Description
Technical field
The present invention relates to a kind of method of the Iub of raising message reliability of signaling link.
Background technology
In Wideband Code Division Multiple Access (WCDMA) (the Wideband Code Division Multiple Access:WCDMA) cell mobile communication systems, B node applying portion (Node B Application Part:NBAP) is finished the controlled function of Iub mouth, comprises common part and private part.Wherein the message of common part sends by Node B control port (Node B Control Port:NCP) link among the NBAP, and private part message sends by Communication Control port (Communication Control Port:CCP) link.Agreement regulation radio network controller (Radio Network Controller:RNC) has only a NCP port to a NodeB, but a plurality of CCP ports can be arranged.
In the realization of present 3G equipment vendors, the corresponding transmission bearer link of NCP port, the also corresponding transmission bearer link of CCP port, the transmission bearer link can be AAL5 signaling link or IP bearing link, which CCP port each subscriber equipment (User Equipment:LE) uses distributed by Node B when Radio Link is set up, and its logical construction is with reference to the accompanying drawings shown in 1.When the NCP link was disconnected, all common signalings can't carry out between Node B and RNC alternately, and all use the relevant dedicated signaling of UE of this CCP also can't carry out between Node B and RNC alternately when the CCP link is disconnected.Although AAL5 signaling link or IP bearing link have functions of retransmission, under the disconnected situation of link, can't guarantee to carry out effective transmission of messages between RNC and the Node B, Iub message makes the reliability of link also not high.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method of the Iub of raising message reliability of signaling link.
In order to reach the foregoing invention purpose, the present invention adopts following technical scheme:
A kind of method that improves Iub message reliability of signaling link is applied to may further comprise the steps in the WCDMA cell mobile communication systems:
In the data configuration of RNC and Node B two transmission links of NCP port arrangement;
Set up two above-mentioned transmission bearer links during system start-up, the setting one is a primary link, and another is a reserve link;
Transmitting terminal occurs switching to another reserve link when unusual at a link, uses this reserve link to send signaling message, and receiving terminal receives signaling message simultaneously on two links.
This method also comprises the steps: further
In the data configuration of RNC and Node B two transmission links of each CCP port arrangement;
Set up two above-mentioned transmission bearer links during system start-up, the setting one is a primary link, and another is a reserve link;
Transmitting terminal occurs switching to another reserve link when unusual at a link, uses this reserve link to send signaling message, and receiving terminal receives signaling message simultaneously on two links.
Compared with prior art, adopt method of the present invention, can guarantee under the unusual situation of signaling link, to automatically switch to another signaling link, guaranteed normally carrying out of RNC and Node B Signalling exchange, improve the reliability that Iub message makes link greatly.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further detailed, but not as a limitation of the invention.
Embodiment one:
With reference to figure 2, make the logical model figure of link for the Iub message of present embodiment one, in the data configuration of RNC and Node B, be two transmission links of NCP port one configuration, set up two transmission bearer links during system start-up, when transmitting terminal another reserve link occurs switching to when unusual at primary link, use this reserve link to send signaling message, receiving terminal can receive signaling message simultaneously on two links.
Embodiment two:
With reference to figure 3, make the logical model figure of link for the Iub message of the embodiment of the invention two, in the data configuration of RNC and Node B, respectively dispose two transmission bearer links for NCP port one and each CCP port 2, set up above-mentioned two transmission bearer links during system start-up, transmitting terminal another reserve link occurs switching to when unusual at a link, use this reserve link to send signaling message, receiving terminal receives signaling message simultaneously on two links.
With reference to shown in Figure 4, for the foregoing description one and embodiment two, in system start-up, set up corresponding dual link after, it is as follows that Iub mouth transmitting terminal uses dual link to send the performing step of signaling message:
Step 101: determine that a link is a primary link, another link is a reserve link;
Step 102: wait Iub message order to be sent;
Step 103: judge whether to need to send the order of Iub message, if, then carry out next step 104, if not, then return Iub message orders to be sent such as step 102 continues;
Step 104: judge whether current primary link is normal, if normal, then execution in step 105, if undesired, then execution in step 106.
Step 105: on current primary link, send the order of Iub message, return step 102 then and continue to wait for that sending Iub message makes next time;
Step 106: judge whether current reserve link is normal, if normal, then execution in step 109, if undesired, then execution in step 107;
Step 107: the Iub message that abandoning this time needs to send makes, and alarms, and discharges the corresponding resource of unusual link, carries out next step 108;
Step 108: making repeated attempts rebulids unusual link, and after the normal foundation of a unusual link, this link promptly changes current primary link into, return execution in step 102, if also there is another unusual link, continue to attempt rebuliding, after success, also return execution in step 102;
Step 109: send the order of Iub message on this reserve link, simultaneously this reserve link is become current primary link, former primary link becomes current reserve link, makes repeated attempts to rebulid unusual link, returns step 102 simultaneously.
With reference to figure 5, among the present invention in system start-up, set up corresponding dual link after, it is as follows that Iub mouth receiving terminal uses dual link to receive the performing step of signaling message:
Step 201: judge whether current primary link is normal,, then carry out next step 202 if normal, if unusual, then direct execution in step 203;
Step 202: on current primary link, receive Iub message and make message, continue to carry out next step 203;
Step 203: judge whether current reserve link is normal,, then carry out next step 204 if normal, if undesired, then direct execution in step 205;
Step 204: on current reserve link, receive Iub message and make message, and continue to carry out next step 205;
Step 205: judged whether unusual link, if two link is unusual link, then carry out next step 206, if one link is unusual link, another is a normal link, then normal link is returned step 201, simultaneously to unusual link, carry out next step 206,, then directly return step 201 if there is not unusual link;
Step 206: make repeated attempts and create unusual circuit again, after success, return step 201
As seen, can not distinguish primary link and reserve link, to the message equivalent processes of two links receptions at receiving terminal.
The present invention is in implementation process, if because system resource constraints is when causing creating reserve links for all NCP port ones and CCP port 2, can be referring to the method for embodiment one, only the NCP port one is created reserve link, because that the influence of NCP port one is whole Node B, and all UE that are to use this CCP port 2 of CCP port 2 influences.
Adopt method of the present invention, can overcome in the prior art NCP port one and CCP port 2 links effectively and have no progeny, between RNC and Node B, can't carry out the shortcoming of Signalling exchange, increased the reliability that Iub message makes link widely.
