Description

Method, device and system for improving number of online users of packet service

Technical field

The present invention relates to the field of network communication technologies, and in particular, to a method, device and system for increasing the number of online users of a packet service.

Background of the invention

At the 3GPP RAN29 meeting, a work item for Continuous connectivity for packet data users was approved, and the goal of the work project is to increase the number of online users of the group service.

The source of the work item is: For some services, the business flow model is intermittently sent by data. In a business process, the number of data interruptions is very large, such as web browsing services, generally downloading web pages and browsing web pages. Alternate, that is, there is data transmission and no data transmission alternately. Some services require long-term sporadic data transmission. If there is no data transmission, they will maintain the same state. Allocating resources without data transmission will waste resources. If the connection is established at the beginning of data transmission, it will be released at the end of the data transmission. The connection will result in frequent establishment and release of the connection, increase the load of the system control, and increase the data transmission delay.

In response to the above problems, the permanent online work project hopes to use a certain technology to enable the UE. (User Equipment) to maintain the CELL-DCH state (connected state) for a long time in the idle time when there is no data transmission. At the same time, it consumes less resources.

In the existing WCDMA (Wideband Code Division Multiple Access) protocol, when the UE is in the CELL-DCH state, the uplink DPCCH (Dedicated Physical Control Channel) must transmit a signal, which causes uplink interference to other users, so that The number of users in the connected state is limited.

Therefore, in 3GPP TR 25.903 V0.0.3 disclosed in 3GPP in October 2005, two schemes of DPCCH gating and DIR target reduction are proposed to solve the above problem.

Referring to FIG. 1, the DPCCH gating scheme periodically transmits an uplink control channel only in a partial subframe of a partial frame when the data is in an inactive state, and normally transmits an uplink control channel in a data transmission state. This method can increase the number of users without data transmission in the cell. This solution can also improve the capacity of HSPA (High Speed Packet Access) when carrying IMS (Integrated Multimedia Subsystem) real-time services.

However, due to the discontinuous transmission of uplink data, the scheme has the following drawbacks:

1) The power control of the downlink F-DPCH (slice dedicated physical channel) channel will be affected by the uplink discontinuous transmission;

2) The channel estimation process during uplink demodulation is affected. In order to achieve the same out-of-synchronization detection of the physical layer, it is required to use a higher transmission power when transmitting the DPCCH, which limits the degree of performance improvement. The SIR target reduction scheme is specifically as follows: When there is no data transmission on the uplink, the base station actively reduces the SIR target, so that the transmit power of the DPCCH is reduced to the extent that the inner loop power control can be maintained, and the uplink CQI (channel quality indication) is turned off. .

In the above SIR Target reduction scheme, since the uplink DPCCH is still transmitted continuously, although the required DPCCH power is reduced, the improved uplink capacity is still limited.

During the specified time, the network side including the HSPA user service cell detects that the HSPA user has no valid data for high-speed uplink and downlink, and the HSDPA (High-Speed Downlink Packet Access) queue is empty, and the E-DPCCH (Enhanced Dedicated Physical Control Channel) When no valid signal is detected on the network, the network side notifies the UE through the HS-SCCH (High Speed Shared Control Channel) signaling, and enters the HSPA inactive state. After receiving the HS-SCCH signaling, the UE passes the HS-DPCCH. (High-speed dedicated physical control channel) ACK (acknowledgement response) The response network side indicates the confirmation of the HSPA inactive state, and the terminal side where the UE is located and the network side where the network side is located enter the inactive state; E-DCH (Enhanced Dedicated Channel) demodulation resources are free for other users to facilitate hardware resource management, making E-DCH AG (absolute authorization) 0 or INACTIVE (inactive);

In the HSPA inactive state, the uplink and downlink stop transmitting signals of all dedicated channels;

In the HSPA inactive state, the UE stops transmitting the uplink DPCCH, the E-DPCCH, the E-DPDCH (enhanced dedicated physical data channel), the HS-DPCCH, and the like, and the UE records the final transmit power;

