The present invention relates to a method of band selection system for broadband wireless access (shbd), and more specifically to a method of band selection for a mobile communication system using multiple access orthogonal frequency division (MDRC).

Typically, the schema MDRC defined as a scheme with two-dimensional access to Association schemes of access with time division (RTD) - schema of the access frequency division (HDR). In the case of transmission using the scheme MDRC, symbols MDRC separately loaded onto subcarriers and transmit on a prescribed subchannels. The communication system using the scheme MDRC should periodically perform a process of selecting a range in order to properly set the time offset between the transmitting side, that is, node B and the receiving side, that is, a user equipment (ON), and to regulate the power between them.

Selection range is classified according to the process of the source range selection, the selection process of the query range bandwidth and range selection support (periodic range) in accordance with their tasks.

Code range (KM) for the process of range of support corresponds to a periodic code, periodically transmitted in Uzes is B through. The process of range of support is also referred to as periodic ranging.

The tasks of the aforementioned three processes range were defined in the IEEE (international electrotechnical Commission) number 802.16.

Procedure range requires a range of subchannels and KM, and is assigned with different KM according to these three objectives. However, the standard document prescribed in IEEE 802.16, does not specify how a resolution to appoint KM multiple processes range with various applications and message.

IEEE 802.16 defines the prescribed scheme in which a node B transmits a message Kartals (map uplink connection (VLAN), (UL_MAP)) for information about the reference information in the access uplink communication. Message Kartals informs about different information in uplink communication, for example, about the period of planning and configuration of the physical channel, and so on. Accepts the message Kartals and performs the procedure associated with range selection, on the basis of information contained in the message Kartals, is transmitted in all cells through the data broadcast node B.

As shown in table 1, the message Kartals has the following configuration.

As shown in table 1, region Elementinformation, which serves as the field IE (information element), messages Kartals, includes the area ID (ID), the connection region of KEULS (code use interval ascending line) and the field offset. In the ID field of the connection record information indicating the transmission scheme in it. Transmission scheme is classified according to the scheme of unidirectional transmission, the scheme of the broadcast and the scheme shirokanedai is. In the field of CHILLS record information showing the use of offsets recorded in the area of displacement. For example, the number 2 is written in the field of KEULS means that the offset of the beginning for use in the initial selection process of the range recorded in the area of displacement, number 3, recorded in KEULS means that the offset of the beginning for use in the selection process of the query range bandwidth or range of support recorded in the area of displacement. In the field of offset is the value entry initial offset for use in the process of source selection range, or are in the process of range of support, according to the information recorded in the field of CHILLS.

Known configuration messages Kartals shown in table 1, classified according to the three processes range, according to the aforementioned tasks, but it does not provide allocation KM, by which an independent process for each of the three processes range becomes available. In other words, although known configuration messages Kartals causes range mode by using the segmentation PSH (pseudotumor), as well as develops KM available for these three tasks, can not recognize this kind of information, that is, the range mode and KM. So DL is known messages Kartals you must perform the allocation KM for processes to be performed independently of the range, with a variety of tasks.

Usually even the communication system MDRC allows you to perform all the conditions near or away from the line of sight in the same manner as in the environment channel of a mobile communication system using different modulation schemes and access, and contains a partial blocking of the signal that caused the forest, which can affect the signal attenuation and multipath signal propagation. Therefore, it may occur simultaneous transmission of signals at the initial stage of transmission, regardless of the type of selection process the range used ON the site, and then a random seed number to provide the same value of delay, as in the period of initial access adapts during the period of time re access.

Known to the node B transmits the message GQVLS (handle, channel uplink communication) with the information showing the value of delay in such a way that identified the value of deferral. This message GQVLS presented in table 2.

