Description

Sending data to the user equipment to achieve a method, system and device

Technology

The present invention relates to wireless communication technologies, particularly to achieve the user device sends data, system Systems and equipment.

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. ...

At the physical layer, HSDPA downlink physical channels include two, one is used for carrying user data Offers high-speed physical downlink shared channel (HS-PDSCH), the other is used to carry along with the number of demodulating Data channel HS-PDSCH high-speed shared control channel signaling required (HS-SCCH). HSDPA in Increases in the direction of a high-speed uplink dedicated physical control channel (HS-DPCCH), which channel is used to order Feedback data frames containing downlink HS-PDSCH is (ACK) No (NACK) signal is received correctly Interest, or for a feedback channel quality indicator (CQI).

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 , It is proposed in the paging CELL_PCH and URA_PCH state UE, HS-PDSCH is also used Channel instead of using the conventional S-CCPCH channels. PCH is mapped to by the HS-PDSCH , In the HS-PDSCH required for paging UE, the HS-PDSCH channel used for voice or data The UE can not communicate in HS-PDSCH channel and S-CCPCH channel to listen for frequent switching Paging messages and data, thereby reducing switching delay and the UE power. In addition, the S-CCPCH savings Channel codeword used for HSPA and power transmission, can significantly improve the system capacity and throughput Rate.

Here, the in CELL_PCH / URA_PCH state UE, its paging still pass Achieved over HS-PDSCH, or PCH is mapped to the HS-PDSCH, and not mapped to a conventional The S-CCPCH, and the process known as HS-PCH.

In the existing protocol, to achieve in CELL_PCH / URA_PCH state UE paging Includes two processes, one is the home base station UE is always in service RNC (SRNC) jurisdiction Range, no adjacent RNC to provide services; other UE is roaming to the adjacent first RNC Subordinate district.

A first implementation of the process shown in Figure 3, when a UE is in CELL_DCH state holding Continued small amount of data, it will shift to the CELL_FACH state, if the data volume is further reduced, Will be transferred from the CELL_FACH state CELL_PCH or URA_PCH state, then UE From the S-CCPCH to receive paging data, when SRNC cell under the right decision in CELL_PCH or URA_PCH state when paging a UE, first by the SRNC and the Plots created PCH transport bearer will contain information related to PCH paging data frames transmitted to NodeB; NodeB according to the received PCH is mapped to the information broadcast on S-CCPCH.

In this implementation, does not accurately achieve HS-PCH, on the one hand because of the current SRNC I do not know whether the cell under the HS-PDSCH based on the support paging, if the NodeB or cell Does not support this feature, you paging failure; hand, PCH data frames through the SRNC with NodeB common transport channel between the process of establishing a transport bearer establishment transmission, although SRNC Wish to use the HS-PDSCH is mapped to way paging, but can not recognize the transmission NodeB PCH data frames carrying on the map to which physical channel.

Another implementation of the process shown in Figure 4, the HS-PCH state in the UE into the adjacent RNC, ie the drift RNC (DRNC) under the district, and through the cell update (Cell Update) Notification procedure where SRNC their current cell location; SRNC determines the RNC in the adjacent cell In the UE paging, RNSAP protocol based paging request (Paging Request) elimination Message will notify paging parameters required DRNC; DRNC SRNC according to the order, structure Paging Message and mapped to the broadcast on the S-CCPCH, the UE in order to achieve paging.

In this implementation, the same can not be accurately achieved HS-PCH, because at CELL_PCH / URA_PCH state and the downlink transport channel is mapped to the HS-PDSCH transmission The UE roams to the neighboring RNC, DRNC not the UE status information is not known to the UE paging message is mapped to the HS-PDSCH channel is the conventional S-CCPCH channel. If you then DRNC down from the S-CCPCH message, while UE is in prison on HS-PDSCH Listen to the information they need, will result in loss of information.

Through the above description, regardless of the scope of UE is SRNC, or into the DRNC Fan Wai, current technology solutions are unable to achieve an accurate HS-PCH, that is, into CELL_PCH / URA_PCH state UE, PCH data frame is not mapped to a conventional S-CCPCH Channel, but is mapped to HS-PDSCH channel, i.e. the channel via HS-PDSCH to receive data Purposes.

Furthermore, in addition, the updated protocol, the introduction of many new technologies, such as the downlink HSDPA was introduced in 64 quadrature amplitude modulation (QAM), the introduction of the uplink HSUPA channel The 16QAM, etc., through which the air interface technology to improve data throughput UE. However, the moment when the UE roams to a neighboring RNC when, SRNC DRNC cell does not know whether to support these new features, Then if required DRNC SRNC to provide their services and can not force, it will result in the DRNC Create a link failure.

