Embodiment 1

[0043] Embodiment 1 of the present invention provides a method for transmitting IP data packets. An AP device (or through an IP gateway) is directly connected to an IP network through an IP interface, and transmits an IP data packet with a UE through an air interface (that is, the AP device transmits an IP data packet through an air interface to The IP data packet is sent to the UE, and the UE sends the IP data packet to the AP device through the air interface); in order to ensure the QoS required by the IP data packet on the air interface, such as Figure 5A As shown, for the processing flow of the AP device side, the method includes the following steps:

[0044] In step 501A, the AP device obtains the IP data packet that needs to be sent to the UE; wherein, the AP device can receive the IP data packet that needs to be sent to the UE from the IP network.

[0045]In step 502A, the AP device uses the type information of the IP data packet to determine a DRB (Data Radio Bearer, ...

Embodiment 2

[0100] Based on the same inventive concept as the above method, an access point AP device is also provided in the embodiment of the present invention, such as Figure 6 As shown, the AP equipment includes:

[0101]An obtaining module 11, configured to obtain an IP data packet that needs to be sent to the user equipment UE;

[0102] A determining module 12, configured to determine the data radio bearer DRB corresponding to the IP data packet by using the type information of the IP data packet;

[0103] A sending module 13, configured to send the IP data packet to the UE through the DRB.

[0104] The determination module 12 is specifically configured to query the DRB identification corresponding to the type information of the IP data packet through the correspondence between the pre-maintained type information and the DRB identification, and determine the IP data packet through the DRB identification. The DRB corresponding to the package.

[0105] When the determining module ...

Embodiment 3

[0114] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a user equipment UE, such as Figure 7 As shown, the user equipment includes:

[0115] Obtaining module 21, for obtaining the IP packet that needs to be sent to the access point AP device;

[0116] A determination module 22, configured to determine the data radio bearer DRB corresponding to the IP data packet by using the type information of the IP data packet;

[0117] A sending module 23, configured to send the IP data packet to the AP device through the DRB.

[0118] The determination module 22 is specifically configured to query the DRB identification corresponding to the type information of the IP data packet through the correspondence between the pre-maintained type information and the DRB identification, and determine the IP data packet through the DRB identification The DRB corresponding to the package.

[0119] When the determining module 22 maintain...

Abstract

The invention discloses a transmission method and equipment of an IP data packet. The transmission method comprises the following steps: AP (Access Point) equipment acquires an IP data packet which needs to be sent to UE (User Equipment); the AP equipment determines a data radio bearer (DRB) corresponding to the IP data packet by using the type information of the IP data packet; and the AP equipment sends the IP data packet to the UE through the DRB. According to the embodiment of the invention, under the condition that the AP equipment is locally accessed into an IP network or accessed into the IP network directly through an IP gateway, the QoS (Quality of Service) guarantee of the IP data packet in idle transmission is achieved on the basis of direct mapping between the type information and the data radio bearer.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and equipment for transmitting IP data packets. Background technique [0002] 1. IP (Internet Protocol, Internet Interconnection Protocol) business priority. [0003] In the IPv4 header, 8 bits are used to represent ToS (Type of Service, service type), such as figure 1 The schematic diagram of the IPv4 header shown and figure 2 The schematic diagram of the ToS field is shown; the first 3 bits in the ToS field indicate the IP priority, and the 8 values ​​shown in Table 1 can be defined; there are 4 bits of TOS and 1 bit unused in the ToS field; 4 bits of TOS represent: the minimum hour Delay D, maximum throughput T, maximum reliability R and minimum cost C. [0004] Table 1 [0005] [0006] Such as image 3 As shown, it is a schematic diagram of the header of IPv6. IPv6 has two fields related to QoS (Quality of Service, quality of service), namely TC (Traf...
