Various communication systems may benefit from suitable interworking. For example, certain fifth generation short message service systems may benefit from interworking with long term evolution short message service deployments in a visited public land mobile network. A method can include receiving, at a network element, an attach request from a user equipment. The method can also include using an internal policy to find a short message service function that resides at the network element. The method can further include using an address of the short message service function for providing short message service to the user equipment.

A data transfer method includes that a first device displays a first interface. The first interface includes image information of a first file. When a distance between a Near-Field Communication (NFC) chip of the first device and an electronic tag of a second device is less than a preset threshold, the first device obtains a BLUETOOTH address of the second device. The electronic tag includes device information of the second device, and the device information includes the BLUETOOTH address or a tag identifier (ID) used to obtain the BLUETOOTH address. The first device exchanges a WI-FI connection parameter with the second device through a BLUETOOTH connection corresponding to the BLUETOOTH address. The first device establishes a WI-FI connection to the second device. After the WI-FI connection is established, the first device automatically transfers the first file to the second device through the WI-FI connection.

A method performed in a network node for identifying UEs which are non-compliant with modified CRS operation. The network node enables CRS operation according to a first configuration for a first period. The network node analyzes Information Elements (IE) in RRC Connection Re-establishment Request messages received from UEs during the first period. The network node generates a first set containing identities of UEs whose values in reestablishmentCause IE in the RRC Connection Re-establishment Request messages received during the first period are “otherFailure”. When the first period is finished, the network node enables CRS operation according a second configuration different from the first configuration for a second period. The network node analyzes IE in RRC Reestablishment Request messages received from UEs during the second period. The network node generates a set containing identities of non-compliant UEs based on the first set and analyzing IE in the RRC Reestablishment Request messages received during the second period.

An electronic device includes a display; a first wireless communication circuit configured to support Bluetooth (BT) communication and to include a first BT address; a processor operatively connected to the display and the first wireless communication circuit; and a memory, wherein the memory may store instructions that are configured to, when executed, cause the processor to: receive first data including a second BT address associated with a first external device; perform a page scan based on the first BT address and the second BT address using the BT communication; receive second data based on the second BT address from a second external device using the BT communication; identify information for connection with the second external device based on the second data using the BT communication; and provide a user interface for connection with the second external device through the display based on the identified information.
