Method and Apparatus for Reallocating Frequency of Mobile Communication Terminal in Mobile Communication Network {Method and Apparatus for Relocating the Frequency of Mobile Communication Terminal in Mobile Communication Network}

The present invention relates to the reallocation of the frequency of the mobile communication terminal, and more particularly, the HSPA dedicated frequency allocation for high speed data users in a wideband code division multiple access (WCDMA) network using high-speed packet access (HSPA) technology. In case of operating Allocation (FA), it is determined whether certain conditions are satisfied and reallocated frequency of mobile communication terminal to HSPA dedicated frequency to provide faster data service to mobile communication users and operate mobile communication network more efficiently. It relates to a method and apparatus that can be.

With the rapid development of communication technology, various wireless communication services using a wireless network have been provided. Recently, wireless Internet services, which provide communication services including the Internet through mobile communication terminals and wireless communication networks, have been in the spotlight, especially when a user moves without restriction of a place. As a result, users can freely move anytime, anywhere and talk to the other party, and can use various information such as text, voice, image, video, and other useful life information through the wireless Internet service. It can be provided in the form.

Such mobile communication systems have evolved over several generations. The first generation is an analog method, which is an advanced mobile phone systems (AMPS) system capable of only voice calls, and the second generation is divided into a digital system, a global system for mobile communication (GSM) and a code division multiple access (CDMA). CDMA is a method adopted by Korea and is divided into cellular and personal communication service (PCS) according to which frequency is used. Recently, IMT-2000 (International Mobile Telecommunication-2000), a third generation high speed data communication, has been used. IMT-2000 was developed for personal mobility guarantee and high-speed data transmission to ensure mobility between countries by integrating systems of countries using different radio access standards, and separated into synchronous CDMA 2000 and asynchronous WCDMA. Developed.

The WCDMA system aims at 2Mbps in indoor and pico-cell environments and 384kbps in typical wireless environments. However, as the wireless Internet is becoming more common and the number of subscribers is increasing, more various services are emerging, and higher speeds are required to support them. Accordingly, research is being conducted to provide high-speed transmission rates by evolving the WCDMA network in the 3GPP (Third Generation Partnership Project). Among these, a representative system is HSPA (High-Speed Packet Access).

HSPA is a combination of High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA). HSDPA was standardized in the March 2002 3GPP Release 5 specification and HSUPA in the December 2004 Release 6 specification. Initially, the maximum data rate of HSDPA handsets was 1.8Mbps, but now it is going to exceed 3.6Mbps and 7.2Mbps and ultimately exceed 10Mbps. For HSUPA, data rates are expected to be around 1 to 2 Mbps in the early stages and 3 to 4 Mbps in the next stages.

HSPA may be added to an existing WCDMA frequency or may be serviced as a separate new frequency for high capacity high speed service. In either case, HSPA and WCDMA systems share all the network components of the core network, including Radio Network Controller (RNC), Serving GPRS Support Node (SGSN), and Gateway GPRS Support Node (GGSN). And antenna cables and the like in common. Upgrading from WCDMA to HSPA requires new software packages and some hardware added to the base station and RNC to support high-speed data services.

When the HSPA technology is linked with the WCDMA network, it is desirable to operate a dedicated HSDPA and HSUPA FA to provide more efficient service. That is, the basic call is processed in a normal cell having a FA providing a low speed HSDPA and a DCH, and when a specific condition is satisfied, for example, when a high speed data transmission is required, a high speed HSPA dedicated FA is used. By reassigning frequencies, it is possible to provide services specialized for each user. In order to properly operate the WCDMA network using the high speed HSPA dedicated FA, an efficient algorithm for transitioning from the general FA to the high speed HSPA dedicated FA is required.

Accordingly, the present invention provides a more optimized algorithm for the high speed packet access dedicated frequency when the high speed packet access dedicated frequency is set in the mobile communication network using the HSPA technology. By reallocating through the service, the purpose of the present invention is to provide a method and apparatus for more efficient operation of a mobile communication network by improving the system's support for HSPA terminals supporting high transmission speeds in the future and improving data throughput in a cell. There is this.

