Abstract

An access procedure processing method, an apparatus, and a communications device are provided. The method includes: performing matching between N pieces of to-be-transmitted transmission data and a first condition; and based on a matching result, executing a first access procedure or a second access procedure. M pieces of transmission data are transmitted in the first access procedure, the N pieces of the transmission data are not transmitted in the second access procedure, and the M pieces of the transmission data are data matching the first condition in the N pieces of the transmission data. M and N are positive integers, and M is less than or equal to N. The first condition is a restriction condition for the data transmitted during the access procedure. The first condition includes: first bearer information corresponding to the transmission data or a first transmission mode matching configuration information.

First claim

The invention claimed is:

1 . A method for access procedure processing, comprising:
performing matching between N pieces of to-be-transmitted transmission data and a first condition; and when the N pieces of the transmission data satisfy the first condition, executing a first access procedure, wherein the N pieces of transmission data are transmitted in the first access procedure, and the first condition is a restriction condition for the data transmitted during the access procedure, wherein the first condition comprises: first bearer information corresponding to the transmission data or a first transmission mode matching configuration information, and the configuration information comprises second bearer information or a second transmission mode, wherein executing the first access procedure comprises sending, by a terminal, data to a network device directly through at least one of the following:
a Msg 3 in a 4-step random access procedure for initial access;
a Msg A in a 2-step random access procedure for initial access; or
a dedicated uplink resource configured by a network; or
wherein executing the first access procedure comprises sending, by the network device, data to the terminal directly through at least one of the following:
a Msg 4 in the 4-step random access procedure for initial access;
a Msg B in the 2-step random access procedure for initial access; or
a downlink feedback resource corresponding to the dedicated uplink resource configured by the network.

2 . The method according to claim 1 , wherein executing the first access procedure comprises:
when at least one piece of the N pieces of the transmission data satisfies the first condition, executing the first access procedure.

3 . The method according to claim 1 , further comprising:
when at least one piece of the N pieces of the transmission data does not satisfy the first condition, executing a second access procedure.

4 . The method according to claim 1 , wherein the second bearer information comprises at least one of the following: a bearer identity or a bearer type.

5 . The method according to claim 4 , wherein the bearer type comprises at least one of the following: a master cell group (MCG) data radio bearer (DRB), a secondary cell group (SCG) DRB, an MCG split DRB, or an SCG split DRB.

6 . The method according to claim 4 , wherein the bearer identity comprises at least one of the following: a DRB identity, a quality of service flow identity, a protocol data unit session identity, or a cell group identity.

7 . The method according to claim 1 , wherein the second transmission mode comprises at least one of the following: a data sending mode or a data receiving mode.

8 . The method according to claim 7 , wherein the data sending mode comprises at least one of the following:
that the terminal sends data in the Msg 3 in the 4-step random access procedure; that the terminal sends data in the Msg A in the 2-step random access procedure; that the terminal sends data in the dedicated uplink resource; that the network device sends data in the Msg 4 in the 4-step random access procedure; that the network device sends data in the Msg B in the 2-step random access procedure; or that the network device sends data in the downlink feedback resource corresponding to the dedicated uplink resource.

9 . The method according to claim 7 , wherein the date receiving mode comprises at least one of the following:
that the network device receives data in the Msg 3 in the 4-step random access procedure; that the network device receives data in the Msg A in a 2-step random access procedure; that the network device receives data in the dedicated uplink resource; that the terminal receives data in the Msg 4 in the 4-step random access procedure; that the terminal receives data in the Msg B in the 2-step random access procedure; or that the terminal receives data in the downlink feedback resource corresponding to the dedicated uplink resource.

10 . The method according to claim 1 , wherein the IN pieces of the transmission data comprise at least one of the following:
data of a data radio bearer (DRB); data of a quality of service flow; data of a protocol data unit (PDU) session; or a user plane data carried in a signaling radio bearer (SRB).

11 . The method according to claim 1 , wherein the configuration information is configured by the network device or agreed by a protocol.

12 . The method according to claim 11 , wherein when the configuration information is configured by the network device, the configuration information is carried in a radio resource control (RRC) release message or a system information block message.

13 . The method according to claim 1 , wherein before the performing matching between N pieces of the to-be-transmitted transmission data and a first condition, the method further comprises:
transmitting or receiving indication information, wherein the indication information is used to instruct the terminal to retain a context configuration, and the context configuration is used to resume a connection or resume data transmission.

14 . The method according to claim 1 , wherein
executing the first access procedure comprises: before the N pieces of the transmission data are transmitted, executing a first operation, wherein the first operation comprises any one of the following: when the N pieces of the transmission data are transmitted through an MCG bearer, resuming an MCG configuration of the bearer; when the N pieces of the transmission data are transmitted through an SCG bearer, resuming an SCG configuration of the bearer; when the NI pieces of the transmission data are transmitted through an MCG split bearer, resuming an MCG configuration of the bearer; when the N pieces of the transmission data are transmitted through an SCG split bearer, resuming an SCG configuration of the bearer; or when the N pieces of the transmission data are transmitted through the SCG split bearer, resuming a PDCP configuration and an MCG configuration of the SCG split bearer.

15 . The method according to claim 14 , wherein when only the configuration of the MCG bearer is resumed, the first operation further comprises: retaining and suspending the SCG configuration of the bearer.

16 . The method according to claim 14 , wherein when only the configuration of the SCG bearer is resumed, the first operation further comprises: retaining and suspending the MCG configuration of the bearer.

17 . The method according to claim 14 , wherein when the PDCP configuration and the MCG configuration of the SCG split bearer are resumed, the first operation further comprises at least one of the following:
resuming a configuration comprising MCG radio link control of the SCG split bearer in the MCG configuration; resuming a configuration comprising an MCG signaling radio bearer in the MCG configuration; or retaining and suspending a configuration of another DRB in the MCG configuration other than the SCG split bearer.

18 . A communications device, comprising:
a memory storing a computer program; and a processor coupled to the memory and configured to execute the computer program to perform operations comprising: performing matching between N pieces of to-be-transmitted transmission data and a first condition; and when the N pieces of the transmission data satisfy the first condition, executing a first access procedure-or-a-second-access-procedure, wherein the N pieces of transmission data are transmitted in the first access procedure,
