In the flat network architecture, the bearer service is divided into two parts: a radio bearer service (Radio Bearer Service, hereinafter referred to as RBS) and an access bearer service (Access Bearer Service, hereinafter referred to as ABS). In the embodiment of the present invention, for the flat networking architecture, the QoS mapping of the Bearer Service to the access bearer service is implemented, and various factors can be comprehensively considered in the mapping process to obtain an accurate service transmission QoS value. Thereby achieving reliable QoS control in the network. The corresponding bearer service may specifically be a UMTS bearer service, or may be another bearer service, such as SAE (System Architecture Evolution) or LTE (Long Term Evolution). Hosting services, etc.

Further, in the flat networking architecture, the service is carried according to the service type, the service processing priority, and the allocation/holding priority in the bearer service attribute, or according to the service type and the allocation/holding priority in the bearer service attribute. Attribute mapping to the access bearer service ABS attribute, BP: determining the users of different priority types, in the process of carrying out services of different service types, specifically corresponding transmission service quality parameters (or transmission service quality types), so that The corresponding transport service quality is controlled in the access bearer network of the flat networking architecture.

Correspondingly, in the flat networking architecture, the mapping of the corresponding bearer service attribute to the radio bearer service RBS attribute may be further included, so as to facilitate the transmission of the radio bearer network in the flat networking architecture according to the corresponding radio bearer service RBS attribute. Quality of service is controlled.

Through the above process, when a specific bearer service needs to be established at the upper layer, the corresponding mapping can be implemented through negotiation or pre-configuration, thereby implementing the corresponding transmission service quality of the access bearer network and/or the radio bearer network. control.

In the process of mapping the bearer service attribute to the radio bearer service RBS attribute, the radio access bearer service attribute in the traditional UMTS network may be used as the radio bearer service attribute. The process of mapping the bearer service attribute to the access bearer service ABS attribute may be: determining the access bearer service attribute according to parameters such as a service type, a service processing priority, and an allocation/holding priority in the bearer service attribute.

In the embodiment of the present invention, the radio resource provided by the radio access device is managed according to the radio bearer service RBS attribute in the radio access device (such as a base station, etc.), and the service for the radio bearer of the access user is implemented. Quality is controlled.

And managing the resource between the gateway device and the management device (such as the SGSN) according to the access bearer service ABS attribute on the gateway device (such as the GGSN), and managing the device and the wireless device according to the access bearer service attribute on the management device The resources between the ingress devices are managed to implement the quality of service control for the access bearer of the access user; or directly on the gateway device (such as the GGSN or the serving gateway, etc.) according to the access bearer service ABS attribute to the gateway device and The resources between the wireless access devices are managed without the participation of the management device (such as the SGSN or the mobile performance management entity MME) to implement the quality of service control for the access bearer of the access user.

The embodiment of the present invention can be specifically applied to the direct tunnel mode in the flat networking architecture, and can also be used in the indirect tunnel mode. For example, in a flat UMTS network, the mode of transmitting the user plane service between the eHSPA NodeB and the GGSN may specifically include a direct tunnel mode and an indirect tunnel mode, where:

In direct tunnel mode, as shown in Figure 2, eHSPA (Evolved HSPA, evolved HSPA) NodeB and GGSN establish a direct tunnel to transfer user plane data, that is, directly through Gn-UP (Gn User Plane, Gn interface user plane) In the indirect tunnel mode, as shown in Figure 3, the user plane service between the eHSPA NodeB and the GGSN is performed through the tunnel between the eHSPA and the SGSN and the tunnel between the SGSN and the GGSN (two tunnels in total). Transmit, that is, the user plane service is transmitted through the Iu-PS UP interface and the Gn UP interface. On the control plane, the eHSPA NodeB is connected to the SGSN via the Iu-PS CP interface.

As shown in Figure 4, the UMTS bearer service is also divided into two parts: UMTS Radio Bearer Service and UMTS Access Bearer Service. In the direct tunnel mode, the UMTS access bearer service does not need to be forwarded through the SGSN.

Under the flat networking architecture, the QoS attributes of the corresponding UMTS radio bearer service part can inherit the wireless access inheritance of the traditional architecture. The QoS attribute of the service, that is, the mapping of the UMTS bearer service attribute to the UMTS radio bearer service attribute, is the same as the mapping mechanism of the UMTS bearer service attribute to the radio access bearer service attribute in the legacy network. Moreover, since the RNC function has been moved down to the base station NodeB in the flat networking architecture, that is, the Iub interface transmission under the traditional architecture is omitted, the flat networking architecture can shorten the delay of the radio access bearer portion.

