Abstract: A login method includes: after a login process of a service apparatus is triggered, acquiring verification information of a target primary account, and sending the verification information to an identity management apparatus; after receiving the verification information by the identity management apparatus, performing identity verification on the target primary account by using an identification information set of a registered primary account, and after the identity verification is passed, acquiring login information of at least one sub-account associated for the service apparatus in advance with the target primary account and sending the login information to the service apparatus; and determining, by the service apparatus, a target sub-account based on the login information and logging in to a server side.

Abstract: An initiation request is received for initiating a service, where the initiation request is generated by a user of a first communication group participating in a communication session. A participation response is received from a plurality of users of the first communication group that defines a second communication group participating in the communication session. A participation result is determined that includes service conditions associated with the user of the first communication group and the plurality of users of the second communication group. In response to determining the participation result, a third communication group is generated that includes target users for completing the service.

Abstract: The invention discloses a flexible offshore pipeline for oil and gas transportation stabilized on seabed by anchorage piers. It comprises cable (1) and flexible pipe (2) for oil and gas transportation, anchorage pier assemblies (3) to prevent the cable from drifting, and constraining assemblies (4) to restrict the flexible pipe (2) are sequentially provided on the cable. The anchorage pier assembly (3) comprises a gravity block (31) and the first clamping tool (32), and the first clamping tool (32) connects with the cable (1). The invention uses the flexible pipe (2) to build up offshore pipeline for oil and gas transportation, and anchorage pier assembly (3) and constraining assembly (4) for constraining the flexible pipe (2) are sequentially provided on the cable (1), which can restrict the flexible pipe, achieve reliable oil and gas transportation and prevent the flexible pipe drifting on the seabed. The pipeline system can protect the flexible pipe, are strong and reliable and the cost of pipeline is low.
