The scheme provided by the invention is based on the next generation 5G network architecture and considers the integration of access network and core network. At least some network elements in the core network are moved down to the access network. Considering the uRLLC scenario, in order to reduce the end-to-end delay and satisfy the reliability of data transmission, some network elements of the core network (such as GW including S/P_GW) are moved down to the access network, so that the access network will have independent IP address management and allocation capabilities as well as routing functions, but the downward movement of GW has a direct impact. Its IP address pool management will be different from the traditional LTE network. The main difference is that the next generation of 5G network based on NFV / SDN will dynamically create each slice network. Because the slice network in the access network needs to be created and deleted in real time according to needs, the impact is that the elements in each slice network will be created and deleted according to needs. Therefore, the allocation of IP address pool in GW will be dynamically managed according to needs, including dynamic creation, dynamic allocation, adjustment and recycling. The proposal of the invention is based on the above structure, and proposes a solution.

技术介绍
随着无线通信从传统的实时语音业务转变为现在的数据业务,无线通信系统接入的终端的数目以及传输速率均以几何级数增长。为了满足无线通信爆炸式的需求,下一代5G通信网络相比于当前的4G,需要支持更加广泛的业务类型和提供更好的覆盖和高质量的服务,如更大的传输速率和更低的端到端的时延。面对各种业务类型的不同的需求,下一代的5G网络将所有的业务类型主要划归为三类应用场景:第一种是面向大流量大带宽的演进性的移动宽带eMBB(evolvedmobilebroadband);第二种称为极低时延uRLLC(ultrareliablelowlatencycommunication),主要面向自动驾驶以及工厂流水线控制等业务;第三种是面向物联网拥有海量传感器的业务,称为mMTC(massivemachinetypecommunications)。为了同时支持以上不同种业务的需要,5G将采用基于NFV/SDN(networkfunctionvirtualization,Softwaredefinednetwork)等技术的切片网络。所谓切片网络,即是逻辑上相对独立的逻辑子网络。各子切片基于NFV/SDN技术运行在同一硬件平台,但各切片相互独立。根据用户的需求,各切片将有独立的生命周期,服务等级(Qualityofservice,QoS)保障机制,安全以及SLA(Servicelevelagreement服务等级协议)等等。在5G系统中,针对uRLLC业务, ...
