After the terminal with wireless small station ability to work enters small station mode of operation, the mode that in prior art, access node specifies can be followed and carry out work, such as, by sending the common signalings such as broadcast, after the response message receiving the terminal needing data forwarding service, access the terminal that this needs data forwarding service.Also can access not in accordance with the mode of common access node the terminal needing data forwarding service, but access switches the terminal needing data forwarding service of coming by control appliance.
Describe the trigger flow of above two kinds of triggering modes below respectively in detail.
Triggering mode one
Control appliance triggers before the terminal with wireless small station ability to work enters wireless small station mode of operation, such as before step 701, have wireless small station ability to work terminal need to control appliance reporting information, at least comprise in the information reported control appliance can be allowed to determine this terminal has the information of wireless small station ability to work.
Preferably, the information reported also comprises measurement report, and described measurement report comprises one of following information or combination in any: back haul link and the transmission quality information with the terminal of wireless small station ability to work; The terminal with the terminal surrounding of wireless small station ability to work has link and the transmission quality information of the terminal of wireless small station ability to work to this; There is link and the transmission quality information of the terminal self of the terminal surrounding of wireless small station ability to work.
In step 701, the information that the terminal with wireless small station ability to work received sends is carried out comprehensive process and judgement by control appliance, when judging that the terminal that one of them has wireless small station ability to work starts after as wireless small station mode of operation, can bring lifting to overall network efficiency, then the terminal having wireless small station ability to work to this sends the signaling and wireless small station configuration information that start wireless small station mode of operation.
The process of all the other steps, with shown in Fig. 7, does not repeat them here.
Triggering mode two
Under this triggering mode, before step 701, the terminal with wireless small station ability to work determines whether to start wireless small station mode of operation voluntarily.If determine to start wireless small station mode of operation, then send the request message starting wireless small station mode of operation to control appliance.The request message of the startup wireless small station mode of operation that control appliance sends based on the terminal with wireless small station ability to work,
In step 701, after control appliance receives this request message, carry out comprehensive assessment and judgement, then wireless small station configuration information is sent to the terminal receiving control apparatus with wireless small station ability to work after judging to meet the condition of open wireless small station pattern, and allow this terminal with wireless small station ability to work to start wireless small station mode of operation, the signaling and wireless small station configuration information that start wireless small station mode of operation is sent to this terminal.
Preferably, the terminal with wireless small station ability to work is sending in the request message starting wireless small station mode of operation the quality of service information that can also carry some these terminals with wireless small station ability to work and can provide directly to control appliance, frequency, bandwidth, processing speed and storage capacity etc. that such as this terminal with wireless small station ability to work is supported, more targeted with the wireless small station configuration information making control appliance send the terminal that this has wireless small station ability to work, lifting can be brought to overall network efficiency.
The process of all the other steps, with shown in Fig. 7, does not repeat them here.
In following three kinds of situations, the terminal with wireless small station ability to work can be determined to start wireless small station mode of operation voluntarily:
Situation one: the terminal with wireless small station ability to work sends broadcast probe message, and this broadcast probe message is used to indicate the terminal sending described broadcast probe message and has wireless small station ability to work; This terminal with wireless small station ability to work sends the request message starting wireless small station mode of operation after receiving the response message needing the terminal of data forwarding service to return according to described broadcast probe message to described control appliance.Preferably, broadcast probe message comprises the message transmission rate and quality of service information that the terminal with wireless small station ability to work can provide.
Concrete, the broadcast probe message that the terminal with wireless small station ability to work sends can be similar with D2D broadcast signaling.The terminal that the terminal receiving this broadcast probe message can determine to send this broadcast probe message has wireless small station ability to work, also can obtain message transmission rate and quality of service information that the terminal that sends this broadcast probe message can provide.For the terminal of surrounding, after receiving this broadcast probe message, first judge the link-quality of the terminal self to this with wireless small station ability to work, and self is the need of data forwarding service, if all met the demands, the terminal that then can have wireless small station ability to work to this sends response message, to allow this terminal with wireless small station ability to work determine there is the terminal needing data forwarding service around it.After the terminal with wireless small station ability to work receives response message, confirm there is the terminal needing data forwarding service around, then send the request message starting wireless small station mode of operation to control appliance.
