Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration for a set of bandwidth part groups including an intra-group switching delay and an inter-group switching delay, where the intra-group switching delay is smaller than the inter-group switching delay. The UE may communicate with a base station on a first bandwidth part of a first bandwidth part group of the set of bandwidth part groups. The UE may switch to a second bandwidth part of the first bandwidth part group based at least in part on the intra-group switching delay, or the UE may switch to a third bandwidth part of a second bandwidth part group based at least in part on the inter-group switching delay. The UE may communicate with the base station on the second bandwidth part or the third bandwidth part based on switching.

This application discloses a communication method. When determining that a network used to provide a service does not meet a transmission requirement of service data, a terminal device requests, from a PCF, an SMF, or an NWADF, to analyze a reason why the network does not meet the transmission requirement of the service data. The PCF, the SMF, or the NWADF obtains information used to recover a service, and sends the information to a device that performs a service recovery operation, for example, the terminal device or an access network device. The information used to recover the service is used to enable the network to meet the transmission requirement of the service data.

The present disclosure may provide a method of operating a terminal based on a plurality of networks in a wireless communication system. Herein, the method of operating the terminal may include establishing a connection with a public land mobile network (PLMN), determining whether or not to simultaneously access the PLMN and non-public networks (NPN), transmitting, to the NPN, indication information indicating a simultaneous access request for the PLMN and the NPN, receiving, from the NPN, supported PLMN list information, and when the connected PLMN is included in the supported PLMN list information, accessing the NPN through a packet data unit (PDU) session of the PLMN. Herein, a supported PLMN list may be a list which is determined according to whether or not a quality of service (QoS) is supported based on a service level agreement (SLA) between the PLMN and the NPN.

A method includes a first access network device that sends first indication information to a second access network device. The first indication information indicates information about a current active BWP and/or transmission rate information of a terminal device on the first access network device. The second access network device determines information about a first-time active BWP and/or BWP configuration information of the terminal device on the second access network device based on the first indication information. The method may be used to enable the second access network device to determine the appropriate information about the first-time active BWP and/or the appropriate BWP configuration information of the terminal device on the second access network device. In this way, service interruption caused by switching of an active BWP is reduced, and/or service interruption caused by changing of a BWP configuration is reduced.

A first network function (NF) instance sends a request for a session to a second NF instance. The first NF instance receives a response, from the second NF instance, that includes a binding header that includes a failover mode identifier, a designated number of retry attempts, and a retry mode. The first NF instance sends a second request for the session to the second NF instance. The first NF instance determines if an error or a timed out response has occurred subsequent to sending the second request to the second NF instance, and re-sends, in response to the error or timed out response, the second request based on the failover mode identifier, the designated number of retry attempts and the retry mode from the binding header.

There is disclosed a method of processing a transaction request. The transaction request is associated with a computer transaction which has to be executed in a succeed-or-fail-as-a-whole manner. The method is executable in a distributed processing system having a plurality of nodes. Each of executing nodes is associated with a pre-defined type of the computer transaction and is directly addressable by a controlling node. In response to receiving by the controlling node, from a client device, a transaction request, the controlling node determines, based on the pre-defined type of the computer transaction, a specific node of a set of executing nodes responsible for the pre-defined type of the computer transaction and sends the transaction request directly to the determined specific node for execution thereof. While the determined specific node executed the transaction requests, it blocks receiving of additional transaction requests until the transaction request is executed.
