Abstract

Disclosed is a resource release method. A base station sends a first status indication or a second status indication to an RNC, the first status indication being used for indicating that a UE has released common enhanced-dedicated channel (common E-DCH) resources, and the second status indication being used for indicating that the UE needs to release the common enhanced-dedicated channel (common E-DCH) resources; and send a resource release instruction to the UE so as to cause the UE to release the common E-DCH resources. By means of the resource release method provided in embodiments of the present invention, downlink data loss caused by continuously scheduling downlink data from the UE by the RNC without knowing that the UE releases resources after the UE releases the resources is avoided; or, the RNC controls the UE to release resources, so that downlink data loss is avoided.

Description

Method, device and system for resource release technical field

The present invention relates to the field of communication technologies, and in particular to a method, device and system for releasing resources.

Background technique

There are five states of user equipment (UE) in Universal Mobile Telecommunications System (UMTS), namely: cell dedicated channel (CELL Dedicated Channel, CELL_DCH) state, cell forward access channel (CELL Forward Access Channel (CELL_FACH) state, Cell Paging Channel (CELL_PCH) state, UMTS Terrestrial Radio Access Network Registration Area Paging Channel (UMTS Terrestrial Radio Access Network Registration Area Paging Channel, URA_PCH) state and idle (idle) state, among them, CELL_PCH and URA_PCH can only send data when they are transferred to CELL_FACH state.

After the introduction of the enhanced CELL-PCH state, if the UE in the CELL_PCH state has a dedicated high-speed downlink shared channel wireless network temporary identifier H-RNTI (High-Speed Downlink Shared Channel Radio Network Temporary Identifier, HS-DSCH RNTI) and cell wireless network temporary Identification (Cell Radio Network Temporary Identifier, C-RNTI), then the UE can migrate to the CELL_FACH state, and directly send a measurement report (Measurement Report) to perform data transmission.

Since the UE in URA-PCH state will not notify the Radio Network Controller (RNC) after leaving a certain cell, and the dedicated RNTI is a cell-level identifier, after leaving a certain cell, it may communicate with another The RNTI allocated to a certain UE in a cell overlaps, which will cause a conflict, so the RNC cannot allocate an RNTI to a UE in the URA_PCH state. Therefore, if a UE in the URA_PCH state receives paging or has data to transmit, since there is no dedicated H-RNTI, it needs to transfer to the Cell_FACH state for data transmission, and the UE transfers from the URA_PCH state to the Cell_FACH state, and needs to first request the cell update from the RNC 1. After receiving confirmation from the RNC, the data transmission can only be performed after sending a reconfiguration completion message to the RNC. In this way, it can be completed through three signaling interactions, and the signaling overhead is relatively large, and the data transmission will cause a certain delay.

In the prior art, in order to save resources and reduce delay, a seamless migration technology for UEs in URA_PCH state is introduced (similar to enhanced CELL-PCH state, UEs in URA_PCH state only send one signaling to complete the process of migrating to CELL_FACH state), or called In order to enhance URA_PCH, the current scheme that supports seamless migration of UEs in URA_PCH state is:

Step 1: RNC broadcasts the mapping between common (common) Enhanced Dedicated Transport Channel (E-DCH) resources and dedicated identifiers, where the dedicated identifiers include C-RNTI (mandatory) and H-RNTI (optional) And Enhanced Dedicated Channel Radio Network Temporary Identifier (E-DCH Radio Network Temporary Identifier, E-RNTI) (optional).

Step 2: UE in URA_PCH state reads system information, selects a set of resources to initiate a random access process, and sends a measurement report, which is included in the Medium Access Control I Protocol Data Unit (MAC-I PDU) Carry U-RNTI for conflict resolution, because multiple UEs in enhanced URA_PCH state select the same set of resources to initiate random access in the same access slot may cause conflicts.

Step 3: The base station (NodeB) carries U-RNTI in the header of the Enhanced Media Access Control Protocol Data Unit (Medium Access Control ehs Protocol Data Unit, MAC-ehs PDU), and notifies the corresponding UE to pass the conflict resolution, and can use the corresponding resource.

The non-DCH state UE uses the common E-DCH resource broadcast in the system message, and after the use is completed, the resource needs to be released.

Currently, a UE with a dedicated RNTI will release resources after using common E-DCH resources. There are two ways of resource release: implicit resource release and explicit resource release. Implicit resource release process: After the UE finds that there is no data to be transmitted in the cache, or after reaching the maximum number of transmissions, it starts a timer configured on the network side (the timer can be configured as 0 or infinitely long, and when configured as infinitely long, then It is regarded as turning off the implicit release function), when the timer expires and the UE sends a buffer empty indication, it automatically releases resources and remains in the CELL_FACH state. Display release: The NodeB sends the E-AGCH channel with the value "inactive", and the UE will release the resource after receiving it. There are two ways of resource release, the NodeB can know whether the UE releases resources, but the RNC does not know.

