In order to optimize the current service of the UE under the assistance of the wireless access network equipment and improve the reliability of data transmission, the embodiment of the invention provides an information transmission method, an information transmission device, an information transmission system and related equipment.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
As shown in fig. 1, an implementation flow diagram of a first information transmission method provided by the embodiment of the present invention is implemented on a core network side, and may include the following steps:
s11, when determining that the wireless access network equipment is allowed to perform service optimization on the service currently used by the UE, sending indication information for allowing the service optimization to the wireless access network equipment.
In a specific implementation, the core network device may determine that the radio access network device is allowed to perform service optimization on a service currently used by the UE when the UE and the service server are in a connected state, where the UE (user equipment) and the service server in a connected state according to the embodiment of the present invention means that the UE may transmit data through the radio access network device (e.g., a base station) and the core network and the service server.
In specific implementation, if the core network device determines that the radio access network device is not allowed to perform service optimization on the service currently used by the UE, the core network device may send indication information that the service optimization is not allowed to the radio access network device, or may perform the indication without performing the indication, which is performed according to the existing service flow, and this is not limited in the embodiment of the present invention. For convenience of description, the following description takes an example in which when the core network device determines that the radio access network device is not allowed to perform service optimization on a service currently used by the UE, the core network device sends indication information that the service optimization is not allowed to the radio access network device.
The process shown in fig. 1 is to actively initiate a judgment on whether to allow optimization of a service currently used by the UE for the core network, and preferably, the core network obtains service information of the service currently used by the UE by analyzing a data packet transmitted between the UE and the service server, and determines, according to the obtained service information and a pre-stored service control policy, to allow the wireless access network device to perform service optimization on the service currently used by the UE.
Based on this, before executing step S11, the following steps may be further included:
s11', analyzing the data packet transmitted between UE and service server, and obtaining the service information of the service currently used by UE.
In specific implementation, the core network device may analyze a data packet transmitted between the UE and the service server by using a DPI method, so as to obtain service information of a service currently used by the UE.
And the core network determines to allow the wireless access network equipment to carry out service optimization on the service currently used by the UE according to the obtained service information and a pre-stored service control strategy. Specifically, an MME (mobility management entity), an S-GW (serving gateway) or a P-GW (packet gateway) in a core network sends a Policy request to a PCRF (Policy and Charging Rules Function), where the Policy request carries a UE identifier and obtained service information, the PCRF determines whether to allow optimization for a current ongoing service of the service according to a pre-stored control Policy, and returns a Policy response that allows or disallows the optimization of the service to the MME, the S-GW, or the P-GW, and the MME, the S-GW, or the P-GW returns indication information that allows or disallows the optimization of the service to a radio access network device according to the Policy response returned by the PCRF.
And S11', determining to allow the wireless access network equipment to carry out service optimization on the service currently used by the UE according to the obtained service information and the pre-stored service control strategy.
As another implementation manner of the embodiment of the present invention, the core network device may also initiate a determination whether to allow optimization of a service currently used by the UE under the trigger of the radio access network device.
Based on this, the information transmission method implemented by the core network side, before performing step S11, may further include the following steps: and receiving a service optimization permission request sent by the wireless access network equipment, wherein the received service optimization permission request carries service information of a service currently used by the UE, and the core network determines to allow the wireless access network equipment to perform service optimization on the service currently used by the UE according to the obtained service information and a pre-stored service control strategy. Specifically, an MME (mobility management entity), an S-GW (serving gateway) or a P-GW (packet gateway) in a core network sends a policy request to a PCRF (policy and Charging Rules Function), where the policy request carries a UE identifier and obtained service information, the PCRF determines whether to allow optimization for a current ongoing service of the service according to a pre-stored control policy, and returns a policy response that allows or disallows the optimization of the service to the MME, the S-GW, or the P-GW, and the MME, the S-GW, or the P-GW returns indication information that allows or disallows the optimization of the service to a radio access network device according to the policy response returned by the PCRF.
Specifically, if the PCRF returns a policy allowing for service optimization, the MME, S-GW, or P-GW returns indication information allowing for service optimization to the wireless access network device, and if the PCRF returns a policy disallowing for service optimization, the MME, S-GW, or P-GW returns indication information disallowing for service optimization to the wireless access network device.
