User terminal comprises the user terminal of different authorization types among the present invention, as CSG user terminal, non-CSG user terminal; The user terminal of different signatory grades, the user terminal of different service types.
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Embodiment one
This example is applicable to the range finding that CSG user terminal under the CSG-Open femtocell BS and non-CSG (non-CSG) user terminal carry out.
System configuration initial, switching, cycle, bandwidth request ranging region, so-called ranging region, selected running time-frequency resource zone when sending ranging code for user terminal, promptly user terminal should be carried on ranging code the zone of system's subframe.Different range finding purposes have disposed special-purpose ranging code collection.In this example, CSG user terminal and non-CSG user terminal are shared initial ranging zone and the set of initial ranging sign indicating number, CSG user terminal and non-CSG user terminal carry out initial ranging, to in the ranging code set, select ranging code at random, and selected ranging code is carried in the ranging region, by corresponding channel ranging code is sent to base station side, base station side is carried out signal time according to the ranging code that user terminal sent, frequency, the measurement of power, and definite time migration, frequency shift (FS) and power are adjusted parameter and are given user terminal, and user terminal is realized uplink synchronous according to adjusting parameter.Though, ranging region and ranging code set are identical, but the CSG user terminal is different with the selection mode of the ranging opportunity that non-CSG user terminal is adopted, Fig. 1 be selection mode and random back mode at random test machine can schematic diagram, as shown in Figure 1, in the radio bearer resources of sub-frame of uplink, each square frame is a radio bearer ranging opportunity among the figure, as radio bearer resources pieces such as OFDM (OFDM, Orthogonal Frequency Division Multiplexing) symbol and subcarriers.Selection mode is specially at random: from the t0 zero hour of subframe, the CSG user terminal selects for use a chance to carry the ranging code that the CSG user terminal is selected for use in preceding 1 to 6 chance (range finding time) from the ranging code set, and for the random back mode, then be provided with the rollback window, for example illustrate, its rollback window is 16, promptly from the t0 zero hour of subframe, non-CSG user terminal selects for use a chance to carry the ranging code that non-CSG user terminal is selected for use in preceding 1 to 16 chance from the ranging code set.Like this, because the duration of the chance of the selected carrying ranging code of non-CSG user terminal is more longer, ranging code be carried on subframe will the ranging code more selected than the chance of front than CSG user terminal to be carried on the more preceding position of subframe little, the rollback window of non-CSG user terminal is big more, and is just more little with the probability of CSG user terminal collision.
The network side provisional configuration can be passed through in CSG user terminal and the employed ranging opportunity of non-CSG user terminal zone, and notify user terminal by system broadcast message, described system broadcast message can be by one or more son bag carrying of auxilliary superframe head, for example, pass through system's targeting sequencing and broadcast at user terminal, judge own current when being the CSG user terminal, to determine that employed ranging opportunity zone and ranging opportunity selection mode are selection mode at random, when being defined as non-CSG user terminal, will determine that employed ranging opportunity zone and ranging opportunity selection mode are the random back mode.Also different ranging opportunity selection modes can be set according to other priority levels of user terminal, for example, the user terminal that can be high priority is selected ranging opportunity with selection mode at random, the user terminal of inferior high priority to the user terminal of low priority is all selected ranging opportunity in the random back mode, and the user terminal of inferior high priority to the rollback window of the selected random back mode of the user terminal of low priority increases successively; Perhaps, for user terminal to the user terminal of low priority of high priority is all selected ranging opportunity in the random back mode, and the user terminal of high priority to the rollback window of the selected random back mode of the user terminal of low priority increases successively; Perhaps, all user terminal is all selected ranging opportunity with selection mode at random; Perhaps, all user terminals are all selected ranging opportunity in the random back mode, and the rollback window size of selected random back mode is identical.
By system broadcast information initial, switching, cycle, bandwidth request ranging region information and ranging code set are notified to user terminal.Described system broadcast message can be by one or more son bag carrying of auxilliary superframe head.When aforesaid ranging region is determined in whole system, perhaps, after the ranging code set is all determined, with ranging region and ranging code set configuration in user terminal, user terminal is selected a ranging code at random in the ranging code set of being disposed, and selects a chance carrying ranging code in the ranging region that is disposed in current ranging opportunity length (zone) at random.
The CSG user terminal adopts selection mode at random in the initial ranging zone, the non-CSG user terminal adopts the random back mode to select a ranging opportunity in the initial ranging zone, and in the ranging code set that is distributed separately, select a ranging code at random, on selected ranging opportunity, send selected ranging code/and carry range finding message then, find range.Comprise type of user terminal sign and/or bandwidth request information and/or range finding purpose information in the range finding message.The type of user terminal sign comprises CSG user type and non-CSG user type etc., is used for the type of base station discriminating user, determines the priority-level of user terminal, thereby implements different processing modes.
When user terminal is received the base station to the response of the initial ranging of its transmission, if the state of response is " continuation ", CSG user terminal and non-CSG user terminal adopt the mode of selecting at random to select a ranging opportunity in the cycle ranging region on one or more subframes.Then, user terminal is selected a ranging code again at random in the corresponding ranging code set that is distributed separately, and sends selected ranging code and/or carry range finding message on selected ranging slot, continues to carry out range finding.
When described user did not receive the base station to the response of the ranging code of its transmission, user terminal thought and the range finding failure enters competition solution process that concrete mode is as follows:
The CSG user terminal adopts selection mode or random back mode at random in the initial ranging zone, the non-CSG user terminal adopts the random back mode or doubles the rollback window in the initial ranging zone random back mode is reselected a ranging opportunity; Then, user terminal is selected a ranging code again at random in the corresponding ranging code set that is distributed separately, and sends selected ranging code and/or carry range finding message on selected ranging slot, range finding again.
When the base station present load is too high, can refuse the continuation ranging process of part low priority user terminal.When non-CSG user terminal ranging code is received in the base station, if the load of current system reaches certain thresholding, the base station can be one of following form to the response of non-CSG user terminal, and is not limited to following form: state is designated as " continuation ", and indicating user terminal can continue to carry out range finding; State is designated as " abandoning ", and indicating user terminal should stop range finding;
Competition solution process is carried out repeatedly, and the rollback window under the random back mode is that the factor enlarges with 2 the inferior power of n (n＞=1), until the user terminal ranging success.
Among the present invention, also can different ranging code collection be set by concentrating at the initial ranging sign indicating number for the user terminal of different priorities, described user terminal is concentrated at its corresponding ranging code and is selected ranging code at random.Avoid or reduce collision between the different priority users terminal by the difference of ranging code, determine the priority of user terminal, make corresponding range finding according to this and handle.Here, different ranging code collection comprise: the high-priority users terminal is used initial ranging sign indicating number collection, the ranging code collection of low priority user terminal is the subclass of the ranging code collection of high-priority users terminal, perhaps, the low priority user terminal is used initial ranging sign indicating number collection, the ranging code collection of high-priority users terminal is the subclass of the ranging code collection of low priority user terminal, and perhaps, the ranging code collection of high-priority users terminal and the ranging code collection of low priority user terminal are independent mutually.By the setting of ranging code collection, reduce or avoid the collision probability of low priority and high-priority users terminal.
Among the present invention, also can be by distribute the running time-frequency resource of different range finding usefulness for the user terminal of different priorities.By the running time-frequency resource difference of carrying ranging code, avoid the collision between the different priority users terminal, the priority of user terminal can be determined in the base station simultaneously, makes corresponding range finding according to this and handles.