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 the local community group supports HS-PCH Function, and to further expand the support for HSUPA16QAM and HSDPA64QAM situation. With Sample, these four extensions IE and support for HSUPA16QAM and HSDPA64QAM not Must exist in the message can contain only one or more of them.

2, RNC receives the Resource Status Indication message parsing the base station and / or the base Station under each cell and / or the local cell and / or the local cell supports the HS-PCH group functions to And support for HSUPA16QAM and HSDPA64QAM situation.

3, if the relevant IE expressed support for the feature, then the base station and / or the base station under various Cell and / or the local community and / or the ability to set local community group set and save the information available; if Not supported or that Resource Status Indication message does not contain relevant instructions IE, is recognized For the base station and / or under the base of each cell and / or the local cell and / or the local cell group does not support HS-PCH function, and save the information.

Above audit process and resource status reporting process are able to achieve access to the NodeB RNC Community capability set, informed whether to support HS-PCH functions, and for HSUPA16QAM and HSDPA64QAM support case. These two methods can both perform, you can only perform one Months.

Then, also established between the RNC and NodeB common transport channels for transmission RNC HS-PCH state to the downlink data of the UE. Because when the RNC informed his subordinates in a NodeB The UE enters the cell HS-PCH state, and between the RNC and NodeB and the UE does not HS-PDSCH transmission of data to create a transport bearer must be established between the RNC and NodeB phase Related transport bearer. Specific implementations in two different ways, the first way is to use each one CELL_PCH or URA_PCH in the HS-PDSCH transmission are built specifically to transport bearer Implementation,

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 CELL_PCH or URA_PCH state UE HS-PDSCH data in the number of channels, each A common channel associated transmission channel ID, the particular HS-PCH H-RNTI, for establishing transmission Bearer binding ID, transfer bearer address, the transport network layer QoS and other parameters. Which HS-PCH H-RNTI may be assigned by the system a common H-RNTI, the original UE itself can be allocated RNTI. The common H-RNTI refers to a set of HS-PDSCH receiving a paging message on the HS-PCH State UE assigned a public identity.

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

Table 5

Increases in the table information of the HS-PCH IE, to establish that the HS-PDSCH channel Public transport channel ID, using a specific HS-PCH H-RNTI, used to establish the transport bearer binding ID, transmission bearer address, the transport network layer QoS and other information.

2, NodeB make the establishment of public transport channel of preparation, public transport via NBAP message Channel establishment response (Common Transport Channel Setup Response) message response, the message In the establishment of the transport bearer to departure NodeB side of the information required.

Similarly, the Common Transport Channel Setup Response message also needs to be expanded Show, the extended message format as shown in Table 6:

Table 7

The extended Common Transport Channel Setup Response message adds HS_PCH information IE, including the establishment of a common transmission channel's ID, binding ID, and the transport layer Address and other information.

3, is established between the RNC and NodeB each HS-PCH-related transport bearer.

Through the above process, established for the HS-PCH for each bearer required for the transfer, but the establishment of Public transport channel is not permanently maintain, when RNC detects no longer exists in the cell using HS-PDSCH of the downlink data transmission state HS_PCH UE, or the use of a specific H-RNTI Identified a set of UE, you will need to delete the corresponding public transport channel. The removal process is the use of existing The protocol 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 remove the HS-PCH corresponding common transmission channel ID, which Is in 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-configured HS-PCH corresponding common pass Transport channel ID and the corresponding transport network layer quality of service (TNL QoS), and may be reassigned HS-PCH 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_PCH information IE, expressed the need for reconfiguration HS-PCH 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 of the correspondence between 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 Extension) bit in the H-RNTI corresponding increase index, indicating that the FP data frames transmitted corresponding H-RNTI, that is, the H-RNTI for which UE. Or in the frame Specifically add a field to indicate that the FP data frames transmitted corresponding to H-RNTI.

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_FACH state of less because downlink data to transfer Into CELL_PCH state. RNC according to step 501 to obtain cell capability set and saved UE Capability set, determining the RNC, that is, into the HS-PCH state SRNC.

Step 503 - step 504, SRNC and the UE through a physical channel between reconfiguration (Physical Channel Reconfiguration) Release Uu port FACH resources, and indicating that the UE enters HS-PCH state, and the UE is in this state, the H-RNTI.

Step 505 - step 507, RNC and NodeB removed through a wireless connection between the (Radio Link Deletion) process, CELL_FACH related resources released after the release of these resources corresponding Codeword and power can be recovered.

