Abstract

An apparatus and a method for allocating identifiers (IDs) which differentiate data to be transmitted in a mobile communication system supporting the transmission of packet data. The method is used for allocating identifiers to packet data by a radio network controller (RNC) so as to differentiate packet data in a mobile communication system which includes the RNC and a user equipment (UE), wherein the RNC transmits the packet data to a certain cell through at least two common channels including at least two transport channels and the UE receives the packet data through the transport channel. The method includes the steps of: determining a transport channel for transmitting received packet data; and allocating dedicated identifiers for differentiating the pack data according to the determined transport channels.

Claims

1. A method for allocating identifiers to packet data by a radio network controller (RNC) for differentiating packet data services in a mobile communication system including the RNC for supporting the packet data services and a user equipment (UE) for receiving the packet data service transmitted from the RNC, the method comprising the steps of:

generating a cell identifier for differentiating cells managed by the RNC;

generating a channel identifier for differentiating channels constructed according to each cell;

generating a packet service identifier for differentiating the packet data services in each channel identifier;

allocating the generated identifiers to the received packet data service; and

transmitting the allocated packet data service through a determined channel.

2. The method as claimed in claim 1, wherein the packet service identifiers for differentiating the packet data service in the channel identifier are managed using an identification (ID) pool.

3. The method as claimed in claim 2, wherein, the ID pool is managed so as to generate an identifier having a minimum value from among first identifiers which are not overlapped with secondary identifiers allocated to each of packet data services.

4. A method for allocating identifiers to packet data by a radio network controller (RNC) for differentiating packet data services in a mobile communication system including the RNC for supporting the packet data services and a user equipment (UE) for receiving the packet data service transmitted from the RNC, the method comprising the steps of:

determining a transport channel for transmitting received packet data;

generating an identifier that is not overlapped with identifiers which are allocated to the packet data services transmitted through a common channel including the determined transport channel;

allocating the generated identifier to the received packet data service; and

transmitting the packet data service having been allocated the identifier through the determined channel.

5. The method as claimed in claim 4, wherein, the step of generating an identifier generates an identifier having a minimum value from among first identifiers which are not overlapped with secondary identifiers allocated to the respective packet data services.

6. An apparatus for allocating identifiers to packet data by a radio network controller (RNC) for differentiating packet data services in a mobile communication system including the RNC for supporting the packet data services and a user equipment (UE) for receiving the packet data service transmitted from the RNC, the apparatus comprising:

a storage unit for storing transport channels and identifiers which are allocated to packet data services transmitted through respective transport channels; and

a controller for determining a transport channel for transmitting received packet data and for generating an identifier that is not overlapped with identifiers which are allocated to each packet data service transmitted through the determined transport channel.

7. The apparatus as claimed in claim 6, wherein the controller generates an identifier having a minimum value from among first identifiers which are not overlapped with secondary identifiers allocated to the respective packet data services.

8. A method for allocating identifiers to packet data by a radio network controller (RNC) for differentiating packet data in a mobile communication system including the RNC and a user equipment (UE), wherein the RNC transmits the packet data to a certain cell through at least two common channels including at least two transport channels and the UE receives the packet data through the transport channel, the method comprising the steps of:

determining a transport channel for transmitting received packet data;

generating an identifier that is not overlapped with identifiers which are allocated to packet data being transmitted through the determined transport channel; and

allocating the generated identifier to the packet data to be transmitted.

9. The method as claimed in claim 8, wherein the identifiers which can be generated according to each channel are identical to each other.

10. A method for allocating identifiers to packet data by a radio network controller (RNC) for differentiating packet data in a mobile communication system which includes the RNC and a user equipment (UE), wherein the RNC transmits the packet data to a certain cell through at least two common channels including at least two transport channels and the UE receives the packet data through the transport channels, the method comprising the steps of:

generating a cell identifier for differentiating cells managed by the RNC;

generating a common channel identifier for differentiating common channels constructed according to each cell;

generating a channel identifier for differentiating channels constructed according to each common channel;

generating a packet service identifier for differentiating the packet data services in each channel identifier;

allocating the generated identifiers to the received packet data service; and

transmitting the allocated packet data service through a determined channel.

11. A method for allocating identifiers to packet data by a radio network controller (RNC) for differentiating packet data services in a mobile communication system including the RNC for supporting the packet data services and a user equipment (UE) being provided with the packet data service transmitted from the RNC, the method comprising the steps of:

allocating dedicated identifiers, which are not overlapped with each other, to the packet data by the RNC for differentiating the packet data in a transport channel through which the packet data are transmitted; and

transmitting the packet data including the dedicated identifier to the UE through a determined transport channel.

12. The method as claimed in claim 11, wherein the RNC allocates the dedicated identifier for differentiating the packet data according to forward packet access channels (FACHs).

13. A method for allocating identifiers to packet data by a radio network controller (RNC) for differentiating packet data services in a mobile communication system including the RNC for supporting the packet data services and a user equipment (UE) being provided with the packet data service transmitted from the RNC, the method comprising the steps of:

allocating dedicated identifiers, which are not overlapped with each other, to the packet data by the RNC for differentiating the packet data in a physical channel including at least two transport channels; and

transmitting the packet data including a dedicated identifier to the UE through a determined physical channel.

14. The method as claimed in claim 13, wherein the RNC allocates the dedicated identifier according to secondary-common control physical channels (S-CCPCHs) for differentiating the packet data.
