In the embodiment shown in fig. 1, between Node B 16 and portable terminal (as UE1 and UE2), also exist the control channel of non-special use, between UE, only exist Traffic Channel.Therefore, cordless communication network can be controlled the P2P communication of charging.About such P2P communication, the China national application number of submitting on March 7th, 2003 is 03119892.9 application people for Koninklijke Philips Electronics N.V and applicant's file number are in the patent application that is entitled as " method and apparatus of setting up the point-to-point peer-to-peer communications in the cordless communication network " of CN030003 detailed description to be arranged, and the disclosure of this patent application is with incorporated herein by reference.
As shown in Figure 1, when receiving from being used for after the request that another portable terminal makes a call an of portable terminal, UTRAN will check whether these two UE have applied for the P2P communication service.If two UE have applied for the P2P communication service, if so feasible, UTRAN will help these two UE to set up the P2P communication linkage, and the discount information of relevant P2P communication service is offered two UE.The user can select whether to utilize the P2P communication service.If two users determine to use the P2P communication service, as rewarding, two users will only need the part of payment ordinary disbursements so.Below, will describe the process of the P2P communication of managing by UTRAN in conjunction with Fig. 2 in detail.
After user terminal UE start, this UE searches signal from UTRAN via Broadcast Control Channel (BCCH) in a sub-district.UTRAN will receive from the register information of the renewal of UE (step S102).If the user has applied for the P2P communication service, the user can be default mode or prompt modes with the mode of operation setting (or pre-seting) of P2P communication service so.Under default mode, when this UE begins a calling or receives a calling, select the P2P communication service to select automatically as first of communication.But under prompt modes, no matter whenever this UE begins a calling or receives a calling, and this UE will receive an information that comes from UTRAN, select the P2P communication service with prompting.Can be set to a kind of pattern in two kinds of patterns at the concrete period.
When UE sends when calling out, it at first sends to UTRAN with a request that is used to start this calling.Can comprise the P2P connection request in this request.Receiving this request (step S106) of start calling out afterwards, UTRAN can be regardless of the P2P connection request that whether has from this UE, attempts automatically in call initiator and receive between the UE setting up a P2P communication linkage.UTRAN checks at first whether two UE have all applied for P2P communication service (step S108).Then, UTRAN judges whether two UE all are suitable for using P2P communication service (step S112).If any one UE is because for example this UE is not suitable for P2P communication not in the range for wireless communication that P2P signal post supports, UTRAN will provide conventional communication service (step 114) to two UE so.
On the other hand, use the P2P communication service if two UE are applicable to, UTRAN will judge that each UE has selected the default mode or the prompt modes (step S116) of P2P communication service so.If there is a UE to select prompt modes, UTRAN will and select the incentive message of P2P communication service together to send to that UE (step 122) about the user an information so.This award can be discount, returning or incentive reward voucher.Discount can be calculated based on the increase of power system capacity and the statistics profit that minimizing brought of sub-district overall interference.In a predetermined time duration, discount rate can also be along with the actual traffic load situation in the sub-district or annoyance level and is changed.For example, if business load is very big, the discount rate of P2P communication service may be higher so.And the user of participation data, services can obtain the award of special discount by the P2P link.
UTRAN receive from this UE selection (step S126) afterwards, judge whether this UE has selected P2P communication service (step S132).Do not select the P2P communication service if having a UE among two UE at least owing to for example relate to the QoS under the important call situation (service quality), UTRAN will provide conventional communication service (step S114) for two UE so.On the other hand, if two UE have selected P2P communication service or two UE to select the default mode of P2P communication service, UTRAN will divide between these two UE and be used in the resource (step S136) of setting up the P2P link so.Three included steps of dotted line in the UE execution graph 2 then.Particularly, UE will carry out the detection (step S141) of P2P link to judge whether to obtain P2P link (step S141).If can not obtain the P2P link, UTRAN will regain the P2P communication resource (step S152) so, and provide conventional communication service (step S114) to UE.But if can obtain the P2P link, UE will begin to carry out P2P communication (step S154) so.
After P2P communication is finished and has been discharged the P2P communication resource, UTRAN is recorded in the information of relevant P2P communication service in Home Location Register (HLR) and the Visited Location Registor (VLR) 26 (step S154), and the paying information after will giving a discount sends to UE, consults relevant expense (step S162) to allow the user at once.
In the superincumbent description, illustrate the present invention in conjunction with a UTRAN system always.Yet, be not limited to this system.In fact, any wireless communication system can use in conjunction with the present invention.
