It means that the UE can transmit data through a wireless access network device (for example, a base station) and a core network and a service server.

In a 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 being used by the UE, the radio access network device may send indication information that does not allow service optimization, or may not perform an indication. The embodiment of the present invention does not limit the implementation of the related art.

Specifically, the mobility management entity (MME), the serving gateway (S-GW), or the packet gateway (P-GW) in the core network sends the policy and charging rule function (PCRF) to the Policy and Charging Rules Function (PCRF). A policy request, where the UE identifier and the obtained service information are carried, and the PCRF determines whether to allow the service currently being performed for the service to be optimized according to the pre-stored control policy, and returns the allowed service to the MME, the S-GW or the P-GW. Optimizing or disallowing the optimized policy response, the MME, S-GW or P-GW returns indication information allowing the service optimization or not allowing the service optimization to the radio access network device according to the policy response returned by the PCRF.

As another implementation manner of the embodiment of the present invention, the core network device may also initiate, under the trigger of the radio access network device, whether to allow the UE to optimize the service currently used by the UE.

Based on this, the information transmission method implemented by the core network side may further include the following steps: receiving a service optimization permission request sent by the wireless access network device, and carrying the service optimization permission request in the received service optimization permission request The UE is currently using the service information of the service, The core network determines, according to the obtained service information and the pre-stored service control policy, the radio access network device to perform service optimization on the service currently being used by the UE. Specifically, the MME, the S-GW, or the P-GW in the core network sends a policy request to the PCRF, where the UE identifier and the obtained service information are carried, and the PCRF determines, according to the pre-stored control policy, whether the service is currently being allowed for the service. The performed service is optimized, and the policy response that allows for service optimization or optimization is not returned to the MME, S-GW or P-GW, and the MME, S-GW or P-GW responds to the radio access according to the policy response returned by the PCRF. The network device returns indications that allow for service optimization or for which service optimization is not allowed.

Specifically, if the PCRF returns a policy that allows for service optimization, the MME, the S-GW, or the P-GW returns indication information that allows for service optimization to the radio access network device, and if the PCRF returns a policy that does not allow service optimization, The MME, the S-GW, or the P-GW returns indication information that is not allowed to perform service optimization to the radio access network device.

In the above process, if the PCRF returns a new charging policy to the MME, the S-GW, or the P-GW, the MME, the S-GW, or the P-GW also needs to update the charging policy for the current service used by the UE.

The optimization of the service currently being performed by the UE by the radio access network device includes two aspects of optimization, and the other is that the wireless optimization information is sent to the service server through the core network, so that the service server can be compared with the UE according to the wireless optimization information. The data transmission is optimized, and the other is local service optimization, that is, when the radio access network device side determines that the service currently being performed by the UE is a local service, the service data packet is no longer sent to the service server through the core network. It is forwarded directly by the wireless access network device to the locally deployed server. The two implementations are described separately below.

Embodiment 1 The radio access network device sends wireless optimization information to the service server for a service currently being used by the UE.

In this implementation manner, in step S11, it may be determined that the wireless access network device is allowed to be targeted. The service currently being used by the UE sends wireless optimization information to the service server. Correspondingly, if the radio network device triggers the core network device to perform step S11, the service optimization permission request sent by the receiving radio access network device may be a user plane that is sent by the receiving radio access network device and carries the wireless optimization information. Data message.

In some embodiments, the radio access network device may send the user plane data message to the core network device after receiving the service optimization request sent by the UE. In actual application, the UE may send a service optimization request to the radio access network device when detecting that the preset trigger condition is met, where the trigger condition may include at least one of the following conditions:

(1) When the UE initiates the initial connection, if the application server is a TCP server, the UE may send a service optimization request to the radio access network device during the TCP slow start phase, that is, the UE moves to the radio access network during the three-way handshake with the TCP. The device sends a service optimization request. If the application server is a video server, the UE may send a service optimization request to the wireless access network device during an initial connection with the video server.

(2) The UE detects a decrease in data transmission performance. For example, the UE detects that the number of times the duplicate acknowledgement packet (ACK) is received exceeds a preset threshold.

