Embodiment
The embodiment of the invention provides a kind of method of residing network, can optimize user terminal UE resident on network, more the good utilisation Internet resources.
Seeing also Fig. 1, is the flow chart of the method for the embodiment of the invention one residing network, comprising:
Step 101, the Indication message that send to generate to user terminal;
The Indication message that network side generates carries the information of describing network capabilities or carries information and the cell reselection parameters information of describing network capabilities, is used for indicating user terminal and selects counterpart terminal ability or professional network to carry out resident by Indication message.Certainly, Indication message also may be only to carry cell reselection parameters information.
The information of described description network capabilities can be the network of support or the information of network related versions etc., comprising: express support for the information of legacy network or express support for the information that high-speed packet inserts evolution HSPA+ network, or express support for the information of LTE network.Support the information of HSPA+ network in the cell IE (information element) of the System information block SIB of UMTS (system information block), to increase.Accordingly, the cell reselection parameters information of corresponding HSPA+ network also can be concentrated in cell selecting and reselecting parameters and be provided with.The cell reselection parameters information of newly-installed HSPA+ network can comprise following several set-up mode, and for example the sub-district amount of bias based on former UMTS network is provided with bias, or directly is HSPA+ network of Central Monitoring Room sub-district amount of bias.In like manner, the information of supporting the LTE network also can increase in the cell IE of the System information block SIB of LTE.The cell reselection parameters information of LTE network also can be concentrated in cell selecting and reselecting parameters and be provided with, and when using LTE, according to the thinking that alien frequencies is handled, can be each a self-defined cover cell selecting and reselecting parameters of legacy network and HSPA+ network.
Need to prove, the Indication message that network side generates also can carry layered cell structure HCS (Hierarchical Cell Structure) precedence information, is used for indicating user terminal and selects the network of the HCS of corresponding proper priority to carry out resident according to the ability of oneself or the information such as business of initiation.Network side is the priority of the corresponding HCS of cell allocation in the network, under the situation about heavily covering for HSPA+ and legacy network, can be the HCS of a high priority of HSPA+ network allocation, makes high ability UE can preferentially reside on the HSPA+ network; And in LTE, the hierarchy that network heavily covers still exists, and the HCS priority of sub-district also can be provided according to the ability of network and the business that provides.
Network side can send to user terminal UE by broadcasting or downlink signaling mode with Indication message.
Step 102, user terminal select counterpart terminal ability or professional network to carry out resident by described Indication message.
User terminal receives the Indication message that network side sends, if Indication message only carries the information of describing network capabilities, after user terminal reads the information of described description network capabilities, information according to the business of initiating, the terminal capability of self and description network capabilities, select the terminal capability or the corresponding network of business of network capabilities and user terminal, and be linked into the sub-district of corresponding network, at this sub-district receiving broadcasting information, from broadcast message, obtain cell reselection parameters information and carry out resident.For example, the user terminal of high ability can be high ability according to self terminal capability, then select to be linked into the sub-district that network capabilities is the HSPA+ network of high ability, the user terminal of low ability can be low ability according to self terminal capability, then selects to be linked into the sub-district of network capabilities for the legacy network of low ability.
If Indication message carries information and the cell reselection parameters information of describing network capabilities, after user terminal reads the information of described description network capabilities, information according to the business of initiating, the terminal capability of self and description network capabilities, select the terminal capability or the corresponding network of business of network capabilities and user terminal, and be linked into the sub-district of corresponding network, undertaken resident by the cell reselection parameters information that reads.
If Indication message only carries cell reselection parameters information, user terminal can be linked into network according to cell reselection parameters information and carried out resident this moment.
Need to prove, the Indication message that sends when network side in the step 101 is when carrying the HCS precedence information, user terminal is according to the HCS precedence information that carries in the Indication message, and selects the network of the HCS of corresponding proper priority to carry out resident according to the ability of oneself and the information such as business of initiation.
