Description

Bearer creation method, device and system

Technical field

The present invention belongs to the field of mobile communications, and in particular, to a bearer creation method, apparatus, and system.

Background technique

Evolved Packet System (English abbreviated as EPS) ), according to the quality of service (English name is Quality of Service, English abbreviated as QoS), EPS bearer ( Bear ) can be divided into two categories: guaranteed bit rate (English full name Guranteed Bit Rate, English abbreviated as GBR) and no guaranteed bit rate (English full name Non-Guranteed Bit Rate, English abbreviated as Non-GBR), the GBR , means that the bit rate required by the bearer is 'permanently' allocated by the network, and the corresponding bit rate can be kept constant even in the case of tight network resources; conversely, the Non-GBR It means that in the case of network congestion, the service (or bearer) needs to bear the requirement of reducing the rate. Among them, GBR also includes the maximum bit rate (English full name is Maximum Bit Rate) , English abbreviated as MBR), defined as the upper limit of the rate that GBR Bear can reach under sufficient resources. The value of MBR may be greater than or equal to the value of GBR. Due to Non - GBR bearers do not need to occupy fixed network resources and can be established for a long time. GBR bearers are generally only established when needed.

In addition, in order to improve the user experience and reduce the delay of business establishment, the user's 'permanent online' is realized in the EPS. The default bearer is introduced in the system (English name is Default Bearer). The concept of establishing a default bearer for a fixed data rate for the user while the user is booting up, ensuring that the basic service needs are established with the establishment of the PDN link, along with the PDN. The link is removed and destroyed, providing users with a permanent online IP transport service. The default bearer is a Non-GBR bearer. In general, each PDN connection corresponds to a default bearer and a IP Address. The quality of service QoS parameters of the default bearer can come from the home subscriber server (English full name Home Subscriber Server, English abbreviated as The contract data obtained in HSS) can also pass the policy and charging rules function (English abbreviation for Policy and Charging Rules Function, English full name PCRF) Change these values either interactively or based on local configuration.

User equipment for the same IP address (English name is User Equipment, English abbreviated as UE) Providing services with different QoS guarantees, such as video calls, mobile TVs, etc., need to be in the UE and public data network (English full name is Public Data Network, English abbreviated as One or more proprietary bearers (English full name Dedicated EPS Bear) are established between PDNs. Other EPS bearers connected to the same PDN are called proprietary bearers. Operators can use PCRF (Policy And Charging Resource Function) The defined policy maps different data flows to the corresponding proprietary bearers and uses different QoS mechanisms for different EPS Bears. The proprietary bearer can be a GBR bearer or a Non - GBR bearer. The creation or modification of a proprietary bearer can only be initiated by the network side, and the bearer QoS parameter values are always assigned by the packet core network.

With the increasing use of business applications in the mobile field, operators also carry out various package customization services for different users' diverse needs, and guarantee the bandwidth requirements of specific services according to user levels. For example, for paid customized users, it is necessary to create a dedicated bearer. To ensure the bandwidth of its business needs. The existing method of creating a bearer is through The PCRF sends a dynamic or predefined policy to the gateway GPRS support node (English name is Gateway GPRS Support Node, English abbreviated as GGSN). ) or the system architecture evolution gateway (English full name System Architecture Evolution Gateway, English abbreviated as SAE GW)) The way of the filter triggers the creation of a proprietary bearer to fulfill its GBR requirements.

However, due to the diversification of business applications, even if the same application, its filter information will change dynamically at any time, PCRF The filter information of the application service cannot be accurately configured, and according to the limitation of the standard protocol, one bearer corresponds to one traffic flow template (English full name) TFT), a communication traffic module currently allows up to 16 filters to be set, which cannot be adapted due to the diversity of applications. The requirements of diversity cannot effectively create corresponding proprietary bearers based on application information.

Since the application quality requirements vary from application to application, such as VOIP requiring low latency and low jitter, traditional FTP basically has only bandwidth requirements, while HDTV Both low latency and bandwidth requirements are required. This requires network devices to classify different services and assign different quality of service QoS to different service packets.

Protocol identification for business data, which may include NBAR (Network Based Application) Recognition ), or application layer-based flow control device Packetshaper, or use packet capture soft Ethereal and deep recognition detection technology DPI , can achieve the identification of the application layer protocol.

In step S102, the service quality QoS of the service data is obtained according to the preset matching rule of the QoS and the protocol. Information.

After the protocol identification of the service data, the quality of service required for the service data is required. Make settings. For different service data, it needs to match different bandwidth bearers or allocate bandwidth for it to realize monitoring of different services, and provide differentiated services for users while improving user experience.

Step S101 is performed by a preset service quality QoS and protocol matching rule. The protocol information identified in the match matches the corresponding quality of service information. For example, VOIP requires low latency and low jitter, while FTP basically has only bandwidth requirements, while HDTV Both low latency and bandwidth requirements are required, and different service quality QoS is assigned to different service packets.

In step S103, the quality of service QoS according to the service data Information, creating a corresponding bearer for the service data information.

For the obtained service quality information, the corresponding bearer needs to be matched for the corresponding service quality. Since the service quality generally involves the bandwidth and stability requirements, for the existing bearer, the default bearer is Non-GBR.

Therefore, the service type of the uplink dedicated bearer of a specific service type can be set, in the user equipment UE. After receiving the filter type information of the service type, the service type of the user equipment and the received filter filter Whether the information matches, if it matches, it indicates that it needs a dedicated bearer. If it does not match, it assigns a default bearer to transmit uplink message information. Therefore, the downlink service in the embodiment of the present invention creates a corresponding bearer by the protocol information of the downlink packet, and the uplink service can be the uplink packet and the uplink packet. Filter The matching condition is the default bearer or the dedicated bearer, which can support the requirements of different bearers for the uplink and downlink packets, so as to effectively ensure the bandwidth requirements of the following packets, and effectively save the bandwidth resources of the uplink packets.

In the embodiment of the present invention, the policy information including the quality of service delivered by the policy management network element is received, and after the received service data is identified, the corresponding service quality is matched according to the policy information, and the network element can be dynamically adjusted through the policy management network element. The service quality information of each service is obtained by searching for the service quality information of the existing bearer. If there is a dedicated bearer of the corresponding service quality, there is no need to create a new dedicated bearer. If there is no proprietary bearer of the corresponding quality of service, a new one is created. The dedicated bearer can further improve the transmission efficiency of the existing bearer. By matching the service type in the user equipment, the information of the uplink packet information and the small amount of information can be utilized to transmit some services through the default bearer, thereby improving network utilization. effectiveness.