At the same time, the downlink corresponding to the UE also stops transmitting all signals, including F-DPCH (Slice-Specific Physical Channel), and the network side records the final downlink transmit power and CQI;

In the inactive state of HSPA, the power control recovery operation is performed, so that the transmission power of the terminal and the network side meets the channel ratio of the receiving end, so that when the data transmission is resumed, the time of data transmission recovery can be shortened;

The power control recovery operation includes -

1) The UE detects the strength of the downlink pilot signal in real time. When it detects that the downlink pilot signal strength changes beyond the specified range, it immediately resumes the normal uplink data transmission, starts transmitting the signal of the DPCCH channel, and the network side detects the DPCCH signal sent by the UE. , the transmission of the F-DPCH signal is resumed, and the UE detects the F-DPCH signal sent by the network side, and then switches to the HSPA activation state; or

2) The UE detects the strength of the downlink pilot signal in real time. When detecting that the downlink pilot signal strength changes beyond the specified range, it immediately resumes normal uplink data transmission, starts transmitting the signal of the DPCCH channel, and transmits the signal to the network through the E-DPCCH channel. The side application sends data, and the special E-TFCI code in the E-DPCCH signal, such as all 0s, synchronizes with the network side, and after receiving the E-DPCCH signal, the network side resumes the downlink data transmission, and confirms on the E-HICH. After the UE correctly receives the E-HICH signal, it switches to the HSPA activation state; or,

Resume the transmission of the uplink DPCCH signal, and the network side detects the DPCCH signal sent by the UE, and the shell [J switch To the HSPA activation state; or,

4) In the HSPA inactive state, if the time of maintaining the inactive state exceeds the predetermined threshold, the network side immediately resumes normal downlink data transmission, starts transmitting the signal of the F-DPCH channel, and notifies the UE through HS-SCCH signaling. After the downlink data is sent, the UE resumes the transmission of the uplink DPCCH signal after receiving the HS-SCCH signaling, and the acknowledgment information is received by the HS-DPCCH channel, and the network side receives the acknowledgment information on the HS-DPCCH channel, and then switches to the HSPA activation. status.

5) In the HSPA inactive state, if the time of maintaining the inactive state exceeds the predetermined threshold, the UE immediately resumes the normal uplink data transmission, starts transmitting the signal of the DPCCH channel, and the network side immediately resumes the normal downlink data transmission, and starts. After transmitting the signal of the F-DPCH channel, the UE and the network side stop transmitting the signal after maintaining the signal for transmitting the predetermined time, and return to the HSPA inactive state.

In this process, the slow power control mode is adopted for both the uplink and the downlink, for example, the power control frequency is 500 Hz or 300 Hz;

In this power control recovery process, the multipath search window position on the network side can be updated, and the CQI information can also be updated;

In the HSPA inactive state, the out-of-synchronization detection of the link is performed;

The specific out-of-step detection process includes:

1) When there is data to be sent in the downlink, if the feedback of the UE is not received at the specified time, it is determined that the UE has lost the step, and the link is initiated by the network side;

2) When there is data to be sent on the uplink, if the feedback from the network side is not received at the specified time, the UE may determine that the local end has lost synchronization, initiate a cell update report through the RACH channel, and the network side receives the cell update reported by the UE. Initiating link release after reporting;

3) When the UE initiates the power control recovery process, if the network side feedback is not received at the specified time, the UE may determine that the local end has lost synchronization, initiate a cell update report through the random access channel RACH channel, and receive the UE by the network side. The link release is initiated after the reported cell update report is sent;

4) When the network side initiates the power control recovery process, if the UE does not receive feedback from the UE for a certain period of time, it is considered that the UE is out of synchronization, and the network side initiates the link release;

In the HSPA inactive state, when data transmission is detected, the HSPA active state is entered;

