BACKGROUND

Universal Mobile Telecommunications System (UMTS) is the Third Generation Partnership Project (3GPP) is responsible for promoting and marked Potential of the third generation mobile communication system including a core network, radio access network and user equipment (UE) Other subsystems. Wherein, UMTS radio access network (UTRAN) is shown in Figure 1, wherein A Node B (Node B) comprises one or more cells, Node B and the radio network controller (RNC) interface between the Iub interface, RNC and the RNC interface between the Iur interface, RNC And the core network interface Iu interface. RNC and Node B it controls form a wireless network subsystem System (RNS), UE via the Uu interface that is connected to the wireless air interface and the UTRAN, the Uu interface in Figure 1 is not shown.

The UTRAN Iub and Iur interface control plane and user plane into two parts, one controlled Built plane corresponding to Node B Application Part (NBAP) protocol and the Radio Network Subsystem Application Part (RNSAP) protocol; user plane is a data frame (FP) protocols, including the framing protocol and a dedicated channel Common channel frame protocol for transmission between the RNC and Node B of the user plane data packet.

The radio air interface (Uu interface), and high-speed downlink packet access (HSDPA) related The protocol is mainly related to the physical layer, media access control (MAC) layer and the corresponding RRC System (RRC) layer. Shown in Figure 2, RRC layer includes an idle mode and connected mode two basic Mode of operation, wherein the connection pattern further comprises a cell dedicated channel state (CELL_DCH), small Area status Forward Access Channel (CELL_FACH), the cell paging channel state (CELL_PCH) And user registration area paging channel state (URA_PCH) of four seed state. By controlling RNC The UE RRC connection different migration between sub-state, to achieve efficient use of radio resources. For example, When the UE needs to transmit large amounts of data, the UE may use the HSDPA in CELL_DCH state And high-speed uplink packet access (HSUPA) to achieve high-speed data transmission; fewer measures of the UE According to the need to be transmitted, can enter CELL_FACH state, through the upstream direction, carrying the material Processing a random access channel (PRACH) of the random access channel (RACH), and downlink Fangxiang Cheng Contained in the auxiliary common control physical channel (S-CCPCH) on the forward access channel (FACH) to transmit Data; while when the UE has no data to transmit, then the RRC connection into the other sub-state, Thereby reducing the occupancy of the radio resources. ...

Specifically, UE at each transmission time interval (TTI), and by listening to the HS-SCCH Determine the HS-PDSCH corresponding TTI data carried by the channel whether their own data. Its The, HS-SCCH includes information carrier 16 bit high-speed downlink shared channel radio network temporary Identifier (H-RNTI). UE is based on the H-RNTI to determine the TTI corresponding HS-PDSCH channel Whether carried by their own data.

HSDPA in the original agreement can only be used CELL_DCH state, but in updating the relevant agreements In order to enhance the CELL_FACH state the UE data transmission capacity, reduce UE from CELL_FACH state to the CELL_DCH state transition delay, 3GPP HSDPA extended to the CELL_FACH state.

The UE in CELL_FACH state, still using the HSDPA transmission channel HS-PDSCH, Still using the downlink control channel HS-SCCH, UE based on the HS-SCCH carries the H-RNTI to judge Off the TTI corresponding HS-PDSCH channel if data needs to have their own reception. However, CELL_DCH state and the HSDPA transmission type, CELL_FACH state HSDPA In the upstream direction transmission is no longer used HS-DPCCH channel feedback CQI and ACK / NACK information, Instead of using other ways to achieve the link adaptation.

PCH is mapped to by the HS-PDSCH channel, the HS-PDSCH required for paging UE, The HS-PDSCH channel used for voice or data communications can be achieved without a UE in HS-PDSCH And S-CCPCH channels are switched frequently to monitor the paging channel messages and data, thereby reducing the switching Extension and UE power. In addition, the S-CCPCH saved channel code word and the used power is available In other transmission, can significantly improve system capacity and throughput.

Here, in a CELL_DCH state the UE, the less the amount of data into the CELL_FACH state, FACH is not mapped to a conventional S-CCPCH channel, but the mapping The HS-PDSCH channel, the process known as HS-FACH.

