Procedure of data transmission, network system and related device Field of technology

The present invention relates to the field of mobile communications and, more particularly, to a data transmission method, a network system and a related device.

Background of the invention

In third-generation (3G) radio networks, user equipment (UE) has two states, ie an inactive mode and a connected mode. The connected mode is further classified into four states, namely, dedicated cell channel (CELL_DCH), cell direct access channel (CELL_FACH), cell radiolocation channel (CELL_PCH) and radiolocation channel of network registration area. terrestrial radioelectric access of the universal mobile telecommunications system (URA_PCH). The basic characteristic of the CELL_FACH state is that there is no dedicated physical channel connection between the UE and the radioelectric access network, and the UE continuously monitors a FACH transmission channel in a downlink direction and uses a common transmission channel or shared, for example a random access channel (RACH), in an uplink direction, so that the UE can initiate an access process in an associated transmission channel at any time.

The improved CELL_FACH status is a new technique that has been developed based on the CELL_FACH technique of the Third Generation Partnership Project (3GPP), R7.

In the enhanced CELL_FACH state, downlink data carried on a FACH transmission channel can be passed on to a high-speed downlink shared channel (HS-DSCH) to increase the data transmission rate in the CELL_FACH state and reduce the delay of the transition between states.

As seen from the technical characteristics of the improved CELL_FACH state and normalized according to R7, in the enhanced CELL_FACH state the downlink user data can be transmitted to the UE through the HS-DSCH, which shares the downlink resources with the UE in the CELL_DCH state, so that the UE in the CELL_FACH state can also establish high-speed data transmissions in the downlink just like a UE in the CELL_DCH state.

In the unimproved CELL_FACH state, the data transmission rate is generally less than 32 Kbps, and the high-speed downlink data transmission can not be carried out until the state of the UE passes to the CELL_DCH state. On the other hand, in the enhanced CELL_FACH state, the high-speed downlink data transmission can be carried out without the UE passing into the CELL_DCH state, so that the time required by the state transition from the original CELL_FACH state to the CELL_DCH status to carry out the high-speed data transmission is greatly reduced and the data transmission speed increases.

However, in the current enhanced CELL_FACH state, a network radio transceiver, for example a radio base station (Node B) or an Evolved Node B (E-NodeB), does not know the capability category of the UE that implements the reception of enhanced CELL_FACH in the current cell, so that the radio transceiver can only perform a combination of resources and transport formats (TFRC) in enhanced CELL_FACH data queues using a scheduling algorithm based on the category of lower capacity of the UE, thereby generating limitations in the speed of data transmission.

In the US patent application US2007 / 258402A1 a user equipment for communicating data in a communication system is disclosed. The user equipment comprises: a transceiver arranged to receive at least one data packet through a communication channel, where the data packet comprises an identifier; and a processor arranged to determine from the identifier whether said user equipment is one of a subset of user equipment, where the processor is arranged to determine whether the first identifier is one of the subset of user equipment when the identifier matches a first value if the communication channel is a common channel or with a second value if the communication channel is a dedicated channel.

Detailed description of the forms of realization

Currently, the improved CELL_FACH technique defined by the 3GPP R7 standard protocol is normally implemented in the following process:

1. A UE supporting an improved CELL_FACH state first monitors the HS-DSCH common system information IE transported in a system information block type 5 and 5bis message broadcast in a cell and configures basic parameters required by the Improved CELL_FACH status, where a common H-RNTI and a BCCH-specific H-RNTI should be included.

Here, IE is the abbreviation of information element, RNTI is the abbreviation of radio network temporary identifier, H-RNTI is the abbreviation of HS-DSCH-RNTI and BCCH is the abbreviation of broadcast control channel.

2. The UE transports a high-speed shared downlink (HS-PDSCH) physical channel support in a CELL_FACH IE and a MAC-ehs IE support in a RRC CONNECT REQUEST message to inform a controller of radio network (RNC) that the UE supports the enhanced CELL_FACH (E-FACH).

Here, RRC is the abbreviation of control of radio resources and MAC is the abbreviation of control of access to the medium.

3. If the RNC knows that the cell in which the UE currently resides also supports the E-FACH mode, the RNC can indicate that the UE is in the CELL_FACH state and can configure other parameters related to the HS-DSCH reception in a RRC connection establishment message, where the related parameters include a dedicated H-RNTI.

