A communication device for use in a system including a database storing a unique identifier and position information for every mobile communication terminal is provided with an acquisition unit that acquires, based on the unique identifier of a mobile communication terminal serving as a communication destination, the position information of the mobile communication terminal serving as the communication destination from the database, and acquires an IP address of a router accommodating the mobile communication terminal serving as the communication destination, based on the acquired position information, and a communication unit that transmits a packet having the IP address in a header.

The present disclosure discloses an information processing method and apparatus, a storage medium, and a processor. The method includes: a terminal determines information or service that needs to be transmitted; and the terminal requests system information from a network device when the terminal is determining transmission of the information or the service. The present disclosure solves the technical problem of the uncertainty of the system information request process.

Embodiments of the present disclosure provide a method, an apparatus and a system for data connection management. The method for data connection management includes: obtaining, by a user equipment UE, first instruction information, wherein the first instruction information is used for instructing to close or open a data connection; and transmitting, by the UE, the first instruction information to a packet data network gateway P-GW, for enabling the P-GW to stop or start data transmission of at least one bearer of the UE according to the first instruction information.

The present disclosure provides a method for establishing a session, which is applied to a terminal device and includes sending a session establishment request to a network device. The session establishment request is used to request to establish a first session. The session establishment request includes first indication information. The first indication information indicates that the first session is a deactivated session or an activated session. The method also includes receiving a response message of the session establishment request from the network device. If the number of DRBs has reached a number threshold, the terminal device can request the network device to establish a deactivated first session via the first indication information. When the number of DRBs is less than the number threshold, the terminal device or the network device can activate the first session.

Systems described herein provide techniques for establishing and modifying user plane communications sessions between Long-Term Evolution (“LTE”) User Equipment (“UE”) devices, connected to LTE base stations, and a Fifth Generation (“5G”) core network. An LTE-5G Interworking function (“LTE-5G IWF”) may logically generate a virtual 5G UE and/or 5G base station, map a LTE UE to the virtual 5G UE, and cause the establishment of a Protocol Data Unit (“PDU”) Session, at the 5G core network, with the virtual 5G UE. The LTE-5G IWF may provide PDU Session information to the LTE UE and base station to facilitate the establishment of user plane communications (e.g., via a tunnel) between the LTE UE and the 5G core network. The LTE-5G IWF may also receive modification parameters, such as Quality of Service (“QoS”) parameters, and provide instructions to the 5G core and/or to the LTE UE to handle traffic according to such parameters.

Embodiments of this disclosure provide methods, apparatuses, non-transitory computer-readable storage medium, and electronic devices for a multicast broadcast service. A method includes: receiving a first multicast broadcast service (MBS) session start request, selecting an intermediate user plane node, transmitting a first user plane MBS session establishment request to the intermediate user plane node, receiving a first user plane MBS session establishment response fed back by the intermediate user plane node and transmitting a second MBS session start request to a son control plane node to instruct the son control plane node to allocate son user plane nodes to the intermediate user plane node.
