Embodiment 1

[0105] Embodiment 1: In the HRPD network, it can be divided into downlink data processing and uplink data processing.

[0106] Among them, the downlink data is a data packet from the PDSN to the PCF through the A10 interface, then from the PCF to the AN through the A8, and finally sent by the AN to the AT through the air interface.

[0107] When the downlink data arrives at the PDSN, the PDSN judges whether the length of the received data packet is less than the maximum length of the GRE payload (that is, the length of the remaining payload of the GRE to be sent), and if so, the PDSN sends these small data packets according to Figure 8 or Figure 9 The format is encapsulated in a GRE packet, and the GRE grouping attribute is set according to Figure 6 or Figure 7, which means that the GRE packet includes multiple data packets. If the attribute in Figure 7 is used, it also needs to be set in the GRE grouping attribute The number of data packets included in the GRE packet is final...

Embodiment 2

[0114] Embodiment 2: In an evolved network, it can be divided into downlink data processing and uplink data processing.

[0115] The downlink data is from the NMA to the CAP, and then the CAP sends the data packet to the AT through the air interface.

[0116] When the downlink data arrives at the NMA, the NMA judges whether the length of the received data packet is less than the maximum length of the GRE payload. If it is less, the NMA encapsulates these small data packets in a GRE packet according to the format shown in Figure 8 or Figure 9. And set the GRE packet attribute according to Figure 6 or Figure 7, indicating that the GRE packet includes multiple data packets, and set the number of packets included in the GRE packet in the GRE packet attribute, and finally through the interface between NMA and CAP forwarded to the CAP.

[0117] When the CAP receives the GRE packet, the CAP performs GRE decapsulation to determine whether the GRE packet attribute has a multi-packet i...

Abstract

The invention discloses a method for transmission of multiple data packet in mobile communications, which includes the following steps: on the side of a sending device, whether the length of the data packet to be transmitted is shorter than the segment payload length of generic routing encapsulation messages to be transmitted is determined: if the length of the data packet to be transmitted is shorter than the segment payload length of generic routing encapsulation messages to be sent, the data packets are encapsulated inside the generic routing encapsulation messages according to the preset encapsulation format, and a multiple packets mark is arranged; then the generic routing encapsulation messages are sent to a receiving device; while on the side of the receiving device, whether the messages have the mark of multiple packets is determined; if the messages bear the mark of multiple packets, the multiple data packets are resolved according to the preset encapsulation format. The invention also provides a system of multiple data packet transmission in mobile communications. The invention encapsulates a plurality of small data packets inside a generic routing encapsulation messages packet and then conducts transmission among various network nodes, so as to improve the network resource utilization rate and efficiency, save input of operators in network and decrease the operation cost of operators.

Description

technical field [0001] The present invention relates to the technical field of mobile communication data transmission, in particular to a method, system and equipment for transmitting multiple data packets in mobile communication. Background technique [0002] The existing CDMA (Code Division Multiple Access, Code Division Multiple Access) 2000 system, including CDMA 1x and HRPD (High Rate Packet Data, high-speed packet data) system, can provide a data rate of 153.6kbps, and can carry out VOD (Video On Demand) , video on demand), online games, high-speed data download and other packet data services. [0003] The existing CDMA2000 network packet domain structure is shown in FIG. 1 . In the figure, the solid line is the transmission path for carrying data, and the dotted line is the transmission path for signaling. MS (Mobile Station, mobile station) / AT (AccessTerminal, access terminal) is within the coverage of AN (Access Network, access network equipment) / PCF (Packet Contro...