4. The UE returns an RRC connection establishment termination message and the message can carry the HS-DSCH physical layer category of the UE. At this time, the UE is in a state in which it monitors a physical high-speed downlink shared control (HS-SCCH) channel.

5. When a signaling or data message needs to be transmitted through the BCCH, the common control channel (CCCH), the dedicated control channel (DCCH) and the dedicated traffic channel (DTCH), the RNC transmits the signaling or data to a Node B through a HS-DSCH data frame (eg, HS-DSCH data frame TYPE2) of an Iub interface (ie, an interface between the RNC and the Node B) and, for On the other hand, it carries a corresponding H-RNTI in the data frame.

6. When planning the data according to a queue priority, the Node B carries out a different TFRC selection processing according to the H-RNTI category transported in the HS-DSCH data frame (hereinafter referred to briefly). as FP plot), and two things can happen:

A. When Node B plans the data according to a queue priority, if the H-RNTI transported in the FP frame is a BCCH-specific RNTI, the data refers to the BCCH message signaling and, consequently, the Node B carries out a transmission of signaling data according to the power of HS-

SCCH, the power of HS-PDSCH and a fixed number of channel layout codes configured in a higher layer and ignores an RACH measurement result IE and, on the other hand, the H-RNTI for HS-SCCH encryption is the BCCH specific H-RNTI.

B. When Node B plans the data according to the queue priority, if the H-RNTI transported in the FP frame is not a BCCH-specific H-RNTI, the data includes signaling or CCCH, DCCH and DTCH data and, for Consequently, the Node B performs a TFRC selection according to a physical layer category 12 of hS-DSCH and an RACH measurement result IE (generally, an Ec / N0 relation of CPICH) in the FP frame containing the data on which an HS-SCCH cipher is based and carried out using the H-RNTI of the FP frame.

In this case, CPICH is the abbreviation of common pilot channel and Ec / N0 refers to a signal-to-noise ratio at the chip level.

7. If the UE already has assigned the dedicated H-RNTI, the UE supervises the HS-SCCH channel using the dedicated H-RNTI and the BCCH-specific H-RNTI, and if the reception is correct the UE starts receiving the data of HS-PDSCH according to the information transported in the HS-SCCH.

8. If the UE has not assigned the dedicated H-RNTI, the UE supervises the HS-SCCH using the common H-RNTI and the BCCH-specific H-RNTI, and if the reception is correct, the UE starts receiving the data HS-PDSCH according to the information transported in the HS-SCCH.

As seen from the previous description, in case 6B, since the Node B does not know the capacity category of the UE that implements the E-FACH reception in the current cell, the Node B can only carry out the selection TFRC based on the lowest capacity category of the UE (eg, lowest HS-DSCH physical layer category 12).

It should be noted that, taking a Universal Mobile Telecommunications System (UMTS), for example, the UE capacity category includes the HS-DSCH physical layer category or the enhanced dedicated channel physical layer category (E-DCH), and corresponds to a series of parameters of physical layer (PHY), mAc, radio link control (RLC) and packet data convergence protocol (PDCP). The HS-DSCH physical layer category defines the UE that supports HSDPA in the UMTS. This category corresponds to a series of parameters that include the maximum supported number of channel layout codes, the reception capacity in the minimum time intervals of continuous transmission (TTI), the number of data bits for the largest transmission block. of HS-DSCH in a single TTI, supported modulation modes and multiple inputs and multiple outputs (MIMO), adopted by Node B as reference in the HSDPA planning.

In a flat architecture, an E-Node B is used to replace the original RNC and the Node B. A corresponding module of the E-Node B (for example, a module corresponding to the original Node B) does not know the UE's capacity category either. the E-FACH status, so that a similar problem remains.

In view of the foregoing, in one embodiment of the present invention, a method of transmitting data in an E-FACH state is provided, as shown in the schematic view of FIG. 1. The procedure includes the following stages.

101, a radio transceiver receives information indicating the capacity category of a UE.

The radio transceiver may be a Node B or a corresponding module in an E-Node B in the flat architecture (ie, a functional module corresponding to the original Node B in E-Node B).

