Description

Method for resident network, network system, network side equipment and user terminal

technical field

The present invention relates to the field of communication technology, and in particular to a method for residing in a network, a network system, network side equipment and a user terminal.

Background technique

In UMTS (Universal Mobile Telecommunications System), with the adoption of HSPA (High Speed Packet Access) technology, the rate of PS (packet switched) domain services has been greatly improved. In order to better meet the high-speed and diversified business needs of future users, and to smoothly evolve to the future long-term evolution LTE (longterm evolution) system, the 3rd Generation Partnership Project 3GPP standard organization has proposed HSPA+ (HSPA evolution) The main change is the flattening of the system structure, that is, in the HSPA+ network, there is no radio network controller RNC, and Node B+ (HSPA+ access point B) is directly connected to the core network as a node of the access network. Moreover, the Node B+ node can only be connected to the core network of the PS domain. For the support of circuit switched CS (circuit switched) service, the service must be provided by the RNC that supports both PS service and CS service before HSPA+ on the network.

The rate provided by the HSPA+ network will be higher. The user terminal UE corresponding to the HSPA+ network is called an R8 version UE, and the UE can support the high-speed data service provided by the HSPA+ network. Since the channel structure on the access side of the HSPA+ network basically remains the same as that of the HSPA network, UEs that support HSPA versions R6 and R7 can also be considered as UEs that can support high-speed data services. Therefore, R6 versions, R7 versions, UEs of the R8 version can be called high-capability UEs, and it is considered that these UEs are more likely to initiate high-speed data services. However, UEs before the R6 version, due to the limitation of access technology, can support a limited service rate. These UEs can be considered as low-capability UEs, and they are more likely to initiate CS services and low-rate PS services. Services can be well supported on traditional networks (legacy networks).

In the prior art of UMTS, the carrier frequency and access technology of the cell are distinguished when the UE camps on the network. The so-called camping is a set of actions in which the UE enters the idle state on a cell after cell selection and reselection, and can obtain normal services on the cell. As long as the cell is selected and reselected to a suitable cell, the UE can camp on to the community.

During the research and practice of the prior art, the inventor found the following problems in the prior art:

In the area where the HSPA+ network and legacy network are heavily covered, the existing cell selection and reselection only distinguish the carrier frequency and access technology of the cell, and do not distinguish between the high and low capabilities of the UE and the network, so that high-capability UEs may also camp Stay on the low-capability legacy network, and the low-capability UE may also camp on the high-capability HSPA+ network. This method of camping on the network cannot make good use of network resources.

Detailed ways

The embodiment of the present invention provides a method for camping on a network, which can optimize the camping of a user terminal UE on a network and make better use of network resources.

Please refer to FIG. 1, which is a flowchart of a method for residing on a network according to an embodiment of the present invention, including:

Step 101, sending the generated indication message to the user terminal;

The instruction message generated by the network side carries information describing network capabilities or carries information describing network capabilities and cell reselection parameter information, and is used to instruct the user terminal to select a network corresponding to terminal capabilities or services to camp on according to the instruction message. Of course, the indication message may also only carry cell reselection parameter information.

The information describing network capabilities may be information about supported networks or network-related versions, etc., including: information indicating support for traditional networks or information indicating support for high-speed packet access evolved HSPA+ networks, or information indicating support for LTE networks. The information supporting the HSPA+ network can be added in the IE (information element) of the UMTS system information block SIB (system information block). Correspondingly, the cell reselection parameter information corresponding to the HSPA+ network can also be set in the cell selection and reselection parameter set. The newly set cell reselection parameter information of the HSPA+ network may include the following setting methods, such as setting an offset value based on the cell offset of the original UMTS network, or directly resetting the cell offset for the HSPA+ network. Similarly, the information supporting the LTE network can also be added in the IE of the LTE system information block SIB. The cell reselection parameter information of the LTE network can also be set in the cell selection and reselection parameter set. When applying LTE, according to the concept of inter-frequency processing, a set of cell selection and reselection parameters can be defined for the legacy network and the HSPA+ network.

It should be noted that the instruction message generated by the network side may also carry HCS (Hierarchical Cell Structure) priority information, which is used to instruct the user terminal to select a cell with an appropriate priority according to its own capabilities or information such as initiated services. The network of the HCS resides. The network side assigns corresponding HCS priorities to the cells in the network. In the case of heavy coverage of HSPA+ and legacy networks, a high-priority HCS can be assigned to the HSPA+ network, so that high-capability UEs can preferentially camp on the HSPA+ network. ; In LTE, the layered structure of network re-coverage still exists, and the HCS priority of the cell can also be set according to the capabilities of the network and the services provided.

