Description

Paging method, device, system and storage medium

Technical field

The present invention relates to the field of communications, and in particular to a method, an apparatus, a system, and a storage medium for paging.

Background technique

Mobile communication has developed rapidly in more than 20 years, which has brought huge impacts on people's lifestyle, working methods, social and political, and economic aspects. Human society has entered an era of efficient informationization, and the demand for business applications in all aspects has exploded. It will bring huge challenges to the future wireless mobile bandwidth system in terms of frequency, technology and operation.

In addition to providing services for everyone's communication, the future mobile network will provide access services for more and more IoT terminals. Internet of Things access brings new challenges and opportunities to mobile networks. Different types of Internet of Things have different needs for the network. Some require the network to provide high real-time and high-reliability services, such as telemedicine, while others require regular small data transmission services, such as remote meter reading systems. For different business needs, mobile networks may need to be properly optimized to meet business needs. More and more Internet of Things puts more and more different optimization requirements on mobile networks. Some of the optimization requirements may be contradictory. Therefore, a converged core network is increasingly unable to meet various Internet of Things. demand.

With the advent of Network Function Virtualization (NFV), core network functions can be built on common hardware without the need for a dedicated hardware platform. The emergence of NFV makes it possible for operators to build different virtual core networks for different network business needs. The virtual core network built for different network business needs is called a network slice. Each network function in the virtual core network can be optimized and customized according to network service requirements. Network slices based on NFV technology can be rapidly deployed according to requirements to quickly meet the needs of different scenarios.

1 is a schematic diagram of a network slice in accordance with an embodiment of the present invention. In Figure 1, three network slices (network slices 1, 2, 3) are illustrated. A network slice forms a virtual core network, and provides a mobile network access service for a specific set of user equipment (User Equipment, UE for short). A typical network slice includes a set of virtualized core network functions, such as a Mobility Management Entity (MME) function and a Policy and Charging Rules Function (PCRF) function. The Home Subscriber Server (HSS) function, the Gateway Controller (GW-C) function, and the Charging Gateway (CG) function. The network slice is constructed by the operator according to the requirements and the operator policy. The function of a network slice is also determined by the operator according to the requirements and the operator policy. For example, some network slices may include dedicated forwarding in addition to the control plane function. Some network slices may only include some basic control plane functions, such as only the MME and the gateway controller, and other core network related functions are shared with other network slices.

In the related art, there is also a radio access network (Radio Access Network, RAN for short) sharing. According to the 4G protocol, when an eNB is simultaneously connected to multiple Public Land Mobile Networks (PLMNs), the mobility management entity CODE (referred to as MME CODE) of different PLMNs connected to the eNB must be planned as not Collision: That is, the MME CODE of the MMEs of different PLMNs connected to the eNB must be planned differently. This is because, in the case of service request and paging, only the temporary user identification code (SAE-Temporary Mobile Subscriber Identit, S-TMSI) is transmitted in the air interface, and the S-TMSI includes the MME CODE and the MME temporary user identifier ( MME-Temporary Mobile Subscriber Identity (M-TMSI), in order to enable the UE to be found during paging, the MME CODE of the MMEs belonging to different PLMNs cannot be the same, otherwise, in paging, one page will be paged to the same as the MME CODE attached. All UEs with the same M-TMSI on different MMEs, that is, UEs that should not wake up.

Using the above method to plan the MME CODE makes the network planning complicated, and the MME CODE has a total of 8 bits. If the MME CODE is used to distinguish the network slices, the total number of network slices that can be supported cannot be greater than 256, which limits the development of the network slice.

For the related art, how to distinguish the terminals in different network slices in the process of paging has no effective solution at present.
