Abstract: Embodiments of the present invention provide a requirement management method and apparatus. The method mainly includes: dividing all requirements of a system into layers from top to bottom according to a service object, a value and granularity of every requirement; obtaining a direct progress rate of any requirement in the system; obtaining direct progress rates of all lower-layer requirements of the any requirement; and calculating a mean of direct progress rates of all the lower-layer requirements to obtain a verification progress rate of the any requirement, and performing a weighting operation on the direct progress rate and the verification progress rate of the any requirement to obtain a progress rate of the any requirement.

Abstract: The present invention discloses a method for handling an emergency service in a network communication, including: sending, by an emergency service initiating side, an emergency service identifier together with an emergency service to a network side; and allocating, by the network side, resource to the emergency service with a priority higher than those of normal services. With the present invention, a corresponding emergency service may be identified effectively in a network provided with an independent bearer-control-layer entity, and a resource may be allocated to the emergency service in accordance with a special resource allocation policy. Therefore, it is possible to guarantee the connectivity and the resource for the emergency service as requested in the network, and hence to reduce an unexpected and unnecessary loss.

Abstract: The present invention discloses a method for handling an emergency service in a network communication, including: sending, by an emergency service initiating side, an emergency service identifier together with the emergency service to a network side; and allocating, by the network side, resource to a received service firstly when determining that the received service is an emergency service in accordance with the emergency service identifier. With the present invention, a corresponding emergency service may be identified effectively in a network provided with an independent bearer-control-layer entity, and a resource may be allocated to the emergency service in accordance with a special resource allocation policy. Therefore, it is possible to guarantee the connectivity and the resource for the emergency service as requested in the network, and hence to reduce an unexpected and unnecessary loss.

Abstract: A method and a system for intercommunicating between a private network user and a network with QoS guarantee are provided. The bearer control layer entity and the application layer entity obtain the address (port) translation information in the network with independent bearer control layer, and then allocate the resources for the private network user based on the address (port) translation information. According to the present invention, the various function entities may process transmission and translation of the private addresses correctly and hence accomplish a correct addressing and resource allocation. Thus, the problems that the end-to-end QoS resource allocation cannot be accomplished and the end-to-end QoS cannot be guaranteed when the user uses a private address are solved.

Abstract: Embodiments of the present invention disclose a method for guaranteeing end-to-end Quality of Service (QoS), including: establishing in advance a corresponding logic bearer layer for each network, and storing information of the logic bearer layer in a bearer control entity of the bearer control layer of each network; initiating a service request from a first user terminal to a first network, requiring to set up a service session with a second user terminal of a second network; both the bearer control entities of the first network and the second network allocating service paths and bandwidth resources within logic bearer layers and upon boundary exits of their own, respectively; based on the paths allocated by the bearer control entities of the first network and the second network, transmitting service stream between the logic bearer layers of these two networks.