The network side may send the indication message to the user terminal UE by broadcasting or downlink signaling.

Step 102, the user terminal selects a network corresponding to the terminal capability or service to camp on according to the indication message.

The user terminal receives the indication message sent by the network side. If the indication message only carries the information describing the network capability, after the user terminal reads the information describing the network capability, according to the initiated service, its own terminal capability and the information describing the network capability, Select a network whose network capability corresponds to the terminal capability or service of the user terminal, and access to a cell of the corresponding network, receive broadcast information in the cell, and acquire cell reselection parameter information from the broadcast information to camp on. For example, a high-capability user terminal may choose to access a cell with a high-capability HSPA+ network according to its own terminal capability, and a low-capability user terminal may choose to access an HSPA+ network cell based on its own terminal capability. To a cell of a traditional network with a low network capability.

If the indication message carries information describing network capabilities and cell reselection parameter information, after reading the information describing network capabilities, the user terminal selects network capabilities and user The network corresponding to the terminal capability or service of the terminal, and access to the cell of the corresponding network, camps on according to the read cell reselection parameter information.

If the indication message only carries cell reselection parameter information, the user terminal can access the network to camp on according to the cell reselection parameter information.

It should be noted that when the indication message sent by the network side in step 101 carries HCS priority information, the user terminal selects the corresponding The network of the HCS with the appropriate priority is camped on.

In addition, the network side can also set that only user terminals that meet predetermined conditions can read the content of the indication message, and the predetermined conditions can be capability information of user terminals (such as terminal version information, category information, etc.) or initiated service information, etc. . For example, it is set that only user terminals of R6 version or above, or user terminals of class B, or user terminals whose service information is PS, can read the information indicating that they support the HSPA+ network. If a predetermined condition is set for the user terminal, the user terminal that satisfies the condition reads the cell reselection parameter information of the HSPA+ network, and applies it to the operation process of cell selection and reselection, and the specific process and current situation of cell selection and reselection The technical process is the same, except that at this time, the cell reselection parameter information of the newly set HSPA+ network is read. The category information of the user terminal refers to three categories of UE defined in LTE, namely category A, category B and category C. The maximum uplink and downlink rate requirements for Type A UEs can be: UL 50Mbps, DL 100Mbps, most suitable for camping on LTE networks; the maximum uplink and downlink rate requirements for Type B UEs can be: UL 25Mbps, DL 50Mbps, suitable for camping on LTE networks HSPA+ network; the maximum uplink and downlink rate requirements for class C UEs can be: UL 2Mbps, DL 2Mbps, suitable for residing on UMTS legacy networks. For class B, the priority of residing on the HSPA+ network is the highest, followed by classes A and C. This classification is only a specific example, and obviously other classification methods can also be used. Of course, the network side may not set conditions, and all UEs can obtain information describing network capabilities.

Please refer to FIG. 2, which is a flowchart of a method for residing on a network in Embodiment 2 of the present invention, including:

Step 201, the user terminal sends a message carrying information describing terminal capabilities or services to the network side;

For the scenario where the HSPA+ network and the legacy network have the same coverage, usually the network uses an additional routing area RA to identify the same coverage area. When the user terminal moves from the area covered by the traditional network (such as RA1) to the area covered by the HSPA+ network and the traditional network (such as RA2), it is found that the value of the RA identifier broadcast on the network is different from the value of the RA identifier saved in the UE. The user terminal initiates a routing area update process, and sends a routing area update request message to the network side, and the routing area update request message carries information such as capabilities or services of the user terminal. Of course, the UE may also use other uplink information to report information such as its capabilities or services.

Step 202, the network side sends the generated indication message to the user terminal;

The network side generates an indication message according to the information describing the terminal capability in the received message, and sends it to the user terminal, instructing the user terminal to camp on the designated cell, and the indication message carries the designated cell and/or parameter information of the designated cell.

After the user terminal sends a routing area update request message to the network side, the network side returns a routing area update response message to the user terminal, and the routing area update response message carries the specified cell and/or the parameter information of the specified cell, indicating that the user The terminal camps on the specified cell. For example, a user terminal moves from cell 2 of RA1, which is only covered by the traditional network, to cell 3 of area RA2, which is covered by the HSPA+ network and the traditional network. When the preferred service in the subscription information of the terminal is the packet service, the network side indicates the user terminal to cell 3 through the routing area update process according to the information describing the capability or service of the user terminal. Certainly, the network side may also use other downlink signaling to instruct the UE to camp on another cell.

