Description of the Invention [Technical Field of the Invention] The present disclosure relates generally to communications, and more particularly to techniques for selecting a wireless communication network for acquisition by a wireless terminal. [Prior Art] ..., line pass L, material is a light-free network I network that enables non-terminals to communicate with * using an electron microscope or a wire. It is widely used to provide voice, video, and packet. Data, messaging, broadcasting, etc. ^ various communication services. Such wireless networks can benefit from such things as cellular networks: wide area networks (WWANs), wireless metro networks (wman), and wireless local area networks (WLANs). A wireless terminal (e.g., a cellular telephone) may be capable of receiving services from one or more networks. After the power is supplied, the terminal can search for a wireless miscellaneous: the wireless network is in range and the terminal can receive the wireless network from the wireless network. The wireless terminal can obtain the wireless network and test (10) the network. Register in.

The terminal may be within the coverage of zero or more wireless networks, and the zero or more wireless networks may or may not be in the preferred list. In this case, the terminal may be extended. Between cycles carried out

Search to find the best towel. If the terminal supports a radio technology and/or multiple frequency bands, the search can be more complicated because there can be more combinations of benefits and frequency bands for searching. During this search time, the user may not be able to initiate or receive services such as voice calls, emails, and short messages. Therefore, there is a need in the art to allow a terminal to reduce the technology used to acquire a wireless network, especially when the terminal is ignorant or ignorant of which networks are available.

Various aspects and features of the present disclosure are described in further detail below. [Embodiment] Figure 1 shows an example network environment 100 in which multiple wireless networks may be present. In this example, there are four wireless networks 110a, 110b, 110c, and 110d, and the four wireless networks are represented as networks A, B, C, and D, respectively. In general, each wireless network can have any coverage area and some or all of the coverage areas of the wireless network can overlap. In the example shown in Figure 1, wireless networks A, B&c are 119314.doc 1378734 stacked in area U4, which is shown in a cross-hatch. In general, each wireless network 110 can implement any radio technology such as Global System for Mobile Communications (GSM), Wideband Coded Multi-Directional Proximity (W-CDMA), Long Term Evolution (LTE), CDMA2000 IX, High Rate Packet Data (HRPD), IEEE 802.16, IEEE 802.20, IEEE 802.1 1, Hiperlan, Flash-OFDM, etc. f°GSM, W-CDMA, LTE, CDMA2000 1X, HRPD, and Flash-OFDM® are radios for WWAN technology. W-CDMA is part of the Universal Mobile Telecommunications System (UMTS). CDMA2000 1X and HRPD are part of cdma2000, also known as coded multidirectional proximity (CDMA). IEEE 8 02.16 and IEEE 802.20 are two series of standards for WMAN from the Institute of Electrical and Electronics Engineers (IEEE). IEEE 802.16 is commonly referred to as WiMAX. IEEE 802.11 is another series of standards from IEEE for WLAN and is commonly referred to as Wi-Fi. Hiperlan is another radio technology for WLAN. These various radio technologies are known to the art.

In general, a wireless network can implement one or more radio technologies. For simplicity, the following description assumes that each wireless network implements a radio technology, even though multiple wireless networks of different radio technologies may be assigned the same network identifier and/or may be a base station of a common group and/or This is also supported by other public network components. In an example for use in the following description, network 110a is a GSM network, network 110b is a UMTS network capable of implementing W-CDMA, and network 110c is a CDMA network capable of implementing CDMA2000 IX or HRPD 119314.doc 1378734 The network 110d is an IEEE 802.11 network. The IEEE 802.11 network can implement any of the IEEE 802.11 family of standards, such as 802.11a, 802.11b, 802.1 lg, 802.1 In, and the like. In the description of this article, ' "802.1 1" generally covers any of the standards in the IEEE 802.11 family of standards. • Multimode terminal 120 can be capable of wireless network communication with different radio technologies