Situation two: the terminal with wireless small station ability to work receives the broadcast probe message needing the terminal of data forwarding service to send, and this broadcast probe message has the terminal of wireless small station ability to work for detecting; After the terminal check with wireless small station ability to work can provide data forwarding service for the terminal sending described broadcast probe message, response message is sent to the terminal sending described broadcast probe message, and after receiving the acknowledge message that the terminal that sends described probe message returns according to described response message, send the request message starting wireless small station mode of operation to control appliance.
Concrete, need data forwarding service terminal send broadcast probe message can with D2D (DevicetoDevice, terminal-to-terminal service) broadcast signaling is similar, and whether detection has the terminal with wireless small station ability to work that can provide data forwarding service around.After the terminal with wireless small station ability to work receives this broadcast probe message, judge whether self there is wireless small station ability to work, and judge whether this terminal meets the demands to link-quality between oneself, after all meeting the demands, the terminal of data forwarding service is needed to send response message to this.This response message needing the terminal of data forwarding service likely to receive a more than terminal with wireless small station ability to work to send, the conditions such as the maximum data forwarding rate that the terminal that now can have wireless small station ability to work according to each can provide or link-quality, therefrom select a terminal with wireless small station ability to work the most satisfactory, and send acknowledge message to the terminal with wireless small station ability to work in selecting.After the terminal with wireless small station ability to work receives the confirmation message, send the request message starting wireless small station mode of operation to control appliance.
Situation three: the terminal with wireless small station ability to work determines the request needing to start wireless small station mode of operation according to the change of self preset state, then send the request message starting wireless small station mode of operation to control appliance.
Such as, the wireless small station mode of operation that the terminal with wireless small station ability to work is preset is closed condition, when the request that needs to start wireless small station mode of operation is determined in the change of the artificial preset state of user, the switch of wireless small station mode of operation that what user was manual open, now this terminal can send directly to control appliance the request message starting wireless small station mode of operation.
There is the terminal of wireless small station ability to work when the wireless small station configuration information sent according to control appliance is configured, except carrying out foregoing protocol stack arrangement, also to carry out carrying and map configuration, thus when carrying out data forwarding service as wireless small station, can bearer management be carried out.
Terminal and host's access node thereof with wireless small station ability to work all need to carry out carrying the configuration mapped, and its process can comprise:
Host's access node of the terminal with wireless small station ability to work and the terminal with wireless small station ability to work, the carrying mapping relations that receiving control apparatus sends, and carry out up and/or descending carrying mapping according to carrying mapping relations; Wherein, in carrying mapping relations, there is in the carrying of the carrying accepting the terminal of data forwarding service and the terminal with wireless small station ability to work the carrying of same or similar transmission property, be mapped to during same Ux mouthpiece carries, there is described in described Ux mouth refers to the interface between the terminal of wireless small station ability to work and host's access node.
Carrying mapping relations comprise the terminal accepting data forwarding service carrying, this have the carrying of the terminal of wireless small station ability to work and Ux mouthpiece carry between mapping relations.The terminal with wireless small station ability to work can determine the data in how transmission bearer according to these carrying mapping relations.Each Ux mouthpiece carries the identical or similar service quality (QualityofService referring to transmission of middle transmission property, be called for short: QoS) attribute is same or similar, such as be and ensure bit rate (GuranteedBitRate, be called for short: GBR)/non-GBR, transmission error rates requires same or similar, propagation delay time requires same or similar, and transmission priority is same or similar.
The terminal with wireless small station ability to work when carrying out uplink, for dedicated tunnel is set up in each each carrying accepting the terminal of data forwarding service; For the carrying of the terminal of current transmission upstream data, corresponding dedicated tunnel is used to encapsulate upstream data.
