Description

Method, device and system for controlling credit resource allocation of uplink enhanced dedicated channel

technical field

The present invention relates to the field of communication technology, in particular to a method, device and system for controlling credit resource allocation of an uplink Enhanced Dedicated Channel (EDCH).

Background technique

The uplink enhanced dedicated channel technology introduced by the 3rd Generation Partnership Project (3GPP) is also called High Speed Uplink Packet Access (HSUPA), which can realize high-speed uplink data transmission. In 3GPP, the radio network controller (Radio Network Controller, RNC) manages its subordinate base stations, and can manage the resource information of the subordinate cells of the base station, such as power resources, Iub interface transmission resources, credit resources, code resources, etc.

Wideband Code Division Multiple Access (WCDMA) communication system is a code division system, that is, different user equipment can be distinguished by using different channelization codes, and can be spread by using Spreading Factor (SF). Frequency, that is, SF chips represent a data symbol, and SF can be understood as a spreading factor. For the base station, each call will occupy part of the processing capacity of the base station, and the smaller the spreading factor of the user, the more processing capacity of the base station will be occupied. Since the processing capability of the base station chip is limited, the radio network controller must limit the number of users accessing the cell. For this reason, 3GPP introduces the concept of capability credit and consumption law:

1. Quantify the processing capability of the base station into a capability credit, and report the quantified result, that is, the capability credit, to the radio network controller. For example, the capability credit of the local cell is 100.

2. Report the amount of capability credits to be consumed by each spreading factor to the RNC in the form of spreading factor consumption rules. For example, suppose an AMR voice user with a spreading factor of 128 consumes a capability credit of 2, and a 384K PS service with a spreading factor of 8 consumes a capability credit of 12.

3. When the radio network controller pre-allocates credit resources, each time a user is connected, it calculates the required capacity credits according to the spreading factor of the user, and checks whether the remaining capacity credits of the local cell are sufficient, and the remaining capacity credits of the local cell The capability credit of the local cell is the capability credit of the local cell minus the total capability credit occupied by the connected users. If it is insufficient, it means that the processing capacity of the base station is almost exhausted and has no ability to process the user, and the radio network controller should reject the user's resource application; if it is sufficient, it means that the base station has the ability to process the user, and the radio network controller can accept the user resource application.

The base station can report the capability credit of the local cell corresponding to the cell, the consumption rules corresponding to each spreading factor, and the capability of the local cell group to which the cell belongs through the Resource Status Indication (Resource Status Indication) message and the cell's Audit Response (Audit Response) message. Credit and corresponding consumption rules for each spreading factor.

Currently, the audit process between the radio network controller and the base station includes:

Step 102: When the base station finds that its own capability state changes or the base station restarts, etc., it needs to notify the radio network controller of its own resource capability, and send an Audit Required Indication (Audit Required Indication) message to the radio network controller, Ask the wireless network controller to send the audit process.

Step 104: The radio network controller decides to initiate an audit process according to the audit request indication message of the base station, and sends an audit request message to the base station.

Optionally, the radio network controller may also send the audit process according to its needs, that is, directly send the audit request message to the base station without step 102 .

Step 106: After receiving the audit request message, the base station reports its credit resource status to the radio network controller through an audit response (Audit Response) message.

If an audit response message cannot report all credit resources in the base station to the radio network controller, repeat steps 104 and 106 until the reporting is completed.

In a WCDMA communication system, multiple transmission channels can be multiplexed into the same physical channel, and each transmission channel has its own attributes. Among them, the dynamic attributes of the transmission channel include transmission within the Transmission Timing Interval (TTI). The variable bit rate of the transmission channel is realized by changing the transmission block size and the number of transmission blocks between each transmission time interval. It can be considered that terminals with different transmission time intervals have different consumption rules under the same spreading factor. One of the characteristics of high-speed uplink packet access is that the air interface uses short frames with a transmission time interval of 10 milliseconds or 2 milliseconds. When the service is carried on the high-speed uplink packet access channel, configuring the transmission time interval of the high-speed uplink packet access channel as 2 milliseconds can provide a higher peak uplink rate than configuring the transmission time interval as 10 milliseconds. The consumption law corresponding to the transmission time interval of 10 milliseconds is different from the consumption law corresponding to the transmission time interval of 2 milliseconds. At present, the base station only reports a spreading factor consumption law of the uplink enhanced dedicated channel, that is, only reports the spreading factor consumption law of the uplink enhanced dedicated channel for users whose transmission time interval is 2 milliseconds or only reports the consumption rule for the transmission time interval of 2 ms The spreading factor consumption law of the user's uplink enhanced dedicated channel for 10 ms.

Detailed ways

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 part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The inventors found that because the base station only reports the spreading factor consumption law of the uplink enhanced dedicated channel for users whose transmission time interval is 2 milliseconds or only reports the spreading factor consumption law of the uplink enhanced dedicated channel for users whose transmission time interval is 10 milliseconds , so that the radio network controller cannot accurately admit users, that is, the radio network controller cannot accurately control the allocation of credit resources of the uplink enhanced dedicated channel. The following example illustrates the problem:

Assuming that when the transmission time interval is 2 milliseconds for users, the consumption capacity credit of spreading factor 4 is 6, that is, it needs to consume 6 channel elements of the base station. When the transmission time interval is 10 milliseconds for users, the consumption capacity of spreading factor 4 The credit level is 7, that is, it needs to consume 7 channel elements of the base station. The value of the capability credit of the base station is constant, that is, the total channel element size is fixed. If the radio network controller accesses both users with a transmission time interval of 2 milliseconds and users with a transmission time interval of 10 milliseconds, when the radio network controller performs user access according to the spreading factor consumption rule with a transmission time interval of 2 milliseconds , that is, for users with a transmission time interval of 10 milliseconds, the spreading factor consumption rule with a transmission time interval of 2 milliseconds is used for user access to calculate the remaining capacity credit of the local cell. The frequency factor consumption law is used for user access, so the wireless network controller will access some more users, but the remaining capacity credit of the base station is actually unable to handle so many users; When the consumption law is used for user access, that is, for users with a transmission time interval of 2 milliseconds, the spreading factor consumption law with a transmission time interval of 10 milliseconds is also used for user access to calculate the remaining capacity credit of the local cell. Due to wireless network control All routers perform user access according to the spreading factor consumption rule of 10 milliseconds, so the wireless network controller will access a part of users less, but the remaining capacity credits of the base station can actually handle this part of user access.

Therefore, the inventor found that it is necessary for the base station to report different spreading factor consumption rules of the uplink enhanced dedicated channel according to different transmission time intervals, so as to keep the spreading factor consumption rules of the radio network controller consistent with the spreading factor consumption rules of the base station. Therefore, the utilization rate of the uplink enhanced dedicated channel resource is improved, the capability of the base station is fully utilized, and the flexibility of the system is improved.

An embodiment of the present invention provides a method for controlling credit resource allocation of an uplink enhanced dedicated channel, including: a radio network controller receives a first message sent by a base station and includes information on a spreading factor consumption rule, the spreading factor consumes The rule information includes each spreading factor consumption rule of the terminal at different transmission time intervals, and the spreading factor consumption rule indicates the credit of the uplink enhanced dedicated channel consumed by each spreading factor of the terminal at a transmission time interval ; The radio network controller controls the allocation of the credit resource of the uplink enhanced dedicated channel according to the information of the spreading factor consumption law.

In the embodiment of the present invention, when the terminal has only one transmission time interval, the size of the capability credit of the base station that each spreading factor of the terminal needs to consume can be called the spreading factor consumption rule of the terminal under the transmission time interval . When the terminal has different transmission time intervals, the terminal may have a corresponding spreading factor consumption rule for each transmission time interval. The information composed of these different spreading factor consumption laws may be referred to as information of spreading factor consumption laws. The spreading factor depletion law may also be referred to as the channel element depletion law.

By using the method in the embodiment of the present invention, the radio network controller can know the consumption rules of each spreading factor reported by the base station including the terminal at different transmission time intervals, so as to avoid the situation that the radio network controller allows more access to some users and the base station In fact, the capability of the base station cannot handle the access of this part of users, or the radio network controller rejects the access of some users, but the capability of the base station can actually handle the access of this part of users. Therefore, it is possible to improve the resource utilization rate of the credit of the uplink enhanced dedicated channel, reduce unnecessary user access by the radio network controller, thereby reducing the wrong access of the radio network controller to the user, and also reducing the radio network control The processing task of the processor improves the flexibility of the system.

Embodiments of the present invention provide yet another method for controlling credit resource allocation of an uplink enhanced dedicated channel, including: the base station sends a first message including information on a spreading factor consumption law to a radio network controller, and the spreading factor consumption law The information includes the consumption rules of each spreading factor of the terminal under different transmission time intervals, and the spreading factor consumption law indicates the credit of the uplink enhanced dedicated channel consumed by each spreading factor of the terminal under a transmission time interval; the corresponding spreading factor For the information of the consumption law, the base station receives the second message sent by the radio network controller that includes the information of the spreading factor assigned to the terminal; according to the information of the spreading factor consumption law and the spreading factor corresponding to the terminal, the base station controls Allocation of credit resources of the uplink enhanced dedicated channel for the terminal.

Using the method in the embodiment of the present invention, the base station can notify the radio network controller of each spreading factor consumption law of the terminal under different transmission time intervals. Since the radio network controller can know the ability of the base station to access the user according to the spreading factor consumption law corresponding to the terminal at different transmission time intervals, when the radio network controller allows the user to access, there will be no radio network control In the case that the actual processing capability of the base station cannot handle the users who are allowed to access by the router, the base station can avoid processing these users who are actually unable to access; at the same time, because the radio network controller knows that the terminal reported by the base station is in the The corresponding spreading factor consumption law under different transmission time intervals, so that the radio network controller can accurately perform user access according to the corresponding spreading factor consumption law of the terminal under different transmission time intervals, so that the processing capability of the base station can be be fully utilized.

Further description will be made below in conjunction with specific implementation methods and accompanying drawings.

For the convenience of description, the embodiment of the present invention only uses an example for a terminal with a transmission time interval of 2 milliseconds and a terminal with a transmission time interval of 10 milliseconds, but those skilled in the art can understand that the solution of the present invention is not limited to the transmission time The terminal with an interval of 2 milliseconds and the terminal with a transmission time interval of 10 milliseconds, this example description does not constitute a limit to the scope of the present invention, and the scope of protection of the present invention should be based on the scope of claims.

As shown in FIG. 1, an embodiment of the present invention provides a method for controlling credit resource allocation of an uplink enhanced dedicated channel, including:

1010: The radio network controller receives the first message reported by the base station that includes the information of the spreading factor consumption law, and the information of the spreading factor consumption law may include the spreading factor consumption law and Spreading factor consumption law at a transmission time interval of 10 ms.

The base station can report the information of the spreading factor consumption law of the terminal in the local cell to the radio network controller through the audit response message, that is, the first message is the audit response message, and the information element of the channel element consumption law of the audit response message includes the terminal The spreading factor depletion law at a transmission time interval of 2 ms and the spreading factor depletion law at a transmission time interval of 10 ms. Therefore, the radio network controller can obtain the information of the spreading factor consumption law of the terminal through the audit response message. Optionally, the base station may report the information of the spreading factor consumption rule of the terminal in the local cell to the radio network controller through a resource status indication (Resource Status Indication) message, that is, the first message is a resource status indication message.

