The application provides an inter-network subscription signaling topology hiding method, a restoring method, a device and a medium, relates to the technical field of communication, and is used for solving the problem that the prior art lacks a scheme for hiding the topology of the local network lNRF network element in the inter-network subscription signaling, which may cause the sensitive information of the local network to be leaked to the foreign network. The hiding method comprises the following steps: receiving a first inter-network subscription signaling from the local network; obtaining the real address of the local network local network registration function lNRF network element from the first inter-network subscription signaling; performing topology hiding on the real address of the local network lNRF network element to obtain a hidden address of the local network lNRF network element; replacing the real address of the local network lNRF network element in the first inter-network subscription signaling with the hidden address of the local network lNRF network element to obtain a second inter-network subscription signaling; and sending the second inter-network subscription signaling to the foreign network. The application avoids the real address of the local network lNRF network element that needs to be kept secret from being leaked to the foreign network, and ensures the safety of the information of the local network.

A lost or stolen mobile electronic device may attempt to attach to a foreign network where the phone is not blocklisted. During the foreign network / roaming attach process, a location update may be sent to the home network. The location update may include identifying information for the device. A mapping of the device and the foreign network's association may be stored within an operator database at the home network. Once the lost or stolen phone authenticates with an access point (AP), the mobile device may associate or register with the AP to gain full access to the foreign MNO. The lost or stolen phone may send an Association Request including updated location information and the phone's identification to the phone's home network. If the mapping does not include the phone's identification and the requesting foreign network, then the home network will deny the association request.

The application provides a topology hiding method, a topology restoring method, a device, a medium and a PLMN, and relates to the field of communication, and is used for solving the problem that the real topology information of the network may be leaked in the prior art. The topology hiding method comprises the following steps: obtaining real topology information of the network in first signaling to be sent to a foreign network; encrypting the real topology information of the network by using a preset first key to obtain encrypted topology information of the network; combining the encrypted topology information of the network and a first key identifier SKID to obtain hidden topology information of the network; replacing the real topology information of the network in the first signaling with the hidden topology information of the network to obtain second signaling; and sending the second signaling to the foreign network. The application realizes that the signaling sent to the foreign network does not expose the real topology information of the network, and the information of the key cannot be obtained by the foreign network, so that the foreign network cannot analyze the real topology information of the network, and the safety of the real topology information of the network is ensured.

The application discloses a kind of different network roaming area opening method, device, equipment, storage medium and product, applied to wireless communication technical field, the method includes: by the grid model of target area is constructed by carrying out grid division according to scene type to target area;According to the network opening influence data of each grid in the grid model, different network roaming opening decision is made to each grid;In at least one grid, the opening instruction is sent to at least one target communication service provider in the case where different network roaming needs to be opened;Wherein, the opening instruction is used to indicate that at least one grid is opened roaming service by the target communication service provider;The present application can realize the meter-level precision opening of different network roaming area, break through the traditional area extensive opening mode, effectively solve the problem of opening range inaccuracy, resource waste, so as to improve resource allocation efficiency and network service quality.

The application provides a kind of identification and processing method and system for overseas network attack threat intelligence, specifically applied in text processing field, comprising: collecting new page, obtaining multiple structured text data using multiple analysis engines;After merging, obtain new intelligence records;Using intelligence quality evaluation algorithm to score new intelligence records, get the score results;Add new intelligence records and corresponding score results to intelligence database;Further generate daily briefing and update search engine index.

The present disclosure discloses a method and device for identifying the position of a foreign network base station, electronic equipment and a storage medium. Target measurement report data is obtained. A density clustering algorithm is called to cluster the target measurement report data, and at least three target clusters of foreign network adjacent areas are obtained. The target clusters are calculated to obtain first position information of the optimal network signal and second position information of the worst network signal of the target clusters. The first center position of the optimal network signal set and the second center position of the worst network signal set of the at least three foreign network adjacent areas are calculated respectively. The signal source direction line composed of the second center position pointing to the first center position in each foreign network adjacent area is determined. The intersection area is constructed through at least three signal source direction lines, and the center position information of the intersection area is determined. The center position is determined as the position of the target foreign network base station. The present disclosure is suitable for complex communication environment, reduces the limitations of foreign network base station position identification, and can accurately identify the position of the foreign network base station.
