Description

The method for reporting the credit consumption rule, the method and the device for admission control The application is submitted to the Chinese Patent Office on February 1st, 2010, and the application number is 201010110590. 5 , the invention name is "a credit consumption law reporting method, standard The priority of the Chinese Patent Application, which is incorporated herein by reference. Technical field

3GPP (3rd Generation Partnership Project) R7 (Release 7, 3GPP R7 version) After introducing UL 16QAM (Uplink 16 bit Quadrature amplitude modulation), the maximum peak rate of uplink reaches 11.498. Mbps, which is 2 times the original.

CE (channel element) reflects the modulation and demodulation capability of the base station NodeB. The modulation and demodulation capability of a NodeB is usually fixed, and the NodeB-determined modulation and demodulation capability is consumed for each service establishment. According to the CE consumption rule of different services, the RNC (Radio Network Controller) can infer how many different types of services the NodeB can establish. During the admission control process, the RNC determines whether the NodeB has the ability to establish or modify the service to determine whether to access the service request sent by the user equipment through the HSUPA (High Speed Uplink Packet Access) channel.

Since the CE consumption rule of the prior art only considers a modulation method of QPSK (Quadature Phase Shift Keying), the CE consumption rule generated by the base station of the prior art only depends on the spreading factor, that is, The consumption of CE is only related to the spreading factor. After the introduction of UL 16QAM, the NodeB consumes the CE and the original demodulated QPSK when demodulating the UL 16QAM modulated signal. The CE consumed by the modulated signal is different. Using the existing calculation method will cause the RNC to calculate the CE consumption error. When the RNC incorrectly estimates that the NodeB can establish or modify the service and send a configuration message to the NodeB, the NodeB will return a configuration failure, resulting in a large number of failure procedures for the IUB interface between the RNC and the NodeB.

It contains the consumption rule of the spreading factor under different modulation modes of HSUPA.

The first embodiment of the present invention provides a technical solution, in which the NodeB generates a CE consumption rule according to different modulation modes and spreading factors, and reports the CE consumption rule, so that the RNC can correctly calculate the CE consumption of the NodeB, and accurately accurate the user. Ingress control avoids a large number of failure processes in the IUB interface between the RNC and the NodeB. The specific process by which the RNC calculates the credit consumption of the NodeB will be described in detail in the subsequent embodiments.

Embodiment 2: Embodiment 2 of the present invention provides an admission control method for a high speed uplink packet access service.

FIG. 3 is a flow chart of a method for admission control of a high speed uplink packet access service according to Embodiment 2 of the present invention. As shown in Figure 3, the method includes:

5301. Obtain logical resource information of a base station, where the logical resource information includes a credit consumption rule corresponding to different modulation modes and different spreading factors, and a total credit value of the base station.

Optionally, the logical resource information of the base station may be obtained through an audit process or a resource status indication process.

Optionally, the logical resource information may further include cell capability information, for example, whether the cell supports HSDPA, HSUPA, UL 16QAM, and the like.

For example, in the foregoing process, the audit response message or the resource status indication message may be obtained by receiving the audit response message or the resource status indication message, and the 16QAM for the modulation mode is HSUPA, and the spreading factor is 2. * Credit consumption rules for SF2+2*SF4.

Optionally, the audit response message or the resource status indication message may also carry the CE consumption rule for the modulation mode as QPSK and different spreading factors.

S302, obtaining, according to the consumption rule, a credit value accumulated by the base station, and obtaining a remaining credit of the base station according to the total credit value of the base station and the accumulated credit value. Usability value;

In an optional implementation, the RNC records the number of services that the NodeB has established and the type of service (that is, the combination of different modulation modes and spreading factors), and generates the CE value consumed by each service according to the consumption rule. Therefore, the RNC can obtain the accumulated CE value of the NodeB, and obtain the remaining CE value of the NodeB according to the total CE value reported by the NodeB, so as to use the remaining CE value of the NodeB to perform the admission decision.

For example, assuming that the total credit value of the NodeB is 256, after the NodeB has successfully established a service with a modulation mode of UL QPSK and a spreading factor of SF16, the RNC can query that the CE value of the service is 10 according to Table 1. By subtracting the consumed CE value 10 from the total CE value 256 of the NodeB, the remaining CE value of the NodeB is 246.

S303. Receive a service request sent by the user equipment by using a high-speed uplink packet access channel.

5304. Obtain a credit value that needs to be consumed by the service request according to the consumption rule. For example, refer to Table 1. According to the consumption rule reported by the NodeB, the RNC can obtain services corresponding to different modulation modes and spreading factors. The CE value consumed.

S305. Admit the service request of the user equipment when the requested service needs to consume a credit value that is less than a remaining credit value of the base station.

For example, the number of services that the NodeB can establish is UL QPSK and the spreading factor is SF4, because 15*17=255<256; for example, the corresponding modulation mode that the NodeB can establish is UL 16QAM and the spreading factor is The number of 2*SF2+2*SF4 services is 8, because 32*8=256.

For example, it is assumed that the total CE value of the NodeB is 256. According to Table 1, for example, the number of services that the NodeB can establish is UL QPSK and the spreading factor is 2*SF2+2*SF4, because 22 X 11=242<256, after establishing 11 services of this type, the NodeB accumulates the CE value of 242, so the remaining CE value of the NodeB is 14, which is insufficient to support the establishment of additional services of this type, so the RNC rejects The 12th type of service request; and when there is a service request with UL QPSK and a spreading factor of SF8, due to its The consumed CE value is 12, which is smaller than the remaining CE value of the NodeB. Therefore, the RNC grants the service request, and allows the NodeB to establish the service.