Generally, if the network configures the UE to the CELL_FACH state, but does not configure RNTIs, the UE will initiate a CELL UPDATE process to request the network to configure relevant information.

After introducing the above-mentioned enhancements to the UE in the URA_PCH state in the prior art, the two resource release schemes are as follows:

One is: before the resources are released, the RNC will initiate a radio resource control (Radio Resource Control, RRC) reconfiguration process to configure a new RNTI for the UE, which requires multiple air interface signaling reconfigurations, and these RNTIs will be reconfigured after the UE releases resources. After the UE releases the resources, the NodeB will notify the RNC that the broadcast resources and identifiers will not change.

The other is: stipulate that the UE enters the CELL_FACH state after releasing the resource, and still use the RNTI obtained in the system message before. At this time, the NodeB needs to notify the RNC to change the identification information corresponding to the resource mentioned in the system message, because the information has been given to the UE. occupied.

In this way, in the two resource release schemes in the prior art, the RNC does not know when the UE releases the resources. It is possible that the RNC has not sent the RRC reconfiguration message to the UE, but the UE has released the resources, resulting in data loss.

detailed description

The embodiment of the present invention provides a method for resource release, which can prevent the RNC from continuously scheduling downlink data to the UE when the UE releases the resources, which may result in loss of downlink data. lose. The embodiment of the present invention also provides the corresponding base station, RNC, UE and system. Each will be described in detail below.

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

Referring to Fig. 1, an embodiment of a wireless network system provided by an embodiment of the present invention includes: a base station, an RNC, and a UE. The UE supports enhanced URA_PCH. The UE is originally in the URA_PCH state. After migrating to the Cell_FACH state, the public enhanced dedicated channel common E-DCH resources are used when sending data. After the data transmission is completed, the UE needs to release the common E-DCH resources to improve the utilization of common E-DCH resources. In the present invention In an embodiment, the UE may return to the URA_PCH state from the Cell_FACH state after the UE releases the E-DCH resource according to the pre-configuration with the RNC, or the RNC may pre-broadcast the corresponding indication in the system message or pre-configure the relevant indication to the UE, so that The UE returns to the URA_PCH state from the Cell_FACH state after releasing the E-DCH resource according to the indication.

Referring to FIG. 2, an embodiment of a method for resource release provided by an embodiment of the present invention includes:

S100. The UE sends a status report with SI=0, that is, the buffer status is "empty", to the base station. In the process of implicit resource release, the status report can be understood as a resource release request. The status report can be sent separately or included in the data MAC-i PDU.

SI=0 is sent separately, and indicates that the UE is ready to release resources during the implicit resource release process, that is, releases E-DCH resources when the RNC is unknown.

S105. The base station sends an ACK to the UE, that is, confirms receipt of the status report that the buffer state is "empty" sent by the UE, indicating that the UE is aware that the UE performs implicit resource release.

After receiving the status report of SI=0, the base station may also record the high-speed physical downlink shared channel radio network temporary identifier H-RNTI associated with the enhanced dedicated channel radio network temporary identifier E-RNTI used by the UE and the corresponding common E-DCH resources.

S110, the UE releases the E-DCH resource, and returns to the URA_PCH state from the Cell_FACH state.

S115. The base station sends a first state indication to the RNC, for example: URA_PCH state indication.

S120. The RNC schedules downlink data to the UE when the first state indication is not received, and when it is unknown that the UE has released the E-DCH resource.

S125. After the base station receives the downlink data scheduled for the UE, considering that the UE has released resources, directly discard the downlink data or record the corresponding data packet number, so as to notify the RNC of which data has not been successfully transmitted to the UE later, so as to facilitate the RNC to re-transmit Pass these data. That is: the base station does not schedule the downlink data to the UE.

Specifically, it may be: when receiving the downlink data scheduled by the RNC to the UE by using the H-RNTI, discarding the downlink data.

Before receiving the acknowledgment response, the base station rejects other UEs that support enhanced URA_PCH other than the UE that supports enhanced URA_PCH to compete for the same set of common E-DCH resources. The same set of common E-DCH resources is the support for the enhanced URA_PCH Resources used by the UE.

S130. After receiving the first state indication (URA_PCH state indication), the RNC learns that the UE has released the E-DCH resource, and sends an acknowledgment response to the base station.

After the RNC receives the first status indication, it will know that the UE has released resources, and if it still needs to schedule downlink data to the UE, it can schedule the UE downlink data through paging or directly, so that the UE can receive the data. In order to ensure the reliability of data transmission, NodeB can be required to add a timestamp to the state indication sent to RNC, for example: it can be a system frame number (System Frame Number, SFN), etc., to inform RNC at what time the UE is The resources are released, so that the RNC can know that the data scheduled after this point in time cannot be received by the UE, and the data can be retransmitted.