When the network side detects that there is data in the HSDPA queue to be transmitted, it immediately resumes normal downlink data transmission, turns on the downlink transmitter, starts transmitting the signal of the F-DPCH channel, and the UE detects the signal of the F-DPCH channel, then turns on the uplink transmission. Recovering the transmission of the uplink DPCCH signal, and detecting the DPCCH signal sent by the UE on the network side, completing the process of switching from the HSPA inactive state to the HSPA activation state; Or, when the network side detects that there is data in the HSDPA queue to be sent, immediately resumes normal downlink data transmission, turns on the downlink transmitter, starts transmitting the signal of the F-DPCH channel, and notifies the UE that the downlink data exists through the HS-SCCH signaling. To send. After receiving the HS-SCCH signaling, the UE slams the uplink transmitter, resumes the transmission of the uplink DPCCH signal, and feeds back the acknowledgment information through the HS-DPCCH channel, and the network side receives the acknowledgment information on the HS-DPCCH channel, and the completion is completed. The process of switching the HSPA inactive state to the HSPA active state.

The initial transmit power PDPCCH after UE activation is: the transmit power PDPCCH last recorded by the UE when entering the HSPA inactive state, plus the change amount ARTWP of the total bandwidth power RTWP received during the UE resume transmission from the UE entering the HSPA inactive state, In addition, the ACPICH RSCP, that is, the PDCPCH = PDPCCH last +ARTWP + ACPICH RSCP; or PDPCCH = PDPCCH last +ARTWP + ACPICH RSCP;

The initial transmit power of the UE after activation is PDPCCH: It is calculated according to the principle of open-loop power control, and the calculation method is the same as the initial establishment of the link.

When the UE detects that there is data in the HSUPA queue to be sent, immediately resumes normal uplink data transmission, turns on the uplink transmitter, starts transmitting the signal of the DPCCH channel, and the network side detects the DPCCH signal sent by the UE, then turns on the downlink transmitter and resumes F. - Transmission of the DPCH signal, the UE detects the F-DPCH signal transmitted by the network side, and completes the process of switching from the HSPA inactive state to the HSPA active state.

Alternatively, when the UE detects that data is to be sent in the HSUPA queue, the normal uplink data transmission is resumed immediately, the uplink transmitter is turned on, the signal of the DPCCH channel is started, and the data is sent to the network side through the E-DPCCH channel, and the network side After receiving the E-DPCCH signal, the downlink transmitter is turned on to resume downlink data transmission, and it is confirmed on the E-HICH that after the UE correctly receives the E-HICH signal, the handover from the HSPA inactive state to the HSPA activation state is completed. the process of.

The initial transmit power PF-DPCH on the network side is: the transmit power PF-DPCH last recorded on the network side when entering the HSPA inactive state, plus the power offset configuration parameter Apower, ie PF-DPCH = PF-DPCH last + Apower, or , a fixed power set according to the common channel coverage requirement, configured by high-level signaling;

When a state transition between an active state and an inactive state occurs, if the activation set includes a plurality of network side links, the HSPA activation state switching process is performed;

In the soft handover state, because the out-of-synchronization detection of the physical layer cannot be performed in the HSPA inactive state, the handover information between the HSPA inactive state and the HSPA activation state needs to be notified from the network side where the HSPA serving cell is located to the HSPA non-time in time. The network side where the serving cell is located. This process is implemented by controlling the FP (Frame Protocol), as shown in Figure 2: In the soft handover state, if the active set includes multiple network side links, when the state of the UE is switched between the HSPA active state and the HSPA inactive state, the network side of the active set including the HSPA serving cell switches the state. The information is sent to the RNC (Radio Network Control) through the uplink control FP. After receiving the uplink control FP, the RNC distributes the information of the state switching to the network side of the other HSPA non-serving cells in the active set to complete the state switching. The state is the HSPA inactive state. The network side of the HSPA non-serving cell stops detecting the out-of-synchronization of the link set and disables the transmission of the downlink F-DPCH. Alternatively, after the RNC receives the uplink control FP, according to the current state of the UE, The same out-of-synchronization report reported by the network side of the HSPA non-serving cell is processed. Only when the current state of the UE is the active state, and the network side of the HSPA non-serving cell reports the radio link out-of-synchronization report, the radio link may be determined to be out of synchronization.

The operations in the above-mentioned HSPA inactive state include: power control recovery operation, link out-of-synchronization detection, data transmission detection and the like are performed in parallel.
