The maximum distal UE quantity of business, if having self scheduling resource capability, if so, current residual electricity can support the maximum of dispatch service
Distal end UE quantity and it is expected that the maximum service time) assessment be suitble to use which kind of resources employment methods, assessment result is reported into eNB.
ENB is after the reported result for receiving relaying UE, according to the resource service condition of current service cell, judgement relaying UE
Be not suitable for the excessive distal end UE of access, need to tighten control to the communication resource, then the communication resource will directly be dispatched by eNB, access
Control function also will directly be executed by eNB.Then, eNB feedbacks determine to give relaying UE；Meanwhile eNB is in real time according to service flow
Amount, BSR (Buffer State Report, Buffer Status Report), rate requirement etc. control the access of distal end UE.
In the technical solution of mode one, since the communication resource service condition in current base station covering is nervous, to alleviate
Or communication resource shortages are prevented, it can not allow excessive distal end UE access, eNB that will directly dispatch the UE-TO-NW communication resources, and
Directly manage the access of distal end UE.
Mode two, as shown in Figure 9：
UE is relayed after the connection request for receiving distal end UE, (remaining capacity, power consumption can take according to oneself state and ability
The maximum distal UE quantity of business, if having self scheduling resource capability, if so, current residual electricity can support the maximum of dispatch service
Distal end UE quantity and it is expected that the maximum service time) assessment be suitble to use which kind of resources employment methods, assessment result is reported into eNB.
ENB is after the reported result for receiving relaying UE, according to the resource service condition of current service cell, judgement relaying UE
Be not suitable for the excessive distal end UE of access, need to tighten control to the communication resource, then the communication resource will directly be dispatched by eNB, but accurate
Entering control function will directly be executed by relaying UE；Then, eNB feedbacks determine to give relaying UE.
Meanwhile eNB is in real time according to the other parameters such as resource service condition (rate requirement, portfolio require etc.), with one
Fixed cycle sends the newest signaling comprising access reference standard and gives relaying UE；So that relaying UE controls distal end according to reference standard
The access of UE.
In the technical solution of mode two, since the communication resource service condition in current base station covering is more nervous, eNB
The scheduling UE-TO-NW communication resources, but the operation processing load in order to reduce itself are directly controlled, and accelerates connection as much as possible
It establishes, relaying UE processing is transferred in the admission control of distal end UE.
Mode three, as shown in Figure 10：
UE is relayed after the connection request for receiving distal end UE, according to oneself state and ability (remaining capacity, power consumption, storage
Ability, the maximum distal UE quantity that can be serviced, if having self scheduling resource capability, if so, current residual electricity can be supported to dispatch
The maximum distal UE quantity of service and it is expected that the maximum service time) assessment be suitble to use which kind of resources employment methods, will assessment knot
Fruit reports eNB.
ENB is after the reported result for receiving relaying UE, and according to the resource service condition of current service cell, the communication resource fills
Foot, judgement relaying UE can access current distal end UE, allow to relay UE self scheduling resources, admission control function is also transferred to relay
UE is directly executed；ENB feedbacks determine to give relaying UE, include the condition that eNB withdraws admission control function in feedback result.It withdraws accurate
Enter the condition of control function including but not limited to：Resource usage degree (effective time limit that the resource of relaying UE scheduling can be transferred to),
Allow the quantity of the maximum distal UE of service.
UE is relayed in real time according to flow of services, the BSR of distal end UE is reported, CSI (Channel State
Information, channel state information) and oneself state (remaining capacity, power consumption, storage capacity etc.) and distal end UE request
Priority, rate requirement of communication etc. control the access of distal end UE.
UE is relayed in subsequent communication process, resource service condition is monitored in real time, includes when reaching in feedback result
When withdrawing admission control function condition, relaying UE stops the distal end UE of response subsequent request access, reports eNB and is withdrawn by eNB
Admission control function；ENB executes admission control to the distal end UE that subsequent request accesses；It, can be with when the communication resource is sufficient once again
Admission control function is transferred again gives relaying UE.
In the technical solution of mode three, since the communication resource in current base station covering is sufficient, and UE itself meters are relayed
Calculation ability is strong, in order to faster respond UE-TO-NW communication requirements for greater flexibility, allows sufficient amount of distal end UE access, relaying
UE will directly dispatch the UE-TO-NW communication resources, and directly manage the access of distal end UE.In addition, when the relaying communication resource uses feelings
When condition has exceeded standard as defined in eNB, relaying UE can report eNB that eNB is transferred to withdraw admission control power.This approach increases
Rate is established in the flexibility and connection of UE-TO-NW communications, reduces the operation processing load at the ends eNB, and eNB can in time add
Strong resource management.
