This method may further include:
In the resource distribution tabulation of system information block 5, increase the frequency point information cell of each public E-FACH resource sharing in advance at public E-FACH resource; Described frequency point information cell is optional cell, when described frequency point information cell does not occur, represent the resource that described public E-FACH resource is a main carrier, when described frequency point information cell occurred, the value of described frequency point information cell was represented the resource that described public E-FACH resource is the pairing auxilliary carrier wave of described value;
Described A can comprise: determine the carrier wave that the sub-district is positioned at, the public E-FACH configuration information of resource of described carrier wave is carried in the resource distribution tabulation of described system information block 5 or system information block 6, judge whether described carrier wave is auxilliary carrier wave, if auxilliary carrier wave, increase described frequency point information cell, and fill described frequency point information cell with the frequency point information of described auxilliary carrier wave.
Described in advance in the resource distribution of system information block 5 tabulation at each public E-FACH resource increase a frequency point information cell can for:
In resource distribution tabulation, the frequency point information unit is set respectively in advance at described common E-DCH resource, public HS-DSCH resource, the public HS-DSCH resource that is used for paging and the HS-DSCH discontinuous reception parameters under the CELL_FACH state at system information block 5.
As seen from the above technical solution, the present invention is by configuration common E-DCH and public HS-DSCH resource on the auxilliary carrier wave of TD-SCDMA system, making UE to carry out E-DCH on the CCCH of auxilliary carrier wave inserts, and can on the public HS-DSCH resource that CCCH shone upon of auxilliary carrier wave, receive downlink signaling or data, thereby reduced the collision probability that E-DCH inserts on the main carrier, and made auxilliary carrier resource obtain utilizing flexibly and fully.
Description of drawings
Fig. 1 carries out the schematic flow sheet of the method for common channel resources configuration on auxilliary carrier wave for the present invention.
Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Main thought of the present invention is: by configuration public enhancing forward access channel (E-FACH) resource on the auxilliary carrier wave of TD-SCDMA system, comprise: the common E-DCH resource, public HS-DSCH resource, be used for the public HS-DSCH resource of paging and the discontinuous reception of HS-DSCH (DRX) parameter under the CELL_FACH state, making UE to carry out E-DCH on the CCCH of auxilliary carrier wave inserts, and can on the public HS-DSCH resource that CCCH shone upon of auxilliary carrier wave, receive downlink signaling or data, thereby reduced the collision probability that E-DCH inserts on the main carrier, and made auxilliary carrier resource obtain utilizing flexibly and fully.
Fig. 1 carries out the schematic flow sheet of the method for common channel resources configuration on auxilliary carrier wave for the present invention.Referring to Fig. 1, this method comprises:
Step 101: the public E-FACH configuration information of resource that will assist carrier wave is carried in the resource distribution tabulation of system information block.
The invention provides the mode in the resource distribution tabulation that the following two kinds of public E-FACH configuration information of resource that will assist carrier wave are carried on system information block:
First kind of mode:
In the TD-SCDMA system, SIB5/SIB5-bis (system information block 5) is used for disposing down to the UE broadcast idle mode parameter information of public physic channel.First kind of mode provided by the invention is to be implemented on the auxilliary carrier wave by SIB5/SIB5-bis to dispose common channel resources.
For this reason, at first in the resource distribution tabulation of SIB5/SIB5-bis, increase a frequency point information cell at each public E-FACH resource; This frequency point information cell is optional cell, when the frequency point information cell does not occur, represent the resource that corresponding public E-FACH resource is a main carrier, when the frequency point information cell occurred, the value of frequency point information cell was represented the resource that corresponding public E-FACH resource is the pairing auxilliary carrier wave of this value.That is to say: in the resource distribution tabulation of SIB5/SIB5-bis, the frequency point information unit is set respectively at common E-DCH resource, public HS-DSCH resource, the public HS-DSCH resource that is used for paging and the HS-DSCH DRX parameter under the CELL_FACH state.Specifically as shown in table 1:
Table 1
Then, the public E-FACH configuration information of resource of main carrier and auxilliary carrier wave is carried in the resource distribution tabulation of SIB5/SIB5-bis, for the public E-FACH configuration information of resource that belongs to auxilliary carrier wave in the resource distribution tabulation, increase corresponding frequency point information cell, and fill this frequency point information cell with the frequency point information of this auxilliary carrier wave.
The second way:
The second way provided by the invention is to be implemented on the auxilliary carrier wave by SIB5/SIB5-bis to dispose common channel resources.
For this reason, at first in the resource distribution tabulation of SIB5/SIB5-bis, increase the frequency point information cell of each public E-FACH resource sharing at public E-FACH resource; This frequency point information cell is optional cell, when the frequency point information cell does not occur, represent that public E-FACH resource is the resource of main carrier, when the frequency point information cell occurred, the value of this frequency point information cell represented that public E-FACH resource is the resource of the pairing auxilliary carrier wave of this value.Specifically as shown in table 2:
Table 2
Then, determine the carrier wave that the sub-district is positioned at, the public E-FACH configuration information of resource of described carrier wave is carried in the resource distribution tabulation of described SIB 5/SIB 6, judge whether this carrier wave is auxilliary carrier wave, if auxilliary carrier wave, increase the frequency point information cell, and fill the frequency point information cell with the frequency point information of this auxilliary carrier wave.
Adopt the above-mentioned second way can simplify configuration, and reduce modification system message.
Step 102: to UE broadcasting said system block of information.
So far, finish the present invention carries out the common channel resources configuration on auxilliary carrier wave method.
As seen from the above-described embodiment, the present invention is by configuration common E-DCH and public HS-DSCH resource on the auxilliary carrier wave of TD-SCDMA system, making UE to carry out E-DCH on the CCCH of auxilliary carrier wave inserts, and can on the public HS-DSCH resource that CCCH shone upon of auxilliary carrier wave, receive downlink signaling or data, thereby reduced the collision probability that E-DCH inserts on the main carrier, and made auxilliary carrier resource obtain utilizing flexibly and fully.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.All any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
