Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the accompanying drawings and the specific embodiments.
Fig. 1 is the schematic flow sheet of the opening base station method of one embodiment of the invention.As Fig. 1, the opening base station method of one embodiment of the invention comprises the steps:
Step 101 when base station initiated or chain rupture, judges in the E1 link between base station side and radio network controller (RNC, the Radio Network Controller) side whether have an E1 path that can carry out data communication at least; In this way, then execution in step two, otherwise, process ends;
Step 102, the transmission parameter of radio network controller side Remote configuration base station side, and with the configuration transmission parameter transfer to base station side by above-mentioned at least one E1 path;
Step 103, base station side receives the transmission parameter of radio network controller side transmission, is provided with according to above-mentioned transmission parameter, and is connected to the radio network controller side after being provided with.
In specific implementation, the radio network controller side can be the machine room side of placing radio network controller and management station.
In this embodiment, transmission parameter can be the IMA link parameter, as comprises: IMA group is provided with, the way of whether scrambling, E1 link, build-out resistor etc.
In the communicating by letter of base station side and RNC side, the parameter that the IMA interface need dispose is more, if base station and RNC are inconsistent with some parameter configuration, then can cause IMA can't enter operating state or state of activation, thereby base station side also just can't have been communicated by letter with the RNC side, particularly, as operation or configuration mode parameter, ima protocol version number, clock module etc.And under the minimum transfer condition, can be when not starting the connection of IMA layer protocol earlier with the simple physics passage of one of an E1 path setting, so just can between base station side and RNC side, simply communicate by letter earlier, can give Remote configuration well correct transmission parameter in base station in the machine room side earlier by this E1 path, as the IMA link parameter, and then start IMA, just can guarantee that IMA starts successfully, and the trouble of the last station modification parameter of having avoided sending someone.
Fig. 2 is the schematic flow sheet of the opening base station method of another embodiment of the present invention.As Fig. 2, the opening base station method of another embodiment of the present invention comprises the steps:
In this embodiment, the machine room side can be RNC side configuration transmission parameter before or after the transmission parameter of Remote configuration base station side, and be connected the needs of setting up with base station side for satisfying the machine room side, the machine room side can be consistent with the transmission parameter of base station side and the transmission parameter settings of RNC side.
Further, in this embodiment,, then return execution in step 201, regain the process of transmission parameter if the transmission of base station side and machine room side is interrupted.
Having set up transmission channel in base station side and RNC side is after IMA is communicated with, and the foundation of IPOA passage can carry out between base station side and the RNC side that subsequent parameter ground is provided with and operation such as edition upgrading between base station side and the RNC side.
Utilize method of the present invention, as long as possessed the minimum transfer condition between base station side and the RNC side, promptly had at least one can carry out the E1 path of data communication the time, it is consistent the parameter of RNC side and base station side to be set automatically in the machine room side, and can upgrade the setting of base station side transmission parameter after link breaks down as loopback or trouble shooting automatically by this E1 path.Thereby, loopback has appearred in multichannel E1, also be unlikely to cause chain rupture.In an embodiment of the present invention, can seek mechanism and detect the E1 link that loopback whether occurs by increasing loopback between a RNC side and the base station side, and when detecting the E1 link of loopback, this loopback of mark E1 link, so that itself and remaining, non-loopback, normal E1 link difference are come, and utilize remaining, non-loopback, normal E1 link execution in step 201 simultaneously, with by step 201 new transport parameters more, and the transmission that keeps base station side and RNC side.Wherein, loopback is meant the data of coming from a direction, has beamed back to former state again.
Exemplarily, can realize the detection or the detection of loopback by the following method: preestablish special message, all send special message in base station side and/or RNC side, then and after receiving the special message that corresponding opposite end sends return the predetermined message different with this message that receives, thereby, if the E1 link is loopback not, then the message received of base station side and/or RNC side joint is different with the message of transmission; Conversely, if E1 link loopback, then the message received of base station side and/or RNC side joint is identical with the message of transmission.Therefore, by judging the whether identical E1 of detecting link loopback whether of first message that base station side and/or RNC side send and second message that receives.Wherein, the corresponding opposite end of base station side is the RNC side, and the corresponding opposite end of RNC side is a base station side.After to all E1 link detecting, which road E1 link just knows has by loopback.In specific implementation, can be with behind the detected E1 link mark, and forbid falling, influence the communication of other E1 link in the IMA group to prevent it.
Further, when having the loopback E1 link that has been labeled, the method for the embodiment of the invention can further regularly be inquired about these loopbacks E1 link and whether removed loopback, can in time add IMA group participation communication so that removed the E1 link of loopback.Particularly, one timer can be set, periodically start and seek or inquire about E1 link loopback and whether be disengaged, as being disengaged, and this moment IMA group utilized E1 link establishment those non-loopbacks, normal the base station be connected with the normal of RNC side, be that the IMA new transport parameters of communicating by letter more dynamically adds IMA again with the E1 link that will remove loopback and organizes then by the inverse multiplexing link communication of RNC by the asynchronous transfer mode set up; As the normal connection of foundation of IMA group this moment, then can come undated parameter by execution in step 201.Exemplarily, owing to artificial processing, this loopback has been cancelled during the releasing of E1 link loopback possibility.
In specific implementation, can be set as required the opportunity of carrying out loopback link detection or detection, as can after base station initiated, promptly beginning to carry out, and in base station side and process that the RNC side is communicated by letter, regularly carry out.And can adopt trigger mechanism to trigger this loopback detection.Exemplarily, RNC and base station independent triggers separately can be set.Wherein, the triggering of RNC side can be waited for when the base station is connected on the RNC after the associated transport parameter that has been configured the base station on the RNC side, triggered loopback detection; When the triggering of base station side can start the back in the base station for the first time and not dispose the IMA parameter as yet, trigger loopback detection, and/or, trigger when restarting the back first time of in the transmission of base station and RNC side, having no progeny and not disposing the IMA parameter as yet.