As shown in table 2, the node B transmits the message GQVLS with the information showing the value of delay available during the time period of the access granted after the expiry of the period of refusal of access. In other words, the value of postponing shows the kind of time-out response to the request, is AutoRAE represents the period of time between the start time of the denial of access and early access later ON. The node B transmits in the value of delay showing information about time-out response to the request, during which ON should expect the following process range after refusing to carry out an initial selection process range. For example, for the number 10, as defined using the above syntax the "start delay range" and "the end of the delay range, which are shown in table 2, must pass 210-one running the likely event of access (i.e., 1024-one running the likely event access) and then perform the following process range in accordance with the algorithm truncated binary exponential delay. On closer examination, receives a message Kartals, and its access time range corresponds 1025-th period of access, the operation range can be performed on 1025-th period of access. However, as stated above, KM differently assigned according to the three processes range and, in addition, the dynamic method is assigned according to the status of the cell, so that the delay value sent with the message GQVLS, necessarily assigned differently according to the task KM.

In conclusion, the communication system using the scheme MDRC, classifies its procedure of choosing the range is and on three types of processes range in accordance with their task. Although km away, and a different way to assign three processes range, cannot identify the information showing the type of the process range and, thus, cannot perform an operation independent of range. Known communication system that uses the schema MDRC cannot perform dynamic allocation, which is variable according to the status of the cell and the characteristics of access to the software, because the software cannot identify such information about the type of range, thus increasing the number of times of access to the range selection procedures selection range. As a result, the known communication system that uses the schema MDRC has a flaw, which is that it inevitably increases the length of time access delays and reduces overall system performance.

Therefore, the present invention provides the above problems, and an object of the present invention is to perform a method of dynamically assigning different KM for the software in accordance with the objectives of the selection range in the communication system using the scheme MDRC.

The above and other objectives, features and other new EMP shall define the company present invention will be clearer from the following detailed description in conjunction with the accompanying drawings, on which:

figure 3 depicts a diagram illustrating the assignment procedure code range and values of delay for the software in accordance with objective selection range, according to a preferred variant implementation of the present invention.

Below is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings. In the drawings, identical or similar elements are denoted by the same position even when the image on different drawings. The following description is omitted a detailed description of known functions and configurations incorporated herein, when it may obscure the subject matter of the present invention.

Figure 1 shows a diagram depicting the procedure for allocation KM (code range) for the ICI is neither based communication schemes MDRC in accordance with the preferred embodiment of the present invention.

As shown in figure 1, KM is formed by segmentation PSH (pseudotumour) code having a prescribed length, for example, length 215-1 bits in the prescribed units. Typically, one channel range consists of two subchannels range, each of which has a length of 53 bits. KM is formed by using such a segmentation code PSH channel range of 106 bits. A maximum of 48 KM (KM (code range)#1~KM#48) can be assigned to (user equipment). More than two MILES for each used as the value assigned by default to the three processes range with different tasks, that is, the process of source range selection, the selection process of the query range bandwidth and range (=periodic range) support. These processes range and their functions are the same as in the aforementioned prior art. In particular, the KM for use in the process of range of support corresponds to a periodic code, periodically transmitted to the node B, and thus the process of range of support is also referred to as periodic ranging. Therefore, KM is assigned a different way in accordance with each task of the three processes range. Then e is th as shown in figure 1, N KM appoint to process the source range, which is denoted by a prescribed member of the "N KM source range" in figure 1, M KM appoint for the process of range of support, which is denoted by a prescribed member "M KM for range selection support", and L KM appoint to the selection process of the query range bandwidth, which is denoted by a prescribed member of the "L KM for range selection query bandwidth". KM for the process of range of support represents a prescribed code, periodically transmitted from the node B, so it is also called periodic code.

The standard prescribed by the IEEE (international electrotechnical Commission) 802.16 standard currently specifies the maximum number of MILES that can be allocated, and the prescribed default, highlighted, but it does not describe the detailed method of appointment of such KM. Therefore, unable to identify the reception of information about KM and, consequently, to perform adaptive operation in the case of simultaneous transmission of signals between the transmission KM or other procedures that relate to the selection range. In order to solve these problems, in the present invention, a method for allocating KM, as well as a way to reduce time sagarikaghose to by assigning independent values of delay for each KM, and in the future, given their detailed description.

More specifically, the present invention classifies KM according to the above three objectives, and informs about the range of KM, are available at the moment for that leads to the minimum delay time of access. In this case, a message indicating such classification and the range of KM is the message UL(upward line)_MAP, and this message Kartals has the following configuration, which is shown in table 3.