In the flat networking architecture, the corresponding UMTS access bearer service part, in addition to inheriting the traditional architecture CN bearer service, also adds the access network part of the traditional architecture terrestrial transmission. That is, the UMTS access bearer service needs to support the CN bearer service function of the traditional architecture, and together with the physical bearer service, provides a transport service between the eHSPA NodeB and the GGSN (if it is an indirect tunnel mode, and also includes the SGSN). The QoS control mode of the corresponding UMTS access bearer service adopts FR QoS (Frame Relay based quality of service), IP QoS (IP based quality of service) or ATM QoS (ATM based quality of service), etc. The QoS control mode is determined by the type of service network selected by the operator.

For mobile operators, because the geographical location of the base station is dispersed, the transmission resources of the last mile are the most scarce. Therefore, when the wireless air interface rate is rapidly increased, the transmission bandwidth resource of the UMTS access bearer service will become the operator's deployment of the UMTS network. A serious challenge. Therefore, the transmission resources between the eHSPA NodeB and the GGSN in the corresponding direct tunnel mode, and the transmission resources between the eHSPA NodeB and the SGSN in the indirect tunnel mode will become scarce resources, and the UMTS bearer layer maps the service QoS to the UMTS. When accessing the bearer service QoS, in addition to inheriting the CN bearer attribute value of the traditional architecture, the UMTS access bearer layer QoS needs to introduce corresponding consideration factors for different services.

UMTS can carry a wide variety of business applications. 3GPP divides the service categories into four categories: Conversational class, Streaming class, Interactive class, and Background class. There are different QoS requirements depending on the application. For example, voice services (belonging to the conversation class) require low latency and low jitter, while the email service is not sensitive to delay. The UMTS bearer service attributes can be set according to the service characteristics. For interactive services, THP (Traffic Handling Priority) needs to be considered. For these four services specified by 3GPP, ARP (Allocation/Retention Priority) and TC (Traffic Type) need to be considered. So that the operator can dynamically and flexibly allocate scarce transmission resources based on user priority (ARP corresponds to the corresponding user priority) and service category (ie, TC) to maximize revenue.

Under the corresponding flat architecture, the UMTS access bearer service QoS attribute (that is, the upper layer UMTS bearer attribute is mapped to the lower layer UMTS access bearer service attribute) as shown in Table 1:

Indication Correspondingly, the mapping according to the UMTS bearer service attribute TC (service type), THP and/or ARP value to the lower layer UMTS radio bearer and UMTS access bearer service attribute value is as shown in FIG. 5. The UMTS access bearer service attribute is a transmission QoS value obtained by considering a parameter such as TC, THP, and/or ARP value. In addition, as described above, the mapping of the UMTS bearer service attribute to the UMTS radio bearer service attribute may be the same as the mapping mechanism of the UMTS bearer service attribute to the radio access bearer service attribute in the legacy network.

A specific example will be given below. After comprehensively considering TC, THP and ARP in the application embodiment, the mapping mechanism of the UMTS bearer service attribute value to the transmission QoS parameter indicating the access bearer service attribute is implemented as shown in FIG. 6. That is, according to the Traffic class (ie TC), THP, ARP value, etc. in Table 1, the transmission QoS is mapped to the transport layer. When the transmission network adopts ATM (Asynchronous Transfer Mode), the corresponding transmission QoS parameters (ie, ATM QoS) may include: CBR (Constant Bit Rate), RT-VBR (Real-time Variable) Bit Rate, real-time variable bit rate), NRT-VBR (Non-Real-Time Variable Bit Rate) and UBR (Unspecified Bit Rate) are four priority levels; When using IP transmission, the corresponding transmission QoS (ie IP QoS) parameters can include: EF (Expedited Forwarding), AF4 (AF, assured forwarding, guaranteed forwarding), AF3, AF2, AF1 and BE (Best Effort, best effort) And) six priorities.

