Embodiment
The method of chain of command signalling in a kind of wireless system that the embodiment of the present invention provides, its technical scheme comprises:
Set up at least two signalling bearer path;
Select wherein transmission channel command transmitting;
Whether the state that detects this passage is normal, if normal, duplicate detection step; Otherwise, select other passages to carry out the transmission of this signaling from the bearer path of having set up.
Wherein, whether described detection can preferably use the described current bearer path of heartbeat mechanism detection to break down.Perhaps judgement does not receive whether the number of times of the response of same signaling reaches the value that presets, if be fault.Wherein, by known in the art, under wireless system, the chain of command signaling comprises the NBAP signaling that is applied between RNC and Node B, be applied in SCCP signaling between RNC and RNC, and ALCAP signaling etc.
Below in conjunction with accompanying drawing, the embodiment of the embodiment of the present invention is done further and elaborated.
As shown in Figure 2, it is for the signal transmission method FB(flow block) of the preferred RNC embodiment one of the present invention.The below illustrates the NBAP signaling that is applied between RNC and Node B, the method for transmitting under ATM or IP transmission means.When system supported ATM and two kinds of transmission meanss of IP simultaneously, the NBAP signaling was transmitted under ATM or IP transmission means and is comprised the following steps:
Step 201: set up the SAAL bearer path that transmits for the ATM mode and be used for the SCTP bearer path that the IP mode is transmitted between RNC and Node B.
Step 202: transmitting terminal selects a bearer path wherein to transmit the NBAP signaling.For convenience of description, suppose that transmitting terminal is RNC, what this RNC selected is SAAL bearer path command transmitting.
Step 203: utilize heartbeat mechanism detect the heartbeat of described SAAL bearer path or utilize other testing mechanisms commonly used in the transport layer of described RNC side, whether the state that detects described SAAL bearer path is normal.When the bearer path that described current transmission detected is normal, repeat this detecting step; Otherwise, execution in step 204 to 205.Wherein, described heartbeat mechanism belongs to and well known to a person skilled in the art content, therefore repeats no more here.
In addition, described detection also can not receive that the number of times of signaling response judges the state when prepass by calculating described RNC side, it is specially, described RNC judgement does not receive whether the number of times of the response of signaling reaches the value that presets, when described RNC does not receive the response of same signaling for several times by working as prepass one, and when this number of times reaches the value that presets, think that this passage breaks down.If this is during herein less than the described value that presets, RNC continues to repeat to send this signaling on former passage.As seen, at first the method needs to arrange the threshold values of not receiving response times.Described threshold values as the standard of judgement current channel state, for example, is three if threshold values is set, if the expression response of ining succession and all not receiving this signaling three times thinks that the bearer path of described this signaling of transmission breaks down.Described threshold values can be according to customer requirement, perhaps the experience value.
Step 204: the transport layer of described RNC the radio link layer that abnormal information is sent to this RNC side upper strata occurs with described SAAL bearer path.
Step 205: the radio link layer of described RNC selects the SCTP bearer path to carry out the transmission of this signaling.
The above-mentioned NBAP of being signaling transmits from the SAAL carrying embodiment that switches on the SCTP bearer path.In like manner, when the NBAP signaling is transmitted on the SCTP bearer path, when described SCTP bearer path breaks down, also can equally according to the method described above described NBAP signaling be switched to as on other bearer path such as SAAL bearer path.Because method is identical, repeat no more here.
Above-described embodiment is when the NBAP signalling, set up two transmission bearer passages and do mutually standbyly, when bearer path wherein interrupts, switch to another continuation transmission, thereby avoided the Transmission of this NBAP signaling, therefore improved the reliability of chain of command signalling in the wireless system.
Need to prove, the embodiment of the present invention is not limited to above-mentioned NBAP signaling, also can be applicable in the transmission of other chain of command signalings.Because the interface that different signalings are used is different, therefore according to different signalings, transmitting terminal and receiving terminal also are not limited only to the disclosed RNC of above-described embodiment and Node B, and for example technical solution of the present invention is also applicable to SCCP signalling between RNC and RNC:
For the SCCP signaling, if the system of described SCCP signalling supports ATM and two kinds of transmission meanss of IP simultaneously, so corresponding is selecting the M3UA bearer path, using the MTP3B bearer path under the IP transmission means under the ATM mode.In like manner, need to be before transmission SCCP signaling transmitting terminal and receiving terminal set up simultaneously MTP3B and M3UA carrying transmission channel.Transmitting terminal selects a passage wherein to carry out the transmission of SCCP signaling.When the transport layer of described transmitting terminal detected current selected passage and goes wrong, the upper strata of the described transmitting terminal of instruction (as radio link layer) selected another passage to transmit.Wherein, described detection mode also can detect by heartbeat mechanism or other testing mechanisms of corresponding signaling; Perhaps whether reach by the number of times that calculates the response of not receiving signaling the value that presets, judge whether work as prepass breaks down.

Step 302～step 303: a transmitting terminal selection bearer path wherein is as the main separation passage, and first-selected this main separation channel transfer NBAP signaling.For convenience of description, suppose that transmitting terminal is RNC, this RNC selects the SAAL bearer path as the main separation passage.
Step 304: utilize heartbeat mechanism detect the heartbeat of described SAAL bearer path or utilize other testing mechanisms commonly used in the transport layer of described RNC side, whether the state that detects described SAAL bearer path is normal.When described main separation bearer path (being the SAAL bearer path in the present embodiment) being detected when normal, repeat this detecting step; Otherwise, execution in step 305 to 306.Wherein, described heartbeat mechanism belongs to and well known to a person skilled in the art content, therefore repeats no more here.
In addition, described detection also can not receive that the number of times of signaling response judges the state when prepass by calculating described RNC side, it is specially, described RNC judgement does not receive whether the number of times of the response of signaling reaches the value that presets, when described RNC does not receive the response of same signaling for several times by working as prepass one, and when this number of times reaches the value that presets, think that this passage breaks down.If this is during herein less than the described value that presets, RNC continues to repeat to send this signaling on former passage.As seen, at first the method needs to arrange the threshold values of not receiving response times.Described threshold values as the standard of judgement current channel state, for example, is three if threshold values is set, if the expression response of ining succession and all not receiving this signaling three times thinks that the bearer path of described this signaling of transmission breaks down.Described threshold values can be according to customer requirement, perhaps the experience value.
Step 305: the transport layer of described RNC the radio link layer that abnormal information is sent to this RNC side upper strata occurs with described SAAL bearer path.
Step 306: the radio link layer of described RNC selects the SCTP bearer path to carry out the transmission of this signaling.
Step 307～step 308: whether the transport layer of described RNC continues to detect described main separation passage recovers normally, and when described main separation routing restoration was normal, described RNC selected this main separation passage to carry out the transmission of signaling; Otherwise, continue to detect.
