Embodiments of the present invention disclose is a direct mode operation communication method and terminal which are used for flexibly switching to a suitable DMO mode according to different communication environments, reasonably using spectrum resources, and extending multimedia services. The method in the embodiments of the present invention comprises: establishing, by a first terminal, a connection with a second terminal via a first DMO mode, the first DMO mode being a narrowband DMO mode, a wideband DMO mode, or a wideband-narrowband fused DMO dual-mode; receiving, by the first terminal, a wideband DMO signal sent by the second terminal; determining, by the first terminal, whether the quality of the wideband DMO signal satisfies a preset switching condition; and if the quality of the wideband DMO signal satisfies the preset switching condition, switching, by the first terminal, the first DMO mode to a second DMO mode to communicate with the second terminal. The embodiments of the present invention also provide a terminal, which is used for flexibly switching to a suitable DMO mode according to different communication environments, reasonably using spectrum resources, and extending multimedia services.

Direct mode operation communication method and terminal

The embodiments of the present invention disclose a method for processing channel collisions in direct mode operation and a terminal, which can ensure correct transmission of service data and improve user experience. The method in the embodiments of the present invention includes: receiving, by a first terminal, first SCI sent by a second terminal and second SCI sent by a third terminal, and detecting whether a channel collision occurs between the second terminal and the third terminal according to the first SCI and the second SCI; and if a channel collision occurs between the second terminal and the third terminal, generating, by the first terminal, a channel collision message and sending the channel collision message, so that the second terminal and the third terminal can resend the service data according to the channel collision message. The embodiment of the invention also discloses a terminal. The embodiments of the present invention can ensure the correct transmission of the service data and improve user experience.

Method for processing channel collisions in direct mode operation mode, and terminal

A method and apparatus for adjusting timeslot fragments of multiple links in an Automatically Switched Optical Network (ASON). The method includes the steps of: obtaining link information of multiple links necessary for timeslot fragment adjustment, calculating adjusted link information of each link according to the link information, and adjusting a timeslot allocation of each link according to the adjusted link information.

Method and apparatus for adjusting timeslot fragments of multiple links

The present invention relates to a method and an apparatus for consistency verification of traffic engineering link timeslot status, including: the transmitting end transmits a timeslot status verification request message containing the timeslot status object class of a local end of a corresponding traffic engineering link to the receiving end; the receiving end compares and verifies the timeslot status object class of the transmitting end of the corresponding traffic engineering link with the timeslot status object class of the local end after the receiving end receives the message, and notifies a local end link resource manager of the result of verification and the timeslot status object class of the opposite end. With the method according to the embodiments of the present invention, the consistency of traffic engineering link timeslot statuses can be periodically detected, the inconsistency of traffic engineering link timeslot statuses can be discovered as early as possible.
