3GPP在2002年启动的R5版本中为GPRS/3G网络设计了基于IP传输之上的标准化的多媒体解决方案IMS,其方案内容包括安全功能、计费功能、漫游功能和服务质量(QoS)等。2004年的3GPP R6版本对该计费功能进一步完善,定义了一个独立的功能强大的计费体系。该体系主要采用两种计费机制:离线计费和在线计费。本文将对这两种计费机制的结构及各功能实体进行分析,简述其计费过程,并提出该计费体系存在的局限性以及以后可能的发展方向。 相似文献

The 3GPP network specification is currently undergoing major updates toward beyond 3G. The evolved 3GPP network will support interworking with multiple including non-3GPP - radio access networks, and support mobility between them. It will furthermore support personal area networks and moving networks. Generally, 3GPP is moving in the direction of an all-IP network. This article gives an overview of current beyond 3G trends in 3GPP, and particularly introduces a new 3GPP study item on network composition. The concept of network composition was developed by the EU project Ambient Networks. Whereas 3GPP until now assumes static networking relations, network composition addresses a dynamic, generic establishment of control-plane interworking between the heterogeneous network types of today, such as 3GPP core networks, non-3GPP operator networks, heterogeneous access networks, and personal area networks 相似文献

Since 2017, 3rd Generation Partnership Program (3GPP) is working on integration of satellite communication in 3GPP. This paper discusses the results of the work on service and network architecture aspects in 3GPP Technical Specification Group (TSG) Service and System Aspects (SA) and 3GPP TSG Core Networks and Terminals (CT). This paper does not discuss radio aspects as are specified in 3GPP TSG radio access network (RAN). 3GPP first specified requirements and use cases for satellite access. Subsequently, architecture and protocol specifications were created for integration scenarios, direct access, network selection, mobility management, and satellite backhaul with quality of service (QoS). Also, impacts of regulatory aspects on satellite integration have been discussed in 3GPP. With the completion of Release 17, 3GPP specifications are now ready for implementation of integrated 5G satellite networks. 3GPP will continue with further development of satellite integration in Release 18 and Release 19. 相似文献

The evolved packet system (EPS) integrates third generation partnership project (3GPP) and non-3GPP wireless access networks to provide mobile users with ubiquitous access to a diverse set of multimedia services. As we know, 3GPP and non-3GPP access networks differ significantly with respect to bandwidth capacity, coverage range, and service cost. It is crucial to enable efficient load balancing between 3GPP and non-3GPP access networks to improve resource utilization, and still maximize revenue generation. From an economic point of view, pricing plays an important role in achieving load balancing in the EPS. This paper proposes an access-aware pricing strategy for the EPS to achieve load balancing between 3GPP and non-3GPP access networks and to maximize revenue generation for network operators. In addition, this paper develops an analytical model for the system using the proposed access-aware pricing strategy. With the analytical model, this paper also proposes an iterative method for determining the optimal pricing that maximizes revenue generation in the EPS. The analytical model is verified by simulation. 相似文献
