Better understand for the ease of those skilled in the art, be elaborated below in conjunction with accompanying drawing and specific embodiment.
The basic thought of the embodiment of the invention is that MS and BS are through upgrading the monitoring carrier wave of this MS in the reciprocal process of position updating request/response message.
The embodiment of the invention one provides a kind of method of monitoring carrier wave updating, and is as shown in Figure 1, and this method comprises:
MS sends location update request message, and MS carries a monitoring carrier wave updating indication that is used to indicate monitoring carrier wave updating in this request message, and optional, MS can also carry the monitoring carrier wave that a monitoring carrier wave index recommends to BS this MS.If carrying above-mentioned monitoring carrier wave index in this request message, MS do not represent that MS will send the monitoring carrier wave that the used carrier wave of location update request message is recommended as this MS.
Step 102 is sent the response message to location update request message, and promptly response message is upgraded in the position, is the terminal updating monitoring carrier wave;
BS sends the position and upgrades response message, can in this response message, carry a monitoring carrier wave index, informs the carrier wave of its monitoring carrier wave of MS for this monitoring carrier wave index indication.If BS in this response message, do not carry above-mentioned monitoring carrier wave index so BS just accept the monitoring carrier wave that MS recommends.
BS is that the concrete grammar of terminal updating monitoring carrier wave is following: carried the monitoring carrier wave index if response message is upgraded in the position in the step 102, then BS is with the carrier wave of this monitoring carrier wave index indication monitoring carrier wave as corresponding MS; Otherwise, if carried the monitoring carrier wave index in the location update request message that MS sends in the step 101, then in BS the location update request message that MS is sent the carrier wave of monitoring carrier wave index indication as the monitoring carrier wave of this MS; If do not carry the monitoring carrier wave index in the location update request message that MS sends in the step 101, then BS sends the monitoring carrier wave of the carrier wave at location update request message place as this MS with MS.
Through the method that the embodiment of the invention one provides, MS has only a monitoring carrier wave, need on each available carrier wave, not monitor the beep-page message of BS, has saved the power supply energy consumption.Simultaneously, BS only on a carrier wave for MS transmission beep-page message, saved interface-free resources.
The embodiment of the invention two upgrade with the position of IEEE 802.16e system and the flow process of paging in monitoring carrier wave updating be that example describes.
Referring to Fig. 2, a kind of monitoring carrier wave updating method comprises:

Step 202, MS is according to ranging code of ranging code Information Selection and on carrier wave i, send;
When MS found that the monitoring carrier wave load unavailable or monitoring carrier wave of oneself surpasses certain limit, no matter what reason, as long as monitoring carrier wave is switched in the MS decision, MS can select to initiate the flow process that the position is upgraded.
Step 203, BS sends RNG-RSP (Ranging Response, ranging response) message response ranging code;
Step 204, BS is next step distance measurement request that will send of MS (Ranging Request:RNG-REQ) distribution of messages resource on carrier wave i through UL-MAP (Uplink Media Access Protocol, up media access protocol) message;
Step 205, the resource that MS distributes on the carrier wave i in step 204 is sent RNG-REQ;
The location update request message of IEEE802.16e realizes through RNG-REQ message.The embodiment of the invention is through distance measurement request purpose TLV (Type Length Value in the RNG-REQ message; Type lengths values) carries the monitoring carrier wave updating indication; The method that increases this indication has a variety of two kinds of providing wherein here: expansion distance measurement request purpose TLV upgrades indication in existing position, and a perhaps newly-increased monitoring carrier wave changes indication.No matter be that indication is upgraded in the existing position of expansion or a newly-increased monitoring carrier wave changes indication, can reach the purpose that monitoring carrier wave is upgraded in indication.MS can recommend the monitoring carrier wave of oneself through newly-increased monitoring carrier wave index TLV simultaneously.
Step 206, BS sends the RNG-RSP ranging response message, for MS upgrades monitoring carrier wave;
The position of IEEE 802.16e is upgraded response message and is realized through RNG-RSP message.BS can confirm the request that monitoring carrier wave changes in the step 205 through RNG-RSP message in the embodiment of the invention.BS also can recommend new monitoring carrier wave to give MS simultaneously.If the monitoring carrier wave that BS need recommend is given MS, then need in this ranging response message, carry the information of the monitoring carrier wave that needs recommendation, for example monitoring carrier wave index TLV.
The method of upgrading monitoring carrier wave for MS is following: if the RNG-RSP message in the step 206 has been carried monitoring carrier wave index TLV, then BS is with the carrier wave of this monitoring carrier wave index TLV indication monitoring carrier wave as corresponding MS; Otherwise, if carried monitoring carrier wave index TLV in the RNG-REQ message that MS sends in the step 205, then in BS the RNG-REQ message that MS is sent the carrier wave of monitoring carrier wave index TLV indication as the monitoring carrier wave of this MS; If do not carry monitoring carrier wave index TLV in the RNG-REQ message that MS sends in the step 205, then BS sends the monitoring carrier wave of the carrier wave at RNG-REQ message place as this MS with MS.
Step 207, BS sends beep-page message for this MS on the monitoring carrier wave of MS;
Step 208, MS carries out corresponding action according to the indication in the beep-page message.
MS receives on carrier wave i carrying out corresponding action according to the indication in the beep-page message after the paging of oneself, the action that for example networks.
Present embodiment is expanded the renewal indication of the existing position of distance measurement request purpose length type value in RNG-REQ message method is following.The range finding purpose that changes RNG-REQ message is indicated the definition of the middle bit 1 of TLV (Type Length Value, length type value) of (Ranging PurposeIndication): represent when bit 1 puts 1 that MS need change the indication of monitoring carrier wave.Concrete grammar is following:
| Title | Type | Length | Value |
