Embodiment 1

This embodiment provides a method for guaranteeing the quality of service. The specific processing flow is as shown in FIG. 1 and includes the following processing steps:

Step 11: The base station receives a data frame that is sent by the base station control device and carries the GBR information related to the E-FACH user.

WCDMA (Wideband Code Division Multiple) In the Access, Wideband Code Division Multiple Access system, the above base station control device is an RNC (Radio Network) Controller, radio network controller), the base station is a NodeB. It can be understood that in other systems, the base station control device and the base station may have different names.

The above-mentioned E-FACH user-related GBR information may include: GBR information for a single E-FACH user, or GBR information for a single service queue, one of which corresponds to a service type of the E-FACH user.

Step 12: The base station acquires the GBR information carried in the data frame, and performs QoS control on the E-FACH user according to the GBR information.

When the GBR information is the GBR information for the single E-FACH user, the NodeB guarantees the resource corresponding to the GBR information corresponding to the single E-FACH user when the resource is allocated according to the GBR information.

When the GBR information is GBR information for a single service queue, the NodeB guarantees resources corresponding to the GBR information corresponding to the single service queue when the resources are allocated according to the GBR information.

As shown in the technical solution provided by the foregoing embodiment, the base station control device sends a data frame carrying the GBR information related to the E-FACH user to the base station, so that the base station can perform effective QoS control on the E-FACH user according to the GBR information.

Embodiment 2

Taking the WCDMA system as an example, this embodiment provides a method for performing QoS control on an E-FACH user. The specific processing flow is as shown in FIG. 2, and includes the following processing steps:

Step 21: UE of the E-FACH user (User In the process of establishing a link connection with the network side, the equipment, the user equipment sends signaling of the user information carrying the E-FACH user to the network side.

The user information may include a user identifier, and may further include at least one of a user level, a service type, and a service attribute.

Illustratively, the foregoing user level may be: a VIP user, a normal user, a high-capacity user, a low-capacity user, and the like; the foregoing service type may include: a payment service, a browsing web service, or a download service; for the download service, the foregoing service attribute may be Including: download rate, upload rate, transmission delay, and so on.

Step 22: The RNC on the network side acquires user information of the E-FACH user, and sets GBR information for a single E-FACH user.

Specifically, the RNC may set GBR information for a single E-FACH user according to at least one of a user level, a service type, a service attribute, and the like included in the user information of the E-FACH user.

After acquiring the user information of multiple E-FACH users, the RNC can separately set the GBR information for each E-FACH user. In addition, the RNC may not set GBR information for unimportant E-FACH users.

Step 23: The RNC sends a data frame carrying the GBR information for the single E-FACH user to the NodeB.

Since the E-FACH user does not have a dedicated dedicated channel construction process, the NodeB cannot obtain the GBR information related to the E-FACH user through signaling. Therefore, in the embodiment of the present invention, the RNC sends the GBR information for the single E-FACH user to the NodeB through the data frame.

Specifically, the foregoing data frame may be an RNC through an IUB (Interface between the NodeB and The RNC, the interface between the NodeB and the RNC) transmits the HS-DSCH Frame protocol type 2 frame to the NodeB. To do this, you first need to be at HS-DSCH The GBR field is added to the Frame protocol type2 frame. Exemplarily, an HS-DSCH Frame protocol with an added GBR field The schematic diagram of the type2 frame is shown in Figure 3, in the HS-DSCH Frame protocol in Figure 3. The type2 frame is composed of a header (header) and a load (payload), wherein the spare field in the Payload represents an idle field, and the added GBR field in the Payload can be regarded as an extension of the spare field and carried in the above GBR field. The above GBR information for a single E-FACH user.

It can be understood that the user identifier of the E-FACH user is also carried in the foregoing data frame.

Step 24: The NodeB acquires the foregoing user identifier and GBR information for a single E-FACH user carried in the data frame, and performs QoS control on the E-FACH user according to the GBR information.

The NodeB guarantees resources corresponding to the GBR information corresponding to the single E-FACH user when the resource is allocated according to the GBR information.

For example, the NodeB can allocate a bandwidth rate resource of 100M, and the NodeB accesses the E-FACH user 1, the E-FACH user 2, and some other E-FACH users. The GBR information for the E-FACH user 1 is 50M, and the GBR information for the E-FACH user 2 is 30M. Other E-FACH users do not have corresponding GBR information.

Therefore, when allocating the bandwidth rate resource, the NodeB first guarantees the bandwidth rate resource corresponding to the GBR information of the E-FACH user 1 and the E-FACH user 2, that is, allocates 50M to the E-FACH user 1, and allocates the E-FACH user 2 to the E-FACH user 2. 30M, the remaining 20M is reassigned to other E-FACH users.

