Disclosed herein is a system comprising a first backhaul node, a second backhaul node, and multiple sites that each comprise a respective node configured to maintain a first communication link with the first backhaul node and a second communication link with the second backhaul node, operate in a first mode in which the respective node engages in communication with the first backhaul node over the first communication link and does not engage in communication with the second backhaul node over the second communication link, detect a triggering event associated with the first communication link, and in response to detecting the triggering event, dynamically switch from operating in the first mode to operating in a second mode in which the respective node engages in communication with the second backhaul node over the second communication link and does not engage in communication with the first backhaul node over the first communication link.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to the disclosure, it is possible to efficiently support data forwarding during conditional handover and dual stack protocol handover.

Aspects of the present disclosure provide techniques switching a communication link for wireless systems with multiple parents, such as an Integrated Access and Backhaul (IAB) network or other type of network. In some cases, a node determines a partition of a number of desired guard symbols between a first parent node and a second parent node; sends, to the first parent node and to the second parent node, at least one indication of a partitioned number of the desired guard symbols for switching between the first parent node and the second parent node; receives at least one indication of a number of provided guard symbols from the first and second parent nodes; and switches a communication link from the first parent node to the second parent node in accordance with the at least one indication of provided guard symbols by the first parent node and the second parent node.

A method for utilizing quality of service information in a network with tunneled backhaul is disclosed, comprising: establishing a backhaul bearer at a base station with a first core network, the backhaul bearer established by a backhaul user equipment (UE) at the base station, the backhaul bearer having a single priority parameter, the backhaul bearer terminating at a first packet data network gateway in the first core network; establishing an encrypted internet protocol (IP) tunnel between the base station and a coordinating gateway in communication with the first core network and a second core network; facilitating, for at least one UE attached at the base station, establishment of a plurality of UE data bearers encapsulated in the secure IP tunnel, each with their own QCI; and transmitting prioritized data of the plurality of UE data bearers via the backhaul bearer and the coordinating gateway to the second core network.

Provided are a method and system for realizing a service-based mobile originated short message service. The method for realizing a service-based mobile originated short message service (MO SMS) includes: after receiving a short message transferred from a user equipment, an SMSF entity querying, from a NRF entity, information of a network function that can provide a MO SMS forwarding service; when it is determined, according to a query result, that a corresponding SMS-IWMSC can provide the MO SMS forwarding service, the SMSF entity sending the short message to the SMS-IWMSC; and the SMS-IWMSC sending the short message to a SC, so that the SC sends the short message to a corresponding receiver of the short message.

Embodiments of the present disclosure disclose a function scheduling method, a device, and a system. The method includes: sending, by a control plane network element, a first request to a user plane network element, where the first request is used to request the user plane network element to perform a first function, and the first function is a function supported by both the control plane network element and the user plane network element; and disabling, by the control plane network element, the first function. In the solutions of the embodiments of the present disclosure, a function supported by both the user plane network element and the control plane network element can be flexibly processed.
