. If the source address and the destination address of the message are both in the same eNB, the base station does not deliver the message to the EPC and directly forwards the message to the corresponding User in the base station.
If both communicating parties change the base station or change the IP address information, the app client updates the local ECGI and the intranet IP address information and simultaneously sends the updated ECGI and intranet IP address information to the communicating opposite terminal. After receiving the change message of the base station of the ECGI of the opposite end or the change message of the intranet IP address information, if the two communication parties are no longer located in the same base station, the sending method exits from the local area network, the process 803 is adopted, and the data packet which is not confirmed by the opposite end is converted into the traditional data sending method. If the ECGI is still in the same base station but the intranet IP address information is changed, the message which is not confirmed by the opposite terminal is retransmitted after the intranet IP address information is updated.
If 3 continuous messages are lost, the local area network mode is exited, and the data transmission mechanism of the flow 801 is adopted.
In a specific embodiment of the present invention, as shown in fig. 9, a charging method according to the present invention includes:
step 901: the user A and the user B adopt the method of the invention to communicate, because the data does not pass through a core network charging system, the eNB is required to count the data volume of the communication between the user A and the user B and record the data volume by using a performance indicator KPI.
Step 902: the base station reports the data volume of communication between the user A and the user B to the core network by one granularity every five minutes, and the core network completes charging statistics.
A specific embodiment of the present invention, as shown in fig. 10, introduces how to implement a coordinated communication process between different users, including:
the user A and the opposite-end user B of the communication are in the same local area network, and after the user A client detects the ECGI and the IP address information of the internal network of the opposite end, the direct communication can be carried out in a 1001 mode.
If the user C does not adopt the invention or adopts the invention, but finds that the user C communicating with the user C is positioned in a different base station, the 1002 mode is adopted for communication.
In an embodiment of the present invention, a computer-readable storage medium is further provided, which is used for storing the computing program provided in the foregoing embodiment, so as to complete the steps of the foregoing method. The computer readable storage medium can be Memory such as FRAM, ROM, PROM, EPROM, EEPROM, Flash Memory, magnetic surface Memory, optical disk, or CD-ROM; or various devices including one or any combination of the above memories, such as mobile phones, computers, smart appliances, servers, etc.