• Letter. For example, the terminal can support GSM, W-CDMA, CDMA • IX, HRPD, 8〇 2.11, etc., or any combination thereof. Terminal 12A can be static or mobile and can also be referred to as a User Equipment (UE), a mobile station, an access terminal, a mobile device, a subscriber unit, a station, and the like. Terminal 120 can be a cellular telephone, a personal digital assistant (PDA), a wireless device, a wireless data modem, a handheld device, a laptop, a wireless telephone, and the like. Terminal 120 may be located in area 114 and may be capable of receiving GSM network u〇a, UMTS network 110b, and CDMA network 11〇Ce. However, terminal 120 may prefer to use UMTS as compared to gsm and cdma, for example, because River equipment • Better service and/or greater coverage. For terminal 120, there may be preferences for different network operators and their associated services. For example, a network 110a2 operator may be preferred to an operator of the network, and an operator of the network 11015 may be preferred to an operator of the network 110c. However, considering the radio technology and network operator bias (10) and (3) tender network appeal, terminal 12G may prefer UM = way 110b. Terminal 120 can therefore have a preferred list of preferred network operators and technology combinations. In general, the 119314.doc •10· 1378734 priority list can be formed based on network operator preferences, radio technology preferences 'network operators and radio technology preferences, and so on. Terminal 120 may be capable of receiving a local wireless network of different radio technologies at a particular location. However, for terminal 12G, all available networks may have only one or a few preferred network operators. Terminal 12 can perform a search to discover a better network operator and/or preferred radio technology. For the purpose of the search, terminal 120 can tune its receiver to use each frequency by the wireless network and determine if any wireless network is operating at the frequency. For each frequency, the terminal 12 can detect a signal from the wireless network at the frequency, obtain the timing and/or frequency of any detected signal, and demodulate the broadcast information from any acquired signal based on the broadcast. Information identifies the wireless network operator and decides whether to choose the wireless network. A network search for the radio technology can be performed in accordance with the procedures applicable to each radio technology. Terminal 120 may have a list of preferred network operators or a list of preferred network operators and technologies. The entities in the preferred list can be prioritized to ensure that the terminal 120 selects the home network operator when in range and selects to have a commercial configuration and/or home with the home network operator when roaming. The network operator provides advantages and/or some other network operations for the end user. Author. Terminal 120 can then perform a full search to identify all of the school network operators or all combinations of network operators and technologies available at the current location. Terminal 120 can then select the best network operator or combination of network operators and technologies for use. 、 , for example, when terminal 120 is energized at a new location (eg, after an airplane flight) or I lose coverage (eg, by long track) and needs to regain coverage at a different location 119314.doc location The terminal 120 may take a long time to pick up a better network. In many cases, the wireless network previously used by terminal 120 may be unavailable, and terminal 12 may be ignorant or ignorant of the network available at the new location. Terminal 120 can perform a full search to detect all available networks. During this full search, the user may not be able to call or receive any services. At the time of powering up or when the coverage is lost, the terminal 120 may search for a preferred network to receive services from a sub-optimal network or a non-preferred network that may be initially selected because a better network is unavailable at the previous location. Terminal 120 can also search for a better network. I hope to find a better network quickly in all of these situations. In one aspect, terminal 12 can store information about the cell and/or wireless network and can use the stored information to perform network selections more quickly and efficiently. Terminal 120 may store information about only the preferred network or about any available network or about the preferred network plus the available network or some other network combination if the preferred network is unavailable. In the following description, the recorded "network is a wireless network in which the terminal 12 has stored information about it, which is available for network selection. The recorded network may be a preferred or available network that may have been previously detected or accessed by terminal 120. In general, terminal 120 can store any type of information about a given network. For example, terminal 120 may store information for obtaining a network, such as a frequency band, a frequency channel, a radio technology, a scrambling code, and the like. The terminal 12 can also store information about the possibility of detecting the network, detecting the likelihood of the network, and the like. Terminal 120 may update the stored information when a new network is discovered and/or a new coverage of the recorded network 119314.doc -12- 1378734 area or capability is identified. The terminal 12 can be able to obtain a comprehensive database of cells and/or networks over time via self-learning capabilities. Terminal 120 may perform network selection at a particular time and may not be aware of which wireless networks are available, for example, because terminal 120 has been powered on at the new location. Terminal 120 can then search for a preferred network based on the stored information. For example, terminal 12 may prioritize the search for a preferred network operator or a combination of network operators and radio technologies. Terminal 120 can use the stored information to determine which frequency band(s) and radio technology are attempting to achieve a given preferred network. In a set of leaves, the terminal 12 can store usage information about the wireless network previously accessed by the terminal. Terminal 120 may store information regarding the extent to which each frequency band and radio technology used by each recorded network (e.g., aggregate access time) and/or other network usage statistics. Usage information can be used to determine which networks are typically available during a time period. A higher priority for a given network may indicate a greater likelihood of obtaining a network in the future. The terminal 120 can determine the search order based on the usage information and can search for one or more networks in the band and a radio technology having a higher priority. In another design, the terminal 12 can store past availability information about the network that was previously not accessed by the terminal. The terminal can store information about the percentage and/or number of times each network is detected and/or other availability statistics. Larger prioritized availability for a given network may indicate a greater likelihood of detecting the network in the future.

