The technical field to which the invention relates

The present invention generally relates to a method for configuring and updating information of the connection identifier (CID, IP) in the communication system, wireless broadband access (BWA, shbd) and, in particular, to a method for configuring and updating IP based on a series of flows of services between the base stations (BS, BS) and mobile station (MS, PS).

The level of technology

Modern development of communication technologies has increased the users ' requests for more high-speed transmission/reception of large amounts of data. In this context, the group 802.16 standardization Institute of engineers in electronics and electrical engineering (IEEE) conducts research to provide service shbd in PS.

The IEEE 802.16 standard defines the schema of the high-speed data transmission/reception for PS.

SS transmits and receives data via the connection, at least one service from the BS. Many compounds of services identify with their particular IP.

During the installation of new service connections between SS and BS BS assigns an IP that identifies the service connection with PS. IP services must have a unique value, such that they can be clearly visible in a single cell at the base station. Therefore, the use of IP is limited to one cell and IP can be used for the van when another connection services in another cell.

When the PS moves from an old cell to a new cell, or when the PS updates all existing connections services serving BS and preregistered with the serving BS in the communication system, shbd, the new BS or the serving BS assigns a new IP for each connection service with PS. During the transfer service to the new BS or re-connection with the serving BS PS receives a new IP from a new BS or the serving BS using the message management control the medium access (MAC DCP).

In the traditional process, the new IP appoint PS, i.e. IP update for PS in the following way. The BS transmits in PS update information of IP, including existing IP and new IP, ordered pairs. The transfer of existing IP is optional and causes the flow radioresource. If a COP uses a large number of IP volume information pack IP is great. In addition, if a large amount of information update IP issue for many cops, the whole communication system shbd experiencing a significant decrease in efficiency radioresource updates compounds.

Disclosure of invention

The present invention, essentially, is to solve at least the above problems and/or disadvantages and to provide at least the advantages opinie below. Still the way the present invention is to provide a method of configuration information update IP to a smaller volume in the communication system shbd.

The aforementioned problems are solved by providing a method of configuring and updating IP communication system shbd.

In accordance with one aspect of the present invention in method update information IP BS in a communication system shbd BS arranges at least one first IP is already assigned to the PS, in a predefined sequence, determines whether the second IP to replace at least one first IP converts the at least one first IP in the value of the bit in the bitmap in accordance with the definition and includes bitmap information updating IP and finishes the update information of IP by including the second IP in accordance with the binary value in bit map.

In accordance with another aspect of the present invention in the configuration information update IP to update the service connection between BS and SS in the communication system, shbd, in which the IP set on the basis of sequence flows, services, information of the first IP includes information field, in which the position of at least one of the first IP assigned to it in PS before upgrading connection, convert the bit map, and the information is which IP includes, at least one second IP, newly appointed in PS on the basis of the bitmap.

The implementation of the invention

The preferred implementation of the present invention will be described in this application below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail because they shade the invention with unnecessary details.

In the following description of a typical way to update the IP and the configuration of a typical information pack IP will be preceded by a variant implementation of the present invention. Regarding the concepts used in the present description, "the first IP refers to IP, which identifies the service that is connected between the substation and the old BS and the "second IP refers to IP, which is the new BS assigns in PS. When the PS must update an existing IP that is associated with the old BS old BS may assign a second IP COP or when the SS transmits the service to the new BS, the new BS may assign a second IP in PS. An example for the latter case.

1 and illustrates an example of the dependence of the conversion between IP services in the communication system shbd.

Referring to figure 1, the PC receives an IP from the BS, so the idea is to tapicerowane packages the sequence of flows of services. PS takes three services 10, 65 and 121 identified by the IP 138, 239 and 23, respectively, from the old BS 100.

When the PS moves from the old BS 100 to the new BS 200, IP 138 and 23 is changed to 4 and 124, respectively, in the refresh operation of the IP of the new BS 200. In the example illustrated in figure 1, the service IP 239 not serve in the new BS, the connection between the services complete. Therefore, IP 239 free. PS, which made the transfer to the new BS 200, now accepts service 10 and 121 with the updated IP 4 and 124, respectively, from the new BS 200.

Figure 2 illustrates a typical format of the information pack IP provided in the PS in the communication system shbd.

Now, referring to figure 1 and figure 2, the information 20 pack IP (Obnovlenie) has field encoding type-length-value (TLV TDW). Box 21 values configured with the opportunity to have the first IP (Staryi) and new IP (Novyi) TDW.

Table 1 below illustrates the encoding format TDW obnovleniya, as table 2 below illustrates the encoding format TDV first and second IP.

Table 2
NameType (1 byte)Length (1 byte)Value (variable)

Storyes16,22IP before sending the service

Value types in table 1 and table 2 set in accordance with the standards of IEEE 802.16. Each of the first and second IP represented using the type of one byte length of 1 byte and IP information of 2 bytes, with a total of 4 bytes of information.

The first and second IP encoded in a manner illustrated in table 1 and table 2, set in a field of 21 values so that the first IP 25 and the second IP 23 and the first IP 29 and the second IP 27 ordered pairs for the respective services. In the case of a typical obnovleniya, illustrated in figure 2, for example, when updating two IP field 21 size has only 16 bytes of information. Therefore, the delivery of the first IP together with the second IP causes losses radioresource.

Thus, the present invention provides a method of modifying the configuration information update IP to minimize the number is the primary objective information of the first IP included in the information pack IP. More specifically, the new BS 200 compresses all of the first IP assigned using the old BS 100, in the form of a bitmap. To accomplish this, the new BS 200 arranges the first IP in a predefined sequence (e.g., ascending or descending sequence) values IP and specifies in the bitmap, updated whether the first IP or not. The collation sequence can be a sequence of destination of the first IP using the old BS 100, the sequence of the recognition of the first IP using the new BS 200 or a predefined sequence.