In the above process, if the PCRF returns a new policy such as charging to the MME, S-GW, or P-GW, the MME, S-GW, or P-GW needs to update the charging policy for the current service used by the UE.
The method comprises the following steps that a wireless access network device optimizes the current service of the UE in two aspects, one is to send wireless optimization information to a service server through a core network so that the service server can optimize data transmission between the wireless access network device and the UE according to the wireless optimization information, and the other is local service optimization, namely when the wireless access network device side judges that the current service of the UE is a local service, a service data packet is not sent to the service server through the core network any more, but the wireless access network device directly forwards the current service to a locally deployed server. These two embodiments are described below separately.
In a first embodiment, the radio access network device sends radio optimization information to the service server for a service currently used by the UE.
In this embodiment, in step S11, the radio optimization information may be sent to the service server for the service currently being used by the UE for the determination that the radio access network device is allowed to use. Accordingly, if the core network device is triggered to execute step S11 for the radio access network device, the service optimization permission request sent by the receiving radio access network device may be a user plane data packet carrying radio optimization information and sent by the receiving radio access network device.
Preferably, the radio access network device may send the user plane data packet to a core network device after receiving the service optimization request sent by the UE. Preferably, the UE may send a service optimization request to the radio access network device when detecting that a preset trigger condition is met, where the trigger condition may include at least one of the following conditions: (1) when the UE initiates initial connection, if the application server is a TCP server, the UE can send a service optimization request to the wireless access network equipment at a TCP slow start stage, namely the UE sends the service optimization request to the wireless access network equipment in a three-way handshake process with TCP; if the application server is a video server, the UE can send a service optimization request to the wireless access network equipment in the process of establishing initial connection with the video server; (2) the UE detects a degradation in data transmission performance. For example, the UE detects that the number of times a duplicate ACK (acknowledgement packet) is received exceeds a preset threshold. (3) The UE local service cache is lower than a preset threshold, for example, the UE detects that the video playing being played locally is stopped. (4) The UE detects that the service quality indicator is lower than the preset quality indicator, for example, the quality parameter of the video quality being played by the UE in the local area is lower than the preset quality parameter value, or does not satisfy the preset quality parameter value, and so on.
Taking 4G (fourth generation) mobile communication system as an example, the user plane data packet carrying the wireless optimization information may include a GTP-U packet (user plane general packet radio service tunneling protocol), where the wireless optimization information may be encapsulated in an extension header of the GTP-U packet. That is, the wireless access network device may utilize the extension header of the GTP-U packet sent to the core network device to carry the wireless optimization information, and if the core network device determines that the access network device is allowed to send the wireless optimization information, the wireless optimization information needs to be obtained, and the obtained wireless optimization information is encapsulated in the data load and sent to the service server. For example, after receiving a GTP-U packet, the core network device obtains wireless optimization information to be sent by parsing the GTP-U packet, and encapsulates the obtained GTP-U packet in a data load (payload) to transmit to the service server. And if the core network device determines that the wireless access network device is not allowed to send the wireless optimization information, the data packet sent by the wireless access network device for the current service used by the UE can be directly transmitted to the service server.
In the second embodiment, the radio access network device performs local caching or local route optimization processing on the service currently used by the UE.
In this embodiment, step S11 may be to determine to allow the radio access network device to perform local traffic routing or local cache traffic offloading on the traffic currently being used by the UE.
Correspondingly, if the core network device is triggered to execute step S11 for the radio access network device, the service optimization permission request sent by the receiving radio access network device may be a local service routing request or a local cache service offloading request sent by the receiving radio access network device for a service currently being used by the UE, where the local service routing request or the local cache service offloading request may carry a UE identifier and service information of the service currently being used by the UE, and if the core network device determines that local service optimization processing is allowed, the core network device returns indication information that service optimization is allowed to the radio access network device, otherwise, the core network device returns indication information that service optimization is not allowed to the radio access network device. And the wireless access network equipment receives the service data packet sent by the UE according to the received indication information and if the received indication information is the indication information allowing service optimization, sends the received service data packet to a local service server or a local cache server and does not send the service data packet to the core network equipment for processing.
For a better understanding of the embodiments of the present invention, the following description will be given with reference to various embodiments.

