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.

Disclosed is a method performed by a first core network node, for enhancing service continuity between a wireless device and a second network via a first network, wherein the first core network node is part of the first network. The method comprises receiving, from the wireless device and/or from a second core network node of the first network, control signalling indicating that the wireless device requires that a tunnel between the wireless device and the second network and via a gateway of the first network is maintained. The method comprises controlling a radio access network node and/or the gateway based on the control signalling and a capability of the first core network node of the first network to maintain the tunnel.

Embodiments of this application provide a multicast/broadcast service communication method and an apparatus, and relate to the communication field, to reduce network resource overheads. The method is as follows: A terminal device determines a first multicast/broadcast service, where the first multicast/broadcast service is a multicast/broadcast service that the terminal device is to leave. The terminal device sends a first message, where the first message carries identification information of the first multicast/broadcast service. Embodiments of this application are applied to a mobile communication system such as 5G.

In some embodiments, a non-transitory computer readable medium is disclosed. In some embodiments, the medium includes instructions for providing a mobile user monitoring solution that, when executed by a processor, cause the processor to capture a first message transmitted over an N11 interface, extract at least one type of session ID and a first Next Generation Application Protocol (NGAP) tunnel endpoint identifier (TEID) from the first message, store the at least one type of session ID and the first NGAP TEID in a first N11 protocol data unit (PDU) session record, capture a second message transmitted over an N3 interface, extract a general packet radio service (GPRS) tunneling protocol (GTP)-user plane (U) TEID from the second message, wherein the GTP-U TEID matches the first NGAP TIED, and retrieve information associated with session details record using the GTP-U TEID.