When updating the first IP assigned using the old BS 100, the new BS 200 sets the value of the bits in the positions corresponding to the ordered first IP, 1-s, if the new BS 200 may assign a second IP to replace the first IP. However, if the service is provided using the old BS 100, not available for PS in the new BS 200 (for example, a service with the first IP 239 figure 1), the new BS 200 sets the value of the bit in the position corresponding to the position of the first IP, 0, so as to indicate that you have successfully updated service IP used with the old BS 100, the new BS 200.

Using field configuration of the first IP in the information update new IP this way, the first IP present in the bitmap. But what's IP replacing the old IP with the value of bit 1, the least significant bit (LSB, NASB) to most significant bit (MSB, Naesb) bitmap, ordered sequentially in the encoding format TDW following bitmap. Thus, the information update your new IP is properly configured, which will be described in more detail with reference to figure 3.

Figure 3 illustrates the data format information pack IP provided in the PS in the communication system, shbd, in accordance with the present invention.

As shown in figure 1 and figure 3, the information 30 update your new IP (Obnovlenie) of the present invention is composed of a set of fields TDW. These fields TDW divided into 33 bit cartilages representing services that have the IP assigned using the old BS, and which is available in the new BS, because the code of the bitmap first IP and region 35 and 37 nawagai, consistently presenting new IP, corresponds to the value of bit 1 in 33 bit cartilages.

Table 3 illustrates an example of encoding information 30 pack IP and table 4 below illustrates an example encoding of a bit cartilages 33, novagas 35 and nawagai 37.

After the bitmap is a list of new IP. The number of new IP is equal to the number '1' in the bitmap.

Value types except bit cartilages in table 3 and table 4, installed in accordance with the standards of IEEE 802.16. Each of the second IP 35 and 37 are represented using the type of 1 byte length 1 byte and IP information of 2 bytes, with a total of 4 bytes of information. Compared to traditional information pack IP bit cartastrophes 33 includes a field 331 of the bitmap indicates whether the second IP or not and for the respective first IP thus reducing the amount of information of the first IP.

Below is a description of an example of a configuration information update your new IP in accordance with the present invention with reference to figure 1.

The old BS 100 manages IP 138, 239 and 23, corresponding to the three respective services 10, 65 and 121. When the PS moves from the old BS 100 to the new BS 200, it is logged in the new BS 200. During the operation, update the IP when you register a new BS 200 is not necessary to assign a new IP for service 65, as the new BS 200 may not provide service 65 with the first IP 239 or PS no need to take the service of 65.

Then the new BS 200 configures the area a bit cartilages, illustrated in Figure 3, in order to configure the information update your new IP. The new BS 200 arranges the first IP 138, 239 and 23 in a predefined sequence (i.e., ascending or descending sequence) values IP and sets the values of the bits ordered for the first IP to assign or not assign a binary bit map. Specifically, the new BS 200 arranges the first IP 239, 138 and 23 in this sequence, converts ordered the first IP in bits, starting with Naesb under one-to-one and sets the bits for the first IP services 138 and 23, each 1, and bits of the first IP service 239 0. The result is that bit value ka is you equal to "011". In "011" "0" "239", "1" corresponds to "138"and the last "1" corresponds to "23".

The new BS 200 must assign a new IP for the second and the last bit "1". Figure 1 new IP is equal to "4" and 124". Therefore, "124", corresponding to the last "1", display field values novagas 35, and "4"corresponding to the second "1", display field values novagas 37. Despite the fact that the new IP display consistently in sequence, starting with Naesb, it is obvious that displays the new IP can be performed in sequence, starting with Naesb.

4 is a block diagram of a sequence of steps illustrating a method of updating IP between BS and SS in the communication system shbd in accordance with the present invention.

As shown in figure 4, upon receipt of a message of the registration request (REG-REQ, REC-REG) in step 401 new BS arranges the first IP assigned to it in PS using the old BS, in a predefined sequence (e.g., in accordance with the values of IP) in step 403. New BS determines whether to be updated ordered the first IP, at step 405, and determines whether the second IC to the first IC, step 407. If the second IP is assigned, the procedure goes to step 409; otherwise it goes to step 411. The second IP is equal to the value that new BS sets a random way. That is, the new BS creates a connection is the link for the available services, given the state of the resource, determines new IP for available services and inform the cops about the new IP in the update procedure of IP.

At step 409 the value of the bit corresponding to the first IP is set to 1 in the value field bit cartilages. At step 411 the value of the bit corresponding to the first IP is set to 0 in the field value field bit cartilages. New BS converts the value of the bits sequentially, starting with Naesb in the field a bit cartilages at step 413. Steps 405 through 411 repeat until until you have completed displays the first IP.

At step 415 the new BS encodes the second IP, the corresponding 1-persons in bit cartelage format TDW, thereby generating update information of IP. Update information for IP transfer in PS using the response message of registration (REG-RSP, RESP-REG) ZAP-REG.

For exact conversion between the first IC and the second IC, the first IC ordered according to the criteria previously established between the SS and the BS, such as the value of IP.

In accordance with the present invention, as described above, the new BS encodes at least one IP assigned to it in PS using the old BS, compressing the bit map, and creates a new IP in accordance with the bit values of the bitmap. Therefore, the amount of information updates is With, which takes PS transfer decreases and the result is increased efficiency radioresource.

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.
