Description
Technical Field
The invention relates to the technical field of communication, in particular to a search and measurement technology of closed subscriber group cells.
Background
A CSG (Closed Subscriber Group) is a small network covering a limited area, serving a specific Group of subscribers, and is called a Closed Subscriber Group. Such a network is accessible only to users belonging to the group, and users outside the group are not allowed access. Meanwhile, there is a class of CSG, which can serve all users, such as CSG in airport, station, etc., and only cover a small area, but allow all users at the location to access.
At present, in a connectionless state between a terminal and a network, the network calls the terminal by paging. If the terminal moves among different cells, the network realizes the connection to the terminal through cell reselection. In a connected state between a terminal and a network, that is, the terminal and the network have data transmission, generally, the terminal reads a CSG system message to interrupt current data transmission, and generally, to reduce the influence on data services, the terminal is limited to read an interval of the CSG system message.
Therefore, when the terminal needs to access the network, the terminal searches the CSG cell only in the vicinity of the CSG, and searches other areas with low frequency or does not search at all. Meanwhile, when only one CSG allows access to users in a group, access to users in a non-group will fail, so that the terminal reads an ID (closed subscriber group identifier) of the CSG from a system message of the CSG cell before access, matches the read ID of the CSG with a CSG ID list stored in the terminal itself, and determines whether the terminal can access to the current cell. When the terminal is not in the vicinity of the accessible CSG cell, the terminal can continuously read the system messages of other CSG cells.
In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art: when a connection is established between a terminal and a network or cell reselection or handover is performed, the existing positioning technology is adopted to perform one-to-one detection positioning on surrounding cells, and the system information of the surrounding CSG cells is read to further search and determine the CSG cells suitable for the terminal to access. Thus, it takes a long time for the terminal to perform cell reselection or handover to an appropriate CSG cell. And in the process of searching for a proper CSG cell, the terminal needs to continuously read system messages of other CSG cells, so that the power consumption of the terminal is increased.
Meanwhile, since the frequency of reading system messages by the terminal in the connected state is very low, once a suitable cell is found, measurement reporting must be performed immediately, and handover is started, so that the terminal is not easy to handover to the cell with the best signal, but only the first suitable cell to be found, and since the cells under the same frequency in the UMTS and LTE systems interfere with each other, the method is obviously not suitable.

Detailed Description
In order to solve the problem that a terminal needs a long time to perform cell reselection or handover to a suitable public CSG cell in the prior art, embodiments of the present invention provide a method and an apparatus for searching and measuring a closed subscriber group cell, and the present invention is described in detail below with reference to the accompanying drawings and embodiments.
As shown in fig. 1, a method for searching and measuring a closed subscriber group cell according to an embodiment of the present invention is provided; the method comprises the following steps:
101: acquiring physical layer cell identification group information of a closed subscriber group cell; the physical layer cell identification group information of the closed user group cell is divided according to different service characteristics. The PCI group information obtained by the terminal and divided according to different service characteristics may be sent to the terminal through a system message broadcast/dedicated signaling of the network, or may be configured in advance at the network system side and the terminal. The adoption of the configuration method can simplify the flow, and the adoption of the network system side transmission method can make the mechanism more flexible and can accept dynamic changes. The specific implementation flow of the step is as follows:
classifying the closed user group cell and all physical layer cell identifications belonging to the closed user group cell according to service characteristics;
and distributing physical layer cell identification group information corresponding to the cell type of the closed user group cell according to the cell type of the closed user group cell.
The following describes the division of the physical layer cell identification group information of the closed subscriber group cell in detail by taking a public PCI and a private PCI as examples;
for a user such as a specific home, an enterprise, etc., the CSG is a closed cell, which can only be used by employees in the home or the enterprise, and thus can be regarded as a private cell; and public places such as airports can allow access of ordinary passengers, which is equivalent to a public CSG cell. According to the difference between public and private, the PCI reserved for the CSG cell may be divided as shown in fig. 10:
one part of the private PCI is used for a private cell; the other part is a public PCI used for the public cell, when the number of the PCIs is limited, a part of shared parts can be arranged between the two, and the ranges of the two are not overlapped.