In this step, the PCRF determines whether to allow the wireless access network device to send the wireless optimization information to the service server according to a pre-stored control policy. If the wireless optimization information is allowed to be sent, a strategy for allowing the wireless optimization information to be sent is issued to the MME/S-GW/P-GW, and if the wireless optimization information is not allowed to be sent, a strategy for not allowing the wireless optimization information to be sent is issued to the MME/S-GW/P-GW.

And S27, the MME/S-GW/P-GW packages the wireless optimization information into the data load and sends the data load to the service server.
As shown in fig. 3a, which is a schematic diagram of a first implementation flow triggered by a radio access network device to optimize a service currently being used by a UE, the implementation flow may include the following steps:
s31, the radio access network device parses the data packet sent by the UE.
In this step, after the UE establishes signaling/data connection with the radio access network device, the radio access network device may parse a data packet sent by the UE. For example, the radio access network device performs DPI (deep packet inspection) or IP quintuple analysis on a data packet sent by the UE to obtain service information of a service being used by the UE, where the service information may be a service type or a service identifier, for example, the radio access network device analyzes the data packet sent by the UE to obtain a destination IP therein, and determines the service type or the service identifier of the service currently being performed by the UE according to a correspondence between a pre-stored IP address and the service type by using the obtained destination IP.

S32, the wireless access network device sends the business optimization permission request to MME/S-GW/P-GW.

In the process of establishing communication connection between the UE and the service server and transmitting data, the core network device analyzes a data packet transmitted between the UE and the service server, for example, a TDF (traffic detection function entity) performs DPI (deep packet inspection) or IP quintuple analysis on the data packet transmitted between the UE and the service server to obtain service information of a service being used by the UE, where the service information may be a service type, for example, the TDF analyzes the data packet to obtain a destination IP therein, and determines the service type of the service currently being used by the UE according to a correspondence between a pre-stored IP address and the service type by using the obtained destination IP.
It should be noted that step S41 is not an essential step in the embodiment of the present invention, and when the step S41 is implemented specifically, whether to implement step S41 may be determined according to actual needs.

In this step, the PCRF determines, according to a pre-stored control policy, whether to allow the radio access network device to perform local routing or local cache optimization processing for the service currently being used by the UE. If yes, issuing a strategy for allowing local routing or local cache optimization processing aiming at the service currently used by the UE to the MME/S-GW/P-GW, and if not, issuing a strategy for not allowing local routing or local cache optimization processing aiming at the service currently used by the UE to the MME/S-GW/P-GW.

For example, the UE detects that the number of times a duplicate ACK (acknowledgement packet) is received exceeds a preset threshold. (3) The UE local service cache is lower than a preset threshold, for example, the UE detects that the video playing being played locally is stopped.

And S53, the MME/S-GW/P-GW sends a policy request to the PCRF.
Specifically, the MME/S-GW/P-GW sends a policy request to the PCRF, where the policy request carries the UE identity and service information of the service currently being used by the UE.
And S54, the PCRF determines to allow the wireless access network equipment to carry out local routing or local cache optimization processing aiming at the service currently used by the UE according to the obtained service information and the pre-stored service control strategy.
In this step, the PCRF determines whether to allow local routing or local cache optimization for the service currently being used by the UE according to a pre-stored control policy. If the policy is not allowed, the policy which is not allowed to carry out the local routing or local cache optimization processing on the service currently used by the UE is issued to the MME/S-GW/P-GW.

It should be noted that, if the MME/S-GW/P-GW sends, to the radio access network device (RAN), indication information that local routing or local cache optimization processing is not allowed for a service currently used by the UE, data packet transmission is performed between the radio access network device and the MME/S-GW/P-GW according to the prior art, that is, a data packet sent by the MME/S-GW/P-GW to the radio access network device is directly passed through to the service server, which is not described in detail in the embodiment of the present invention.