The capacity category of the UE can refer to a physical layer category of the UE, for example the HS-DSCH physical layer category or the E-DCH physical layer category of the UE. The information indicating the capacity category of the UE can be a data or signaling frame, for example an HS-DSCH data frame indicating the UE capacity category, or signaling that contains the UE capacity category, or signaling indicating the UE capability category, for example a signaling that instructs the radio transceiver to store the UE capacity category when the UE passes from the CELL_DCH state to the CELL_FACH state.

Depending on the different information indicated by the UE capacity category, the radio transceiver can acquire the UE capacity category from explicit or implicit information. Explicit information refers to information that directly contains the capacity category of the Ue, for example the HS-DSCH data frame or signaling, for example signaling of part of application of Node B (NBAP), which contains the capacity category of the EU. The implicit information refers to information that does not directly contain the UE capacity category, but indirectly allows the radio transceiver to acquire the UE capacity category.

When the radio transceiver is specifically a related module in E-Node B, an RNC entity and a Node B entity are integrated into E-Node B, but the internal mechanism of E-Node B continues to function according to the functions specific to the RNC and Node B.

102, the radio transceiver acquires the category of capacity of the UE according to the information that indicates the category of capacity of the UE.

The radio transceiver acquires the EU capacity category in different ways depending on the different information indicated by the EU capacity category.

When the information is explicit, the radio transceiver directly solves the information to acquire the UE capacity category.

When the information is implicit, the information does not directly contain the EU capacity category, but indirectly allows the radio transceiver to acquire the EU capacity category. It is assumed that the radio transceiver is a Node B and, for example, when the UE is about to carry out a transition between RRC connection states, the RNC initiates an NBAP signaling indicating that the UE passes from the CELL_DCH state to the CELL_FACH status. Since the Node B has already stored the UE capacity category locally when the UE is in the CELL_DCH state, the related NBAP signaling (e.g., the radio link erasure request signaling) sent by the RNC to the Node B instructs Node B to store (not erase) the UE capacity category. Therefore, in the E-FACH state, the Node B carries out a data transmission according to the category of stored capacity of the UE, that is, the NBAP signaling implicitly indicates the corresponding UE capacity category in the Node B Therefore, the radio transceiver acquires the capacity category stored locally from the UE.

103, the radio transceiver carries out a data transmission according to the capacity category of the UE.

Specifically, the radio transceiver carries out the TFRC selection according to the UE capacity category to implement the data transmission accordingly.

The following describes multiple modes of information that indicate the capacity category of the UE.

Mode 1: An HS-DSCH data frame (eg, HS-DSCH data frame TYPE2) is used to carry an indicator of a HS-DSCH physical layer category of a UE, eg a mobile station (MS).

For a better understanding, the format of the data frame TYPE2 of data frame HS-DSCH is then taken as an example, which is compared with the format of the data frame of TYPE2 of HS-DSCH data frame defined in the 3GPP R7 protocol above in the following illustration.

FIG. 2 shows an example of the data frame format of the HS-DSCH data frame TYPE2 according to an embodiment of the present invention. For ease of description, the "data frame of TYPE2 of HS-DSCH data frame" is represented below as the "FP frame". The difference of the FP frame is in the definition of a fourth octet of the FP frame, which is illustrated below.

The fourth octet of the FP frame of the previous R7 protocol includes two parts, namely an FACH indicator IE (FI) and a spare part, while in the embodiment of the present invention, the fourth octet of the frame FP includes three parts, namely an FI IE, an HS-DSCH category IE and a reservation part. On the other hand, the FI IE definitions and the bit lengths of the two FP frames are also different, as shown in Table 1:

In the embodiment of the present invention, a new HS-DSCH category IE is defined in the FP frame, which is configured to indicate the HS-DSCH physical layer category of a target UE of a data frame of signaling. The HS-DSCH category IE has 4 bits in its entirety. When the FI IE is "11", the HS-DSCH category IE is filled with bits corresponding to the HS-DSCH physical layer category defined in the 3GPP R7 25.306 protocol, the corresponding relationship between them being shown below in Table 2; otherwise, the HS-DSCH category IE is populated with "0000", which is equal to the octet reservation part.

The reservation part in the fourth octet of the frame FP defined in the embodiment of the present invention has another 2 bits that can be filled with "00", and the two 2 bits can also serve as reservation and extension bit positions. for the HS-DSCH physical layer category of the succeeding UE.