In the existing protocols, the realization of CELL-FACH includes two processes, one is the UE belongs The base station is always in service RNC (SRNC), within the jurisdiction provide no adjacent RNC Services; other UE is roaming to the adjacent first cell under the RNC.

A first process of implementation shown in Figure 3, including:

1) RNC RRC module of the physical channel reconfiguration (Physical Channel Reconfiguration) message to the UE into CELL_FACH state;

2) UE in RRC module to release resources, through the physical channel reconfiguration complete (Physical Channel Reconfiguration Complete) message response RNC, RNC its notification In which the state of the resource area;

3) RNC via a wireless connection delete request (Radio Link Deletion Request) message through Know NodeB release resources;

4) NodeB release resources and through a wireless connection delete response (Radio Link Deletion Request Response) message response RNC requests;

5) RNC and NodeB released between transport bearer for the UE to establish;

6) When the RNC found transmit downlink data to the UE, through the FACH transport bearer, The data to be transmitted after the transmission to the packing process NodeB;

7) NodeB from FACH transport bearer packets received by the S-CCPCH carrying the entire Broadcast on a cell, UE resolution S-CCPCH data on the identification information of the UE according to hair it is judged Give their own information, and then deal with it accordingly.

Through this process descriptions that current technology can not support the proposal by the UE CELL_DCH state to HS-FACH state, which is due to:

1, UE and the RNC in the process of interaction (eg RRC establishment process), RNC known to Whether the UE supports HS-FACH function, while the subordinate base stations each cell whether to support the HS-FACH power Able, through the current scenario there is no way to get. If the RNC does not support the requested UE in a HS-FACH cell functions transferred to the HS-FACH state, the UE will result HS-FACH state Can not receive data;

2, when in the HS-FACH state the UE roams to a new RNC subordinate cell, If the cell site does not support HS-FACH state, in the HS-FACH state UE while still However, the HS-PDSCH data is received will result in failure to receive data;

3, if the UE supports the cell an HS-FACH, the aforementioned step 7) can know the current User data is transmitted through a common channel from the channel establishment process (Common Transport Channel Setup) to create a transport bearer to NodeB transmission, and NodeB receives from the transport bearer The data directly in the S-CCPCH transmitted, resulting in a HS-FACH state UE No Be able to receive the data.

CELL-FACH for the aforementioned second implementation, the process is shown in Figure 4, including:

1) in the HS-FACH state the UE detects a new entry into the cell, and reads the system wide Broadcast information to know how the new cell in the HS-PDSCH for downstream data;

2) UE PRACH physical channel through the common control channel (CCCH) hosted on L3 Message added to the drift RNC (DRNC); L3 message contains the UE identifier message, update the cell Cause and other information;

3) DRNC via uplink signal transmission indication (Uplink Signalling Transfer Indication) Message the UE upload L3 message, and other relevant information, such as notifications such RNTI SRNC;

4) SRNC parse out the bearer of L3 message and make the appropriate treatment, the response L3 consumption Information transmission request signal via the downstream (Downlink Signalling Transfer Request) message To DRNC; here, SRNC according to UE still support HS-FACH, decide whether Send data on the HS-DSCH;

5) DRNC L3 message will be sent by the S-CCPCH to the UE.

As can be seen from the above description, the current technology implementation does not support the HS-FACH Initial UE RNC into the adjacent cell treatment because:

1, SRNC DRNC currently do not know whether to support the HS-FACH feature. SRNC from The DRNC reported Uplink Signalling Transfer Indication message in the S-RNTI may be Get UE is in the HS-FACH state, which requires a cell under DRNC from HS-FACH L3 message issued state, and if at this time the UE accesses the cell does not support the HS-FACH function will HS-FACH state resulting UE failed to receive data;

2, DRNC receives Downlink Signalling Transfer Request message, is currently Through established S-CCPCH send data up and down, rather than up and down from the HS-DSCH send data, Resulting HS-FACH state is still a UE failed to receive data.

In summary, both the UE is SRNC range, or into the DRNC range, the current Technical solutions are unable to accurately achieve in CELL_DCH state UE, enter CELL_FACH State, FACH is not mapped to a conventional S-CCPCH channel, but mapped to the HS-PDSCH Channel, i.e. by the HS-PDSCH channel to receive data.

