Embodiment 1

[0249] Embodiment one: if Figure 5 As shown in the data flow sharing scenario, the base station determines which adjacent terminal is the relay terminal and directly allocates resources:

[0250] 1. The request UE (requesting terminal, such as the first node above) sends a "resource sharing request" through the sidelink (direct link) interface. The request message at least carries the terminal ID, the size of the data to be sent, the QoS requirement of the data to be sent, and the A hash of the content of the request message encrypted with its private key.

[0251] 2. The adjacent UE that receives the "Resource Sharing Request" message inquires from the base station whether the requesting terminal UE is credible, carrying the UE ID of the requesting terminal, the size of the data to be sent, and the QoS requirements of the data to be sent.

[0252] 3. The base station verifies whether the requesting terminal is authentic, obtains the public key of the requesting terminal fro...

Embodiment 2

[0262] Embodiment two: if Figure 6 As shown, the requesting terminal requests power resource sharing, and the neighboring UEs come from multiple cells:

[0263] 1. The requesting terminal broadcasts a power sharing request through the inter-UE interface, and the request carries the UE ID of the requesting terminal and the UE ID encrypted by its private key.

[0264] 2. Neighboring UEs that receive the power sharing request message and wish to share power for the requesting terminal request the public key information of the requesting terminal from their respective base stations.

[0265] 3-4. These base stations obtain the public key of the requesting terminal from the public key server and return it to the neighboring UE.

[0266] 5. The adjacent UE responds to the requesting terminal through the inter-UE interface, requesting to share power for it.

[0267] 6. The requesting terminal determines which / neighboring UEs are power sharing UEs and which / neighboring UEs are veri...

Embodiment 3

[0272] Embodiment 3: Location Information Sharing

[0273] 1. The UE that needs to be positioned sends an assisted positioning request to the surrounding UEs. The request message is used to request their location information from the surrounding UEs, and / or request to use their location information, and / or request assistance in performing positioning measurements, and / or request Use their positioning measurements.

[0274] The surrounding UEs are UEs that want to participate in this assisted positioning, and may also need to meet certain conditions, for example, the channel quality with the UE to be positioned is higher than a certain threshold.

[0275] The assisted positioning request carries one or more of the following information: the ID of the UE to be positioned; the required location information type indication: one or more of the latest position estimate, historical position estimate, latest measurement result, and historical measurement result; Time stamp needs to b...

Abstract

The embodiment of the invention provides a method and a device for sharing resources among nodes and the nodes. The method at a first node side comprises the following steps: the first node sends resource sharing request information to a second node; the first node receives a resource sharing response message sent by the second node, wherein the resource sharing response message is sent after the second node determines that the first node is a trusted node; and the first node shares the resources of the second node. According to the scheme of the invention, the problem of mutual trust of resource sharing is solved, so that more adjacent terminals are willing to share resources to the requesting terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and node for resource sharing among nodes. Background technique [0002] When traveling domestically, mobile phone traffic is relatively sufficient, and most restaurants and hotels have free WIFI. In foreign countries, especially in Latin America and Africa, some countries with less developed communications may not have the benefits of free Internet access. In this case, if you do not have an overseas SIM card or have not purchased an overseas data package, you cannot use data traffic. This can greatly degrade the user experience. [0003] For the situation where the UE has no network coverage but wants to communicate with the network, the UE-to-Network Relay technology introduced by the Rel-13 Prose protocol can be used, which forwards the data of the wireless terminal to the network through the adjacent relay terminal. [0004] At least the fo...