It should be noted that the definitions in the two foregoing tables are offered by way of example only and do not limit the embodiment of the present invention. For example, the correlation between the HS-DSCH physical layer category defined in 25.306 and the HS-DSCH category IE of the FP frame in the embodiment of the present invention may not follow the specifications of Table 2, but having other modifications, which will not be described in the present document, and other similar modifications will be readily conceived by those skilled in the art.

Therefore, in this embodiment, in the E-FACH state, after obtaining the data frame of TYPE2 of the HS-DSCH data frame containing the HS-DSCH physical layer category of the UE, the Node B resolves the data frame to obtain the UE capacity category (ie the HS-DSCH physical layer category), performs data planning according to an E-FACH data transmission mode as defined in the protocol of the 3GPP R7 standard and transmits data in the corresponding channels.

Mode 2: The EU capacity category is included explicitly or implicitly in a signaling. Specifically, the signaling can be a NBAP signaling.

1) In the explicit case, the radio transceiver obtains an NBAP signaling that contains a physical layer category of the UE, resolves the signaling to obtain a UE capacity category, carries out a data planning according to a transmission mode of the UE. E-FACH data as defined in the protocol of the 3GPP R7 standard and transmits data in the corresponding channels.

2) An implicit case usually occurs in case of a transition between connection states. For example, when the UE passes from a CELL_DCH state to a CELL_FACH state, the RNC sends to the Node B an NBAP signaling containing a radio link erase request. The signaling initially aims to clear the original radio link parameter information (i.e., the radio link parameter information in the CELL_DCH state) of the UE to reconfigure the radio link parameter information in the CELL_FACH state of the radio. Node B. However, in the CELL_DCH state, the radio link parameter information stored in the Node B contains the physical layer category of the UE, so that in the embodiment of the present invention, when the UE passes. from the CELL_DCH state to the CELL_FACH state, the NBAP signaling sent from the RNC to the Node B instructs the Node B to store the physical layer category of the UE to allow the Node B to acquire the UE capacity category in the E-FACH state. In addition, the NBAP signaling may further include other HS-DSCH parameter configurations in the original CELL_DCH state to allow the UE, in the CELL_FACH state, to obtain a higher HS-DSCH transmission rate as much as possible. The following is a specific example of the NBAP signaling for a better understanding.

Taking, for example, the radio link clearing request signaling in the NBAP signaling, when the UE passes from the CELL_DCH state to the CELL_FACH state, the RNC sends the radio link clearing request signal to the Node B to clear parameters related radio links in the CELL_DCH state.

In this embodiment, in order to allow the Node B to acquire the UE capacity category, a transition indicator of the RRC states of the UE in the current link erase is added to the link clearing request signaling. radio. The RRC state transition indicator is defined in Table 3 as follows:

Table 3

 State transition information RRC

         '

 > RRC state transition indicator

 O Enumerated (CELL_FACH)

 OR WHOLE (0 ... 65535)

In Table 3, an RRC state to which the UE corresponding to the radio link erased by the RRC state transition indicator IE is about to enter includes an inactive state and a CELL_FACH state, and the transition indicator indicator IE. RRC states can be extended.

The HS-DSCH-RNTI IE instructs the RNC to allocate a new H-RNTI to the UE corresponding to the deleted radio link.

After the Node B receives the RRC state transition information IE, if the RRC state transition indicator IE indicates the CELL_FACH status and the RNC assigns a new H-RNTI to the UE, the transition indicator IE RRC states contain an HS-DSCH-RNTI IE, so that the H-RNTI stored in Node B corresponds to the H-RNTI stored in the UE, and Node B stores a corresponding relationship between the physical layer category of HS-DSCH and the H-RNTI of the UE corresponding to the radio link. The RRC state transition indicator Ie may also include other HS-DSCH parameter configurations in the original CELL_DCH state. These parameters may include if the modulation mode of quadrature amplitude 64 (64-QAM) and mode parameters, MIMO mode and mode parameters, CQI finally notified by the UE, etc., is supported, so that Node B You can use the corresponding capacity category of the UE and the previous HS-DSCH parameters to reference when carrying out the TFRC selection to carry out the corresponding data transmission.

It should be noted that the Node B can only store a part of or the other HS-DSCH parameters in the original CELL_DCH state, or it can only store the physical layer category information or store all the information.

If Node B stores the physical layer category information of the UE in the link clearing according to the NBAP signaling, this amounts to implicitly sending an indicator of the UE capacity category, via the RNC, to the Node B through NBAP signaling.