The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention, which are not mentioned above, can be understood by the following description, and more clearly by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

According to an aspect of the present invention, there is provided a method for reallocating a preset frequency of a mobile communication terminal to a high speed packet access dedicated frequency in a mobile communication network, the method comprising: checking whether the terminal is a terminal capable of supporting high speed packet access, Checking whether the maximum data transfer rate of the terminal capable of supporting packet access satisfies a condition for a predetermined threshold rate, an actual data rate of data transmitted to the terminal capable of supporting high speed packet access, or the terminal Measuring any one of the data amount to be transmitted from the terminal, and if either the actual data transmission rate or the data amount satisfies a condition for a predetermined threshold, the preset frequency of the terminal is dedicated to the high speed packet connection. Include steps to reassign to frequencies And the one that features.

According to the configuration of the present invention as described above, when a dedicated high-speed packet access frequency is set in a mobile communication network using the HSPA technology, it is determined whether or not a predetermined condition is satisfied when the mobile communication terminal requires high-speed data transmission. If the system is satisfied, it provides an optimized method of reallocating the preset terminal frequency to the dedicated packet access frequency, enabling high-speed data transmission while utilizing the existing WCDMA system without additional network expansion or major change of call procedure. As a result, more efficient mobile network operation is ensured by maximizing throughput in the cell.

In addition, since it is possible to transmit a large amount of data at the same time, it is possible to complete the data transmission in a short time, thereby reducing the buffering time when using a video service, news service, real-time broadcasting services, etc. that require a large amount of data transmission In addition, since the quality of the overall service is improved, such as high-definition service, the user's service satisfaction can be improved.

The above objects, features, and advantages will be described in detail with reference to the accompanying drawings, whereby those skilled in the art to which the present invention pertains may easily implement the technical idea of the present invention. In describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Table 1 shows the categories according to the capabilities of the HSDPA terminal. The HSDPA function is supported by the terminal. The terminal supporting the HSDPA function belongs to one of 12 categories, and the maximum downlink data rate varies from 0.9 Mbps to 14.4 Mbps according to the supported category.

Max number of HS-DSCH codes MAC layer throughput Category 1 5 1.2163 Category 2 5 1.2163 Category 3 5 1.8245 Category 4 5 1.8245 Category 5 5 3.649 Category 6 5 3.649 Category 7 10 7.2055 Category 8 10 7.2055 Category 9 15 10.1255 Category 10 15 13.976 Category 11 5 9.075 Category 12 5 1.815

As such, the throughput for each category is different. In addition, the terminal must use a lot of downlink code resources to provide its maximum throughput. Therefore, if a high-speed data transmission is required by setting up and operating an HSDPA dedicated FA for more efficient mobile network operation, the frequency is reassigned to this dedicated FA, and a general FA is used to allocate low-speed HSDPA calls, existing voice services, and video services. You can think of ways to accommodate it.

This can be similarly applied in HSUPA. When many users are connected to the network using HSUPA, the data transmission rate is very high depending on the amount of noise flow in the system or the fairness of the user and the amount of UL DCH (AMR, CS64k, PS DCH). It is fluidly scheduled. Therefore, if a mixed configuration (DCH + HSDPA + HSUPA) is used for all frequencies, there is a problem of low efficiency in resource utilization. Therefore, it is conceivable to operate HSUPA dedicated FA separately for HSUPA.

FIG. 1 is a flowchart illustrating a method for reallocating a preset frequency of a mobile communication terminal to a high speed packet access dedicated frequency during HSDPA dedicated FA operation according to an embodiment of the present invention. To explain this, we first need to understand some things.

FIG. 2 is a diagram illustrating an example of cell configuration for each FA during 3FA operation. In order to explain an embodiment of the present invention, it is assumed that a mobile communication network composed of 3FAs is used as shown in FIG. 2. This is an example of operation when setting up a dedicated FA, and cell composition for each FA may vary according to subscriber capacity and subscriber inflow. Referring to FIG. 2, 1FA and 2FA use DCH & HSDPA cell setup and 5 HSDPA HS-DSCH codes, and 3FA is a high-speed data only FA and DCH & HSDPA cell setup and HSDPA HS-DSCH code 10 And HSUPA cell settings.