Example one:

Figure 5 is one embodiment of the invention the UE is in CELL_DCH state into the HS-FACH State of a flow chart, the method is applied when the UE is the SRNC, includes the following steps:

Step 501, NodeB and RNC to the restart NodeB resource state is notified, the small District capability set reporting, and the establishment of a common transport channel.

NodeB reboot, you need to re-state their own resources, such as whether to support the HS-FACH state State and other information reported to the SRNC, thereby initiating the process, or do not know the NodeB SRNC the information Source state, in order to achieve the HS-FACH, it must initiate this process. The purpose of this step is to SRNC Informed NodeB supports HS-FACH, if supported, the establishment of public transport channels to the letter Transmission of data tracks, the common transport channel is a HS-PDSCH channel. Reported the cell where the UE can There are two ways to set force, the first method is used by the NodeB or SRNC initiates audit (Audit) Process, RNC NodeB in each cell that supports HS-FACH function and save it; Another is the process of resource status reporting, RNC in each cell that is supported NodeB HS-FACH function and save it. A first flow of the method shown in Figure 6, comprising the steps of: ...

NodeB reboot, you need to re-state their own resources, such as whether to support the HS-FACH state State and other information reported to the SRNC, thereby initiating the process, or do not know the NodeB SRNC the information Source state, in order to achieve the HS-FACH, it must initiate this process. The purpose of this step is to SRNC Informed NodeB supports HS-FACH, if supported, the establishment of public transport channels to the letter Transmission of data tracks, the common transport channel is a HS-PDSCH channel. Reported the cell where the UE can There are two ways to set force, the first method is used by the NodeB or SRNC initiates audit (Audit) Process, RNC NodeB in each cell that supports HS-FACH function and save it; Another is the process of resource status reporting, RNC in each cell that is supported NodeB HS-FACH function and save it. A first flow of the method shown in Figure 6, comprising the steps of: ...

2, RNC sends the audit request to the NodeB (Audit Request) message requesting NodeB Reported to the base station resource status.

3, NodeB through the audit response (Audit Response) message, the base station under the respective cells Resource status notification RNC.

In the first embodiment of the present invention, the expansion of the existing Audit Response message in the message Adds information element (IE), is used to indicate each of the base station and its subordinate local community, local small Block, whether to support the HS-FACH cell function, namely whether the support CELL_FACH state, the next Rows of data carried on the HS-PDSCH. Expanded, Audit Response message message format as shown in Table 1 below:

Information Element / information element Su-level name (IE / Group Name)	Existence (Presence)	Range (Range)	Information elements Type and reference Examination (IE Type and Reference )	Semantic description (Semantics Description)	Urgency (Criticality)	Emergency treatment Mode (Assigned Criticality)

Table 1

In the message format, community information, local community information and group information for the expansion of the local community within Content, respectively, district, local community and the local community group supports HS-FACH feature. In this One embodiment of the invention, these three IE extension must not exist in the message can only package Which contain one or two. Further, the information element type is the standard and reference index and chapters. Wherein the ability of the HS-FACH representing the set of two ways, namely, as shown in Table 2 and Table 3 below:

Information Element / Group name	Existence)	Range	Information element type and reference Test	Semantic description
					HS-FACH capability sets			Enumeration (support)	Indicate whether they support the UE CELL_FACH state, the number of downstream It is mapped to the HS-DSCH Add Lose.

Table 2

Information Element / Group name	Existence	Range	Information element type and reference	Semantic description
					HS-FACH capability sets			Enumeration (not to support)	Indicate whether they support the UE CELL_FACH state downlink data Mapped on HS-DSCH transmission.

Table 3

The difference between these two structures is that the manner shown in Table 2, there is only the IE, indicating Supporting the CELL_FACH state the UE is mapped to the downlink data transmitted on the HS-DSCH, there is no Indicates not support; the approach is shown in Table 3, respectively, with a different value that indicates whether the UE supports CELL_FACH state, the downlink data are mapped on HS-DSCH transmission.

RNC receives the Audit Response in the news, but also for the following treatment:

4, RNC receives the Audit Response message parsing the base station and / or the base station under the various A local community, and / or local community groups, and / or whether to support the HS-FACH cell function.

