Problems solved by technology

At some point, due to some reasons, an operator has a network failure, for example, the S1 link from the RAN to the MME (Mobility Management Entity, Mobility Management Entity) is broken, see figure 1 As shown, due to the lack of corresponding solutions at present, it will lead to abnormal phenomena such as UE (User Equipment, User Equipment) still trying to access the faulty operator, causing adverse effects

Embodiment 1

[0076] figure 2 It is an exemplary flow chart of a method in Embodiment 1 of the present invention. In order to solve the above problems, this embodiment provides a fault handling method in an operator-shared network, which is used for a first base station, and multiple operators share a network under the first base station, and the method includes:

[0077] S201. Obtain an identifier of a faulty operator, where the faulty operator is an operator under the first base station where a network fault occurs;

[0078] S202. Notify the UE under the first base station of the identity of the faulty operator through a specified message, so that the UE under the first base station no longer accesses the faulty operator under the first base station network; wherein, the designated message includes the identification of the faulty operator.

[0079] In this embodiment, preferably, the designated message may be a SIB message, and the cell barred field of the SIB message includes a list ...

Embodiment 2

[0089] image 3 It is a schematic diagram of signaling of the method in Embodiment 2 of the present invention. This embodiment is based on the first embodiment and is a further refinement of the first embodiment.

[0090] In the prior art, some fields of the SIB message broadcast by the base station can be seen in Table 1 below, where the cellBarred (cell barred) field is used to indicate whether the current cell is barred from access. If the operator of the cell fails, the UE can no longer access according to the cellBarred field.

[0091] Table 1

[0092]

[0093] However, the inventor found in the process of implementing the present invention that the above method is applicable to only one operator under the first base station, because at this time, it can be deduced that the cell cannot be accessed if the operator fails. However, when the first base station When there are multiple operators, this method has limitations, because the failure of one operator does not me...

Embodiment 3

[0108] This embodiment is based on the foregoing embodiments, and is a further expansion and improvement of the foregoing embodiments. In the above embodiment, the first base station can inform the UEs in its cell which operators have link failures through the extended SIB message, thereby avoiding UE access errors and solving the basic problem when failures occur in the shared network of operators. question. In this embodiment, the faulty base station (that is, the first base station) can further notify the adjacent base station (that is, the second base station) of the operator's failure information, so that the adjacent base station can respond accordingly, so that the fault handling mechanism is more complete .

[0109] Specifically, in this embodiment, for the first base station, the method may further include:

[0110] After getting the id of the faulty operator:

[0111] Notifying the identity of the faulty operator to a second base station adjacent to the first base...

Abstract

A method and an apparatus for processing a fault in a multi-operator core network are disclosed. The method is applied to a first base station, where multiple operators share a network within coverage of the first base station, and the method includes: acquiring an identifier of a faulty operator, where the faulty operator is an operator whose network is faulty within coverage of the first base station; and notifying UE served by the first base station of the identifier of the faulty operator by using a specified message, so that the UE served by the first base station no longer accesses the network of the faulty operator within coverage of the first base station. In a scenario in which multiple operators share a network within coverage of a base station, when a network of one operator is faulty or networks of some operators are faulty (for example, an S1 link is faulty), in the present invention, UE served by the base station may be notified of an identifier of the faulty operator by using a specified message (such as a SIB message), so that the UE correctly determines which operators have a network fault, thereby avoiding an abnormal phenomenon such as a phenomenon that the UE still attempts to access the network of the faulty operator.

Description

technical field [0001] The invention relates to a network sharing technology in network communication, in particular to a fault handling method and device in an operator's shared network. Background technique [0002] Network sharing technology (Network sharing) can enable multiple operators (Operator) to provide services to their respective users through a shared mobile network, thereby greatly reducing the cost of repeated construction of mobile networks. But while this kind of sharing has many advantages, it also often increases the complexity of the network, especially when the network fails, it is more difficult to deal with. [0003] A typical scenario is that there are services provided by multiple operators in a cell (Cell) covered by a base station, and the network of these operators in the cell can be called the operator's PLMN (Public Land Mobile Network, Public land mobile network), the PLMN of each operator shares the RAN (Radio Access Network, shared radio acc...
