Description

Method, system and related device for uplink resource allocation

The present invention relates to the field of mobile communication technologies, and in particular, to an uplink resource allocation method, system, and related apparatus. Background technique

The network side of the Long Term Evolution (LTE) network includes an Evolved Packet Core (EPC) and an Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The access network includes a base station (eNB), and the core network includes multiple core network nodes, such as a Mobility Management Entity (MME) and a Serving Gateway (S-GW). The eNB and the core network node are interconnected through the S1 interface, and each eNB can be connected to one or more core network nodes, and the eNBs are interconnected through the X2 interface. The user equipment (UE, User Equipment) and the eNB are interconnected through the XI interface. The LTE network is shown in Figure 1.

The uplink and downlink radio resources of the LTE network are scheduled by the eNB in a shared channel manner. When the UE in the initial access state needs to transmit an uplink message to the LTE network side, the eNB first requests the eNB to allocate resources, and then can use the resources allocated by the eNB to transmit the uplink. The message is sent to the eNB. FIG. 2 is a schematic diagram of a protocol message transmission process between a UE and an eNB in an initial access state in the current uplink resource allocation process, and the specific description is as follows:

Step 101: The UE in the initial access state sends a scheduling request (Schedule Request, SR) to the eNB when the uplink message needs to be transmitted to the LTE network, and requests the eNB to allocate an uplink resource for transmitting the uplink message.

Step 102: After receiving the SR, the eNB performs uplink grant, and allocates a small amount of uplink resources for transmitting signaling to the UE in the initial access state. Step 103: The UE in the initial access state sends a buffer status report (BSR) to the eNB by using a small amount of uplink resource allocated by the eNB, and requests to allocate an uplink resource for transmitting the uplink message.

Step 104: After receiving the BSR, the eNB allocates the uplink resource for transmitting the uplink message to the UE in the initial access state according to the resource status of the UE buffer indicated by the BSR.

Step 105: The UE in the initial access state transmits an uplink message to the eNB on the allocated uplink resource.

In the LTE and LTE-Advanced (LTE-A) network, when the UE in the initial access state requests the eNB to allocate the uplink resource for transmitting the uplink message, the BSR needs to report the amount of the uplink message data in the buffer to the eNB through the BSR. After the eNB performs uplink grant according to the amount of uplink message data in the UE buffer in the initial access state, the eNB allocates the uplink resource to the UE in the initial access state. In order to obtain the uplink resource for sending the BSR, the UE is in the initial access state. When the UE in the initial access state performs the uplink message transmission, it needs to send two requests for the SR and the BSR to the eNB. The eNB allocates uplink resources to the UE in the initial access state according to the SR and the BSR sent by the UE in the initial access state, and the eNB needs to perform the relationship between the UE and the eNB in the initial access state as shown in FIG. The transmission of the 4th protocol messages in steps 101 to 104 increases the air interface delay and reduces the user experience. Summary of the invention

In order to achieve the object of the present invention, in the embodiment of the present invention, based on the premise that the amount of uplink message data transmitted by the UE to the eNB in the initial access phase is relatively fixed, it is proposed that when the eNB requests the eNB to allocate the uplink resource for transmitting the uplink message in the initial access phase of the UE, It is not necessary to send a BSR, only the SR is sent to the eNB. When the UE is in the initial access state, the eNB can determine, according to the format, content, and amount of the uplink message that the UE needs to transmit and the amount of the uplink message to be transmitted, the eNB can transmit according to the UE. The uplink message is used to allocate the uplink resource that carries the uplink message to the UE, which saves the process of the UE transmitting the BSR and the corresponding eNB performing the uplink authorization according to the BSR, and reduces the allocation of the uplink resource for the UE to transmit the uplink message. The delay of the air interface control plane message.

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Embodiment 1:

As shown in FIG. 3, it is a schematic diagram of a protocol message transmission process between a UE and an eNB in an uplink resource allocation process when the UE is in an initial access state according to the first embodiment of the present invention, and the specific uplink resources are divided into:

Step 201: The eNB receives the SR reported by the UE in the initial access state.

When the UE is in the initial access state (including the state in which the UE initially accesses the network or the state in which the UE switches to the target network when the network is switched), when the UE needs to send an uplink message to the eNB, the UE reports the SR to the eNB to request the transmission of the uplink. The upstream resources required for the message.

In this step, the eNB may determine that the UE is in the initial access state by determining the current state of the UE, or the UE may carry an identifier indicating that the UE is currently in the initial access state in the specified field of the SR, where the identifier may be carried in the identifier. Among the fields occupied by the following two parameters in the SR: The highest priority logical channel to be reported message parameter or the highest priority logical channel number parameter.

