Description
Technical field
The present invention relates to mobile communication technology, particularly the paging technique of subscriber equipment in the Long Term Evolution (Long Term Evolution is called for short " LTE ").
Background technology
Mobile communication technology entered since the second generation mobile communication (The Second Generation is called for short " 2G ") from 20 end of the centurys, had obtained developing rapidly.But along with the increase of number of users, and to the improving constantly of requirements such as class of business and performance, 2G demonstrates the restriction at aspects such as data transmission capabilities gradually.Therefore, the 3G (Third Generation) Moblie that data transmission capabilities is stronger (The Third Generation, be called for short " 3G ") has entered the high speed development stage, and moving communicating field presents by 2G progressively to the situation of 3G transition.
When the 3G system progressively entered commercialization, industry had begun Research on New work.The company that has is called super 3G (Super 3G) technology with these new technologies, and the company that also has is referred to as the 3.9G technology.3.9G the data traffic transmission speed of technology will reach about 100Mbps, and introduce a large amount of advanced technologies, as OFDM (Orthogonal Frequency Division Multiplexing, be called for short " OFDM ") and multiple-input and multiple-output (Multiple Input Multiple Output, be called for short " MIMO ") etc., unification is called the evolved technology of 3G with these advanced technologies in China, also is the E3G technology.
In order to realize the standardization of E3G technology, since the end of the year in 2004, third generation partner program (3rd Generation Partnership Project is called for short " 3GPP ") and 3GPP2 successively began corresponding research work.
Along with high speed downlink packet inserts (High Speed Downlink Packet Access, be called for short " HSDPA "), the introducing of enhanced uplink enhancement techniques such as (Enhanced Uplink), the 3GPP wireless access technology is that very high competitiveness is arranged in a few years from now on.Yet in order to guarantee the competitiveness of more longer time (as 10 years or longer), 3GPP started Long Term Evolution (Long Term Evolution is called for short " LTE ") project since the second half year in 2004.
In the content of the discussions of normal structure for the LTE network, the state that a very important content is exactly an agreement is divided.At present according to UE in moving process employed resource situation and with the degree of contact of network side, with subscriber equipment (User Equipment, abbreviation " UE ") is divided into three states, promptly divide amorph (LTE_detached), Idle state (LTE_idle) and activated state (LTE_active), correspond respectively to existing Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, abbreviation " WCDMA ") three similar states in the network: divide amorph, Idle state and connected state (connected), the activated state in the LTE network are the connected state in the WCDMA network.
When UE was in the branch amorph, UE no longer got in touch to some extent with network, as UE shutdown or situation such as stop using.When UE is in Idle state, can in a very big zone, roam, and needn't register, and network side is not preserved the information of UE to the base-station node (NodeB) in the sub-district of roaming.When UE uses certain professional or during in talking state, be in connected state.
When UE was called, network side need be located called UE by this technological means of paging, when network side is sought certain UE at needs, issues corresponding beep-page message, and UE will set up the communication with network side after receiving the beep-page message of issuing oneself, as shown in Figure 1.
In the LTE network, according to the difference of the residing state of UE, network will issue dissimilar beep-page messages when seeking UE.For the UE that is under the Idle state, because it changes Serving cell by the mode of cell selecting and gravity treatment in moving process, network only knows which this UE is in and follows the tracks of territory (TA), therefore beep-page message issues towards whole tracking territory, and for the UE that is in connected state, because it changes Serving cell by the mode of switching, the residing accurate location of this UE, as in which sub-district, be as can be known for network, so beep-page message issue towards single subdistrict.
In actual applications, there is following problem in such scheme: for the UE that is under the activated state, network side still might can't position it.
Cause the main cause of this situation to be, because when UE is in activated state, in order to save the UE power consumption, and it is mutual to reduce space interface signaling, there is not transfer of data when UE a period of time, when perhaps being in the state of discontinuous reception/transmission for a long time, network side will think that UE is in economize on electricity or semi-static pattern, at this moment, if UE moves to another sub-district from a sub-district, will change Serving cell by the mode of sub-district gravity treatment, and not notify the change (for power saving) of its Serving cell of network side, therefore when network side need be when this UE sends beep-page message, possibly can't positioning this UE by the beep-page message of service-oriented sub-district.
Summary of the invention
In view of this, main purpose of the present invention is to provide the paging method and the system thereof of subscriber equipment in a kind of long-term evolving network, makes and can accurately find the UE that is under the state of activation by paging in LTE.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core of the present invention is, when network side need be when the UE that is in activated state sends beep-page message, the rrc layer of network side earlier by with the primitives interoperation of the MAC layer of network side, inquire about whether this UE is under the activated state but be not energy-saving mode of informing network side all when at every turn carrying out the sub-district gravity treatment, if, then this rrc layer sends this beep-page message to the predeterminable area bigger than the Serving cell scope of this UE, otherwise this rrc layer sends this beep-page message to the Serving cell of this UE.
Energy-saving mode can be described as semi-static pattern or sleep pattern again, mainly be provided with for the consideration of saving UE electric energy and Internet resources, under energy-saving mode, UE can use discontinuous emission (Discontinuous Transmission, be called for short " DTX ") and discontinuous reception (DiscontinuousReception, abbreviation " DRX ") mode is worked, do not report location update message during sub-district gravity treatment at least in one case to network side, for example, can stipulate if new sub-district and original sub-district just do not report location update message in a NodeB.
More than principle of the present invention has been carried out brief description, below according to this principle, first execution mode of the present invention is described in detail.
The paging method of UE as shown in Figure 2 among the first execution mode LTE of the present invention.
