The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only partial embodiments of of the present invention, rather than all embodiments.
The embodiment of the invention provides a data Transmission method, which is applied to a Multi-Path Transmission Control Protocol (MPTCP) agent, and in combination with an application scenario shown in fig. 1, a User Equipment (UE) accesses a server through a packet data network gateway (PGW) agent and the Multi-Path Transmission Control Protocol (MPTCP) agent, the UE establishes a connection with a PGW after accessing a mobile network, the PGW device may include a TCP agent or both of the MPTCP agent and the MPTCP agent.
The data transmission method provided by the invention relates to two types of IP addresses, and the embodiment of the invention only takes IP addresses of two types, namely an IPv4 address and an IPv6 address as an example for explanation. This is of course not representative of the case where the present invention is applicable only to IPv4 addresses and IPv6 addresses.
The UE acquires two different types of IP addresses, including IPv4 addresses and IPv6 addresses, and establishes an MPTCP connection with the MPTCP proxy by using the two IP addresses.
The MPTCP connection between the MPTCP proxy and the server is different from the MPTCP connection between the MPTCP proxy and the UE in that the MPTCP connection established by the MPTCP proxy and the UE includes a Subflow (full name: Subflow) established by an IPv4 address and a Subflow established by an IPv6 address, while the MPTCP connection established by the MPTCP proxy and the server includes only subflows established by of an IPv4 address or an IPv6 address.
In the embodiment of the invention, th and second IP addresses are used for describing two different types of IP addresses acquired by UE respectively, wherein of the th and second IP addresses is an IPv4 address, and is an IPv6 address, the IP address of a server is an IPv4 address or an IPv6 address, and the th IP address, the IP address of the server is an IPv4 address and the second IP address is an IPv6 address are taken as examples for explanation.
Examples
An embodiment of the present invention provides data transmission methods, which are applied to an MPTCP proxy, and as shown in fig. 2, the method includes the following steps:
201. and receiving an access request message sent by User Equipment (UE).
The UE sends an access request message to the PGW to request for accessing the server, wherein the access request message comprises the IP address of the server and the th IP address of the UE, and the th IP address and the IP address of the server are the same type of IP addresses, namely, the IP addresses are all IPv4 addresses.
The PGW forwards the access request message to the MPTCP proxy or sends only the IP address of the server and the th IP address to the MPTCP proxy in order for the MPTCP proxy to establish a connection with the server and the UE, respectively.
202. And establishing connection with the server according to the IP address of the server.
The connection is established between the MPTCP proxy and the server, which includes the following two cases.
In case , the server does not support MPTCP, and the MPTCP proxy establishes a TCP connection with the server using the access IP address according to the IP address of the server, wherein the access IP address is the same type of IP address as the server address, i.e., an IPv4 address.
The access IP address can be th IP address of the UE, that is, after the MPTCP agent receives the access request message sent by the UE, the MPTCP agent establishes a TCP connection with the server by using the th IP address carried in the access request message.
Of course, the access IP address may also be another IPv4 address, for example, the access IP address is an IP address previously configured for the MPTCP proxy.
In the second case, the server supports MPTCP, and the MPTCP proxy establishes an MPTCP connection with the server according to the IP address of the server, so as to improve the data throughput between the MPTCP proxy and the server.
The MPTCP connection between the MPTCP proxy and the server can comprise at least subflows, wherein subflows correspond to IP address pairs, IP address pairs comprise IP addresses of the MPTCP proxy and IP addresses of the server, wherein the IP address of the MPTCP proxy refers to the IP address used when the MPTCP proxy and the server establish the subflows, and the IP address of the server refers to the IP address used when the server and the MPTCP proxy establish the subflows.
Optionally, the number of IP addresses of the server is 1, i.e. the IP address of the server only includes the IP address of the server included in the access request message, in this case, the MPTCP proxy establishes a subflow with the server using at least access IP addresses, wherein the access IP address is the same type of IP address as the IP address of the server, when the number of access IP addresses is 1, the access IP address may be the th IP address, when the number of access IP addresses is greater than 1, the access IP address may further include an IP address previously configured for the MPTCP proxy, as shown in table , the IP address of the subflow corresponds to the IP address pair, the IP address of the MPTCP proxy may be the th IP address, or the access IP address, the IP addresses of the server are all the same, and the IP address of the server included in the access request message is represented by IP address a in table .
TABLE
Optionally, the number of IP addresses of the server is greater than 1, and after the MPTCP proxy establishes th subflow with the server by using th IP address according to the IP address of the server included in the access request message, the server sends other IP addresses to the MPTCP proxy through the subflow.
