Description
Technical field
The present invention relates to a kind of bandwidth allocation methods, system and radio network controller, particularly a kind of WCDMA (Wide-band Code Division Multiple Access; WCDMA access system) bandwidth allocation methods, system and the radio network controller in the RRM of cell mobile communication systems.
Background technology
One of characteristics of WCDMA cell mobile communication systems are to use multiple speed rates multimedia service, because the difference of application scenarios, professional speciality, the transmission rate difference that different service types requires, its Qos (Quality of Service; Quality of service) requires difference.The type of service of WCDMA transmission can be divided into session service, stream business, interactive service and background service, wherein divide interactive service and background service all to have characteristics sudden, that the rate dynamic excursion is big, insensitive to propagation delay time, transmission bandwidth is not strict with; And session service, stream business need to distribute fixed-bandwidth to the delay requirement height, can not arbitrarily change.
The another one characteristics of WCDMA cell mobile communication systems are the differentiated service schemes (being the service quality that network preferentially guarantees high-end customer, high-priority service) that can provide complete, and operator can customize the service quality that this user can enjoy easily according to the user gradation of UE.
In the WCDMA cell mobile communication systems, radio network controller provides service carrier by setting up " RAB (RAB, Radio Access Bear) " related resource for cellphone subscriber's business.Has relation one to one between customer service and the RAB.Each professional foundation, core net sends to " distribution/maintenance attribute (ARP) " that will comprise this RAB in radio network controller " RAB assignment request " message, " distribution/maintenance attribute (ARP) " of RAB embodied the ability that this RAB obtained and held Internet resources, comprise following three parts: priority, seize ability, hold attribute, wherein:
Priority: the significance level that is used to identify this RAB;
Seize ability: be used for sign when Internet resources are nervous, whether can seize other users, it should be noted that, being seized the user must be " holding attribute " to be user's (hold the more popular address of attribute and can be " being seized attribute ") of " can be seized ", and this user of priority ratio is low;
Hold attribute: be used for the Internet resources that identifying user holds and whether allow to be seized by high-priority users.
Below we briefly introduce set up professional flow process in the RAB business in WCDMA communications, Fig. 1 is the professional schematic flow sheet of setting up of RAB in the WCDMA communication system, as shown in the figure, the professional foundation of RAB comprises following basic step:
Step 101, core net CN send " RAB assignment request (RAB ASSIGNT REQUEST) " message to radio network controller (RNC) and require to build RAB RAB business;
After step 102, radio network controller (RNC) are received this " RAB assignment request " message, set up Qos quality requirements such as professional type of service, speed according to request, initiate " radio link reconfiguration is prepared (RL RECONFIG PRE) " to NodeB;
Step 103, radio network controller (RNC) are received NodeB's " radio link reconfiguration ready (RLRECONFIG READY) " message;
Step 104, radio network controller (RNC) will be by the ALCAP signalings, and application Iub interface bandwidth resources are also carried out synchronously; The transfer resource form of carrying user data can be diversified between the NodeB/RNC, the AAL2 that uses during typically as ATM, UDP during IP network etc., here so-called application IUB interface band width resource is application AAL2 bandwidth resources when ATM, and when IP network, be application IP bandwidth resources;
After step 105, the Iub bandwidth resources application success, radio network controller (RNC) notice NodeB carries out " radio link reconfiguration is submitted (RL RECONFIG COMMIT) to ";
Step 106, radio network controller (RNC) send the wireless traffic carrying that " radio bearer is set up (RBSETUP) " message informing user equipment (UE) is set up carrying RAB business to user equipment (UE);
Step 107, user equipment (UE) return " radio bearer is set up and finished (RB SETUP COMPLETE) " message to radio network controller (RNC) and set up the wireless traffic carrying;
Step 108, at said process all after the success, radio network controller (RNC) returns " RAB assigns success response (RAB ASSIGNMENT RESPONSE) " message to core net CN.
In above-mentioned steps 104, radio base station controller by the application of ALCAP signaling to the Iub bandwidth resources be used for the bi-directional data of carrying between " UE-core net ", if this part bandwidth resources application/foundation failure, business data flow can't be sent to " NodeB/UE " from " opposite end/core net ", the data that UE sends to the opposite end also can't be sent to " core net/opposite end " from " UE/NodeB ", and this will cause business normally to use.