In the present invention, the compression mode is used to determine the HHO (Hard Handover) from the frequency of the terminal set to the high-speed packet access dedicated frequency. FIG. 3 is a diagram illustrating parameters and a description related to a compressed mode. First, the terms described in FIG. 3 will be described.

TGPRC (Transmission Gap Pattern Remaining Counter): Number of TG patterns in TGPS

TGPS (Transmission Gap Pattern Sequence): Combination definition of Transmission Gap Pattern, maximum 6

Transmission Gap Sequence Number (TGSN): offset value of the starting point of the TG

TGL (Transmission Gap Length): Transmission Gap length, up to 14 slots

TGD (Transmission Gap Distance): Distance between TG and TG, in slot unit

TGPL (Transmission Gap Pattern Length): Length of TG pattern 1

The terminal compresses and transmits sufficient data during the compressed period, thereby searching for the target FA during the secured time and measuring the signal quality of the FA. The measured value is sent to the RNC, and the RNC determines whether to HHO after determining the adequacy of the measured signal quality.

When the terminal attempts to connect to the first call, the system unconditionally connects the terminal to 1FA or 2FA. If the terminal is already connected to 1FA or 2FA, the terminal accepts the frequency as it is, and if connected to 3FA, the frequency is set to 1FA or 2FA in the RRC connection setup step to induce the transition of frequencies. At this time, the transition to 1FA or 2FA is determined according to the cell load state for each frequency, and each definition follows the WCDMA RRM procedure.

Referring now to FIG. 1, first, the RNC checks an access stratum version of a terminal (100). Release 5 supports HSDPA and Release 6 supports HSDPA and HSUPA, so if the access layer of the terminal is Release 5 or Release 6, it can be determined that the terminal supports HSDPA. This check command is sent when an RRC connection is requested. 4 shows a configuration of an RRC connection request command. If the condition is not satisfied, the terminal maintains the frequency set as it is (106).

After checking the access layer version of the terminal, the system may receive a high HSDPA UE_Cat, a High HSDPA_data rate, and a High HSDPA_data rate_period value (102). These parameters are used as thresholds in the following steps.

If it is determined that the terminal can support HSDPA through the terminal's access layer check, the RNC checks the maximum data transmission rate of the terminal. In the following steps, the actual data transmission rate is compared with the threshold to determine whether to transition to a high-speed packet access dedicated frequency. If the maximum transmission rate of the terminal does not reach this threshold, there is no need to measure the actual data transmission rate. Because. For example, if a terminal is a Category 1 terminal with a maximum data transfer rate of about 1.2 Mbps, and the terminal will only transition to a high speed packet access dedicated frequency when the actual data transfer rate is 3 Mbps or more, then the terminal will no longer operate at the high speed packet access dedicated frequency. It is not necessary to determine whether or not the transition. Since the maximum data transfer rate of such a terminal varies depending on the category of the above-mentioned terminal, the RNC can check the maximum data transfer rate of the terminal by checking the category information of the terminal. Accordingly, the RNC checks whether the category of the terminal is equal to High HSDPA UE_Cat in order to check whether the terminal supports the category coming up with the completion of the RRC connection (104). High HSDPA UE_Cat may have one or more values, and thus may support terminals having various categories. For example, if you want to determine whether to transition to a high-speed packet access dedicated frequency only for terminals with a maximum data transfer rate of 7 Mbps or higher, you can specify the High HSDPA UE_Cat value as category 7, 8, 9, 10, and the terminal with the corresponding category. You only need to measure the actual data rate. If the category of the terminal is not equal to High HSDPA UE_Cat, the terminal maintains the frequency set as it is (106). 5 shows command formats and parameters used to determine whether a terminal supports a category.