Watch two
optionally, when the number of the IP addresses of the server is greater than 1 and an application scenario in which an access IP address is not preconfigured for the MPTCP proxy, the IP address of the MPTCP proxy may include only IP addresses, which is the th IP address, and the MPTCP proxy may still establish a plurality of sub-streams with the server, and in the IP address pairs corresponding to different sub-streams, the IP addresses of the MPTCP proxy are all th IP addresses, and the IP addresses of the server are different in each part.
203. And establishing a second connection with the UE according to the th IP address.
Combining table three, the process of establishing subflow and second subflow for the MPTCP proxy and the UE is described as follows:
watch III
The UE supports the dual-stack address, the IP address of the UE comprises th IP address and second IP address, the th IP address and the second IP address are different types of IP addresses, in the embodiment, the th IP address is an IPv4 address, the second IP address is an IPv6 address, the IP address of the server can be an IPv4 address or an IPv6 address, and the description is given by taking the case that the IP address of the server is an IPv4 address as an example.
After receiving the access request message, the MPTCP proxy establishes a th subflow with the UE by using the IP address of the server according to the th IP address of the UE, as shown in the third table, the IP address of the UE end corresponding to the th subflow is the th IP address, and the IP address of the MPTCP proxy is the IP address of the server.
Combining table three, the IP address of the UE end corresponding to the second subflow is the second IP address, and the IP address of the MPTCP proxy end is the proxy IP address, where the proxy IP address is an IP address configured for the MPTCP proxy in advance, and the proxy IP address and the second IP address are the same type of IP address, that is, an IPv6 address.
The establishment of the second sub-stream may be done in two ways, th way the MPTCP proxy sends a proxy IP address to the UE via th sub-stream, the UE establishes the second sub-stream with the MPTCP proxy based on the proxy IP address, further way the UE sends a second IP address to the MPTCP proxy via th sub-stream, the MPTCP proxy establishes the second sub-stream with the UE based on the second IP address.
In , the UE sets MP _ CAPABLE ID in TCP message sent to MPTCP proxy through subflow, and inquires whether the second MPTCP subflow can be established from MPTCP proxy.
And after receiving the proxy IP address, the UE sends the TCP message with the MP _ JOIN identification bit to the proxy IP address by using the second IP address to request to establish the second sub-stream. The MPTCP agent returns an ACK message of MP _ JOIN to the UE, and the second flow is established.
In the second mode, after the UE receives the ACK message of MP _ able returned by the MPTCP proxy, the UE sends the second IP address to the MPTCP proxy through ADD _ ADDR option.
After receiving the second IP address, the MPTCP proxy sends a TCP message with the MP _ JOIN identification bit to the second IP address by using the proxy IP address to request to establish a second sub-stream. And the UE returns the ACK message of the MP _ JOIN to the MPTCP agent, and the establishment of the second flow is completed.
204. The th connection is associated with the second connection.
After the th connection is associated with the second connection, the MPTCP proxy forwards a message received from the UE through the th connection to the server through the second connection, and forwards the message received from the server through the second connection to the UE through the th connection, that is, the UE can access the server through the MPTCP proxy, in the prior art, if the server only supports an IPv4 address, the UE can only access the server through an IPv4 address, and if the server only supports an IPv6 address, the UE can only access the server through an IPv6 address.
205. And deleting of the th sub-stream and the second sub-stream according to the traffic data volume of the UE.
Step 205 is an optional step.
The data transmission rate between the UE and the server is affected by the th connection and the second connection, and the MPTCP proxy can dynamically adjust the number of sub-streams included in each of the th connection and the second connection according to the traffic data volume of the UE, so as to adjust the data transmission rate between the UE and the server.
The method specifically comprises the steps of deleting of a sub-flow and a second sub-flow when the traffic data volume is smaller than a preset threshold value, and reestablishing the deleted sub-flow when the traffic data volume exceeds a second preset threshold value, wherein the second preset threshold value is larger than or equal to a preset threshold value.
Similarly, when the MPTCP proxy establishes an MPTCP connection with the server, the number of subflows may also be dynamically adjusted to adapt the respective data transmission rates of the th connection and the second connection.
According to the data transmission method provided by the embodiment of the invention, the MPTCP proxy establishes a second connection with the UE by receiving the access request message sent by the UE, establishes th connection with the server and establishes association between the second connection and th connection to complete message forwarding between the UE and the server, wherein the second connection is the MPTCP connection and comprises th sub-stream established by the UE and the MPTCP proxy by using th IP address and second sub-stream established by the UE and the MPTCP proxy by using the second IP address.
