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 communications technologies, and in particular, to a method, device, and system for resource release.

Background technique

The User Equipment (UE) in the Universal Mobile Telecommunications System (UMTS) has five states: CELL Dedicated Channel (CELL_DCH) and 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 (URA_PCH) state and idle (idle) State, where CELL_PCH and URA_PCH can only send data when they go to the CELL_FACH state.

After the CELL-PCH state is introduced, the UE in the CELL_PCH state has a dedicated High-Speed Downlink Shared Channel Radio Network Temporary Identifier (HS-DSCH RNTI) and a temporary radio network. If the Cell Radio Network Temporary Identifier (C-RNTI) is used, the UE can migrate to the CELL_FACH state and directly send a measurement report (Measurement Report) to perform data transmission.

The UE in the URA-PCH state does 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 be different from the other. The RNTIs allocated to a certain UE in a cell coincide, and thus a collision occurs, so the RNC cannot allocate the RNTI to the UE in the URA_PCH state. Therefore, if the UE in the URA_PCH state receives the paging or has data to transmit, since there is no dedicated H-RNTI, it needs to go to the Cell_FACH state to perform data transmission. The UE is transferred from the URA_PCH state to the Cell_FACH state, and the cell update needs to be requested from the RNC first. After the acknowledgment by the RNC, the data transmission can be performed after the reconfiguration complete message is sent to the RNC, so that the signaling can be completed through three signaling interactions, and the signaling overhead is 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 technique of the URA_PCH state UE is introduced (similar to the enhanced CELL-PCH state, and the URA_PCH state UE only sends one signaling to complete the migration to the CELL_FACH state), or To enhance URA_PCH, the current scheme for supporting seamless migration of URA_PCH UEs is:

The first step: the RNC broadcasts a common enhanced Dedicated Transport Channel (E-DCH) resource and a dedicated identifier mapping, where the dedicated identifier includes C-RNTI (required), H-RNTI (optional) And an E-DCH Radio Network Temporary Identifier (E-RNTI) (optional).

The second step: the URA_PCH state UE reads the system message, selects a set of resources to initiate a random access procedure, and sends a measurement report, which is in the Medium Access Control I Protocol Data Unit (MAC-I PDU). Carrying the U-RNTI for collision resolution, because multiple enhanced URA_PCH state UEs selecting the same set of resources to initiate random access in the same access slot may cause collision.

The third step: the base station (NodeB) carries the U-RNTI in the header of the Medium Access Control ehs Protocol Data Unit (MAC-ehs PDU), and notifies the corresponding UE to resolve the conflict, and can use the corresponding Resources.

The non-DCH state UE uses the common E-DCH resource broadcasted in the system message, and needs to release the resource after the usage is completed.

Currently, a UE with a dedicated RNTI will release resources after using the common E-DCH resource. There are two ways to release the resource: implicit resource release and display resource release. Implicit resource release process: After the UE finds that there is no data in the buffer to be transmitted, or reaches the maximum number of transmissions, it starts a timer configured on the network side (the timer can be configured as 0 or infinitely long. When configured to be infinitely long, It is considered to be the implicit release function. When the timer expires and the UE sends a buffer to the empty indication, the resource is automatically released and remains in the CELL_FACH state. Display release: The NodeB contains the value of "inactive" by sending the E-AGCH channel, and the UE releases the resource after receiving it. In the manner in which the two resources are released, the NodeB can know whether the UE releases the resource, and the RNC does not know.

Generally, if the network configures the UE to the CELL_FACH state but does not configure the RNTIs, the UE initiates the CELL UPDATE procedure to request network configuration related information.

After the enhancement of the URA_PCH state UE in the above prior art is introduced, the two resource release schemes are respectively:

One is: before the resource is released, the RNC initiates a radio resource control (RRC) reconfiguration process, and configures a new RNTI for the UE, which requires multiple air interface signaling reconfigurations, and these RNTIs release the resources after the UE releases the resources. After the UE releases the resources, the NodeB notifies the RNC to broadcast the resources and identifiers.

The other is that the UE is required to release the resource and enter the CELL_FACH state, and still use the RNTI obtained in the system message. The NodeB needs to notify the RNC to change the identifier information corresponding to the resource in the system message, because the information has been given to the UE. Occupied.

In this way, the two resource release schemes in the prior art exist that the RNC does not know when the UE releases the resources, and the RNC may not send the RRC reconfiguration message to the UE, and the UE has released the resources, thereby causing data loss.

detailed description

The embodiment of the present invention provides a method for releasing a resource, which can prevent the UE from releasing downlink data in the state that the unknown UE releases the resource, and the downlink data is lost. Lost. The embodiments of the present invention also provide corresponding base stations, RNCs, UEs, and systems. The details are described below separately.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

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

S100: The UE sends a status report that the SI=0, that is, the buffer status is “empty”, and the status report may be understood as a resource release request during the release of the implicit resource. The status report can be sent separately or in the data MAC-i PDU.