Step 202: The eNB allocates uplink resources for transmitting the uplink message to the UE according to the resources that need to be occupied by the uplink message to be reported by the UE in the initial access state. When the eNB receives the SR and identifies that the UE is in the initial access state, the eNB may determine which uplink message the UE needs to transmit, because the UE is in the initial access phase, because the UE is to report the uplink in the initial access state. The message format, the content, and the amount of data are fixed. Therefore, the eNB can determine the uplink resource that needs to be allocated for the uplink message to be reported by the UE.

The eNB performs uplink grant according to the determined format, content, and data volume of the uplink message to be reported by the UE, and allocates an uplink resource that can carry the uplink message to the UE. In order to ensure the correct transmission of the uplink message and reduce the waste of the uplink resource, the uplink resource may be allocated to the UE according to the determined amount of the uplink message data to be reported, or may be equal to the determined amount of the uplink message data to be reported. The UE allocates uplink resources.

Step 203: The eNB receives an uplink message that is transmitted by the UE by using the allocated uplink resource.

The first embodiment will be described in detail below through a specific example.

Embodiment 2:

The LTE network can be divided into two types: frequency division duplex (FDD) and time division duplex (TDD) according to the duplex mode. Step 301 is followed by FIG. 4: The eNB receives the random access initiated by the UE. request.

In an LTE network, random access is a basic function. The UE can perform uplink message transmission only after performing uplink synchronization with the LTE network through a random access procedure. Random access in LTE networks is divided into contention-based random access (such as initial access) and non-contention random access (such as access during handover).

When the UE is in the radio resource control (RRC) idle state, if the user currently initiates a service, the user-initiated service will trigger the UE to start a random access procedure. At this time, the UE initiates a contention-based randomization to the eNB. The access request, the eNB receives a random access request initiated by the UE.

Step 302: The eNB sends a random access response and allocates related resources to the UE. After detecting that the UE initiates a random access request, the eNB sends a random access response to the UE, which indicates that the random access of the UE is successful, and allocates related resources for the UE to send a message to the eNB.

Step 303: The eNB receives an RRC setup request sent by the UE on the resource allocated in step 302.

After the UE succeeds in accessing the eNB, the UE needs to request to establish an RRC connection with the eNB. Therefore, the UE sends an RRC setup request to the eNB by using the resources allocated by the eNB.

Step 304: The eNB receives the RRC setup request, sends an RRC setup response, and allocates related resources to the UE.

After receiving the RRC setup request, the eNB sends an RRC setup response to the UE, indicating that the eNB can establish an RRC connection and allocate a small amount of uplink resources to the UE for reporting the SR.

Step 305: The eNB receives the SR that the UE sends by using the uplink resource allocated in step 304.

After receiving the RRC setup response, the UE needs to transmit an RRC setup complete message to the eNB, so that the UE side can also establish an RRC connection. In order to transmit the RRC setup complete message, it is first required to request, by the SR, the uplink resource required for transmitting the RRC setup complete message to the eNB.

Step 306: After receiving the SR, the eNB performs an uplink grant, and allocates, to the UE, an uplink resource that transmits an RRC setup complete message.

When the eNB receives the SR and determines that the UE is in the initial access state, it may determine that the uplink message to be reported by the UE is an RRC setup complete message, and may determine the format, content, and amount of the RRC setup complete message to be reported, thereby An uplink resource that is slightly larger or exactly equal to the determined RRC setup complete message data amount is allocated to the UE for transmission of the message. Specifically, the uplink resource size allocated for each UE is determined according to the data size of the RRC setup complete message, the number of UEs accessing the same eNB, and the channel quality of the channel used for transmitting the RRC setup complete message.

In the process of the eNB allocating uplink resources to the UE, first, the UE is negotiated with the uplink. Resource format of the row resource, the specific resource allocation format utilizes the physical downlink control channel

Downlink Control Information (DCI) in the (Physical Downlink Control Channel, PDCCH) determines that the format of the DCI can be classified into DCI0, DCI1, DCI2, and the like. In the embodiment of the present invention, a resource using the DCI0 format is determined. After the resource allocation format is negotiated, the eNB sends an indication message to the UE for indicating the size and location of the allocated uplink resource, where the indication message is used to indicate that the UE monitors the specified location according to the negotiated resource format. The resource transmission RRC setup complete message of the specified size is occupied when the time slot specified by the indication message arrives.

Step 307: The eNB receives an RRC setup complete message sent by the UE on the allocated uplink resource.