Referring to FIG. 6, the corresponding mapping process of the UMTS bearer service attribute value to the transport QoS parameter indicating the access bearer service attribute may specifically include:

Step 1, according to the pre-defined allocation/holding priority ARP and the user priority User-Priority information, obtain the User-Priority of the user;

Referring to Table 2, the corresponding user priorities can be, but are not limited to, three levels of gold, silver, and copper, and are represented by 1, 2, and 3, respectively, as shown in Table 2 below:

Table 2

ARP 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

User—Priority erro 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 r It is understandable that ARP can also be used directly to represent the user's priority.

Step 2: According to a mapping mechanism of a predefined TC, a user priority, and a transmission QoS, the mapping obtains a transmission QoS corresponding to a service type of the user _; The corresponding mapping mechanism may specifically but not limited to the following Table 3:

table 3

In this step, for the session, flow, and background services specified by the 3GPP, the transmission QoS corresponding to the corresponding service type of the user may be directly obtained according to the information in Table 3 through the corresponding TC and User Priority. In addition, according to the use of ATM transmission or IP transmission, the mapping relationship shown in Table 3 is different.

For the interactive business, as mentioned above, the business processing priority THP needs to be considered. ΒΡ, according to the information in Table 3, the corresponding TC, User Priority, and THP are mapped to obtain the transmission QoS corresponding to the interactive service of the user. same, The mapping relationship shown in Table 3 differs depending on the use of ATM transmission or IP transmission.

Of course, if ARP is used to represent the priority of the user, the mapping relationship in Table 3 can be slightly adjusted.

Step 3: The corresponding transmission QoS is transmitted to the transport layer, and the transport layer performs transmission QoS control on the corresponding service type of the user according to the transport QoS.

It can be seen that in the QoS attribute of the UMTS access bearer service obtained by the above mapping, TC, ARP (or user priority User-Priority obtained by ARP), or TC, ARP (or obtained by ARP) are comprehensively considered. In addition to ensuring the QoS of the service, the user priority of the user priority and the fairness of the resource allocation can be well reflected, so that the operator can utilize the limited Transmission resources provide reasonable differentiated services for different users, which in turn provides a basic guarantee for operators to maximize revenue.

To facilitate the understanding of the embodiments of the present invention, the specific application of the embodiments of the present invention will be described below with reference to the accompanying drawings.

The use of the corresponding QoS mapping mechanism to implement the QoS comprehensive negotiation mechanism in the flat UMTS network is the main mechanism to ensure the bearer management, user management, admission control mechanism and effective network resource utilization of the UMTS network implementation control layer.

Referring to FIG. 4, according to different modes adopted by the flattened UMTS, the complete QoS negotiation process of the corresponding user terminal to the GGSN includes:

(i) Direct tunnel mode

In the direct tunnel mode, the corresponding complete QoS negotiation process includes:

After the eHSPA NodeB obtains the UE (User Equipment) service request, the eHSPA NodeB and the UE may determine a unique transmission QoS parameter for a specific service type of the user according to the mapped UMTS radio bearer service attribute, and then The transmission QoS parameter can be transmitted to the transport layer, so that the transport layer performs corresponding QoS control according to the corresponding QoS parameter, and the specific mapping can obtain the wireless connection in the traditional UMTS network in the process of obtaining the UMTS radio bearer service attribute. The inbound service attribute is used as the UMTS radio bearer service attribute. Between the eHSPA NodeB and the GGSN, the QoS control is performed according to the mapped UMTS access bearer service attribute. The process of obtaining the UMTS access bearer service attribute by using the specific mapping is shown in Table 2 and Table 3, or may be adopted. Other mapping implementations.

In summary, the UMTS radio bearer service attribute may be controlled and managed on the eHSPA NodeB according to the UMTS radio bearer service attribute to implement corresponding QoS control; and, specifically, the GGSN may be configured according to the UMTS access bearer service attribute. The resources between the eHSPA NodeB are controlled and managed to implement corresponding QoS control. The corresponding QoS control may be implemented by using a polling queue, or may be implemented by using a priority queue.

(ii) Indirect tunnel mode

In the indirect tunnel mode, the corresponding complete QoS negotiation process includes:

After the eHSPA NodeB obtains the UE's request for service, the QoS control is performed between the eHSPA NodeB and the UE according to the mapped UMTS radio bearer service attribute, and between the eHSPA NodeB and the SGSN, and between the SGSN and the GGSN according to the mapping. The UMTS access bearer service attribute is used for QoS control.