SI=0 is sent separately, indicating that the UE is ready to release resources during the implicit resource release process, that is, releasing the E-DCH resource if the RNC is unknown.

S105. The base station sends an ACK to the UE, that is, acknowledges that the status report that the buffer status sent by the UE is “empty” is received, indicating 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 and the corresponding common associated with the enhanced dedicated channel radio network temporary identifier E-RNTI used by the UE. E-DCH resources.

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

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

S120. The RNC, when not receiving the first status indication, schedules downlink data to the UE if the unknown UE has released the E-DCH resource.

S125. After receiving the downlink data scheduled for the UE, the base station directly discards the downlink data or records the corresponding data packet number, so as to notify the RNC which data is not successfully transmitted to the UE, so that the RNC is convenient. Pass the data. That is, the base station does not schedule the downlink data to the UE.

Specifically, when the RNC receives the downlink data that is scheduled by the H-RNTI to the UE, the downlink data is discarded.

Before receiving the acknowledgment response, the base station rejects the request to support the enhanced URA_PCH UE to compete for the same set of common E-DCH resources except the support enhanced URA_PCH UE, where the same set of common E-DCH resources is the enhanced URA_PCH The 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 acknowledgement response to the base station.

After receiving the first status indication, the RNC knows that the UE has released the resources. If the downlink data needs to be scheduled to the UE, the UE may receive the data by paging or directly scheduling the downlink data of the UE. In order to ensure the reliability of the data transmission, the NodeB may be required to add a timestamp to the state indication sent to the RNC, for example, it may be a system frame number (SFN), etc., to inform the RNC of the time point of the UE. The resources are released, so that the RNC can know that the data scheduled by the UE after this time point is impossible to receive, and the data can be retransmitted.

Optionally, if the UE has been allocated a dedicated H-RNTI or an E-RNTI by re-allocation signaling or other manners, the base station may only forward to the RNC during the UE performing the common E-DCH resource release process. The first status indication is sent, and the acknowledgment response sent by the RNC is not required to be received, that is, the step S130 is not needed. At this time, after receiving the downlink data scheduled for the UE, the base station, according to the H-RNTI associated with the E-RNTI, The data corresponding to the H-RNTI is discarded, while allowing other than the support enhanced URA_PCH UE to support the request that the URA_PCH UE competes for the same set of common E-DCH resources without waiting for the acknowledgment response sent by the RNC. Because these UEs use different E-RNTIs or H-RNTIs at this time, different UEs can be distinguished by this.

In the prior art, the RNC does not know when the UE releases the resource, and the RNC may not reconfigure the RRC. 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 the resource. After the UE releases the resources in the prior art, it stays in the CELL_FACH state, and the UE cannot be returned to the initial URA_PCH state. The air interface reconfiguration is required to achieve the purpose. Compared with the UE, the signaling from the Cell_FACH state to the URA_PCH state is reduced. Interaction.

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

S200. The RNC configures, for the information that the time limit of the implicit resource release timer used by the UE that supports the enhanced URA_PCH is infinitely long, or turns off the implicit resource release instruction of the UE.

The RNC configures the UE implicit resource release timer (ie, "E-DCH transmission continuation back off" to enhance the dedicated information transmission continuous backoff) to be infinity, and the RNC needs to further indicate that the UE that enhances the URA_PCH state uses the timer. For example, the value of "E-DCH transmission continuation back off for URA_PCH" may be added to the system information as "infinity", or the indication supporting enhanced URA_PCH implicit release may be turned off, or the cell support enhanced URA_PCH or URA_PCH may be added to the system information. The indication of seamless migration, the UE determines, according to the indication, that the network supports enhanced URA_PCH or supports URA_PCH seamless migration, and can predetermine that if the enhanced URA_PCH or URA_PCH seamless migration process is used, the implicit release function is turned off. Therefore, the legacy UEs of the non-enhanced URA_PCH are not affected. The legacy UEs can still perform implicit resource release, and only the UE supporting the enhanced URA_PCH cannot perform implicit release.

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

S210. The base station sends an ACK to the UE, that is, acknowledges that the status of the received UE is "empty".

However, since the duration of the timer released by the implicit resource of the UE is set to be infinitely long, the UE cannot perform implicit resource release.

Optionally, if the UE cache is not empty, the network side, for example, the base station may also decide to release the common E-DCH resource 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 the common enhanced dedicated channel common E-DCH resource.

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

The acknowledgment response may be an indication that the RNC instructs the base station to release the common E-DCH resource of the UE. The acknowledgment response may further carry configuration information that the UE is configured to enter other non-URA_PCH states after the resource is released.

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

The resource release command may 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 carried information is “INACTIVE” and the absolute authorization range is “All HARQ processes”. Release resources.

If the acknowledgment response sent by the RNC to the RNC further includes configuration information indicating that the UE resource is released and then enters another state, the base station sends the information to the UE, and then sends a resource release command to the UE.

S230: The UE releases the E-DCH resource, and after releasing the resource, returns from the Cell_FACH state to the URA_PCH state.
