Method and device for communication processing

1 . A communication processing method, comprising:

receiving, by a user equipment (UE), multiple pieces of random access configuration information for a plurality of slices from a network device, wherein the network device configures respective random access configuration information for each of the plurality of slices, and wherein each random access configuration information comprises identification information of a corresponding slice and comprises a correspondence between the identification information of the corresponding slice and random access resources, the identification information of the corresponding slice comprises single network slice selection assistance information (S-NSSAI) or a slice/service type (SST) of the corresponding slice;

determining, by the UE, a target slice for which a random access is triggered;

in response to determining that identification information of the target slice is absent from the multiple pieces of random access configuration information, selecting by the UE, a common random access resource as a random access resource of the target slice; and

performing, by the UE, a random access on the random access resource of the target slice for which the random access is triggered.

2 . The method of claim 1 , further comprising:

determining the target slice for which the random access is triggered based on slice identification information provided when a non-access stratum requests an access stratum to initiate a radio resource control (RRC) connection.

3 . The method of claim 1 , further comprising:

determining the target slice for which the random access is triggered based on slice identification information carried in a physical downlink control channel (PDCCH) command when the PDCCH command triggers the random access of the UE.

4 . The method of claim 1 , wherein the target slice is identified by one of a S-NSSAI SST.

5 . A communication processing method, comprising:

determining, by a network device, multiple pieces of random access configuration information for a plurality of slices, wherein the network device configures respective random access configuration information for each of the plurality of slices, and each random access configuration information comprises identification information of a corresponding slice and comprises a correspondence between the identification information of the corresponding slice and random access resources, the identification information of the corresponding slice comprises single network slice selection assistance information (S-NSSAI) or a slice/service type (SST) of the corresponding slice; and

sending, by the network device, the multiple pieces of random access configuration information for the plurality of slices to a user equipment (UE) so that in a case that the identification information of a target slice is absent from the multiple pieces of random access configuration information, the UE selects a common random access resource as a random access resource of the target slice to perform a random access.

6 . A user equipment (UE), comprising:

a processor; and

a memory storing executable instructions;

wherein the processor is configured to perform the following:

receiving multiple pieces of random access configuration information from a network device for a plurality of slices, wherein the network device configures respective random access configuration information for each of the plurality of slices, and wherein each random access configuration information comprises identification information of a corresponding slice and comprises a correspondence between the identification information of the corresponding slice and random access resources, the identification information of the corresponding slice comprises single network slice selection assistance information (S-NSSAI) or a slice/service type (SST) of the corresponding slice;

determining a target slice for which a random access is triggered;

in response to determining that identification information of the target slice is absent from the multiple pieces of random access configuration information, selecting by the UE, a common random access resource as a random access resource of the target slice; and

performing the random access on the random access resource of the target slice for which the random access is triggered.

7 . A network device, comprising:

a processor; and

a memory storing executable instructions;

wherein the processor is configured to perform the communication processing method according to claim 5 .

8 . The UE of claim 6 , wherein the processor is further configured to perform the following:

determining the target slice for which the random access is triggered based on slice identification information provided when a non-access stratum requests an access stratum to initiate a radio resource control (RRC) connection.

9 . The UE of claim 6 , wherein the processor is further configured to perform the following:

determining the target slice for which the random access is triggered based on slice identification information carried in a physical downlink control channel (PDCCH) command when the PDCCH command triggers the random access of the UE.

10 . The UE of claim 6 , wherein the target slice is identified by one of a S-NSSAI and a SST.