5, if the relevant IE have expressed support for the feature, then the base station and / or the local community Groups and / or the cell and / or the ability to set the local community is set to be used; if you do not support, or the Audit Response message does not contain instructions related to IE, then that the local cell and / or a local community group And / or cell function does not support the HS-FACH.

Through this process, RNC to the NodeB informed of the base station / the local community / the local community Group / The cell capability set. And the second base station supports the obtained function HS-FACH method comprising The following steps:

1, when the base station needs to report the resource status to the RNC, the transmission resource status indication (Resource Status Indication) message to the RNC. Also requires the existing Resource Status Indication Extended message in the message indicates an increase IE base station and / or the individual local cell and / or a local cell Groups and / or community supports HS-FACH feature. Specific extensions such as shown in Table 4:

Information element / class name information element	Existence	Information element type and reference	Urgency	Emergency treatment

Table 4

As can be seen from Table 2, the Resource Status Indication message expansion mode and Audit Response message is the same, but also the expansion of base stations, community information, local community information and local Cell group information, respectively, base stations, district, local community and supports local community groups HS-FACH functions. Similarly, these four extended IE must not exist in the message can only Containing one or more of them.

2, RNC receives the Resource Status Indication message parsing the base station / all local Community / Local community groups / community supports HS-FACH feature.

3, if the relevant IE expressed support for the feature, then the the base station / each local community / local Cell group / community capability set is set to be used; if you do not support, or the Resource Status Indication message does not contain instructions related to IE, then consider that the base station / each local community / local Cell group / community does not support the HS-FACH feature.

Above audit processes and resources are able to achieve status reporting process to obtain NodeB RNC Cell capability set, informed whether to support HS-FACH function, these two methods are executed, but also Can perform only one of them.

Then, also established between the RNC and NodeB common transmission channel for transmission to HS-FACH state the UE downlink data. Because when the RNC informed his subordinates in a small NodeB Region in the UE into HS-FACH state, and between the RNC and NodeB does not provide for CELL_FACH state UE HS-DSCH transmission of data transport bearer establishment, you must RNC And NodeB establish a correlation between the transport bearer. Specific implementations there are two different ways, first One way is to CELL_FACH each for the HS-PDSCH transmission is the establishment of specialized Transport bearer to achieve,

The first way:

The process is shown in Figure 7, comprising the following steps:

1, RNC NBAP message via common transmission channel establishment request (Common Transport Channel Setup Request) message to inform the NodeB, the message that the establishment for the transmission UE in CELL_FACH state data of the HS-PDSCH channel number, each channel in related public Total transmission channel ID, using a specific HS-FACH H-RNTI, used to establish the transport bearer binding ID, transmission bearer address, the transport network layer QoS and other parameters. Which HS-FACH H-RNTI may Assigned by the system so the common H-RNTI, it can be a UE of the original CELL_DCH state Body assigned RNTI. The common H-RNTI refers to a group of HS-PDSCH assigned to a common Identity.

Among them, the need for Common Transport Channel Setup Request message can be extended Extended message format shown in Table 5:

Information Element / Group Name	Existence	Range	Information elements Type and reference Test	Semantic description	Importance	Emergency treatment Mode
							Message Description	M		9.2.1.45		-

Table 7

The extended Common Transport Channel Setup Response message adds HS_FACH information IE, including the establishment of a common transmission channel's ID, binding ID, and transmission Layer address information.

3, is established between the RNC and NodeB each HS-PDSCH associated transport bearer.

Through the above process, established for the HS-PDSCH for each bearer required for the transfer, but Establishment of public transport channel is not permanently maintain the RNC detects when the cell does not exist HS-PDSCH transmitted using the downlink data CELL_FACH state of UE, or the use of a particular H-RNTI identifies a group of UE, the need to remove the corresponding common transmission channel. The removal process mining With existing protocols implemented by the process shown in Figure 8, comprising the steps of:

1, RNC in a common transmission channel deletion request (Common Transport Channel Deletion Request) message indicating the need to delete the corresponding HS-FACH common transport channel ID, the ID is the process of establishing the channel assignment, and the message notification NodeB;

2, NodeB make provision for the use of public transport to delete channel deletion response (Common Transport Channel Deletion Response) message response RNC requirements;

3, RNC receives the response message, then release the transport bearer.