In this case, if the RNC found in the cell, the UE is not allocated for the HS-PCH 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 the HS-PCH state is sent to the data of UE, through the matter Transport bearer will be created under the data frame sent NodeB.

Step 509, NodeB from HS-PCH transport bearer issued data received on the data mapping Added to the HS-PDSCH lost UE.

Via step 501 to step 509 of method used to achieve a UE in CELL_FACH state Transfer HS-PCH state, but the method is executed on the premise that the cell does not occur roaming UE, always at In the same cell range. But the UE can not always be in the same cell, destined to roam The other cells within this time, we must use the method described below, to achieve the UE HS-PCH state State.

First, when in the HS-PCH state is already in the UE roams to a new cell, and the Compared with the previous cell is a cell attributed to the same in the SRNC, the UE is faced with two different treatment situation Condition: one is the support for the new HS-PCH cell function, and the other one is the new cell does not support HS-PCH functions.

Support for new cell HS-PCH function situation, using the method shown in Figure 11 implementation is HS-PCH state the UE roaming support SRNC features of the new HS-PCH data cell Transmission, comprising the steps of:

Step 1101, in HS-PCH state subordinate SRNC UE roams to a new district, Through a broadcast channel (BCH) on the broadcast system information, that the district supports HS-PCH 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 enabled for HS-PCH establish the appropriate transport bearer, 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-PCH, so to avoid the prior art, RNC does not know whether the new cell supporting Held HS-PCH, resulting in the new district issued an unsupported channel data. 1101 to perform the steps 1103, SRNC can notify the NodeB to the UE via HS-PDSCH of the downlink data transmission.

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

Step 1201, in HS-PCH 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-PCH 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-PCH state UE does not support the new access cell HS-PCH function, The UE into traditional CELL_PCH or URA_PCH state, and through the S-CCPCH to phase The response should be transmitted Cell Update Confirm message to the UE.

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

Step 1301, in HS-PCH 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-PCH function, UE through the RACH channel Send to RNC Cell Update message requesting cell redirection, and received on the S-CCPCH ring Should message;

Step 1303, RNC to the UE receives the uploaded Cell Update message, according to the known small District capability set that the HS-PCH state UE new access cell function is supported HS-PCH, Whether support is transferred to the UE traditional CELL_PCH or URA_PCH state, and By 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_PCH or URA_PCH state.

Example two:

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

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

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

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 carried by the user through Registration area wireless network temporary identifier (U-RNTI) flag determines that the UE belongs to another RNC, Therefore DRNC RNSAP messages will be constructed upstream signal transmission indication (Uplink Signalling Transfer Indication) message, in the message capacity of the cell capacity (Cell Capability Container FDD) IE indicated that the DRNC cell function is to support the HS-PCH, where The L3 information IE contains the received message Uu mouth.

This embodiment requires Uplink Signalling Transfer Indication message to be extended, in Messages are enhanced UE belongs DRNC cell function is supported HS-PCH's instructions, by Cell Capability Container FDD IE to increase the DRNC cell capability set to achieve a description of The function. Expanded the message as shown in Table 10:

Information elements / information element group name	Existence	Range	Information element class Type and reference	Semantic description	Importance	Specified output Square error handling Formula

IE nothing							Community capacity Capacity (Cell Capability Container FDD)	O	9.2.2.D	YES	Ignore
IE nothing							Community capacity Capacity (Cell Capability Container FDD)	O	9.2.2.D	YES	Ignore

Table 10

Wherein, for the existing Cell Capability Container FDD IE extended mainly to its First 15 bits are set for the support of HS-PCH function instructions. In this embodiment, the set When the SRNC detects that reported for the first 15 bit IE is 1, indicated that the cell support HS-PCH functions. Of course, in the specific application, and is not limited to 15 bits as the first, Use other bits that its essence is the same. Further, the present embodiment is also increased in IE The support for HSUPA16QAM and HSDPA64QAM case, respectively, with the first 19 bits and The first 20 bits indicate whether support HSDPA64QAM and HSUPA16QAM. The specific extended IE meanings shown in Table 11:

Information elements / information element group name	Exist Sex	Range	Information element class Type and reference	Semantic description

