DESCRIPTION
Treatment resource management procedure in a mobile radiocommunication system.
The present invention refers generally to mobile radio communication systems and more particularly to systems that use the CDMA technique (for "Code Division Multiple Access" in English, Multiple Access by Code Division, in Spanish).
The CDMA technique is used, especially, in so-called third generation systems, such as, especially, the UMTS system (from “Universal Mobile Telecommunication System” in English, Universal Mobile Telecommunications System, in Spanish).
In general, a mobile radio communication network comprises, as recalled in FIG. 1, a set of base stations and base station controllers. In the UMTS system, this network is also called UTRAN, from “UMTS Terrestrial Radio Access Network”, the base stations are also called Node Bs, and the base station controllers are also called RNCs. (from "Radio Network Controller" in English, Radio Network Controller, in Spanish).
The UTRAN network is in relation, on the one hand, with mobile stations (also called user equipment or "User Equipment" or UE), by an interface called "Uu" interface and, on the other, with a network core, or CN (from "Core Network in English"), by an interface called "UI" interface.
As recalled in figure 1, the RNCs are linked:
- to Node Bs through an interface called the “Iub” interface,
- between them through an interface called the “Iur” interface,
- to the network core CN through an interface called the "Iu" interface.
For a given Node B, the RNC that controls it is also called CRNC (for “Controlling Radio Network Controller” in English) and, therefore, it is linked to this Node B through the “Iub” interface. The CRNC has a function of load control, and of control and allocation of radio resources for the Node Bs that it controls.
For a given communication relating to a given user equipment UE, there is an RNC, called SRNC (for "Serving Radio Network Controller") which is connected to the network core CN through the interface "Iu". The SRNC has a control function for the considered communication, including functions of adding or removing radio links (according to the macro-diversity transmission technique), of control of parameters susceptible to change during the communication, such as flow, power, spreading factor, ... etc.
In CDMA systems the capacity limitations on the radio interface are fundamentally different from what they are in systems that use other multiple access techniques, such as, especially, the TDMA technique (for “Time Division Multiple Access” in English, Multiple Access by Time Division, in Spanish). The TDMA technique is used especially in the so-called second generation systems such as the GSM system (from "Global System for Mobile Communications" in English, Global System for Mobile Communications, in Spanish). In CDMA systems, all users share the same frequency resource at all times. The capacity of these systems is therefore limited by interference, and for this reason these systems are also called "soft limited systems".
For this reason, in CDMA systems, algorithms such as algorithms called load control algorithms (or "load control" in English) are envisaged to prevent overloads, detect them and, if necessary, correct them, in order to avoid a degradation of the load. quality, and algorithms called call admission control (or "call admission control" in English), to decide if the capacity of an unused cell at a given moment is sufficient to accept a new call in this cell (depending on various parameters such as the service required for this call, ... etc). In the following, these various algorithms will also be regrouped in the general form of load control.
Usually these algorithms use only two radio criteria that are usually implemented in the CRNC, which does not have information on the processing capacity of the Node Bs that it controls. Under these conditions, it may occur, for example, that the CRNC accepts a new call, and then finally rejects it due to the lack of processing resources at Node B, which unnecessarily implies additional processing at the CRNC and additional signaling exchanges between the CRNC and Node B.
Naturally, it will be possible to avoid these drawbacks by providing in Node B enough treatment resources to cover all cases, including the case of maximum capacity (corresponding to the case of low level of interference). But this would lead to expensive and most often oversized base stations. Furthermore, in the case of progressive introduction of the services offered by these systems, the processing capacity of the base stations may be limited at the beginning of the commissioning of these systems and be progressively increased thereafter.
ES 2 302 786 T3
Thus, it would be desirable to take into account the processing capacity of the base stations (or Node Bs) for load control in such a system.
Figures 2 and 3 recall the main treatments used, respectively, in transmission and reception, in a base station such as, especially, a Node B for the UMTS system.
