A data transmission method and a first electronic device are provided. The data transmission method includes: sending a first request to a second electronic device in a case that a first electronic device accesses a network hotspot of the second electronic device; receiving a first response of the network hotspot that is fed back by the second electronic device in response to the first request. The first response includes the hotspot information. The data transmission method further includes when the hotspot information does not include a Domain Name Service (DNS) parameter of the network hotspot, configuring a data network route to transmit first data, and configuring a target policy route to transmit second data. The second data is data transmitted between the first electronic device and the network hotspot.

A wireless device sends, to an access and mobility management function (AMF), a request for a multimedia priority service (MPS). The wireless device receives, from the AMF, a connection capability indication indicating network support for a connection of the wireless device for the MPS. The wireless device sends to the AMF, based on the connection capability indication, a request for a packet data unit (PDU) session establishment.

A data transmission method and an apparatus are provided, to resolve a problem that network communication between a communications apparatus and an external network device cannot be ensured. A network protocol stack is deployed on both a wireless communications unit and a service processing unit, and the wireless communications unit is responsible for distribution. This can ensure processing of a network service and a throughput of a wireless network when a processing capability of the wireless communications unit is weak. The network protocol stack is deployed on the wireless communications unit. When the service processing unit is powered off, the wireless communications unit can still communicate with an external device, for example, remote wakeup.

A method for selecting a content forwarding node in a vehicle ad-hoc network on the basis of service type, comprising the following steps: calculating a bandwidth occupation proportion factor according to the type of requested content information and a bandwidth occupation situation of a neighboring vehicle which can perform forwarding in a one-hop transmission range; defining a virtual arrival time of a candidate forwarding vehicle to an initial request vehicle according to the distance between the neighboring vehicle and the initial request vehicle and a driving speed of the neighboring vehicle; calculating a forwarding node impact factor according to the bandwidth occupation proportion factor and the virtual arrival time; and selecting a forwarding node according to the forwarding node impact factor.

Provided is a data transmission method, including: receiving, by a target base station, a RRC resume request message and first data that are transmitted by a terminal device; transmitting, by the target base station, a retrieve terminal context request message to an anchor base station, the retrieve terminal context request message carrying the first data or first indication information indicating transmission of the first data; and receiving, by the target base station, a reply message transmitted by the anchor base station, the reply message carrying second indication information indicating whether the anchor base station is capable of transmitting the first data to a core network. The first data is transmitted to the core network by the target base station in response to the second indication information indicating that the anchor base station is incapable of transmitting the first data to the core network.

The first data is transmitted to the core network by the target base station in response to the second indication information indicating that the anchor base station is incapable of transmitting the first data to the core network.

Disclosed herein is a method performed by a network node and a network node performing the method, which implements a DNS function in a mobile network, the method comprising the actions: receiving; a DNS query that originated at a UE; in response to receiving; the DNS query, determining; to trigger dynamic activation of Local Break Out, LBO, for a session of the UE at a breakout site of the mobile network for traffic between the UE and an edge AS site that is connected to the breakout site; and upon determining; to trigger dynamic activation of LBO for the session of the UE at the breakout site of the mobile network for traffic between the UE and the edge AS site, triggering; dynamic activation of LBO for the session of the UE at the breakout site of the mobile network for traffic between the UE and the edge AS site.

Techniques described herein provide pooling of radio access network (RAN) resources in a disaggregated RAN in a manner that enables dynamic re-homing of RAN functions with minimal disruption to stateful communications. The RAN is a hierarchical arrangement of RAN units, each having an associated state at any given time. A RAN state pooling system (RSPS) is in communication with a pool of the RAN units via a high-speed communication channel. The RSPS is configured to maintain an updated repository of the state information for the RAN units in its serviced pool. In the event of re-homing from a first RAN unit to a second RAN unit in the pool (e.g., due to the first RAN unit failing, becoming overloaded, etc.), the RSPS provides the second RAN unit with the updated state information for the first RAN unit to facilitate a stateful re-homing.