As shown in table 3, one appointed BY 48 KM as the maximum number of MILES. Provided that at least two MILES from among 48 KM assigned as a specific KM for each of the three tasks range, assign only 6 km AWAY. Such KM assign a different way for each task range, one appointed BY more than two KM, corresponding to each KM for the three tasks range, and the maximum number of 48 KM is available for one ON. In other words, the message Kartals shown in table 3, contains the original KM to process the source range, and periodic KM, such as KM of the request bandwidth and KM support that is passed in. Therefore, BY receiving Kartals allows you to use right AWAY in response to his own problem of the current selection range. In addition, the node B dynamically assigns KM for the software in accordance with the current status of the cell. For example, if several are connected (hereinafter referred to as ON in SOS is the right connection) within a cell, the node B may assign a lot of MILES (that is, the initial KM) for use during initial range for during initialization. Provided that a large number in the connection state is contained in a cell, the node B may reduce the number of MILES assigned to the original KM. In short, the node B dynamically assigns KM each according to the overload condition within a cell. This dynamic allocation KM can be adapted to control the pressure cell and the priority cell. Allocation KM varies with the status of the cell, which reduces the delay time of access.

Message GQVLS (handle channel uplink communication) for various settings of the delay values according to the type of KM will be further described with reference to table 4.

As shown in table 4, the message GQVLS issues FOR different values of delay in response to the number of MILES that are dynamically assigned according to the number ON the status of the connection within a cell, and those that attempt to perform initial dostupno is, if KM, with different tasks, assign different values of the delay, access to the site, which is located in a cell, is controlled in accordance with the status of the cell. Thus, the access control by assigning different values of the s grace, that results in the minimum delay time of access. For example, in the case where 10 KM appointed through a process of initial selection of range message Kartals and the remaining KM, which differ from the 10 KM, appointed through a process of selection of the query range bandwidth and selection process of the support band, the probability of conflict code caused BY correspondingly choosing the same MILES as their original MILES, equal to 1/10. Therefore, in order to further reduce the likelihood of such conflicts BY choosing the same KM, if the time of readmission within which each perform a second access to the KM process in the initial range is divided into many segments of the access time, that is, if each assign a high value of the delay of the source range, then the probability of conflicts among in the process of source selection range can be greatly reduced. Even in the case where the selection process of the query range bandwidth, which typically assigns a lot more MILES than the original range, assigns a relatively low delay, which is lower than the original value of the delay range, the likelihood of conflict in the selection process of the requested range is and bandwidth can also be reduced because the number of MILES designated in the selection process of the query range bandwidth much greater than the number of other KM assigned to process the source range. Thus, the access time to each is reduced by reducing the value of delay, which is used in the selection process of the query range bandwidth.

The node B to perform allocation KM and highlight the value of delay according to the task range will be described below with reference to figure 2.

Figure 2 shows an algorithm illustrating a procedure for assigning KM and the value of delay for each process select the range according to the task range of node B, according to a preferred variant implementation of the present invention.

As shown in figure 2, node B checks its own status cell at step 210. In more detail, the node B checks the overload condition of its own cell based on the number that are in the current moment of time in a state of traffic on the stage 210. The node B generates KM at step 212. In more detail, as shown above in figure 1, node B generates many MILES through segmentation PN code having a length of 215-1 bits in predefined blocks at step 212. The node B assigns KM, which will be used for the three selection processes range is, with different objectives, i.e. to process the source range selection, the selection process of the query range bandwidth and selection process of range of support according to three processes range at step 214. In more detail, as shown above in figure 1, the node B assigns a number N KM process in the initial range, assigns a number L KM to the selection process of the query range bandwidth and assigns the number M KM the selection process of the support band on stage 214. In case of the appointment KM each process range at step 214, the node B changes the number of MILES that you want to use to process the source range selection, the selection process of the query range bandwidth and selection process of range of support in accordance with the status of a cell, which is checked at step 210. In the case where at step 216 determines that the cell is in a state of extreme loads in excess of the prescribed condition of overload, the node B proceeds to step 218.