If the terminal meets all of the predetermined conditions as a result of the access layer version and the category check, the terminal may be regarded as selected for the transition to the high-speed packet access dedicated frequency. The RNC monitors the transmission speed of data transmitted from the system to the terminal in the next step (108). In the case of HSDPA, since each terminal has a buffer set in the Mac layer, when the data transmitted through the buffer is measured, the data transfer rate to the actual terminal can be calculated and used.

The RNC now checks if the measured data transfer rate is maintained above the High HSDPA_data rate for a time above High HSDPA_data rate_period (110). This is substantially a step of checking whether the terminal needs high speed data transmission. For example, if High HSDPA UE_Cat is defined as categories 7, 8, 9, and 10, 3 Mbps, which is close to 3.6 Mbps, which is a terminal throughput of Category 6, which is one lower than 7, which is the lowest category, may be set as the High HSDPA_data rate. In this case, if the transmission speed of 3Mbps or more is sustained for a certain time, that is, it can be accommodated as a high-speed packet access FA starting from categories 7, 8, 9, and 10. If the check does not satisfy this condition, the RNC continues to monitor the data transmission rate to the terminal (108).

If the data transmission rate check confirms that the high HSDPA_data rate is maintained at or above the High HSDPA_data rate, the RNC sends the aforementioned compression mode command to the terminal to activate the compression mode, and the terminal activates the compression mode along with the activated compression mode. FA measurement is performed (112). That is, the terminal searches for a high-speed packet access dedicated frequency during the free time caused by activation of the compression mode, and if the frequency is found, the signal quality of the frequency, for example, CPICH Common Pilot Channel Received Signal Code Power (CPICH) or CPICH Ec / Measure the Io value.

After the RNC receives the Inter FA measurement result measured and transmitted by the terminal, the RNC checks whether it is equal to or greater than a predefined Inter FA HHO threshold (114). Even if the terminal requires high-speed data transmission, the transition of the frequency may not be necessary if the signal quality of the high-speed packet connection dedicated frequency to be transitioned is not good. Therefore, the RNC reassigns the frequency of the terminal only when it is determined that the signal quality of the high-speed packet access dedicated frequency is higher than a certain level by comparing the measurement result transmitted from the terminal with its own threshold. If it is confirmed that the predetermined level or more, the RNC performs the HHO with the HSDPA dedicated frequency at the preset frequency of the terminal (116). If the signal quality of the high-speed packet access dedicated frequency is less than the predetermined level of the terminal already set without the HHO The frequency remains the same (106).

Similar to the frequency shifting method in the above-described HSDPA-only FA operation, a similar frequency shifting method can be considered in the HSUPA-only FA operation. First, the frequency shift method for HSUPA-only FA operation is briefly explained as compared with HSDPA. Initially, the RNC checks the access layer version of the terminal, but HSUPA selects Release 6 only. This is because Release 5 does not support HSUPA. In the category checking step of the terminal in the call connection step, it is checked whether the HSUPA support field of the RRC connection setup complete exists.

After reassigning the frequency of the terminal from the general frequency to the high speed packet access dedicated frequency, a step of reallocating the terminal frequency back to the general frequency may be added if necessary. For example, at the threshold entry stage, Low_HSDPA_data rate and Low_HSDPA_data rate_period may be defined, and then the data rate may be compared with these thresholds and used as a reference for reassignment to normal frequencies.

In the case of HSDPA, the transmission rate of the data transmitted to the terminal is measured and used as the reference for the transition to the high-speed packet access dedicated frequency. In the case of HSUPA, the transition reference can be determined through two methods. First, as with HSDPA, the data transfer rate in the Mac layer buffer is measured to compare the data transfer rate with thresholds, for example HSUPA_data rate and HSUPA_data rate_period. That's how. Since this method is performed in the same manner as the above-described HSDPA dedicated frequency shifting method, a detailed description thereof will be omitted. The second method is to measure the amount of data to be transmitted from the terminal to the system in advance and receive the measurement from the RNC to determine whether to transition. That is, when a call is established, the system transmits a measurement control command to the terminal, and after receiving the message, the terminal transmits a certain message back to the system when the condition is satisfied based on the condition received from the system. The system then determines whether or not to shift the frequency. The second method will be described in detail below.

