Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, and a medium for processing a service data packet.
Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
The LTE (Long Time Evolution) radio interface protocol stack includes a user plane protocol stack and a control plane protocol stack. Wherein the user plane protocol stack comprises: a physical layer (PHY), a Media Access Control (MAC) layer, a Radio Link Control (RLC) layer, a Media Access Control (MAC) layer, and a Packet Data Convergence Protocol (PDCP) layer. The Control plane protocol stack further includes a Radio Resource Control (RRC) layer and a non-access stratum layer based on the above architecture.
In the LTE wireless communication system, data packets of both the user plane and the control plane require encryption and decryption processes. Most (about 59.16%) of the latency in the L2 layer results from the ciphering and deciphering process of the PDCP layer. For some services with low time delay and large data volume, the data volume is very large, if all the data packets are encrypted and decrypted, the data transmission time delay is seriously increased, and the user experience is reduced.

Detailed Description
In order to reduce the transmission delay of a data packet, embodiments of the present invention provide a method, an apparatus, and a medium for processing a service data packet.
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.
In the embodiment of the invention, aiming at the problem that the existing wireless side carries out encryption and decryption processing on all the received data packets without distinction so as to increase data transmission time delay, when the data packets are sent by the service server, the data processing identification is added in the data packets according to the importance of the data carried in the data packets, so that a data packet receiver can carry out differentiated encryption and decryption operation on the received data packets according to the data processing identification carried in the data packets, thereby improving the data packet processing speed and reducing the data packet transmission time delay.
The service data packet processing method provided by the embodiment of the invention is particularly suitable for processing the service data packet with low time delay and large data volume, and can be used for processing the service data packet with harsh time delay requirement, so that the transmission time delay of the data packet can be greatly reduced.
According to the embodiment of the invention, the encryption and decryption functions of the PDCP layer are required to be changed from fixed to configurable, according to the configuration of the encryption and decryption functions of the PDCP layer, during specific implementation, the encryption and decryption functions of the PDCP layer can be configured to an encryption and decryption mode which is required to be carried out and an encryption and decryption mode which is not required to be carried out, and during specific implementation, the encryption and decryption functions of the PDCP layer can be configured through a core network through RRC (radio resource control) signaling. If the PDCP layer does not receive the encryption and decryption function configuration indication, the PDCP layer encryption and decryption processing is carried out on the received data packet according to the prior art.
As shown in fig. 1, which is a schematic view of an implementation flow of a service data packet processing method provided in an embodiment of the present invention, the method may include the following steps:
and S11, receiving the service data packet sent by the service server.
The service data packet carries a data packet processing identifier, and the data packet processing identifier is used for indicating whether the service data packet needs to be encrypted and decrypted by a PDCP layer.
In specific implementation, when the service server sends a data packet, a data packet processing identifier may be added to the data packet according to the importance of data transmitted in the data packet. For example, if the importance of the transmitted frame is higher, the VR server may add a packet processing identifier that needs to perform PDCP layer encryption/decryption, and if the transmitted frame is unimportant, the VR server may add a packet processing identifier that does not need to perform encryption/decryption.
Preferably, when implemented, the packet handling identifier may include a packet weight value. For convenience of description, the packet processing identifier is taken as an example of a packet weight value.
S12, the PDCP layer encryption and decryption processing is carried out on the received data packet according to the data packet processing identification.
In this step, after receiving the data packet, the wireless side may determine whether to perform PDCP layer encryption/decryption processing on the received data packet according to the data packet processing identifier carried in the data packet.
In specific implementation, the wireless side may perform differentiated encryption and decryption processing on the received data packet according to any one of the following manners:
the first embodiment,
In the first embodiment, the Service Data Adaptive Protocol (SDAP) module on the wireless side may map the Service Data Adaptive Protocol (SDAP) module to different DRB (Data Radio bearer) types according to a Data packet processing identifier carried in a Service Data packet, where the different DRB types correspond to different PDCP processing modes, where the PDCP processing modes include an encryption/decryption required mode and an encryption/decryption unnecessary mode.
In the method, by mapping the SDAP to DRBs of different types according to the packet processing identifier carried by the service packet, a CN (Core Network) is required to sense the packet weight value in the application packet, information such as a flow ID (flow identifier), a packet frame number, a packet weight value and the like carried by a GTP-U (general packet radio service) Protocol is submitted to the SDAP, and the SDAP maps the flow to the DRBs of different types according to the information carried by the SDAP for transmission. For example, the PDCP corresponding to the DRB1 does not encrypt/decrypt the mode; PDCP encryption/decryption mode corresponding to the DRB 2.
