Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive mobility state information associated with an integrated access backhaul (IAB) node. The mobility state information may include information associated with at least one of: a level of mobility of the IAB node, or a change in mobility of the IAB node. The wireless communication device may perform an operation based at least in part on the mobility state information associated with the IAB node. In some aspects, a wireless communication device may determine that mobility state information associated with an IAB node is to be transmitted, and may transmit the mobility state information associated with the IAB node based at least in part on the determination. Numerous other aspects are provided.

Embodiments of the present disclosure provide a data processing method and a device. The method includes: determining, by a controller, a data packet filtering rule and a data forwarding path; sending, by the controller, the data packet filtering rule and configuration information carrying the data forwarding path to a first node, where the filtering rule is used to match configuration information corresponding to a data packet of the first node, the configuration information includes routing information corresponding to each node in the data forwarding path, routing information includes a queue identifier which is used to identify a transmission queue to which the data packet belongs; forwarding, by the first node and a remaining node, the data packet.

A method and apparatus for providing a virtual network function in a visited network are disclosed. For example, the method receives an attach request or a handover for a user endpoint device, determines a home network for the user endpoint device, receives a profile of the user endpoint device, determines a policy for providing a service to the user endpoint device in accordance with the profile, determines a set of virtual network functions needed for providing the service to the user endpoint device in accordance with the policy, grants the attach request or the handover, designates for each virtual network function of the set of virtual network functions that is needed for providing the service, a corresponding virtual network function for serving the user endpoint device at a location of the user endpoint device, and provides the service to the user endpoint device via the set of virtual network functions.

A method for accessing a wireless access point is provided. The method includes: receiving access information of the wireless access point broadcasted by a preset device, the access information including a Basic Service Set Identifier (BSSID) and an access password of the wireless access point, and the preset device having successfully accessed the wireless access point; unicasting device discovery information according to the BSSID, the device discovery information including the BSSID; receiving feedback information sent by the wireless access point, the feedback information including a Service Set Identifier (SSID) of the wireless access point; and accessing the wireless access point according to the SSID in the feedback information and the access password.

A method and a system are provided for providing a subscription profile on a mobile terminal for communication via a mobile communication network. The method comprises the following steps: the logging in of a first mobile terminal with a first subscription profile to a mobile communication network; the downloading of a second subscription profile to the first mobile terminal via the mobile communication network; and the forwarding of the second subscription profile from the first mobile terminal to a second mobile terminal via a communication channel.

A system is provided for content delivery across heterogeneous networks. The system may store a database of unified identity codes (UICs) for respective categories of information, and in-network addresses of in-network subscriber nodes subscribed to the respective categories of information. At least one in-network subscriber node may be a gateway node of and between a heterogeneous network and another heterogeneous network that includes an out-of-network subscriber node. The system may receive a query including a UIC for a category of information to which one or more in-network subscriber nodes are subscribed, and in response thereto retrieve from the database using the UIC, one or more in-network addresses for the one or more in-network subscriber nodes. The system may also reply to the query with the one or more in-network addresses for use by the source node to transmit content to the one or more in-network subscriber nodes.

Systems and methods for locating a cellular phone are provided. More particularly, systems and methods for providing the location of a requested user's cellular phone from a requesting user's device (e.g., a second cellular phone) based on access rights defined by the requested user. Location descriptions may be provided at a multitude of levels. For example, if a cellular phone, or an identity associated to (e.g., logged into) a cellular phone, has been given access rights to a cell phone's exact location for an indefinite amount of time, that cell phone can receive, on command, the exact location of the approved cell phone. Other levels of location information that can be granted include, for example, proximities, states, and countries.