When it is necessary to establish the HS-PDSCH transmission bearer reconfiguration, for example, to reconfigure Set transmission bearer QoS, you can initiate public transport channel reconfiguration procedure. The process shown in Figure 9 Shown, comprising the steps of:

1, RNC in public transport channel reconfiguration request (Common Transport Channel Reconfiguration Request) message indicating the need to re-configure the corresponding common HS-FACH Transmission channel ID and the corresponding transport network layer quality of service (TNL QoS), and may be reallocated The HS-FACH H-RNTI, and the message notification NodeB.

In this step, you need to modify existing agreements Common Transport Channel Reconfiguration Request message, in which the increase reconfigurable HS-PDSCH transmission bearer QoS requirements, the modified message format shown in Table 8:

Table 8

In the message the same extensions as HS_FACH information IE, expressed the need for reconfiguration HS-FACH H-RNTI and the transport network layer bearer QoS.

2, NodeB receives the Common Transport Channel Reconfiguration Request extinction Interest rates, heavy with transmission bearer QoS, NBAP message with public transport channel reconfiguration response (Common Transport Channel Reconfiguration Response) message response to the RNC Requirements.

The second way:

This method is to create a plurality of H-RNTI corresponding to the HS-PDSCH shared by a transport bearer, Its difference with the first method in that: The first way is for each HS-PDSCH transmission are built Establish a dedicated transport bearer to achieve, and the second way is for multiple H-RNTI corresponding HS-PDSCH create a shared one transport bearer. In the second mode, simply modify the way a The expanded Common Transport Channel Setup Request message, the message H-RNTI H-RNTI group replaced, modified, with a H-RNTI identifies the group H-RNTI, With the H-RNTI indicates that the group index for the relationship with the UE.

Table 9

In the second mode, the plurality of the UE on the HS-PDSCH using the same data transmission bearer A H-RNTI, thus, also the structure of the data to be modified FP frame to identify the data frame Belongs UE, wherein the structure of the existing FP frame shown in Figure 10, the specific modification method is to Shared the frame reservation (Spare Extensio) bits of the H-RNTI corresponding increase index, indicating that the FP data frames transmitted corresponding H-RNTI, that is, the H-RNTI for which UE.

The common transmission channel is established, its process of deleting and re-configuration of the first way The same is not repeated herein.

Step 502, a UE in CELL_DCH state of less because downlink data thus transferred to the CELL_FACH state. RNC according to step 501 to obtain cell capability set and saved UE Capability set, determining the RNC, that is, into the HS-FACH state SRNC.

Step 503 - step 504, SRNC and the UE through a physical channel between reconfiguration (Physical Channel Reconfiguration) release Uu mouth DCH resources, including the possibility of HS-DSCH Resources, DCH resources, enhanced DCH (E-DCH) resources and indicating that the UE enters HS-FACH State, and distribution of the UE in this state H-RNTI.

Step 505 - step 507, RNC and NodeB removed through a wireless connection between the (Radio Link Deletion) process, the release CELL_DCH related resources, including possible HS-DSCH resources, DCH resource, E-DCH resources and the corresponding transport bearer. After release, the codeword corresponding to the resources And power can be recovered.

In this case, if the RNC found in the cell, the UE is not allocated for the HS-FACH H-RNTI to establish the appropriate transport bearer, or previous creation fails, step 501 will be launched in the public Total transmission channel establishment process, for the establishment of appropriate transport bearer.

Step 508, when the RNC has sent in the HS-FACH state data in the UE, through the Transport bearer will be established in advance HS-PDSCH data frames sent under the NodeB.

Step 509, NodeB from the HS-FACH transport bearer issued the data received on the data mapping HS-PDSCH added onto lost UE.

Via step 501 to step 509 of method used to achieve a UE in CELL_DCH state Transfer HS-FACH state, but the method is executed on the premise that the cell does not occur roaming UE, always In the same cell range. But the UE can not always be in the same cell, destined to roam To another cell within the case, we must use the method described below, to achieve the UE HS-FACH State.