As can be seen from the technical solution provided by the foregoing embodiment of the present invention, the embodiment sends a data frame carrying the GBR information for a single E-FACH user to the NodeB through the RNC, and the NodeB can refer to the GBR information to different E-FACH users. The resources are allocated to ensure the resources of the EFACH user service corresponding to the GBR information. Therefore, the NodeB provides differentiated guarantee for different EFACH users, implements effective QoS control for E-FACH users, and improves the satisfaction of E-FACH users.

Embodiment 3

Taking the WCDMA system as an example, this embodiment provides a method for performing QoS control on an E-FACH user. The specific processing flow is as shown in FIG. 4, and includes the following processing steps:

Step 41: The UE of the E-FACH user sends signaling of the user information of the E-FACH user to the network side in the process of establishing a link connection with the network side, where the user information may include a user identifier, optionally The method may further include: at least one of a user level, a service type, a service attribute, and the like.

Illustratively, the foregoing user level may be: a VIP user, a normal user, or the like; the foregoing service type may include: a payment service, a browsing web service, or a download service, etc.; for the download service, the foregoing service attributes may include: a download rate, a server address , the address of the client, and so on.

Step 42: The RNC on the network side acquires user information of the E-FACH user, and sets GBR information corresponding to a single service queue.

The RNC can also obtain information about various service queues maintained by the network side. The foregoing service queue can be in the MAC (Media Access). Control, Media Access Control) The MAC-ehs queue established by the layer. One of the above service queues corresponds to a service type. For example, the download service corresponds to one download queue, and the payment service corresponds to one payment queue. A service queue can include the same service of multiple E-FACH users.

The RNC can obtain the service queue information to which the various services corresponding to the E-FACH user belong according to the service type information included in the user information of the E-FACH user.

Then, the RNC sets GBR information corresponding to a single service queue according to at least one of the user information of the E-FACH user and the service type and service attribute corresponding to the various service queues. In addition, the RNC may not set GBR information for unimportant traffic queues.

Step 43: The RNC sends, to the NodeB, a data frame that carries the GBR information for the single service queue.

Since the E-FACH user does not have a dedicated dedicated channel establishment process, the NodeB cannot obtain the GBR information of the E-FACH user-related service queue through signaling. Therefore, in the embodiment of the present invention, the RNC sends the GBR information for a single service queue to the NodeB through the data frame.

Specifically, the foregoing data frame may be an HS-DSCH Frame protocol sent by the RNC to the NodeB through the IUB interface. Type2 frame in HS-DSCH Frame protocol The header field in the Header and Payload of the type2 frame represents the idle field. The GBR field added in the Payload can be regarded as an extension of the spare field, and the GBR information for the single service queue is configured in the GBR field.

And, SPI (Schedule PRI) in the above data frame The indication, the scheduling priority indication field may also carry the identification information of the service queue.

Step 44: The NodeB guarantees resources corresponding to the GBR information of the single service queue when the resources are allocated according to the GBR information.

Specifically, after receiving the data frame, the NodeB obtains the GBR information of the single service queue and the identification information of the service queue carried in the SPI field, which is carried in the GBR field of the data frame, and obtains the identifier information corresponding to the service queue. GBR information for a certain business queue.

The NodeB can obtain the GBR information corresponding to each of the multiple service queues by receiving the multiple data frames sent by the RNC.

Then, the RNC performs QoS control on the corresponding service queue according to the GBR information corresponding to the single service queue, and guarantees the resource corresponding to the GBR information corresponding to the single service queue when the resource is allocated.

For example, the bandwidth rate resource allocated by the NodeB is 100M, and the service queue 1, the service queue 2, and some other service queues are maintained on the network side. The GBR information for service queue 1 is 50M, and the GBR information for service queue 2 is 30M. Other service queues do not have corresponding GBR information.

Therefore, when the bandwidth resource is allocated, the NodeB first guarantees the bandwidth rate resource corresponding to the GBR information of the service queue 1 and the service queue 2, that is, allocates 50M to the service queue 1, allocates 30M to the service queue 2, and allocates the remaining 20M. Assigned to other business queues.

It can be seen from the technical solution provided by the foregoing embodiment of the present invention that the RNC sends a data frame carrying GBR information for a single service queue to the NodeB, and the NodeB can refer to the GBR information to different types of E-FACH users. The service allocates resources to guarantee the resources of the service queue corresponding to the GBR information. Therefore, the NodeB provides differentiated guarantees for different types of services of the E-FACH users, implements effective QoS control for the E-FACH users, and improves the satisfaction of the E-FACH users.