In step 210, network side need be judged the state of this UE when UE sends beep-page message.Specifically because when UE is in different states, as Idle state, when dividing amorph or activated state, network side need to this UE transmission towards different range beep-page message.Therefore, when network side need be when UE sends beep-page message, the rrc layer of network side need be judged the present residing state of this UE earlier.If this UE is in idle condition, then enter step 220; If this UE is in released state, then enter step 230; If this UE is in state of activation, then enter step 240.
When UE is in idle condition, enter in the step 220, network side sends towards the beep-page message of following the tracks of the territory to this UE.
When UE is in released state, enter in the step 230, network side returns paging failure message to its upper strata.
When UE is in state of activation, enter in the step 240, the rrc layer of network side is inquired about this UE to the MAC layer and whether is in energy-saving mode.
Specifically, for the UE that is under the state of activation, when meeting some requirements or criterion, such as, in the regular hour, UE is without any transmitting uplink data, and network side is lower than certain threshold value to the downlink data transmission of this UE, perhaps the cycle of discontinuous reception/transmission of network side and UE reaches the length of system's defined, so, network side is in order to save the power consumption of system resource or UE, the MAC layer of network side will be by upgrading the context of this UE state information of expression, the state of this UE is set to be under the activated state but is not energy-saving mode of informing network side all when at every turn carrying out the sub-district gravity treatment, and by the signaling mode, notifies this UE that the state of this UE is updated to energy-saving mode; Perhaps, by the mode of timer is set in network side and UE side, monitor the state of current transfer of data or discontinuous reception/transmission simultaneously such as entering network side and UE after the activated state, if discovery satisfies condition then all starts timer, if still satisfy condition behind the timer expiry, then the MAC layer of network side and UE synchronously are updated to the state of this UE under the state of activation but are not energy-saving mode of informing network side when at every turn carrying out the sub-district gravity treatment.
Owing to be in the UE under the energy-saving mode, when changing its Serving cell, it is mode by cell selecting or gravity treatment, in the change process of Serving cell, need not to carry out Signalling exchange with network side, that is to say, even change has taken place the Serving cell of this UE, but network side can't be known this information.Therefore, when network side need be when this UE sends beep-page message, if only the Serving cell that is write down in network side sends this beep-page message, possibly can't accurately find this UE, so, can accurately find the UE (especially being in the UE of energy-saving mode) that is in state of activation by paging in order to ensure network side, the RRC of network side need determine further whether it is in energy-saving mode to the UE that is under the state of activation.
Because the energy-saving mode that enters and withdraw from of UE is that MAC layer by network side manages, therefore, when the rrc layer of network side need need to inquire about this UE to the MAC layer earlier and whether be in energy-saving mode when the UE that is in activated state send beep-page message.Such as, the rrc layer of network side is need be when the UE that is in activated state sends beep-page message, send the primitive whether this UE of inquiry is in energy-saving mode to the MAC layer, the MAC layer returns to rrc layer with Query Result by primitive, informs whether this UE of rrc layer is in energy-saving mode.If this UE is not in energy-saving mode, then enter step 250, otherwise, enter step 260.
In step 250, the rrc layer of network side sends beep-page message to the Serving cell of this UE.Specifically, because this UE is in activated state at present, but be not in energy-saving mode, that is to say, when the Serving cell of this UE changes, all necessary informing network side, therefore, network side can be known the current service cell of this UE exactly, thereby has also just guaranteed accurately to find this UE by the beep-page message towards the Serving cell of this UE.
If through inquiry, the rrc layer of network side knows that this UE is in energy-saving mode, then in this step 260, rrc layer sends this beep-page message to the predeterminable area bigger than the Serving cell scope of this UE.Wherein, predeterminable area is the overlay area of the affiliated base station of Serving cell of this UE.
Specifically, be under the state of activation as UE but be not when carrying out the sub-district gravity treatment all during the energy-saving mode of informing network side at every turn, if the Target cell during this UE re-selecting cell belongs to different base-station nodes with the cell-of-origin, then the position of this UE of informing network side is upgraded.Such as, cell-of-origin during this UE re-selecting cell belongs to base-station node A, and the Target cell during this UE re-selecting cell belongs to base-station node B, so when this UE carries out the sub-district gravity treatment, need the renewal of its position of informing network side, make network side that the base-station node under its Serving cell is changed to base-station node B.Therefore, if UE is in energy-saving mode, then network side can send beep-page message by the overlay area of base station under the Serving cell of this UE, accurately finds this UE that is under the energy-saving mode.
The paging system of UE among the second execution mode LTE of the present invention, its structure as shown in Figure 3.
The MAC layer that comprises in network side is used to manage UE and enters and withdraw from energy-saving mode, and the UE under this energy-saving mode is in activated state but is not informing network side when at every turn carrying out the sub-district gravity treatment.
The rrc layer that comprises in network side is except being used for management control Radio Resource, also be used for need be when the UE that is in activated state sends beep-page message, by with the primitives interoperation of MAC layer, inquire about this UE to the MAC layer and whether be in energy-saving mode, if, then send this beep-page message to the predeterminable area bigger than the Serving cell scope of this UE, otherwise, this beep-page message sent to the Serving cell of this UE.
Wherein, predeterminable area is the overlay area of the affiliated base station of Serving cell of this UE.And, when this UE when being in energy-saving mode, if the Target cell during this UE re-selecting cell belongs to different base-station nodes with the cell-of-origin, then with the update notification network side of its position, to guarantee that network side can send beep-page message by the overlay area of base station under the Serving cell of this UE, accurately finds this UE that is under the energy-saving mode.
Similarly, in the present embodiment, whether the rrc layer of network side is in energy-saving mode by the UE that is under the activated state to the inquiry of MAC layer, and in corresponding scope, sending beep-page message according to Query Result, guaranteed that network side can accurately find the UE that is in state of activation by paging, particularly can paging to the UE that is in energy-saving mode.
Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