In addition, network side can also be set the content that the user terminal that conforms to a predetermined condition just can read Indication message, and described predetermined condition can be for the ability information (for example terminal versions information, classification information etc.) of user terminal or for the business information initiated etc.For example setting the user terminal have only the R6 version above, perhaps is the user terminal of category-B, and perhaps business information is that the user terminal of PS just can read the information that expresses support for the HSPA+ network.If user terminal is provided with predetermined condition, the user terminal that then satisfies condition reads the cell reselection parameters information of HSPA+ network, be applied to the operating process that it carries out cell selecting and gravity treatment, it is the same specifically carrying out the process of cell selecting and gravity treatment and the process of prior art, and what just adopted this moment is the cell reselection parameters information that reads newly-installed HSPA+ network.The classification information of user terminal is meant the classification that has defined three kinds of UE in LTE, is respectively category-A, category-B and C class.The requirement of the highest up-downgoing speed of category-A UE can be: UL 50Mbps, and DL 100Mbps, the most suitable resident to the LTE network; The requirement of the highest up-downgoing speed of category-B UE can be: UL 25Mbps, and DL 50Mbps is fit to resident to the HSPA+ network; The requirement of the highest up-downgoing speed of C class UE can be: UL 2Mbps, DL 2Mbps is fit to resident legacy network to UMTS.For category-B, the priority of its resident HSPA+ network is the highest, and A, C class are taken second place.This classification is a specific embodiment just, obviously also can adopt other mode classifications.Certainly, network side can not impose a condition yet, and all UE can both obtain the information of describing network capabilities.
Seeing also Fig. 2, is the flow chart of the method for the embodiment of the invention two residing network, comprising:
Step 201, user terminal send the message of carrying the information of describing terminal capability or business to network side;
With the scene that covers, network can use an other Routing Area RA to identify this with the zone that covers usually for HSPA+ network and legacy network.When user terminal moves to HSPA+ network and legacy network with the zone (for example RA2) that covers from the zone (for example RA1) that the legacy network list covers, find that the RA that broadcasts on the network identifies the value difference with the RA sign of preserving among the UE, this moment, user terminal was initiated the routing region updating flow process, send the routing region updating request message to network side, carry information such as the ability of user terminal or business in the described routing region updating request message.Certainly, UE also can use other uplink information to report information such as its ability or business.
Step 202, network side send the Indication message that generates to user terminal;
Network side generates Indication message according to receiving the information of describing terminal capability in the message, and sends to user terminal, and indicating user terminal is resident to designated cell, carries the parameter information of the sub-district of the sub-district of appointment and/or appointment in the described Indication message.
When user terminal after network side sends the routing region updating request message, network side returns the routing region updating response message to user terminal, carry the parameter information of the sub-district of the sub-district of appointment and/or appointment in the described routing region updating response message, indicating user terminal is resident to designated cell.For example user terminal moves to the sub-district 3 of HSPA+ network and the same region R A2 that covers of legacy network from the sub-district 2 of the RA1 of legacy network list covering, this sub-district 3 is to belong to the HSPA+ network, user terminal is when supporting preferred business in the CAMEL-Subscription-Information of the user terminal of high-rate packets business or user terminal to be Packet Service, network side is described ability of user terminal or professional information according to these, by the routing region updating flow process user terminal is indicated to sub-district 3.Certainly, it is resident to other sub-district that network side also can use other downlink signaling indication UE.
Step 203, user terminal select counterpart terminal ability or professional network to carry out resident by described Indication message.
User terminal receives the Indication message that network side sends, if carry the sub-district of appointment in the Indication message, then user terminal directly is linked into the sub-district of appointment in the Indication message, obtains broadcast message in this sub-district, and is resident to this sub-district by the cell parameter information in the broadcast message.
If carry the parameter information of the sub-district of appointment in the Indication message, perhaps carry the parameter information of the sub-district of the sub-district of appointment and appointment in the Indication message simultaneously, it is resident to this sub-district that then user terminal is pressed the parameter information of the sub-district of appointment in the Indication message.