After the eNB is instructed to select the resource in the DCI0 format, if the UE detects the resource in the DCI0 format, the UE monitors the resource, and the eNB indicated by the indication message transmits an RRC setup complete message to the eNB for the allocated uplink resource, if the eNB Receiving an RRC setup complete message sent by the UE, indicating that the RRC connection establishment between the eNB and the UE is successful.

Through the foregoing steps 301 to 307, when the UE in the initial access state accesses the access network, the eNB allocates uplink resources to the UE, and implements uplink message transmission. In the uplink resource allocation process (steps 305 to 306), the eNB determines that the data is fixed according to the fact that the UE is in the initial access state and the RRC setup complete message to be reported is not required to be reported by the UE. The RRC establishes the resources required to complete the message, and allocates the uplink resource for transmitting the RRC setup complete message to the UE, thereby reducing the process of the UE transmitting the BSR and the corresponding eNB performing the uplink grant according to the BSR, and reducing the air interface delay.

The flow of the uplink resource allocation of the UE accessing the core network is further described on the basis of steps 301 to 307.

Step 308: After receiving the RRC setup complete message, the eNB sends a UE initialization message to the core network. Step 309: The eNB receives an initial context setup message sent by the core network.

After receiving the UE initialization message sent by the eNB, the core network sends an initial context setup message to the eNB, indicating that the core network can establish a connection with the UE.

Step 310: After receiving the initial context setup message, the eNB sends an RRC reconfiguration message and allocates related resources to the UE.

After receiving the initial context setup message, the eNB determines that the core network can establish a connection with the UE. To establish an RRC connection between the UE and the core network, the eNB sends an RRC reconfiguration message to the UE, and allocates a small amount of uplink resources for the UE to report the SR.

Step 311: The eNB receives the SR reported by the UE.

After the UE receives the RRC reconfiguration message sent by the eNB, if it is determined that the RRC connection can be established with the core network, the RRC reconfiguration complete message needs to be transmitted to the eNB. Before the UE transmits the RRC reconfiguration complete message to the eNB, it is first necessary to request, by the SR, the resource required for transmitting the RRC reconfiguration complete message to the eNB.

Step 312: After receiving the SR, the eNB performs uplink grant, and allocates a reasonable resource for transmitting the RRC reconfiguration complete message to the UE.

In the same step 306, the eNB may determine that the uplink message to be reported is an RRC reconfiguration complete message, and the format, content, and data volume of the RRC reconfiguration complete message, and the eNB may determine to be reported according to the eNB. The RRC reconfiguration completes the message format, content, and amount of data, and allocates an uplink resource for the UE to carry the RRC reconfiguration complete message.

Step 313: The eNB receives an RRC reconfiguration complete message that the UE transmits to the allocated uplink resource.

After the uplink resource allocation succeeds, the UE transmits the RRC reconfiguration complete message to the eNB by using the allocated resources, indicating that it can establish an RRC connection with the core network.

Step 314: The eNB sends an initial context setup response to the core network.

After receiving the RRC reconfiguration complete message that the UE can establish an RRC connection with the core network, the eNB receives the RRC reconfiguration complete message. Sending an initial context setup response to the core network, notifying the RRC connection establishment of the core network and the UE. At this point, the uplink resource allocation of the eNB to the UE in the initial access state when the core network is accessed is completed, and the uplink message transmission is implemented.

Steps 301 to 314 can be regarded as a complete process of resource allocation and uplink message transmission, where two uplink resource allocation processes are involved, and the amount of uplink message data transmitted to the eNB according to the initial access state of the UE is relatively fixed. In the first resource allocation process (steps 305 to 306), the process of the UE transmitting the BSR and the corresponding eNB allocating resources according to the BSR for the RRC setup complete message is reduced, and the air interface delay is reduced; (Step 311 to Step 312), receiving the SR sent by the UE, and allocating the uplink resource to the UE according to the RRC reconfiguration complete message to be reported by the UE, and allocating the uplink resource for transmitting the RRC reconfiguration complete message to the UE, reducing the BSR and corresponding The eNB allocates resources according to the BSR for the RRC reconfiguration complete message, so that when the UE accesses the core network, the protocol message transmission can be reduced by four times, thereby reducing the air interface delay twice and saving the UE access time.

It should be noted that steps 301 to 307 and steps 308 to 314 may constitute two complete processes of resource allocation and uplink message transmission, and constitute two independent embodiments. That is, the eNB allocates uplink resources for the RRC reconfiguration complete message, and can also be regarded as a technical solution for the eNB to allocate uplink resources in parallel for the RRC setup complete message.