n93l4.dOC -13 - 1378734 In yet another design, the terminal 120 can store coverage information about the network previously detected by the terminal. The coverage information indicates where the terminal ι2〇 previously detected the network and can provide coverage information in a variety of formats. In the first mechanism, the coverage information may include a geographic description of the specific location at which each network is detected (eg, latitude and longitude coordinates terminal 120 may store an identification code such as each network, for each network The radio technology and frequency information, the geographical description of the location where each network is detected, etc. The terminal 120 can store network and coverage information about all locations that the terminal has accessed. Alternatively, the terminal 12 can Storing information about locations that may be spaced apart by at least some minimum distance (eg, at least one kilometer), which may reduce the amount of coverage information to be stored. Terminal 12 may omit locations where the terminal exists in a short period of time (eg, Information when the end user moves to further reduce storage. For the area where the terminal 12 is present during an extended period of time (eg, home, home neighbor, workplace, better shopping area, friends and relatives, etc. Etc., the terminal 12 can store information on the locations that can be closely spaced together on a more compact basis. The range information may include a geographical description of the visited coverage area (where each network has been previously detected by the terminal 120). The access area of the network is accessed by the terminal. Covering a portion of the area. This mechanism allows the terminal 12 to combine the coverage information about the network to reduce the storage space and the processing time for searching for stored information. The information about the coverage of the road may include access to the network. The position coordinates of the periphery of the coverage area. Alternatively, the terminal 12〇 may approximate the accessed coverage area by a geometry such as a circle, an ellipse, an η-edge, etc. For example, 119314.doc 14· 1378734 The approximated coverage area is approximated by a circle defined by the center and radius or (ii) an ellipse defined by the length of the center, the minor axis and the major axis, and the long axis orientation. The terminal 120 may select an appropriate geometry and/or based on the obtained The parameters of the selected geometry are determined with respect to the position coordinates of the network. The coverage information can also be given by other geographic shapes and formats. The coverage information for the recorded network is stored. The terminal 120 can store the coverage information and associate the detected network with the coverage information. For example, the terminal 12 can store different coverage areas (for example, geography). Shape) and a group of networks detected in each coverage area. The networks associated with a particular coverage area in the group may be given in a preferred order. Each time a different group of networks is detected in the area The road 120 can define a new coverage area. Alternatively, the terminal 120 can store a list of the detected networks and the list of coverage areas of each network. The one or more geographic shapes, a set of location coordinates, etc. can be used. The coverage area of each network is given. Terminal 1 can update the accessed coverage area of each network as needed. Terminal 120 can use the coverage information for the previously detected network to effectively perform network selection. . Terminal 12 can determine its current location based on any positioning method, such as using a separate positioning method independent of wireless network support, such as the Global Positioning System (GPS). For the first mechanism, terminal 120 can determine the closest previously visited location, where the stored information about the location of the network is available. The terminal 12 can retrieve the information about the network detected at the closest location and can search for such networks in a proper order so that the preferred network can be discovered as quickly as possible. For the second mechanism, terminal 120 may first determine its current location and then determine if the current bit 119314.doc is placed within the visited coverage area of any previously detected network. Terminal 120 can use the coverage that overlaps the current location to identify the network and can search for such networks in the desired order. Terminal 120 can also use information broadcast over the wireless network for network selection. For example, a base station (or access point) in a wireless network can broadcast its location coordinates. Terminal 120 can determine the location of such base stations based on the broadcast information. Terminal 120 can then determine its location based on the location of all received base stations and can identify the network available at that location based on the stored information. For example, if the terminal 120 may not or preferably obtain its location by other means due to cost or other reasons, the terminal 120 may also use the information broadcast by the base station to help store the detection at each location. Information about the network. Figure 2 shows the design of using the stored information to speed up network selection. Table 1 lists some of the types of information that can be stored by terminal 120 for each network and provides a short description of each type of information. Table 1 Information Type Description Network Preferences Indicates the preferences of the wireless network. Radio Technology Indicates the radio technology used by the wireless network. Frequency Information Indicates the frequency band and/or frequency channel used by the wireless network. Use information to indicate the priority or priority of the wireless network. Past Availability Information Indicates past availability of the wireless network. Coverage Information Indicates where the wireless network can be detected. Table 1 lists the different types of information that can be stored for each network. Different and/or other types of information can also be stored. For example, the terminal 120 can store only use information, only past availability information, coverage only information, 119314.doc • 16-1378734 use information and coverage information, and the like. The information in Table 1 can be maintained for a given network as follows. The network preference can be given based on the proportion of iKN, i is the best and N is the worst, where N can be any value. This preference can be defined by the home network operator and powered at the terminal. The frequency information may indicate one or more frequency bands used by the wireless network, one or more frequency channels, one or more broadcast channels, etc. and may be discovered when new bands and/or channels for the wireless network are discovered. The update terminal 120 can use radio technology and frequency information to search for a wireless network. The usage information indicates how often the wireless network was accessed in the past and can be updated whenever the wireless network is selected for use. Past availability information indicates that the wireless network has been in the past for a long time and can be updated every time the # wireless network is greeted. The overlay (4) can convey the visited coverage area of the wireless network and can be updated each time the terminal moves to a new area. Terminal 120 can maintain a table of stored information. In one design, the table may include - an entity for each _ wireless network previously detected or accessed by terminal 12(). When the terminal 12 discovers a new network, a new entity can be added to the table. Entities for each network may include fields for different types of information (e.g., information as shown in Table i). When collecting new information for each network, it can be updated for each field of the network. In yet another design, terminal 120 can store information about cells and networks previously taken by the terminal. The term "cell" can be used to refer to a base station (or access point) and/or its coverage area. The base station coverage area can be partitioned into multiple units that can be referred to as sectors or cell sectors. Small 2 domain. For the sake of simplicity, the following description assumes that the network is not sectorized 119314.doc 17 1378734 is the minimum coverage unit. The techniques described herein can also be used for sectorized networks. The 'sector or cell sector in the road is the smallest coverage unit.