Step 203, the user terminal selects a network corresponding to the terminal capability or service according to the indication message to camp on.

The user terminal receives the instruction message sent by the network side. If the instruction message carries the specified cell, the user terminal directly accesses the cell specified in the instruction message, obtains broadcast information in the cell, and resides in the cell according to the cell parameter information in the broadcast information. to the district.

If the indication message carries the parameter information of the specified cell, or the indication message carries both the specified cell and the parameter information of the specified cell, the user terminal camps on the cell according to the parameter information of the cell specified in the indication message.

Therefore, the technical solution of the embodiment of the present invention sends an indication message to the user terminal through the network side, so that the user terminal can choose an appropriate network to camp on according to its own capabilities and the capabilities of the network, so that a high-capability UE may camp on a high-capability UE. On the network, the low-capability UE camps on the low-capability network.

In the embodiment of the present invention, it is necessary to add information indicating that the HSPA+ network is supported, the information describes the network capability, and the cell reselection parameter information corresponding to the HSPA+ network is set. The specific implementation manners include but are not limited to the following manners.

method one:

1: Add information indicating support for HSPA+ network

In UMTS, the indication of whether the high-speed downlink packet access HSDPA and the enhanced dedicated channel E-DCH cell supports is set in the information element IE of SIB5 and SIB5 bis. In the embodiment of the present invention, an indication of whether the network side supports HSPA+ is added to the IEs of SIB5 and SIB5bis of the UMTS. The specific structure can be as follows but not limited to:

Cell IE type and parameters describe Version HSDPA cell Indicator (HSDPA cell indication) Enumerated(HSDPA CapableCell)(HSDPA Capable Cell) Rel-6 E-DCH cell Indicator (E-DCH cell indication) Enumerated(E-DCH CapableCell)(E-DCH Capable Cell) Rel-6 HSPA evolution cell indication (HSPA evolution cell indication) Enumerated(HSPA evolutionCapable Cell) (HSPA evolution capability cell) Rel-8

Table 1

The HSPA evolution cell indication (HSPA evolution cell indication) in Table 1 is a newly added IE, which is used to indicate that the HSPA+ network is supported. This IE can be read by all UEs, or only some UEs can read it. Specifically, the attributes of the user group that can read the IE can be set, such as high-capability UEs (UMTS UEs above R6 version), Or the UE whose service information is the PS service (especially the UE whose connection mode is CELL_PCH, URA_PCH or CELL_FACH state), the UE in the idle state can determine the service-related information according to the preferred service or the subscribed service.

2. Set the cell selection and reselection parameter information corresponding to the HSPA+ network

In the first way, the offset parameter of the cell reselection applied by the UMTS is modified. The network side modifies the cell selection and reselection parameter sets used by the UMTS network. The modified parameter sets are used for certain UE groups, such as for high-capability UE groups or UE groups for initiating high-speed PS services, so that other UEs You can not read the information, to achieve good backward compatibility.

For the modification in the UMTS network, it is to modify the cell selection and reselection parameter sets of the same frequency or different frequency (depending on whether HSPA+ is deployed in the same frequency network or different frequency network with the current system). See Table 2 and Table 3 for details. The so-called different frequency means that under the same access system, the carriers of the cells are different. Regarding the offset parameters for cell reselection, the offsets in Table 2 are mainly used for the adjustment of the cell itself, while the offsets in Table 3 are used for adjustments between the current serving cell and neighboring cells.

Cell IE type and parameters describe Version HSPA evolution cell indication (HSPA evolution cell indication) Enumerated(HSPA evolutionCapable Cell) (HSPA evolution capability cell) Rel-8 Cell individual offset (cell individual offset) Real(-10..10 by step of 0.5) (data range -10 to 10, step size 0.5) The default value is 0dB, which is used to adjust the measurement results Deltaoffset (the offset value of the individual offset of the cell) Real(-10..10 by step of 0.5) (data range -10 to 10, step size 0.5) The offset value added on the basis of the individual offset of the cell Rel-8

Table 2

In Table 2, HSPA evolution cell indication (HSPA evolution cell indication), Deltaoffset (offset value of individual cell offset) are newly added IEs for supporting HSPA+ network. The Cell individual offset of the existing original network is added to the Deltaoffset to obtain the cell offset of the HSPA+ network. This new IE can be read by all UEs, or only some UEs can read it. Specifically, the attribute of the user group that can read the IE can be set, such as a high-capability UE (a UMTS UE with R6 version or above) ), or a UE whose service information is a PS service (especially a UE in CELL_PCH, URA_PCH or CELL_FACH state), and a UE in an idle state can determine service-related information according to preferred services or contracted services.

