Enhanced reliability of service in mobile networks
First Claim
1. A radio communications node in a first radio communications network operated by a primary public land mobile network (PLMN) operator to provide first radio communications service to first mobile user equipment terminals subscribed to the primary PLMN operator during a first normal mode of operation, the node comprising:
- radio circuitry configured to broadcast a primary radio network code associated with the primary PLMN operator which indicates that the first mobile user equipment terminals may obtain the first radio communications service provided from the primary PLMN operator; and
a receiver configured to receive an instruction to broadcast a standby radio network code,wherein a second different PLMN operator provides second radio communications service during the first normal mode of operation to second mobile user equipment terminals subscribed to the second PLMN operator,wherein the second mobile user equipment terminals are not allowed to obtain normal subscription service from the primary PLMN operator during the first normal mode of operation,wherein the receiver is configured, in response to the received instruction, to enter a standby mode of operation and to cause the radio circuitry to broadcast both the primary radio network code and the standby radio network code to permit one or more of the second mobile user equipment terminals to obtain the first radio communications service from the primary PLMN operator during the standby mode of operation.

Abstract
The technology described in this application increases the reliability of mobile networks. A radio communications node broadcasts a primary radio network code that indicates that subscribed mobile user equipment terminals may obtain service from a primary PLMN operator. In certain circumstances, the node may receive an instruction to broadcast a standby radio network code during a standby mode of operation. During the standby mode of operation, second mobile user equipment terminals that are not subscribed may obtain radio communications service from the primary PLMN operator.

10. A controller node configured to interact with a first radio communications network operated by a primary PLMN operator, the controller node operable to communicate with at least one radio communications node of the first radio communications network, the at least one radio communications node configured to broadcast a primary radio network code associated with the primary PLMN operator during a normal operational mode, the controller node comprising:
-
a communications interface adapted to send an instruction to the at least one radio communication node to enter a standby mode and to broadcast a standby radio network code, wherein the primary PLMN operator provides radio communications service during the normal operational mode to first mobile user equipment terminals that are primary PLMN operator subscribers, wherein a second PLMN operator provides radio communications service during the normal operational mode to second mobile user equipment terminals that are second PLMN operator subscribers, and wherein the second mobile user equipment terminals are excluded from obtaining the radio communications service of the primary PLMN operator during the normal operational mode but are allowed to access the radio communications service of the primary PLMN operator during the standby mode. - View Dependent Claims (11, 12, 13, 14)

15. A method of increasing reliability of access to a radio communications network for mobile user equipment terminals, the method comprising:
-
establishing a first primary radio network code associated with a first PLMN operator that provides radio communications service to first mobile user equipment terminals that are subscribed to the first PLMN operator, the first PLMN operator operating a first radio communications network; establishing a standby radio network code that is associated with the first PLMN operator and related to a second PLMN operator, the second PLMN operator providing radio communications service to second mobile user equipment terminals that are subscribed to the second radio communications operator, the second PLMN operator operating a second radio communications network; broadcasting the first primary radio network code; activating a standby mode; broadcasting the standby radio network code in response to activating the standby mode; denying normal subscription service to the first PLMN operator for the second mobile user equipment terminals when the standby mode is inactive; and providing service from the first PLMN operator for the second mobile user equipment terminals when the standby mode is active. - View Dependent Claims (16, 17, 18, 19, 20, 21)
