Embodiment Construction

[0120] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0121] see Figure 1a , Figure 1a is a schematic diagram of the network structure provided by the embodiment of the present invention, such as Figure 1a As shown, UE11, a first RAN node 12, a second RAN node 13 and a core network node 14 are included. Among them, the UE11 can be a mobile phone, a tablet computer (TabletPersonal Computer), a laptop computer (LaptopComputer), a personal digital assistant (personal digital assistant, PDA for short), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device) and other terminal equipment, the specific type of UE11 is not limited in the embodiment of the present invention. Wherein, the above-mentioned first RAN node 12 may be a RAN node of the first RAN, such as a base stat...

Abstract

The present invention provides a network access method, related equipment and system, which may include: the UE saves the identification information of the network node accessed by the first RAN; sending a connection establishment request, where the connection establishment request includes the identification information of the network node, so that the second RAN selects the network node for the UE as the network node that the UE accesses in the second RAN . The embodiment of the present invention can realize that the UE camps on the network through two RANs at the same time.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a network access method, related equipment and system. Background technique [0002] At present, the core network in the mobile communication system only allows access to the radio access network (RAN, Radio Access Network) of the Long Term Evolution (LTE, Long Term Evolution) network, and the RAN of the 2G / 3G network cannot access the core network, that is, the user terminal ( UE, User Equipment) can only choose to reside on the LTE network or the 2G / 3G network at the same time. However, with the development of communication technology, there may be scenarios in the future that require UE to reside in the network through two RANs at the same time. For example, in 5G, it is necessary to support the scenario where UE accesses the network through multiple access systems. It can be seen that at present, UE resides in the network through two RANs at the same time, whi...