Based on this, before executing step S12, the method for processing the service data packet according to the embodiment of the present invention further includes the steps of: according to the data packet weight value carried in the service data packet, mapping the service data packet to a data radio bearer DRB type corresponding to the data packet weight value, where different DRB types correspond to different PDCP processing modes, where the PDCP processing modes include an encryption/decryption required mode and an encryption/decryption unnecessary mode, and thus, in step S12, it may be determined whether PDCP layer encryption/decryption processing needs to be performed on the service data packet according to the PDCP processing mode corresponding to the DRB that transmits the service data packet.
The second embodiment,
In the second embodiment, the service server needs to negotiate a packet weight threshold with a PDCP module on the wireless side in advance, so that the PDCP module performs PDCP layer encryption and decryption on a received packet by identifying a packet weight value in the received packet and comparing the packet weight value with the packet weight threshold, if the packet weight value is greater than the packet weight threshold; and if the weight value of the data packet is not greater than the weight threshold value of the data packet, the PDCP layer encryption and decryption processing is not carried out on the received data packet.
Based on this, in the service data packet processing method provided in the embodiment of the present invention, before executing step S11, the method may further include the following steps: and receiving a data packet weight threshold value sent by the service server. Thus, in step S12, according to the packet weight value carried by the service packet, if the packet weight value exceeds the packet weight threshold, the PDCP layer encryption and decryption processing may be performed on the service packet; and if the weight value of the data packet does not exceed the weight threshold value of the data packet, the PDCP layer encryption and decryption processing is not carried out on the service data packet. Preferably, the data packet weight threshold is sent by the core network through radio resource control RRC signaling.
For better understanding of the embodiments of the present invention, the following describes the implementation process of the present invention by taking VR service as an example.
As shown in fig. 2, which is a schematic diagram of a processing flow of a VR packet according to an embodiment of the present invention, the processing flow may include the following steps:
s21, the VR server determines the weight value of the data packet to be transmitted.
In this step, the VR server determines a weighted value of the data packet according to a frame number of a VR service data packet transmission frame.
And S22, the VR server adds the weight value in the data packet to be transmitted and then sends the data packet to the core network equipment.
In this step, the VR server sends the frame number and the weight value corresponding to the VR service data packet to the core network device.
S23, the core network device sends GTP-U message to the SDAP module of the wireless side.
In this step, the core network device encapsulates the frame number of each frame of the VR service, the weight value of each data packet in the frame, and the service flow identifier in the GTP-U packet, and sends the GTP-U packet to the SDAP module.
And S24, the SDAP module maps the data packet into different DRB types according to the weight value according to the received GTP-U message.
Wherein, different DRB types correspond to different PDCP configurations to carry out PDCP layer differentiated encryption and decryption.
As shown in fig. 3, which is a schematic diagram of a processing flow of a VR packet according to a second embodiment of the present invention, the processing flow may include the following steps:
and S31, the VR server sends the data packet weight threshold value to the core network equipment.
In this step, the VR server determines a data packet weight threshold, where the data packet weight threshold is used to indicate whether the PDCP needs to encrypt or decrypt the received VR data packet.
S32, the core network device configures the packet weight threshold value of the PDCP layer.
In this step, the core network device configures the packet weight threshold of the PDCP layer through RRC signaling according to the packet weight threshold sent by the VR server.
S33, the VR server adds a data packet weight value for the VR data packet to be transmitted.
In this step, the VR server determines a weight value corresponding to the VR packet according to the importance of the data frame transmitted in the packet to be transmitted. The packet weight value involved in the embodiment of the present invention may include two values, one of which is greater than the packet weight threshold value, and the other of which is not greater than the packet weight threshold value.
And S34, the VR data packet sends the VR data packet added with the weight value of the data packet to the core network equipment.
S35, the core network device sends the VR packet with the added packet weight value to the PDCP module of the wireless side.
S36, the PDCP module compares the data packet weight value in the VR data packet with the data packet weight threshold value, and determines whether the PDCP layer encryption and decryption processing needs to be carried out on the received data packet according to the comparison result.
Specifically, in this step, if the packet weight value exceeds the packet weight threshold, the PDCP layer encryption and decryption processing is performed on the VR packet; and if the weight value of the data packet does not exceed the weight threshold value of the data packet, the VR data packet is not subjected to PDCP layer encryption and decryption processing.
In the method, the device and the medium for processing the service data packet provided by the embodiment of the invention, the service server adds the data packet processing identifier in the service data packet, so that the receiver can selectively perform PDCP layer encryption and decryption processing on the data packet according to the data packet processing identifier added in the received data packet without performing PDCP layer encryption and decryption processing on all the data packets which are not identified, thereby improving the data packet processing speed and reducing the transmission delay of the data packet.
Based on the same inventive concept, embodiments of the present invention further provide a device and a medium for processing a service data packet, and because the principles of solving the problems of the device and the medium are similar to the method for processing a service data packet, the implementation of the device and the medium can refer to the implementation of the method, and repeated details are not repeated.