Such as, as shown in Figure 8, the carrying RB of UE1 (English: RadioBearer) 1 and the carrying RB3 of UE2 there is identical transmission property, be mapped in the carrying RB5 of identical Ux mouth and transmit; The carrying RB2 with carrying RB4 and the UE1 of the terminal of wireless small station ability to work has identical transmission property, is mapped in the carrying RB6 of identical Ux mouth and transmits.
The terminal with wireless small station ability to work, when carrying out downlink transfer, is determined the target carrying of corresponding target terminal, and downlink data is sent to described target terminal according to the dedicated tunnel encapsulation header of downlink data.But because the same Ux mouthpiece that is carried on having multiple different terminals carries middle transmission, therefore there is the terminal of wireless small station ability to work after receiving during Ux mouthpiece carries the data transmitted, need to distinguish the downlink data of different terminals, downlink data is sent to correct target terminal.
The terminal with wireless small station ability to work just carries out transfer transmission to the data of the terminal receiving data forwarding service according to the mode of existing transfer transmission, now has between the terminal of wireless small station ability to work and host's access node and can set up special tunnel for each carrying of the terminal of each reception data forwarding service.It is relation one to one between the special tunnel set up for each carrying and of terminal of each reception data forwarding service carry, the data of the terminal of each reception data forwarding service of the mixing therefore in each carrying of Ux mouth, it is which receives which carrying of the terminal of data forwarding service that the mark all can setting up special tunnel by each carrying identifies this.Such as, have between the terminal of wireless small station ability to work and host's access node and can set up GPRS channel protocol-user face (GPRSTunnelProtocolUserPlane for each carrying of the terminal of each reception data forwarding service, be called for short: GTP-U) tunnel, can identify by the head of GTP-U data which carrying that this is the terminal of which reception data forwarding service.
Starting point or the terminal with the data of the terminal of wireless small station ability to work are itself, therefore no longer need to set up tunnel, only need through the data of inner protocol encapsulation, such as RLCSDU (ServiceDataUnit, service data unit).Can with following two kinds of modes carry out resolving and distinguish Ux mouthpiece carry in the data with the terminal of wireless small station ability to work and receive the data of terminal of data forwarding service.
A kind of mode is: the terminal with wireless small station ability to work carries out blind check according to dedicated tunnel solution packet mode and protocol data bag solution packet mode respectively to the data that described Ux mouth receives, if according to dedicated tunnel solution packet mode blind check success, the target terminal then confirming the data that described Ux mouth receives is the terminal accepting data forwarding service, if according to protocol data bag solution packet mode blind check success, then confirm the target terminal of the data that described Ux mouth receives for described in there is the terminal of wireless small station ability to work.Such as, the data had in each carrying of the terminal of wireless small station ability to work encapsulate through GTP-U, and the data with the terminal of wireless small station ability to work encapsulate through RLCSDU.When blind check is carried out to data, decode according to the solution packet mode of GTP-U data solution packet mode and RLCSDU data respectively, according to which kind of mode successfully decoded, then can determine the encapsulated type of these data, and then determine that these data belong to the data of the terminal with wireless small station ability to work or belong to the data of the terminal with wireless small station ability to work.
Another kind of mode is: the terminal with wireless small station ability to work obtains the indication information carried in the data that described Ux mouth receives, described indication information is used to indicate target terminal to be had the terminal of wireless small station ability to work or accepts the terminal of data forwarding service, and determines the target terminal of the data that described Ux mouth receives according to described indication information.Such as, the indication information carried in data is the specific fields of data packet head, has 2 bits in this specific fields, and wherein this specific fields is 00 data representing that these data are the terminal with wireless small station ability to work; Being 01, to represent these data be the first data accepting the terminal of data forwarding service; Being 11, to represent these data be the second data etc. accepting the terminal of data forwarding service.
Again such as, the indication information carried in data is a newly-increased specific fields, the data packet header of the data after Reseal is positioned at after this newly-increased specific fields and data Reseal, have 1 bit in this newly-increased specific fields, wherein this newly-increased specific fields is 0 data representing that these data are the terminal with wireless small station ability to work; It is 1 data representing that these data are the terminal accepting data forwarding service.
