Abstract

The present invention integrates resource allocation between time division duplex (TDD) and frequency division duplex (FDD) in wireless communication systems. A radio network controller (RNC) receives a radio access bearer (RAB) request from a core network or a wireless receive/transmit unit. The RNC utilizes a TDD-FDD selector to assign radio resources in response to the request. The TDD-FDD selector evaluates various parameters regarding the received RAB request and determines whether it is preferable to assign TDD resources or FDD resources and whether such resources are currently available. Once resources are assigned, system conditions are evaluated to determine whether optimizations may be made to a current resource allocation.

200522635 V. Description of the invention (1) Field of the invention The present invention relates to a wireless communication system. More particularly, the present invention relates to integrated resource allocation between time division duplex and frequency division duplex in a wireless communication system. Background Wireless communication systems are well known in the technical field. To provide global connectivity for wireless systems' standards have been developed and implemented. One of the widely used standards is known as the Global System for Mobile Telecommunications (GSM). This is regarded as the so-called second-generation mobile radio system standard (2G) and its revised version (2.5G). GPRS and EDGE are 2.5G technologies that provide a relatively high-speed data service at the top of the (2G) mobile telecommunications global system network. Each of these standards seeks to improve upon previous technical standards with additional features and enhancements. In January 1998, the European Telecommunications Standards Institute-Special Action Group (ETSI-SMG) agreed to wireless access planning for the third generation wireless system known as the Global Mobile Telecommunications System (UMTS). To further implement this global mobile telecommunications system standard, the 3rd Generation Partnership Project (3GPP) family was formed in December 1998. The third-generation partnership plan continues to be implemented on the common third-generation mobile wireless standard. A typical global mobile telecommunications system architecture according to the current Third Generation Partnership Program Specification is depicted in Figure 1. The global mobile telecommunications system network architecture includes a core network connected to the global mobile telecommunication system land helmet H (ϋ TRA Ν) via I u, which is known to be defined in detail in the current public third-generation partner planning documents.路 (c Ν). The Global Mobile Telecommunications System 'Universal Terrestrial Wireless Access Network System is configured to be provided via wireless transmission and reception units (WTRUs) of user equipment (UEs) known as third generation partners' via a wireless interface known as Uu Wireless communication services to users.

The connection and wave point of the special frequency communication service is based on the development of the wireless connection mode field and another important functional partner. The background of the speed data has wireless time-sharing dual and downlink rate carriers. There is no point at all. It is not only the communication system between the communication system and the system, but also one that can be packaged as much as planned. Specific information Communication system Industrial system Channel channel ’Is the frequency to be connected to the ground? Envelope power and the dual-feed system with machine-in-machine are all in the middle. The fractional factor is based on the frequency division and transmission satellite circuit switching secrets, complete work, frequency division, and dedicated disclosure. The special field of the radio system of the single frequency duplex system. protection. The duplex system is the channel system and continues to be connected to the next channel in the time domain link. On the carrier system, the majority of the communication systems of the wireless network controller are combined to transmit and develop. Traffic uses both in the same. Therefore, the direction of the system is to alternate between the two frequency bands. The development of the implementation of the sub-system by the US Honeycomb Wireless System is carried by the system's traffic category, including voice communications, as well as various types of data communications. The multimedia data transmission system on the system usually generates uplink symmetrical traffic load. In addition, the coverage area coverage of wireless user scorable frequency duplex type systems is known to increase the connection frequency by 4 °. In the time-sharing dual-guard system, the uplink and downlink are connected. The situation is adjusted dynamically. It is said (or unbalanced) that the traffic is appropriate. 2 The high data rate is wrong. However, the frequency-division duplex system has more time-division duplex.

P.200522635 V. Description of the Invention (5) The advantages of the (5) system are better. Due to the predetermined allocation of uplink and downlink resources, the frequency division duplex system is more suitable for processing data rates that have a downward relaxation such as voice traffic. Fixed data rate service. The radio resource management between the time-division duplex system and the frequency-division duplex system is implemented individually in each system type according to its self-allocation method. This arrangement eliminates potential optimizations that can be achieved by integrating resource allocation between time division duplex and frequency division duplex in a wireless communication system. Therefore, it is necessary to integrate radio resource management between time division duplex and frequency division duplex in the wireless communication system. SUMMARY OF THE INVENTION The present invention integrates resource allocation between time division duplex and frequency division duplex in a wireless communication system. The radio network controller can receive radio access bearer (RAB) requests from the core network or the radio receiving / transmitting unit. The wireless network controller can use time division duplex-frequency division duplex selector to allocate wireless resources back and forth as required. The time-division duplex-frequency duplex selector can evaluate various parameters related to the received radio access bearer and decide whether to better allocate time-division duplex resources or frequency-division duplex resources, and whether the resources are currently available. Get. Once resources are allocated, system conditions are evaluated to determine whether the current resource allocation can be optimized. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the accompanying drawings, wherein like numbers throughout the text represent like elements.

Referring now to FIG. 2, a wireless communication system 200 according to the present invention is shown. The system 2000 includes a time division duplex wireless network controller 204 and a frequency division duplex wireless network controller 208 connected to a core network 202. Each wireless network controller 204, 208 controls at least one base station. For example, the time division duplex wireless network controller 204 controls the base station 2 1 2. The base station 2 1 2 sequentially provides a coverage area 2 1 0, of which the wireless transmission / reception unit 228 operating in the coverage area 2 1 2 0, 2 3 0 can be allocated from the time division duplex wireless network controller 2 0 4 Resources. Similarly, the frequency-division duplex wireless network controller 2008 can control the base stations 216 that sequentially provide the coverage area 214. The WTRU 0, 2, 2 2 can be allocated resources from the frequency division duplex wireless network controller 2008. In area 218, WTRUs 224 and 226 can obtain time division duplex and frequency division duplex services. For example, the overlapping coverage area of area 2 1 8 can be of any size 'and the specific arrangement shown in Figure 2 is for illustration only. When a radio access bearer request (that is, a call-setup request) is transmitted from the core, radio, or wireless transmission / reception unit to the radio network controller, it is often accompanied by information about how the requested connection is sent? Examples of parameters include, but are not limited to, the up-chain and the down-chain: the symmetric or symmetric state of the interval rate r ^ size // // connection), the data transfer pair ί * f type, and whether the connection is required to be point-to-point, and the point-to-point 5 / broadcast . The above parameters are only examples, and any type of parameter providing information about the requested connection can be used.

Description of the invention (7) The frequency is duplex frequency selector 206, 210. The time division duplex-frequency division duplex selector 2 0 6 ′ 2 1,0 may be as expected one or more processors used to determine the most technological type of radio access bearer requirements to be received. That is, based on, for example, 2-line access bearer requirements, resource availability, and / or any other relevant parameters, based on time-sharing duplex-frequency-division duplex selectors 206, 2JI 0 works with & the sub-functions of the radio network controller that includes its radio resource manager (RRM) to allocate resources so that the connection request can handle the most efficient system technology type for a particular type of i connection request. distribute resources. / Column > If ^, '^ are not considered as the main consideration, the connection requirements for symmetrical traffic will be similar to the traffic in the uplink and downlink) It is better to implement frequency division double 8 locations / mile > Similarly, connection requirements with asymmetric traffic (that is, one guard and two dragons ί Ϊ Ϊ are larger than in the other direction) are preferably implemented in a time-sharing double 042 method.

It is estimated that the data rate of the on-chain and iff-on-chain is required. At present, the information rate of Weng Teng Jin, and the chain capture rate can be estimated based on 2 ^ = number. ^ 时 双 ^ / ^ /// Any other 206,210 can then be compared with the estimated difference ^ Zhai.

i Ϊ t f The right traffic is very asymmetric with the high data rate, so double time is better. If the traffic is very symmetrical with a fairly low data rate, then ^, double ί is better. In the meantime, any transaction can be transmitted to the time-sharing dual-guard S frequency-division duplex according to the situation. For example, if time-sharing duplex congestion, the radio access bearer requirement can be allocated to frequency-division duplex regardless of the others. Star Festival is possible In this embodiment, it should be noted that the radio access bearer requirements can be generated by the industrial wireless network controller 204 or the frequency division duplex wireless network controller 208H. In either case, the receiving network controller can make a source allocation decision and forward the wireless access bearer request to an appropriate network controller type if necessary. For example, the time division duplex wireless network controller 204 receives the request from the wireless network controller and decides that it should use a frequency division duplex I-type technology. The time division duplex wireless network controller 204 The 丨 ur interface transfers this request to the frequency division duplex wireless network controller 208. The crossover radio network controller 208 then handles the request in the normal manner. also

Then, this parameter can provide information about the received wireless access. &Quot; Estimation β is as above, it is better to be evaluated. The parameters include symmetry and data information. Usually, in step 4 06, the rate and application type evaluated in step 4 04 are used.

Page 21 200522635 V. Description of the invention (16) Start frequency division duplex / time division duplex transfer. Typical policy items include: 1) service quality (QOS); 2) service; 3) management; and 4) behavior, but can include any additional items expected. A service quality policy defines service quality conditions such as power or quality thresholds. Service policies are defined as service characteristics such as data rate asymmetry or real-time (RT) services (such as voice calls) versus non-real-time (NRT) services (such as webcasts). A management policy defines operating, managing, and maintaining (0Α & M) conditions. This contains an immediate policy ’or a non-immediate view of maintenance applied to load balancing purposes. A behavior policy defines one or more user behavioral conditions, such as user location or speed. The policy department is defined as the system configuration part and can be independent or interdependent. For example, 'management policies take precedence over service quality or service policies. Relevant inputs for each policy are entered into the policy server. The input to the policy server is provided by the general radio network controller control logic, radio resource manager functions or external entities such as operation, management and maintenance functions. This policy can be defined or configured as expected, and this service requirement is handled as expected in frequency-division duplex mode or time-division duplex mode. When receiving a new call or handover request, the time-division duplex-frequency duplex selector 702 requests the policy server to make a decision on the appropriate mode of communication. Time division duplex—frequency division duplex selector 702 can perform the selection of the appropriate communication mode or the transfer between frequency division duplex mode and time division duplex mode in accordance with the decision made by policy server 706. Fig. 8 is a flowchart of 800 for handover processing between the time division duplex mode and the frequency division duplex mode according to the present invention. Initially, the wireless transmitting / receiving unit establishes communication in a specific communication mode (step 802). Wireless transmitting / receiving unit

Page 22 200522635 V. Description of the invention (17) Then request specific services, such as web browsing (step 804). The wireless network controller 7 0 0 then determines whether one or more predetermined policies meet the service requirements such that a communication mode transfer should occur (step 8 0). If one or more policies are met (such as service quality, location, speed, etc.), the policy server 7 06 can indicate the communication mode that the service should be approved, and the wireless network controller 7 0 0 can follow the label To perform the transfer of the communication mode (step 8 0 8). If not, the wireless network controller 700 can maintain the current communication mode (step 8100). For example, when a voice call arrives and the WTRU is in a time-sharing duplex mode, the relevant input for each policy is entered into the policy server. If one or more policy conditions for time-division duplex to frequency-division duplex handover are met, the policy server 7 0 6 can indicate that the transition to time-division duplex mode should occur and the wireless network controller 7 0 0 can be executed to shift to the duplex mode. It should be noted that although only one wireless network controller of each type of wireless network controller (ie, frequency division duplex or time division duplex) is shown to illustrate the present invention, any time division duplex wireless network controller and Frequency duplex wireless network controllers are available. In this arrangement, wireless network controllers of the same type of communication typically use their individual I u r protocols. It should also be noted that the various individual or cluster functions and protocols described herein may be performed using any number of processors as expected.