(3) The local service buffer of the UE is lower than a preset threshold. For example, the UE detects that the video being played locally is paused.

(4) The UE detects that the service quality indicator is lower than the preset quality indicator. For example, the UE detects that the quality parameter of the video quality being played by the local area is lower than the preset quality parameter value, or does not satisfy the preset quality parameter value, and the like. , the embodiments of the present invention are not listed one by one.

For example, in the fourth generation (4G) mobile communication system, the user plane data packet carrying the wireless optimization information may include a GTP-U packet, where the wireless optimization information may be encapsulated in the extension header of the GTP-U packet. That is, the wireless access network device may use the extended 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 Encapsulate the obtained wireless optimization information into The data payload is sent to the service server. For example, after receiving the GTP-U packet, the core network device obtains the wireless optimization information to be sent by parsing the GTP-U packet, and encapsulates the obtained GTP-U packet into a data payload (transport). Business server. If the core network device determines that the wireless access network device is not allowed to send the wireless optimization information, the wireless access network device may directly transmit the data packet sent by the UE to the service server.

Embodiment 2: The radio access network device performs local caching or local route optimization processing on the service currently being used by the UE.

In this implementation manner, step S11 may be performed to determine that the radio access network device is allowed to perform local service routing or local caching service offloading for the service currently being used by the UE.

Correspondingly, if the radio network device triggers the core network device to perform step S11, the service optimization permission request sent by the receiving radio access network device may be a local service sent by the receiving radio access network device for the service currently used by the UE. The routing request or the local cache service offloading request may carry the UE identifier and the service information that the UE is currently using the service, and if the core network device determines that the local service optimization process is allowed, return the indication for allowing the service optimization to the radio access network device. Information, otherwise, returns indication information that does not allow for service optimization to the radio access network device. The radio access network device sends the received service data packet to the local service server or the local cache server after receiving the service data packet sent by the UE according to the received indication information. It is no longer sent to the core network device for processing.

In order to better understand the embodiments of the present invention, the implementation of the present invention will be described below in conjunction with the various embodiments.

(1) When the UE initiates the initial connection, if the application server is a TCP server, the UE may send a service optimization request to the radio access network device during the TCP slow start phase, that is, the UE moves to the radio access network during the three-way handshake with the TCP. The device sends a service optimization request; if the application The server is a video server, and the UE may send a service optimization request to the radio access network device during the initial connection with the video server.

S53. The MME/S-GW/P-GW sends a policy request to the PCRF.

Here, the policy request sent by the MME/S-GW/P-GW to the PCRF carries the UE identifier and the service information that the UE is currently using the service.

S54. The PCRF determines, according to the obtained service information and the pre-stored service control policy, the radio access network device to perform local routing or local cache optimization processing for the UE currently using the service.

If yes, the policy is sent to the MME/S-GW/P-GW to allow local routing or local cache optimization processing for the UE currently using the service, and if not, to the MME/S-GW/P-GW. The policy of not performing local routing or local cache optimization processing for the UE currently using the service is not allowed.

S56. The MME/S-GW/P-GW sends, to the radio access network device, indication information whether to allow local routing or local cache optimization processing for the UE currently using the service.

In this step, the MME/S-GW/P-GW sends corresponding indication information according to the policy request response returned by the PCRF. Specifically, if the PCRF returns a policy response that allows local routing or local cache optimization processing for the UE currently using traffic, the MME/S-GW/P-GW sends a permission to the radio access network device (which may be referred to as RAN) for The UE is currently using the service to perform local routing or local cache optimization processing indication information. If the PCRF returns a policy response that does not allow local routing or local cache optimization processing for the UE currently using the service, the MME/S-GW/P-GW The indication to the radio access network device that local routing or local caching optimization processing is not allowed for the UE currently using the service is sent.

It should be noted that if the MME/S-GW/P-GW sends the radio access network device indication information that does not allow local routing or local cache optimization processing for the UE currently using the service, the radio access network device and the MME /S-GW/P-GW performs data packet transmission according to the prior art, that is, the data packet sent by the MME/S-GW/P-GW to the radio access network device is directly transmitted to the service server, and the present invention is implemented.
