Cell radio network temporary identifier C-RNTI allocation method and device

A device, comprising:

• a processor;
• and
• a non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium stores a program, and the processor executes the program to:
• randomly determine a start position of a cell radio network temporary identifier (C-RNTI) interval range for selecting a C-RNTI when a user equipment (UE) accesses a serving cell, wherein the C-RNTI interval range is smaller than a C-RNTI value range;
• randomly select a C-RNTI for the UE from the C-RNTI interval range;
• and
• allocate the selected C-RNTI to the UE.

A system, comprising:

• a first entity at which a primary component carrier (PCC) of a user equipment (UE) is located;
• and
• a second entity at which a secondary component carrier (SCC) of the UE is located;
• wherein the first entity is configured to:
• select a cell radio network temporary identifier (C-RNTI) for the UE, wherein selecting the C-RNTI for the UE comprises:
• randomly determine a start position of a cell radio network temporary identifier (C-RNTI) interval range for selecting the C-RNTI when the UE accesses the PCC, wherein the C-RNTI interval range is smaller than a C-RNTI value range;
• and
• randomly select a C-RNTI for the UE from the C-RNTI interval range;
• allocate the C-RNTI to the UE;
• and
• send the selected C-RNTI to the entity at which the SCC is located;
• wherein the second entity is configured to:
• receive the C-RNTI selected by the first entity;
• determine whether the C-RNTI is allocated to another UE for use;
• and
• allocate the C-RNTI to the UE when it is determined that the C-RNTI is not allocated to another UE for use.