Each bit following meanings: First 1bit retained; Indicates whether the first 2bit support delay activation; Indicates whether the first 3bit support HS-DSCH; First 4bit retained; 5bit said first supports F-DPCH; 6bit said first supports E-DCH; 7bit said first supports E-DCH TTI2ms; 8bit that supports the first E-DCH 2sf2and2sf4 and the following capabilities; 9bit said first supports E-DCH 2sf2 and The following capabilities; 10bit indicates whether the first E-DCH 2sf4 support and Its following capabilities; First 11bit indicates whether its support for E-DCH sf4 The following capabilities; Said first supports 12bit E-DCH sf8 and The following capabilities; Indicates whether the first 13bit support E-DCH HARQ Redundant merger; Said first supports 14bit E-DCH HARQ Chase merger; Indicate whether the first 15bit support PCH mapped to HS-PDSCH or the CELL_PCH URA_PCH state, the previously described HS-FACH; Indicate whether the first 19bit support HSDPA64QAM; Indicate whether the first 20bit support HSUPA 16QAM. ...

Whether to support the specific features of each bit, the bit is 1:00 expressed support for the 0 indicates no support. Each bit following meanings: First 1bit retained; Indicates whether the first 2bit support delay activation; Indicates whether the first 3bit support HS-DSCH; First 4bit retained; 5bit said first supports F-DPCH; 6bit said first supports E-DCH; 7bit said first supports E-DCH TTI2ms; 8bit that supports the first E-DCH 2sf2and2sf4 and the following capabilities; 9bit said first supports E-DCH 2sf2 and The following capabilities; 10bit indicates whether the first E-DCH 2sf4 support and Its following capabilities; First 11bit indicates whether its support for E-DCH sf4 The following capabilities; Said first supports 12bit E-DCH sf8 and The following capabilities; Indicates whether the first 13bit support E-DCH HARQ Redundant merger; Said first supports 14bit E-DCH HARQ Chase merger; Indicate whether the first 15bit support PCH mapped to HS-PDSCH or the CELL_PCH URA_PCH state, the previously described HS-FACH; Indicate whether the first 19bit support HSDPA64QAM; Indicate whether the first 20bit support HSUPA 16QAM. ...

In the existing protocol, the first 15, 19 and 20 bits are reserved bits, the present embodiment of the invention for its expansion Exhibition, when the corresponding bit is 1, which means that supports the corresponding features otherwise not supported. Conversely also empathy.

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-PCH state, and currently resides community support HS-PCH function, so constructed ring Should message Cell Update Confirm, and the message contained in the downlink signal transfer request RNSAP (Downlink Signalling Transfer Request) message is passed to DRNC.

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.

Step 1406, when the SRNC determines the cell under the DRNC to page the UE when the RNSAP Paging Request message that is mapped to the PCH paging on HS-PDSCH.

This embodiment requires Paging Request message to be extended, indicating that the paging request is HS-PDSCH issued or issued through the S-CCPCH, expanded Paging Request message format Type shown in Table 12:

Information elements / information element group name	Existence	Range	Information element class Type and reference	Semantic description	Importance	Specified error Treatment
Information elements / information element group name	Existence	Range	Information element class Type and reference	Semantic description	Importance	Specified error Treatment	Message type	M	9.2.1.40	YES	Ignore
IE nothing							Message type	M	9.2.1.40	YES	Ignore
IE nothing							Paging channel mapping type (Paging Channel Mapped Type)	O	9.2.1. ^*	YES	Ignore

Table 12

Increases in the message type of mapping the paging channel IE, that the paging is HS-PDSCH Issued or issued by the S-CCPCH, or both by HS-PDSCH and the S-CCPCH Hair, specific instructions as shown in Table 13 below:

Information elements / information element group name Call	Existence	Range	Information element type and reference	Semantic description
Information elements / information element group name Call	Existence	Range	Information element type and reference	Semantic description	Paging Channel Mapped Type			Enumeration (HS-PDSCH, S-CCPCH, HS-PDSCH and the S-CCPCH)

Table 13

Step 1407, DRNC according to the SRNC instructions to the HS-PDSCH on the paging UE.

In the above process, UE can not perform cell redirection process, directly from the SRNC to the The UE initiates paging, that is, only steps 1406 and 1407.

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

Step 1501, in HS-PCH 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-PCH functions.

Step 1502, UE through the RACH channel to the DRNC sends Cell Update message requesting Cell redirection, and S-CCPCH to receive the 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-PCH function, in which the L3 Information IE included in the received message Uu mouth. For Uplink Signalling Transfer Indication same as the aforementioned extensions.

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-PCH state and district where the current does not support HS-PCH function, so constructed response Message Cell Update Confirm, and include it in the message Downlink Signalling RNSAP Transfer Request message passed DRNC, indicating that the UE into ordinary CELL_PCH or URA_PCH state.
