Embodiment Construction

[0056] In the technical solution of the present invention, after the UE sends the access preamble and receives the corresponding access instruction, it marks a PDU that is not allowed to be sent at the top of the local PDU sequence as permission to send, and checks whether the PDU sequence is There are still PDUs that are not allowed to be sent. If so, the access preamble is sent to the Node B again, without waiting for the UE to send the PDU that is allowed to be sent this time to the NodeB through the PRACH, and then send the access preamble to the Node B. When the UE needs to send multiple consecutive PDUs through the PRACH, the present invention partially overlaps the two random access procedures of two adjacent PDUs in parallel, thereby shortening the time used for sending all PDUs and improving the transmission rate of the PDUs sent to the Node through the PRACH. The processing efficiency of B sending uplink data.

Abstract

The invention discloses a method and a consumer device for sending out seriate and a plurality of PDUs to solve the problem of low efficiency brought by carrying out the random access procedure of sending out each PDU in order when UE needs to send out seriate and a plurality of PDUs through PRACH in the prior art. The method includes that after UE sends out the access fronting and receives corresponding access indication, one PDU which is not allowed to be sent out at the most anterior end in local PDU sequence is labeled to be allowed to be sent out and UE checks whether a PDU not allowed to be sent out exists in the PDU sequence. If so, then UE sends out access fronting to Node B again. The consumer device includes a memory module, an access fronting transmission module, an access indicating receiving module and a judging module. The invention has shortened time of sending out all PDU when sending out seriate and a plurality of PDU to Node B through PRACH and improved the processing efficiency of sending out forward data.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for sending a plurality of consecutive protocol data units and user equipment. Background technique [0002] In the CDMA (Code Division Multiple Addressing, Code Division Multiple Access) system, the uplink data sent by the UE (User Equipment, user equipment) can not only be transmitted in the uplink dedicated channel, but also in the RACH (Random Access Channel, random access channel ), the UE maps the RACH data to a PRACH (Physical Random Access Channel, Physical Random Access Channel) and sends it to the Node B (base station). [0003] When the UE needs to send uplink data on the PRACH, it needs to perform random access first, please refer to Figure 1, which is a flowchart of random access in the CDMA system, which mainly includes steps: [0004] Step S10, the UE sends an access preamble to the Node B; [0005] Step S11, after the Node B detects the acces...