For example: after the CSG cell is powered on, the network system side respectively selects PCI of different categories according to whether the network system side is a public CSG, and if the network system side does not have the shared PCI, the PCI can be respectively selected in a Private PCI and a public Common; if there is shared PCI, then preferentially selecting PCI of non-shared part, only if PCI of non-shared part is not enough, then selecting PCI of shared part; the non-public CSG cell must not select the PCI of the public cell and vice versa.
In fact, even in a public occasion such as an airport, all users may not access the CSG cell, but only a VIP user can access the CSG cell, and in this case, the CSG cell of the airport is equivalent to a semi-public service cell, and access is allowed only to users with special identities. Therefore, the above-mentioned division method can be divided into private PCI/semi-public PCI/public PCI, etc.
It should be noted that the following embodiments all take private/public PCI classification as an example, and other classification methods are also applicable to the present invention, and are not described herein again.
102: and searching and measuring the closed user group cell by the terminal according to the physical layer cell identification group information of the closed user group cell.
It should be noted that after the step 102 is executed, the method may further include:
measuring and ranking the signal strength of the closed subscriber group cells;
selecting the closed user group cell with the strongest signal;
and accessing the terminal to the closed user group cell with the strongest signal according to the read system message.
As shown in fig. 2, a specific implementation flow of step 102 according to the embodiment of the present invention is shown; the method further comprises the following steps:
201: judging whether the terminal meets the conditions for searching and measuring the private CSG cell; determining whether the terminal currently meets the condition of searching a private CSG cell or not according to fingerprint information of the terminal;
202: if the terminal meets the conditions of searching and measuring the private CSG cell, the terminal measures and/or reports the measurement to the public cell and the private cell; the terminal can simultaneously measure and/or report the measurement to the public cell and the private cell; or the terminal preferentially measures and/or reports the measurement to the private cell; or the terminal measures and/or reports the private cell at a higher frequency and measures and/or reports the public cell at a lower frequency.
203: and if the terminal does not meet the conditions for searching and measuring the private CSG cell, the terminal measures and/or reports the searched public cell. The terminal can only measure and/or report the searched public closed subscriber group cell, but not measure the searched private closed subscriber group cell; or the terminal measures and/or reports the searched public closed user group cell at a higher frequency and measures the searched private closed user group cell at a lower frequency.
The above finger print information is locally counted and stored by the terminal, and the finger print information may be information of a macro cell adjacent to a CSG cell allowed to be accessed, or may be information of a CSG geographic location, and the terminal may locate the current location by means of a GPS or the like, or may be other related information. And when the triggering condition indicated by the finger print information is met, the terminal initiates searching, measuring and measuring reporting of the CSG cell.
As shown in fig. 3, a further detailed implementation flow of the step 102 according to the embodiment of the present invention is shown; after judging that the terminal currently meets the conditions for searching and measuring the private CSG cell, the method further comprises the following steps:
301: judging whether the closed user group cell is a closed user group cell which is locally stored by the terminal and can be successfully reselected or not according to the information of the closed user group cell which is locally stored by the terminal and is successfully reselected; namely, the terminal can store the cell information of successful access locally; wherein the successfully reselected closed subscriber group cell information at least comprises: the frequency point of the closed user group cell, the identification information of the physical layer cell and the identification of the closed user group cell.
302: if the searched closed user group cell is a locally stored closed user group cell which can be successfully reselected, the terminal measures and/or reports the locally stored closed user group cell which can be successfully reselected with a higher frequency;
it should be noted that this step may further include:
the terminal reads system information to obtain a closed user group identifier;
judging whether the acquired closed user group identification allows the closed user group cell to be accessed;
if the network allows the terminal to access, the terminal accesses the network;
and if the network does not allow the terminal to access, the terminal measures and/or reports the measurement to all the closed user group cells, reads the system information and updates the locally stored information.
303: and if the searched closed user group cell is not the closed user group cell which is locally stored and can be successfully reselected, the terminal measures and/or reports the closed user group cell with lower frequency.

402: and if the accessed closed user group cell is not recorded in a table of an accessible closed user group cell identification column locally stored by the terminal, triggering the terminal to search and measure the closed user group cell.