The node B controls the number of L KM to the selection process of the query range bandwidth to exceed the number N KM to process the source range, and performs the allocation KM to the selection process of the query range bandwidth at step 218, since the cell is in this state, strong in the power stage 216, and moves to step 220. That is, the node B performs the allocation KM to the selection process of the query range bandwidth when the prescribed condition L>N at step 218. The reason why the node B performs such prescribed condition L>N at step 218, is to minimize the number of conflicts caused by the operation of the source range, as previously installed. In more detail, provided that any cell is in a state of high overload, this means that the cell has too much traffic. Therefore, in case of the appointment KM each process range, the node B controls the number of L KM, which will be used to process a range selection query bandwidth to exceed the number N KM, which will be used to process the source range, thus minimizing the number of conflicts uplink communication at step 218. The node B performs the allocation of the value of the delay for the selection process of the query range bandwidth at step 220. In this case, provided that the value of the delay for the source code of the range indicated by the letter 'A', the value of delay for the code range selection query bandwidth indicated by the letter 'B' and the value of delay for code range selection support indicated what uquoi 'C', the node B controls the value of grace, which is less than the value of the delay at step 220, that is, performs a prescribed condition B<And at step 220, and then proceeds to step 222. The value of deferral reduces the duration of the period of time re access caused by conflicts among several, is inversely proportional to the value of the delay, in contrast to the number of KM, thus minimizing the delay time caused by the conflict of access to the uplink connection. That is, the lower value of the delay is shorter than the time to re-access.

The node B controls the number M KM (hereinafter referred to as the AWAY support) for the process of range of support to exceed the number N KM (hereinafter referred to as the source KM) to process the source range, and performs the allocation KM to the selection process of the support band on stage 222, and then proceeds to step 224. The node B controls the value of C delay, which is equal to the value of the delay range of support, so that it is less than the value of the delay that is equal to the initial value of the delay range at step 224, that is, performs the selection of the values of the delay to process the source range in the prescribed condition C at step 224, and then proceeds to step 226. The node B controls the number N of the original KM, which Dol is but to be less than the number of L KM to request bandwidth or the number m of KM support, and performs the allocation of the original KM on stage 226, and then proceeds to step 228. The node B controls the value And postponement of the original range to exceed the value of B delay range selection query bandwidth or the value of the delay range support at stage 228, that is, performs a prescribed condition A>B or C at step 228, and then proceeds to step 242.

Meanwhile, in a case where at step 216 determines that the cell is not in a state of extreme loads in excess of the prescribed condition of overload, the node B proceeds to step 230. Steps 230-240 perform contrary to the foregoing steps 218-228. In more detail, the node B controls the number of L KM of the request bandwidth so that it is less than the number N of the original KM, and performs the allocation KM to the selection process of the query range bandwidth at step 230, as honeycomb is in a state of relatively low overload at step 216, and moves to step 232. The node B controls the value of B delay range selection query bandwidth to exceed the original value And the delay range at step 232, that is, performs a prescribed condition B>A at step 232, and then proceeds to step 234. The node B controls the number M KM podderjite, so it was less than the number N of the original KM on stage 234, i.e. performs a prescribed condition M<N at step 234 and moves to step 236. The node B controls the value of the delay range of the support so that it exceeded the original value of the delay range at step 236, that is, performs the selection of the values of delay for the process of range of support in the prescribed condition C>And at step 236 and moves to step 238. The node B controls the number N of the original KM, so that it exceeded the number of L KM of the request bandwidth or the number M support KM at step 238, that is, performs the selection of the original KM on the stage 238 in the prescribed condition N>M or L at step 238, and then proceeds to step 240. The node B controls the value And postponement of the original range so that it is less than the value of B delay range selection query bandwidth or the value of the delay range support at stage 240, that is, performs the selection of the values of the delay to process the source range when the prescribed condition a<B or C at step 240, and then proceeds to step 242.

