Description

A kind of sub-carrier configuration strengthens method, system and the equipment of CELL_FACH

Technical field

The present invention relates to wireless communication technology field, particularly relate to method, system and equipment that a kind of sub-carrier configuration strengthens CELL_FACH.

Background technology

At TD-SCDMA (Time Division-Synchronous Code Division MultipleAccess, TD SDMA inserts) system, introduced N frequency characteristic among the 3GPP Release7 (The Third-GenerationMobile Communications Partnership Program Release7, the 3G (Third Generation) Moblie partner plans version 7).In the system of N frequency, the carrier wave of a sub-district is divided into two kinds of main carrier and auxilliary carrier waves, but terminal can only be operated on the carrier wave simultaneously.Network side can pass through RRC (Radio Resource Control, Radio Resource control) connect foundation, RB (Radio Bearer, radio bearer) sets up, and reshuffle special RRC signalings such as signaling terminal configuration is worked to different carrier waves, and system message broadcast transmission on main carrier only.

At the TD-SCDMA system, introduced enhancing CELL_FACH (Forward Access Channel, forward access channel) characteristic among the 3GPP Release8.In traditional CELL_FACH state, do not give the terminal distribution dedicated channel, terminal receives low volume data at descending monitoring FACH, at up use RACH (Random Access Channel, Random Access Channel) transmission low volume data.Because the modulation system of the physical resource that FACH and RACH shone upon restriction and low order is so message transmission rate is lower under this state.In strengthening the CELL_FACH characteristic, with HSDPA (High SpeedDownlink Packet Access, high speed downlink packet inserts) and correlated channels and the transmission mechanism of HSUPA (High Speed UplinkPacket Access, high speed uplink packet access) be incorporated into the CELL_FACH state.Like this, under the CELL_FACH state, downlink data is mapped to HS-DSCH (High Speed Downlink Share Channel, high speed descending sharing channel) on, HS-DSCH is mapped to HS-PDSCH (High Speed Downlink Physical Share Channel, high-speed downstream Physical Shared Channel) and goes up transmission.Upstream data is mapped on the E-DCH (Enhanced Dedicated Channel strengthens dedicated channel), and E-DCH is mapped to E-PUCH (E-DCH Physical Uplink Channel, E-DCH physical uplink channel) and goes up transmission.Transmission rate by signaling under such data transfer mode raising CELL_FACH state reduces the signaling propagation delay time, uses discontinuous reception technique to reduce the power consumption of terminal under the CELL_FACH state simultaneously.

In the prior art, terminal need report whether support to strengthen the CELL_FACH characteristic to network side when the RRC connection is set up.If network side supports to strengthen the CELL_FACH characteristic equally, then can pass through SIB5 (System information block 5, system broadcast information piece 5) and in system message, carry enhancing CELL_FACH parameter, indication possesses this characteristic; If above-mentioned parameter in system message, do not occur, illustrate that then network side do not support to strengthen the CELL_FACH characteristic, and then the terminal in this network can not strengthen the CEL_FACH characteristic.

The enhancing CELL_FACH parameter of carrying in the system message only is used for the enhancing CELL_FACH operation on the main carrier.When terminal and network side have all started enhancing CELL_FACH characteristic, strengthening the needed HS-DSCH of the CELL_FACH parameter relevant with E-DCH on the so auxilliary carrier wave can be by the relevant enhancing CELL_FACH parameter acquisition of carrying in configuration of special RRC signaling and the system message.

In realizing process of the present invention, the inventor finds prior art, and there are the following problems at least:

In the prior art, have only and disposed enhancing CELL_FACH parameter on main carrier, promptly terminal has been received and has been carried in the system message when strengthening the CELL_FACH parameter, just can strengthen the CELL_FACH operation.Otherwise terminal only can be carried out traditional CELL_FACH operation.So, can be although strengthen the needed HS-DSCH of the CELL_FACH parameter relevant on the auxilliary carrier wave by the configuration of special RRC signaling with E-DCH, if but main carrier does not dispose enhancing CELL_FACH parameter, terminal still can not strengthen the CELL_FACH operation, can not satisfy the networking characteristic of N frequency well.

Below in conjunction with concrete application scenarios, the present invention is further introduced.

Provide a kind of sub-carrier configuration to strengthen the method for CELL_FACH in the embodiment of the invention two, whether employing increases main carrier and supports the mode that strengthens the indication of CELL_FACH characteristic to dispose enhancing CELL_FACH in system message, concrete steps may further comprise the steps as shown in Figure 2:

Step 201, network side generate about the configuration that strengthens the CELL_FACH parameter and are carried at and send to terminal in the system message.