In another optional implementation, after the accessing the service request of the user equipment, the method may further include:

A radio link setup request (RADIO LINK SETUP REQUEST) message and/or a RADIO LINK ADDITION REQUEST message and/or a RADIO LINK RECONFIGURATION message are sent to the base station. The above-mentioned messages jointly implement a radio resource allocation process between the RNC and the NodeB, and establish an RRC (Radio Resource Connection) connection for the requested service.

FIG. 4 is a flowchart 1 of signaling interaction according to Embodiment 2 of the present invention. As shown in Figure 4, the process of controlling the access of the HSUPA service through the signaling interaction between the RNC and the NodeB includes:

5401. The RNC sends an AUDIT REQUEST message to the NodeB to audit the logical resource information of the NodeB. The logical resource information includes cell capability information, such as whether to support HSDPA, HSUPA, UL 16QAM, and the current CE value of the NodeB;

5402. The RNC receives the AUDIT RESPONSE message sent by the NodeB, and obtains the logical resource information of the NodeB. It contains the CE consumption rule for different spreading factors in different modulation modes of HSUPA. For details, please refer to Table 1 of Embodiment 1 and details are not described herein.

For example, the modulation method can be QPSK or UL 16QAM.

The RNC initiates a cell establishment process according to the logical resource information reported by the NodeB. For example, the foregoing process may include: the RNC establishes HSUPA, HSDPA, and the like in the cell according to the logical resource information reported by the NodeB. The RNC sends a cell setup request message to the NodeB, where there is HSUPA configuration information, and then the NodeB establishes a cell according to the content of the message, configures HSUPA, and then returns a cell setup response message.

5404. When the user access or the service establishment process uses the HSUPA, the RNC determines whether the NodeB has sufficient resources to use according to the CE consumption rule of the spreading factor in the different modulation modes of the HSUPA reported by the NodeB, so as to perform the service request of the user equipment. Admission control. The method may further include: if the RNC determines that the NodeB has sufficient CE resources to establish a service requested by the user equipment, where the resource is a modulation and demodulation capability, then perform S405-S408; otherwise, if the RNC determines that the NodeB does not have sufficient resources, S405-S408 is not executed because the NodeB returns a failure message even if the above message is sent.

S405-S408, the RNC sends a RADIO LINK SETUP REQUEST message or a RADIO LINK ADDITION REQUEST message or a RADIO LINK RECONFIGURATION PREPARE message to the NodeB; the NodeB returns a success message, that is, returns a RADIO LINK SETUP RESPONSE message or RADIO LINK ADDITION RESPONSE Message or RADIO LINK RECONFIGURATION READY message. It should be noted that S407-S408 is an optional step.

FIG. 4a is a second flowchart of signaling interaction according to Embodiment 2 of the present invention. As shown in Figure 4a, the RNC and the NodeB exchange signaling to control the admission of the HSUPA service. When the admission is allowed, the RNC can also send a radio link add message to the NodeB. The process includes:

The S401a and the NodeB are changed. If the module is faulty or a new board is inserted, a RESOURCE STATUS INDICATION message is sent to the RNC to inform the RNC of the new logical resource information of the NodeB. It includes the consumption rule of the spreading factor in different modulation modes of HSUPA. According to the consumption rule, the RNC can correctly estimate the HSUPA resource consumption of the NodeB. Otherwise, it will lead to error estimation, which will generate a large number of failure processes on the IUB interface.

S402a, performing admission control on a service request of the user equipment;

Specifically, when the user access or the service establishment process uses the HSUPA, the RNC determines whether the NodeB has resources available according to the consumption rule of the spreading factor in the different modulation modes of the HSUPA reported by the NodeB. When there is a resource that can satisfy the service, the service is admitted, and vice versa.

S403a-S408a: After allowing admission to the service, sending a RADIO LINK SETUP REQUEST message or a RADIO LINK ADDITION REQUEST message or a RADIO LINK RECONFIGURATION PREPARE message to the NodeB, the NodeB returns a success message; If the service is denied access, the RADIO LINK SETUP REQUEST message or the RADIO LINK ADDITION REQUEST message or the RADIO LINK RECONFIGURATION PREPARE message is not sent to the NodeB, otherwise the failure message is returned even if the message NodeB is sent.

In the second embodiment, the NodeB reports the spreading factor consumption rule of the HSUPA UL16QAM modulation mode to the RNC in the AUDIT RESPONSE message or the RESOURCE STATUS INDICATION message, and the RNC can correctly estimate the HSUPA resource consumption of the NodeB, otherwise the error estimation may be caused. Thus, the IUB interface between the RNC and the NodeB generates a large number of failure processes.

It should be understood by those skilled in the art that the above is only one embodiment of the present invention. In other embodiments of the present invention, the NodeB may also notify the CE consumption rule corresponding to different modulation modes and spreading factors by other messages. RNC.

The access control method for the high-speed uplink packet access service provided by the second embodiment of the present invention obtains the logical resource information of the base station, where the logical resource information includes the credit degrees of the base station corresponding to different modulation modes and different spreading factors. The consumption rule, and the total credit value of the base station; and comparing the CE value consumed by the service requested by the user equipment with the current CE value of the base station, to achieve accurate access to the service requested by the user equipment control. It also avoids the large number of failure processes in the IUB interface between RNC and NodeB.
