Random access message distinguishing method, network side equipment and mobile terminal

Abstract

The embodiment of the invention provides a random access message distinguishing method, network side equipment and a mobile terminal. The method comprises the following steps: receiving a first mediaaccess control layer protocol data unit sent by a mobile terminal through a physical layer uplink shared channel, wherein the first media access control layer protocol data unit carries a random access request message; and if it is judged that the first media access control layer protocol data unit carries the two-step random access type identifier, determining that the random access request message is the load of the Msg A in the two-step random access process. According to the method, the network side equipment and the mobile terminal provided by the embodiment of the invention, the networkside equipment judges whether the first media access control layer protocol data unit carries the identifier for distinguishing the random access type or not, so that the network side equipment can distinguish the random access request message according to the judgment result; and error processing and response are avoided, and the network access time delay of the mobile terminal is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for distinguishing random access messages, network side equipment and a mobile terminal. Background technique [0002] In the 5G network, in addition to the traditional 4-step random access process, in order to shorten the network access delay of the mobile terminal UE, a 2-step random access process is introduced. [0003] figure 1 is the signaling interaction diagram of the 4-step random access process in the prior art, such as figure 1 As shown, the steps of the 4-step random access process are as follows: [0004] 1. The UE triggers a 4-step random access process, and sends Msg 1 to the base station gNB through the Physical Random Access Channel (PRACH), where Msg1 carries a preamble, which corresponds to a preamble ID; [0005] 2. After the gNB successfully receives and decodes Msg 1, it calculates the Random Access-Radio Network Tempory Identity (...