In figure 2 an emitter 1 is illustrated comprising:
- encoding means-channel 2,
- widening means 3,
- means of radio-frequency emission 4.
These different treatments are well known to those skilled in the art, and need not be described again in detail here.
In a known manner, channel-coding uses techniques such as error-correcting coding and interleaving, which make it possible to obtain protection against transmission errors.
The coding (such as coding with error correction) is intended to introduce redundancy in the transmitted information. The coding rate is defined as the ratio between the number of bits of information to be transmitted and the number of transmitted bits or coded bits. By using different types of error correcting codes, different levels of quality of service can be obtained. For example, in the UMTS system, for a first type of traffic (such as high throughput data) a first type of error correcting code consisting of a turbocode is used, and for a second type of traffic (such as low throughput data throughput or voice) a second type of error correction code is used, consisting of a convolutional code.
Channel-coding also generally includes a throughput adaptation designed to adapt the throughput to be transmitted or throughput offered for transmission. Flow adaptation may include techniques such as repetition and / or punching, with the flow adaptation rate then being defined as the repetition and / or punching rate.
The gross throughput is defined as the throughput effectively transmitted through the radio interface. The net flow is the flow obtained after deducting from the gross flow everything that is not useful for the user, such as, especially, the redundancy introduced by the coding.
Spreading uses the known principles of spectrum spreading. The length of the spreading code used is also called the spreading factor.
It is recalled that in a system such as, especially, the UMTS, the net flow rate (also referred to more simply in the following as "flow rate") may vary during the same communication, and that, in addition, the Spread factor can vary depending on the flow to be transmitted.
In figure 3 a receiver 5 is illustrated comprising:
- radio-frequency reception means 6
- means 7 for estimating the received data, which in turn comprise, in particular, de-spreading means 8 and channel-decoding means 9.
These different treatments are equally well known to those skilled in the art and therefore do not need to be described again in detail here.
Figure 3 illustrates an example of treatment that can be put into practice in the de-spreading means 8. This treatment corresponds in this case to the treatment put into practice in a Rake-type receiver, which makes it possible to improve the quality of data estimation received, exploiting the multipath phenomena, that is, the propagation of the same source signal along multiple paths, obtained, especially, by multiple reflections on elements of the environment. In contrast, in CDMA systems, especially TDMA systems, these multipaths can, in effect, be exploited to improve the quality of the estimate of the received data.
A Rake receiver comprises a set of L fingers (or “fingers” in English) indicated by 10<sub>1</sub> to 10<sub>L</sub>, and means 11 for combining the signals from these different fingers. Each finger makes it possible to de-spread the received signal according to one of the different paths taken into account, the different paths taken into account being determined by means 12 to estimate the impulse response of the transmission channel. The means 11 make it possible to combine the despread signals corresponding to the different paths considered, according to a treatment intended to optimize the quality of the estimation of the received data.
ES 2 302 786 T3
The reception technique by means of a Rake receiver is also used in conjunction with the macro-diversity transmission technique, according to which the same source signal is transmitted simultaneously to the same mobile station by several base stations. The macro diversity transmission technique allows, not only to improve the reception characteristics, by means of a Rake receiver, but also to minimize the risks of call loss during intercellular transfers, or "handovers" in English. For this reason, it is also called "soft handover" (in English), as opposed to the "hard handover" technique according to which a mobile station is connected at any given time to only one base station.
The means of estimating the received data may, furthermore, use various techniques aimed at reducing interference, such as, for example, the so-called multi-user detection technique (or "multi-user detection" in English).
It is also possible to use a plurality of reception antennas. The means for estimating the received data then further comprise means for combining the signals obtained at these different reception antennas, also in order to optimize the quality of the estimation of the received data.
Channel-decoding includes functions such as deinterleaving and error-correcting decoding. Error-correcting decoding is generally significantly more complex than error-correcting coding and can use techniques such as maximum likelihood decoding. For example, for convolutional codes, a so-called Viterbi algorithm can be used.
In order to be able to handle several users simultaneously, a base station or Node B comprises a set of transmitters and receivers such as the transmitter and the receiver thus remembered. Thus, in a base station or Node B a great processing capacity is required, especially in reception, for the estimation of the received data.
Thus, as indicated above, it is desirable to take into account the throughput of a base station, for load control in a system such as, for example, the UMTS system.
Thus, for the UMTS system, in the document 3G TS 25,433 published by the 3GPP (“3<sup>rd</sup> Generation Pertnership Project ”), it is specified that Node B indicates to the CRNC its global treatment capacity (called“ capacity credit ”), and the amount of this global treatment capacity, or cost, for each value of the spreading factor (or“ spreading factor ”in English, or SF) possible on this system. The set of costs for the different possible values of the spreading factor is also called the capacity consumption law. Such information is signaled by a Node B to the CRNC each time the processing capacity of this Node B changes, using a message called "Resource Status Indication", or in response to a request from the CRNC using a message called "Audit. Response ”.
The CNRC then updates the remaining credit, based on the consumer law, especially in the UMTS system:
- for dedicated channels, during the procedures of establishment, addition, elimination, or reconfiguration, of a radio link (or in English, “radio link set-up”, “radio link addition”, “radio link deletion”, “radio link reconfiguration ”) such as those defined in document 3G TS 25.433 published by 3GPP,
- for common channels, during the procedures of establishment, elimination, or reconfiguration, of a common channel (or in English “common transport channel set-up”, “common transport channel deletion”, “common transport channel reconfiguration”) such as those defined in the document 3G TS 25,433 published by the 3GPP.
Such procedures are also called NBAP ("Node B Application Part") procedures, and the corresponding signaling messages are also called NBAP messages.
In the 3G TS 25.433 standard, two different consumption laws have been defined, one for dedicated channels, and one for common channels. Remember that a dedicated channel is a channel assigned to a given user, while a common channel is a channel shared between several users. For example, in UMTS system, the DCH channel (for “Dedicated CHannel”) is a dedicated channel, and channels such as, especially, RACH (for “Random Access CHannel”), FACH (for “Forward Access CHannel ”), CPCH (for“ Common Packet Channel ”), DSCH (for“ Downlink Shared CHannel ”), ... etc, are common channels.
As the applicant has observed, the credit mechanism such as that described in the 3G TS 25,433 standard in its current state still raises certain problems.
A first problem is that the particularities of the DSCH channel are not taken into account.
Although the DSCH channel is actually a common channel, it is always associated with a dedicated DCH channel and the establishment, elimination or reconfiguration procedures that concern the DSCH channel concern
ES 2 302 786 T3 simultaneously to the DCH channel. For example, for a "radio link set-up" operation, one or two operations can be carried out: one for the DCH channel and, possibly, one for the DSCH channel, if a DSCH channel is associated with the DCH channel.
Thus, even if the DSCH channel is a common channel, it would be more logical (in order to simplify the capacity credit update operations), that this channel was taken into account in the consumer law for dedicated channels.
But, for dedicated channels, the allocation cost is different depending on whether or not the radio link considered is a first radio link (the second case corresponding to the situation in which the UE has more than one radio link in the same Node B. , that is, in which the UE is in a situation called, in English, of "softer-handover" with this Node B). Thus, the 3G TS 25.433 standard specifies that for a first radio link, two costs are taken into account, namely, a cost for a radio link (or "Radio Link cost", or also "RL cost") and a cost for a set of radio links (or “Radio Link Set cost” or also “RLS cost”), while for an additional radio link, only the cost “RL cost” is taken into account.
However, for common channels and, in particular, for the DSCH channel, the “soft handover” or “softer handover” technique is not generally used. Thus, the DSCH channel poses particular problems for the application of this credit mechanism, which must be solved.
One of the objects of the present invention is to provide a solution to these problems.
Thus, one of the objects of the present invention is a method for managing treatment resources in a mobile radiocommunication system, in which the base station controller manages radio resources and corresponding treatment resources, the latter being provided in a base station, procedure in which:
- the base station signals to the base station controller its global processing capacity, or capacity credit, and the consumption law, or amount of this global processing capacity, or cost, depending on the necessary radio resources,
- the base station controller updates the capacity credit based on the consumption law,
- for the case of radio resources corresponding to dedicated channels, a different allocation cost is provided for the case of the first radio link, and for the case of an additional radio link, a procedure characterized in that:
- for the case of radio resources corresponding to a common channel associated with a dedicated channel, said update is carried out, in the case of the first radio link, based on the cost for the dedicated channel and a cost for the associated common channel , and in the case of additional radio link, only on the basis of the cost for the dedicated channel.
According to another feature,
- for the case of a dedicated channel, the cost for a first radio link includes a cost for a radio link and an additional cost, and the cost for an additional radio link includes only the cost for a radio link.
- for the case of a common channel associated with a dedicated channel, the aforementioned cost for the associated common channel corresponds to the cost of a radio link for the dedicated channel.
According to another characteristic, said cost for the associated common channel is specific to this channel.
According to another characteristic, said common channel associated with a dedicated channel is a channel of the DSCH type ("Downlink Shared CHannel").
According to another characteristic, the cost is a function of the spreading factor.
Another object of the present invention is a mobile radio communication system, in which:
- a base station (Node B) comprises means for signaling to a base station controller its global processing capacity, or capacity credit, and the amount of this global processing capacity, or cost, as a function of radio resources necessary,
- a base station controller (RNC) comprises means to update the capacity credit on the basis of the consumer law,
ES 2 302 786 T3 characterized in that:
- the base station controller comprises means for, in the case of radio resources corresponding to a common channel associated with a dedicated channel, updating the capacity credit, in the case of the first radio link, based on the cost for the channel dedicated and of a cost for the associated common channel, and in the case of additional radio link, only on the basis of the cost for the dedicated channel.
Another object of the present invention is a base station controller
- comprising means for receiving from a base station (Node B) its global processing capacity, or capacity credit, and the amount of this global processing capacity, or cost, depending on the necessary radio resources,
- characterized in that it comprises means for, in the case of radio resources corresponding to a common channel associated with a dedicated channel, updating the capacity credit, in the case of the first radio link, based on the cost for the dedicated channel and a cost for the associated common channel, and in the case of additional radio link, only on the basis of the cost for the dedicated channel.
Other objects and characteristics of the present invention will become apparent upon reading the following description of exemplary embodiments, made in relation to the attached drawings, in which:
- Figure 1, described above, recalls the general architecture of a mobile radiocommunication system, such as, especially, the UMTS system,
Figures 2 and 3, described above, recall the main treatments used, respectively, in transmission and reception, in a base station, such as a Node B, for the UMTS system,
FIG. 4 is a diagram intended to illustrate an example of putting into practice a method according to the invention.
Thus, the present invention is especially aimed at solving the problem posed by the credit mechanism such as that described in the 3G TS 25,433 standard in its current state.
The problem is that the particularities of the DSCH channel are not taken into account.
The solution to solve this problem according to the invention can also be explained as follows.
Since the DSCH channel is always associated with a DCH channel, it may be preferable to take into account its treatment cost in the consumption law of the dedicated channels.
Several solutions can be adopted:
- A specific cost is added to the consumption law for the DSCH channel, for some values of spreading factors or for all possible values of spreading factors (the second solution being preferable, that is, a cost per spreading factor, as is the case for the DCH channel).
- one of the costs specified for DL DCH (or “Downlink DCH”, or DCH in the downstream direction) is taken into account, that is, “DL RL cost” (it will be noted that only one cost is taken into account for the downstream direction since the DSCH is a downstream channel only and since usually the treatment presents significant differences for the emitter and the receiver of Node B).
Since the soft-handover cannot be used for the DSCH channel, no additional resources are used for the DSCH channel when a new radio link is added. The preferred solution is therefore to add / change / remove a cost for the DSCH channel only once, when the NBAP messages concern a first radio link.
More precisely:
- during a radio link establishment procedure (or in English “Radio Link Set-up”), the DSCH cost (that is, the specific cost, that is, the “DL RL cost” for the DCH, according to the two possibilities indicated above) is debited from the capacity credit (this cost is debited only once, regardless of the number of radio links, as opposed to the DCH cost),
- during a procedure for adding a radio link (or in English “Radio Link Addition”), the capacity credit is not modified because of the DSCH (but it can be changed to take into account the DCH treatment),
ES 2 302 786 T3
- during a radio link reconfiguration procedure (or in English “Radio Link Re-configuration”), the capacity credit is modified because of the DSCH channel only once (if the new DSCH cost is different from the old one) whichever be the number of radio links.
Thus, in general, to solve this problem, the invention essentially provides that, for a common channel associated with a dedicated channel, said update is carried out, in the case of the first radio link, on the basis of the cost for the dedicated channel and a cost for the associated common channel, and in the case of additional radio link, only on the basis of the cost for the dedicated channel.
According to an advantageous embodiment, when a PDSCH channel ("Physical Downlink Shared CHannel") is assigned in the "Radio Link Set-up" procedure, the treatment cost associated with this PDSCH channel, equal to "DL RL cost ”, is debited from the capacity credit, in addition to the cost of treating the radio links. Similarly, the capacity credit is credited at this cost when a PDSCH channel is eliminated, and the difference between the new cost and the old cost is debited from the capacity credit (or credited if this difference is negative) when a PDSCH channel it is reconfigured.
Figure 4 is a diagram intended to illustrate an example of means to be provided in a base station (or Node B in a system such as the UMTS system), and in a base station controller (or RNC for a system such as the UMTS system), to implement such a method according to the invention.
Thus, a single base station indicated by Node B comprises (in addition to other means that can be classic means):
- means indicated by 13 for signaling to a base station controller its global processing capacity, or capacity credit, and the amount of this global processing capacity, or cost, as a function of the necessary resources.
Thus, a base station controller indicated by CRNC (from "Controlling Radio Network Controller") comprises (in addition to other means that may be classical means):
- means indicated by 14 to receive from a base station its global processing capacity, or capacity credit, and the amount of this global processing capacity or cost, depending on the necessary resources,
- means indicated by 15 to update the capacity credit on the basis of the consumer law, the said update being carried out, in the case of the first radio link, on the basis of the cost for the dedicated channel and a cost for the common channel associated, and in the case of additional radio link, only on the basis of the cost for the dedicated channel.
These different means can operate according to the procedure described above; Their realization not presenting particular difficulty for the person skilled in the art, such means only need to be described here in more detail because of their function.
In the above description, the cost may be a function of the spreading factor, as specified in the previously recalled standard (in its current state). However, the principle thus described is not limited to this case, and applies equally to the case in which the cost is a function of one or several other parameters, such as, in particular, the flow rate, in accordance, moreover, with other known solutions.
It will be observed that the term "update" of the capacity credit used in all the foregoing is intended to cover both the operations for which this capacity credit is owed, in the case that new radio resources are required, as well as the operations for which this capacity credit is paid, in the event that new radio resources are not necessary and, therefore, are restored.
Especially:
- for the “radio link set-up”, “radio link addition” and “common transport channel set-up” procedures, the capacity credit is owed,
- for the “radio link deletion” and “common transport channel deletion” procedures, the capacity credit is paid,
- In the case of "radio link reconfiguration" and "common transport channel reconfiguration" the capacity credit is owed or paid depending on whether the difference between the allocation cost for the new throughput and for the old throughput is negative or positive.
ES 2 302 786 T3
In the above description, the cost may be a function of the spreading factor, as specified in the previously recalled standard (in its current state). However, the principle thus described is not limited to this case, and applies equally to the case in which the cost is a function of one or several other parameters, such as, in particular, the flow rate, in accordance, moreover, with other known solutions.