Therefore, the technical scheme of the embodiment of the invention sends Indication message by network side to user terminal, make user terminal select suitable network resident according to the ability of self-ability and network, like this can be so that the UE of high energy power may residently go to high ability network, low ability UE is resident to low ability network.

Above-mentioned introduction be the applied environment that UMTS system and HSPA+ network are superimposed, also having a kind of situation is application in LTE.
In LTE, the embodiment of the invention to the setting of cell selecting and reselecting parameters is: for frequently, use set of parameter; For alien frequencies, each frequency is used set of parameter; The situation of different system, according to the thinking that alien frequencies is handled, different different systems can use set of parameter separately.
When being applied to LTE, because it is professional different that HSPA+ system and legacy system provide, so on resident demand, require also different, so can be legacy system and each a self-defined cover cell selecting and reselecting parameters of HSPA+ system, concrete grammar can be used for the cell selecting of HSPA+ network and the process of reselecting parameters collection with reference to defining a cover again at the HSPA+ network in the aforesaid way two.The information of supporting the LTE network then can increase in the cell IE of the System information block SIB of LTE.Like this, all UE can select suitable network according to the terminal capability of oneself, and resident in this network.
For the sub-district gravity treatment of LTE, network side can stipulate to read the attribute of the UE group of HSPA+ network parameter equally, for example according to the classification setting of UE.As previously mentioned, can define the classification of three kinds of UE among the LTE, be respectively category-A, category-B and C class.The requirement of the highest up-downgoing speed of category-A UE can be: UL 50Mbps, and DL 100Mbps, the most suitable resident to the LTE network; The requirement of the highest up-downgoing speed of category-B UE can be: UL 25Mbps, and DL 50Mbps is fit to resident to the HSPA+ network; The requirement of the highest up-downgoing speed of C class UE can be: UL 2Mbps, DL 2Mbps is fit to resident legacy network to UMTS.For category-B, the priority of its resident HSPA+ network is the highest, and A, C class are taken second place.Certainly, regulation reads the attribute of the UE group of HSPA+ network parameter also can be based on the version of UE, and for example more than the R6 version, or service related information is the UE of high speed PS etc.
Seeing also Fig. 3, is the flow chart of the method for the embodiment of the invention three residing network, comprising:
The Indication message that network side generates carries Home eNodeB HNB (Home Node B) access information, and being used for indicating user terminal, to select corresponding home base station network to carry out by Indication message resident.
Proposed the research project of 3G/LTE Home NB in the present standard, its basic thought is at terminal use's family one family base station HNB to be set, and the business of low expense, two-forty is provided for the user terminal under the home environment.So it is overlapping covered that the Node B of HNB and operator (below be called macro base station) also exists.Therefore network side can generate the Indication message that carries the HNB access information, is used for indicating user terminal and selects corresponding HNB network to carry out resident by Indication message.
The HNB access information can comprise: user's access information and/or HNB identification information, user's access information can be full disclosure or only limit the use to the certain user, specifically can be subscriber phone number, international mobile subscriber identity IMSI, temporarily moved subscriber number TMSI, packet switch domain temporarily moved subscriber number P-TMSI etc.
After network side generates and carries the Indication message of HNB access information, Indication message can be sent to user terminal UE by broadcasting or downlink signaling mode.
It is resident that user terminal preferentially selects the HNB network to carry out according to the HNB access information in the described Indication message.When the Node B of HNB that the user was positioned at and operator exists when overlapping covered, the preferential resident benefit to the HNB network of user terminal is: just can use business by the HNB network, can cost saving, enjoy the service of two-forty, so just improved user's business impression, and the load that can share macrocell.
In addition, because when user terminal is in the home environment, basically be in relative static conditions, therefore also can be arranged to high priority to the HCS parameter of HNB network, in sending to the Indication message of user terminal, network side carries the HCS precedence information, user terminal in the home environment is just according to the preferential resident HNB network that arrives, the realization optimizing cell reselection selected of the HCS precedence information that carries in the Indication message like this.
Foregoing describes the method for embodiment of the invention residing network in detail, and corresponding, the embodiment of the invention provides a kind of network system.