First, when in the HS-FACH state is already in the UE roams to a new cell, and The cell with the previous cell is attributed to the same in the SRNC, the UE is faced with two different treatment Cases: one is that the new cell supports HS-FACH function, the other is the new cell does not support HS-FACH functions.

Support for new cell function HS-FACH case, the use of method shown in Figure 11 at the HS-FACH state the UE roams to SRNC HS-FACH support under the new cell function Data transmission, comprising the steps of:

Step 1101, in HS-FACH state subordinate SRNC UE roams to a new district, Through a broadcast channel (BCH) on the broadcast system information, that the district supports HS-FACH function;

Step 1102, UE SRNC via RACH channel to transmit cell update (Cell Update) Message redirection required cell and the HS-PDSCH receiving a response message;

If the cell is not appropriate for the HS-FACH transport bearer establishment, then in step 501 The process of establishing common transport channels, to establish the appropriate transmission between SRNC and NodeB bearer;

Step 1103, SRNC via HS-PDSCH corresponding response message to the cell update confirmation (Cell Update Confirm) message to the UE.

In one embodiment of the invention, since each NodeB at boot time to go through the step 501 The method will be reported to the RNC cell capability set and saved, so SRNC has been informed of the new small Area supports the HS-FACH, so to avoid the prior art, RNC does not know whether the new cell Support HS-FACH, resulting in the new cell does not support data channel issued. Performing step 901 To 903, SRNC can be directly on the HS-PDSCH of the downlink data transmission to the UE.

The cell does not support the new HS-FACH function case, the use of method shown in Figure 12 HS-FACH state in the UE roams to the SRNC does not support the function of HS-FACH new Cell data transmission, comprising the steps of:

Step 1201, in HS-FACH state UE roams to a new cell SRNC subordinates, Through the system information broadcast on the BCH that the cell does not support the HS-FACH function;

Step 1202, UE through the RACH channel sent to the RNC Cell Update message requesting small Redirection area, and in the S-CCPCH to receive a response message;

Step 1203, RNC to the UE receives the uploaded Cell Update message, according to the known small District capability set that the HS-FACH state UE new access cell function is not supported HS-FACH, Then transferred to the UE in CELL_FACH state tradition, and through the S-CCPCH of the corresponding response Cell Update Confirm message is sent to the UE.

In addition to the above two methods, there is an alternative way to achieve the state in the HS-FACH The UE roams to a cell under the SRNC process shown in Figure 13, comprising the steps of:

Step 1301, in HS-FACH state UE roams to a new cell SRNC subordinates, Through the BCH system information broadcast on the cell that the cell capability sets;

Step 1302, regardless of whether the cell supports HS-FACH function, UE through the RACH channel Road to the RNC sends Cell Update message requesting cell redirection, and received on the S-CCPCH Response message;

Step 1303, RNC to the UE receives the uploaded Cell Update message, according to the known small District capability set that the HS-FACH state whether the UE supports new access cell HS-FACH power Energy, whether or not supported, are transferred to the UE in CELL_FACH state tradition, and through The corresponding S-CCPCH Cell Update Confirm message is sent in response to the UE.

UE receives the Cell Update Confirm message into traditional CELL_FACH state.

Example two:

This embodiment is in the HS-FACH state of the UE in the adjacent cell in the RNC receives data to achieve Process. When the HS-FACH state is already in the UE roams to a new cell, and the cell is Attributable to the adjacent RNC, i.e. DRNC, the UE is also faced with two different treatment situations: First Species are the cell function supports HS-FACH, the other is that the cell does not support the HS-FACH functions.

In the first case, the processing shown in Figure 14, including:

Step 1401, in HS-FACH state UE roams to a new cell DRNC subordinates, Through the BCH system information broadcast on the cell that supports HS-FACH feature.

Step 1402, UE through the RACH channel to the DRNC sends Cell Update message requesting Cell redirection and HS-PDSCH receive a response message, which may be another layer 3 (L3) messages, and is not limited to Cell Update message.

Step 1403, DRNC receives the Cell Update message, the message is carried through a U-RNTI Flag is judged that the UE belongs to another RNC, RNSAP message will be constructed so DRNC uplink signal Transmission indication (Uplink Signalling Transfer Indication) message, the cell in the message Capacity Capacity (Cell Capability Container FDD) IE indicated that the cell is to support the DRNC HS-FACH support function, in which the L3 Information IE included in the received port elimination Uu Interest.

