Problems solved by technology

[0010] It can be seen from the above that in the future development of the mobile communication system, in order to better meet the needs of users and improve the efficiency of interactive information, the D2D Discovery mechanism, or even the D2D Communication mechanism will inevitably be introduced. However, in the current existing technology, The relevant behaviors of D2D monitoring UEs (including D2D discovery monitoring UEs and D2D communication monitoring UEs) have not been discussed yet. If D2D monitoring UEs are in all possible resources, then the UEs in the mobile communication system will consume more power. Therefore, the industry It is urgent to propose a D2D monitoring UE solution that can save power, so as to realize the introduction of the above-mentioned related mechanisms.

Embodiment 1

[0108]Embodiment 1: eNB broadcasts dedicated D2D discovery resources and corresponding identifiers

[0109] In the D2D discovery dedicated resource allocation mode, the D2D discovery monitoring resource pool is P1, where the set P11 in P1 is used for application 1 (that is, APP ID1), P12 is used for application 2 (APP ID2), and P13 is used for application 3 (APP ID3). . UE1 is interested in APP ID1 and expects to find nearby users who are using the application software; UE2 is interested in APP ID4 and expects to find out whether the friends of APP ID4 are nearby. Specific steps are as follows:

[0110] Step 1: The eNB broadcasts the D2D discovery monitoring resource pool and the corresponding identifier in the D2D discovery dedicated resource allocation mode. The possible organization methods may be:

[0111] 1) Resource pool P1, and its identification list {APP ID1, APP ID2, APP ID3};

[0112] 2) Further subdivide the resource pool and its corresponding identification, th...

Embodiment 2

[0117] Embodiment 2: The eNB notifies the UE in a dedicated way

[0118] UE1 is interested in Group (group) ID1; UE2 is interested in Group ID4. In the D2D Communication dedicated resource allocation mode, the D2D Communication monitoring resource pool is P1, where the set P11 in P1 is used for group1 (Group ID1) communication, P12 is used for group2 (Group ID2), and P13 is used for group3 (Group ID3). Specific steps are as follows:

[0119] Step 1: UE1 sends a monitoring resource request to eNB, which carries the group ID1 it is interested in, and if there are multiple interested IDs, it can carry the ID list;

[0120] Step 2: The eNB searches for the resource set corresponding to Group ID1 according to the allocated D2D Communication dedicated resource set, and the search result is set P11, then the eNB notifies UE1 that the D2D Communication dedicated monitoring resource set is P11 through a dedicated message, which may carry the valid time of the message ;

[0121] Step...

Embodiment 3

[0125] Embodiment 3: eNB / CE allocates dedicated resources through reservation

[0126] The eNB reserves a part of the resource set for the corresponding application layer or group for D2D discovery dedicated resource allocation. For example, the eNB reserves a part for APP ID1 and APP ID2 through the OAM (Operation Administration and Maintenance) configuration method D2D discovery resource pool Pool1 is used for D2D discovery dedicated resource allocation under APP ID1 and APP ID2 applications.

[0127] In order to support inter-cell D2D discovery, eNBs can also exchange reserved D2D discovery resource pools and corresponding application layer identification lists, so that eNBs can obtain D2D discovery resource allocation information of neighboring cells.

[0128] Similarly, this method is also applicable to D2D communication.

Abstract

The invention discloses a resource monitoring method, user equipment and network equipment. The resource monitoring method can include that the user equipment UE receives auxiliary information sent from the network equipment; the UE monitors resources according to the auxiliary information. The resource monitoring method can include that the network equipment generates auxiliary information; the network equipment sends the auxiliary information to the UE to make the UE monitor resources according to the auxiliary information. The resource monitoring method confirms the resource information corresponding to an expected resource identification of the UE through pre-allocated corresponding relationship between the resource identification and resource information according to the demand of the UE and realizes resource monitoring according to the resource information, and therefore, the UE realizes to monitor the special resource in the monitoring process, the trouble due to monitoring all the resources in the monitoring process is avoided, and accordingly the power consumption of the UE is lowered, and the energy saving (electricity saving) is realized.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a resource monitoring method, user equipment and network equipment. Background technique [0002] 1. The existing mobile communication system [0003] In the LTE (Long Term Evolution, Long Term Evolution) system, the transmission and reception of data is realized by centralized control of the network, that is, the uplink and downlink data of the user equipment UE are all sent and received under the control of the network. UE-to-UE communication is forwarded and controlled by the network. There is no direct communication link between UEs, and UEs are also allowed to send uplink data by themselves. [0004] 2. D2D (Device to Device, end-to-end) proximity service [0005] In 3Gpp, D2D proximity services include the following two categories: [0006] D2D Discovery (end-to-end discovery): UE uses E-UTRA to confirm that another UE is nearby. For example, D2D UE can use ...
