Method, device and system for device to device (D2D) resource acquisition
First Claim
1. A method for obtaining a Device to Device (D2D) communication resource, the method comprising:
- receiving, by a User Equipment (UE), a system broadcast message; and
obtaining and storing, by the UE, D2D communication resource configuration information carried in the system broadcast message, the D2D communication resource configuration information comprising channel configuration information and a list of identifiers of Public Land Mobile Networks (PLMNs) sharing the D2D communication resource configuration information, so that the UE communicates with another UE based on the stored D2D communication resource configuration information,wherein in a case that the D2D communication resource configuration information is D2D communication public resource configuration information, obtaining by the UE the D2D communication resource configuration information carried in the system broadcast message comprises;
obtaining, by the UE, D2D communication public resource configuration information, carried in the system broadcast message, comprising D2D communication public channel configuration information and the list of identifiers of PLMNs sharing the D2D communication public resource configuration information, by reading the system broadcast message when the UE initially accesses a network which is one of the PLMNs;
wherein a pre-condition for storing by the UE the D2D communication public resource configuration information carried in the system broadcast message is that;
after the D2D communication public resource configuration information, carried in the system broadcast message received by the UE during initially accessing the network which is one of the PLMNs, is obtained, it is determined that an identifier of a PLMN with which the UE is currently registered belongs to the list of identifiers of PLMNs in the D2D communication public resource configuration information.

Abstract
Disclosed are a method, system and device for data transmission in the access point handover process, which is used to solve the problem existing in the prior art that interrupt delay of data plane will be increased when the access point handover is carried out in the case of heterogeneous network. The method of the embodiment of the present invention comprises: a user equipment determines that in the case that Radio Resource Control (RRC) connection remains the same, all or part of the Data Radio Bearers (DRBs) reconfigured from one cell to another cell is needed; the user equipment, in the access point handover process, transmits data through the original DRB, and the original DRB is the last used DRB before the data plane access point handover. The user equipment, during the access point handover process, transmits data through the original DRB, thereby reducing the interrupt delay of the data plane when the access point handover is carried out in the case of heterogeneous network, and further improving the handover efficiency and shortening the data transmission time.