FIG. 6 is a flowchart illustrating a method for reallocating a preset frequency of a mobile communication terminal to a high speed packet access dedicated frequency during HSUPA dedicated FA operation according to another embodiment of the present invention. First, the system receives parameters for Event 4a and Event 4b (600). Event 4a means that when the terminal is set to the normal frequency and the amount of data to be transmitted to the system is greater than the threshold value, transition to the high speed packet access dedicated frequency is required. In the set state, it means that the amount of data to be transmitted to the system is less than the threshold value and transition to the normal frequency is required. The parameters for Event 4a / 4b refer to the variables and thresholds for these conditions.

The RNC checks the access stratum version of the terminal (602). Since Release 5 supports HSDPA and Release 6 supports HSDPA and HSUPA, it can be determined that the terminal can support HSUPA only when the access layer of the terminal is Release 6. This check command is sent when an RRC connection is requested. If the condition is not satisfied, the terminal maintains the frequency set as it is (606).

Next, the RNC checks whether the terminal can support HSUPA (604). This is done by checking if the HSUPA support field of RRC connection setup complete exists as mentioned above. If the condition is not satisfied, the terminal maintains the frequency set as it is (606).

If the above two conditions are satisfied, the RNC transmits a measurement control message for Event 4a at the normal frequency to the terminal (608). 7A to 7B illustrate the configuration of a measurement control message transmitted to a terminal. This is a message for the terminal to measure the amount of traffic (Traffic volume) to be transmitted from the terminal to the system. The terminal continuously monitors this amount of data and compares it with the threshold received from the system. As a result, if the amount of data to be transmitted to the system in the state set to the normal frequency is greater than the threshold, the terminal notifies the system of the occurrence of Event 4a with the measured value (610). 8 is a graph showing a criterion for determining Event 4a and Event 4b to be described below.

The terminal receiving the measurement control message while the connected frequency is set to the general frequency transmits the measurement result to the RNC when Event 4a occurs (610). The RNC transmits the aforementioned compression mode command to the terminal to activate the compression mode, and the terminal performs inter FA measurement with the activated compression mode (612). That is, the terminal searches for a high-speed packet access dedicated frequency during the free time caused by activation of the compression mode, and if the frequency is found, the signal quality of the frequency, for example, CPICH Common Pilot Channel Received Signal Code Power (CPICH) or CPICH Ec / Measure the Io value.

After receiving the Inter FA measurement result measured and transmitted by the UE, the RNC checks whether the RNC is equal to or greater than a predefined Inter FA HHO threshold (614). Even if the terminal requires high-speed data transmission, the transition of the frequency may not be necessary if the signal quality of the high-speed packet connection dedicated frequency to be transitioned is not good. Therefore, the RNC reassigns the frequency of the terminal only when it is determined that the signal quality of the high-speed packet access dedicated frequency is higher than a certain level by comparing the measurement result transmitted from the terminal with its own threshold. If it is confirmed that the predetermined level or more, the RNC performs the HHO with the HSUPA dedicated frequency at the frequency already set in the terminal (616).

In this state set to the HSUPA dedicated frequency, the RNC transmits a measurement control message for Event 4b in the HSUPA dedicated FA (617). The terminal continuously monitors the amount of data to be sent. If the amount of data falls below a threshold, the terminal notifies the system of occurrence of Event 4b (618). The RNC sends a compression mode command back to the terminal to activate the compression mode, and the terminal performs Inter FA measurement with the activated compression mode (620). After receiving the Inter FA measurement result measured and transmitted by the terminal, the RNC checks whether it is below a predefined Inter FA HHO threshold, and if it is determined to be below a predetermined level, the RNC performs the HHO at a general frequency at a dedicated frequency of HSUPA. (622).

The HSDPA dedicated frequency and HSUPA dedicated frequency shifting algorithms may operate separately, or may operate simultaneously when the conditions of the two modes are satisfied at the same time.