The node B creates a message Kartals with many KM are classified in accordance with the objectives of the range shown in table 3 at step 242, and moves to step 244. In this case, KM is classified according to recognize the efforts of KM, KM to request bandwidth and KM support in accordance with such tasks range. Node B inserts the values of the delay, in response to the type of KM, are shown in table 4, the message GQVLS at step 244 and transmits the message Kartals and message GQVLS having values of delay to the necessary.

To perform the selection code range and highlight the value of postponement in accordance with objective selection range will be described below with reference to figure 3.

Figure 3 shows an algorithm illustrating a procedure for assigning KM and the value of delay for the software in accordance with objective selection range, according to a preferred variant implementation of the present invention.

As shown in figure 3, receives a message from node B and moves to step 312. SW determines at step 312 whether the received message is a message Kartals. If the received message is a message Kartals at step 312, passes to step 314. Analyzes the message Kartals in order to verify KM, i.e. the original KM, KM request bandwidth and KM support at stage 314. If these MILES were checked at step 114, then passes to step 322. However, if it is determined that the received message is not a message Kartals at step 312, then passes to step 316. Identifies on this is e 316, whether a received message is an GQVLS. If the received message is not a message GQVLS at step 316, then goes to step 318. BY processing the message corresponding to the received message at step 318 and ends the program.

Meanwhile, if the received message is a message GQVLS at step 316, then passes to step 320. Analyzes the message GQVLS in order to check the values of grace KM, which are contained in the message GQVLS, that is, the value of postponing the original KM, the value of deferral KM to request bandwidth and the value of deferral KM support, at stage 320, and moves to step 322, sets the transform between proven KM and their values, delay at stage 322 and moves to step 324. SW determines at step 324 whether it is the aim of the current range selection task source range. If at step 324 it is determined that the aim of the current range selection is the task of the source range, then passes to step 326. ON selects at step 326 original MILES and it is grace from among the values of the transformation at step 320, and moves to step 334. If at step 324 it is determined that the aim of the current selection range is not part of the original range, it moves to step 328. SW determines at step 328 whether zadachakh range goal range selection query bandwidth. If at step 328 it is determined that the aim of the current range selection is the task of a range selection query bandwidth, then passes to step 330. ON selects KM of the request bandwidth and the delay value from among the values of the transformation at step 330, and moves to step 334. If at step 328 it is determined that the aim of the current selection range is not a problem of range query bandwidth, then passes to step 332. ON selects KM and its value cutoff of the number of values of the transformation at step 332, as the aim of the current selection range is a Troubleshooting tasks range selection support, and moves to step 334.

After select the current target KM and the value of delay in any one of steps 326, 330 and 332, it performs the access uplink communication with the selected KM, and its value delay at stage 334 and moves to step 336. If the software does not accept the response to the access uplink communication within the prescribed period of time at step 336, it is determined that the conflict codes in the access uplink connection, and returns to step 324. ACCORDING performs a series of operations to access the upward communication line in accordance with the task of selecting the range and value of the delay at step 324. Meanwhile, eclipe receives a response to the access uplink communication within the prescribed period of time at step 336, then determine what conflict does not occur when accessing the upward communication line, that is, determine what is normal access to the upward communication line, and then move on to step 338. UPON completing the transmission of the access uplink communication or performs other operations transfer on stage 338.

As can be seen from the previous description, the node B communication system based on the schema MDRC assigns different KM and their values delay the process range in accordance with the objectives of the range, and informs about the result of such selection, which leads to the minimal number of conflicts uplink communication. The node B dynamically assigns the number of KM and their values deferral processes range in accordance with the status of the cell and the task of selecting the range that results in the minimum delay time of the access uplink connection.

FIELD: communications.

SUBSTANCE: mobile station (MS1,…,MS10) initiates a call, which contains query for priority access. If system lacks resources for immediate processing of call, initiation message is processed by base station (BS1, BS2) and mobile communication commutation center with use of large number of message transfer protocols for determining time, when call was initiated, and priority, related to current call. On basis of priority and time of call base station places the call to queue, while calls with higher priority get better position in queue, then calls with lesser priority. Calls with similar priorities can be placed in queue according to time of receiving each call. When system resources become available, waiting call with higher priority is granted a channel, and call is processed normally.

EFFECT: higher efficiency.
