Method for transmitting service quality information in evolvement network

Abstract

The present invention discloses a method for delivering services quality in an LTE network, which is characterized in that: when an LTE wireless access network receives the services quality information, in the event the wireless network can not satisfy the current services quality demand, then by utilizing the services quality information received, through services quality information negotiation in or within labels; the services quality information negotiated already is returned back to the LTE PCN. In the LTE network, through the QoS negotiation mechanism of the invention, when the LTE network can not meet the current services quality demand, according to self resources conditions including resources availability and loading conditions etc., QoS parameters for the current services is renegotiated, ensuring the success rate of the UE services utilization, and improving the trust of the user.

Description

technical field [0001] The invention relates to an evolved network (Evolved Network) technology, in particular to a method for transmitting quality of service information in an evolved network. Background technique [0002] Currently, the 3rd Generation Partnership Project (3GPP) is studying the next-generation network after the evolution of the UMTS network, and formulating technical standards for the evolution network. In this paper, the evolution of the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) network The first generation network is referred to as the evolution network. The goal of the evolved network is to provide a low-latency, high data rate, high system capacity and coverage, low cost, and completely IP-based network. [0003] Figure 1 is a schematic structural diagram of a packet core network in an evolved network defined by 3GPP. As shown in Figure 1, the evolved network includes an evolved packet core network (E...

Problems solved by technology

[0015] At present, in the process of resource establishment and Qos signaling processing, only the QoS information that needs to be carried in the resource establishment process is given, but no specific implementation method is given for how to negotiate QoS information. In this way, the LTE-RAN functional entity cannot meet the requirements of receiving When the QoS information corresponds to the quality of service requirement, the LTE-RAN functional entity will give up the allocation of radio resources, which may interrupt the service currently requested by the UE and reduce the user's trust in the network

[0016] In addition, in the Evolved-RAN handover (HO) process of the evolved network, it is only proposed that QoS information needs to be transmitted in the handover request (HO request) message sent by the source eNodeB to the target eNodeB, and the specific QoS information transmitted The content, how to transfer and negotiate does not give a specific implementation method. In this way, the target eNodeB to which the UE is handed over may fail to meet the QoS requirements of the UE, which increases the probability of handover failure due to the inability to guarantee the quality of service. As a result, the service currently requested by the UE may be interrupted, reducing the user's trust in the network