This embodiment requires Uplink Signalling Transfer Indication message to be extended, in Add the message the UE belongs DRNC cell supports the HS-PDSCH based on enhanced CELL_FACH capability indication by Cell Capability Container FDD IE increased DRNC in the description of the cell capability set to implement this feature. Expanded the message as shown in Table 10:

Step 1404, SRNC receives Uplink Signalling Transfer Indication message, Which parses the L3 message and proceed accordingly. In Cell Update for example, SRNC determines that UE belongs to HS-FACH state, and currently resides community support HS-FACH feature, so constructed Response message Cell Update Confirm, and included in the downstream signaling messages please RNSAP Find (Downlink Signalling Transfer Request) message transmitted DRNC.

This embodiment also requires Downlink Signalling Transfer Request message to be extended, Increase in the message carried by L3 message is issued via S-CCPCH or through the HS-PDSCH Issued. Extended message format shown in Table 12:

Information elements / information element group name	Existence	Range	Information elements Type and reference Test	Semantic description	Importance	Specified output Square error handling Formula
							Message type	M		9.2.1.40		YES	Ignore

Table 13

Step 1405, as in this embodiment to support the new cell function HS-FACH, DRNC analysis The Downlink Signalling Transfer Request message L3 message, by mapping to HS-PDSCH transmitted on the FACH channel to the UE.

For the second case, that the new cell does not support HS-FACH features, solutions, shown in Figure 15 Shown, comprising the steps of:

Step 1501, in HS-FACH state UE roams to a new cell DRNC subordinates, Through the system information broadcast on the BCH that the cell does not support the HS-FACH function;

Step 1502, UE through the RACH channel to the DRNC sends Cell Update message requesting Cell redirection, and S-CCPCH to receive a response message;

Step 1503, DRNC receives the L3 message Cell Update after the message carried by the U-RNTI of the UE determines flag belongs to another RNC, RNSAP message will be constructed so DRNC Uplink Signalling Transfer Indication, in the message of the Cell Capability Container FDD IE in the cell indicates that the RNC does not support the HS-FACH function, in which the L3 Information IE included in the received message Uu mouth;

Step 1504, SRNC receives Uplink Signalling Transfer Indication message from To resolve the L3 message and proceed accordingly to Cell Update for example, SRNC determines the UE Belongs to HS-FACH state, and currently resides does not support HS-FACH cell function, so constructed Response message Cell Update Confirm, and include it in the message Downlink RNSAP Signalling Transfer Request message passed DRNC, indicating that the UE into ordinary CELL_FACH state;

Step 1505, DRNC parse out Downlink Signalling Transfer Request message The L3 message, and maps to the S-CCPCH transmitted on the FACH channel to the UE. UE receives The response message, turn ordinary CELL_FACH state.

In addition to the above two methods, there is an alternative method to achieve HS-FACH state UE roaming Under the RNC to the adjacent cell receiving data, the method is both new cell core supports HS-FACH function, UE are directly converted into traditional CELL-FACH state. This method processes such as Figure 16, comprising:

Step 1601, in HS-FACH state UE roams to a new cell DRNC subordinates, Through the BCH system information broadcast on the ability of the cell that set;

Step 1602, regardless of whether the cell supports HS-FACH function, UE via RACH channel Send to RNC Cell Update message requesting cell redirection, and received on the S-CCPCH ring Should message;

Step 1603, DRNC receives the L3 message Cell Update after the U-RNTI by carrying Flag is judged that the UE belongs to another RNC, therefore, DRNC RNSAP message will be constructed Uplink Signalling Transfer Indication;

Step 1604, SRNC receives Uplink Signalling Transfer Indication message from To resolve the L3 message and proceed accordingly to Cell Update, for example, will construct the response message Cell Update Confirm, and the response message is included in the RNSAP message Downlink Signalling Transfer Request message passed DRNC, and instructed the UE into ordinary CELL_FACH state;

Step 1605, DRNC parse out Downlink Signalling Transfer Request message The L3 message, and maps to the S-CCPCH transmitted on the FACH channel to the UE. UE receives The response message, turn ordinary CELL_FACH state.