1020: The radio network controller controls the allocation of the credit resources of the uplink enhanced dedicated channel according to the information of the spreading factor consumption rule reported by the base station.

Since the radio network controller has received the spreading factor consumption law when the transmission time interval of the terminal in the local cell reported by the base station is 2 milliseconds and the spreading factor consumption law when the transmission time interval is 10 milliseconds, so when the transmission time interval is 2 When the first terminal accesses within milliseconds, the radio network controller can determine the capacity credits that the user needs to occupy according to the spreading factor consumption law when the transmission time interval of the first terminal is 2 milliseconds, and judge whether the base station has ability to process the user's access, similarly, when the second terminal with a transmission time interval of 10 milliseconds accesses, the radio network controller can Determine the capacity credits that the user needs to occupy, and use this to determine whether the base station has the ability to handle the user's access. Therefore, the radio network controller will not use the spreading factor depletion law when the transmission time interval of the terminal is 2 ms to judge whether the base station is capable of handling the access of the terminal when the transmission time interval is 10 ms, nor will it use The spreading factor depletion law with a transmission time interval of 10 milliseconds is used to determine whether the base station is capable of handling terminal access when the transmission time interval is 2 milliseconds. Therefore, the radio network controller can avoid multiple access users whose base station capabilities cannot actually handle the access of these users, thereby reducing unnecessary user access by the radio network controller and avoiding the radio network controller from rejecting The capability of the base station can actually handle the access of users, thus improving the processing utilization rate of the base station capability and the utilization rate of the credit resources of the uplink enhanced dedicated channel.

1040: According to the transmission time interval of the terminal, the radio network controller determines a spreading factor consumption law corresponding to the terminal.

If the terminal supports a transmission time interval of 2 milliseconds and a transmission time interval of 10 milliseconds, and the current cell supports both a transmission time interval of 2 milliseconds and a transmission time interval of 10 milliseconds, then the radio network controller will report the request according to the The rate determines whether the terminal is carried on the transmission time interval of 2 milliseconds or on the transmission time interval of 10 milliseconds. Since the wireless network controller stores the spreading factor consumption law of the terminal under different transmission time intervals, when the wireless network control When the controller determines that the terminal bears the bearer in a certain transmission time interval, the radio network controller can know the spreading factor consumption law of the terminal in the transmission time interval.

1050: According to the rate information requested by the terminal and the spreading factor consumption rule corresponding to the terminal, the radio network controller controls the allocation of the credit resources of the uplink enhanced dedicated channel for the terminal.

According to the information of the rate requested by the terminal, the radio network controller can negotiate with the core network to determine a maximum available rate supported by it. The radio network controller can determine the spreading factor corresponding to the maximum available rate according to the spreading factor consumption law corresponding to the terminal in the transmission time interval, and the spreading factor is the radio network controller determines to allocate to the terminal Spreading factor.

The radio network controller may carry the information of the spreading factor allocated to the terminal to the base station through a radio link reconfiguration preparation message or a radio link establishment message.

By adopting the method in the embodiment of the present invention, the information of the spreading factor consumption law of the radio network controller can be consistent with the information of the spreading factor consumption law of the base station, that is, the radio network controller can know that the terminal reported by the base station is in different transmission The spreading factor depletion law corresponding to the time interval can avoid the situation that the radio network controller allows more access to some users, but the base station's capability cannot actually handle this part of the multi-access users, or the radio network controller rejects some users The access of the base station can actually handle the access of this part of users. Therefore, it is possible to improve the utilization rate of the credit resource of the uplink enhanced dedicated channel, and reduce unnecessary user access by the radio network controller, thereby reducing the wrong access of the radio network controller to the user, and also reducing the processing tasks, improving the flexibility of the system.

2020: Corresponding to the information of the spreading factor depletion rule, the base station receives a second message sent by the radio network controller that includes the information of the spreading factor allocated to the terminal.

When a terminal requests access, the terminal may carry the rate requested by the terminal in the radio resource control connection request message.