Cell IE type and parameters describe Version Qoffset1 _{s, n} Integer(-50..50) (data range -50..50) Default value is 0.[dB] The default value is 0dB

Cell IE type and parameters describe Version Delta _Qoffset1 (Qoffset1 _{s, the offset value of the offset of n} ) Integer(-50..50) (data range -50..50) Used for HSPAevolution capability cell (cell used for HSPA evolution capability) Rel-8 Qoffset2 _{s, n} Integer(-50..50) (data range -50..50) Default value is 0.[dB] The default value is 0dB Delta _Qoffset2 (Qoffset2 _{s, the offset value of the offset of n} ) Integer(-50..50) (data range -50..50) Used for HSPAevolution capability cell (cell used for HSPA evolution capability) Rel-8

table 3

In Table 3, DeltaQoffset1 (Qoffset1s, the offset value of the offset value of n), DeltaQoffset2 (Qoffset2s, the offset value of the offset value of n) are newly added IEs for supporting the HSPA+ network. This IE can be read by all UEs, or only some UEs can read it. Specifically, the attributes of the user group that can read the IE can be set, such as high-capability UEs (UMTS UEs above R6 version), Or for UEs whose service information is PS services (especially UEs in CELL_PCH, URA_PCH or CELL_FACH state), UEs in idle state can determine service-related information according to preferred services or subscribed services.

Method two,

The main difference between method 2 and method 1 is that method 2 is to redefine the cell selection and reselection parameter set used in the HSPA+ network, which can be used directly, while method 1 is based on the cell selection and reselection parameters of the original UMTS network. Offset value, that is, add the set offset value to the cell selection and reselection parameters of the original UMTS network to obtain the cell selection and reselection parameters of the HSPA+ network.

1: Add information indicating support for HSPA+ network

The indication of whether the HSDPA and E-DCH cells are supported in UMTS is set in the information element IE of SIB5 and SIB5bis. In the embodiment of the present invention, an indication of whether the UE supports HSPA+ is added to the IEs of SIB5 and SIB5bis of the UMTS. The content of this part is the same as that in Method 1 and will not be described in detail.

2. Set the cell selection and reselection parameter information corresponding to the HSPA+ network

In the second method, the offset parameters of cell reselection applied by the HSPA+ network are defined. These parameters are used for certain UE groups, such as for high-capability UE groups or UE groups for initiating high-speed PS services, so that other UEs can This information is not read, for good backward compatibility.

Defining cell selection and reselection parameter sets in HSPA+ networks is equivalent to defining a set of cell selection and reselection parameter sets for HSPA+ networks in addition to cell selection and reselection parameter sets for intra-frequency, inter-frequency and inter-system systems. The so-called different systems refer to different access technologies, such as the Global System for Mobile Communications GSM, UMTS Terrestrial Radio Access Network UTRAN and LTE are different access systems. Regarding the offset parameters for cell reselection, the offsets in Table 4 are mainly used for the adjustment of the cell itself, while the offsets in Table 5 are used for adjustments between the current serving cell and neighboring cells.

Cell IE type and parameters describe Version HSPA evolution cell indication (HSPA evolution cell indication) Enumerated(HSPA evolutionCapable Cell) (HSPA evolution capability cell) Rel-8 Cell individual offset (cell individual offset) Real(-10..10 by step of 0.5) (data range -10 to 10, step size 0.5) The default value is 0dB, which is used to adjust the measurement results Cell individual offset for HSPA evolution (cell individual offset for HSPA evolution network) Real(-10..10 by step of 0.5) (data range -10 to 10, step size 0.5) Rel-8

table 5

HSPA evolution cell indication (HSPA evolution cell indication) in Table 4, Cell individualoffset for HSPA evolution (cell individual offset amount of HSPA evolution network) and Qoffset1s in Table 5, n for HSPA evolution cell (Qoffset1s of HSPA evolution network, n ), Qoffset2s, nfor HSPA evolution cell (Qoffset2s of HSPA evolution network, n) are newly added IEs for supporting HSPA+ networks. These newly-added IEs can be read by all UEs, or only some UEs can read. Specifically, the attributes of the user groups that can read the IEs can be set, such as high-capability UEs (UMTS versions above R6) UE), or UE whose service information is PS service (especially UE in CELL_PCH, URA_PCH or CELL_FACH state), and UE in idle state can determine service-related information according to preferred service or contract service.

What has been described above is the application environment where the UMTS system and the HSPA+ network are superimposed together, and another case is the application in LTE.

