Abstract

A legitimate radio access network node may determine fake base station barring criteria that may be transmitted to a user equipment in a fake base station barring configuration. The user equipment may analyze information or signal characteristics corresponding to a signal associated with another node with respect to criteria contained in the fake base station barring configuration. The barring criteria may include a signal strength threshold or a timing advance threshold. If the analyzed information or signal characteristics satisfy barring criteria contained in the barring configuration, the user equipment may determine that the other node is a fake base station and may avoid selecting, or accessing, the other node. The user equipment may flush radio resource control configuration information corresponding to the fake base station. The user equipment may select or access a next-best node based on the barring criteria being satisfied with respect to the determined fake based station.

Claims (50)

1 . A method, comprising:

receiving, by a user equipment from a first radio access network node, a first fake base station barring configuration comprising at least one barring criterion;

receiving, by the user equipment from a second radio access network node, a signal;

analyzing, by the user equipment, the signal with respect to the at least one barring criterion to result in an analyzed signal;

receiving, by the user equipment from a third radio access network node, a second fake base station barring configuration;

determining, by the user equipment, that the first fake base station barring configuration and the second fake base station barring configuration are a same configuration; and

based on the analyzed signal being determined to satisfy the at least one barring criterion, facilitating, by the user equipment with respect to the second radio access network node, performance of a first communication action,

wherein the performance of the first communication action is based on the first fake base station barring configuration and the second fake base station barring configuration having been determined to be the same configuration.

2 . The method of claim 1 , wherein the at least one barring criterion comprises a signal strength coverage criterion.

3 . The method of claim 1 , wherein the at least one barring criterion comprises a timing advance criterion.

4 . The method of claim 1 , wherein the third radio access network node corresponds to a first signal strength, and wherein the configured communication action criterion specifies a connection, by the user equipment, to one of a set of radio access network nodes, wherein the user equipment determines that the set of radio access network nodes corresponds to a set of respective signal strengths above a configured signal strength threshold, wherein with respect to which the user equipment determines that the set of respective signal strengths corresponds to a strongest signal strength of the respective signal strengths, and wherein the method further comprises: initiating, by the user equipment, establishing a connection with a fifth radio access network node that corresponds to a second signal strength that is less strong than the first signal strength.

5 . The method of claim 1 , wherein the first fake base station barring configuration is received from the first radio access network node via a radio resource control release message.

6 . The method of claim 1 , wherein the first fake base station barring configuration is received from the first radio access network node via a system information block message.

7 . The method of claim 1 , further comprising:

based on the first fake base station barring configuration and the second fake base station barring configuration having been determined to be the same configuration, overriding, with the first fake base station barring configuration by the user equipment, a third fake base station barring configuration, wherein the user equipment received the third fake base station barring configuration before receiving the first fake base station barring configuration or the second fake base station barring configuration.

8 . The method of claim 1 , further comprising:

receiving, by the user equipment from a fourth radio access network node, a third fake base station barring configuration;

determining, by the user equipment, that the first fake base station barring configuration and the third fake base station barring configuration are different configurations; and

based on the first fake base station barring configuration and the third fake base station barring configuration having been determined to be different; avoiding, by the user equipment, operation with respect to the fourth radio access network node according to the third fake base station barring configuration.

9 . The method of claim 1 , wherein the at least one barring criterion comprises an identifier corresponding to the second radio access network node, and wherein the communication action comprises avoiding selecting the second radio access network node.

10 . A user equipment, comprising:

at least one processor configured to:

select a first radio access network node according to a configured selection criterion;

receive, from the first radio access network node, a fake base station barring configuration comprising at least one barring criterion;

determine a second radio access network node to be selected according to the configured selection criterion;

analyze at least one measured parameter value, corresponding to the second radio access network node, with respect to the at least one barring criterion to result in at least one analyzed measured parameter value;

determine that the at least one analyzed measured parameter value satisfies the at least one barring criterion

based on the at least one analyzed measured parameter value being determined to satisfy the at least one barring criterion, avoid selecting the second radio access network node based on the at least one analyzed measured parameter value being determined to satisfy the at least one barring criterion;

wherein the at least one measured parameter value, corresponding to the second radio access network node, is at least one first measured parameter value, wherein the at least one analyzed measured parameter value comprises a first analyzed parameter value, and wherein the at least one processor is further configured to:

determine a third radio access network node to be selected according to the configured selection criterion;

analyze at least one second measured parameter value, corresponding to the third radio access network node, with respect to the at least one barring criterion to result in at least one second analyzed measured parameter value; and

based on the at least one second analyzed measured parameter value being determined not to satisfy the at least one barring criterion, select the third radio access network node.

11 . The user equipment of claim 10 , wherein the at least one processor is further configured to:

establish, with the third radio access network node, a communication session; and

transmit, to the third radio access network node, an identifier corresponding to the second radio access network node to be usable by the third radio access network node to facilitate updating the fake base station barring configuration to result in an updated fake base station barring configuration that comprises an indication that the second radio access network node is a barred fake base station.

12 . A non-transitory machine-readable medium, comprising executable instructions that, when executed by at least one processor of a user equipment, facilitate performance of operations, comprising:

receiving, from a first radio access network node, a fake base station barring configuration comprising at least one barring criterion;

receiving, from a second radio access network node, a broadcast signal;

analyzing, at least one signal characteristic corresponding to the broadcast signal with respect to the at least one barring criterion to result in an analyzed signal characteristic; and