There is the terminal of wireless small station ability to work when the terminal for accepting data forwarding service is served, the problem produced when also needing to solve the fast mobile terminal relating to and there is wireless small station ability to work.
The mobile management relating to the terminal with wireless small station ability to work is divided into two large classes:
The mobile management accepting the terminal of data forwarding service under the terminal one, with wireless small station ability to work;
Two, there is the mobile management of the terminal self of wireless small station ability to work.
Mobile management under different situations is described below respectively.
For the mobile management accepting the terminal of data forwarding service under the terminal with wireless small station ability to work, the terminal with wireless small station ability to work of serving for it can be considered as a normal access node by the terminal accepting data forwarding service, therefore this accepts the mobile management of the terminal of data forwarding service, is the same with the mobile management of access node in prior art to the terminal under it.Concrete, example accept the terminal of data forwarding service be replaced by its service there is the terminal of wireless small station ability to work time the reconfiguration course that carries out; The terminal switch accepting data forwarding service has the process etc. of the terminal of wireless small station ability to work to other.Do not repeat them here there is wireless small station ability to work terminal under the mobile management accepting the terminal of data forwarding service specifically adopt which kind of technological means.
For the mobile management of terminal self with wireless small station ability to work, two kinds of situation discussion can be divided into again.For the first situation, the terminal with wireless small station ability to work moves with the terminal receiving data forwarding service simultaneously, but does not have relative movement between them.The most typical scene of this situation is the car that the terminal with wireless small station ability to work and the terminal receiving data forwarding service are positioned at the high-speed mobile that coexists.Now, when the terminal with wireless small station ability to work only moves across host's access node, and the connection of control appliance is when remaining unchanged, control appliance may need the terminal to having wireless small station ability to work to reshuffle, and corresponding protocol stack needs to reset.For the terminal receiving data forwarding service under the terminal with wireless small station ability to work, when not needing to switch the terminal with wireless small station ability to work, then do not need to reshuffle, do not need the reset of protocol stack yet.When the fast mobile terminal with wireless small station ability to work is outside the control area of control appliance, the terminal then now with wireless small station ability to work needs to switch, the terminal of the reception data forwarding service of its lower service also needs to switch, two switching flows can independently carry out, and also can carry out certain binding and then optimize this process.
For the second situation, the terminal that another kind has wireless small station ability to work is moved, and has between the terminal of wireless small station ability to work and the terminal of its lower reception data forwarding service of serving simultaneously and has relative movement.The most typical scene of this situation is that the terminal receiving data forwarding service keeps static, and the terminal with wireless small station ability to work is moved.The terminal now with wireless small station ability to work needs according to circumstances, carries out reshuffling or handoff procedure, and now its lower terminal receiving data forwarding service needs to find new access node, reshuffles accordingly or handoff procedure.The mobile process with the terminal of wireless small station ability to work and the terminal of reception data forwarding service should process respectively.
When carrying out mobile management, the terminal with wireless small station ability to work receives the reconfiguration message of described control appliance transmission, and reshuffles according to described reconfiguration request message; Wherein, described reconfiguration request message is that described control appliance sends when the terminal described in judging with wireless small station ability to work moves between the different access nodes that described control appliance connects; Or
The switching command that the core net that the terminal with wireless small station ability to work receives described control appliance ownership sends, and be switched to target control equipment according to described switching command; Wherein, described switching command is that described core net sends when the terminal described in judging with wireless small station ability to work moves across chain of command anchor point.
When following situation occurs, need to start wireless small station mode of operation process ends: the terminal with wireless small station ability to work is considered for factors such as economize on electricitys, needs to close wireless small station mode of operation; Control appliance judges no longer to need the terminal with wireless small station ability to work to start wireless small station mode of operation; The business accepting the terminal of data forwarding service under the terminal with wireless small station ability to work terminates; Because other reasons needs to close wireless small station mode of operation.
As shown in Figure 9, a kind of end that the embodiment of the present invention provides has the method flow diagram of the wireless small station mode of operation of the terminal of wireless small station ability to work, comprising:
