The present inventor recognizes, the new enhancement mode MAC layer model MAC-i/is that introduces will bring following technical problem to the management of E-DCH Active Set and the MAC layer model configuration of E-DCH.
On the one hand, because E-DCH adopts grand diversity (Macro Diversity Combining) technology, that is to say all residential quarters general while service-user equipment in the E-DCH Active Set, therefore, when E-DCH was configured to MAC-i/is, all residential quarters in the E-DCH Active Set all needed to support MAC-i/is.
On the other hand, the MAC layer model that each residential quarter in the communication system is supported may be different, and traditional MAC layer model MAC-e/es is only supported in some residential quarter, and some residential quarter is supported MAC-e/es and MAC-i/is simultaneously.
Thus, for example, be MAC-i/is and the residential quarter of E-DCH Active Set to be added only supports MAC-e/es not support under the situation of MAC-i/is at the current MAC layer model of E-DCH, if E-DCH is not reconfigured for the MAC-e/es pattern from the MAC-i/is pattern, then this residential quarter can't be added in the E-DCH Active Set.
Thereby one of purpose of the present invention is to provide a kind of mechanism that configures the MAC layer model for the E-DCH of subscriber equipment, and it can still can realize the configuration to the MAC layer model of E-DCH rightly under the different situation of the MAC layer model that each residential quarter is supported.
According to an aspect of the present invention, provide be used in a kind of network controller (RNC) in communication network in the described communication network, by the method for the enhanced uplink dedicated channel (E-DCH) of its subscriber equipment of serving configuration MAC layer model.Wherein, comprise the residential quarter for described enhanced uplink dedicated channel in the enhanced uplink dedicated channel Active Set of described subscriber equipment, the MAC layer model of described enhanced uplink dedicated channel is configured to traditional MAC layer model (MAC-e/es) or enhancement mode MAC layer model (MAC-i/is).Described method comprises:
A. receive the first trigger event, it indicates the first residential quarter can be for described enhanced uplink dedicated channel, and described the first residential quarter is not among described enhanced uplink dedicated channel Active Set;
C. in response to the first trigger event that receives, the current MAC layer model of judging described enhanced uplink dedicated channel is traditional MAC layer model or enhancement mode MAC layer model;
If the judged result among the step c is that described current MAC layer model is enhancement mode MAC layer model, then carry out the following step:
D. judge whether support of enhanced MAC layer model of described the first residential quarter;
E. according to the judged result in the described steps d, whether judgement changes described current MAC layer model.
Thus, network controller can be based on the current MAC layer model of E-DCH and the information such as MAC layer model that can support for the first residential quarter (residential quarter that can add the E-DCH Active Set) of E-DCH, adjudicate the MAC layer model that whether changes E-DCH, thereby can realize rightly the configuration to the MAC layer model of E-DCH.
According to the first embodiment of the present invention, in described step e, if described the first residential quarter support of enhanced MAC layer model is not then carried out the following step: judgement does not change described current MAC layer model.
In other words, when the first residential quarter support of enhanced MAC layer model and when only supporting traditional MAC layer model not, network controller determines this first residential quarter not to be joined E-DCH, need not thus to change the current MAC layer model of E-DCH, need not that namely it is reconfigured for the first residential quarter and support traditional MAC layer model.Thus, can significantly reduce the reconfiguring of the MAC layer model of E-DCH, reconfigure every expense of bringing, for example expense of signaling aspect thereby reduce.Especially, this embodiment is suitable for subscriber equipment and/or the communication system of having relatively high expectations aspect every expense reducing.
According to a second embodiment of the present invention, if described the first residential quarter support of enhanced MAC layer model is not then carried out the following step: judgement changes described current MAC layer model; Described current MAC layer model is reconfigured for traditional MAC layer model; Described the first residential quarter is added among the described enhanced uplink dedicated channel Active Set.
In other words, when the first residential quarter support of enhanced MAC layer model and when only supporting traditional MAC layer model not, network controller determines this first residential quarter is joined E-DCH, change thus the current MAC layer model of E-DCH, soon it is reconfigured for the first residential quarter and supports traditional MAC layer model, and subsequently the first residential quarter is joined among the E-DCH Active Set.Because the E-DCH Active Set has added new residential quarter, therefore can provide better service quality for subscriber equipment.Especially, this embodiment is suitable for subscriber equipment and/or the communication system of having relatively high expectations aspect service quality.
