Abstract

The present disclosure provides a method for transmitting multicarrier-supported capability of UE. When the UE supports multicarrier, the UE sends a message carrying multicarrier-supported capability of the UE to an RNC; the RNC parses the message from the UE and obtains the multicarrier-supported capability of the UE. The present disclosure also provides a system for transmitting multicarrier-supported capability of UE. Through the method and the system of the present disclosure, a network side can learn that the UE supports multicarrier, and determine whether a service can be received by a multicarrier cell based on the learning.

Claims

1. A method for transmitting multicarrier-supported capability of User Equipment (UE), comprising:

sending out, by UE, a message carrying multicarrier-supported capability of the UE, when the UE supports multicarrier;

parsing, by an Radio Network Controller (RNC), a message carrying multicarrier-supported capability of UE received from the UE; and

obtaining the multicarrier-supported capability of the UE;

the method further comprises;

after the RNC obtains the multicarrier-supported capability of the UE,

deciding, by the RNC, that a service is received by a multicarrier cell, wherein the deciding comprises;

carrying, by the RNC, auxiliary carrier cell information in a radio link setup request message or in a radio link reconfiguration request message which is sent to a NodeB, and carrying the auxiliary carrier cell information in a radio bearer setup message or in a radio bearer reconfiguration message which is sent to the UE;

wherein the multicarrier-supported capability indicates the multicarrier-supported High Speed Downlink Packet Access (HSDPA) capability in a 3G system;

wherein the step of sending out, by the UE, the message carrying the multicarrier-supported capability of the UE comprises;

expanding a level of a High Speed-Downlink Shared Channel (HS-DSCH) physical layer category to add a level of the multicarrier supported capability of the UE; and

sending out an RRC connection setup complete message or a UE capability information message carrying the expanded HS-DSCH physical layer category when the UE supports multicarrier.

2. The method according to claim 1, wherein the RNC decides, according to Quality of Service (QoS) attribute, the multicarrier-supported capability of the UE and cell capability, that the service is received by the multicarrier cell.

3. A method for transmitting multicarrier-supported capability of User Equipment (UE), comprising:

sending out, by UE, a message carrying multicarrier-supported capability of the UE, when the UE supports multicarrier;

parsing, by an Radio Network Controller (RNC), a message carrying multicarrier-supported capability of UE received from the UE; and

obtaining the multicarrier-supported capability of the UE;

the method further comprises;

after the RNC obtains the multicarrier-supported capability of the UE,

deciding, by the RNC, that a service is received by a multicarrier cell, wherein the deciding comprises;

carrying, by the RNC, auxiliary carrier cell information in a radio link setup request message or in a radio link reconfiguration request message which is sent to a NodeB, and carrying the auxiliary carrier cell information in a radio bearer setup message or in a radio bearer reconfiguration message which is sent to the UE;

wherein the multicarrier-supported capability indicates the multicarrier-supported High Speed Downlink Packet Access (HSDPA) capability in a 3G system;

wherein the step of sending out, by the UE, the message carrying the multicarrier-supported capability of the UE comprises;

expanding a value of an information element of double carrier-supported capability of the UE in R8 protocol, wherein the expanded value is used for indicating a capability that how many multicarrier the UE supports; and

sending out an RRC connection request message carrying the expanded information element when the UE supports multicarrier.

4. A system for transmitting multicarrier-supported capability of User Equipment (UE), comprising a UE and a Radio network Controller (RNC), wherein

the UE is configured to send out a message carrying multicarrier-supported capability of the UE when the UE supports multicarrier;

the RNC is configured to parse a message carrying multicarrier-supported capability of UE received from the UE and obtain the multicarrier-supported capability of the UE;

wherein the RNC is further configured to, after obtaining the multicarrier-supported capability of the UE, decide that a service is received by a multicarrier cell, wherein the deciding comprises;

auxiliary carrier cell information is carried, by the RNC, in a radio link setup request message or in a radio link reconfiguration request message which is sent to a NodeB, and the auxiliary carrier cell information is carried in a radio bearer setup message or in a radio bearer reconfiguration message which is sent to the UE;

wherein the multicarrier-supported capability indicates the multicarrier-supported High Speed Downlink Packet Access (HSDPA) capability in a 3G system;

wherein the UE is further configured to expand a level of an HS-DSCH physical layer category to add a level of the multicarrier-supported capability of the UE; and

to send out an RRC connection setup complete message or a UE capability information message carrying the expanded HS-DSCH physical layer category when the UE supports multicarrier.

5. The system according to claim 4, wherein the RNC is further configured to decide, according to QoS attribute, the multicarrier-supported capability of the UE and cell capability, that the service is received by the multicarrier cell.

6. A system for transmitting multicarrier-supported capability of User Equipment (UE), comprising a UE and a Radio Network Controller (RNC), wherein

the UE is configured to send out a message carrying multicarrier-supported capability of the UE when the UE supports multicarrier;

the RNC is configured to parse a message carrying multicarrier-supported capability of the UE received from the UE and obtain the multicarrier-supported capability of the UE;

wherein the RNC is further configured to, after obtaining the multicarrier-supported capability of the UE, decide that a service is received by a multicarrier cell, wherein the deciding comprises;

auxiliary carrier cell information is carrier, by the RNC, in a radio link setup request message or in a radio link reconfiguration request message which is sent to a NodeB, and the auxiliary carrier cell information is carrier in a radio bearer setup message or in a radio bearer reconfiguration message which is sent to the UE;

wherein the multicarrier-supported capability indicates the multicarrier-supported High Speed Downlink Packet Access (HSDPA) capability in a 3G system;

wherein the UE is further configured to expand a value of an information element of double carrier-supported capability of the UE in R8 protocol, wherein the expanded value is used for indicating a capability that how many multicarrier the UE supports; and

to send out an RRC connection request message carrying the expanded information element when the UE supports multicarrier.
