Problems solved by technology

[0004] However, when the UE is in the roaming state, it needs to try the PLMNs in the priority list one by one, which takes a lot of time and resources
In addition, the priority list in the USIM cannot be updated in time, causing the UE to make unnecessary access attempts to the network; even when the access request is accepted, the selected PLMN may not be the optimal roaming network, causing users To extra overhead, reduce user experience

Embodiment Construction

[0030] As mentioned in the background, in the prior art, when the UE is roaming, it needs to try the PLMNs in the priority list one by one, which consumes a lot of time and resources. In addition, the priority list in the USIM cannot be updated in time, causing the UE to make unnecessary access attempts to the network; even when the access request is accepted, the selected PLMN may not be the optimal roaming network, causing users To extra overhead, reduce user experience.

[0031] In the technical solution of the present invention, when the user equipment selects the PLMN to be accessed, it selects among the multiple PLMNs searched, and when the PLMN in the priority list is unavailable, the PLMN in the priority list can be avoided. Unnecessary access attempts. In addition, by sending the candidate network list to the network side, the PLMN to be accessed by the user equipment can be selected from the candidate network list, and the PLMNs in the candidate network list are ava...

Abstract

A network access method and device, user equipment and a base station are disclosed. The network access method includes: a plurality of available PLMNs are searched when no home PLMN and no registeredPLMN are available; a first PLMN among the plurality of searched PLMNs is selected for residing, a first access request for the first PLMN is sent to a network side, and a candidate network list is sent to the network side; the candidate network list includes the plurality of PLMNs. The network access method disclosed in the technical solution of the present invention can help optimize network access processes and improve access efficiency when no HPLMN / RPLMN is available.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a network access method, device, user equipment and base station. Background technique [0002] When the user equipment (User Equipment, UE) is in the automatic network selection mode, if the local public land mobile network (Home Public Land Mobile Network, HPLMN) / registered public land mobile network (Registered Public Land Mobile Network, RPLMN) is not available, it needs to be based on The PLMNs may be searched / selected in a priority order among Public Land Mobile Networks (PLMNs). [0003] In the prior art, the PLMN may be selected according to a priority list defined on a Universal Subscriber Identity Module (USIM). figure 1 It is a flow chart of network selection in the prior art. Such as figure 1 As shown, in step [1], the UE is in the automatic network selection mode, and can independently select the PLMN according to the definition of the communi...