In case the radio transceiver is a corresponding module of the E-Node B, the RNC entity and the Node B entity are integrated in the E-Node B, so that the data frame, the NBAP signaling, etc. ., transmitted between the RNC and the Node B are internal transmission signals in the E-Node B. Therefore, according to manufacturers' specific designs, the data frame or the NBAP signaling may be used to transmit the layer category information. of the UE between the RNC entity and the Node B entity within the E-Node B, or a data transmission format defined in the E-Node B can be used to transmit the UE physical layer category information between the RNC entity and the Node B entity.

As described above, in the method of transmitting data in the E-FACH state according to the embodiment of the present invention, since the indicator of the UE capacity category is explicitly or implicitly sent to the Node B , when the UE receives E-FACH data in the CELL_FACH state, the Node B carries out the TFRC selection in CCCH, DCCH and DTCH data queues of the RNC based on the HS-DSCH physical layer category of the target UE, instead of the lowest physical layer category (eg, category 12), thus increasing the speed of data transmission in the E-FACH state. In the technical solution of the flat architecture embodiment, a similar technical effect can be achieved using the corresponding technical solution, which will not be described again in the present document.

Correspondingly, as shown in FIG. 3, in one embodiment of the present invention a network system is also provided, and the system can operate in an E-FACH state. The system includes a control apparatus 10 and a radio transceiver 20. Specifically, the radio transceiver 20 can be a Node B, and the control apparatus 10 can be an RNC. Alternatively, the radio transceiver 20 can be a corresponding module (e.g., a transceiver module) in an E-Node B in the flat architecture, and the control apparatus 10 can be a corresponding module (e.g. control) in E-Node B in the flat architecture.

The control apparatus 10 includes an emission unit 100 configured to send to the radio transceiver 20 information indicating the capability category of a UE to command the radio transceiver to carry out a data transmission in an E-FACh state according to the EU capacity category. The UE capability category includes a HS-DSCH physical layer category or an EU E-DCH physical layer category.

In order to send different information indicating the capacity category of the UE, the broadcast unit 100 may include a first subunit of broadcast 1000 or a second subunit of broadcast 1002 or a third subunit of broadcast 1004.

The first broadcast subunit 1000 is configured to send an HS-DSCH data frame containing the UE capacity category to the radio transceiver.

The second emitting subunit 1002 is configured to send to the radio transceiver a first signaling containing the UE capacity category.

The third emission subunit 1004 is configured to send a second signaling to the radio transceiver indicating the UE capacity category. The signaling includes an indicator that informs the radio transceiver that it has to store the UE capacity category when the UE moves from a CELL_DCH state to a CELL_FACH state.

The emission unit 100 may include any one or more of the three previous subunits, and FIG. 4 shows a case in which all three subunits are present.

The format of the HS-DSCH data frame can adopt the format of the FP frame in the embodiment of the present invention, as shown in FIG. 2 as an example. That is, the fourth octet of the FP frame contains both the FI IE and the HS-DSCH category IE to jointly indicate the UE capability category.

The FI IE indicates whether the UE is in the CELL_FACH state and whether the H-RNTI, an RACH measurement result and a HS-DSCH physical layer category of the UE are provided, as can be seen in Table 1.

The HS-DSCH category IE indicates the HS-DSCH physical layer category of the target UE of the data frame, that is, the UE capacity category. Specifically, when the FI IE indicates that the

HS-DSCH physical layer category of the UE, the HS-DSCH category IE can provide the specific capacity category of the UE according to the HS-DSCH physical layer category defined in the 3GPP R7 protocol 25.306; and when the FI IE indicates that the HS-DSCH physical layer category of the UE is not provided, the HS-DSCH category IE is populated with a 0 octet, as shown in Table 2.

The above description about the format of the HS-DSCH data frame is only provided by way of example, and the HS-DSCH data frame of the present invention may have other formats. For example, the EU capacity category can be included in other octets of the data frame, and the EU capacity category indicator can be implemented in other ways, without necessarily having a length of 6 octets in total, and not describes again in this document.

The first signaling may be an NBAP signaling, and the specific NBAP signaling adopted to notify the radio transceiver of the related UE capability category is apparent to those skilled in the art, so that the details are not offered again in This document.

