Embodiment
Fig. 1 is the flow chart of interconnection method for base station embodiment one of the present invention, and as shown in Figure 1, the method for the present embodiment can comprise:
Step 101, source base station receive the business request information that source user equipment sends, and comprise asked business information and the identification information of target UE in described business request information.
When source UE needs to carry out service data interaction with object UE, source UE can send business request information to the source base station at its place, can comprise asked business information and the identification information of object UE in this business request information.Wherein, this business information can describe the service attribute feature that source UE needs the service data interaction carried out with object UE, for example, it is the video data transmission that data volume is larger that this business information can describe the service data interaction that namely will carry out, or the short message transmission that data volume is less, or other service data interaction type.
Step 102, described source base station set up interconnected put-through channel, to transmit business datum mutual between described source user equipment and target UE on described interconnected put-through channel according to the target BS at demand for interconnection parameter corresponding to described business information and described target UE place.
Source base station, after receiving this business request information, can determine the demand for interconnection parameter that this business information is corresponding according to the business information comprised in this business request information.
Specifically, according to business information, source base station, after receiving this business request information, can be known that source UE needs to be about to the type of the service data interaction carried out between object UE, thus determine the demand for interconnection parameter that the type of this service data interaction is corresponding.This demand for interconnection parameter needs to set up the interconnected put-through channel meeting this demand for interconnection parameter, to ensure with the data interaction of certain mass finishing service with target BS for characterizing source base station.The present embodiment does not limit the particular content of this demand for interconnection parameter, as long as can to ensure on the interconnected put-through channel that business datum can be set up between source base station and target BS with certain mass alternately.It should be noted that, the network quality demand that those skilled in the art can realize required for it sets demand for interconnection parameter, to ensure the transmission quality of the interconnected put-through channel set up between source base station and target BS.Comparatively common demand for interconnection parameter can for completing bandwidth, time delay, quality of service (the Quality of Service needed for this service data interaction, hereinafter referred to as: QoS), enriching constantly facing to type of service, this demand for interconnection parameter also can be enriched thereupon.
For example, source UE needs to carry out video traffic data interaction with object UE, and therefore, source UE can send business request information to source base station, and the business information comprised in this business request information can describe this video traffic.Source base station is after this business information of acquisition, know that source UE and object UE are about to carry out the mutual of video traffic data, and for video traffic, bandwidth shared by it may be larger, and, user may be more responsive to the time delay of video data, therefore, the demand for interconnection parameter corresponding with video traffic can comprise bandwidth sum time delay, be understandable that, QoS equally also can consider as demand for interconnection parameter by those skilled in the art, or also can add other demand for interconnection parameter to ensure the transmission quality of these video traffic data.Be understandable that, for common short message service, if the demand for interconnection parameter of its correspondence is also bandwidth sum time delay, then the bandwidth needed for this video traffic should be greater than the bandwidth needed for short message service, and the time delay needed for video traffic should be less than the time delay needed for short message service.Therefore, those skilled in the art can preset the size for the demand for interconnection parameter corresponding to different service types.
After source base station determination demand for interconnection parameter, this source base station can set up interconnected put-through channel according to the target BS at this demand for interconnection parameter and object UE place, thus make to set up interconnected put-through channel and can meet this demand for interconnection parameter, further guarantee source UE and object UE carry out the reliability of data interaction on this interconnected put-through channel.The interconnected put-through channel set up based on demand for interconnection parameter, relative to prior art, can be avoided the problem of service data loss or communication disruption, improve network service quality.
The present embodiment, source base station can with demand for interconnection parameter for foundation sets up with target BS the interconnected put-through channel meeting this demand for interconnection parameter, this interconnected put-through channel can provide for source UE and object UE the data transmission channel having certain mass and ensure, thus when making source UE and object UE carry out service data interaction on this interconnected put-through channel, avoid the problem of service data loss or communication disruption as far as possible, improve network service quality.