Receiving network side sends about strengthening in the following multiple situation any of being configured to of CELL_FACH parameter:

(1) network side sends the indication information whether the enhancing CELL_FACH parameter be carried in the system message and main carrier support to strengthen the CELL_FACH characteristic;

(2) network side sends enhancing CELL_FACH parameter that is carried in the system message and the carrier frequency information that strengthens CELL_FACH parameter correspondence;

(3) network side sends the enhancing CELL_FACH parameter that is carried in system message or the special RRC signaling.

Obtain the configuration of the relevant CELL_FACH of enhancing parameter in this flow process with network side, and in system message, carry to example by SIB5 and to describe.

The enhancing CELL_FACH parameter that comprises among the SIB 5 comprises: strengthen the descending ability parameter of CELL_FACH " HS-DSCH common system information ", strengthen PCH parameter " HS-DSCH paging system information 1.28Mcps TDD ", strengthen CELL_FACH upward line parameter " Common E-DCH system info " and enhancing DRX ability parameter " HS-DSCHDRX in CELL_FACH Information 1.28 Mcps TDD ".

Strengthen the parameter of carrying in the descending ability parameter of CELL_FACH " HS-DSCH common systeminformation " and mainly contain " CCCH mapping info ", " SRB1 mappinginfo ", " Common MAC-ehs reordering queue list ", " HS-SCCH system in fo ", " HARQ system Info ", " Common H-RNTI Information " and " BCCH spe cificH-RNTI ".

Need illustrate, when network side is not supported to strengthen the CELL_FACH characteristic, will not carry enhancing CELL_FACH parameter in the system message.

Step 202, terminal are according to strengthening the CELL_FACH parameter about whether carrying in the configuration that strengthens the CELL_FACH parameter, and whether main carrier supports the indication information that strengthens the CELL_FACH characteristic to judge whether main carrier supports to strengthen the CELL_FACH characteristic.

Enhancing CELL_FACH parameter is the various parameters in the above-mentioned steps 202.

Whether main carrier strengthens the indication information of CELL_FACH characteristic, is used to indicate main carrier whether to support to strengthen the CELL_FACH characteristic.Preferably, not support to strengthen the indication information of CELL_FACH characteristic be that example describes to carry main carrier in the embodiment of the invention, and this indication information is by IE " PrimaryFrequency eFACH Indicator " expression.Concrete, in system information, do not carry IE " PrimaryFrequency eFACH Indicator ", show that then the main carrier support strengthens the CELL_FACH characteristic; In system information, carry IE " Primary Frequency eFACH Indicator ", show that then main carrier do not support to strengthen the CELL_FACH characteristic.

Concrete, terminal is according to about strengthening the configuration of CELL_FACH parameter, judges whether main carrier is supported to strengthen the CELL_FACH characteristic and comprised in following two kinds of situations any:

1) in system message, carries enhancing CELL_FACH parameter, go up line parameter " Common E-DCH system info " comprising strengthening the descending ability parameter of CELL_FACH " HS-DSCH common system information " and strengthening CELL_FACH, and when not carrying main carrier enhancing CELL_FACH indication IE " Primary Frequency eFACH Indicator ", the support of terminal judges main carrier strengthens the CELL_FACH characteristic.

2) in system message, carry enhancing CELL_FACH parameter, go up line parameter " Common E-DCH system info " comprising strengthening the descending ability parameter of CELL_FACH " HS-DSCH common system information " and strengthening CELL_FACH, and when carrying main carrier enhancing CELL_FACH indication IE " Primary Frequency eFACH Indicator ", the terminal judges main carrier does not support to strengthen the CELL_FACH characteristic.

Whether step 203, terminal judges start strengthens the CELL_FACH characteristic.

Concrete, whether terminal judges starts enhancing CELL_FACH characteristic need be carried out judgment variable by the value of first variable and second variable.Wherein the value of first variable is relevant with the EDCH ability that network side and terminal all have; The value of second variable is relevant with the HS_DSCH ability that network side and terminal all have.

When the value of first variable and second variable is true time, terminal judges starts and strengthens the CELL_FACH characteristic;

When arbitrary value of first variable and second variable is a fictitious time, terminal judges does not start and strengthens the CELL_FACH characteristic.

Judgment mechanism in this flow process comprises one or more in the following mode:

Terminal works is when main carrier, if meet the following conditions simultaneously: (1) terminal is supported the E-DCH transmission under CELL_FACH or idle pulley; (2) carry enhancing CELL_FACH parameter in the system information; (3) do not carry the indication information that main carrier does not support to strengthen CELL_FACH in the system information; Then the value of first variable is true, otherwise the value of first variable is false;

Terminal works is when assisting carrier wave, if meet the following conditions simultaneously: (1) terminal is supported the E-DCH transmission under CELL_FACH or idle pulley; (2) carry enhancing CELL_FACH parameter in the system information; (3) carry enhancing CELL_FACH parameter in the special RRC signaling; Then the value of first variable is true, otherwise the value of first variable is false;

Terminal works is when main carrier, if meet the following conditions simultaneously: (1) terminal is supported the HS-DSCH operation; (2) carry enhancing CELL_FACH parameter in the system information; (3) do not carry the indication information that main carrier does not support to strengthen CELL_FACH in the system information; Then the value of second variable is true, otherwise the value of second variable is false;

Terminal works is when assisting carrier wave, if meet the following conditions simultaneously: (1) terminal is supported the HS-DSCH operation; (2) carry enhancing CELL_FACH parameter in the system information; (3) carry enhancing CELL_FACH parameter in the special RRC signaling; Then the value of second variable is true, otherwise the value of second variable is false.

Based on above-mentioned judgment mechanism, when the support of terminal judges main carrier strengthens the CELL_FACH characteristic, whether terminal judges starts strengthens the CELL_FACH characteristic, and carries out corresponding operating at the main carrier at work at present place or auxilliary carrier wave and specifically comprise in following two kinds of situations any:

1) when terminal works during at main carrier, terminal puts first variable and second variable is TRUE, judges to start to strengthen the CELL_FACH characteristic; Terminal utilizes the enhancing CELL_FACH parameter of system message configuration to start enhancing CELL_FACH characteristic at main carrier.

2) carry in auxilliary carrier wave and special RRC signaling when terminal works and strengthen the CELL_FACH parameter, for example " E-DCH Info ", when " Downlink HS-PDSCH Information " etc., terminal is put first variable and second variable is TRUE, judges to start to strengthen the CELL_FACH characteristic.

When the terminal judges main carrier was not supported to strengthen the CELL_FACH characteristic, whether terminal judges starts strengthened the CELL_FACH characteristic, and handled accordingly and specifically comprise in following two kinds of situations any:

1) when terminal works during at main carrier, terminal puts first variable and second variable is FALSE, judges not start to strengthen the CELL_FACH characteristic; Terminal does not start at main carrier and strengthens the CELL_FACH characteristic.

2) when terminal works during at auxilliary carrier wave, and carry in the special RRC signaling and strengthen CELL_FACH parameter, for example " E-DCH Info ", " Downlink HS-PDSCH Information " etc., terminal puts first variable and second variable is TRUE, judges to start to strengthen the CELL_FACH characteristic.

Wherein, first variable is a true time, and terminal needs to support the E-DCH transmission under CELL_FACH or idle pulley; Second variable is a true time, and terminal needs to support the HS-DSCH operation under the CELL_FACH pattern.

Step 204, terminal are carried out corresponding operating according to the main carrier or the auxilliary carrier wave of judged result at the work at present place.

Concrete, terminal is handled according to judged result and is comprised in following two kinds of situations any:

1) when judged result strengthens the CELL_FACH characteristic for starting, enhancing CELL_FACH parameter configuration physical layer and MAC (Medium Access Control that main carrier or the auxilliary carrier wave utilization of terminal at the work at present place received, medium is got involved control) layer, and further judge whether to utilize HS-DSCH and E-DCH to carry out transfer of data.

Need to prove, auxilliary carrier wave starts the required enhancing CELL_FACH parameter of enhancing CELL_FACH characteristic and is disposed by the special RRC signaling, when the required enhancing CELL_FACH parameter special RRC signaling configuration of auxilliary carrier wave startup enhancing CELL_FACH characteristic is not disposed, obtain in the enhancing CELL_FACH parameter that will from system message, carry.For example, auxilliary carrier wave starts and strengthens required enhancing CELL_FACH parameter " BCCH specific H-RNTI " and " the CCCH transmission info " of CELL_FACH characteristic, not configuration of special RRC signaling configuration is upward obtained descending ability parameter of enhancing CELL_FACH in the enhancing CELL_FACH parameter of carrying respectively " HS-DSCH common system information " and enhancing CELL_FACH from system message in the line parameter " Common E-DCH system info ".

2) when judged result strengthens the CELL_FACH characteristic for not starting, terminal does not start enhancing CELL_FACH characteristic at the main carrier or the auxilliary carrier wave at work at present place, utilizes FACH and RACH transmission data.

At this moment, the sub-carrier configuration that provides of the embodiment of the invention method that strengthens CELL_FACH exerts an influence as follows to standard 25.331:

Wherein, the embodiment of the invention exerts an influence to having increased Primary FrequencyeFACH Indicator (main carrier frequency strengthens the FACH indication) to standard 25.331, when this indication not occurring, show that the main carrier frequency support strengthens FACH, be used for judging whether to start enhancing CELL_FACH characteristic according to above-mentioned judgment mechanism.