In LTE, the setting of cell selection and reselection parameters in this embodiment of the present invention is: for the same frequency, use a set of parameters; for different frequencies, use a set of parameters for each frequency; Ideas, different heterogeneous systems can each use a set of parameters.

When applied to LTE, because the services provided by the HSPA+ system and the legacy system are different, the requirements for resident requirements are also different. Therefore, a set of cell selection and reselection parameters can be defined for the legacy system and the HSPA+ system. The specific method You can refer to the process of redefining a set of cell selection and reselection parameter sets for the HSPA+ network in the second method above. The information supporting the LTE network can be added in the information element IE of the LTE system information block SIB. In this way, all UEs can select a suitable network according to their own terminal capabilities, and reside in the network.

For LTE cell reselection, the network side can also specify the attribute of the UE group that reads the HSPA+ network parameters, for example, according to the category of the UE. As mentioned above, three types of UEs can be defined in LTE, namely type A, type B and type C. The maximum uplink and downlink rate requirements for Type A UEs can be: UL 50Mbps, DL 100Mbps, most suitable for camping on LTE networks; the maximum uplink and downlink rate requirements for Type B UEs can be: UL 25Mbps, DL 50Mbps, suitable for camping on LTE networks HSPA+ network; the maximum uplink and downlink rate requirements for class C UEs can be: UL 2Mbps, DL 2Mbps, suitable for residing on UMTS legacy networks. For class B, the priority of residing on the HSPA+ network is the highest, followed by classes A and C. Of course, the attribute of the UE group that stipulates to read the HSPA+ network parameters can also be based on the version of the UE, for example, the version above R6, or the UE whose service-related information is high-speed PS.

Please refer to FIG. 3, which is a flowchart of a method for residing on a network according to Embodiment 3 of the present invention, including:

Step 301, sending the generated indication message carrying the home base station access information to the user terminal;

The instruction message generated by the network side carries home base station HNB (Home Node B) access information, and is used to instruct the user terminal to select the corresponding home base station network to camp on according to the instruction message.

The current standard proposes the research project of 3G/LTE Home NB. The basic idea is to set up a home base station HNB in the end user's home to provide low-cost, high-speed services for user terminals in the home environment. Therefore, the HNB and the operator's Node B (hereinafter referred to as the macro base station) also have overlapping coverage areas. Therefore, the network side can generate an indication message carrying the HNB access information to instruct the user terminal to select a corresponding HNB network to camp on according to the indication message.

HNB access information may include: user access information and/or HNB identification information, user access information may be completely public or only limited to certain users, specifically user mobile phone number, International Mobile Subscriber Identity IMSI, temporary Mobile Subscriber Number TMSI, Packet Switching Domain Temporary Mobile Subscriber Number P-TMSI, etc.

After the network side generates the indication message carrying the HNB access information, it can send the indication message to the user terminal UE through broadcast or downlink signaling.

Step 302, the user terminal selects the home base station network to camp on according to the indication message.

The user terminal preferentially selects the HNB network to camp on according to the HNB access information in the indication message. When the HNB where the user is located and the Node B of the operator have overlapping coverage areas, the advantage of the user terminal preferentially camping on the HNB network is that the service can be used through the HNB network, which can save costs and enjoy high-speed services. The service experience of the user is improved, and the load of the macro cell can also be shared.

In addition, because the user terminal is basically in a relatively static state when it is in the home environment, it is also possible to set the HCS parameter of the HNB network to a high priority, and carry the HCS priority information in the indication message sent by the network side to the user terminal, In this way, the user terminal in the home environment preferentially chooses to camp on the HNB network according to the HCS priority information carried in the indication message, so as to realize optimization of cell reselection.

The foregoing describes in detail the method for residing on a network according to the embodiment of the present invention. Correspondingly, the embodiment of the present invention provides a network system.

The parameter information of the cell generated by the generating unit 401 includes: cell reselection parameter information of a traditional network or cell reselection parameter information of a high-speed packet access evolved HSPA+ network, or cell reselection parameter information of a long-term evolution LTE network; wherein, the The cell reselection parameter information of the HSPA+ network is to set an offset value based on the cell offset of the original network, or directly set the cell offset for the HSPA+ network. Set the cell offset for the HSPA+ network, that is, redefine the cell selection and reselection parameter set for the HSPA+ network, and the defined cell reselection parameters can be used directly. Set the cell offset value for the HSPA+ network, that is, set the offset value on the basis of the cell reselection parameters of the original UMTS network, then add the set offset value to the cell reselection parameters of the original UMTS network to obtain the cell reselection value of the HSPA+ network Select parameters.
