Description
Technical field
The present invention relates to a kind of multi-signaling point system face Circuit management method and coding method, relate in particular in CDMA mobile communication system, base station controller (Base Station Controller, abbreviation BSC) management method and the coding method of land circuit (Circuit Identity Code is called for short CIC) under the environment of configuration multiple signaling points.
Background technology
Between base station controller (BSC) and mobile switching centre's (Mobile Switch Center is called for short MSC), exist many repeat circuits (E1), each bar E1 can be divided into 32 time slots, and the speed of each time slot is 64kbit/s.In general, the 0th time slot is a synchronization slot, and the 16th time slot allocation is the signalling system No.7 link, and remaining time slot allocation is done user's speech channel, is also referred to as land circuit CIC as the time slot of user session.The unique correspondence of each speech channel a CIC, and these CIC resources are shared by BSC and MSC.
Under traditional networking mode, signalling point SP of each BSC configuration (Signaling Point is called for short SP), this signalling point correspondence unique office direction (Office).Under the configuration of multiple signaling points, each BSC can support a plurality of signalling points, thus corresponding a plurality of office directions.But this is transparent for MSC, and the view of seeing in the MSC side is the corresponding base station of each signalling point, but these virtual base stations are to pool a real base station in reality realizes.
This has just brought the problem of management of CIC.Under the configuration of single signaling point, all the CIC resources between BSC and MSC all belong to an office direction, and each CIC has unique encoding, and as shown in Figure 1, the management of CIC is a mode of taking Unified coding under the single signaling point system.Under the configuration of multiple signaling points, BSC belongs to different office directions with CIC resource between MSC, as shown in Figure 2, requires the CIC of each office direction ownership to take the mode of absolute coding separately under the multiple signaling points system.CIC under each office direction is an absolute coding, and therefore the cic code under the different office directions can be the same.Such as 1 time certain bar CIC of office direction be encoded to 1000, exist too office direction 2 times to be encoded to 1000 CIC.
This brings difficulty to resource management, and as noted earlier, in fact these CIC belong to same BSC.In the data base set of BSC is unified transaction processing system, exist the processing of many relevant CIC, objectively require the coding of these CIC unique.Existing system generally is to add extra sign to CIC to the solution of this problem.As shown in Figure 3, the CIC standard coding format of A mouth agreement regulation, by pulse code modulation address (Pulse Code Modulation ID, be called for short PCM ID) and the time slot composition, sign indicating number outside this form is called in the middle of the present invention, i.e. the coded format of system outside is in the prior art, the CIC of sign indicating number coding adds extra sign outside above-mentioned, realizes that the cic code under the same BSC is unique.But this way to manage is general more loaded down with trivial details, and compatible relatively poor, is not easy to expand from existing system.

Embodiment
The objective of the invention is to have proposed a kind of multi-signaling point system face Circuit management method, this method is utilized the coded system of the inside and outside sign indicating number of CIC dexterously, simply and efficiently solved the coding collision problem of CIC under the multiple signaling points networking mode, simplified BSC inside to the difficulty that CIC manages, helped from the single signaling point system evolved to the multiple signaling points system.
In order to realize said method, the cic code that promptly is implemented among the same BSC is unique, the present invention is on agreement specified standard cic code method basis, a kind of new cic code method has been proposed, the notion of CIC ISN (Inner Code) and outer sign indicating number (Outer Code) has promptly been proposed, described ISN refers to the coded format of internal system, and promptly the reference format of described land circuit coding adds the coded format of the office direction coding of this land circuit; Described outer sign indicating number refers to the coded format of system outside, i.e. the reference format of described land circuit coding.Method of the present invention makes that the CIC resource code that is belonged under the different office directions among the same BSC is unique, thereby has solved the problem of conflict.
The present invention is achieved in that cic code is the integer of one 16 bit according to A interface protocol regulation, wherein represents time slot (0-31) for low 5, represents PCM ID for remaining high 11.Therefore a signalling point can dispose 2048 PCM at most.
If adopt the networking mode of many signalings, the telephone traffic of an original signalling point is shared by several signalling points, and the telephone traffic that need handle of each signalling point has just reduced like this, therefore no longer needs to dispose so much E1.In other words, the minimizing of the E1 number of each signalling point configuration means and can save the PCM ID needed bit number of encoding, and can reduce to 8 to the bit number of PCM ID from 11.Saved 3 bits can be brought the coding (1-7) that carries out office direction number.
Concrete grammar of the present invention as shown in Figure 4, reference format just outside the sign indicating number the basis on expand, high 3 bits of CIC are taken out as the office direction under the multiple signaling points system (Office) encode, the coded format of this internal system is called ISN in the middle of the present invention, the composition mode of such 1 CIC is: office direction number (3)+PCM ID (8)+time slot (5), the CIC of different office direction ownership has just accomplished that coding is unique.For the traditional group net mode of not supporting multiple signaling points, the coded system of CIC is constant.
The management method of CIC resource under the multiple signaling points system that the present invention proposes as shown in Figure 5, specifically describes as follows:
501, MSC sends the A mouth message of 1 forward direction to BSC, the information of carrying CIC in the message, and cic code be outer yard.
502, after BSC receives this message, convert the CIC in the message to ISN, the method for conversion is that the office direction of correspondence number is added on the outer sign indicating number of CIC.
503.BSC continue remaining Business Processing, finish some specific operation flow.
504. Business Processing finishes, BSC converts the CIC ISN to outer sign indicating number again.The method of conversion is that the CIC ISN is removed office direction number.
505.BSC send A mouth reverse message to MSC, the CIC that carries in the message is outer sign indicating number form.
Effect of the present invention is, so that under single signaling point and multiple signaling points system, the coding of CIC all is unique, has solved the puzzlement that the cic code conflict causes. BSC inside is identical to the way to manage of CIC, and the mode of outer code is transparent to MSC in this CIC, and this has reduced the cost from the single signaling point system to the multiple signaling points system evolved greatly. In the base station control that has been applied to actual cdma system (BSC) that the present invention is successful, and obtained good practical application effect.
