随着高铁GSM-R通信网络的迅猛发展,网上用户容量也越来越大,而共享资源逐渐成为瓶颈,需要为VIP铁路部门提供更好的服务,优先保证资源。就是为不同用户提供不同等级的服务。对优先级高的用户,提供较高的服务质量;对优先级低的用户,提供较低的服务质量。通过定义优先级,实现对不同优先级的用户在资源的预留、使用、抢占,以及业务的服务质量给予不同的服务策略。特别是在网络资源比较紧张的情况下,eMLPP业务就显得非常重要,可以帮助GSM-R系统满足优先客户的业务需求。
With the rapid development of high-speed rail GSM-R communication network, the capacity of users on the Internet is also getting larger and larger, and sharing of resources has gradually become a bottleneck. It is necessary to provide better service to VIP railway departments and give priority to ensuring resources. Is for different users with different levels of service. For high priority users, to provide higher quality of service; for low priority users, to provide lower quality of service. By defining priorities, different service strategies are given to reserving, using, preempting, and service quality of users with different priorities. Especially in the case of relatively tight network resources, eMLPP business is very important, can help GSM-R system to meet the priority customer’s business needs.