Optionally, if the UE has been assigned a dedicated H-RNTI or E-RNTI through reconfiguration signaling or other methods, the base station may only send the RNC Send the first status indication without receiving the confirmation response sent by the RNC, that is, step S130 is not required. At this time, after the base station receives the downlink data scheduled for the UE, according to the H-RNTI associated with the E-RNTI, the The data corresponding to the H-RNTI is discarded, while allowing other enhanced URA_PCH UEs other than the enhanced URA_PCH UE to compete for the same set of common E-DCH resource requests without waiting for the confirmation response sent by the RNC. Because the E-RNTIs or H-RNTIs used by these UEs are different at this time, different UEs can be distinguished by this.

Unlike the prior art where the RNC does not know when the UE will release resources, it is possible that the RNC has not canceled the RRC reconfiguration The information is sent to the UE, and the UE has released resources, resulting in data loss.

Moreover, in the embodiment of the present invention, the UE returns to the initial URA_PCH state after releasing resources. Compared with the prior art in which the UE stays in the CELL_FACH state after releasing resources, the UE cannot be returned to the initial URA_PCH state, and must be reconfigured through the air interface to achieve the goal, reducing the signaling of the UE returning to the URA_PCH state from the Cell_FACH state interact.

Referring to FIG. 3, another embodiment of the resource release method provided by the embodiment of the present invention includes:

S200. The RNC configures the information that the duration of the implicit resource release timer used by the UE supporting enhanced URA_PCH is infinite, or disables the UE's implicit resource release instruction.

RNC configures the timer for UE implicit resource release (that is, "E-DCH transmission continuation back off" enhanced dedicated information transmission continuation back off) to be infinite (infinity), and RNC needs to further instruct UEs in enhanced URA_PCH state to use this timer, You can add the value of "E-DCH transmission continuation back off for URA_PCH" to "infinity" in the system information, or turn off the indication that supports enhanced URA_PCH implicit release, or add the cell to support enhanced URA_PCH or support URA_PCH in the system information Indication of seamless transition. According to the indication, the UE determines that the network supports enhanced URA_PCH or URA_PCH seamless transition, and it can predetermine that if the enhanced URA_PCH or URA_PCH seamless transition process is used, the implicit release function will be disabled. In this way, other non-enhanced URA_PCH UEs (legacy UEs) will not be affected. These UEs of legacy UEs can still perform implicit resource release, but UEs that only need to support enhanced URA_PCH cannot perform implicit resource release.

S205. The UE sends a status report to the base station with SI=0, that is, the buffer status is "empty", indicating that the UE has no data to transmit. The status report can be sent separately or included in the data MAC-i PDU.

S210. The base station sends an ACK to the UE, that is, confirms receipt of a status report that the buffer status of the UE is "empty".

However, since the duration of the UE's implicit resource release timer is set to be infinite, the UE cannot perform implicit resource release.

Optionally, if the UE cache is not empty, the network side, such as the base station, may also decide to release the common E-DCH resources of the UE, and S205 and S210 may not occur at this time.

S215. The base station sends a second status indication to the RNC, where the second status indication is used to indicate the The UE needs to release common enhanced dedicated channel common E-DCH resources.

S220. The RNC sends an acknowledgment response to the base station.

The confirmation response may be an indication that the RNC instructs the base station to release the common E-DCH resources of the UE. The confirmation response may also carry configuration information for configuring the UE to enter other non-URA_PCH states after the resources are released.

S225. The base station sends a resource release instruction to the UE.

The resource release command can be a common E-DCH resource release command carried by the E-DCH absolute grant channel E-AGCH (EDCH-Absolute Grant Channel), that is, the information carried is "INACTIVE" and the absolute authorization range is "All HARQ processes" to release resources.

If the base station receives the confirmation response sent by the RNC and also includes configuration information indicating that the UE enters other states after resource release, the base station sends the information to the UE, and then sends a resource release instruction to the UE.

S230. The UE releases the E-DCH resources, and returns to the URA_PCH state from the Cell_FACH state after the resources are released.

If receiving configuration information from the base station indicating that the UE enters other states after resource release, the UE enters the indicated state after resource release.

In the resource release method provided by the embodiment of the present invention, the RNC controls the UE to release resources, thereby preventing the RNC from scheduling downlink data to the UE when the UE does not know that the UE releases resources, resulting in data loss. Compared with the prior art in which the UE stays in the CELL_FACH state after releasing resources, the UE cannot be returned to the initial URA_PCH state, and must be reconfigured through the air interface to achieve the goal, reducing the signaling of the UE returning to the URA_PCH state from the Cell_FACH state interact.

Referring to FIG. 4, another embodiment of the resource release method provided by the embodiment of the present invention includes:
