Abstract
A cell radio network temporary identifier (C-RNTI) allocation method and device are disclosed. The method includes: when UE accesses a serving cell, randomly determining, by an entity at which the serving cell is located, a start position for selecting a C-RNTI, selecting a C-RNTI for the UE within a C-RNTI interval range starting from the start position, and allocating the selected C-RNTI to the UE. So the entity at which the serving cell is located randomizes the start position of allocation performed by the entity and uses the start position as a start position of an allocation interval, so that allocation of the C-RNTI is randomized.
Claims24
A method, comprising:
- randomly determining, by an entity at which a serving cell is located, a start position for selecting a cell radio network temporary identifier (C-RNTI) from a C-RNTI value range when a user equipment (UE) accesses the serving cell;
- selecting, by the entity at which the serving cell is located, a C-RNTI for the UE from a C-RNTI interval range, wherein the interval range is smaller than the C-RNTI value range, and a start position of the interval range is the determined start position;
- and
- allocating, by the entity at which the serving cell is located, the selected C-RNTI to the UE.
A method, comprising:
- receiving, by an entity at which a secondary component carrier (SCC) is located, a cell radio network temporary identifier (C-RNTI) sent by an entity at which a primary component carrier (PCC) is located, wherein the C-RNTI is selected by the entity at which the PCC is located for a user equipment (UE) from a C-RNTI interval range, a start position of the interval range is randomly determined, and the interval range is smaller than a C-RNTI value range, and wherein the SCC and the PCC are component carriers of carrier aggregation (CA) supported by the UE;
- determining, by the entity at which the SCC is located, whether the C-RNTI is allocated to another UE for use;
- and
- allocating, by the entity at which the SCC is located, the C-RNTI to the UE when it is determined that the C-RNTI is not allocated to another UE for use.
The method according to claim ii, wherein the plurality of C-RNTIs are randomly selected by the entity at which the PCC is located for the UE from the interval range.
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 for selecting a cell radio network temporary identifier (C-RNTI) from a C-RNTI value range when a user equipment (UE) accesses a serving cell;
- select a C-RNTI for the UE from a C-RNTI interval range, wherein the interval range is smaller than the C-RNTI value range, and a start position of the interval range is the determined start position;
- and
- allocate the selected C-RNTI to the UE.
A cell radio network temporary identifier (C-RNTI) allocation device, configured to allocate a C-RNTI to user equipment (UE) supporting carrier aggregation (CA), wherein component carriers of the CA comprise a primary component carrier (PCC) and a secondary component carrier (SCC), and the device comprises:
- 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:
- receive a C-RNTI sent by an entity at which the PCC is located, wherein the C-RNTI is selected by the entity at which the PCC is located for the UE from a C-RNTI interval range, a start position of the interval range is randomly determined, and the interval range is smaller than a C-RNTI value range;
- 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.
