Method of allocating access rights to a telecommunications channel to subscriber stations of a telecommunications network and subscriber station
A method and a subscriber station for allocating rights of access to a telecommunications channel of the telecommunications network to at least one subscriber station (5, 10, 15, 20) are proposed in which information signals are transmitted to the at least one subscriber station (5, 10, 15, 20). With the information signals, access authorization data (45, 50, 55) are transmitted to the at least one subscriber station (5, 10, 15, 20). Upon reception of the access authorization data (45, 50, 55) in an evaluation unit (6) of the at least one subscriber station (5, 10, 15, 20), the question is asked whether the access authorization data (45, 50, 55) include an access threshold value (S), and the access threshold value (S) is compared with a random number or a pseudo-random number (R), and the right of access to a telecommunications channel of the at least one subscriber station (5, 10, 15, 20) is granted as a function of the outcome of comparison.

The invention is based on a method of controlling or administering access to a telecommunications channel for a subscriber station.
From German Patent Application Serial No. 19838832.2, not yet published by the priority date of the present application, a method for controlling access to a telecommunications channel of a telecommunications network for at least one subscriber station of the telecommunications network is known in which information signals are transmitted to the at least one subscriber station.
SUMMARY OF THE INVENTIONThe method of the invention and the subscriber station of the invention have the advantage over the prior art that with the information signals, access authorization data are transmitted to the at least one subscriber station; that upon reception of the access authorization data in an evaluation unit of the at least one subscriber station, the question is asked whether the access authorization data include an access threshold value, and the access threshold value is compared with a random number or a pseudo-random number; and that the right of access to a telecommunications channel of the at least one subscriber station is granted as a function on the outcome of comparison, preferably on the condition that the random number or the pseudo-random number is greater than or equal to the access threshold value. In this way, a random distribution of the access authorization to this telecommunications channel for one or more subscriber stations can be achieved. This access control takes up a minimum of transmission capacity for transmitting the information signals, since it is effected merely by transmitting the access threshold value.
By the provisions recited in the dependent claims, advantageous refinements of and improvements to the method defined by independent claim 1 are possible.
It is especially advantageous that in the evaluation unit of the at least one subscriber station, the question is asked whether the access authorization data include access authorization information with access class information for at least one predetermined user class, in which case, and on the condition that the at least one subscriber station is assigned to the at least one predetermined user class, to which access to a telecommunications channel of the at least one subscriber station is granted as a function of the access class information for this user class. In this way, subscriber stations of a predetermined user class are allowed to use the telecommunications channel even whenever, on the basis of the random distribution by means of the access threshold value are not authorized access to this telecommunications channel. For instance, subscriber stations of emergency services, such as the police or fire department are assigned to a predetermined user class of this kind and can then access the telecommunications channel with priority by means of appropriate access threshold value ink, independently of the random distribution.
A further advantage is that in the evaluation unit of the at least one subscriber station, the question is asked whether the access authorization data include priority information in the form of priority threshold value, in which case and on the condition that the at least one subscriber station is assigned to a pk with a priority value, the priority value is compared with the priority threshold value, and the access to a telecommunications channel of the at least one subscriber station is granted as a function of the outcome of the comparison, preferably on the condition that the priority value is greater than or equal to the priority threshold value. In this way, among the subscriber stations randomly authorized to access this telecommunications channel, a further selection is additionally made, which prefers subscriber stations of higher priority for the access to this telecommunications channel. In this way again, subscriber stations of emergency services such as the police or fire department are given priority, although as a function of the random distribution by means of the access threshold value.
A further advantage is that in the evaluation unit of the at least one subscriber station, the question is asked whether the access authorization data include telecommunications service information, which for telecommunications services offered by the telecommunications network indicate whether the access to at least one telecommunications channel for requesting such a telecommunications service is enabled. For each of the user classes authorized access by the above-cited criteria, it is additionally defined which telecommunications services can be requested via the telecommunications channel. In this way, once again transmission capacity for transmitting the information signals is saved, since different telecommunications services need not be requested by various user classes—in accordance with the above criteria—that are authorized access; instead, for each of these preselected subscriber stations, only the specified telecommunications services can be requested via this telecommunications channel. Thus only minimal service information has to be transmitted along with the information signals.
Another advantage is that in the evaluation unit of the at least one subscriber station, the question is asked whether the access authorization data include an item of access information which indicates whether the access authorization data include either an access threshold value or access channel information, and that the access authorization data are evaluated in accordance with the answer to the question in the at least one subscriber station. In this way, the requisite transmission capacity for transmitting the information signals can be reduced still further, because the access authorization ink include either only the access threshold value or only the access channel information, but not both together.
Still another advantage is that the access to this telecommunications channel of the at least one subscriber station is enabled as a function of the incidence of message traffic on at least one telecommunications channel. In this way, an optimal distribution of the telecommunications channel resources to the subscriber stations can be attained, with the best possible utilization of the transmission capacity.
Exemplary embodiments of the invention are shown in the drawing and explained in further detail in the ensuing description.
In
A network operator of the mobile radio network offers a predetermined number of telecommunications services. As examples hereinafter, three different telecommunications services are to be offered by the network operator. As a first telecommunications service, for instance, a service for sending small data packets can be provided, which can be employed by the mobile stations 5, 10, 15, 20 to transmit small data packets to the base station 100 via a nonselective access class 30, which is assumed hereinafter to be embodied as a RACH (random access channel), for example. As a second telecommunications service, a service for sending larger packet data can be provided, in which the RACH 30 can be used by the mobile stations 5, 10, 15, 20 to request separate data channels for packet data transmission. As a third telecommunications service, a service for speech or landline data transmission may for instance be provided, in which the RACH 30 can be used by the mobile stations 5, 10, 15, 20 to initiate or continue speech and/or data transmissions.
The three telecommunications services can be permitted individually and/or in arbitrary combination to the mobile stations 5, 10, 15, 20 by the network operator.
The telecommunications services must be requested from the network operator by the applicable mobile station via the base station 100. The telecommunications services are typically requested by the mobile stations 5, 10, 15, 20 or made accessible via the RACH 30. Via the RACH 30, messages can as a rule be sent from a plurality of mobile stations to the base station 100. Hence messages from various mobile stations can collide with one another. The base station 100 therefore confirms messages that have been properly received, by sending appropriate confirmation or acknowledgment ink over another channel, not shown in
For the case where the message from one mobile station on the RACH 30 collides with another message, proper reception of this message does not take place in the base station 100, so that the base station 100 cannot send any confirmation ink back to the applicable mobile station, either. After a predetermined time in which no confirmation ink was received from the base station 100, the mobile station therefore usually re-sends the message to the base station 100 via the r30. This runs the risk of overloading the r30, which thus limits the user-initiated requesting of telecommunications services by the application mobile stations because of its limited transmission capacity.
An overload on the r30 can be avoided by having the network operator restrict access to the RACH in a targeted way for the individual mobile stations 5, 10, 15, 20. The access to the RACH may for instance be permitted only for certain user classes of mobile stations either temporarily or with permanent priority. In the exemplary embodiments described in conjunction with
By means of information signals, which are transmitted from the base station 100 to the applicable mobile station 5, 10, 15, 20, the network operator informs the various mobile stations 5, 10, 15, 20 which rights for transmitting on the RACH are granted to the applicable mobile station 5, 10, 15, 20. This will be described below in terms of the granting of rights to transmission on the RACH to the first mobile station 5 of
At predetermined times, the base station 100 transmits information signals to the first mobile station 5. The information signals can be transmitted, as shown in
Among the possible purposes for access are for instance the cases already described above, such as sending small data packets, requesting a channel for larger packet data, and requesting a channel for speech/data services.
Another possible purpose for access, however, is sending signaling information from the subscriber station to the base station, ink which serves to maintain and/or modify already existing connections.
Since the bit pattern sent from the base station is sent not only to the first mobile station 5 but also to all the other mobile stations 10, 15, 20, and likewise over the signaling channel 25, which as described is embodied as a BCCH, that is, a point-to-multiple-point channel, so that all the mobile stations receive the same ink at the same time, the bit pattern includes the access rights granted to each user class 35, 40, for the sake of informing the mobile stations of the RACH access rights they have been allowed.
A random distribution of the access authorization on the r30 over some of the mobile stations 5, 10, 15, 20 is attained in that an access threshold value S is sent over the BCCH. In
A first exemplary embodiment will now be described in conjunction with
The bits 5, 10, 15, 20 can additionally be assigned to so-called priority channels 80, 85. In
It can also be provided that a predetermined priority value that corresponds to one of the four possible priority values is stored in a memory of the evaluation unit. If the evaluation unit 60 does not detect any priority value on the access authorization card 75, it can use the predetermined priority value for comparison with the priority threshold value P as described.
In
In
If an access class bit of the second bit pattern 50 is set to 1, then no mobile station of the associated user class can access the r30.
All the mobile stations that are allowed to access the r30 can use those telecommunications services whose associated telecommunications service bits in the first bit pattern 45 or the second bit pattern 50 are set.
It can also be provided that a predetermined priority value, which corresponds to one of the four possible priority values, is stored in a memory of the evaluation unit. If the evaluation unit 60 finds no priority value on the access authorization card 75, then it can use the predetermined priority value for comparison with the priority threshold value P, as described.
The membership in a user class is also detected by the evaluation unit of the corresponding mobile station from the access authorization card 75. If no user class is stored in memory on the car, then the evaluation unit of the corresponding mobile station recognizes that this mobile station does not belong to any user class.
If the evaluation bit S4 is set to 1, no access to the r30 is possible for mobile stations that do not belong to any user class.
Below an example will be described for a bit pattern whose bit length is 10 bits and which is transmitted along with the information signal. In this example, the bit sequence “to 0 1000 011 01” is sent to the mobile stations 5, 10, 15, 20 by the base station 100 via the BCCH 25. This means that the mobile stations that are assigned to a user class will be treated like mobile stations that are not assigned to any user class, since the evaluation bit S4 is not set. The access threshold value S is encoded in binary form by means of the access threshold value bits S3, S2, S1, S0, and the priority threshold value P is encoded in binary form by the priority bits P1, P0. For the access threshold value S, a value of 8 thus results, and for the priority threshold value P, a value of 1. If after P and S have been evaluated a mobile station is authorized access, then it is still allowed use of the RACH solely for channel requests for larger packet data services and for speech/data services. Because of the above setting for the service ink, such mobile stations are NOT permitted to use the RACH for sending small data packets.
The second, third, fourth and fifth bits of the first bit pattern 45 and second bit pattern 50 represent access authorization ink, which in the first bit pattern 45 indicates the access threshold value S and in the second bit pattern 50 indicates the authorization of access for the four user classes. The first bit determines whether the second through fifth bits will be interpreted in accordance with the first bit pattern 45 or the second bit pattern 50.
In a second exemplary embodiment, in
In comparison to the first bit pattern and the second bit pattern, in the third bit pattern the access authorization ink includes both the access threshold value bits S3, S2, S1, S0 and the access channel bits Z3, Z2, Z1, Z0.
The numbers of bits used for the access threshold value S, the access channel ink Z0, Z1, Z2, Z3, the priority threshold value P and the telecommunications service ink D0, D1, D2 are understood to be merely examples, and they can also be increased, for example for more-extensive signaling, and reduced, for the sake of bandwidth reduction. In this case, the total length of the bit patterns 45, 50, 55 may change as well. Individual components of the ink can optionally also be omitted entirely.
In all cases where the program is not exited from program point 250, the evaluation unit 50 will have found no allowed access to the r30 for the associated mobile station 5. After the end of the program, the mobile station informs the user that the access to the r30 was not possible, and waits for further inputs from the user. Alternatively, by means of a waiting loop embodied in the mobile station, the program is executed over again, so there is a wait for the next information signal with the next bit pattern, and the information signal is then evaluated to ascertain the ab to the r30.
The information signals are transmitted from the base station 100 to the mobile station 5, 10, 15, 20 are predetermined times, preferably at regular intervals. The network operator can, by the method described, either permit or block access to the RACH as a function of the incidence of message traffic in the telecommunications network and thus as a function of an expected utilization of the r30 for the individual mobile stations 5, 10, 15, 20. Since the incidence of message traffic in the telecommunications network varies over time, the expected utilization of the r30 also varies over time, so that by means of the correspondingly changed bit pattern allocation, access to the RACH is as a rule allocated to the various mobile stations 5, 10, 15, 20 at different times.
A relief of the r30 can additionally be attained by providing a repetition counter and/or a repeat interval. The repetition attempts allowed for re-sending a message from the corresponding mobile station to the base station 100 over the r30, in the event of collision with a message from another mobile station. The repeat interval is a stochastic measure of the time interval until the next repetition of the message sent over the r30 from the applicable mobile station to the base station 100. The lower the number of repeat attempts allowed, and the greater the repeat interval, the greater the relief of the r30. Together with the bit pattern of the access rights granted, the repetition counter and/or the repeat interval can be imparted to the applicable mobile stations at regular time intervals over the associated signaling channel 25, optionally along with other radio-cell-specific ink. The method of the invention can be achieved in a mobile radio network by the UMTS (Universal Mobile Telecommunication System) standard, the GSM standard, or the like.
The method of the invention is not limited to use in a mobile radio network, but instead can be employed generally in telecommunications networks in which there is a telecommunications channel that is used by a plurality of subscriber stations to request telecommunications services and/or to send data packets; the telecommunications network can for instance also be a fixed landline network.
In another version, it can also be provided that for an authorization of access, the prerequisite is a random or pseudo-random number R less than the access threshold value S. Correspondingly, for the priority checking by means of the priority threshold value P, it can be a prerequisite that the random or pseudo-random number R is less than the priority threshold value P.

- an evaluation unit for asking when information signals with access authorization data comprising access class information for at least one prescribed privileged user class and access threshold value bits conveying an access threshold value are received, whether the access authorization data include an access threshold value for comparison of the access threshold value with a random number or a pseudo-random number, and whether an access authorization card associated with the subscriber station holds an affiliation of the subscriber station to a privileged user class and if so whether initial access to the random access channel is granted to the subscriber station by the access class information for this privileged user class irrespective of the access threshold value, and having determined that the subscriber station is either not associated with a privileged user class or is associated with a privileged user class for which initial access to the random access channel is not granted on the basis of the access class information irrespective of the access threshold value, for comparing the access threshold value with a random number or a pseudo-random number, and for ascertaining, as a function of an outcome of the comparison whether initial access of the subscriber station to the random access channel is enabled.
23. The subscriber station of claim 22, wherein the evaluation unit is further arranged to ascertain, as a function of the comparison whether the initial access of the subscriber station to the random access channel is enabled, if the subscriber station is associated with a privileged user class and initial access to the random access channel is not granted to the subscriber station on the basis of the access class information.