3 shows an example network environment in which terminal 120 can be within the coverage of multiple cells in multiple wireless networks. In this example, the terminal 120 is within the coverage of the cells 310a and 310b in the UMTS network 110b, and is also within the coverage of the cell 3 l〇c in the CDMA network 1 l〇c. Cells 310a, 3 10b, and 3 10c are also represented as cells ^, B2, and ci, respectively, and are served by base stations 312a, 3121) and 312c, respectively. Cells B1, B2, and C1 overlap in region 314, which is shown in cross-hash in Figure 3.

Terminal 120 can store information about the cells detected at a particular location. Identification information about each cell can be obtained from transmission from a base station's access point, repeater, etc., and identification information about each cell can be associated with a base station, an access point, a repeater, etc. Transport association. The cell identification information can be global only-language and the cell identification information can be given in different formats for different (4) technologies. For example, the identification information about the similar or medium cell may include a Mobile Country Code (MCC), a Mobile Network Code (MNC), a Location Area Code (LAC), and a cell identification code. The identification information about the sector in (3) fiscal lx may include a system identification code (sid), a network identification code (NID), and a base m containing small uDs and sectors. The identification information about the sector in the HRPD may include a 128-bit subnetwork 1. The identification information about &# k u *' in the IEEE 802.11 network may include a media access control assigned to the access point and used to identify the coverage area of the access point.

119314.doc -18· 1378734 (MAC) address. The global unique identifier 0 of the cell can be broadcasted by the base station and/or the repeater serving each cell. Similarly, each access point can broadcast its MAC address in the beacon frame. Each time the terminal reaches the coverage of the base station or the repeater of the given cell, the terminal 120 can receive the global unique identification code of the cell. Whenever the terminal reaches the coverage of a given access point, the terminal can also receive the MAC address of the access point. The identification information about a given cell, sector or access point may also be referred to as a global cell identity code (G-ID).

The terminal 120 can also store about each detected cell ～6, r〇贝 each η*

For example, for each detected cell, if the cell identification information, the preference or priority of the wireless network or the combination of the network and the radio technology, the frequency information about the cell, the radio technology used by the cell, etc. If the network ID is not included or the network ID is not implied, the terminal 12 can store the network identifier (network ID) of the wireless network to which the cell belongs. If possible, the terminal can store information about each of the H-zones only once to reduce the amount of information to be stored about the cells detected at different locations. For each of the extracted cells, the terminal 12 can store information about other associated cells and/or networks in the cell's access coverage area that are also detected by the terminal 12A. The stored information may include information about each network, , , line technology and frequency information, network preferences or priorities, associated J-zone identification codes, and the like. Terminal 120 can also store signal strength information about the cell and/or network. For example, the terminal 120 may mark a cell having a weaker received signal strength, and/or a network having a weaker received cell. The mother cell is collected by the terminal or when the received signal I19314.doc •19, 1378734 with respect to the cell exceeds a certain threshold, 'can be collected at all or some locations on a continuous time basis or at discrete intervals And update information. A cell may have a normal coverage area in which the received signal strength of the cell is typically higher and the cell may be accessed to receive services from the associated networked path of the cell. The cell may also have an extended coverage area (e.g., an area surrounding the normal coverage area) in which the 'cell may be detected by terminal 120, but due to the lower signal strength' the cell may not be able to effectively serve the terminal. In correlating cells from different networks, terminal 12 may employ a normal coverage area and an extended coverage area for each cell to increase the number of other cells associated with the cell. In this case, the signal strength of the associated cell of a given cell may not always be higher and the signal strength of the associated cell may be consistently consistent throughout the normal coverage area or the entire extended coverage area of a given cell. Still or consistently low or can vary between low and high values at different locations. The signal strength information may also be stored for each cell associated with any given cell. Terminal 120 can also store the association between the signal strengths of the cells. For example, 'the location where the signal strength of the associated cell is higher (eg, in the normal coverage area of the associated cell) and the other location where the signal strength of the associated cell is lower respectively (eg, 'in the associated cell In the extended coverage area, the range of strength or signal strength for a given associated cell may be stored with respect to any cell. Terminal 120 may later detect a particular cell and obtain the signal strength of the cell at its current location. The terminal 12 can then determine which other cells and which of the other cells and such seeks have higher signal strength at the current location based on the cell identification code and signal strength. 119314.doc -20- 〆S) 1378734 And

Therefore it will be more likely to be available. Based on the preference of the value of the network associated with the cell associated with the cell having the higher signal strength, the terminal 12 may first attempt to obtain the 4 with the highest network preference, ask B 4 h, and the right is not obtained. Other cells may be attempted to be obtained according to the order of network preference. Whenever a given value is detected, 丨, F n electric μ. 疋J £, the stored information about the cell and/or the network can be connected so that the pass-through 120 can quickly identify the possible reception.

There are communities. For each cell (or access point), information for the cell and/or its network can be connected to other cells and/or networks that can also be received. This caution includes __^, 1 poor connection can also reduce the repetitive information about the cell and / or the network - in a specific location can be detected to the ^ network in the magic zone, then The terminal 120 may store the cell detected by the strongest debt, or, and the strongest cell, or all the tested cells and the & The storage process can be repeated each time a change is observed in the detected cell (eg, at another location).

Terminal 120 may reduce information storage by omitting cells that are (4) only for a short period of time. Terminals 12 may pass through an area when such cells are detected and are less likely to return to such cells for any significant amount of time. Terminal 120 may also record the cells discovered by extensive search. For example, the user can power up the terminal 12 when arriving at the airport and can perform an extensive search to retrieve the preferred network. The terminal 12 can store more information under this condition and can use this information to accelerate the network selection β, ^, 4: 4, and use the stored cell information for network selection when accessing the same airport next time. Terminal 120 may revisit or access the location where the cell was previously detected and information about the cells 119314.doc • 21 - is stored. The terminal 120 can detect the cell at the location, receive and decode the broadcast information from the detected cell, identify the detected cell based on the broadcast, and determine the stored information associated with the detected cell. Other cells and networks available (if any). The terminal then confirms the appropriate order of the wireless network indicated by the stored information as available at this location. The search order can be determined based on the preferences or priorities of the wireless network, as indicated by the stored information. The terminal 12 can then start searching for a wireless network simultaneously with the best network. For each wireless network, the terminal 120 can search for any cell in the network or a particular cell identified by the stored information. In the example shown in FIG. 3, the terminal 120 may first detect the cell B1 in the network B simultaneously in the area 314 and may be based on the connected cell B1 and the cell.

The cell B2&C1 in the networks B and c, which are also received at this location, are determined by the stored information. The terminal 12 can then determine the desired order of the search networks b and ^. Terminal 120 may first attempt to obtain network c and may search for any cell in network C (eg, 'using radio technology and frequency information stored with respect to network c') or a specific cell associated with the first detected cell 扪The C1 〇 terminal 谓 2 谓 can refer to a given cell at multiple locations, and can store information associated with a plurality of other cells and their networks at which the cell X / can be used. Terminal 120 may thereafter revisit one of these multiple locations and first measure cell X. Terminal 120 may then obtain a plurality of sets of cells associated with the first tested cell X to combine the groups and their networks, and search for the combined cells and/or networks in the desired order. Alternatively, terminal 12 can use 1193I4.doc -22- 1378734 with information about the signal strength of the associated cell (if previously stored) and search for the cell with the highest recorded signal strength. In yet another alternative method, terminal 120 can detect one of the cells associated with cell X (small cell). Terminal 120 can then obtain other cells associated with the second detected cell y and its network from the stored information. The terminal 12 can then first (ie only) search for a cell or network that is associated with the cell ^: less.

In general, the terminal 12 can initially detect any number of cells, determine other cells associated with each detected cell, and first (or only) search with all of the original (four) cells or a larger number of initial (4) The cell or network to which the cell is associated. If a plurality of small Hs are initially detected, the terminal 120 may combine information about the networks of all the detected cells to determine a smaller group or a larger, available network, wherein the available from the smaller group or the larger group Perform network selections over the network. The terminal 12G can obtain: (1) a larger group of networks based on the association of the networks associated with the initially guessed cells; or (1) a smaller group of networks based on such networks, Viteisecuon. Terminal 12〇 can also be based on other

The specific values of these drapes are for illustrative purposes only and may not correspond to any actual network.

For example, a single table may have an internal and external cell identification, a number, and an associated cell in another network. Each entity includes an external network identifier, a frequency band, and an internal identifier of the channel cell. . The single meter terminal 120 can be used as follows for the network and cell information in Table 2$+, Disaster Clothing 2 to Table 5

Network selection. The terminal 12A can be powered on and can first (iv) have a cell with a LAC_CI value of 25 96 among networks having an mcc mnc value of 200-49. The terminal 120 may scan any cell in the table associated with the cell with LA (the ci value is μ%. In this example, the terminal 12 may find that the LAC_CI value is used for the cell C3 in Table 5. The terminal 12 may Then verify whether the detected mccmnc value 200-49 matches the network to which the cell ci belongs (: 1^(::(3_河\(: value. In this example, Table 5 indicates that the cell phantom belongs to the network c) 'And Table 2 indicates that the network c has an MCC-MNC value of 200·49, and the MCC-MNC value matches the detected MCC-MNC value. The terminal 120 can thus confirm that the detected cell is indeed small.

It can be found from Table 5 that the two associated cells A3 and Β3 have overlapping coverage with the cell C3. By using Tables 2 and 5, terminal 120 can locate the cell 3, the virtual network, and can then determine its network preferences. In this example, the detected cell C3 belongs to the network c with preference 3, while the associated cells A3 and (1) belong to the network with preferences 1 and 2, respectively. Since network a has the highest preference, terminal 120 may attempt to detect cell A3 first. Tables 2 and 3 indicate that cell A3 is a GSM cell operating in the 19 〇〇 MHz band on channel 7〇0 and assigned a LAC-CI value of 230-122. Terminal 120 can use this information to quickly obtain cell A3 without the hassle of searching. If cell A3 is obtained, terminal (S) 119314.doc -26- 1378734 12〇 may attempt to access network a via this cell. If the cell illusion is not obtained, the terminal 120 may attempt to access the cell B3 in the network 3 having the second highest preference. If the cell & is not successfully obtained, the terminal 12 can fall back to the cell C3 originally detected in the network c. Terminal 12A can then know that there is no need to look for a heart based on the lack of other associated cells in cell 5 in Table 5. The π terminal 120 and/or other terminals may send to the network operator (for example, the service network operator) the terminals collected by using the self-learning technology and are suitable for the network selection.峪&Select information. For example, the terminal 12 can transmit information about cells and networks previously in different geographic regions or locations (4), cells and/or networks associated with the measured cells, detected cells, and networks. The identification code, the frequency used by the detected network, and radio technology. The terminal 12 can accumulate information in a certain period of time and: send the information as appropriate. Terminals 12 may also send lesser amounts of information more frequently, such as 'information about cells and networks that are being tested by terminal 120 at its current location. The terminal 12G can also send information when # and 1 as requested by the network operator. As a specific example, terminal 12 can send the information in Tables 2 through 5 to the network operator. The network operator can combine the information received from 2 different terminals in different locations to obtain more comprehensive information about the networks of the cells in the larger geographic area. The network operator can provide all the information of this comprehensive information to individual terminals to help network selection. s Network operators (for example, service or home network operators) are also available. The terminal 120 is used for information of network selection. The information provided may be similar to, or broader than, the accuracy and reliability of the information collected by the terminal 12 via self-learning I technology. 12 m m 吓 吓 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可The information provided may be related to the cells and/or networks available in different geographic areas or locations, f... Do not ask the community's associated small & and / or network, community and network identification code, the frequency of use of the network and radio technology. The information provided may be given in the above format (eg, as shown in Tables 2 through 5) or some other format. In one design, the network operator may provide information in the form of a Base Station Ephemeris (BSA) that can support other capabilities such as the location of the terminal 12. It usually includes information about the type of location and location services that are supported. For example, for every-whistle per-base = BSA, the geographic coordinates of the base station antenna for the cell may be provided, the frequency band of the cell, the frequency used for broadcast by the cell and/or other channels transmitted by the cell, and / or frequency hopping mechanism, transmission timing or W phase difference between other cells, cells in the same or other networks, and other cells in the cell. A broadcast channel can be obtained to obtain broadcast information for verifying the cell's identification code, for measuring the bit, and the like. The BSA may be modified and/or extended to include information for supporting network selection. The BSA may include information about cells (or base stations) available at different locations, associations between cells with overlapping coverage, identification codes and preferences of networks that help network selection, radio technologies and frequencies to assist in obtaining Information, information to support positioning, etc. The legs may also include information about other cells and/or networks that may be selected within the area covered by the cells included in the BSA. 119314.doc -28- 1378734 Each cell may broadcast ephemeris information that may be received and used by terminals within the coverage of the cell. The given cell may also send ephemeris information directly to the given terminal, for example, when and as requested by a given terminal. For example, ephemeris information may be provided to the terminal 12 by a network operator (e.g., a service or home network operator) and stored in the terminal 12 for future use. % covers all cells in all networks in a larger geographic area (for example, the entire country), and the ephemeris or other information used to help network selection can be more extensive. The amount of ephemeris information to be sent and subsequently stored can be reduced in various ways. In one design, the terminal 120 may only receive ephemeris information available to the terminal 120', e.g., receive star layer information only about the network utilizing the radio technology and frequency bands supported by the terminal 120. For example, the terminal 12 can support GSM and W-CDMA and can receive only the network using GSM and W-CDMA and is not related to the use of other radio technologies such as CDMA, IEEE 802.11, etc. News. In another design, ephemeris information may be provided regarding individual cells within a region geographically close to the terminal 12 且 and belonging to all or some of the networks having coverage in the region. In another example, ephemeris information about a group of cells (rather than individual cells) may be provided. For example, ephemeris information about a GSM location area that is well defined and identified as a small group may be provided. It is also possible to provide ephemeris information about many or all of the cells in a particular network (eg, when the private cell has the same or similar information) and the ephemeris information can include all of these small 119314.doc -29- Information on one of the supersets in 1378734. In yet another design, ephemeris information may be provided regarding a network (e.g., a preferred network) associated with a cell in a larger area (e.g., the entire country) and not associated with cells of other networks. Ephemeris information can include radio technologies supported by each network, frequency information for each network, and so on. Ephemeris information may also be reduced by providing only information about cells or clusters of coverage at locations where network selection is difficult (e.g., at the primary airport). The terminal 120 and/or other terminals may also transmit to the network operator information collected by such terminals and suitable for use as ephemeris information, such as the cell identification code, the frequency used, and the observed association. Timing or pilot phase difference between cells, and the like. The terminal 12 can collect information about the cell measured by the terminal in the time period (IV) and can transmit the collected information, for example, when it is convenient or requested. Terminal 120 may also only transmit (e.g., more frequently) information about the cell detected at its immediate location. The terminal can also send the location where it collects information (or the measurement used to determine its location). The road operator can use the information from the terminal 12G to obtain the location of the (4) cell. Network operators can also combine information received from different terminals to obtain more comprehensive ephemeris information and then provide the applicable portion to individual terminals to aid network selection. 4 shows a design of a process 400 performed by a terminal to perform network selection using coverage information.