The second signaling may be an NBAP signaling, which may specifically be an NBAP signaling containing a radio link erase request that is sent from the RNC to the Node B during the transition of connection states, for example when the UE passes the state CELL_DCH to the CELL_FACH state. A transition indicator of the RRC states of the UE in the current link deletion as shown in Table 3 is added to the signaling. The RRC state transition indicator of the UE carries two information elements:

1. RRC state transition indicator information, indicating an RRC state to which the corresponding UE is about to enter.

2. HS-DSCH-RNTI information, which is included when the RRC state transition indicator information indicates that the UE is about to enter the CELL_FACH state, and the information instructs the RNC to allocate a new H-RNTI to the corresponding UE.

After the Node B receives the RRC state transition indicator from the UE, if the RRC state transition indicator information indicates that the UE is about to enter the CELL_FACH state, the RRC state transition indicator IE it also contains an HS-DSCH-RNTI IE, so that the H-RNTI stored in Node B corresponds to the H-RNTI stored in the UE, and the Node B stores a corresponding relationship between the physical layer category of HS- DSCH and the H-RNTI of the UE corresponding to the radio link. The RRC state transition indicator IE may also include other HS-DSCH parameter configurations in the original CELL_DCH state.

As described above, when the radio transceiver 20 is a corresponding module (eg, a transceiver module) of the E-Node B, the rNc entity and the Node B entity are integrated into the E-Node B, of So that the data frame, the NBAP signaling, etc., transmitted between the RNC and the Node B are internal transmission signals in the E-Node B. Therefore, according to specific designs of the manufacturers, the data frame can be used. or the NBAP signaling for transmitting the UE physical layer category information between the RNC entity and the Node B entity within the E-Node B, or a data transmission format defined in the E-Node B can be used for transmit the UE's physical layer category information between the RNC entity and the Node B entity.

Correspondingly, referring to FIG. 5, the radio transceiver 20 includes a reception unit 200, a acquisition unit 202 and a transmission processing unit 204. The reception unit 200 is configured to receive information indicating the capacity category of a UE. The acquisition unit 202 is configured to acquire the capacity category of the UE according to the information indicating the category of capacity of the UE received by the reception unit 200. The transmission processing unit 204 is configured to carry out the transmission of data in an E-FACH status according to an indicator of the EU capacity category.

Corresponding to the sending unit of the control apparatus 10, the receiving unit 200 includes a first receiving sub-unit, a second receiving sub-unit or a third receiving sub-unit.

The first reception sub-unit is configured to receive a HS-DSCH data frame indicating the UE capacity category and, correspondingly, the acquisition unit 202 resolves the HS-DSCH data frame to acquire the HS-DSCH data category. EU capacity.

The second reception sub-unit is configured to receive a first signaling indicating the UE capacity category, where the first signaling contains the UE capacity category and, correspondingly, the acquisition unit 202 resolves the first signaling to acquire the EU capacity category.

The third reception sub-unit is configured to receive a second signaling indicating the UE capability category, where the signaling includes an indicator informing the radio transceiver 20 that it has to store the UE capacity category when the UE passes from a CELL_DCH state to a CELL_FACH state. Correspondingly, the acquisition unit 202 resolves the second signaling, stores the capacity category of the UE in the CELL_DCH state during the transition of states according to the result of the resolution and acquires the locally stored capacity category of the UE.

In the example of the second signaling in the control apparatus 10 according to the embodiment of the present invention, if the second signaling includes a transient indicator LE of the RRC states of the UE, the acquisition unit 202 resolves the IE to acquire a new H-RNTI assigned by the RNC to the UE, so that the acquisition unit 202 stores a corresponding relationship between the HS-DSCH physical layer category and the H-RNTI of the UE corresponding to the radio link.

Correspondingly, the transmission processing unit can carry out a data transmission in the E-FACH state according to the capacity category of the UE acquired by the acquisition unit.

The definitions of the HS-DSCH data frame and the NBAP signaling in the above devices are consistent with the definitions of the control apparatus 10 according to the embodiment of the present invention.

As described above, in the system according to the embodiment of the present invention, since the RNC explicitly or implicitly sends the indicator of the capacity category of the UE to Node B, when the UE receives E-FACH data in the CELL_FACH state, the Node B carries out the TFRC selection in CCCH, DCCH and DTCH data queues of the RNC based on the HS-DSCH physical layer category of the target UE, instead of the category 12, thus increasing the speed of data transmission in the E-FACH state.
