Description
Technical field
The present invention relates to the communications field, relate in particular to the double-mode mobile telephone of a kind of PHS of having and VoWLAN function.
Background technology
Because the cheap operation cost and the speech data service of high performance price ratio, PHS (Personal Handy System) network obtains large-scale application.The user can insert the PHS network by the PHS mobile phone and obtain the data/voice service, obtains mobility easily when enjoying cheap communication cost.
WLAN (WLAN WLAN (wireless local area network), Wireless Local Area Network) is being used at present on a large scale as a kind of data access service means, has laid a large amount of wlan networks at home/business/hot zones.WLAN is just becoming acquisition and is telling the main means of mobile data service.At present, IEEE 802.11 agreements promptly belong to the mechanics of communication in WLAN field.Network based on 802.11b is the main flow of wlan network, based on the high express network of 802.11g also in popularization.
VoIP (Voice over Internet Protocol) as IP-based voice service technology owing to its cheap price, more and more be subjected to telecom operators and enterprise customer's favor before the configuration purpose easily.Especially, because the appearance of WLAN makes to make utilization VoIP overWLAN (VoWLAN) technology voip technology have mobility and become a reality.
WLAN (wireless local area network) is because the general occasion that only is deployed with access point on family, office building, airport etc. of the restriction of network coverage is used, and under this occasion, the user can obtain the data access service than higher speed.For PHS, because the scope of disposing is wider at present, the whole city covers often, and this makes the user that the data communication service that PHS inserts and utilizes it to provide can be provided anywhere.But PHS is because the restriction of technology self, there is certain limitation aspect the solution spreadability, especially be difficult to lay the place of base station for family etc., but this class region network can be arranged wlan network easily, therefore, and by in conjunction with these two kinds of voice technologies, not only can solve the PHS covering problem, make the user can enjoy the voice service of cheap ground whenever and wherever possible, but also can offer the ability of user's high-speed data online, have good using value.We can say that these two kinds of technology are complementary, can allow the user according to different occasions, enjoy wireless data service whenever and wherever possible.
The design limitations of WLAN chipset and bigger power consumption have restricted the WLAN technology in handheld device, the especially application in regular handset field, have correspondingly hindered the exploitation and the popularization that utilize WLAN to carry out application such as Speech Communication.The volume of WLAN chipset and VoIP chipset can't adapt to the trend of current phone design " light, thin, short, little " more greatly, makes it be not suitable for being applied in the handheld mobile communication field; In addition, this class chip power-consumption has shortened the stand-by time of mobile phone greatly, has increased the puzzlement in user's use.
Yet, being accompanied by the raising of chip integration, these problems also are resolved step by step.For example, present Wi-Fi chip has had higher integrated level, allows the integrated subsystem that is necessary on single 802.11b and/or 802.11g communication chip, comprises radio frequency, base band and media interviews control (MAC) module.Chip is reduced on volume, and power consumption also can be lower, especially at most " sleep " or " stand-by " state in the runtime of using at Wi-Fi.The manufacturing cost of this class integrated chip also product than original is lower, has had manufacturer of a few family to begin to produce this integrated chip now.
For the WLAN enterprise IP phone that voice communication applications is provided merely, the dual-mode handset of integrated WLAN function and regular handset function then has more vast market space.Mobile phone can be realized commercial IP phone after being equipped with WLAN: be used as regular handset at ordinary times, then can use IP phone by WLAN in office.Meanwhile, the user can also insert Internet at a high speed in hot spot coverage.
Though being improved to of chip technology realized PHS and VoWLAN dual-mode handset and established solid foundation that simple chip portfolio still can't satisfy the needs of mobile phones design under present technical conditions, can not realize PHS and VoWLAN bimodulus.Therefore, need reasonably be connected, make up, be provided with the VoWLAN chip and reduce that the WLAN chip occupies circuit board space, what reduce its power consumption then is key point PHS.
Do not retrieve at present the relevant product information or the patent documentation of PHS and VoWLAN dual-mode handset.
